(2020·郑州质量预测)Four teenage girls from Minnesota, US. 120 hours of nonstop togetherness. No cellphones. This is not a reality show, but an adventure journey.
“It was really perfect，” said Julia Ruelle of her recent adventure to the Boundary Waters Canoe Area Wilderness with three of her childhood friends. “By unplugging, we had an amazing time.”
Last year, the 16­year­old took part in an essay contest and carried off a prize. The award was a 5­day canoe and camping adventure with up to three friends. No parents or guides would be there. So Julia invited her friends Anna Wander, Madeline Wilson and Julianna Torelli.
The four Minnetonka High School juniors arrived in Ely for training the day before they began the journey. They set out the next day at 7 a．m., quickly developing a routine.
“We were done paddling by noon，” Julia said. “We ate lunch at the campsites and then it was time for hammocks(吊床), reading, making friendship bracelets(手镯) and talking.”
The girls all had experience in the outdoors before.
Anna had been to the Boundary Waters with her family. “I love how you are separated from everything in your life, especially technology, ” Anna said. Without her phone, she said, “I’m less worried about things.” Madeline, too, had been to the Boundary Waters a few years ago. “But this time, I had to paddle right and set up camp，” she said. The girls made fire and cooked meal together. No one was ever hungry or homesick, but they were nervous in the final night as they waited out a thunderstorm. They left wet sleeping bags in one tent, and squeezed into another for the night. “Every thunderstorm in the Boundary Waters feels huge，” Julia said.
On the car ride home, they were all on their phones catching up with friends. “It was a little at a loss turning my phone on，” said Anna. “Mental health can be improved so much in the Boundary Waters. It really helps to get away and reconnect with yourself.”

A．They needed to complete many tasks.
B．They needed to find a guide on their own.
C．They had to live on a boat for several days.
D．They had to live without their smartphones.

(2020·河南六市高三联考)It was about seven years ago. I just picked up my three­year­old daughter from the nursery. I was weighed down with shopping bags, and with my daughter’s things. We arrived at a pedestrian crossing and she pressed the button. In the distance, I heard alarms, told my daughter to wait and watched a police car approaching.
Little did I know, as the__green__man flashed, that my daughter had begun to run into the road. I watched the police car speed toward us—that’s when you sounded your horn and waved wildly to me. My daughter was about a meter from the path of the police car, hidden from their view by your car.
I screamed her name and ran toward her. She stopped and was shocked by the rush of the police car as it sped past. She wondered why you had blown your horn, asking, “Mom, why was that woman so rude？” not realizing you had saved her life.
She wondered why I picked her up and burst into tears. My legs gave way as I reached the other side of the road. I should have followed my “wait” with a hand on her shoulder, or an explanation of why we were ignoring the green man this time, especially as I had in effect conditioned her to cross the road at the sight of the green flash.
I beat myself up for months, and still do, with flashbacks and horrible assumptions about what might have been. But for your sounding your horn, seeing what I hadn’t seen, I would have been left a mother on the other side of the road, totally broken. I apologize for putting you in that position—I can imagine that it upset you，too. You saved her life and I am so grateful.
【解题导语】　本文是一篇记叙文。大约七年前，“我”的女儿过马路时没有注意到警车，幸亏一位女士按喇叭提醒，才挽救了女儿的生命。这件事让“我”至今难忘，心中充满感激。
4．What does the underlined part “the green man” in Paragraph 2 refer to?
A．A pedestrian.　 B．A policeman.
C．A traffic sign. D．A button.

5．Why did the woman sound her horn?
A．To stop the police car.
B．To show her impatience.
C．To greet passing pedestrians.
D．To draw the mother’s attention.
D　解析：推理判断题。根据第二段第二、三句“I watched the police car speed toward us—that’s when you sounded your horn and waved wildly to me. My daughter was about a meter from the path of the police car, hidden from their view by your car.”可知，“我”看到警车向“我们”疾驰而来，这时你按响了喇叭，疯狂地向“我”挥手。“我”的女儿离警车的车道大约一米远，你的车挡住了他们的视线。据此可推知，那位女士按响喇叭是为了引起这位母亲的注意，提醒她注意她女儿的安全，故D项正确。
6．What can we infer from the incident?
A．The mother didn’t regret what had happened.
B．The daughter didn’t follow the traffic rules.
C．The woman responded quickly and properly.
D．The police drove beyond the speed limit.
C　解析：推理判断题。根据第二段可知，当看到小女孩面临危险时，那位女士按响喇叭，并疯狂地向小女孩的母亲挥手；并结合第三段第一、二句“I screamed her name and ran toward her. She stopped and was shocked by the rush of the police car as it sped past.”可知，警车疾驰而过，“我”的女儿安然无恙；据此可推知，那位女士反应快速、正确，挽救了小女孩的生命，故C项正确。
7．How did the mother feel when taking hold of her daughter?
A．Angry and shocked.
B．Scared but relieved.
C．Guilty and confused.
D．Grateful but sad.
B　解析：推理判断题。根据第四段第一、二句“She wondered why I picked her up and burst into tears. My legs gave way as I reached the other side of the road.”可知，女儿不知道“我”为什么把她抱起来并突然大哭起来；当“我”走到路的另一边时，“我”的腿软了；结合上文可知，一位女士的提醒使“我”的女儿避免了车祸；据此可推知，抓住女儿时，这位母亲既害怕，又感到宽慰，故B项正确。

A
(2020·济南针对性训练)The Amazon basin region is home to about 2.5 million insect species, tens of thousands of plants, and some 2，000 birds and mammals. To date, at least 40，000 plant species, 3，000 fish, 1，294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. One in five of all the birds in the world live in the Amazon rainforest.
The warm and wet forest has been in existence for at least 55 million years, and thrived even during glacial periods, allowing for the evolution of an unbelievable diversity of species. Radiocarbon dating(放射性碳定年法) has revealed trees of 10 centimeter in diameter to be more than 300 years old, and some trees over 1，000 years old, indicating that untouched forests can experience unbelievable longevity.
The first human inhabitants are thought to have settled in the Amazon region about 11，200 years ago. European explorers arrived in the 16th century, bringing diseases which traveled faster than the explorers themselves, killing perhaps as many as 90% of the indigenous inhabitants(土著居民). By the late 17th century the Amazon basin was controlled by Portuguese and Spanish explorers.
The Amazon rainforests has been described as the lungs of our planet because of its important role in recycling carbon dioxide into oxygen. But due to deforestation(滥伐森林), rainforests now cover less than 5% of the Earth’s land surface, and experts believe that this is a big contributor to global climate change. Severe deforestation began in the 20th century, with 587，000 square kilometers lost up to the year 2000.Most deforested land is used for grassland to raise farm animals and agriculture. The addition of transport routes has led to increased settlement and deforestation, and at the present rate, scientists estimate that the Amazon rainforest will be reduced by 40% in two decades.
【解题导语】　本文主要讲述了亚马逊热带雨林的历史、丰富的物种以及现在所面临的危险。
1．Why are the figures mentioned in Paragraph 1?
A．To prove the forest untouched.
B．To classify species scientifically.
C．To show the diversity of species.
D．To attract more attention to the Amazon region.
C　解析：推理判断题。根据第一段的内容并结合第二段第一句中的“allowing for the evolution of an unbelievable diversity of species”可推知，那些关于动植物种类的数字说明了亚马逊热带雨林的物种多样性，故选C。
2．Why did most indigenous inhabitants in the Amazon region die?
A．European explorers brought diseases there.
B．Portuguese explorers treated them badly.
C．A lot of trees were cut down and burned.
D．They got killed by Spanish explorers.
A　解析：细节理解题。根据第三段第二句“European explorers arrived in the 16th century, bringing diseases which traveled faster than the explorers themselves, killing perhaps as many as 90% of the indigenous inhabitants(土著居民)．”可知，可能多达90%的亚马逊土著居民因为欧洲探险者所带来的疾病而死亡，故选A。
3．What can be inferred about the Amazon rainforest?
A．It has the largest number of species.
B．It covers over 5% of South America.
C．It is becoming larger in area.
D．It is being endangered now.
D　解析：推理判断题。根据最后一段尾句中的“at the present rate...in two decades”并结合最后一段的整体内容可推知，亚马逊热带雨林遭到破坏，而且未来20年可能会减少40%，故选D。
4．What may be included in the following paragraph?
A．Examples of destroying forests.
B．Measures to protect rainforests.
C．New settlements in the Amazon region.
D．Ways to stop global warming.
B　解析：推理判断题。根据最后一段的关键词“deforestation”可推知，亚马逊热带雨林砍伐严重，那么本文接下来自然就会论述这一问题的解决措施，故选B。

(2020·信阳高三调研)Plants cannot run or hide, so they need other strategies to avoid being eaten. Some curl up their leaves, others produce chemicals to make themselves taste bad if they sense animals drooling on them, chewing them up or laying eggs on them—all signals of an attack. New research now shows that some flora can feel a plant­eating animal well before it launches an attack, letting a plant prepare a preemptive(先发制人的) defense that even works against other pest species.
When ecologist John Orrock of the University of Wisconsin­Madison sprayed snail slime—a liquid the animals release as they slide along—onto soil, nearby tomato plants appeared to notice. They increased their levels of an enzyme(酶), which is known to prevent plant­eating animals. “None of the plants were ever actually attacked，” Orrock says. “We just gave them cues that suggested an attack was coming, and that was enough to cause big changes in their chemistry.”
Initially Orrock found this defense worked against snails; in the latest study, his team measured the slimy warning’s impact on another potential threat. The investigators found that hungry caterpillars(毛虫), which usually eat tomato leaves greedily, had no appetite for them after the plants were exposed to snail slime and activated their chemical resistance. This nonspecific defense may be a strategy that benefits the plants by further improving their overall possibilities of survival, says Orrock, who reported the results with his colleagues in March in Oecologia.
The finding that a snail’s approach can cause a plant response that affects a different animal made Richard Karban curious, a plant communications expert, who was not involved in the study. “It is significant that the plants are responding before being damaged and that these cues are having such far­ranging effects，” Karban says. “The research was comprehensive，” he adds, “but he wonders how the tomato plants felt chemicals in snail slime that never actually touched them.”
“That’s the million­dollar question，” Orrock says. He hopes future research will make out the mechanisms that enable plants to sense these relatively distant cues.
【解题导语】　本文主要介绍了一项新的科学研究。研究表明植物会对外在威胁相当警觉，会自动作出反应进行自我保护。
5．John Orrock sprayed a liquid onto soil near tomato plants to ________．
A．make them grow better
B．give them a warning
C．keep plant­eating animals away
D．inform plant­eating animals of danger
B　解析：推理判断题。根据第二段最后一句“We just gave them cues that suggested an attack was coming, and that was enough to cause big changes in their chemistry.”可推知，John Orrock在西红柿植株附近的泥土上喷洒液体的目的是给予植物一种警告，让它们能够产生自我保护性反应，且其与第三段第一句中的“his team measured the slimy warning’s impact on another potential threat”呼应，故选B。
6．Why is the example of caterpillars mentioned in Paragraph 3?
A．To introduce another animal.
B．To confirm the result of the study.
C．To appeal to people to protect animals.
D．To analyze different resistance chemicals.
B　解析：推理判断题。根据第三段第一句“Initially Orrock found this defense worked against snails；in the latest study, his team measured the slimy warning’s impact on another potential threat.”可推知，文章中提到毛虫的例子是为了验证研究的结果，故选B。
7．What does Richard Karban really want to know?
A．How tomato plants become aware of danger.
B．What the chemicals in the snail slime are.
C．Whether the research is of practical value.
D．What the finding of the research is.
A　解析：推理判断题。根据第四段最后一句“‘The research was comprehensive，’he adds，‘but he wonders how the tomato plants felt chemicals in snail slime that never actually touched them.’”，并结合对最后一段的整体理解可推知，Richard Karban实际上想了解的是西红柿植株是如何意识到危险的，故选A。
8．What can be a suitable title for the text?
A．Watchful Plants B．Greedy Animals
C．A Snail’s Approach D．A Defense Attack
A　解析：标题归纳题。根据文章中的关键词plant，并结合对全文的整体理解可推知，本文主要讲述的是有关植物的科学研究，研究发现植物有对外在威胁或攻击的自我保护性反应，故选A。

【解题导语】　本文主要介绍了英国正在流行的两大趋势，即素食主义和有机农业。
1．to eat　解析：考查非谓语动词。此处为固定搭配decide not to do sth.“决定不做某事”，故用不定式作宾语。
2．are becoming　解析：考查动词的时态和主谓一致。与上文“Vegetarianism(素食主义) is becoming one rising trend in the UK”呼应可知，此处用现在进行时，表示现在的一种趋势，且与句子主语的复数形式保持一致，故用are becoming。
3．Why　解析：考查疑问副词。与语境中的问号呼应，并结合下文的内容可推知，此处表示对原因的疑问，故用特殊疑问词Why。
4．on　解析：考查介词。effect on sb./sth.意为“对某人/某(事)物有影响”，为固定搭配，故用介词on。
5．Worries　解析：考查名词的单复数。worry为可数名词时，意为“令人担忧的事”，且根据语境及该句中的have可知，此处用名词的复数形式作主语。
6．healthier　解析：考查形容词的比较级。句意：为了变得更健康，其他一些人选择改变他们的饮食习惯。此处包含一个比较的概念，故用形容词比较级形式作become的表语。
7．the　解析：考查冠词。risk被介词短语of certain cancers修饰，表示特指，故用定冠词the修饰。
8．another　解析：考查限定词。与上文“Vegetarianism(素食主义) is becoming one rising trend in the UK”呼应可知，此处表示另外一种兴起的趋势，故用限定词another修饰名词trend，表示“再一，另一”。
9．organically　解析：考查副词。修饰动词用副词，故用副词organically修饰动词produced。
10．is produced　解析：考查动词的时态和语态。分析句子结构可知，produce与句子主语Organic meat是被动关系，且表示客观叙述，故用其一般现在时的被动语态形式。
