1 . Cloning has always been with us and is here to stay. It is a way of making     1     exact copy of another animal or plant. Cloning plants is straightforward while cloning animals is very complicated. The process of cloning is a difficult task     2    (undertake) Many attempts to clone mammals failed. But finally the determination and patience of the scientists paid     3     in 1996 with a breakthrough-the cloning of Dolly the sheep.

At first the fact     4     she seemed to develop normally was very encouraging. Then came the     5    (disturb) news that Dolly had become seriously ill, which made cloning scientists cast down. Meanwhile, Dolly’s appearance raised a storm of     6    (object) and had a great impact on the media and public imagination.     7    (apparent) it became controversial. Although at present human egg cells and embryos     8    (need)for cloning research are hard to obtain, newspapers wrote of evil leaders     9    (hope) to clone themselves to attain their ambitions. Religious leaders also raised moral questions. Some countries reformed their legal systems and     10    (forbid) research into human cloning, but others like China and the UK, continued to accumulate evidence of the abundant medical aid that cloning could provide.

A robot used for housework was going to be tested out in a family. He looked like a tall and handsome man with smooth black hair, speak in a deep voice. Larry was going to be away from home, so he hired such a robot to accompany with his wife Claire. Claire didn’t like the idea at the beginning, and she agreed to it at last. At her first sight of Tony, Claire was alarming. When Tony offered to help her dress, Claire felt embarrassed. Gradual Tony began to win Claire’s trust. He helped Claire realize her dreams by making her home elegant, giving her a new haircut, changing the makeup she wears and giving her advice on her dresses. Therefore at the party all the guest who were invited were filled with admiration when they saw her house was completely transformed. At same time, Tony left a deep impression on all of them. After the test, the company was satisfied with Tony’s report because she had successfully made a woman regain her confident, although he shouldn’t have her fall in love with him.

4 . From self-driving cars to carebots (care+robots) for elderly people, rapid development in technology has long represented a possible threat (威胁) to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence (AI) continues to change businesses.

“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia-Pacific. A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.

The report is based on interviews with 200 experts, business leaders and young people from Asia-Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates. But the report states, “Losing occupations does not necessarily mean losing jobs—just changing what people do.” Growth in new jobs could occur as much, according to the research. “The growth of companies that have the speed and technological know-how will directly challenge big companies,” it states.

A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith, the report’s co-author.

“Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft’s Jonathan Grudin told researchers.

1. What is the first paragraph mainly about?

A．The result of job reduction.

B．The fast development of AI.

C．The future life of elderly people.

D．The influence of technology on jobs.

2. What will people most probably do in the future?

A．Take the place of AI.

B．Work in a traditional way.

C．Take up jobs requiring creativity.

D．Enjoy life without working anymore.

3. What can be known from Grudin’s words in the last paragraph?

A．Job unemployment will stay high.

B．More jobs tend to appear in the future.

C．Job competition is likely to grow fiercer.

D．Technology will have less control over jobs.

4. What is the best title for the text?

A．Are People Losing Their Jobs?

B．The Requirements for Future Jobs

C．The Challenging Life in the Future

D．Does Technology Simplify Everything?

5 . 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。选项中有两项为多余选项。

For generations, people have dreamed of traveling to Mars to explore Earth’s closest planetary neighbor. The American Space Agency, NASA, and other space agencies have announced plans to send people to the Red Planet.    1    .

In the United States, some volunteers are learning how people will react to months of separation from other humans on a Mars base.    2     But actually, they are living in Hawaii. The project is called HI-SEAS. NASA has provided financial support for the work.

Six people are living on a make-believe Mars Base. They are isolated high on top of Mauna Loa, a volcanic mountain on the Big Island of Hawaii, whose environment is as close to Mars as we can find on Earth.     3     When measured from its base, deep in the ocean, Mauna Loa is the second largest mountain in our solar system. Because it is so high, the land is not warm or rich with plants, like the rest of Hawaii. Visually, it is very similar to what you see on Mars. They can walk across red lava rock from the volcano and see the wonderful volcanic material. There is really no visible plant life or animal life.

The six member HI-SEAS crew is mostly self-sufficient. They take care of themselves.    4    

But the individuals bringing those supplies cannot communicate with volunteers inside the base. The current crew has been living in the base since October, and will stay until June. Crew members communicate with the outside world through e-mail and blogs. They also produce videos on the YouTube website.    5    

Food and supplies are brought to them.

A．But such a manned mission is years away.

B．Mars has the largest volcanic mountain in the solar system.

C．They are spending eight months in an area that looks much like the surface of Mars.

D．Mauna Loa is 2,500 meters above sea level.

E．Conditions on the surface of Mars are closer to the conditions on Earth.

F．For now, on a mountaintop in Hawaii, volunteers are getting a taste of life on a future Mars base.

G．Food and supplies are brought to them.

6 . Recently a Russian friend came to visit me. It was one of her lifelong dreams to visit London.

7 .    Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict.” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and a sports shirt—to the office. He hardly ever wears a necktie. “I am working harder than ever.” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code.” “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative(保守的)dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale(心境，士气). Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”
