一、高中英语阅读理解科普环保类
1．犇犇阅读短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.
A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.
According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.
The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans. "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."
（1）What has become a concern about robots?
A. How to humanize them.
B. How to treat them in life.
C. How to use them effectively.
D. How to find more applications.
（2）In the study the participants probably have to decide ________.
A. when to sacrifice a robot
B. where to experience risks
C. which robot to work with
D. what robots should be like
（3）What can be inferred from Paulus' words?
A. Humanized robots offer less help to people.
B. Humanizing robots too much may be improper.
C. Certain moral status should be attached to robots.
D. Conflicts often happen between humans and robots.
（4）Which of the following would be the best title for the text?
A. Robots, A Must for Future
B. Humanized Robots, A New Trend
C. Robot Saved, People Take the Hit
D. Humanized Robots, Replace Human
【答案】（1）B
（2）A
（3）B
（4）C

2．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

A team of international scientists is due to set off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.
Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say
it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission.
"The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undersea environment changes as sunlight enters the water."
Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one. Larsen C is a long way south and there's lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die."
There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate, the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.
（1）Why are the scientists eager to go to the iceberg?
A. To study how the iceberg was formed.
B. To study a newly discovered ecosystem.
C. To explore a new way to prevent climate change.
D. To explore the geography of the Larsen C ice shelf.
（2）What do the underlined words "this one" in the fourth paragraph refer to?
A. The Larsen C ice shelf.
B. Climate change in Antarctica.
C. The A68 iceberg with the ecosystem beneath it.
D. The condition of animal species in Antarctica.
（3）What can we learn about the A68 iceberg from the text?
A. It is as big as London.
B. It is part of an ice shelf in the Arctic.
C. It will disappear in a very short time.
D. It has uncovered an unknown ecosystem in Antarctica.
（4）What can we infer from the last paragraph?
A. There is no need to worry about climate change in Antarctica.
B. The ice sheets in Greenland and Antarctica are melting at a steady rate.
C. Many creatures living in deep water will die out due to climate change.
D. By 2100, the sea level will have risen to a much higher level than now.
【答案】（1）B
（2）C
（3）D
（4）D

3．犇犇阅读理解
The Alexander technique
Until earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.
The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.
The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any
inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.
So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.
So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.
（1）What does the author suggest in Paragraph 1?
A. She felt no better after the treatment.
B. She got bored with the Alexander technique.
C. She was sceptical about the doctor's method.
D. She was unwilling to seek treatment for her backache.
（2）What is the principle of the Alexander technique?
A. Physical tension shouldn't be completely relieved.
B. The technique shouldn't be combined with other exercises.
C. The practice of the technique shouldn't be attempted alone.
D. Familiar physical actions shouldn't be done with much effort.
（3）What can we learn about Frederick Alexander?
A. He managed to recover his vocal powers.
B. He was eager to make a name for himself.
C. He developed a form of exercise for actors.
D. He had to leave home to develop his technique.
（4）What is the main idea of the passage?
A. The occurrence of back pain is widespread.
B. Alexander improved the technique to treat body pain.
C. The Alexander technique helps overcome posture problems.
D. People with back pain are victims of inappropriate postures.
【答案】（1）D

4．犇犇阅读理解
Wolves strike fear into the hearts of many species, humans included. Our fear of them has brought them to the edge of dying out, as we have cruelly killed them as competitors and trouble-makers. But researchers are discovering that the very fear they put into prey（被捕食者）species is exactly what helps make ecosystems（生态）healthy.
Yellowstone National Park is a typical example of just how wolves can help repair an ecosystem. An October 2018 study analyzed 40 years of research on large animals inside the park.
"Yellowstone has benefited from the reintroduction of wolves in ways that we did not anticipate, especially the complexity of biological interactions（互动）in the park," explained Mark Boyce, a professor in the Department of Biological Sciences." We were really surprised at that and we'd never have seen these responses if the park hadn't adopted ecological-process management—allowing natural ecological processes to take place with least human intervention."
After the wolves were re-introduced at Yellowstone, willow and cottonwood trees increased in number. The population of bears and bison also rose and what was once a ruling deer-wolf interaction is now more diverse.
To learn more about just how wolves are beneficial, a short documentary from Quest explains how the presence of wolves influences the behavior of deer, which eventually makes entire ecosystems more biologically diverse and healthy. In this documentary, biologist Aaron Wirsing explored why wolves and other top predators （捕食者）were needed for diverse ecosystems to develop. Using a simple video camera, Wirsing is gaining a unique view point on predator-prey relationships and changing the way we think about wolves.
The research is one more piece of evidence for why protecting these top predators is important not just for wolves as a species, but for hundreds of species at every level of an ecosystem. The fear they bring along may be the very angle that helps save them from dying out.
（1）What does the underlined word "anticipate" in paragraph 3 probably mean?
A. Expect.
B. Understand.
C. Notice.
D. Accept.
（2）For what purpose was a documentary made?
A. To introduce how wolves behave in the wild.
B. To show how wolves benefit from ecosystems.
C. To record how Aaron Wirsing observed wolves.
D. To study what good wolves can do to ecosystems.
（3）What is the significance of the research?
A. It proves wolves feed on hundreds of species.
B. It helps prove the importance of protecting wolves.
C. It shows the complex relationships between species.
D. It provides evidence that wolves are endangered animals.
（4）What is the main idea of the passage?
A. The fear of wolves is beneficial to ecosystems.
B. The fear of wolves put them in danger of disappearing.
C. Yellowstone National Park owes its healthy ecosystems to wolves.
D. The introduction of wolves in Yellowstone National Park is a success.
【答案】（1）A

5．阅读理解
A new study suggests a link between exposure to greenery and reduced desires for alcohol cigarette and junk food.
The study is the first to investigate the possible relationships between exposure to nature and desires and negative emotions. Researchers at the University of Plymouth's School of Psychology surveyed 149 respondents (应答者) aged 21 o 65 about the proportion( 比例 )of green space in their neighborhood, the presence of green views from their home, their access to a garden and how often they use public green space. The study also asked questions about experiences with depression and anxiety, as well as desires for things like caffeine, alcohol and nicotine. Participants rated the intensity( 强度), imagery, and intrusiveness(侵扰性) of their desires on an 11-point scale.
Researchers found the presence of visible green space contributed to decreased desires for junk food. The effect was particularly noticeable when more than 25 percent of a respondent's view was greenery.
Previous scholarship(学术研究) has dealt mostly with exercise in nature: A 2015 study out of the University of Michigan found 90- minute group nature walks were effective at combatting depression and relieving other mood disorders. But for people who struggle with accessibility or don't have time for a 90-minute walk, this new study suggests just looking out a window at a tree can help fight off a bad habit.
"It has been known for some time that being outdoors in nature is linked to a person's well-being," lead author Leanne Martin said in a statement." But for there to be a similar association with desires from simply being able to see green space adds a new dimension to the previous research."
A 2018 study from Denmark's Aarhus University for example, found that. Having access to green space throughout childhood decreased a person's risk of developing mental health problems as an adult.
（1）What does the second paragraph mainly talk about?
A.The results of the new study.
B.The purpose of the new study.
C.The significance of the new study.
D.The content of the new study.
（2）What does the underlined word "combatting" in paragraph 4 probably mean?
A.Reducing.
B.Developing.
C.Understanding.
D.Encouraging
（3）According to the passage, the new study _____.
A.mainly referred to exercise in nature
B.has enriched the previous research to some degree
C.was carried out by the University of Michigan
D.found exposure to greenery helped cure mental problems
（4）n which section of a newspaper may this passage appear?
A.Entertainment
B.Business World
C.Tech &Science
D.Environment
【答案】（1）D
（2）A
（3）B
（4）C
【解析】【分析】本文是一篇说明文，介绍了一项新的研究成果---多看绿色植物和吃垃圾食品这两者看似风马牛不相及，可研究结构却表明它们之间存在着一种奇妙的关系：多看绿色植物能帮助人们克制吃垃圾食品的欲望。

6．阅读理解
Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as heat to make the ice on the windshield disappear.
According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.
Solar energy is only available about half the time we need it — during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey
Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun's energy through a chemical reaction and releasing it later as heat.
The key to enabling long-term, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (触发)by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.
Such chemically-based storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solid-state films. The new approach is the first based on a solid-state material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.
（1）What is the main purpose of Paragraph 1?
A.To show the main idea of the passage.
B.To practice readers' imagination.
C.To interest readers in the passage.
D.To introduce a new kind of material.
（2）According to the passage, what can the polymer film do?
A.It can be made into window glass.
B.It can make necessary electricity.
C.It can store energy and release sunshine.
D.It can absorb sunshine and give off heat.
（3）According to the passage, what is STF based on?
A.The chemical reaction.
B.The movement of heat.
C.The form of electricity.
D.The physical reaction.
（4）What is the advantage of the molecular configuration?
A.It is less expensive.
B.It is very powerful.
C.It is easily available.
D.It is less changeable.

7．阅读理解
Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean - energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.
Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306 - 521) per MWh of electricity by 2025, compared with ￡58 - 75 for seagoing wind turbines (轮机) and ￡55 - 76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.
An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).
But there would be nothing old - fashioned about Mr Rainey's wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.
（1）What is special about the mouth of the River Seven?
A. The tidal range there is about 15 meters.
B. It has the largest tidal range in the world.
C. The tidal power station has been built there.
D. Its power plant makes life harder for wildlife.
（2）What was people's initial attitude towards tidal power?
A.Opposed.
B.Supportive.
C.Controversial.
D.Doubtful.
（3）What are the locks used for?
A.Support.
B.Transportation.
C.Securing wheels.
D.Producing electricity.
（4）What's the best tittle for the text?
A.Rainey invented turbines.
B.Rainey's tidal power station.
C.Tidal power in the River Seven.
D.An old idea might be made practical.
【答案】（1）A
（2）A
（3）B
（4）D
