Since this autumn the British universities 1.have received (receive) almost 20, 000 applications from Chinese students.

Banksy is known 6.for being mysterious and unpredictable. No one knows his real name, 7.but his paintings are everywhere across the UK. He always plays hoaxes (恶作剧) on the art world. 5 People believe this is just another example of Banksy 8.playing (play) a trick. They think he is against the commercialization (商品化) of art. However, the 9.funny (fun) part is that this hoax might have made the painting more valuable. “(The price is) possibly as high as being worth 2 million (about 18.2 million yuan) plus,” Joey Syer, 10.founder (found) of art website MyArtB, told the Guardian. 提示词提示词答案答案考点考点 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 练习练习 5: I wanted to buy a pair of sports shoes for a long time.

Thousands of people were involved in a survey carried out last month, and 78% of 2.them (they) said they would still support the smoking ban. It is now much more pleasant 3.to go (go) into a pub or a restaurant. Before that, pubs were filled with smoke, 4.which made you cough and your hair and clothes smelly.

To be honest, I was scared when he first approached me. I thought to 5.myself (I), “There is a very good chance that he may rob (抢劫) me.” He seemed to have sensed my 8 discomfort so he tried to reduce my 6.anxiety (anxious) by introducing himself. His act of kindness made me feel ashamed to have questioned his intentions (意图). 7.It was really kind of him to stop to help a perfect stranger like me, especially in such terrible weather. Thus, after the tire was fitted, I asked how much I owed him. I wanted to pay him back. 8.Surprisingly (surprising), he did not take my offer but rather told me to pass the act of kindness forward and help more people 9.who are in need.

During normal times, Mr. Zhang, 32, is a taxi driver in this Chinese city at the epicenter of the outbreak. 3.But after the local government abruptly locked down the city late last month, Mr. Zhang became one of the thousands of people who have volunteered to help ease the transportation problems. Most of his passengers are poor, 4.elderly (elder) residents who dont have children or 5. whose family is outside Wuhan and cant come home because of the quarantine (隔离). “Its heartbreaking,” he says. “There is no one to take care of 6.them (they) .” The free rides 7.are arranged (arrange) by neighborhood committees, which typically serve as a go- between for residents and the local government. In the current crisis, those committees are in charge of allocating community 8.resources (resource) and helping coordinate with hospitals. Like other drivers, Mr. Zhang doesnt get 9.paid (pay).

When the train 3.got (get) close to Tibet,I had a headache. Then I found 4.it difficult to breathe and felt very tired. I knew that all my 5.symptoms (symptom) were called altitude(海拔) sickness. And it took me a few hours to get used to it. Tibet, 6.known (know) as the “Roof of the World”, has 7.a great many world-famous places of interest, including the model of Tibetan architecture, Potala Palace and Mount Everest. So when I felt a little 8.better (well), I couldnt wait to head towards them.

Nearly two decades have passed since China launched the first Beidou satellite in 2000. Since then, more Beidou satellites have been sent into orbit, 1.forming (form) the Beidou Navigation Satellite System (BDS). In late 2012, BDS 2.began (begin) providing services to people in China and other parts of the Asia- Pacific region. At the end of 2018, it started to provide global services. Now with two more Beidou satellites 3.launched (launch) on Dec 16, 2019, BDS has 53 satellites in orbit. It 4.is expected (expect) to greatly improve the systems ability to serve 5.users (user) worldwide. Although a satellite-based navigation system needs only 24 satellites to run 6.properly (proper), having 53 allows for better coverage. This is 7.how it works: a signal receiver on Earth measures its distance from at least three satellites by recording the amount of time it takes 8.to receive (receive) their signals. Then it can calculate its location. With so many satellites, BDS can provide 9.a more accurate calculation. While GPS provides meter-level positioning accuracy, BDS reduces the error 10.to centimeters.This service is especially useful for land surveying, mapping, agriculture and automated driving. Future plans call for a smarter and more accessible system with Beidou at its core, to come online by 13 2035. By then, we can probably say that Rome has finally been built. 提示词提示词答案答案考点考点 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 练习练习 12: Humans have spent billions of dollars 1.trying (try) to figure out how to get to Mars. Why do we want to go there so 2.badly (bad)? Well, different organizations have different reasons. Dutch organization Mars One wants to put people on Mars by 2027. They say it is just the next step in human curiosity. “Why did Columbus travel west? Why did Marco Polo head east? Because it is that pull, that unknown, or that chance of adventure 3.that makes humans look for new places to explore,” their website says. Wealthy businessman Elon Musk runs a company in the United States. Its name is SpaceX. One of its main goals is to send humans to other planets, including Mars. Musk was born in South Africa but is now 4.a US-Canadian citizen. He agrees that curiosity plays a part in exploring space. But his main reason 5.for wanting to go to Mars is to ensure human 6.survival (survive). He says that for humans to survive in the future, we 14 must learn 7. to live (live) somewhere other than Earth. China has dreams of reaching Mars too. In 2011, along with Russia, they tried to send a probe (探测器) to the planet. Another probe 8.will be sent (send) next year. NASA is also 9.excited (excite) to put humans on Mars. It says going to Mars will help humans learn much more about the universe. “Future exploration could find evidence of life, answering one of the 10.biggest (big) mysteries of the universe: Does life exist beyond Earth?” the NASA website says. NASA says Mars and Earth are very alike. Exploring Mars can help us learn more about our own planets history and future. 提示词提示词答案答案考点考点 1. 2. 3. 4. 5. 6. 7. 15 8. 9.
