（2020·新课标III卷，C） With the young unable to afford to leave home and the old at risk of isolation(孤独), more families are choosing to live together.
The doorway to peace and quiet, for Nick Bright at least, leads straight to his mother-in-law, she lives on the ground floor, while he lives upstairs with his wife and their two daughters.
Four years ago they all moved into a three-storey Victorian house in Bristol - one of a growing number of multigenerational families in the UK living together under the same roof. They share a front door and a washing machine, but Rita Whitehead has her own kitchen, bathroom, bedroom and living room on the ground floor.
“We floated the idea to my mum of sharing at a house,” says Kathryn Whitehead. Rita cuts in: “We spoke more with Nick because I think it’s a big thing for Nick to live with his mother-in-law.”
And what does Nick think? “From my standpoint, it all seems to work very well. Would I recommend it? Yes, I think I would.”
It’s hard to tell exactly how many people agree with him, but research indicates that the numbers have been rising for some time. Official reports suggest that the number of households with three generations living together had risen from 325,000 in 2001to 419,000 in 2013.
Other varieties of multigenerational family are more common. Some people live with their elderly parents; many more adult children are returning to the family home, if they ever left. It is said that about 20% of 25-34-year-olds live with their parents, compared with 16% in 1991.The total number of all multigenerational households in Britain is thought to be about 1.8 million.
Stories like that are more common in parts of the world where multigenerational living is more firmly rooted. In India, particularly outside cities, young women are expected to move in with their husband’s family when they get married.
31．What is the text mainly about?
A．Lifestyles in different countries. B．Conflicts between generations.
C．A housing problem in Britain. D．A rising trend of living in the UK.
【解析】31．主旨大意题。通读全文，尤其根据第一段“With the young unable to afford to leave home and the old at risk of isolation(孤独), more families are choosing to live together.”可知，由于年轻人负担不起离家的费用，而老年人又面临着被孤立的风险，越来越多的家庭选择住在一起。所以短文主要是关于英国生活方式的一种上升趋势。故选D项。
（2020·新课标I卷，D） The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.
One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.
In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.
Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.
35．Which of the following can be the best title for the text?
A．Can we grow more glowing plants?
B．How do we live with glowing plants?
C．Could glowing plants replace lamps?
D．How are glowing plants made pollution-free?
【解析】35．主旨大意题。根据最后一段中Lighting accounts for about 7%of the total electricity consumed in the US. Since lighting is often far removed from the power source-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission. Glowing plants could reduce this distance and therefore help save energy.可知照明约占美国总耗电量的7%。由于照明通常远离电源，例如从发电厂到偏僻公路上路灯的距离，在传输过程中会损失大量能源。发光的植物可以缩短这段距离，从而帮助节约能源。结合文章主要说明了绿色植物对人们很有好处，因此麻省理工学院的工程师开发了一种发光植物，文章介绍了他们发明这种植物的过程，以及这种植物的一些优势，指出在未来发光植物有可能取代路灯，达到节约能源的作用。由此可知，C选项“发光的植物能取代路灯吗？”最符合文章标题。故选C。
Lacrosse (曲棍球) is a popular sport in Canada. The Indians in Canada invented it. They used it to train for war. They invented this game before Columbus arrived in the New World.
People play lacrosse outdoors. The lacrosse field is seven meters long. At each end of the field there is a goal. The goal is a net. There are ten players on each team. Each player has a stick called “ cross”. The player hit a ball into the net as many times as possible. Lacrosse is a very fast game because the players can catch and pass the ball at a high speed with their sticks. Players often get great fun it playing lacrosse.
There are many lacrosse clubs and lacrosse teams all over Canada. Every night Canadians can watch the lacrosse games on TV or listen to the lacrosse games over the radio.
At one time lacrosse was the national summer sport in Canada. Today it is still popular with Canadians.
1.The passage is mainly about ___________.
A. How to Play Lacrosse
B. Lacrosse in Canada
C. The History of Lacrosse

（2020·新课标II卷，D） I have a special place in my heart for libraries. I have for as long as I can remember. I was always an enthusiastic reader, sometimes reading up to three books a day as a child. Stories were like air to me and while other kids played ball or went to parties, I lived out adventures through the books I checked out from the library.
My first job was working at the Ukiah Library when I was 16 years old .It was a dream job and I did everything from shelving books to reading to the children for story time.
As I grew older and became a mother, the library took on a new place and an added meaning in my life. I had several children and books were our main source(来源) of entertainment. It was a big deal for us to load up and go to the local library, where my kids could pick out books to read or books they wanted me to read to them.
I always read ,using different voices ,as though I were acting out the stories with my voice and they loved it !It was a special time to bond with my children and it filled them with the wonderment of books .
Now, I see my children taking their children to the library and I love that the excitement of going to the library lives on form generation to generation.
As a novelist, I’ve found a new relationship with libraries. I encourage readers to go to their local library when they can’t afford to purchase a book. I see libraries as a safe haven(避风港) for readers and writers, a bridge that helps put together a reader with a book. Libraries, in their own way, help fight book piracy(盗版行为) and 1 think all writers should support libraries in a significant way when they can. Encourage readers to use the library. Share library announcements on your social media. Frequent them and talk about them when you can.
35．Which can be a suitable title for the text?
A．Reading: A Source of Knowledge
B．My Idea about writing
C．Library: A Haven for the Young
D．My Love of the Library
The Sahara Festival is a celebration of the very recent past. The three-day event is not fixed to the same dates each year, but generally takes place in November or December. It is well attended by tourists, but even better attended by locals.
During the opening ceremonies, after the official greetings from the government leaders, people who attend the festival begin to march smartly before the viewing stands, and white camels transport their riders across the sands. Horsemen from different nations display their beautiful clothes and their fine horsemanship. One following another, groups of musicians and dancers from all over the Sahara take their turn to show off their wonderful traditional culture. Groups of men in blue and yellow play horns and beat drums as they dance in different designs. On their knees in the sand, a group of women in long dark dresses dance with their hair: their long, dark, shiny hair is thrown back and forth in the wind to the rhythm of their dance.
67. This passage mainly tells readers_______.
A. what happens on the opening day of the Sahara Festival
B. how people celebrate during the three-day Sahara Festival
C. what takes place at the closing ceremonies of the Sahara Festival

（2020·湖南高三二模） I live in a small studio.I sleep in a bed that folds down from the wall.I have six dress shirts.I have 10 shallow bowls that I use for salads and main dishes.When people come over for dinner.I pull out my extendable dining room table.I don't have a single CD or DVD and I have 10 percent of the books I once did.
I have come a long way from the life I had in the late’90s,when,having made a fortune from an Internet start-up sale,I had a giant house full of stuff(物品)-electronics and cars and appliances and furniture.
Somehow this stuff ended up running my life,or a lot of it;the things I consumed ended up consuming me.My life became unnecessarily complicated.There were lawns(草坪)to mow,floors to mop,a car to insure,wash,refuel,repair and register and tech to set up and keep working.Who had I become?My house and my things were my new employers for a job I had never applied for.I started to wonder why my theoretically upgraded life didn't feel any better and why I felt more anxious than before.
For me,it took 15 years to get rid of the things I had collected and live a bigger,better,richer life with less.
I like material things as much as anyone.I studied product design in school.But my experiences show that after a certain point,material objects have a tendency to crowd out the emotional needs they are meant to support.I know the best stuff in life isn't stuff at all,and that relationships,experiences and meaningful work are the main parts of a happy life.
My latest project is to design thoughtfully constructed small homes that support our lives,not the other way around.The house 1 design contains less stuff and makes it easier for owners to live within their means and to limit their environmental footprint.My space is well-built,affordable and as functional as living spaces twice the size.I frequently have dinner parties for 12.I sleep better knowing I'm not using more resources than I need.I have less-and enjoy more.
My space is small.My life is big.

When “Rise of the Planet of the Apes” was first shown to the public last month, a group of excited animal activists gathered on Hollywood Boulevard. But they weren’t there to throw red paint on fur-coat-wearing film stars. Instead, one activist, dressed in a full-body monkey suit, had arrived with a sign praising the filmmakers: “Thanks for not using real apes (猿)!”
The creative team behind “Apes” used motion-capture (动作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that records an actor’s performance and later processes it with computer graphics to create a final image (图像). In this case, one of a realistic-looking ape.
Yet “Apes” is more exception than the rule. In fact, Hollywood has been hot on live animals lately. One nonprofit organization, which monitors the treatment of animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year. Already, a number of films, including “Water for Elephants,” “The Hangover Part Ⅱ” and “Zookeeper,” have drawn the anger of activists who say the creatures acting in them haven’t been treated properly.
In some cases, it’s not so much the treatment of the animals on set in the studio that has activists worried; it’s the off-set training and living conditions that are raising concerns. And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the States.
24．Why did the animal activists gather on Hollywood Boulevard?
A．To see famous film stars.
B．To oppose wearing fur coats.
C．To raise money for animal protection.
D．To express thanks to some filmmakers.
25．What does paragraph 2 mainly talk about?
A．The cost of making “Apes.”
B．The creation of digitalized apes.
C．The publicity about “Apes.”
D．The performance of real apes.
26．What does the underlined phrase “keeping tabs on” in paragraph 3 probably mean?
27．What can we infer from the last paragraph about animal actors?
A．They may be badly treated.
B．They should take further training.
C．They could be traded illegally
D．They would lose popularity.
Today's world is not an easy adjustment for young adults. Key skill set for success is persistence (毅力), a characteristic that researchers say is heavily influenced by fathers. Researchers from Brigham Young University discovered that fathers are in a unique position to help their adolescent children learn persistence.
BYU professors Laura Padilla-Walker and Randal Day arrived at these findings after following 325 American families over several years. And over time，the persistence gained through fathers led to higher achievement in school.
"There are relatively few studies that stress the unique role of fathers，"Padilla-Walker said. "This research also helps to prove that characteristics such as persistence-which can be taught-are key to a child's life success.”
Researchers determined that dads need to practice an "authoritative" parenting style. Authoritative parenting is not authoritarian:rigid，demanding or controlling. Rather，an authoritative parenting style includes some of the following characteristics:children feel warmth and love from their father；responsibility and the reasons behind rules are stressed children are given an appropriate level of autonomy(自主权).
In the study，about 52 percent of the dads exhibited above-average levels of authoritative parenting. A key finding is that over time，children raised by an authoritative father were significantly more likely to develop persistence，which leads to better outcomes in school.
This particular study examined 11 to 14-year-olds living in two-parent homes. Yet the researchers suggest that single parents still may play a role in teaching the benefits of persistence，which is an avenue of future research.
27．What is special about the BYU professors' study?
A．It centered on fathers' role in parenting.
B．It was based on a number of large families.
C．It analyzed different kinds of parenting styles.
D．It aimed to improve kids' achievement in school.
28．What would an authoritative father do when raising his children?
A．Ignore their demands. B．Make decisions for them.
C．Control their behaviors. D．Explain the rules to them.
29．Which group can be a focus of future studies according to the researchers?
B．Children aged from 11 to 14.
D．Mothers in two-parent homes.
30．Which of the following is the best title for the text?
A．Three Characteristics of Authoritative Fathers.
B．Key Skills for Young Adults to Succeed in Future.
C．Children Tend to Learn Determination from Father.
D．Family Relationship Influences School Performance.
We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C．Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.
32．What does the author want to tell us by the examples in paragraph 1?
A．Environmental adaptation of cattle raisers. B．New knowledge of human evolution.
C．Recent findings of human origin. D．Significance of food selection.
33．Where do the Bajau build their houses?
A．In valleys. B．Near rivers. C．On the beach. D．Off the coast.
34．Why was the young Jubilado astonished at the Bajau?
A．They could walk on stilts all day. B．They had a superb way of fishing.
C．They could stay long underwater. D．They lived on both land and water.
35．What can be a suitable title for the text?
A．Bodies Remodeled for a Life at Sea B．Highlanders’ Survival Skills
C．Basic Methods of Genetic Research D．The World’s Best Divers
For people, who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today’s sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.
Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can’t let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device(LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.
For those who hunger for some peace and quiet, sound can now create silence. Let’s say you are at the airport, and the little boy on the seat next to you is humming(哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target, and your peace and quiet comes back.
Directed sound is a new technology that allows companies to use sound in much the same way spotlights(聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, “spotsound” creates a circle of sound in on targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.
46. What could be inferred from Paragraph 2 about the effect of the LRAD?
A. It causes temporary hearing loss.
B. It slows down a running man.
C. It makes it easy to identify a suspect.
D. It keeps the suspect from hurting others.
47. The Silence Machine is a device specially designed to ________.
A. silence the people around you
B. remove the sound of commercials
C. block the incoming sound waves
D. stop unwanted sound from affecting you
48. What feature do spotsounds and spotlights share?
A. They travel in circles.
B. They clear the atmosphere.
C. They can be transformed into energy.
D. They can be directed onto a specific area.
49. Directed sound can be used for ________.
A. creative designs of restaurant menus
B. ideal sound effects on the theater stage
C. different choices of music for businesses
D. strict control over any suspicious customer
50. What does the passage focus on?
A. How professionals invented sound products.
B. Inventions in the field of sound technology.
C. The growing interest in the study of sound.
D. How sound engineers work in their studios.
I must have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don't remember mom reading me a storybook by my bedside. I was extremely inspired by the elegant way the words sounded.
I always wanted to know what my mom was reading. Hearing mom say," I can't believe what's printed in the newspaper this morning," made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.
This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said," The C-A-N-D-Y is hidden on the top shelf," I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.
Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A's on my tests. Occasionally, I would read a novel that was assigned, but I didn't enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract left too much room for argument.
Yet, now that I'm growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don't have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.
We're taught to read because it's necessary for much of human understanding. Reading is a vital part of my life. Reading satisfies my desire to keep learning. And I've found that the possibilities that lie within books are limitless.
41. Why did the author want to grab the newspaper out of mom's hands？
A. She wanted mom to read the news to her.
B. She was anxious to know what had happened.
C. She couldn't wait to tear the newspaper apart.

D. her growing desire to know the world around her.
43. What was the author's view on factual reading？
A. It would help her update test-taking skills.
B. It would allow much room for free thinking.
C. It would provide true and objective information.
D. It would help shape a realistic and serious attitude to life.
44. The author takes novel reading as a way to___________.
A. explore a fantasy land
B. develop a passion for leaning
C. learn about the adult community
D. get away from a confusing world
45. What could be the best title for the passage？
A. The Magic of Reading B. The Pleasure of Reading
C. Growing Up with Reading D. Reading Makes a Full Man
During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.
Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.
Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those least liked in elementary school, are “most likely to engage(从事)in dangerous and risky behavior.”
In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys(调查研究). “We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us."
Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date-sharing, kindness, openness — carry over to later years and make you better able to relate and connect with others.
In analyzing his and other research，Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. "Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage, ” he said.
32. What sort of girl was the author in her early years of elementary school?
A. Unkind. B. Lonely. C. Generous. D. Cool.
33. What is the second paragraph mainly about？
A. The classification of the popular.
B. The characteristics of adolescents.
C. The importance of interpersonal skills.
D. The causes of dishonorable behavior
34. What did Dr. Prinstein’s study find about the most liked kids?
A. They appeared to be aggressive.
B. They tended to be more adaptable.
C. They enjoyed the highest status.
D. They performed well academically.
35. What is the best title for the text?
A. Be Nice-You Won’t Finish Last
B. The Higher the Status, the Beer
C. Be the Best-You Can Make It
D. More Self-Control, Less Aggressiveness
Bacteria are an annoying problem for astronauts. The microorganisms(微生物) from our bodies grow uncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA overcoming this very tiny big problem? It’s turning to a bunch of high school kids. But not just any kids. It depending on NASA HUNCH high school class, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.
HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon’s students have been studying ways to kill bacteria in zero gravity, and they think they’re close to a solution(解决方案). “We don’t give the students any breaks. They have to do it just like NASA engineers,” says Florence Gold, a project manager.
“There are no tests,” Gordon says. “There is no graded homework. There almost are no grades, other than‘Are you working towards your goal?’ Basically, it’s ‘I’ve got to produce this product and then, at the end of year, present it to NASA.’ Engineers come and really do an in-person review, and…it’s not a very nice thing at time. It’s a hard business review of your product.”
Gordon says the HUNCH program has an impact(影响) on college admissions and practical life skills. “These kids are so absorbed in their studies that I just sit back. I don’t teach.” And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.
32. What do we know about the bacteria in the International Space Station?
A. They are hard to get rid of. B. They lead to air pollution.
C. They appear different forms. D. They damage the instruments.
33. What is the purpose of the HUNCH program?
A. To strengthen teacher-student relationships. B. To sharpen students’ communication skills.
C. To allow students to experience zero gravity. D. To link space technology with school education
34. What do the NASA engineers do for the students in the program?
A. Check their product. B. Guide project designs
C. Adjust work schedules. D. Grade their homework.
35. What is the best title for the text?
A. NASA: The Home of Astronauts.
B. Space: The Final Homework Frontier.
C. Nature: An Outdoor Classroom.
D. HUNCH:A College Admission Reform.
The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year，half of the calls we receive will be scams(欺诈).We are finally waking up to the severity of the problem by supporting and developing a group of tools，apps and approaches intended to prevent scammers from getting through. Unfortunately，it's too little，too late. By the time these “solutions"(解决方案)become widely available，scammers will have moved onto cleverer means. In the near future，it's not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.
That's because there are a number of powerful voice manipulation ( 处理 ) and automation technologies that are about to become widely available for anyone to use .At this year's I/O Conference ,a company showed a new voice technology able to produce such a convincing human –sounding voice that it was able to speak to a receptionist and book a reservation without detection.
These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision A decade of data breaches(数据侵入)of personal information has led to a situation where scammers can easily learn your mother 's name ，and far more. Armed with this knowledge. they're able to carry out individually targeted campaigns to cheat people. This means. for example，that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller 's，ricking you into "confirming " your address，mother's name，and card number. Scammers follow money，so companies will be the worst hit. A lot of business is still done over the phone，and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.
We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by. or abandoning phone calls altogether and moving towards data-based communications—using apps like Face Time or WhatsApp, which can be tied to your identity.
Credibility is hard to earn but easy to lose, and the problem is only going to harder from here on out.

Good Morning Britain’s Susanna Reid is used to grilling guests on the sofa every morning, but she is cooking up a storm in her latest role — showing families how to prepare delicious and nutritious meals on a tight budget.
In Save Money: Good Food, she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste, while preparing recipes for under £5 per family a day. And the Good Morning Britain presenter says she’s been able to put a lot of what she’s leant into practice in her own home, preparing meals for sons, Sam,14, Finn,13, and Jack, 11.
"We love Mexican churros, so I buy them on my phone from my local Mexican takeaway restaurant," she explains. "I pay £5 for a portion(一份), but Matt makes them for 26p a portion, because they are flour, water, sugar and oil. Everybody can buy takeaway food, but sometimes we’re not aware how cheaply we can make this food ourselves. "
The eight-part series(系列节目), Save Money: Good Food, follows in the footsteps of ITV’s Save Money: Good Health, which gave viewers advice on how to get value from the vast range of health products on the market.
With food our biggest weekly household expense, Susanna and Matt spend time with a different family each week. In tonight’s Easter special they come to the aid of a family in need of some delicious inspiration on a budget. The team transforms the family’s long weekend of celebration with less expensive but still tasty recipes.

We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.
Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t
even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂
In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂
Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.

Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness(荒野). But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.
Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warming. An avalanche(雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.
But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.

My First Marathon（马拉松）
A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.
I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. I didn’t do either well. He later informed me that I was ＂not athletic＂.
The idea that I was ＂not athletic＂ stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!
The night before my marathon, I dreamt that I couldn’t even find the finish line. I woke up sweating and nervous, but ready to prove something to myself.
Shortly after crossing the start line, my shoe laces(鞋带) became untied. So I stopped to readjust. Not the start I wanted!
At mile 3, I passed a sign: ＂GO FOR IT, RUNNERS!＂
By mile 17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.
By mile 21, I was starving!
As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.
I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.
Determined to be myself, move forward, free of shame and worldly labels(世俗标签), I can now call myself a ＂marathon winner＂.

At the World Economic Forum last month, President Trump drew claps when he announced the United States would respond to the forum's proposal to plant one trillion(万亿) trees to fight climate change. The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded that planting so many trees was “the most effective climate change solution to date”.
If only it were true. But it isn't. Planting trees would slow down the planet's warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and considerable reductions in carbon release from fossil fuels, to net zero by 2050.
Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to balance the carbon release from your driving. That's clearly no more than disaster slightly delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.
There is no way that planting trees, even across a global area the size of the United States, can absorb the huge amounts of fossil carbon released from industrial societies. Trees do take up carbon from the atmosphere as they grow. But this uptake merely replaces carbon lost when forests were cleared in the first place, usually long ago. Regrowing forests where they once grew can undo some damage done in the past, but even a trillion trees can't store enough carbon to head off dramatic climate changes this century.
In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claim that global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”.

Spending over a year in the bleak (荒凉的) Antarctica might change your brain for the worse, according to new research out this month. It seems to show that polar explorers who lived for 14 months at an Antarctica research station experienced brain shrinkage, likely as a result of their loneliness and boredom.
The study’s authors used MRI (核磁共振) to scan the brains of eight members of a team before they began a long stay at the German-run research station. During their mission. the team periodically took tests of their cognition and memory and provided blood samples that allowed the study authors to measure their levels of a protein important for brain health called brain-derived neurotrophic factor (BDNF). When they returned, they had their brains scanned again.
Finally, compared to themselves before the mission, the explorers' brains appeared to have less grey matter on average. The shrinkage was most apparent in the hippocampus, in area of the brain key to memory and cognition. Their average levels of BDNF also dropped during the trip and didn’t improve significantly even after one-and-a-half months back home.
The study's findings, published in The New England Journal of Medicine, aren't the first to suggest that long time of being separated can change the brain. But practically all of this work has involved animals, according to the researchers.
Of course, an eight-person study is small, so any of its conclusions should be taken with caution. Lead author Alexander C．Stahn, now a researcher at the Perelman School of Medicine at the University of Pennsylvania, said that the effects on the hippocampus are likely temporary, provided the scientists returned back to a life filled with social interaction and interesting things to see.
Still, since people will continue traveling to and from Antarctica for long periods of time, the findings are definitely worth keeping in mind and exploring further. They might even prove relevant for the rare few people who might travel as far as Mars in the future — perhaps the only similarly scientific, months-long mission that would be even more lonely.

A．They were no longer used to the civilized world.
B．They had some difficulty in remembering things.
C．They became normal after one-and-a-half months.
D．They published their findings in a medical magazine.
4．What can we learn about the study?

Kevin Randall, a teacher,who teaches biology at Grandville High School,runs the environmental club at the high school,which has around 2,000 students.The club is known as the GHS Green Team,and it aims to raise awareness among students and teachers about sustainability(持续性).It also works on projects to reduce the environmental footprint of the building itself.
One of the club's recent projects focused on reducing waste in the school cafeteria.Randall said their cafeteria supervisor told them that the school went through 54,000 plastic forks every year.The club applied for a financial help,built recycling centers for the cafeteria,and purchased metal silverware.
And now every student uses a durable metal fork or a spoon instead of disposables.(一次性用品),“and that's just one way we're trying to capture the low-hanging fruit,if you will,"Randall said.
The efforts of Randall and his students have earned Grandville High School the Michigan Green School certification from the state.In addition to their work reducing waste in the cafeteria, the GHS Green Team has also built a garden with flowers and vegetables on campus,and leads cleanups on site and out in the community.Over the years,Randall and his students have also been working on raising money to install solar panels(太阳能板) on the roof of the high school.
Randall said he was motivated to take the lead on environmental issues for his school because he wanted his students to have someone to turn to in the building who understands what's at stake(利害攸关）when it comes to climate change.
＂And I also felt like I needed to do more in my life for my own two children at home," Randall added,"They need to know that their dad is working as hard as he can to reduce the effects of climate change,and to spread the word,and to make sure that other students out there are learning about this just the way they are at home."
1．What is the purpose of the GHS Green Team club?
A．To inspire students' love for biology.
B．To finish the projects assigned by school.
C．To prepare students for their future jobs.
D．To promote environmental protection.
2．What's the result of the project on school cafeteria?
A．It has changed the outlook of the cafeteria.
B．Students can have more fruits in the cafeteria.
C．Plastic forks are no longer used in the cafeteria.
D．The school has become famous nationwide.
3．What's the fourth paragraph mainly about?
A．The classification of the projects.
B．The characteristics of the club.
C．The activities organized by the club.
D．The future of the club.
4．What was Randall's aim by doing the work on environmental issues?.
A．To educate the young.
B．To get material rewards.
C．To amuse his children.
D．To make himself famous.
Fathers have a strong influence on their children. And one of the areas in which researchers look for the influence is in the development of language. What begins with gestures and sounds develops into competence with language by around age 3.Fathers are proving to be an important part of this process, as Lynne Vernon-Feagans of the University of North Carolina and her colleagues are finding out.
They have done some of the most interesting work looking at children's language development in both middle-class and poor, rural families. They've found, to their surprise, that not only are fathers important for children’s language development, but that fathers matter more than mothers. For example, they found that fathers' use of vocabulary when reading picture books to their children at 6 months of age was significantly related to the children's expressiveness at 15 months and use of advanced language at age 3.This held true no matter what the mother's educational level was or how she spoke to the children.
Vernon-Feagans was surprised by the difference between mothers and fathers. She had thought they would be equally involved in encouraging their children’s language development. Why would fathers be more important in this regard than mothers? Maybe it's because mothers are more familiar with their kids, typically spending more time with them than fathers do. That makes mothers more likely to choose words the kids know. Fathers aren't as familiar with their kids,so they use a broader vocabulary, and the kids learn new words and concepts as a result.
Vernon-Feagans thought there might be another factor at play as well. Because fathers usually spend less time with their kids, they are more of a novelty. That makes them more interesting playmates. “I do think our children see it as very special when they do book reading with their fathers,” she said. “They may listen more and acquire language in a special way.”
The researchers found that wealthier fathers produced a greater rise in their children’s IQs than did similarly active low-income fathers. It might sound discouraging, but it suggests that improving men's educational or financial status would bring benefits not only to them but to their children as well.
1．What did Vernon-Feagans and her colleagues find unexpectedly in their research?
A．Mothers' improper ways to talk to children.
B．Fathers' important role in children's language.
C．Children’s use of advanced language at age 3.
D．Different vocabulary in different families.
2．What might make mothers a less important role in children’s language development?
A．Use of new words.
B．Familiarity with words.
C．Use of limited vocabulary.
D．Too much time with children.
3．What does the underlined“ a novelty” in Paragraph 4 indicate?
A．Fathers cannot afford the time with their kids.
B．Kids often complain about their fathers' absence.
C．It is quite common that fathers stay with their kids.
D．It feels new and different for kids to stay with their fathers.
4．What is the main idea of the text?
A．Fathers' social status benefits children's language.
B．Parents have different influences on children's language.
C．Children’s language abilities depend on good fathering.
D．Fathers contribute more than mothers to children's language.

2．主旨大意题。根据第三段Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. 把树木作为解决气候变化的主要办法是一种危险的转移。更糟糕的是，它把注意力从那些对碳排放负责的人身上移开，正是这些人把我们推向灾难。因此，第3段主要论述了以植树来保护环境的缺点。故选A项。
3．推理判断题。根据最后一段In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claim that global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”. Justin Gillis在《科学》杂志上发表了与去年夏天《科学》杂志公布的研究结果截然相反的观点，他认为去年夏天公布的那个研究结果是不符合地球碳循环动力学的。同时，他发出警告：通过植树来解决气候问题是不科学的，是错误的，是危险的，是具有误导性的。推测，Justin Gillis对植树提议是持反对态度的。故选B项。
1．细节理解题。根据第一段Spending over a year in the bleak (荒凉的) Antarctica might change your brain for the worse, according to new research out this month.

2．细节理解题。根据第二段The study’s authors used MRI (核磁共振) to scan the brains of eight members of a team before they began a long stay at the German-run research station. During their mission. the team periodically took tests of their cognition and memory and provided blood samples that allowed the study authors to measure their levels of a protein important for brain health called brain-derived neurotrophic factor (BDNF). When they returned, they had their brains scanned again.(该研究的作者在一个团队的8名成员开始在德国运营的研究站长期停留之前，使用核磁共振成像扫描了他们的大脑。在他们执行任务过程中，研究小组定期对他们的认知和记忆进行测试，并提供血样，使研究作者能够测量他们的一种叫做脑源性神经营养因子的蛋白质水平，这种蛋白质对大脑健康很重要。当他们返回时，再次对他们的大脑进行扫描)以及第三段Finally, compared to themselves before the mission, the explorers' brains appeared to have less grey matter on average. The shrinkage was most apparent in the hippocampus, in area of the brain key to memory and cognition. Their average levels of BDNF also dropped during the trip and didn’t improve significantly even after one-and-a-half months back home.可知，最后，与执行任务前相比，探险者的大脑平均灰质较少。海马的萎缩最为明显，海马是大脑中记忆和认知的关键区域。他们的平均BDNF水平在旅途中也有所下降，即使在回家一个半月后也没有明显改善。由此可知，科学家通过比较扫描结果得出结论。故选A。
3．推理判断题。根据第三段中Finally, compared to themselves before the mission, the explorers' brains appeared to have less grey matter on average. The shrinkage was most apparent in the hippocampus, in area of the brain key to memory and cognition.可知，最后，与执行任务前相比，探险家的大脑平均灰质较少。海马的萎缩最为明显，海马是大脑中记忆和认知的关键区域。由此可推知，当探险家返回时，他们在记忆方面有些困难。故选B。
4．细节理解题。根据第四段中The study's findings, published in The New England Journal of Medicine, aren't the first to suggest that long time of being separated can change the brain.可知，这项研究发表在《新英格兰医学杂志》上，并不是第一个表明长时间的隔绝会改变大脑的研究。由此可知，其他研究与本研究有相同的发现。故选C。
5．主旨大意题。根据最后一段Still, since people will continue traveling to and from Antarctica for long periods of time, the findings are definitely worth keeping in mind and exploring further. They might even prove relevant for the rare few people who might travel as far as Mars in the future — perhaps the only similarly scientific, months- long mission that would be even more lonely.可知，尽管如此，由于人们将在很长一段时间内继续往返于南极洲之间，这些发现绝对值得我们牢记在心，并进行进一步的探索。他们甚至可能会被证明与未来可能远行到火星的极少数人有关——也许只有类似的科学性、长达数月的任务才会更加孤独。由此可知，最后一段主要讲了这一发现的重要性。故选A。
