【推荐1】In the Three-Body Problem books, Trisolarans, a type of alien, can dehydrate (脱水) their bodies. They can then ride out terrible environments and come back to life again hundreds of years later. Is it possible that humans could be like that as well?

Scientists have now made a new discovery by studying water bears. These microscopic organisms can live without water for decades, according to University of Tokyo biologist Takekazu Kunieda.

When water bears find themselves somewhere without water, they go into a form called a tun. In this form, there are no signs of life, and they can survive pretty much anything. Deep freezing, volcanic fire, the dark space… these tiny water bears just sleep it off and wake up once it’s safe again, said Science Alert.

But how do these little eight-legged water bears live without water? Scientists may be onto the answer now.

“It’s thought that as water leaves a cell (细胞), some kind of protein must help the cell keep its strength to avoid breaking apart,” said Kunieda. Now scientists have found proteins special to water bears. The proteins protect their cells against dehydration.

Scientists also put those proteins into human cells. They found these proteins can strengthen the human cell so that it won’t become smaller in size when losing water, said Science Alert.

With experiments using human cells showing successful results, Trisolarans might one day come to be a reality.

【推荐3】Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you.    1    

So how? The cars have sensors（感应器）all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems（卫星导航系统）are used so the car knows how to get where you want to go.     2    .Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.

Sound like your idea of heaven（天堂）? Sitting back, looking out of the windows and even watching a film or reading a book while ‘driving’ would be possible with this new technology. You wouldn’t have to worry about remembering directions to where you’re going.    3     they would obey the rules and have quicker action times when in dangerous situations.

    4    .Computers would have difficulties making ethical（道德的）decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly in the risk of   killing   car’s passengers? Moreover, I personally find driving fun 一I’d miss   driving a car myself.     5    . Should children, or drunk people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?

I’m not certain I’d want a driverless car 一 but it’s only a matter of time before they’ll become more affordable and popular on our roads.

A．However, there are many drawbacks of driverless cars.

B．Companies like Google and Tesla have been designing and testing these cars, and the technology is there.

C．What’s more, computers would also drive more safely than people .

D．All you have to do is type in the address!

E．The driverless car knows all the directions well.

F．There would also be many other decisions to be made .

【推荐2】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。

Children need time to stand and stare. They should be allowed to get bored so that they can develop their ability to be creative.

    1     However, research shows that it may hamper (妨碍) the development of their imagination, while boredom can give them opportunities to develop creativity.

Boredom often goes along with loneliness, but a writer named Meera Syal said boredom had helped her in developing her mind.     2     Having few things to do, Syal often talked with her neighbors. She also tried to do things like learning to bake cakes. “But importantly, I thought and wrote a lot, because I was bored,” Syal said. She kept a diary, filling her time with short stories and poems she made up.

Grace Perry, an artist, grew up in a family with little money. She enjoyed herself by making up stories, drawing pictures for her stories and reading many books in the library. Bored but free, she spent hours looking out of the window, watching the changing clouds and seasons.     3     She became creative, because she could think freely.

Usually, when children have nothing to do, they would turn on the TV, the computer, or the phone.     4     But they need to have time to think about their experiences through play or just watching the world around them.

    5     On the other hand, the TV or phone may cut short the thinking process. That can be harmful to the development of creativity. “For developing the ability to be creative,” Dr. Belton advised, “perhaps we need to stand and stare, and stay offline from time to time.”

A．Their time on these things has increased.

B．She told researchers about her childhood.

C．Most children feel bored about their school life.

D．She filled up her free time with what she liked.

E．It is this kind of thinking that can inspire the imagination.

F．Children are expected by their parents to be reading a textbook all the time.

【推荐3】In the United States, headmaster and teachers punish students in several ways. The teachers often writes to or calls the students’ parents. Sometimes students have to stay at school for an extra hour. If a student behaves(表现) very badly, the headmaster can suspend(使暂停上课) the student. The student can’t come to school one, two or three days. Mr. Green didn’t like to suspend students. When he suspended students, they were happy. “A three-day holiday!” they thought. One day, a boy named Robert was in Mr. Green’s office. The boy was not behaving well in class. Mr. Green phoned the boy’s parents. “If you come to school with your son, I won’t suspend him,” he said. The boy’s father came to school and went with his son to every class. Other students stared at(盯着看) the boy and his father. The boy was embarrassed. After that, he behaved better. He didn’t want his father to come to school again. Other students behaved better too. They thought, “I don’t want my parents to come to school!”

That year, about 60 parents came to school with children who didn’t behave well. The next year, only a few parents had to come to school. The students were behaving better.

【推荐1】① China has completed its BeiDou Navigation Satellite System, or BDS, becoming another one in the world with a global navigation network （全球导航网络）, and the other three are GPS of the US, GLONASS of Russia and Galileo of the European Union.

② As the name suggests, the global navigation satellite system provides navigation and location services 24 hours a day. From what we have kmown so far, building a good satellite system costs a lot. Besides, the other systerns have been set up. Why does China have a new one if there is nothing special?

③ The other three systems have 24 satellites in MEO（中轨道）. In addition to the 24 satellites, China’s new global navigation satellite system BeiDou-3 also has three satellites in GEO（地球静止同步轨道）and three in IGSO（倾斜地球同步轨道）. These six satellites are special because they have a fixed area of activity. This can improve BDS’accuracy （精准度） in China and the Asia-Pacific area to 5 meters, compared with a 10-meter accuracy in other areas.

④ BDS has another advantage-the short message service. It allows users to have a two-way communication. In areas not covered by communication signals, BDS can make the short message service work in areas without humans, such as deserts, forests, mountainous and polar areas. With this service, users who are in danger can tell the rescue team （救援队） their

location and condition.

⑤ As a county with the largest population in the world,its important for China to have its own global navigation satellite system to meet the needs of the country’s development.

⑥ In fact, BDS is also good business. According to the official report, China’s satellite industry has kept a 20% annual growth since 2012. And BDS contributes（贡献）about 80% of it. In addition, BDS has also created countless high-paying jobs. And with continuous improvement, it will have much more to offer in the future.

1. We can know that BDS is the ________ global navigation network in the world.

A．third

B．fourth

C．fifth

D．sixth

2. According to the passage, we can infer （推断） that __________.

A．GPS of the US and GLONASS of Russia have 25 satellites in MEO

B．BDS can make the short message service work in areas like deserts or forests

C．BDS might improve itself and have better influences in the future

D．European Union doesn’t need its own navigation satellite system
