On March 23, 2010, Google Inc took a major step in withdrawing(收回) its search-engine services from Beijing to Hong Kong. Google acknowledged that it failed to make progress in talks with the Chinese government for permission to let Google stop censoring(审查) its search results.

Since posting the announcement on its website, Google’s stock(股票) price has fallen from $595 to about $567, while Baidu, the leading search engine in China, has seen its stock price rise by 50%. A potential foreign beneficiary(受益者) is Bing, Microsoft’s new search engine. And while Bing may not exactly have got the keys to a very rich kingdom, its managing group understand their good fortune and have not been shy about sticking the knife into Google. Craig Mundie, a chief officer of Bing, told China Daily that “we feel good enough now,” adding, “but it’s a 20-year journey, and not just three years. And Microsoft is here to stay.”

Several other Chinese Internet companies are no doubt moving swiftly to take advantage of this situation. Both Sohu. com—a Yahoo-like website in China— and a hugely successful instant-messaging company called Tencent(腾讯) are already trying to hire Google China staff. Analysts believe that of the two, Tencent is in the better position. Nearly 70% of China’s 400 million Internet users use instant-messaging, and of those, 80% use Tencent’s system, known as QQ. That’s the major reason why Tencent’s potential market is bigger than Baidu’s, and an insider at the company acknowledges that the search business is full of opportunities.

All the competitors of Google do what the Chinese government requires: censor their search results. If Microsoft and the others intend to be in China “to stay,” as Craig Mundie put it, there is no chance that the censoring principle will change for them.

As to the Google’s exit, one of its investors made the comment recently, “There’re still a lot of us who believe that they’ve made the wise choice. But Google is apparently out and I guess we just get to accept.” However, some Chinese netizens regretted the loss of its professional services on google. cn, such as maps, videos, music and translations.

73.Google.cn stops its business in China because _____.

A. too many companies enter the market         B. its stock price has fallen sharply

C. Chinese companies hire its workers           D. it refuses to censor the search results

74.How many Chinese beneficiaries are mentioned in the passage?

A. Two.               B. Three             C. Four.               D. Five.

75.When Google withdraws, _______.

A. Chinese netizens won’t have any professional service

B. only Chinese companies will provide search service

C. China’s attitude towards censoring won’t be changed

D. the Google managing group will regret its decision

76.A suggested title for this news would be ______.

A. When Google Withdraws From China        B. Who Wins in China’s Search Business

C. Who Will Profit When Google Exits         D. Why Google Loses to Other Competitors

A growing number of workers at Google Inc., Facebook Inc. and other employers are trading in their sit-down desks for standing ones, saying they feel more comfortable and energized. They also are motivated by medical reports saying that sitting for too long leads to increased health risks.

A standing desk sits high off the floor so a worker can either stand at it or sit on a high stool to use it. Officials at Palo Alto-based Facebook say a number of employees asked about standing desks after news articles were published about the health risks of sitting all day.

The stories cited medical studies that tied excessive sitting to increased obesity and other health problems because of factors including a drop in physical activity. A 2010 study by the American Cancer Society found that women who sat more than six hours a day were 37% more likely to die prematurely than women who sat for less than three hours, while the early-death rate for men was 18% higher. The American College of Cardiology released a study in January that found increased mortality (死亡率) among people who sat longer at home than those who didn't.

No one seems to compile statistics on the standing-desk trend. But anecdotal reports suggest Silicon Valley is embracing the movement.

Facebook officials say they have seen an upsurge in requests for standing desks to five to eight a week with a total of between 200 and 250 deployed (配置) at the company of more than 2,000 employees. Facebook also is trying out a treadmill station ─ where a worker can walk or run on a treadmill while tapping at a computer.

Google spokesman Jordan Newman said that 'many employees at Google opt for standing desks, and we offer them as part of our wellness program' though he said he didn't know the exact number.

Greg Hoy, 39 years old, asked for a standing desk shortly after joining Facebook seven months ago as a design recruiter. 'I don't get the 3 o'clock slump anymore,' he said. 'I feel active all day long.'

1.The underlined word “motivated” in paragraph 1 can be replaced by ________.

A．frightened         B．inspired           C．missed            D．discouraged

2.According to paragraph 3, we can know that ________.

A．a drop in physical activity was the only reason why excessive sitting caused increased obesity.

B．women who sat longer were more likely to die prematurely according to a 2010 study by American College of Cardiology

C．according to the study, the early-death rate for men was 18% higher than that for women.

D．the mortality among people who didn’t sat long at home was lower than that among people who did.

3.According to paragraph 5, which of the following statements is true about a treadmill station ________?

A．is a computer that a worker can take along when he walks or runs

B．has been tried out by Facebook and now is very popular with other companies

C．is a place where workers can exercise while working.

D．is a treadmill on which workers can run or walk only after work

4.The passage mainly talks about ________.

A．sitting for too long leads to increased health risks

B．standing desks have replaced sit-down ones in Facebook Inc.

C．more and more workers choose standing desks instead of sit-down ones

D．many employees at Google opt for standing desks

In March, 2016, the pride of humankind was crushed by a computer. Google's AlphaGo defeated the South Korean Go master Lee Sedol four games to one, as the world looked on with shock and awe. Artificial intelligence had suddenly reached a new and unexpected height.

But as smart as AlphaGo is, it's no longer the best Go "player" in the world. Google's artificial intelligence group, DeepMind, has created the next generation of its Go-playing program, called AlphaGo Zero. The new AI program is unique in the way it learned to play Go. Instead of learning from thousands of human matches, as its predecessor (前任) did, AlphaGo Zero mastered Go in just two days without any human knowledge of the game and defeated AlphaGo by day three, reported The Guardian. It then went on to defeat AlphaGo 100 games to zero.

To learn how to play Go, AlphaGo Zero played millions of matches against itself using only the basic rules of the game to rapidly create its own knowledge of it. Like the previous version, it used "reinforcement (增强) learning to become its own teacher," according to DeepMind's website.

"It's more powerful than previous approaches," David Silver, AlphaGo's lead researcher, told The Guardian, "because by not using human data, or human expertise in any fashion, we've removed the constraints of human knowledge and it is able to create knowledge itself."

AlphaGo Zero's approach to self-learning is a significant advancement in AI that could be applied to help solve some of the world's biggest problems, according to a recent research report published in the journal Nature. For example, DeepMind co-founder Demis Hassabis argues that AlphaGo Zero could probably find cures for a number of serious diseases within weeks, according to The Telegraph. Indeed, the AI is now being used to study protein folding, which is connected to diseases such as Parkinson's and Alzheimer's.

So now that AI has gone beyond the bounds of human knowledge, perhaps the question is not about what AI can learn from humans, but what humans can learn from AI. We can only wait and see.

1.What can we learn from the first two paragraphs?

A.AlphaGo defeated Lee Sedol five games to zero.

B.AlphaGo Zero defeated AlphaGo within one day.

C.AlphaGo Zero has become the new best Go player.

D.AlphaGo Zero is the first program to defeat a human at Go.

2.What does the underlined word "constraints" in the fourth paragraph probably mean?

A.advantages B.disadvantages

C.restrictions D.regulations

3.What's the possible application of AI in the future according to the article?

A.Treating diseases. B.Making new Go rules.

C.Solving math problems. D.Creating new proteins.

The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾伦望远镜阵列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.

At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.

What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.

Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.

An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.

1.The main purpose of the Allen Telescope Array is          .

A．to serve for the research of weather predication

B．to prepare for the wars against life from the universe

C．to search for signals from intelligent life in space

D．to observe exploding stars, black holes and other objects

2.From this passage we know that         .

A．the 42 radio telescopes at Hat Creek observatory can work together

B．the total cost of the project came from Paul Allen

C．Hat Creek observatory can receive signals from all parts of the worm

D．Hat Creek observatory is operated by an American named Paul Allen

3.Which of the following is TRUE according to this passage?

A．The Allen Telescope Array takes much more room than former telescopes.

B．The Allen Telescope Array is still being built at present in the United States.

C．Another 42 radio telescopes will be fixed in the Allen Telescope Array.

D．The SETI Institute is against the search for other life forms in the universes.

4.With the help of the Allen Telescope Array,         .

A．astronomers can gather more information than before from other planets

B．humans will have more chances to live on other planets than before

C．humans will be able to find more natural resources on other planets

D．scientists will be able to find more natural resources from other planets

A major earthquake rocked Haiti at 4:53 pm local time on Jan.12, 2010, killing possibly thousands of people but no official figure has been released so far.

The quake, which struck about 15km (10 miles) south-west of the capital, Port-au-Prince, was quickly followed by two strong aftershocks. In the space of a minute, numerous buildings fell down. A five-story U.N. building was also brought down by the 7.3 magnitude quake, the most powerful to hit Haiti in more than 200 years according to the U.S. Geological Survey.

As night fell, the whole city is in total darkness. You can see thousands of people sitting in the streets with nowhere to go. There are people running, crying, screaming. Describing the earthquake as a "catastrophe", Haiti’s president said the cost of the damage could run into billions.

Haiti became the first independent Caribbean state in the early 19th century. Haiti's location, history and attracting climate once made it a tourist hot place. However, decades of poverty, environmental pollution and violence have left it as the poorest nation in the Americas. It has suffered a lot, including four hurricanes and storms in 2008 that killed hundreds.

1.The great earthquake happened to the _______ of the capital city.

2. What can we infer from the underlined sentence?

3. What’s the meaning of the word in bald “catastrophe”?

4.Which statement about Haiti is NOT true?
