2021届高考英语一轮复习考点36阅读理解说明文考点归纳 试卷

考点36 阅读理解说明文
高考频度：★★★★★
说明文是对事物或事理进行客观说明的一种文体，它以说明为主要表达方式，通过解说事物或阐明事理，达到教人以知识的目的，在结构上往往采用总分、递进等方式按一定的顺序（如时间、空间、从现象到本质）进行说明。说明文的特点是客观、简练、语言准确、明了，文章很少表达作者的感情倾向。阅读说明文的重点在于读懂它说明的事物或事理，了解事物的性质、构造、成因、功能等，了解事理的含意、特点等。最近五年，说明文的出现变化不大，一直很稳定，选材通常是各学科的前沿问题；高科技领域的科研成果；人们比较关心的社会问题；人文方面的经典。由于阅读理解题的设置采用渐进式，即由简到难的方式，因此说明文是高考试卷中阅读理解题中相对比较难的，通常后置。阅读理解试题的中要考点之一是考查学生对词汇和句式的掌握。说明文的词汇和句式的运用较别的体裁的文章难度更大。词汇运用灵活，同一词的不同词性的用法交替出现，未列入考纲的生词较多，通常达到了4-5%。不过考生可以通过说明文的语言特点来帮助理解语篇，例如，下定义、解释、举例、同义词、反义词、上下义词以及标点符号（如破折号、冒号都有表示解释和说明）等。
命题方式
考向一 细节理解题
说明文中考查的细节理解题大致与记叙文相似。命题区域都有其共同点：⑴在列举处命题，如用first(1y)、second(1y)、third(1y)finally、not only„but also、then、in addition等表示顺承关系的词语列举出事实。试题要求考生从列举出的内容中选出符合题干要求的答案项。⑵在例证处命题，句中常用由as、such as、for example、for instance等引导的短语或句子作为例证，这些例句或比喻就成为命题者设问的焦点。⑶在转折对比处命题，一般通过however、but、yet、in fact等词语来引导。对比用unlike、until、not so much…as等词语引导，命题者常对用来对比的双方属性进行考查。⑷在比较处命题，无端的比较、相反的比较、偷换对象的比较，经常出现在干扰项中，考生要标记并且关注到原文中的比较，才能顺利地排除干扰。⑸在复杂句中命题，包括同位词、插入语、定语、从句、不定式等，命题者主要考查考生对句子之间的指代关系和语法关系。  
细节类问题一般都能在原文中找到出处，只要仔细就可以在文中找到答案。但正确的选择项不可能与阅读材料的原文完全相同，而是用不同的语句成句型表达相同的意思。      
考向二 语意猜测题
 说明文为了把自然规律，事物的性质等介绍清楚或把事理阐述明白，因此学术性强的生词较多，所以常进行生词词义判断题的考查。命题方式多以the underlined part … in paragraph…refers to…或what does the underlined word mean?或what is the meaning of the underlined word?为设问方式。解题时考生应认真阅读原文，分析其对某些科学原理是如何定义、如何解释的，并以此为突破口抽象概括出生词词义。也可以通过上下文来猜测某个陌生词语的语意。或者找出某个词语在文章中的同义词。要注意破折号、同位语从句、定语从句、插入语等具有解释、说明作用的语言成分。说明文在阐述说明对象时易发生动作变换、人称转变的现象，这类题目常以it，they，them 等代词为命题点，因此考生要根据上下文语境，认真阅读原文，分析动作转换背景，弄清动作不同执行者，以便准确判断代词的其实际指代对象。      
考向三 主旨大意题
    说明文常用文章大意判断题考查考生对通篇文意的理解。即对文章的主题或中心意思的概括和归纳。主要考查考生对文章的整体理解能力。命题形式常以this passage mainly talks about ____. what is the main idea of the passage? 为设问方式。
答题时首先阅读题干，掌握问题的类型，了解试题题干以及各个选项所包含的信息，然后有针对性地对文章进行扫读，对有关信息进行快速定位，再将相关信息进行整合、甄别、分析、对比，有根有据地排除干扰项，选出正确答案。  
考向四 判断推理题  
这种试题常以(1)the passage is intended to...(2) the author suggests that...(3) the story implies that…(4) which point of view may the author agree to?(5) from the passage we can conclude that...(6) the purpose of the passage is to...为设问方式。这种题型的答案在原文中不是直接就能找到的，它要求考生进行合理的推断。如因果关系，文中的某些用词、语气也往往具有隐含意义，考生要将这种含义读出来。说明文常出现图示判断题，这种试题可以事物之间正确的依赖关系为命题点，要求考生判断其正确的流程顺序相互关系等。考生一定要认真阅读原文，并对照原文介绍的情况，弄清图示的差异，根据题干需要最终做出正确判断。如：动物介绍性说明文常出现动物能力判断题，考查考生对特定动物所具有能力的判断。解题时考生应认真阅读原文对动物形态活动能力的判断，了解动物的生存环境和是否会使用工具，是否善于爬行、飞翔和游泳等。     观点态度题也是判断推理题考查的内容之一。说明文的对象为客观事实,但设题以议论的表达方式抒发对该说明对象的想法。如对某种新发明的赞赏,或对某个事物的批判。这类题目常见的题干表达方式有what was the author’s attitude towards ...? 等。

高考阅读理解中，说明文为主要体裁之一。高考阅读理解题的设问主要围绕以下四方面：细节事实题、主旨大意题、推理判断题、猜测词义题。其中，说明文主要以细节事实、主旨大意和猜测词义三方面问题为主。
一、词义猜测类题型
阅读理解题中常要求学生猜测某些单词或短语的意思。历年英语高考题中均有此类题目，有的文章尽管没有专门设题，但由于文章中常常出现生词，因此，词义的猜测还是贯穿在文章的阅读理解之中。解这类题目一般是通过上下文去理解或根据构词法去猜测。判断一个单词的意思不但离不开句子，而且还需要把句子放在上下文中，根据上下文提供的线索加以猜测。运用构词法,语境等推测关键词义，可以根据以下几种方法猜测：
（一）内在逻辑关系
根据内在逻辑关系推测词义是指运用语言知识分析和判断相关信息之间存在的逻辑关系，然后根据逻辑关系推断生词词义。
1.通过同义词和反义词的关系猜词
通过同义词猜词，一是要看由and或or连接的同义词词组，如happy and gay，即使我们不认识gay这个词，也可以知道它是愉快的意思.这是高三册第八单元阅读第五段的句子：
The word ＂secure＂ in paragraph 5 line is closest in meaning to_________.
A. freefromanxiety B. anxious C. nervous D. happy
根据上下文和同义词，可以选出答案A。
二是看在进一步解释的过程中使用的同义词，如Man has known something about the planets Venus，Mars，and Jupiter with the help of spaceships. 此句中的Venus（金星）,Mars（火星）,Jupiter（木星）均为生词，但只要知道planets就可猜出这几个词都属于＂行星＂这一义域.通过反义词猜词，一是看表转折关系的连词或副词，如but，while，however等；二是看与not搭配的或表示否定意义的词语，如：He is so homely，not at all as handsome as his brother.根据not at all...handsome我们不难推测出homely的意思，即不英俊,不漂亮的意思。
2.根据因果关系猜测词义
通过因果关系猜词，首先是找出生词与上下文之间的逻辑关系，然后才能猜词。有时文章借助关联词（如because，as，since，for，so，thus，as a result，of course，therefore等等）表示前因后果。例如：
You shouldn’t have blamed him for that，for it wasn’t his fault.通过for引出的句子所表示的原因（那不是他的错），可猜出blame的词义是＂责备＂。
3.通过定义或释义关系来推测词义
例如：But sometimes，no rain falls for a long，long time. Then there is a dry period，or drought.
从drought所在句子的上文我们得知很久不下雨，于是便有一段干旱的时期，即drought，由此可见drought意思为＂久旱＂，＂旱灾＂。而a dry period和drought是同义语。这种同义或释义关系常由is，or，that is，in other words，be called或破折号等来表示。
4.通过句法功能来推测词义
例如：Bananas，oranges，pineapples，coconuts and some other kind of fruit grow in warm areas.假如pineapples和coconuts是生词，我们可以从这两个词在句中所处的位置来判断它们大致的意思。从句中不难看出pineapples，coconuts和bananas，oranges是同类关系，同属fruit类，因此它们是两样水果，准确地说，是菠萝和椰子。
5.通过描述猜词
描述即作者为帮助读者更感性地了解某人或某物而对该人或该物作出的外在相貌或内在特征的描写。例如The penguin is a kind of sea bird living in the South Pole. It is fat and walks in a funny way. Although it cannot fly，it can swim in the icy water to catch the fish.从例句的描述中可以得知penguin是一种生活在南极的鸟类.后面更详尽地描述了该鸟类的生活习性。
（二）外部相关因素
外部相关因素是指篇章（句子或段落）以外的其他知识，有时仅靠分析篇章内在逻辑关系无法猜出词义。这时，就需要运用生活经验和普通常识确定词义。例如：The snakes lithered through the grass.根据有关蛇的生活习性的知识，我们可以推断出slither词义为＂爬行＂。
（三）构词法
在阅读文章时，我们总会遇上一些新词汇，有时很难根据上下文来推断其词意，而它们对文章的理解又有着举足轻重的作用，此时，如掌握了一些常用的词根,前缀,后缀,合成等构词法知识，这些问题便不难解决了。
1.根据前缀猜测词义
例如：He fell into a ditch and lay there，semi-conscious，for a few minutes.根据词根conscious（清醒的，有意识的），结合前缀semi（半，部分的，不完全的），我们便可猜出semiconscious词义＂半清醒的，半昏迷的。＂I’m illiterate about such things.词根lit-erate意为＂有文化修养的，通晓的＂，前缀il表示否定，因此illiterate指＂一窍不通，不知道的＂。
2.根据后缀猜测词义
例如：Insecticide is applied where it is needed.后缀cide表示＂杀者，杀灭剂＂，结合大家熟悉的词根insect（昆虫），不难猜出insecticide意为＂杀虫剂＂。Then the vapor may change into droplets.后缀let表示＂小的＂，词根drop指＂滴，滴状物＂。将两个意思结合起来，便可推断出droplet词义＂小滴，微滴＂。
3.根据复合词的各部分猜测词义
例如：Growing economic problems were high-lighted by a slowdown in oil output. Hightlight或许是一个生词，但是分析该词结构后，就能推测出其含义。它是由high（高的，强的）和light（光线）两部分组成，合在一起便是＂以强光照射，使突出＂的意思。Bullfight is very popular in Spain. Bull（公牛）和fight（打，搏斗）结合在一起，指一种在西班牙颇为流行的体育运动—斗牛。
二、主旨大意类题型
主旨大意类题型主要测试学生对文章全面理解和概括的能力，提问的内容可能是全文的大意，也可能是某段的段落大意，一般不易在文中直接找到答案。怎样把握主旨大意题呢？通常有以下几种方法：
（一）阅读文章的标题或副标题
文章的标题是一篇文章的题眼，通过阅读标题或副标题可以迅速把握文章的主旨大意。
（二）寻找文章的主题句
分析篇章结构，找出文章主题。在许多情况下，尤其在阅读说明文和议论文时，根据其篇章特点我们可以通过仔细阅读短文的第一句或第二句,即文章的主题句来归纳出文章的主题.若短文由若干段组成，除仔细阅读第一段的首句外，还须仔细阅读每一段的第一句，即段落中心.通常文章的中心思想包含在文章的首句，有时也在文章的末句，其他句子都是用来说明和阐述主题句。因此，在确定文章的中心思想时，要求学生重视阅读文章的首句和末句。但也有一些文章，中心思想常常贯穿在全文中，因此要求学生综观全文，对段落的内容要融会贯通，对文章透彻理解后归纳总结。主题句的特点是：1.相对于其他句子，它表达的意思比较概括；2.主题句一般结构简单；3.段落中其他句子必定是用来解释,支撑或发展主题句所表达的思想的。
总之，为提高阅读理解能力，在阅读时应抓中心思想,作者意图及关键词语，运用联想、比较、归纳、推测等方法，得出最佳结论，选择最佳答案，不能主观臆测，把自己的观点强加进去，与文章的观点混为一谈。经过长时间有计划,有目的的系统训练，使学生加快阅读速度，提高阅读的正确性，使两者有机地统一起来，以提高学生阅读英语和运用英语进行交际的能力，为继续学习和运用英语切实打好基础.阅读是一种综合性很强的语言实际活动。我们只有进行大量的课内外阅读，掌握一定的阅读技巧，正确运用阅读方法，才能有效地提高阅读理解能力。

题组一（2020年高考真题）
Passage1(2020·全国新课标卷I，C)
Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
28．Why are race walkers conditioned athletes?
A．They must run long distances.
B．They are qualified for the marathon.
C．They have to follow special rules.
D．They are good at swinging their legs.
29．What advantage does race walking have over running?
A．It’s more popular at the Olympics.
B．It’s less challenging physically.
C．It’s more effective in body building.
D．It’s less likely to cause knee injuries.
30．What is Dr. Norberg’s suggestion for someone trying race walking?
A．Getting experts’ opinions.
B．Having a medical checkup.
C．Hiring an experienced coach.
D．Doing regular exercises.
31．Which word best describes the author’s attitude to race walking?
A．Skeptical. B．Objective.
C．Tolerant. D．Conservative.
Passage2(2020·全国新课标卷II，B)
Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills.
Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income, education and the amount of parent talk, Levine said.
The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age.
“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.
The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.
The findings were published in the journal Developmental Science.
24．In which aspect do children benefit from puzzle play?
A．Building confidence. B．Developing spatial skills.
C．Learning self-control. D．Gaining high-tech knowledge.
25．What did Levine take into consideration when designing her experiment？
A．Parents’ age. B．Children’s imagination.
C．Parents’ education. D．Child-parent relationship.
26．How do boy differ from girls in puzzle play?
A．They play with puzzles more often.
B．They tend to talk less during the game.
C．They prefer to use more spatial language.
D．They are likely to play with tougher puzzles.
27．What is the text mainly about?
A．A mathematical method. B．A scientific study.
C．A woman psychologist D．A teaching program.
Passage3(2020·全国新课标卷III，D)
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
Passage4(2020·全国山东新高考卷I，D)
According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
12．What is the recent study mainly about?
A．Food safety. B．Movie viewership.
C．Consumer demand. D．Eating behavior.
13．What does the underlined word “beanpoles” in paragraph 1 refer to?
A．Big eaters. B．Overweight persons.
C．Picky eaters. D．Tall thin persons.
14．Why did the researchers hire the actor?
A．To see how she would affect the participants.
B．To test if the participants could recognize her.
C．To find out what she would do in the two tests.
D．To study why she could keep her weight down.
15．On what basis do we “adjust the influence” according to the last paragraph?
A．How hungry we are. B．How slim we want to be.
C．How we perceive others. D．How we feel about the food.
题组二（2019年高考真题）
Passage1(2019·全国新课标卷I，C)
As data and identity theft becomes more and more common, the market is growing for biometric(生物测量)technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device(装置)that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏)with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.
It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
28. Why do the researchers develop the smart keyboard?
A. To reduce pressure on keys. B. To improve accuracy in typing
C. To replace the password system. D. To cut the cost of e-space protection.
29. What makes the invention of the smart keyboard possible？
A. Computers are much easier to operate.
B. Fingerprint scanning techniques develop fast.
C. Typing patterns vary from person to person.
D. Data security measures are guaranteed.
30. What do the researchers expect of the smart keyboard？all 1o soisgitieoco oll.
A. It'll be environment-friendly. B. It'll reach consumers soon.
C. It'll be made of plastics. D. It'll help speed up typing.
31. Where is this text most likely from?
A. A diary. B. A guidebook C. A novel. D. A magazine.
Passage2(2019·全国新课标卷I，D)
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
Passage3(2019·全国新课标卷II，D)
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.
Passage4(2019·全国新课标卷I，D)
Before the 1830smost newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.
The trend, then, was toward the "penny paper"-a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.
This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830,but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny-usually two or three cents was charged-and some of the older well-known papers charged five or six cents. But the phrase "penny paper " caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.
This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.
28. Which of the following best describes newspapers in America before the 1830s?
A. Academic. B. Unattractive. C. Inexpensive. D. Confidential.
29. What did street sales mean to newspapers?
A. They would be priced higher. B. They would disappear from cities.
C. They could have more readers. D. They could regain public trust.
30. Who were the newspapers of the new trend targeted at?
A. Local politicians. B. Common people.
C. Young publishers. D. Rich businessmen.
31. What can we say about the birth of the penny paper?
A. It was a difficult process. B. It was a temporary success.
C. It was a robbery of the poor. D. It was a disaster for printers.
题组三（2018年高考真题）
Passage1(2018·全国新课标卷I，D)
We may think we’re a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn’t throw out our old ones. “The living-room television is replaced and gets planted in the kids’ room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We’re not just keeping these old devices – we continue to use them. According to the analysis of Babbitt’s team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.
So what’s the solution (解决方案)? The team’s data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
32. What does the author think of new devices?
A. They are environment-friendly. B. They are no better than the old.
C. They cost more to use at home. D. They go out of style quickly.
33. Why did Babbitt’s team conduct the research?
A. To reduce the cost of minerals.
B. To test the life cycle of a product.
C. To update consumers on new technology.
D. To find out electricity consumption of the devices.
34. Which of the following uses the least energy?
A. The box-set TV. B. The tablet. C. The LCD TV. D. The desktop computer.
35. What does the text suggest people do about old electronic devices?
A. Stop using them. B. Take them apart.
C. Upgrade them. D. Recycle them.

Passage3(2018·全国新课标卷II，B)
Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.
Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.
When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.
If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
24. What does the author seem to like about cherries?
A. They contain protein. B. They are high in vitamin A.
C. They have a pleasant taste. D. They are rich in antioxidants.

题组四（名校模拟题）
Passage 1
（2020·河北衡水中学高三一模） Pigeons in London have a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.
“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is, and how it actually affects their health.” London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing(引用)a report released by the city manager last year. If people were better informed about the pollution they’ re breathing, she says, they could pressure the government to do something about it.
Nearby, on a windy hill in London’s Regent’s Park, an experiment is underway that could help—the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, from France, chose the problem of air pollution.
“Basically, I realized how important the problem was,” he says. “But also I realized that most of the people around me didn’t know anything about it.” Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.
“So”, he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones were his first thought. But it’s illegal to fly them over London. “But pigeons can fly above London, right?” he says. “They live—actually, they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low.”
So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city’s air.
5．What can we infer about London’s air quality from Paragraph 2?
A．Londoners are very satisfied with it.
B．The government is trying to improve it.
C．Londoners should pay more attention to it.
D．The government has done a lot to improve it.
6．Duquesnoy attended the London Design Festival to _________.
A．entertain Londoners. B．solve a world problem.
C．design a product for sale. D．protect animals like pigeons.
7．Why did Duquesnoy give up using drones to fly across London?
A．Because they are too expensive. B．Because they fly too quickly.
C．Because they are forbidden. D．Because they fly too high.
8．Which can be the best title for the text?
A．Clean air in London. B．London’s dirty secret.
C．London’s new pollution fighter. D．Causes of air pollution in London.
Passage2
（2020·天津耀华中学高三一模） A remote control is seemingly capable of invisible magic to most of us. We just assume it should. And the longer a given technology exits, the more we take it for granted.
Consider for a moment a split screen showing modem remote control users versus the first remote control users: the original users would be carefully aiming the remote directly at the television, reading the names of the buttons to find the right one, and intentionally pressing the button with a force that adds nothing to the effectiveness of the device. The modern users would be leaning on a sofa, pointing the remote any which way instinctively （本能的）feeling for the button they desired, intuiting（凭直觉知道）its size,shape, and position on the remote.
Humans are known for being handy with tools, so it is no surprise that we get so comfortable with our technology. However, as we become increasingly comfortable with how to use new technologies, we become less aware of how they work. Most people who use modern technology know nothing of its underlying science. They have spent neither mental nor financial resources on its development. And yet, rather than be humbled（使谦逊）by its originality, we consumers often become unfairly demanding of what our technology Should do for us.
Many of the landmark inventions of the twentieth century followed predictable tracks: initial versions of each technology (television, video games, computers, cell phones, etc.) succeeded in impressing the general public. Then, these wonderful new inventions quickly became commonplace. Soon, the focus of consumer attitudes towards them changed from gratitude with respect to discriminating preference.
Televisions needed to be bigger and have a higher resolution. Video games needed to be more realistic. Computers needed to be more powerful yet smaller in size. Cell phones needed to be smaller yet capable of performing other tasks such as taking pictures, accessing the Internet, and even playing movies.
For children of the last twenty years born into this modern life, these technological marvels seem like elements of the periodic table: a given ingredient that is simply part of the universe. Younger generations don't even try to imagine life without modem conveniences. They do not appreciate the unprecedented（史无前例的）technology that is in their possession; rather, they complain about the ways in which it fails to live up to ideal expectations. “My digital video recorder at home doesn't allow me to program it from my computer at work.” “It's taking too long for this interactive map to display on my portable GPS”.
If it sounds as though we're never satisfied, we aren't. Of course, our complaints do actually motivate engineers to continually refine their products. After all. at the root of our tool-making instinct is the notion (观念）that “there must be a better way.” Thus, the shortcomings of any current version of technology are pinned on the limitations of its designers, and the expectation is that someone, somewhere is working on how to make the existing product even better.
35．The second paragraph is used to suggest that______________.
A．modem humans do not pay enough attention to instructions
B．remote controls have become far more effective over the years
C．consumer behavior toward new forms of technology changes over time
D．the first consumers of new technology used new devices with ease and comfort
36．The passage states that original users of remote controls likely__________.
A．have no instinctive feeling for sizes and shapes
B．press the buttons harder than it is necessary
C．don't trust on the effectiveness of remote control
D．have difficulty reading the names of the buttons
37．Which of the following can illustrate people's discriminating preference?
A．People take a given technology for granted.
B．Consumers expect more powerful computers.
C．Children lack patience with the shortcomings of technology.
D．Original users unfairly demand of what technology should do.
38．What does the underlined statement in paragraph 6 probably mean?
A．Space exploration provides us with new technology.
B．Adults learn technology while they are doing household chores.
C．High expectation makes up for the limitation of technology designers.
D．Consumers regard many technological inventions as unremarkable
39．The writer thinks the way people consider technology____________.
A．encourage designers' creativity B．limit humans’ productivity
C．raise consumers' expectation D．guarantee users' satisfaction
Passage3
2020·江苏江都高三二模） Sweet potato plants don't have spines or poisons to defend themselves. But some have evolved a clever way to let hungry herbivores (食草动物) know they aren't an all-you-can-eat buffet, a new study finds. When one leaf injured, it produces a chemical that warms the rest of the plant and its neighbors to make themselves inedible (不宜食用的)to bugs. Sweet potato breeders could potentially engineer plants to produce the chemical as an all-natural pest defense.
Plant ecologists led by Axel Mithofer of the Max Planck Institute for Chemical Ecology in Jena, Germany, started to look into sweet potato (Ipomoea batatas) defenses after they noticed something interesting about two varieties of the plant grown in Taiwan: The yellow-skinned, yellow-fleshed Tainong 57 is generally herbivore-resistant, but its darker orange cousin, Tainong 66, is plagued (造成麻烦) by insect pests.
To find out why, the team offered up Tainong 57 and 66 plants to hungry African cotton leafworm caterpillars (毛虫).Both plants released at least 40 airborne compounds as the caterpillars snacked on their leaves. But Tainong 57 produced a lot more of a chemical called DMNT, which has a very distinct smell, the team details this month in Scientific Reports. (“The smell is not nice,” Mithofer says. “You wouldn't want it as a perfume.”)
DMNT isn't a new compound; researchers have isolated (分离出) the smelly chemical from other plants such as corn and cabbage, and it is known to induce defense responses in some species.
To determine whether this was happening in sweet potatoes, scientists set up two experiments. First, they put two plants next to each other and wounded one so it produced DMNT. Then, they exposed healthy Tainong 57 plants to DMNT they had synthesized (合成).In both cases, the DMNT caused the exposed plants to produce more of a protein called sporamin in their leaves. (Tainong 66 did not have the same reaction.) When the caterpillar’s snack on sporamin, “they immediately stop eating because they don't feel well,” Mithofer says.
Sporamin is the main protein in sweet potato tubers (块茎),and is indigestible raw, which is why sweet potatoes must be cooked for humans to enjoy them. “If the caterpillars could cook it, they could eat it,” Mithofer says. Theoretically, he says, sweet potato breeders could use genetic engineering to make different varieties of sweet potato produce as much DMNT as Tainong 57, and display the same defense responses.
Still, the research isn't ready for prime time, cautions plant ecologist Martin Heil. DMNT might work in the lab, but in the field, airborne chemicals can be “blown away in seconds,” says Heil, who studies plant-insect interactions at the National Polytechnic Institute in Irapuato, Mexico.
Mithofer himself has no plans now to create genetically engineered sweet potato plants, because they would not be a viable (能活下去的) crop in Europe, where genetically modified crops are outlawed. So for now, Tainong 66 will have to put up with being a caterpillar salad bar.
1．What is the purpose of the experiment carried out by Axel's team?
A．To find out why DMNT has a very distinct smell.
B．To determine which sweet potato suits caterpillars better.
C．To find out why Tainong 57 resists bugs while Tainong 66 doesn't.
D．To determine what compounds are released when bugs eat sweet potatoes.
2．Which is an example of the underlined words “defense response” in Paragraph 4?
A．Researcher isolated the smelly chemical from plants.
B．Corn produces a chemical to avoid being eaten by bugs.
C．Two plants are put next to each other for an experiment.
D．Caterpillars have stomach trouble when they snack on sporamin.
3．The tone of the this passage can be described as .
A．humorous B．serious C．causal D．subjective
4．What's the author's attitude towards GM Tainong 66?
A．Supportive. B．Objective. C．Opposed. D．Skeptical.
Passage 4
（2020·山西大同高三月考） The new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.
The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste.
Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.
Household food waste, which is translated to “wet trash” in Chinese，refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.
Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.
The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.
As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.
“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste.” The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.
1．What do the old thrown-away sweaters belong to?
A．Residual waste. B．Hazardous waste.
C．Recyclable waste. D．Household food waste.
2．What does “wet trash” have in common?
A．They are completely wet. B．They all come from plants.
C．They can give off bad smell. D．They can break up easily.
3．What is the tone of the netizen?
A．Humorous. B．Serious.
C．Delightful. D．Uncertain.
4．What is the main idea of the text?
A．Shanghai bans four sorts of garbage.
B．Shanghai launches garbage sorting enforcement.
C．Citizens in Shanghai still question garbage sorting.
D．Citizens in Shanghai welcome the garbage sorting policy.
