备战高考英语培优 易错 难题(含解析)之阅读理解及答案解析

一、高中英语阅读理解

1．阅读理解

Have you ever imagined what it would be like to see the world through an animal's eyes? For example, what a chimpanzee sees as it sits at the top of a tree, or a penguin's view as it dives into the sea to catch its dinner?

These questions are answered in the nature documentary Animals with Cameras, produced by the BBC. The three-part series was first aired in the UK last month. To explore animal stories "told" by the animals themselves, the documentary's filmmakers worked with scientists to develop cameras that wild animals could wear.

"Never before have we seen such high-quality footage (连续镜头)directly from the animal's point of view, " BBC Nature executive producer Fred Kaufman told PBS." This miniseries greatly expands our comprehension of animal behavior and this camera technology opens up new possibilities for discovering so much more."

Indeed, the groundbreaking technology provides a new viewpoint of the animal kingdom. New cameras with enough battery life to shoot for hours at a time were designed to be comfortable enough for animals to wear, according to the documentary's camera designer Chris Watts.

The technical challenges didn't stop there. Some animals were very curious about the equipment, with some even fighting each other for the chance to wear a camera. In the case of chimpanzees, "we had to create dummy (仿造的)cameras, so that every chimpanzee could get one", the miniseries' wildlife cameraman Gordon Buchanan told Live Science.

For animals that were comfortable enough to be with human beings, the cameras could be fitted and removed by hand. But for others, the cameras came off automatically using a timed release and were collected afterward. This meant that the cameras needed to be as tough as possible.

To avoid disturbing the animals, scientists who were good at dealing with wildlife came to help by putting the cameras on the animals." The last thing we want to do is cause them distress." the documentary's producer Dan Rees told the BBC. "To follow an animal in the first place, there had to be a clear benefit in terms of knowledge about it that might be useful to protecting a species in the future.

Their efforts certainly paid off. " Footage that captures (捕捉)these rare and exciting glimpses of animals bidden habits is important to scientists, but documentaries like Animals with Cameras also resonate with (引起共鸣)audiences, connecting them with the beauty - and danger - of wildlife in their natural environments," Live Science noted.

2．阅读理解

You're probably used to the regular upgrades in our cell-phone networks. There was 2G, which came along in 199l, replaced with 3G in 2001, followed by 4G in 2009. Now we're hearing about the coming of 5G.

But 5G is a much bigger leap than before. 5G, of course, is much faster than 4G in the real world and a 5G phone in a 5G city will enjoy Internet speeds between 9 and 20 times as fast. The arrival of 5G also means enormous leaps forward in capacity－so much that every cell-phone plan will offer cheap, truly unlimited Internet access. "The consequences of that are huge," says Sherif Hanna, Qualcomm's director of 5G marketing. For example, apps will no longer degrade (降低) your video quality or postpone downloading when you're out of Wi-Fi range. In fact, you'll probably prefer to do your downloads when you're on cellular (使用流量) because 5G will be much faster than whatever service you've got at home or work.

"However, not everyone is excited by the 5G development. The new standard gets its speed partly by using existing transmission(传输) frequencies more efficiently and partly by using the millimeter wave range. That's a big, juicy line of radio frequencies that are currently underused because millimeter wave is really hard to use," Hanna says.

These frequencies are much higher than anything we've used for the cellular, which means they can offer unbelievable speed－but at the cost of range. Millimeter wave cellular towers have to be about 500 feet apart. Cell carriers not only will have to upgrade all their cell transceivers (called small cells) but will install(安装) a lot more of them as well.

That's why the millimeter wave flavor of 5G, the superfast coverage, will be available only in densely populated cities such as New York and San Francisco. In suburban and rural areas, 5G will bring a speedup of "only" nine times faster.

（1）What advantages does 5G have over previous networks?

A. 5G is much faster and more convenient.

B. 5G allows users to download more videos.

C. 5G can provide better service and news at home.

D. 5G cell-phone plans are expensive but more accessible.

（2）Hanna's words in paragraph 3 reflect .

A. popularity of the coming of 5G

B. easy access to the 5G development

C. concern about the 5G development

D. excitement about the 5G development

（3）What can we learn about 5G according to the text?

A. It requires more cellular towers.

B. It won't be available in rural areas.

C. It won't show speed improvements in suburbs.

D. It makes some populated cities even more crowded.

（4）Where is the text most likely from?

A. A tour brochure.

B. A science newspaper.

C. A medical magazine.

D. An experimental textbook.

【答案】（1）A

（2）C

（3）A

（4）B

【解析】【分析】本文是一篇说明文，介绍了5G网络的一些基本情况。

（1）考查细节理解。根据第二段中的“But 5G is a much bigger leap than before. 5G, of course, is much faster than 4G in the real world and a 5G phone in a 5G city will enjoy Internet speeds between 9 and 20 times as fast.”但5G的发展比以前大得多。当然，在现实世界中，5G比4G快得多，5G城市中的5G手机将享受9到20倍的网速。可知，5G手机的网速将大幅度提高。由此可知，与以前的网络相比，5G更快、更方便。故选A。

（2）考查推理判断。根据第三段中的“‘However, not everyone is excited by the 5G development…That's a big, juicy line of radio frequencies that are currently underused because millimeter wave is really hard to use,’ Hanna says.”汉纳说:“然而，并不是每个人都对5G的发展感到兴奋……这是一个巨大的、有趣的无线电频率线，目前还没有得到充分利用，因为毫米波真的很难使用。”可知，汉纳认为并不是每个人都对5G的发展感到兴奋，这种无线电频率线，目前还没有得到充分利用。由此推知，汉纳在第3段中的话反映了对5G发展的担忧。故选C。

（3）考查细节理解。根据第四段中的“Cell carriers not only will have to upgrade all their cell transceivers (called small cells) but will install(安装) a lot more of the m as well.”手机运营商不仅要升级他们所有的手机收发器(称为小型小区，还要安装更多的收发器）可知，5G不仅需要手机运营商升级他们所有的手机收发器，还要安装更多的收发器。可推知，5G需要更多的手机基站。故选A。

（4）考查推理判断。根据第一段中的“There was 2G, which came along in 199l, replaced with 3G in 2001, followed by 4G in 2009. Now we're hearing about the coming of 5G.”1991年出现的2G, 2001年被3G取代，2009年又出现了4G。现在我们听到了5G的到来。可知，本文主要介绍了5G网络的一些基本情况。5G网络的发展属于科技进步，结合选项可知，本文应该来自科学报纸。故选B。

3．阅读理解

I became a magician by accident. When I was nine years old, I learned how to make a coin disappear. I'd read The Lord of the Rings and risked coming into the adult section of the library to search for a book of spells (魔法) — nine being that curious age at which you're old enough to work through more than 1, 200 pages of mysterious fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found instead taught basic sleight-of-hand (戏法) technique, and I devoted the next months to practice. Initially, the magic wasn't any good. At first it wasn't even magic; it was just a trick — a bad trick. I spent hours each day in the bathroom running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks of this my mom got a carpet sample from the store and placed it under the mirror to eradicate the sound of the coin falling again and again.

I had heard my dad work through passages of new music on the piano, so I knew how to practice — slowly, deliberately, going for precision rather than speed. And then I tried the illusion (错觉) in the mirror and an unbelievable scene took place. It did not look like a magic trick. It looked like a miracle. I knew that I had got what I wanted.

One day I made the performance on the playground. We had been playing football and were standing by the backstop in the field behind the school. A dozen people were watching. I showed the coin to everyone. Then it disappeared. The kids screamed. They yelled, laughed, scrambled away. Everyone went crazy. This was brilliant.

（1）What did the author enter the adult section of the library to do?

A. To kill his time.

B. To find a book of magic. C To read The Lord of the Rings. D. To learn knowledge of literature.（2）What does the underlined word "eradicate" in Paragraph 2 mean?

A. Get rid of.

B. Give out.

C. Imitate.

D. Distinguish.

（3）What contributed to the author's success?

A. His mother's help.

B. The secret of quick moves.

C. The inspiration from his father.

D. His repeated hard practice.

（4）How would the author feel about the result of his performance on the playground?

A. It's fantastic.

B. It's funny.

C. It's awkward.

D. It's disappointing.

【答案】（1）B

（2）A

（3）C

（4）A

【解析】【分析】本文是一篇记叙文，作者变成魔术师是偶然的，并且具体讲述了自己九岁时学习如何让硬币消失的经历。

（1）考查细节理解。根据第一段中的“I'd read The Lord of the Rings and risked coming into the adult section of the library to search for a book of spells ”我读过《魔戒》，并且冒险进入图书馆的成人区寻找魔法书，可知，作者进入图书馆的成人区是为了寻找魔法书。原文中使用了不定式表达目的。故选B。

（2）考查词义猜测。根据第二段讲述作者一开始练习让硬币消失时的练习经历，他每天要在镜子前练1000遍左右，那么硬币也就会掉在地上1000次左右。所以划线单词所在句子句意应为：两周后，妈妈从店里买了一块地毯，把它放在镜子下面，以掩盖硬币一次又一次落下的声音。故选A。

（3）考查推理判断。根据第三段中的“I had heard my dad work through passages of new music on the piano, so I knew how to practice — slowly, deliberately, going for precision rather than speed. And then I tried the illusion (错觉) in the mirror and an unbelievable scene took place. It did not look like a magic trick. It looked like a miracle.”可知，作者是在父亲练习钢琴的经历的启发下，领悟到了练习的真谛，最终取得了成功。故选C。

（4）考查推理判断。根据最后一段中的“They yelled, laughed, scrambled away. Everyone went crazy. This was brilliant.”，可知作者在操场上表演完硬币消失之后，其他同学欢呼、大小并且都不知道是如何做到的，每个人都很疯狂。作者认为这个经历是非常棒的。故选

A。

4．阅读理解

Imagine a school where self-awareness is celebrated, students are encouraged to solve maths problems by writing on the walls and applying learned lessons to real life is more important than homework. These are a few of the concepts that makes Space of Mind School unique.

Located in a home built in 1896 in Florida, US, the program serves students in grades 2 through 12 and will accept kindergarten students next year. It also offers an after-school program for students who attend traditional schools, as well as evening programs for adults and educators and weekend events for families.

There is a different atmosphere from that of a traditional school building. Tables and brightly colored walls are white boards. In the science room, students are studying climate changes at a weather station, while in the music room, a student is solving an equation (等式) with his academic coach while he connects music theory and maths.

The daily schedule at the school also stands out. "We don't assign boring or exhausting homework." said Space of Mind founder and CEO Ali Kaufman. "Instead of homework, we ask that they go home and take a video of themselves applying a lesson they learned or cooking a meal for their family that they learned how to make at school."

For lunch, instead of traditional cafeteria dishes such as pizza, the school offers organic meals made out of products from local gardens and farms. "Our students also run a business at the Delray Beach Green Market on Saturdays so they can understand sustainable living practices and how to run a business," Kafman said.

" We are also the first school program in Florida to start and end each day with 15 minutes of meditation (冥想)," Kaufman said. "The positive results we have been seeing in the students from meditation are amazing. We are really about infusing social, emotional and creative skills with academic and life skills."

（1）Space of Mind School_________.

A. assigns no homework.

B. urges students to use what they learn.

A. Yoga enjoys great popularity in US.

B. The practice of meditation is amazing.

C. The meditation session lasts 15 minutes daily.

D. The students benefit from meditation.（3）The underlined word "infusing" in the last paragraph probably means______.

A. emphasizing

B. checking

C. developing

D. helping

（4）What is the text mainly about?

A. What makes Space of Mind School outstanding.

B. Why Space of Mind School is popular in US.

C. How the after-class programs of space of Mind School are organized.

5．阅读理解

The age of adulthood is by definition arbitrary. If everyone matured at the same, fixed rate, it wouldn't be a human process. Indeed, maturation happens at varying speeds across different categories within the same individual, so I'd say I was easily old enough to vote at 16, but nobody should have given me a credit card until I was 32, and I've got the county court judgment to prove it.

However, we broadly agree that there's a difference between a child and an adult, even if we might argue about the transition point. So the political theorist David Runciman's view that six-year-olds should be allowed to vote goes against any standard argument about the age of civic responsibility. Nobody would say that a six-year-old could be held criminally responsible, could be sent to war, could be capable of consent, could be given responsibility for anything. So allowing them the vote—along with, unavoidably, seven-year-olds who are even sillier, if anything—is

quite an amusing proposal.

Runciman's argument is that this is the only way to rebalance political life, which is currently twisted in favor of the old, who don't (he added) ever need to demonstrate mental capacity, even long after they've lost it.

The first part of his case is self-evident: pensions are protected while children's centers are closed, concepts such as sovereignty (最高权威) are prioritized over the far more urgent business of the future: climate change. Nostalgia (怀念) for a past the young wouldn't even recognize plays a central role, which is completely unfair.

Most of the arguments against giving six-year-olds a vote are that children would end up voting for something damaging and chaotic, if someone made unrealistic promises to them, which could never be realized. Well, it's not children's fault.

Having said that, children do tend towards the progressive, having a natural sense of justice (which kicks in at the age of six months, psychologists have shown, by creating scenes of great unfairness to babies, and making them cry) and an underdeveloped sense of self-interest. My kid, when he was six, made quite a forceful case against private property, on the basis that, since everybody needed a house, they shouldn't cost money, because nobody would want anyone else not to have one. Also, food should be free. It was a kind of pre-Marx communism, where you limit the coverage of the market to only those things that you wouldn't mind someone else not having.

On that particular day, when we were registered as voters, my kid was quite far to the left of me, but in the normal run of things, we're united, which brings us to the point of the problem: children obey you on almost nothing, but they do seem to believe in your politics until they're adolescent. So giving kids the vote is really just a way of giving parents extra votes. And what can stop us having even more children, once there's so much enfranchisement (选举权) in it for us? Now, if parents could be trusted to use their influence wisely, and hammer into children the politics it will take to assure a better future, then I wouldn't necessarily have a problem with that, apart from, obviously, that culture is already wildly twisted towards parents, and I can imagine a few non-parents boiling with fierce anger. But that's not worth talking about anyway, because parents can't be trusted, otherwise we'd all already vote Green(绿党).

In short: no, six-year-olds should not get the vote; but while we're here, if any votes come up in the near future, which will have an impact on the next five decades of British political life, alongside EU migrants, 16-year-olds certainly should be enfranchised.

（1）The author refers to his age of adulthood to prove that ________.

A. certain rights are granted at different stages of life

B. there's a common standard for the age of adulthood

C. people mature at different rates in various aspects

D. a credit card is more difficult to get than the vote

（2）People reject David Runciman's proposal because ________.

A. they believe children are far from mature in many ways

B. they are uncertain whether children can assume responsibility

C. they know the age to get the vote is not to be questioned

D. they don't think a child can grow into adulthood earlier

（3）What is the base for David Runciman's argument?

A. Public ignorance of children's abilities.

B. Inequalities of opportunity.

C. A cultural preference for the old.

D. The imbalance in political life.

（4）The author talks about his kid to indicate that ________.

A. children are in favor of a just society and tend to be idealistic

B. children are innocent and don't want to be involved in politics

C. children are simple-minded and can fall for an adult's trick

D. children are good-natured and like to help people in need

（5）The author thinks allowing children the vote may lead to ________.

A. twisted culture

B. parents' objections

C. misuse of rights

D. unusual maturation （6）What is the main point of the passage?

A. There is a difference between adults and children.

B. Allowing children the vote is not altogether absurd.

【解析】【分析】本文是一篇议论文，讲述了儿童成熟的速度是不同，所以作者认为允许儿童投票的提议并不完全是荒谬的，如果将对未来50年的英国政治生活产生影响，16岁的孩子应该被授予选举权。

（1）考查细节理解。根据第一段中的“Indeed, maturation happens at varying speeds across different categories within the same individual, so I'd say I was easily old enough to vote at 16, but nobody should have given me a credit card until I was 32, and I've got the county court judgment to prove it.”可知，作者以他的成熟年龄来证明人们在各个方面的成熟速度是不一样的。故选C。

（2）考查推理判断。根据第二段中的“Nobody would say that a six-year-old could be held criminally responsible, could be sent to war, could be capable of consent, could be given responsibilit y for anything.”没人说6岁的孩子会被追究刑事责任，会被送上战场，会有同意的能力，会被赋予任何责任。由此推断，人们拒绝David Runciman的提议是因为他们认为孩子在很多方面还不够成熟，不能被赋予相应的责任。故选A。

（3）考查细节理解。根据第三段中的“Runciman's argument is that this is the only way to rebalance political life”可知，Runciman论点的基础是，这是重新平衡政治生活的唯一途径，即政治生活的不平衡导致他提出这个提议。故选D。

（4）考查推理判断。根据倒数第四段中的“My kid, when he was six, made quite a forceful case against private property, on the basis that, since everybody needed a house, they shouldn't

cost money, because nobody would want anyone else not to have one. Also, food should be free. It was a kind of pre-Marx communism, where you limit the coverage of the market to only those things that you wouldn't mind someone else not having.”可知，孩子反对私有财产，因为他们觉得每个人需要房子，他们不应该花钱买房，此外食物也应该是免费的，这是一种前马克思共产主义的想法，由此可推测孩子更加公平，更期待理想社会。故选A。

（5）考查推理判断。根据倒数第三段中的“So giving kids the vote is really just a way of giving parents extra votes.”可知，给孩子投票权其实只是给父母额外投票权的一种方式，由此推断作者认为给孩子投票权可能会导致投票权的滥用。故选C。

（6）考查主旨大意。根据最后一段“In short: no, six-year-olds should not get the vote; but while we're here, if any votes come up in the near future, which will have an impact on the next five decades of British political life, alongside EU migrants, 16-year-olds certainly should be enfranchised.”可知，作者认为6岁的孩子不应该获得选举权，但是如果将来有任何会影响英国以及欧盟移民未来50年政治生活的投票出现话，16岁的孩子应该被赋予选举权，由此可知作者认为儿童被赋予选举权并不完全是荒谬的。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，是一篇社会类阅读，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。

6．阅读理解

Microsoft announced this week that its facial-recognition system is now more accurate in identifying people of color, touting (吹嘘)its progress at tackling one of the technology's biggest biases (偏见).

But critics, citing Microsoft's work with Immigration and Customs Enforcement, quickly seized on how that improved technology might be used. The agency contracts with Microsoft for cloud-computing tools that the tech giant says is largely limited to office work but can also include face recognition.

Columbia University professor Alondra Nelson tweeted, "We must stop confusing 'inclusion' in more 'diverse' surveillance (监管)systems with justice and equality."

Facial-recognition systems more often misidentify people of color because of a long-running data problem: The massive sets of facial images they train on skew heavily toward white men. A Massachusetts Institute of Technology study this year of the face-recognition systems designed by Microsoft, IBM and the China-based Face++ found that facial-recognition systems consistently giving the wrong gender for famous women of color including Oprah Winfrey, Serena Williams, Michelle Obama and Shirley Chisholm, the first black female member of Congress.

The companies have responded in recent months by pouring many more photos into the mix, hoping to train the systems to better tell the differences among more than just white faces. IBM said Wednesday it used 1 million facial images, taken from the photo-sharing site Flickr, to build the "world's largest facial data-set" which it will release publicly for other companies to use.

IBM and Microsoft say that allowed its systems to recognize gender and skin tone with much more precision. Microsoft said its improved system reduced the error rates for darker-skinned

men and women by "up to 20 times," and reduced error rates for all women by nine times.

Those improvements were heralded(宣布)by some for taking aim at the prejudices in a rapidly spreading technology, including potentially reducing the kinds of false positives that could lead police officers misidentify a criminal suspect.

But others suggested that the technology's increasing accuracy could also make it more marketable. The system should be accurate, "but that's just the beginning, not the end, of their ethical obligation," said David Robinson, managing director of the think tank Upturn.

At the center of that debate is Microsoft, whose multimillion-dollar contracts with ICE came under fire amid the agency's separation of migrant parents and children at the Mexican border.

In an open letter to Microsoft chief executive Satya Nadella urging the company to cancel that contract, Microsoft workers pointed to a company blog post in January that said Azure Government would help ICE "accelerate recognition and identification." "We believe that Microsoft must take an ethical stand, and put children and families above profits," the letter said.

A Microsoft spokesman, pointing to a statement last week from Nadella, said the company's "current cloud engagement" with ICE supports relatively anodyne(温和的)office work such as "mail, calendar, massaging and document management workloads." The company said in a statement that its facial-recognition improvements are "part of our going work to address the industry-wide and societal issues on bias."

Criticism of face recognition will probably expand as the technology finds its way into more arenas, including airports, stores and schools. The Orlando police department said this week that it would not renew its use of Amazon. com's Rekognition system.

Companies "have to acknowledge their moral involvement in the downstream use of their technology,"

Robinson said. "The impulse is that they're going to put a product out there and wash their hands of the consequences. That's unacceptable."

（1）What is "one of the technology's biggest biases" in Paragraph 1?

A. Class bias.

B. Regional difference.

C. Professional prejudice.

D. Racial discrimination.

（2）What can we know about the improvement of facial-recognition technology?

A. Justice and equality have been truly achieved.

B. It is due to the expansion of the photo database.

C. It has already solved all the social issues on biases.

D. The separation of immigrant parents from their children can be avoided.

（3）What is the focus of the face-recognition debate?

A. Data problems.

B. The market value.

C. The application field.

D. A moral issue.（4）What is David Robinson's attitude towards facial-recognition technology?

A. Skeptical.

B. Approval.

C. Optimistic.

D. Neutral.

（5）We can infer from the last paragraph that Robinson thinks _____.

A. companies had better hide from responsibilities

B. companies deny problems with its technical process

C. companies should not launch new products on impulse

D. companies should be responsible for the new product and the consequences

（6）Which can be the suitable title for the passage?

A. The wide use of Microsoft system

B. Fears of facial-recognition technology

C. The improvement of Microsoft system

D. Failure of recognizing black women

（1）考查推理判断。根据第一段”Microsoft announced this week that its facial-recognition system is now more accurate in identifying people of color, touting (吹嘘）its progress at tackling one of the technology's biggest biases (偏见).“可知微软面部识别技术改进了肤色识别，吹嘘它可以解决该技术最大的偏见，由此可以推断该项技术在人种肤色上有偏见，也就是种族歧视。故选D。

（2）考查细节理解。根据第五段中的”The companies have responded in recent months by pouring many more photos into the mix, hoping to train the systems to better tell the differences among more than just white faces.“可知那些公司通过在原有照片中加入更多的照片，通过训练系统，从而提升系统的识别能力，即通过扩充照片数据库来提升系统的识别能力。故选B。

（3）考查推理判断。根据第九段中的”At the center of that debate is Microsoft, whose multimillion-dollar contracts with ICE came under fire amid the agency's separation of migrant parents and children at the Mexican border.“；和第十段中的”We believe that Microsoft must take an ethical stand, and put children and families above profits“可知对微软人脸识别技术的争论中心是，它会把墨西哥边缘的移民父母和孩子分开，且人们认为微软必须坚守道德底线，将儿童和家庭置于其利润之上，故推断目前对于脸部识别技术争论的焦点是道德问题。故选D。

（4）考查推理判断。根据最后一段中的 "The impulse is that they're going to put a product out there and wash their hands of the consequences. That's unacceptable."可知Robinson认为他们推出了一种产品然后对其后果撒手不管，这是让人难以接受的。故推断Robinson对人脸识别技术是不支持的。故选A。

（5）考查推理判断。根据最后一段中的 "The impulse is that they're going to put a product out there and wash their hands of the consequences. That's unacceptable."可知Robinson认为他们推出了一种产品然后对其后果撒手不管，这是让人难以接受的。故推断Robinson认为公司应该对自己的产品和产品带来的后果负责到底。故选D。

（6）考查主旨大意。纵观全文可知，本文讲述了人们怀疑改进之后的人脸识别技术会带

来更多的问题，比如种族歧视和置墨西哥孩子的利益于不顾。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，是一篇科技类阅读，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。

Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.

For species(物种)like chimpanzees which have complex social lives and live for many years, getting photos of their behavior taken from short-term field research can only tell us so much," says Dan Schofield, researcher and DPhil student at Oxford University's Private Models Lab, School of Anthropology. "By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term."

The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality. "Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible," says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science, University of Oxford." Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预), saving hours of time."

The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other

species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.

Cassandra Feeley finds it hard to manage on her husband's income. So this year she did something more than a hobby. She planted vegetables in her yard. For her first garden, Ms. Feeley has put in 15 tomato plants, and five rows of a variety of vegetables. The family's old farm house has become a chicken house, its residents arriving next month. Last year, Ms. Rita Gartin kept a small garden. This year she has made it much larger because, she said, "The cost of everything is going up and I was looking to lose a few pounds too; so it's a win-win situation all around."

They are among the growing number of Americans who, driven by higher living costs and a falling economy, have taken up vegetable gardening for the first time. Others have increased the size of their existing gardens. Seed companies and garden shops say that not since the 1970s has there been such an increase in interest in growing food at home. Now many gardens across the country have been sold out for several months. In Austin, Tex, some of the gardens have a three-year waiting list.

George C Ball Jr. owner of a company, said sales of vegetable seeds and plants are up by 40%, over last year, double the average growth of last five years. Mr. Ball argues that some of the reasons have been building for the last few years. The big one is striking rise in the cost on food like bread and milk, together with the increases in the price of fruit and vegetables. Food prices have increase of higher oil price. People are driving less, taking fewer vacations, so there is more time to garden.

Plastic sludge(污泥)and garbage is a disaster for the world's oceans. A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. “Half of the waste actually sinks to the bottom, and that remains on the surface act ually breaks down. ”

The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacifc Oceans, home of what some have plastic. What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant. ”

The pieces of the plastic garbage infect the food chain, sometimes visibly, and more so at the microscopic level, where the plastic particle s interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while it acts like magnets(磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances ente r the fatty tissues. ”To be consumed by other sea life and by people at last. China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters. The United States, although a leader in recycling, is one of the world's 20 since it produces and consumes so much plastic. There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon(黎巴嫩).

11．（2019?江苏）请认真阅读下列短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项。

In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before: he couldn't find the park's volcano. It had been known for a long time that Yellowstone was volcanic in nature—that's what accounted for all its hot springs and other steamy features. But Christiansen couldn't find the Yellowstone volcano anywhere.

Most of us, when we talk about volcanoes, think of the classic cone (圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma (岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second les known type of volcano that doesn't involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn't find the caldera anywhere.

Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera; almost the whole park-2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.

（1）What puzzled Christiansen when he was studying Yellowstone?

A. Its complicated geographical features.

B. Its ever-lasting influence on tourism.

C. The mysterious history of the park.

D. The exact location of the volcano.

（2）What does the second-paragraph mainly talk about?

A. The shapes of volcanoes.

B. The impacts of volcanoes.

C. The activities of volcanoes.

D. The heights of volcanoes.

（3）What does the underlined word "blow-up" in the last paragraph most probably mean?

A. Hot-air balloon.

B. Digital camera.

C. Big photograph.

D. Bird's view.

【答案】（1）D

（2）A

（3）C

【解析】【分析】本文是一篇记叙文，二十世纪六十年代Bob Christiansen在研究黄石公园的火山历史时，奇怪地发现到处看不到火山的影子，原来，这儿的火山并不是像我们大部分人想象的那种圆锥体形状的高耸的样子，而是一个巨大的洞，这个洞太大了以至于从地面上的任何地方都看不见。

（1）细节理解题。根据第一段中的“But Christiansen couldn't find the Yellowstone volcano anywhere.”可知，他困惑的是到处看不到火山。故选D。

（2）段落大意题。本段讲述了两种形状的火山，一种是通常人们所理解的由火山岩浆堆积形成的圆锥体，还有一种极具爆发力的火山，它们会在一个大裂缝中爆裂，留下一个巨大的洞，故选A。

（3）词义猜测题。根据第三段中的“Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers.”可知，美国国家航空和宇宙航行局为测试一些新的高海拔照相机而拍摄了黄石公园的照片。一位深思熟虑的官员把其中的一些照片副本转交给了公园管理部门，认为他们可能会将其放大以供一个游客中心展示。故可知，此处意为将照片放大。故选C。

12．阅读理解

Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.

（1）What is the purpose of mentioning the question in Paragraph 1?

A. To introduce the new giant telescope.

B. To explain why there is life in universe.

C. To remind readers to think about the life in space.
