一、高中英语阅读理解

1．阅读理解

Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available soon.

The British company Malloy Aeronautics has developed a prototype (原型) of its flying bicycle. Grant Stapleton, marketing sales director of Malloy Aeronautics, says the Hoverbike is able to get in and out of small spaces very quickly. It can be moved across continents very quickly because it can be folded and packed, he adds.

Mr. Stapleton says safety was the company's main concern. He says the designers solved the safety issue by using overlapping rotors ( 交叠式旋翼 )to power the vehicle.

The company is testing a full-size prototype of the Hoverbike, which will most likely be used first by the police and emergency rescue teams.

In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying device, called the Jetpack. It can fly for more than 30 minutes, up to 1,000 meters high and reach a speed of 74 kilometers per hour.

Peter Coker is the CEO of Martin Aircraft Company. He said the Jetpack “is built around safety from the start. In his words, reliability is the most important element of it. We have safety built into the actual structure itself, very similar to a Formula O ne racing car.”

The Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞) that can be used should there be an emergency. “It starts to work at very low altitude and actually saves bo th the aircraft and the pilot,” he adds. Mr. Coker says the Jetpack will be ready for sale soon.

（1）We can learn from the passage that the Hoverbike .

A. can hardly get in and out of small spaces quickly

B. can fly for over 30 minutes, up to 1,000 meters high

C. has been used by the police and emergency rescue teams

D. can be transported quickly after being folded and packed

（2）The writer uses the example of For One racing car to show that .

A. the Jetpack is very safe and reliable

B. the engine of the Jetpack is powerful

C. the actual structure of the Jetpack is unique

D. the Jetpack can reach a great speed and height

（3）The underlined word “it” in the last paragraph refers to.

A. the jet stream

B. the engine

C. the Jetpack

D. the parachute （4）What is the authors main purpose of writing the passage?

A. To describe the problems of inventing flying vehicles.

B. To introduce the latest development of flying vehicles.

C. To show the differences between two flying vehicles.

D. To advertise the two personal

flying vehicles.

【答案】（1）D

（2）A

（3）D

（4）A

【解析】【分析】本文为说明文，主要讲述一种个人飞行工具很快就会应用于现实。然而安全性和强度一直是个大问题。文中介绍了两家飞器公司都关注安全性问题。

（1）细节理解题。第五段最后一句可知，the Jetpack.可飞行30分钟，高达1000米，而不是Hoverbike，故B错误，根据第四段可知C项说有将可能首先应用于由警察和应急救援队，而不是已用于，故C错误。根据第二段最后the Hoverbike is able to get in and out of small spaces very quickly. It can be moved across continents very quickly because it can be folded and packed, 可知，Hoverbike能够很快地进出小空间。它可快速地在大陆上移动，因为它可以折叠和包装。分析选项可知，A说不能快速进入小空间，故错误。D项说在折叠和包装后可以快速运输。即D正确。故选D。

（2）推理判断题。第六段Peter Coker说Jetpack从一开始就围绕安全进行的。安全可靠性是最重要的因素。我们在车的现行结构中植入了了安全性，非常类似于Formula One赛车。分析选可知A项（Jetpack安全可靠）符合题意，故答案选A。

（3）猜测词义题。根据最后一段Mr. Coker says it also has a parachute (降落伞) that can be used should there be an emergency. “It starts to work at very low altitude …., Coker先生说Jetpack上也有降落伞，可以在紧急情况下使用。“在海拔非常低的情况下开始用它…”。由此可知，Jetpack上的降落伞（它）是在海拔低时才用。由此可知it指的是parachute (降落伞) 故答案选D。

（4）主旨大意题。根据第一段可知，许多人一直梦想能像骑自行车一样飞来飞去，科技的发展让这个梦想很快实现。然而飞行自行车的安全性和强度一直是个大问题。接着下面叙述了这种飞行器的问题最重要的是安全问题。分析选项，可知A项描述发明飞行器的问题，符合题意，故答案选A。

3．阅读理解

Bamboo is one of the world's most useful plants. For thousands of years, bamboo has been used in many different ways-from food to medicine to clothing and, in small ways, as a building material.

However, bamboo is not often used as a building material in the developed world. A professor at the University of Pittsburgh in Pennsylvania is trying to change that. The professor and his students are testing the strength of bamboo.They are testing how much pressure or weight it can take before breaking.

Kent Harries is a professor at the University of Pittsburgh. Harries says that testing methods for bamboo need to be the same for all. They need to be standardized. Standardizing test methods for bamboo will help to bring the plant into common use. It will also give engineers and builders around the world a dependable standard.

Harries says that bamboo is strong in nature. The strength of at least three species of bamboo is similar to steel.Besides its strength, bamboo has other features that make it very useful in building. He says it is resilient(有弹力的), meaning it keeps its shape and strength even under pressure.

Bamboo also grows quickly. Bamboo that is suitable for construction needs much less resources than wood. The harvest cycle of bamboo is about 3 years. Softwoods such as cedar, pine and spruce have a harvest cycle of about 10 years. And hardwoods that come from flowering plants such as oak and walnut need more than 30 years.

Bamboo is widely used as food for panda bears. It is also used for flooring and window covers. However, for building, bamboo is not used much outside its native growing area. This is mostly because of its round shape. But there are other reasons too. People think -- or have the mentality--that bamboo is a low quality building material.

（1）What is the author mainly talking about in the passage?

A. Make bamboo a common building material.

B. Take advantage of bamboo in our everyday.

C. Consider bamboo to be a common plant.

D. Use bamboo to replace building materials.（2）What is the purpose of what Kent Harries and his students did?

A. To prove what is the most useful plant.

B. To introduce bamboo to the developed world.

C. To give engineers and builders some advice.

D. To make sure of the strength of bamboo.（3）What does Harries think of bamboo in the passage?

A. Harries sees bamboo as a great building material.

B. Harries thinks bamboo is as strong as steel.

C. Harries sees bamboo as the most ideal Plant.

D. Harries thinks bamboo has the reliable shape.

（4）What can be inferred from the passage?

A. Bamboo is an environmentally friendly building material.

B. Bamboo material will go to the market in the soon future.

C. Hardwoods are much more popular than softwoods.

D. Bamboo grows not only faster but takes up less space.

【答案】（1）A

4．阅读理解

A bite from a tsetse fly (采采蝇) is an extremely unpleasant experience. It is not like a mosquito, which can put its thin mouthpart directly into your blood, often without you noticing. In contrast, the tsetse fly's mouth has tiny saws on it that saw into your skin on its way to suck out your blood.

To make matters worse, several species of tsetse fly can transmit diseases. One of the most dangerous is a parasite that causes ＂sleeping sickness＂, or ＂human African trypanosomiasis＂to give it its official name. Without treatment, an infection is usually fatal.

Like so many tropical diseases, sleeping sickness has often been neglected by medical researchers. However, researchers have long endeavored to understand how it avoids our bodies' defence mechanisms. Some of their insights could now help us eliminate sleeping sickness altogether.

There are two closely-related single-celled parasites that cause this deathly sleep: Trypanosoma brucei rhodesiense and T. b. gambiense. The latter is far more common: it is responsible for up to 95% of cases, mostly in western Africa. It takes several years to kill a person, while T. brucei rhodesiense can cause death within months. There are still other forms that infect livestock.

After the initial bite, sleeping sickness symptoms often start with a fever, headaches and aching muscles. As the illness goes on, those infected become increasingly tired, which is where it gets its name. Personality changes, severe confusion and poor coordination can also happen.

While medication does help, some treatments are toxic and can themselves be deadly, especially if they are given after the disease has reached the brain.

It is worth noting that sleeping sickness is no longer as deadly as it once was. In the early 20th Century several hundred thousand people were infected each year. By the 1960s the disease was considered ＂under control＂and had reached very low numbers, making its spread more difficult. But in the 1970s there was another major epidemic, which took 20 years to control.

Since then, better screening programmes and earlier interventions have reduced the number of cases dramatically. In 2009 there were fewer than 10,000 cases for the first time since records began, and in 2015 this figure dropped to fewer than 3,000, according to the latest figures from the World Health Organisation. The WHO hopes the disease will be completely eliminated by 2020.

While this decline looks positive, there may be many more cases that go unreported in rural Africa. To eliminate the disease completely, infections have to be closely monitored.

More problematically, a series of new studies have shown that the parasite is more complicated than previously believed.

Sleeping sickness has always been considered ——and diagnosed ——as a blood disease, because T. brucei parasites can readily be detected in the blood of its victims.

（1）A tsetse fly is different from a mosquito in that________.

A. it can put its thin mouthpart directly into your blood

B. all species of tsetse fly can transmit diseases

C. it can spread a parasite that causes ＂sleeping sickness＂

D. its mouth has larger saws than those on a mosquito

（2）What can be learned about ＂sleeping sickness＂ according to the text ?

A. It is formally called＂human American trypanosomiasis＂.

B. If left untreated, it can possibly be deadly.

C. It remains as deadly as it used to be.

D. It usually draws attention from medical researchers.

（3）What is implied in the last three paragraphs ?

A. ＂Sleeping sickness＂ will be completely eliminated by 2020.

B. The parasite causing ＂sleeping sickness＂ is easy to detect now.

C. T. brucei parasites can only be detected in the blood of its victims.

D. Data about ＂sleeping sickness＂cases may not be so accurate.

（4）What would be the best title of this passage ?

A. A mosquito that can carry deadly diseases.

B. A bite from this fly puts you into a deadly sleep.

C. Symptoms that are characteristic of ＂sleeping sickness＂.

D. How to control deadly＂sleeping sickness＂ from a tsetse fly.

【答案】（1）C

A Song of Ice and Fire is a seven-part series of fantasy written for adults. George R. R. Martin writes each chapter from the perspective of a specific character, providing a limited point of view for each section. The reader is able to understand the inner workings of the individual, but the reader is barred from a whole understanding of the text. The world he has created has magic, but there is much more than that. While magic exists, it exists on the edge, and the inner unrest of the characters is much more important.

His work also has a level of realness that is astonishing in a work of fantasy. Characters are imperfect, and many make questionable moral choices. In the end, however, Martin shows that

both good and bad happen to both the people of high moral standard and the corrupt. He has made it clear that any character can die at any point, which has led to a lot of heartbreak from readers.

In 2011, A Song of Ice and Fire became a television series titled Game of Thrones. Martin has been closely involved with the production. It has currently run for seven seasons, and viewers anxiously await the eighth season to answer their questions from the season seven finale.

His fans are also waiting for The Winds of Winter and A Dream of Spring, the next books in the series, to answer the questions Martin and the television show have not yet addressed. Martin, however, has no plans to rush. He has made it clear that he will continue to write the books while working on the television show and writing other novels.

But how will the story continue? What is going to happen in Westeros, and more importantly: when are we going to find out? Martinis skill as a writer has kept readers and viewers spellbound. Many hope he will finish the next book before the next season of the show begins, but no one knows with Martin. He always keeps his readers guessing.

Apple announced its new iPhones last week, but competitors' mobile phones can do many of the same things for less money.

The new iPhone 8 and X have wireless charging, edge-to-edge glass screen and double cameras. But all of these features are already available in smart phones from China's Huawei and Oppo, and Korea's Samsung. While Apple asks buyers to pay $1,000 for its high-end model, some Asian phone makers can offer similar features for less.

At one time, Chinese manufacturers copied features and designs from others to produce low-cost phones. But they have now added high-end features to their phones and they control nearly half the global mobile phone market.

Media MarktSaturn is Europe's biggest electronics seller. A spokesperson for the store told Reuters that,“Huawei is seen as a relevant competitor to Apple and Samsung by covering all major price points and placing big investments in marketing and sales. '' She also said that the Chinese companies Huawei, ZTE, Lenovo and TCL were among the top-10 best-selling smart phones in its stores.

Chinese manufacturers' fast growth has been fueled by strong sales in China. But they now export 40 percent of their smart phones. That is almost double the number from just three years ago, according to the Hong Kong investment company CLSA.

Huawei is currently the world's third largest phone maker behind Samsung and Apple. According to research company Canalys, the Chinese company is getting closer to second-place Apple and might overtake it later this year.The Chinese company even made fun of Apple's new facial recognition feature with a Facebook video called "Real AI phone." Huawei plans to show its top-of-the-line Mate 10 phone on Oct. 16. The phone will have artificial intelligence features such as instant translation and image recognition and will cost less than $1,000. Other Chinese companies are looking to enter the high-end smart phone market.

We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide" said researchers from the National University of Singapore.

45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.

" We do not yet know the mechanisms(机制)involved, or why some organism are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify."

The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.

Warm-blooded animals aren't immune(免除)from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.

This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.

The speed of modem climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.（1）What does the text mainly talk about?

A. Why some species become smaller.

B. How climate changes in Earth's history?

C. Climate change has many negative effects.

D. Species are becoming smaller as climate gets warmer.

（2）The underlined word "trumped" m the first paragraph probably mean_________. A. strengthened B. gained C. beaten D. equaled （3）Researchers from the National University of Singapore believe that________.

A. they have found the exact causes for creatures getting smaller

B. all the animals on the earth have become smaller

C. climate change has more negative effects on warm-blooded animals

D. increase in energy use can lead to creatures getting smaller

（4）What does the author feel about the climate change?

A. Disappointed

B. Optimistic

C. Worried

D. Shameful 【答案】（1）D

（2）C

（3）D

（4）C

Nowadays, especially in China, everything seems to favor social intercourse(社交) , such as gatherings of friends, KTV, group travel, dining tighter, playing cards and Mahjong, plus the Chinese-style " street-crossing group." Back home, discussions can still be boisterously carried on within the "circle of friends" of WeChat.

However, these scenes cannot always ease a sense of loneliness. Zhu Ziqing, a well-known professor of Tsinghua University, signed with emotion: "My loneliness increases as scene becomes much busier." One popular song today is also called "A lonely man in crowds." Actually, engaging in social intercourse requires ability, while being alone involves the whole character.

These days, it is not easy to calm down totally and return to one's true self. Willpower, intellect and discipline are required. Einstein said: "It is not your working time but your spare time that determines the possibility of whether you will be successful or not." The "spare time" he referred to could be taken as "spending time by yourself."

Lonely life could be either dull, boring and tasteless or abundant, interesting and colorful,

depending on one's quality, ambition and inspiration.

Just as the body constantly requires energy, the mind and soul also demand never stopping inputs. However,information, processed and integrated (融入) into knowledge, thoughts and feelings, instead of bustle (忙碌) seems to be the right condition. Successful careers m all walks

of life worldwide have proved that "the soul grows in peace and talent is nurtured in loneliness".

In a sense, it may be reasonable to say that " Happiness tends to be shallow while loneliness involves depth".

Man, in fact, needs loneliness more than happy time, and only abundant loneliness can produce quality happiness.

（1）Which of the following can replace the underlined the word "boisterously" in paragraph l?

A. surprisingly

B. sadly

C. busily

D. peacefully

（2）What can we infer from the second paragraph?

A. Being alone marks people depressed.

B. Social intercourse improves our happiness.

C. One may feel lonely even when surrounded by people.

D. We should attend social intercourse to decrease our loneliness.

（3）What can we know from Einstein's words?

A. You should be successful if you spend all your time by yourself.

B. You should exercise more if you want to keep your minds healthy.

C. You will not become successful if you join in more social intercourse.

D. You will be more successful if you can make your lonely time meaningful.

（4）Which may be the best title for this passage?

A. Live on Your Own

B. Happiness and Loneliness

C. The Secret of Success

D. Practice Your Social Ability

【答案】（1）C

（2）C

（3）D

（4）B

【解析】【分析】本文是议论文。主要讨论了在现今社会中很多的社会往活动在进行中，

人们看似很幸福。然而，一切都掩盖不了人们在这些幸福场景背后倍感孤独的社会现象。（1）考查词意猜测题。根据第一段可知，如今，尤其是在中国，一切都似乎有利于社会交往，如朋友聚会、KTV、团体旅游、餐饮更紧，打牌和麻将，加上中式“过街组”。可以猜测

出下文：回到家中仍然忙着在微信上讨论。所以划线词boisterously的意思是“忙的”，故选C。

（2）考查推理判断题。根据第二段第一句，也是主题句However, these scenes cannot always ease a sense of loneliness.以及A lonely man in crowds.”可知，一个人就算被人包围着

也可能感到孤独。故选C。

（3）考查细节理解题。根据第三段Einstein said: “It is not your working time but your spare time that determines the possibility of whether you will be successful or not.”（爱因斯坦说：“不是你的工作时间，而是你的业余时间决定了你是否成功的可能性。）可知，如果你能让

寂寞的时间更有意义，你会更成功。故选D。

（4）考查标题判断题。本文主要讨论了在现今社会中很多的社会往活动在进行中，人们看似很幸福。然而，一切都掩盖不了人们在这些幸福场景背后倍感孤独的社会现象。所以最佳标题是B. Happiness and Loneliness，故选B.

【点评】寻找文章的主题句

了解文章主要论题的关键是找到全文的主题句。主题句通常在文章首段，但是也可能在文章的末段、在文章的某一段落，或者分散在文章的各个段落中。如果每个段落都有主题句，那么把各段落的主题句的中心思想集中起来，即为全文的主题句。

9．阅读理解

Rich countries are racing to dematerialise payments. They need to do more to prepare for the side-effects.

For the past 3,000 years, when people thought of money they thought of cash. Over the past decade, however, digital payments have taken off— tapping your plastic on a terminal or swiping a smartphone has become normal. Now this revolution is about to turn cash into an endangered species in some rich economies. That will make the economy more efficient—but it also causes new problems that could hold back the transition(转型).

Countries are removing cash at varying speeds. In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years. America is perhaps a decade behind. Outside the rich world, cash is still king. But even there its leading role is being challenged. In China digital payments rose from 4% of all payments in 2012 to 34% in 2017.

Cash is dying out because of two forces. One is demand— younger consumers want payment systems that plug easily into their digital lives. But equally important is that suppliers such as banks and tech firms (in developed markets) and telecoms companies (in emerging ones) are developing fast, easy-to-use payment technologies from which they can pull data and pocket fees. There is a high cost to running the infrastructure behind the cash economy—ATMs, vans carrying notes, tellers who accept coins. Most financial firms are keen to abandon it, or discourage old-fashioned customers with heavy fees.

In the main, the prospect of a cashless economy is excellent news. Cash is inefficient. When payments dematerialise, people and shops are less open to theft. It also creates a credit history, helping consumers borrow.

Yet set against these benefits are a couple of worries. Electronic payment systems may risk technical failures, power failure and cyber-attacks. In a cashless economy the poor, the elderly and country folk may be left behind. And a digital system could let governments watch over people's shopping habits and private multinationals exploit their personal data.

（1）Some rich countries are trying to .

A. dematerialize money

B. get rid of the side-effects of cash

C. make the economy more efficient by protecting endangered species

D. promote payment without paper money or coins

（2）In paragraph 3, several countries are mentioned to show .

A. the differences between developed and developing countries

B. that cash is still king across the world

C. digital payments are becoming a trend that cannot be stopped

D. China is developing faster that those developed countries in digital payment

（3）Cash is disappearing largely because .

A. younger consumers are short of money to live their digital lives

B. suppliers are trying to reduce costs and obtain money and data

C. the infrastructure is developing at a high speed in developed markets

D. financial firms want to abandon old-fashioned customers

（4）The author's attitude towards digitalized payment is .

A. favorable

B. negative

C. objective

D. indifferent

【答案】（1）D

（2）C

（3）B

（4）C

【解析】【分析】本文是一篇说明文，富裕国家正在减少现金支付,现金正在因为需求等原因消失。总的来说,无现金经济的未来是个好消息,但是对于电子支付人们也有一些担忧。（1）考查细节理解。根据第一段中的“Rich countries are racing to dematerialise payments.”可知, 富裕国家正竞相将支付非物质化；再根据第三段中的“In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years.”在过去的十年中,瑞典的人均零售现金交易数量下降了80％。结合上下文,可知某些富裕国家比如瑞典正在减少现金支付,推广不用纸币或硬币的支付方式,也就是电子支付方式。故选D。

（2）考查推理判断。根据第三段中的“In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years.”可知在过去的十年中,瑞典的人均零售现金交易数量下降了80％；再根据“In China digital payments rose from 4% of all payments in 2012 to 34% in 2017.”可知在中国,数字支付从2012年占所有支付的4％上升到2017年的34％。瑞典和中国的共同点是现金支付减少,电子支付比例上升,由此可推断作者提到瑞典和中国是为了说明数字支付正成为一种不可阻挡的趋势。故选C。

（3）考查推理判断。根据第四段中的“But equally important is that suppliers such as banks and tech firms (in developed markets)... Most financial firms are keen to abandon it, or discourage old-fashioned customers with heavy fees.”可知现金消失的一个重要原因就是诸如银行和科技公司（在发达市场）和电信公司（在新兴市场）之类的供应商正在开发快速,易于使用的支付技术,他们可以从中提取数据和小费。运行现金经济背后的基础架构需要付出高昂的成本,这些基础设施包括自动取款机,载有纸币的货车,接受硬币的出纳员。大多数金融公司都渴望放弃它,或者以高昂的费用劝阻老式客户。也就是供应商为了减少成本,获取数据和小费,开发了更便捷的支付方式,导致现金支付的减少。故选B。

（4）考查推理判断。纵观全文可知，,作者提到无现金支付即电子支付的好处,也提到电子支付引起的担忧,对待电子支付是客观的,故选C。

【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇科技类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，从而选出正确答案。

10．阅读理解

Learning, Fast and Deep

Over the past five years researchers in artificial intelligence have become the rock stars of the technology world. A branch of AI known as deep learning, which uses neural(神经的) networks to scan through large volumes of data looking for patterns, has proven so useful that skilled practitioners can command high six-figure salaries to build software for Amazon, Apple, Facebook and Google.

The standard route into these jobs has been a PhD in computer science from one of America's

top universities. Earning one takes years and requires a personality suited to academia, which is rare among more normal folk.

That is changing.

Last month fast.ai, a non-profit education organization based in San Francisco, kicked off the third year of its course in deep learning. Since its foundation it has attracted more than 100, 000 students around the globe from India to Nigeria. The course and others like it, come with a simple idea: there is no need to spend years obtaining a PhD in order to practise deep learning. Creating software that learns can be taught as a craft, not as a high intellectual pursuit to be undertaken only in an ivory tower. Fast. ai's course can be completed in just seven weeks.

To make it accessible to anyone who wants to learn how to build AI software is the aim of Jeremy Howard, who founded fast.ai with Rachel Thomas, a mathematician. He says school mathematics is sufficient. "No. Greek. Letters," Mr. Howard intones, pounding the table with his

fist for punctuation.

Some experts worry that this will serve only to create a flood of unreliable AI systems which

will be useless at best and dangerous at worst. In the earliest days of the Internet, only a select few nerds, namely computer holies with specific skills, could build applications. Not many people used them. Then the invention of the World Wide Web led to an explosion of web pages, both good and bad. But it was only by opening up to all that the Internet gave birth to online shopping, instant global communications and search. If Mr. Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind.

（1）What can we learn about deep learning?

A. It replaces artificial intelligence.

B. It attracts rock stars to practice.

C. It scans patterns for large companies.

D. It helps technicians to create software.

（2）Fast. ai is an organization that .

A. ensures one to obtain a PhD

B. teaches craft in ivory tower

C. offers a course in deep learning

D. requires weeks to apply

（3）The underlined words "No. Greek. Letters"in Paragraph 5 means doing fast.ai course is .

A. easy

B. difficult

C. interesting

D. boring

（4）It can be inferred from the last paragraph that .

A. it is quite reliable for anyone to grasp artificial intelligence

B. the Internet has brought forth a flood of useless AI systems

C. opening up to all leads to instant global search and online shopping

D. simplifying software development may result in unexpected outcomes

【答案】（1）D

（2）C

（3）A

（4）D

【解析】【分析】本文是一篇说明文，人工智能的深度学习被证明很有用，霍华德和数学家托马斯一起创办的非营利性教育机构致力于让深度学习变得简单。

（1）考查细节理解。根据第一段中的”A branch of AI known as deep learning, which uses neural networks to scan through large volumes of data looking for patterns…build software for Amazon, Apple, Facebook and Google.“可知AI技术的一个分支、运用神经网络处理大量数据并从中寻找模式的"深度学习"被证明非常有用，亚马逊、苹果、Facebook和谷歌愿意开出六位数高薪，聘请熟练的专业人员编写软件。这说明深度学习能帮助编写软件，故选D。（2）考查细节理解。根据第四段中的”Last month fast. ai, a non-profit education organization based in San Francisco, kicked off the third year of its course in deep learning.“可知。上月，位于旧金山的非营利性教育机构fast.ai 进入了它开办深度学习课程的第三年。也就是说fast. ai是一个提供深度学习课程的组织，故选C。

（3）考查句义猜测。根据五段中的”To make it accessible to anyone who wants to learn …He says school mathematics is sufficient.“可知让深度学习不再神秘是杰里米·霍华德的目标，为此，他和数学家雷切尔·托马斯一起创立了fast.ai，让任何想学习编写AI软件的人都能学习这门技术。霍华德说有中学数学知识就足够了。这说明fast.ai的课程很简单，仅需要中学数学知识。因此霍华德说"No. Greek. Letters”没有，希腊，字母“是想说fast, ai的深度学习课程很简单。故选A。

（4）考查推理判断。根据最后一段中的”If Mr Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind. “如果霍华德和其他人如愿以偿，那么让AI软件开发变得更容易将会催生出一批新的不同的果实。由此推断简化软件开发可能会导致意料之外的结果。故选D。
