A single dose(剂量) of an experimental vaccine(疫苗) can protect mice against the Zika(寨卡) virus, raising renewed hope of a vaccine for humans, say scientists. The US team say the results, published in Nature, are "striking" and should encourage research efforts.

Tests in humans could begin in months. But even if these go well, a licensed vaccine for widespread use to protect those at most risk -such as pregnant women -would still be years away, experts advise. Zika has been spreading across Central and South America and, most recently, Africa. More than 60 countries and territories now have continuing transmission(传播) of the disease, which is carried by mosquitoes. The virus causes serious birth damages during pregnancy and has been declared a global public health emergency.

Now, developing a vaccine for pregnant women to protect their unborn babies is an international research priority(优先事项). US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice – one based on bits of genetic(基因的) code from the virus and another that is an inactive (and therefore harmless) copy of Zika. Both worked well, protecting every mouse that was immunised against the virus. In comparison, all of the mice not given the vaccine caught Zika after they were exposed to it.

Researchers say they will push ahead with developing the needed virus vaccine. There are many existing vaccines for other disease that use this type of technology, while there are relatively few DNA-based vaccines. Of course, future tests will need to check the vaccine is safe and effective in humans, as well as how long the immunity might last.

（1）If the tests in humans go smoothly, .

A. a vaccine for use in the laboratory will be still be years away.

B. pregnant women in Africa will be the first to benefit from the vaccine.

C. a licensed vaccine will still not be accessible in a short term.

D. The Zika virus will cause less serious birth defects during pregnancy in months.

（2）Which of the following statements is NOT true?

A. many countries are actively involved in the research of the Zika vaccine.

B. US scientists have tested more than two types of Zika vaccine in mice.

C. None of the mice given the vaccine caught Zika.

D. It is still unknown whether the vaccine is safe and effective.

（3）Which can be the best title for the passage?

A. Zika vaccine 'works very well' in mice

B. Zika vaccine still has a long way to go

C. International researches into Zika have paid off

D. More attention has been paid to Zika vaccine

【答案】（1）C

（2）B

（3）A

A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them." These items could include weapons, chemicals, laptops and batteries for bombs, "the research team said on Tuesday.

Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天线)that could be fitted in existing Wi-Fi networks. The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干扰)caused by two factors of objects-the material and shape." Most dangerous objects such as weapons are usually metal or liquid, which have significant interference," researchers said.

When it was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can inspect bags or luggage without being an exposure to privacy.

It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This could have a great impact on protecting the public from dangerous objects," said Yingying Chen, a co-author of the study," There's a growing need for that now. In large public areas, it's hard to set up expensive screening equipment like what's in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”

The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference

on Communications and Network Security, is now published online." Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes," researchers said.

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

4．犇犇阅读理解

In our twenties, we find it funny when we can't remember our neighbor's cat's name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it "brain freeze". In our forties, we laugh it off as a" senior moment" and follow up with one of these old age jokes. But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, "Am I losing it？"Or worse, "Is this a sign of Alzheimer's disease （老年痴呆症）？"

Well, don't worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease（AD）. The researchers in a new study show that it's not forgetfulness but not being aware that we're forgetful that we should fear.

The researchers began with the assumption that one common feature of Alzheimer's dis-ease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with" mild cognitive（认知的）damage" will progress to full-on AD. For the study, "mild cognitive damage" was defined as someone whose mental state was considered healthy but who had either complained of memory loss or had suffered objective memory loss.

The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12-year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness.

Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.

（1）What can be implied from paragraph 1？

A. People can be forgetful at different ages.

B. The memory of the young is better than the old.

C. Old people are most afraid of getting Alzheimer's disease.

D. It's a rare phenomenon when young people forget something.

（2）What statement does the researchers in the new study agree with?

A. Being aware all the time is a fearful thing.

B. Illness awareness has nothing to do with Alzheimer's disease.

C. Recognizing forgetfulness doesn't mean developing Alzheimer's disease.

D. Realizing forgetfulness must be a sign of developing Alzheimer's disease.

（3）What can be a sign of developing Alzheimer's disease?

A. Realizing others' forgetfulness.

B. Reduced uptake of glucose.

C. Having higher intake of glucose.

D. Expected increase in brain function.

（4）From which is the text probably taken?

A. Science fiction.

B. A chemistry book.

C. A science research.

D. A health brochure.

【答案】（1）A

（2）C

（3）B

In our thirties, we jokingly call it ‘brain freeze’In our forties, we laugh it off as a‘senior moment’ and follow up with one of these old age jokes. But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful.”在二十多岁的时候，当我们记不起邻居的猫的名字或是主演一部著名电影的英俊演员时，我们觉得很有趣。在三十多岁的时候，我们开玩笑地称它为“大脑冻结”，在四十多岁的时候，我们把它当作“老年时期”来嘲笑，然后继续讲这些老年笑话。但现实是，有这样的时候，健忘不再有趣，而且看起来有点可怕，可推知选A。

（2）考查细节理解。根据第二段中的“ The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease（AD）”承认自己的健忘也许是一个很好的迹象，至少从你患老年痴呆症,的可能性来看，可知选C。

（3）考查细节理解。根据第四段中的“ It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD.”这是一个患有老年痴呆症降低了脑功能的客观标志。正如所料，老年痴呆症患者的葡萄糖吸收降低，故选B。

（4）考查推理判断。纵观全文可知，是一项科学研究，介绍了如何预测你的记忆丧失是否是老年痴呆症, 故选C。

5．犇犇阅读理解

Wolves strike fear into the hearts of many species, humans included. Our fear of them has brought them to the edge of dying out, as we have cruelly killed them as competitors and trouble-makers. But researchers are discovering that the very fear they put into prey（被捕食者）species is exactly what helps make ecosystems（生态）healthy.

Yellowstone National Park is a typical example of just how wolves can help repair an ecosystem. An October 2018 study analyzed 40 years of research on large animals inside the park.

"Yellowstone has benefited from the reintroduction of wolves in ways that we did not anticipate, especially the complexity of biological interactions（互动）in the park," explained Mark Boyce, a professor in the Department of Biological Sciences." We were really surprised at that and we'd never have seen these responses if the park hadn't adopted ecological-process management—allowing natural ecological processes to take place with least human intervention."

After the wolves were re-introduced at Yellowstone, willow and cottonwood trees increased in number. The population of bears and bison also rose and what was once a ruling deer-wolf interaction is now more diverse.

To learn more about just how wolves are beneficial, a short documentary from Quest explains how the presence of wolves influences the behavior of deer, which eventually makes entire ecosystems more biologically diverse and healthy. In this documentary, biologist Aaron Wirsing explored why wolves and other top predators （捕食者）were needed for diverse ecosystems to develop. Using a simple video camera, Wirsing is gaining a unique view point on predator-prey relationships and changing the way we think about wolves.

The research is one more piece of evidence for why protecting these top predators is important not just for wolves as a species, but for hundreds of species at every level of an ecosystem. The fear they bring along may be the very angle that helps save them from dying out.

（1）What does the underlined word "anticipate" in paragraph 3 probably mean?

A. Expect.

B. Understand.

C. Notice.

D. Accept.

（2）For what purpose was a documentary made?

A. To introduce how wolves behave in the wild.

B. To show how wolves benefit from ecosystems.

C. To record how Aaron Wirsing observed wolves.

D. To study what good wolves can do to ecosystems.

（3）What is the significance of the research?

A. It proves wolves feed on hundreds of species.

B. It helps prove the importance of protecting wolves.

C. It shows the complex relationships between species.

D. It provides evidence that wolves are endangered animals.

（4）What is the main idea of the passage?

A. The fear of wolves is beneficial to ecosystems.

B. The fear of wolves put them in danger of disappearing.

C. Yellowstone National Park owes its healthy ecosystems to wolves.

D. The introduction of wolves in Yellowstone National Park is a success.

【答案】（1）A

（2）D

（3）B

6．阅读理解

Delhi has been the centre of a succession of mighty empires and powerful kingdoms in India. Numerous ruins scattered throughout the territory offer a constant reminder of the area's history, which makes the city always be a fascinating place for tourists.

With the development of the city and more and more people moving, the city has expanded several times in size. That is why it is called New Delhi. New Delhi, a city with a population of over 20 million people, has its newest problem: never before has this city met with the worst air problem.

Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has become an annual public-health emergency despite government vows to solve the problem.

Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.

New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coal-based power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states. Fireworks and firecrackers to celebrate the Hindu festival of Diwali then arrives, leaving Delhi the world's most polluted city. The city's air quality index, which measures a mix of dangerous pollutants, registered an average score of 494 Sunday. That is the highest 24-hour average since Nov. 6, 2016, when it hit 497, according to data measured by the Central Pollution Control Board.

（1）Which of the following is NOT true?

A.Diwali is one of the most important festivals in India.

B.The government did little to protect its citizens against the serious pollution.

C.Such a serious air pollution in New Delhi appears on a regular basis.

（2）Who may not complain about the serious air pollution?

A.The parents whose children have to stay at home.

B.The pilots whose planes have been diverted or delayed.

C.The manufacturers who produce antipollution masks.

D.The officials who have to work out of their offices.

（3）Which of the following phrases can replace the underlined word in paragraph 5?

A.Sent out.

B.Sent up.

C.Sent in.

D.Sent on.

（4）The title of the passage should be .

【解析】【分析】本文是一篇说明文，随着城市的发展和越来越多的人口流动，城市规模的扩大，印度的新德里成为世界上污染最严重的城市。虽然政府发誓解决污染问题，但由于污染严重，整个新德里处于危险的污染中，人们必须戴防污口罩，冬天天气寒冷污染物成雾霾，成为世界是污染最严重的城市。

（1）考查推理判断。根据第三段“Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has become an annual public-health emergency

despite government vows to solve the problem.”印度首都的空气污染飙升至多年来最严重的水平，笼罩着这座城市的浓雾已成为年度公共卫生紧急事件，尽管政府誓言要解决这个问题；第五段“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coal-based power plants, swirling dust ..., leaving Delhi the world's most polluted city.” 新德里每年都会被污染吞没，随着天气变冷，汽车和以煤为基础的发电厂排放的污染物、建筑工地和道路上飘动的灰尘，以及邻国农作物秸秆燃烧产生的烟雾，都会形成浓雾。庆祝印度排灯节的烟花爆竹随后到达，使德里现在成为世界上污染最严重的城市；以及第四段中的“Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.” 在学校、学院、医院和市场上分发了数以百万计的防污口罩。可知，政府尽管发誓解决这种污染，但情况不仅没有改变，反而更加严重，使得人们必须佩戴防毒口罩。由此可判断出政府几乎没有保护其公民免受严重污染。故选B。

（2）考查推理判断。根据第四段“Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.” 周末期间，由于能见度低，数百架航班被迫改道、延误和取消，学校和办公室周一关闭，官员们紧急采取措施，试图扭转不断恶化的空气质量。学校、大学、医院和市场分发了数百万个防污染口罩。由此可知，由于污染严重，学校、大学、医院和市场分发了数百万个防污染口罩。所以生产防污染口罩的厂家要加大生产，是不会抱怨的，故选C。

（3）考查词义猜测。根据第五段中的“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coal-based power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states.”本句是说新德里每年都笼罩在污染中。因为天气变冷，从汽车和以煤为基础的发电厂“emitted”的污染物形成了厚厚的雾霾。根据常识可知，汽车和用煤发电的发电厂会“排放或释放”污染物的。由此可判断“emitted”是排放的意思。故选A。

（4）考查主旨大意。本文叙述了随着城市的发展和越来越多的人口流动，城市规模的扩大，印度的新德里成为世界上污染最严重的城市。虽然政府发誓解决污染问题，但周末的能见度低，数百架航班在周末改道、延误和取消，学校和办公室周一关闭，人们必须戴防污口罩，可知，新德里被严重的污染所笼罩。故选B。

7．阅读理解

According to a team of researchers, an animal's ability to perceive(感知)time is linked to their pace of life.

"Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures." commented lead author Kevin Healy from Trinity College Dublin.

The study was done with a variety of animals using phenomenon based on the maximum

speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.

One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve, "which allows them to avoid being hit.

Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."

In comparison, the tiger beetle(虎甲虫)runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(猎物)position.

Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.

（1）What is the research mentioned in the passage mainly about？

A. Pace of life of animals.

B. Impressive abilities of animals.

C. Lifetime of small animals.

D. Time perception of animals.

（2）What does Kevin Healy's comment mean in Para.2？

A. The survival of fast moving animals relies on their ability to perceive time.

B. Animals with quicker pace of life have better perception of time.

C. The ability of animals to perceive time depends on their high moving speed.

D. Animals with poor ability of time perception have a shorter life.

（3）Why can houseflies avoid being hit?

A. They can think very deeply before they act.

B. They can process the information as quickly as they receive it.

C. They can fly much faster than their eyes can keep up.

D. They can send information to brain more quickly than to their eyes.

（4）What will a tiger beetle have to do to catch a moving prey?

A. Slow down to gain its time perception.

B. Prevent itself from becoming blind.

C. Stop occasionally to spot the prey again.

D. Try to run as fast as it can.

【答案】（1）D

（2）A

（3）B

（4）C

【解析】【分析】本文是一篇说明文，介绍了对动物时间感知的研究。

（1）考查细节理解。根据第一段中的“According to a team of researchers，an animal's ability to perceive（感知）time is linked to their pace of life.”可知，据一组研究人员称，动物感知时间的能力与它们的生活节奏有关，由此可知，文中提到的这个研究是关于动物的时间感知的，故选D。

（2）考查推理判断。根据第二段中的“the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for

fast moving creatures.”可知，对于能快速移动的动物而言，在极短的时间内感知时间的能力可能是生与死的区别，由此可知，Kevin Healy说的意思是快速移动的动物的生存依赖于它们对时间的感知能力，故选A。

（3）考查细节理解。根据第四段中的“The research showed flies ‘observe motion in a shorter time than our own eyes can achieve，’which allows them to avoid being hit.”可知，家蝇观察物体运动的时间比我们人眼所能达到的时间要短，这使得它们能够避免被击中；再结合第五段中的“but they can make good decisions very quickly.”可知，它们可以很快做出好的决定，也就是说它们可以尽快处理收到的信息，故选B。

（4）考查细节理解。根据倒数第二段中的“the tiger beetle（虎甲虫）runs faster than its eyes can keep up，basically becoming blind，which requires it to stop periodically to re-evaluate its prey's（猎物）position”可知，虎甲虫的移动比眼睛快，基本上是盲目的，这就要求它不时地停下来，重新评估猎物的位置，由此可知，为了抓住移动的猎物，虎甲虫需要不时地停下来确定猎物的位置，故选C。

Plants are boring. They just sit there photosynthesizing (光合作用) while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution (协同进化) started with ants feeding on plants and plants evolving ant-friendly features.

Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mаmmаl?. Тhе?е ?nсludе hollow thorns that аnt? will live ?n??dе, or ехtra nесtаr (琼浆) оn lеаvе? or stems for the ants to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away, eat the food packet, and leave the seed—often in a nutrient-rich area where it'll grow better, and since it's farther away from its parent, they won't have to compete for resources.

But scientists weren't sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chicken-and-egg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.

The history of ants and plants evolving together goes back to the time of the dinosaurs, and it's not easy to tell from fossils who fired the first shot. However, it is a question of little significance. Scientists say their study maters because it provides a look at how these widespread and complex interactions evolved.

9．阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

Fairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.

The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called "Quixote" (堂吉诃德). It collects story plots from the Internet and then uses those stories to teach robots how to behave.

The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives (指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robot will learn the moral way to behave on that occasion.

Quixote would work best on a robot that has a very limited function. It's a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.

（1）What function do fairy tales perform in the robots?

A. They entertain robots.

B. They highlight dangers.

C. They make robots more intelligent.

D. They enable robots to behave morally.

（2）What is "Quixote" in the text?

A. A punishment system

B. A character in literature

C. A big name in technology

D. A software educating robots.

（3）What does the designer expect robot to do in the experiment?

A. To take advantage of its privilege.

B. To finish the task most efficiently.

C. To perform in a good mannered way.

D. To be rewarded by the storekeeper!

（4）Which of the follow can best express the author's opinion?

A. Robots will definitely have more functions.

B. Robots with human's emotions are perfect.

C. Training robots to be socially acceptable is necessary.

D. The development of robots is still in a baby step.

【答案】（1）D

（2）D

（3）C

（4）C

10．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。

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 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, 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 One racing car.

The Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute that would be used, if there should be an emergency. "It starts to work at very low altitude and actually saves both 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）Peter Coker uses the example of Formula 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 author's 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）B
