一、高中英语阅读理解科普环保类
1．犇犇阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand?
Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China's Huawei both launched foldable phones, the Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the "foldable future", The Verge noted.
The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they're "the combination of a small tablet and smartphone, all in a single device".
The technology could change other devices, too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to maximize available space.
In a keynote address, Samsung's senior vice president of mobile product marketing, Justin Denison, called the foldable screen "the foundation for the smartphone of tomorrow". "It's a blank canvas (画布) for us to do something beautiful together." he said.
So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of every 10 OLED (二极管) screens produced were imperfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That's a price that few people will be able to afford.
But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry analyst told The Verge, "Few are debating if foldable or rollable mobile displays are the future of smartphones; the only question is when and by whom."（1）What can be the best title for the text?
A. Screen devices on the market.
B. Foldable age is arriving.
C. Possible powers of a tablet.
D. Foldable screens are imperfect.
（2）What can we learn from Justin Denison's words?
A. The foldable screen has great potential.
B. The Galaxy Fold still has many problems.

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。

Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.
The findings contradict research published earlier this year showing that returning adult children trigger a significant decline in their parents' quality of life and wellbeing.
The young adults taking part in the study were "more positive than might have been expected about moving back home—the shame is reduced as so many of their peers are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often slipping back easily into teenage patterns of behaviour, the study found.
Parents on the whole were more uncertain, expressing concern about the likely duration of the arrangement and how to manage it. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.
The families featured in the study were middle-class and tended to view the achievement of adult independence for their children as a "family project". Parents accepted that their children required support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out and get on the housing ladder. "However", the study says, "day-to-day tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates".
Areas of disagreement included chores, money and social life. While parents were keen to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.
（1）What is the finding of the previous research?
A. Boomerang children made their parents happier.
B. The parents were looking forward to their children's return.
C. The parents' quality of life became worse than before.
D. Boomerang children never did any housework.
（2）The underlined word "trigger" in Paragraph 2 may be best replaced by ________. A. cause B. defeat C. arise D. allow
（3）What is the attitude of the college graduates towards returning home?
A. They are ashamed of turning to their parents for help.
B. They are glad that they could come back.
C. They are doubtful about whether they should return.
D. They are proud to be independent from the family.
（4）What can be inferred as the reason for the "boomerang children" phenomenon? A. The children want to keep in closer touch with their parents.
B. The parents are willing to provide support to their children.
C. It is harder for the children to secure a satisfying job.
D. There is more house work needed to be done by the children.
（5）What is the side effect of the boomerang children phenomenon?
A. Both parents and children enjoy a more harmonious relationship.
B. Neither parents nor children want to do the chores at home.
C. Not only parents but also children want to be independent.
D. There are occasional quarrels between parents and children.
【答案】（1）C
（2）A
（3）B
（4）C
（5）D
【解析】【分析】本文是一篇说明文，一项研究发现，“回巢族”子女在大学毕业后回到父母身边生活对家庭是有好处的，他们会与父母建立更亲密、更具支持性的关系，并增进两代人之间的联系。

而这一发现与今年早些时候发表的一项研究结果相矛盾，该研究显示，返乡的成年子女会导致父母的生活质量和幸福感显著下降。

父母和孩子对于独立的紧张情绪会导致父母和子女之间偶尔的争吵。

（1）考查推理判断。

根据第二段中的“The findings disagree with the research published earlier this year showing that returning adult children trigger a significant worsening in their parents' quality of life and wellbeing.”这一发现与今年早些时候发表的一项研究结果不一致，早些的研究显示，返乡的成年子女会导致父母的生活质量和幸福感显著恶化。

可知，以往的研究显示，返乡的成年子女会导致父母的生活质量和幸福感比之前更差，故选C。

（2）考查词义猜测。

根据第二段中的“The findings disagree with the r esearch published earlier this year showing that returning adult children trigger a significant worsening in their parents' quality of life and wellbeing. ”通过新旧研究对比，以往的研究表明，返乡的成年子女会导致父母的生活质量和幸福感显著下降。

即可推理划线部分单词trigger意为“导致，致使”，与cause意义一致。

故选A。

（3）考查细节理解。

根据第三段中的“The young adults taking part in the study were‘more positive than might have been expected’about moving back home – the shame is reduced as so many of their friends are in the same position, and they acknowledged the benefits of their parents' financi al and emotional support.”参与这项研究的年轻人对于搬回家“比预期的更积极”——他们的羞愧感减少了，因为他们的许多朋友都处于同样的处境，而且他们承认父母在经济和情感上的支持是有好处的。

）可知，大学毕业生对回家的态度是积极的，很高兴能够回家，故选B。

（4）考查推理判断。

根据第四段中的“But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.”但他们承认，如今的毕业生情况有所不同，他们毕业时背负着巨额债务，工作机会也更少。

由此推断出，孩子们很难找到一份满意的工作，故选C。

（5）考查细节理解。

根据倒数第二段中的"‘However’, the study says, ‘day-to-day tensions
about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict”可知对于实现不同层面独立前景的日常紧张情绪，是大多数家长和略多于一半毕业生经历的特征。

在少数极端情况下，这种紧张情绪接近冲突。

可知回巢族孩子现象的副作用是在少数情况下，紧张情绪会导致父母和孩子之间偶尔发生争吵。

故选D。

【点评】本题考点涉及细节理解，词义猜测和推理判断三个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。

3．犇犇阅读理解
A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.
Shining iridescent color, which changes depending on the angle from which it's viewed, is favored by everything from birds to beetles and blossoms to butterflies.
"And in our research group we are of course interested in why this vivid metallic color is so widespread in nature." Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. " Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates." But iridescence also shows up in situations where reproduction is not an issue. " So what we are studying now is whether natural selection imposed by predation(捕食行为) could explain the occurrence of iridescence in prey animals."
The idea that eye-catching colors could be used as a cover-up isn't a new one." The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing-Coloration in the Animal Kingdom, already in 1909, that 'brilliantly changeable or metallic colors are among the strongest factors in an animal's concealment'. And this sounds like a completely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal's concealment？"
"In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition." Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. "It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish." As for making use of this method for hiding in plain sight, "Any practical applications is of course directly linked to any industry that
has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize." The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird's-eye view.
（1）According to the passage, iridescence is not made use of by animals to ________. A. live a little longer by escaping their predator(捕食者) B. catch the attention of their mates C. conceal themselves when in danger D. catch sight of more colorful preys （2）From the study in the last paragraph, we can learn that ________.
A. Bees can always tell the difference between a circle and an oval
B. Bees are creatures that are fascinated by sweet things that are iridescent
C. If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding it
D. Bees are likely to prefer circles to ovals, whether they are iridescent or not
（3）What will be talked about in the following paragraph?
A. Whether there are any differences between bees and birds.
B. Some industries that have great interest in camouflage.
C. Why birds are not effected by iridescent insects.
D. Which camouflage theory applies more to birds.
（4）Which of the following might serve as the best title of the passage?
A. A famous camouflage strategy
B. Metallic iridescent as the best disguise
C. Colors unique to animals
D. Shining colors as a sexual strategy
【答案】（1）D
（2）C
（3）C

【解析】【分析】本文是一篇说明文，介绍了彩虹色有助于生物隐藏。

（1）考查细节理解。

根据第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被动物用来通过逃离捕食者而活得更久，排除A；根据第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在这里我想指出的是，在某些物种中，尤其是那些表现出强烈两性差异的物种，比如天堂鸟、孔雀，甚至在某些蝴蝶或鱼类中，彩虹色的出现很可能是由性别选择所驱动的。

可知动物用彩虹色引起同伴的注意，排除B；根据倒数第二段中的“The idea that eye­catching colors could be used as a cover­up isn't a new one.”引人注目的颜色可以用来伪装，这种想法并不新鲜，排除C，故选D。

（2）考查细节理解。

根据最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我们的目标上惊人的彩虹表面在视觉上打破了原本可以辨认的目标形状，这使得它们很难区分。

故选C。

（3）考查推理判断。

根据最后一段说研究人员目前正在对鸟类进行实验，这些鸟类的饮食中经常含有彩虹色的昆虫。

实验目的是看看鸟类的视角是否能提供帮助。

由此推断接下来一段会谈论为什么鸟类不受彩虹色昆虫的影响，故选C。

（4）考查主旨大意。

第一段中的“Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”有时，最好的伪装其实是最耀眼的伪装，因为研究表明，闪光的金属彩虹色能在视觉上迷惑捕食者，这让五颜六色的猎物能够再存活一天，是全文的主题句，结合全文内容，可知这篇文章主要讲了彩虹色有助于生物隐藏，故选B。

【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。

4．犇犇阅读理解
Three-quarters of the world's coffee farms destroy forest habitat to grow coffee in the sun and typically use harmful pesticides (杀虫剂) and chemicals that poison the environment. When forests disappear, migratory (迁徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification.
Bird Friendly coffees are shade-grown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shade-grown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more complex flavor. Bird Friendly certified coffees grow under bio-diverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet.
Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional income. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat.
Buying Bird Friendly supports the Smithsonian Migratory Bird Center's conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped to your door when you order online.
（1）What is the present situation of coffee farms?
A. One fourth of them have destroyed forest habitat for birds.
B. Pesticides and chemicals used on them poisoned many birds.
C. Farmers have been aware of environment protection.
D. Scientists pay attention to them and have come up with an idea.
（2）What's a characteristic of Bird Friendly coffees?
A. They may have a better taste.
B. They have a strange flavor.
C. They take less time to ripen.
D. They are grown on unpolluted land.
（3）How can Bird Friendly farmers earn more money?
A. By charging consumers more money.
B. By selling fruits and wood from trees.
C. By cutting down trees and selling wood.
D. By serving as stewards of coffee consumers.（4）What does the text suggest coffee consumers do?
A. Consume less coffee.

A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.
The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.
"RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected," said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer
Science.
Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.
RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.
"While we are still in an early stage of development, our initial results with RAS have been promising," Minor said. "The next step in the research will be to test RAS' performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot."
（1）How does RAS serve elderly people?
A. Through sensors.
B. Through objects.
C. Through a mobile robot.
D. Through their daily activities.
（2）What can we know about RAS?
A. It is the first robot used in daily life.
B. Its function remains to be tested.
C. It can locate people and do any task.
D. It can cook for owners on its own.
（3）What's Minor's attitude toward the future of RAS?
A. Doubtful.
B. Negative.
C. Optimistic.
D. Uncertain.
（4）What can be a suitable title for the text?
A. Elderly people leave the nursing home.
B. Smart Home Tests first elder-Care robot.
C. RAS, the first robot to make home smart.
D. Older adults have benefited from RAS.
【答案】（1）A

6．阅读理解
An experimental cleanup device called RemoveDEBRIS has successfully cast a net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage. The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space.
Millions of pieces of junk are turning around in orbit the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical damage.
Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.
The RemoveDEBRIS experiment is run by a company and researchers led by the U. K.'s Surrey Space Center and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France's ArianeGroup.
Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.
The RemoveDEBRIS satellite will conduct a few more experiments in the coming months, including testing navigation features that could help guide the satellite to a specific piece of debris.
Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the success of this week's experiment was exciting, but he cautioned against "over- publicizing" it. There are still enormous barriers to clear before operational cleanup tasks are underway, he said, and the most discouraging is figuring out how to fund such projects.
Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said "The challenge will lie in persuading the relevant authorities to sponsor these tasks." Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.
（1）What is the use of the RemoveDEBRIS satellite?
A. Demonstrating space technology.
B. Imitating a developing technique.
C. Collecting wastes existing in space.
D. Symbolizing great progress in space.
（2）How does the RemoveDEBRlS satellite work?
A. By throwing a net to take the junk from orbit.
B. By fastening it to the main satellite tightly.
C. By dragging satellites up to 10 meters long.
D. By targeting large pieces of junk carefully.
（3）What does the underlined word "sponsor" in the last paragraph probably mean? A. Accomplish. B. Support. C. Oppose. D. Provide.
（4）What's the best title for the text?
A. The RemoveDEBRIS Project Is Perfect
B. How RemoveDEBRIS Is Invented in the Lab
C. Why the RemoveDEBRIS Satellite Is Invented
D. Satellite Collects Space Junk for the First Time

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.
