【英语】阅读理解(科普环保)练习及解析
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
【解析】【分析】本文是一篇说明文，随着越来越多的机器人具有人性化，它们承担越来越多样化的专业和日常任务，人们如何看待他们，如何对待他们的问题变的迫在眉睫。

（1）考查细节理解。

根据第一段中的“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.”可知，随着越来越多的机器装备了最新的人工智能，承担着越来越多的专业和日常任务，人们如何看待它们以及如何对待它们的问题变得越来越紧迫。

故选B。

（2）考查细节理解。

根据第三段中的“According to Sari Nijs sen, the study set out to answer the following question:‘ Under what circumstances would adults be willing to sacrifice robots to save human lives?’"可知，在这项研究中，参与者可能必须决定何时牺牲机器人。

故选A。

（3）考查推理判断。

根据最后一段中的"‘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."可知，Paulus认为让机器人人性化的尝试不应该走得太远，可以推断出，Paulus认为过多地人性化机器人可能是不合适的。

故选B。

（4）考查主旨大意。

根据第四段中的“The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it.”及全文内容可知，文章主要叙述了随着越来越多的机器人具有人性化，参与者就可能越不会牺牲机器人。

【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，是一篇科教类阅读，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。

2．犇犇Choose the one that fits best according to the information given in the passage you have just read.
While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭气) too.
Vulture (秃鸳)
Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry.
When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.
Opossum (负鼠)
In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.
Hoatzin (磨雉)
Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink bird
Millipedes (千足虫)
Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.
Sea Hare (海兔)
The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.
Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.
（1）The sea hare defends itself from predators by ________.
A. becoming plain in taste at the discovery of a predator
B. giving out purple ink to make itself invisible to predators
C. releasing substance to make predators unable to smell it
D. giving off smelly gas to try to drive predators away
（2）Which of the following statements is TRUE according to the passage?
A. The vulture carries bacteria so that predators dare not get close to it.
B. The opossum fakes its death to avoid being targeted by predators.
C. The hoatzin eats cow shit so that it is nick-named as "stink bird".
D. The gas released by millipede was basically harmless.
（3）The species that enjoys more than one defense mechanism is ________.
A. vulture
B. opossum
C. millipede
D. sea hare
【答案】（1）C
（2）B
（3）C
【解析】【分析】本文是一篇说明文，介绍了一些野生动物是如何进行自身防御的。

（1）考查细节理解。

根据 Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substan ce which makes food less palatable to predators.”可知，海兔身上散发出黏糊糊的紫色墨水，这种物质使得捕食者对食物不那么感兴趣，从而保护自己免受捕食者的伤害。

故选C。

（2）考查细节理解。

根据 Opossum (负鼠)部分中的“In order to become ‘dead’, they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere.”可知，负鼠假装死亡，让捕食者在其他地方找到更新鲜的食物，以避免成为捕食者的目标。

故选B。

（3）考查推理判断。

根据Millipedes (千足虫)部分中的“Their major defense is to c url up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足虫主要防守是蜷成一团。

然而，它们也会释放出有害的眼睛，并在攻击者身上留下可怕的气味。

从而可以推断出，千足虫是拥有多种防御机制的物种。

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，是一篇科普类阅读，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。

3．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。

The clock always seems to be ticking rather too fast in the doctor's office and the queue of patients outside the door seems to be pressing rather too hard. Some say it's high time for the model of short, sharp one-to-one appointments to give way to shared medical appointments (SMAs共享医疗预约).
SMAs are doctor-patient visits in which a group of patients receive patient education and counseling (咨询), physical examination and medical support in a group setting. Typically SMAs are designed to have one or more doctors attend to a group of patients who share a common illness or medical condition. In contrast to one-to-one visits, SMAS provide a longer appointment time-frame as well as the opportunity for patients to have improved access to their physicians and meanwhile pick up additional information and support from peers.
However, doctors who have pioneered the shared appointment approach report that there are significant challenges involved. Dr. Sumego, director of shared medical appointments, Cleveland Clinic, identifies culture change as the most significant challenge. Physicians and nurses are trained in a model of personal service and privacy; the SMA approach is a fundamental challenge to those fixed ideas. They need shared goals and a way of testing the innovation against agreed standards. Dr. Sumego says, "The physicians may be worried about the possible chaos and efficiencies that are marketed. They also have to make the patients understand what their appointment is, and what the expectation is."
"So, if an organization was looking to start shared medical appointments, I would advise them to start the buy-in from a few champion physicians, develop the work-flow and develop some experience. Provide some support behind what that best practice should look like. Create some standards so that, as the concept spreads, you can employ that experience to start the next
shared medical appointments and the next."
（1）What is the purpose of the SMA approach?
A. To improve medical service.
B. To promote doctors' reputation.
C. To conduct medical research.
D. To meet patients' expectation.
（2）According to Dr. Sumego, what prevents the SMA approach from being widely adopted?
A. Personal service.
B. Fixed ideas.
C. Lack of equipment.
D. Shared goals.
（3）What can the underlined "buy-in" in Paragraph 4 be replaced by?
A. practice
B. organization
C. purchase
D. support
（4）What can be learned about the SMA approach in the last paragraph?
A. It is currently being questioned.
B. It is impractical in some areas.
C. It will enjoy wide popularity soon.
D. It should be carried out step by step.
【答案】（1）A
（2）B
（3）A
（4）D
【解析】【分析】本文是一篇说明文，介绍了SMAs (共享医疗预约) 模式，以及这种模式
面临的挑战。

（1）考查推理判断。

根据第二段中的“In contrast to one-to-one visits, SMA provide a longer appointment time-frame as well as the opportunity for patients to have improved access to their physicians and meanwhile pick up additional information and support from peers.”可知SMAs模
式为患者提供了更长的预约时间，也为患者提供了更好地与医生接触的机会，同时还能从
同行那里获得额外的信息和支持。

这说明SAMs的出现是为患者提供更好的医疗服务。

故
选A。

（2）考查推理判断。

根据第三段中的“Dr. Sumego, director of shared medical appointments, Cle veland Clinic, …… personal service and privacy; the SMA approach is a fundamental challenge to those fixed ideas.”可知Dr. Sumego认为，文化转变是最大的挑战。

医生和护士接受的是
针对个人服务和隐私的培训; SMAs方法是对这些固定想法的根本挑战。

也就是说，改变这
些已经固定的想法是一种挑战，所以这些固定的想法会阻碍SMAs模式的推广，故选B。

（3）考查词义猜测。

根据最后一段中的“if an organization was looking to start shared medical appointments，I would advise them to start the buy-in from a few champion physicians”
可知如果一个组织要寻求共享医疗模式的话，Dr. Sumego建议他们从一些优秀的医师开始
他们的buy-in，根据语境，故选A。

（4）考查推理判断。

根据最后一段中的“So, if an organization was looking t o start shared medical appointments, I would advise them to start the buy-in from a few champion physicians, develop the… appointments and the next.”可知如果一个组织要开始SMAs，Dr. Sumego建议
他们从一些优秀的医师开始，开发一些流程，积累一些经验。

制定一些标准，以便随着概
念的推广，他们可以利用这种经验开始下一次共享医疗预约然后将下次的经验用到下下次。

这说明SMAs的实施需要一步一步来，不会一步到位。

故选D。

【点评】本题考点涉及词义猜测和推理判断两个题型的考查，是一篇介绍类阅读，要求考生根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。

4．犇犇阅读理解
Kaitlin Woolley and Ayelet Fishbach report in Psychological Science that a meal taken "family-style" from a central plate can greatly improve the outcome of later negotiations.
Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of competition. However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.
For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began.
The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（13.2 rounds）. A similar experiment was conducted with 104
participants and Goldfish crackers（饼干）, this time negotiating an airline's route prices. The results were much the same, with the food-sharers negotiating successfully 63. 3%of the time and those who did not share doing so 42. 9%of the time.
（1）What does the "family-style" meal in the report refer to？
A. A meal taken at home.
B. A meal shared with others.
C. A meal consumed by oneself.
D. A meal taken in a family atmosphere.
（2）For what purpose did the researchers carry out the present experiments?
A. To show the way food is served.
B. To prove sharing food increases competition.
C. To confirm sharing food can promote cooperation.
D. To find out whether sharing food can get people close emotionally.
（3）Why were participants asked to eat up the snack before the game?
A. To add to their energy.
B. To reward them for their participation.
C. To hide the intention of the experiment.
D. To avoid the distraction during the game.
【答案】（1）B
（2）C
（3）C
【解析】【分析】本文是一篇说明文，介绍了外交宴席的心理学，研究表明，从中间菜采取的“家庭式”餐，可以大大改善后续谈判的结果。

（1）考查细节理解。

根据第二段中的“They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of competition. However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result.”他们形成了一套理论，认为一方面，与他人一起吃饭可能表明粮食短缺，并加强了竞争的概念。

然而，他们还推断，这种方式可能会导致人们更加了解他人的需求，从而推动合作性的行为。

可知family-style指的是与别人一起用餐，故选B。

（2）考查细节理解。

根据第二段中的“However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.”然而，他们还推断，这种方式可能会导致人们更加了解他人的需求，从而推动合作性的行为。

出于好奇心，他们做了一系列实验。

可知选C。

（3）考查细节理解。

根据第三段中的“As a cover for the experiment, all particip ants were told this snack was to be consumed before the game began.”作为实验的掩护，所有受试者都得告在游戏开始前就要吃完这些零食。

可知选C。

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

（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。

6．阅读理解
Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you're being eaten alive within minutes of stepping outdoors.
If this is you, you're not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes' mouths water?
A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can't tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆虫学) at the University of Florida in the US, told NBC it's not complicated. "The two most important reasons a mosquito is attracted to you have to do with sight and smell." Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻击对象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That's why you commonly find them in crowded streets and parks.
Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, "Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (浓度)."
As a result, people who simply exhale (呼出) more of the gas over time –generally, larger people – have been shown to attract more mosquitoes than others. "This is why kids don't get bitten as much ... as adults," US professor Ted Rosen told Science Alert.
This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren't pregnant.
In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting
mosquitoes.
According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (视觉), people wearing dark colors are more likely to become targets.
Being bitten by mosquitoes is annoying, but don't worry. Some simple tips can help ward them off. Scientists recommend that we use insect repellent (驱虫剂) and wear light-colored clothing.（1）How do mosquitoes locate their targets, according to the article?
A.By seeking out bright clothes.
B.By identifying different blood types.
C.By sensing an increase of carbon dioxide.
D.By following bigger crowds.
（2）Why are pregnant women more likely to be bitten by mosquitoes?
A.Their larger size helps mosquitoes to see them.
B.They breathe out more CO2.
C.They are more likely to sweat.
D.Their body temperatures are higher.
（3）How does the article advise you to avoid mosquitoes?
A.Exercise regularly.
B.Wear light-colored clothing.
C.Keep your skin dry and clean.
D.Stay indoors in the evening.
（4）What's the article mainly about?
A.A new finding about mosquitoes.
B.How people can avoid mosquito bites.
C.A popular myth about mosquitoes.
D.Why some people are more attractive to mosquitoes than others.
【答案】（1）C
（2）B
（3）B
（4）D
【解析】【分析】本文是一篇说明文，介绍了为什么有些人可以整个夏天坐在户外乘凉却不被蚊子叮咬，而有些人一出门就好像要被蚊子吃掉一样。

（1）考查细节理解。

根据第四段中的“While flying along, they use their sense of smell to find possible targets. They find victims by smelling the carbon dioxide (CO2) breathed out by humans and animals. ”飞的时候，它们用嗅觉发现目标。

它们通过闻人和动物呼出的二氧化碳来锁定目标；以及第五段中的“Mosquitoes start ori enting themselves to carbon dioxide and keep flying upwind as they sense higher concentrations”蚊子开始飞向有二氧化碳的地方，当它们感知到高浓度的二氧化碳时，就保持逆流飞行，可知，蚊子通过感知二氧化碳的增加来锁定目标。

故选C。

（2）考查细节理解。

根据第七段“This love for CO2 can also put pregnant women at increased
risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren't pregnant.”对二氧化碳的喜欢使得孕妇很容易被蚊子咬，因为她们比正常相同年龄，相同体型的人呼出多余21%的二氧化碳，可知，孕妇呼出更多的二氧化碳，所以更招蚊子咬。

故选B。

（3）考查细节理解。

根据最后一段中的“Scientists recommend that we use insect repellent and wear light-colored clothing.”科学家建议我们使用驱虫剂或者穿浅颜色的衣服。

可知，文章建议我们可以通过穿浅色衣服来避免蚊子叮咬。

故选B。

（4）考查主旨大意。

根据第二段中的“According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoe s' mouths water?”根据Smithsonian杂志，世界上大约20%的人容易招蚊子咬。

为什么这些人非常吸引蚊子呢？可知，本文探讨的话题是：为什么一些人比其他人更容易招蚊子。

故选D。

7．阅读理解
E-Sports, short for electronic sports, is one of the growing industries in the world, with prizes totaling around $25 million up for grabs in some tournaments. E-Sports are professional multiplayer video game competitions. Any video game with a strong competitive element is considered e-Sports. The competition models itself after traditional professional sports in several ways: it uses corresponding tournament formats, involves player contracts, and is governed by regulations. The athletes who compete in e-Sports competitions are gamers．
The history of e-Sports dates back to 1972 when some Stanford University students competed in the Intergalactic Space War Olympics for the opportunity to win a one-year subscription to the Rolling Stone Magazine. E-Sports pretty much continued on the rather quiet path until the 80s when competitions like the Space Invaders Championship shot them to the spotlight. 2002 marked the beginning of a new era for the sport and laid the foundation for what e-Sports would become thanks to the release of the Xbox live, which brought online play to consoles. Halo Ⅱbecame the first game to be shown on national television for Major League Gaming in 2004, paving the way for e-Sports to become a global phenomenon.
Today, e-Sports are growing at a rapid pace thanks to advance in technology and the arrival of streaming services like Twitch which have exposed video game competitions to a new audience due to their extensive reach.
To understand how much impact Twitch has made, data from gaming analyst group Newzoo show that e-Sports global audience increased 43 percent from 204 million to 292 million between 2014 and 2016. Interestingly, this coincides (一致) with Amazon's acquisition of Twitch in 2014 and its effort to make the competition a spectator sport.
（1）What do we know about e-Sports?
A. They are strongly competitive.
B. They spread worldwide overnight.
C. They totally differ from traditional ones.
D. The athletes in the sports are programmers.
（2）What is the main idea of Paragraph 2?
A. The origin of e-Sports.
B. The variety of e-Sports.
C. The advantages of e-Sports.
D. The development of e-Sports.
（3）How does the author feel about e-Sport's future?
A. Doubtful.
B. Uncertain.
C. Hopeful.
D. Worried.
（4）What is the purpose of quoting data in the last paragraph?
A. To introduce Newzoo.
B. To conduct a research.
C. To show the influence of Twitch.
D. To arouse the audience's interest.
【答案】（1）A
（2）D
（3）C
（4）C
【解析】【分析】本文是一篇说明文,介绍了什么是电子竞技以及它的发展。

（1）考查细节理解。

根据第一段中的"E-Sports are professional multiplayer video game competitions. Any video game with a strong competitive element is considered e-Sports."可知,电子竞技是一种专业的多人视频游戏竞赛,任何具有强烈竞争元素的电子游戏都被认为是电子竞技,也就是说电子竞技具有很强的竞争性,故选A。

（2）考查段落大意。

根据第二段中的"The history of e-Sports dates back to 1972","E-Sports pretty much continued on the rather quiet path until the 80s","2002 marked the beginning of a new era for the sport"及"Halo Ⅱ became the first game to be shown on national television for Major League Gaming in 2004, paving the way for e-Sports to become a global phenomenon."等细节可知,本段以时间为顺序介绍了电子竞技的发展,故选D。

（3）考查推理判断。

根据倒数第二段可知，如今,由于技术的进步和像Twitch这样的流媒体服务的到来,电子竞技正在快速发展,由于Twitch的覆盖面广,它已经将电子游戏竞赛展示给了新的观众,特别是"growing at a rapid pace"表明了作者对电子竞技的未来充满希望,故选C。

（4）考查推理判断。

根据最后一段中的"To understand how much impact Twitch has made, data from gaming analyst group Newzoo show that e-Sports global audience increased 43 percent from 204 million to 292 million between 2014 and 2016."可知,为了了解Twitch产生了多大的影响,游戏分析机构Newzoo的数据显示,从2014年到2016年,全球电子竞技的观众数量增长了43%,从 2.04亿增加到 2.92亿,由此可知最后一段引用的数据就是为了表明Twitch产生的影响,故选C。

【点评】本题考点涉及细节理解，推理判断和段落大意三个题型的考查，是一篇科普类阅读，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。
