The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.

   Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.

   A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.

   When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.

On the whole, this text is about _________.

  A. special mixtures of gases in deep sea.

  B. the problems a diver faces in deep sea.

  C. air pressure under the surface of sea water.

  D. a kind of illness that man suffers in the sea.

The text does not say so, but it makes you think that ____________.

   A. deep-sea divers should be in good health.

   B. divers explore the deep sea only for treasure.

   C. there is a special mixture of gases under the sea.

   D. diving under the water too quickly causes a kind of illness.

Why does a diver get the bends?

    A. The air in his blood is used up.      B. His diving suit weighs too much.

    C. He comes to the surface too quickly.  D. He tries to do exercise under the sea.

Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can’t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone in bed, taking no notice of the worms. But is it interfering(干涉) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.

Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance(机械维修，保养) as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results will be. And at what point should you stop to treat the old body? Is it morally right to try to push off death by seeking the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You can’t ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there’s life, there’s hope.

When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.

Tokyo - Drivers in China are no longer in a hurry to own Toyota Motor Corp's cars.

Neil Hu, a sales manager at a Toyota dealership in Beijing, said he has stopped charging a 5,000 yuan ($732) premium to customers who want to skip the waiting list for RAV4 sport- utility vehicles. He took the initiative after the Japanese carmaker recalled 75,552 of the SUVs in China last month to fix gas pedals that may stick.

"I heard the situation in the US is pretty bad for Toyota," Hu said. "The recall has impacted us as well."

Toyota, which grew more slowly than competitors in China in 2009, will likely lose more market share and see a decline in local profit margin this year, analysts say. The carmaker has relied on a reputation for quality and safety to sell high margin, mid- to large-size models even as the world's biggest auto market shifts to cheaper, smaller cars, encouraged by government incentives.

With Toyota's brand damaged by global recalls of millions of vehicles, profit margins for its SUVs and Camry and Crown sedans may shrink, said Ashvin Chotai, London-based managing director of Intelligence Automotive Asia Ltd, an industry consultant.

"With this recall saga, Toyota's premium pricing power in China is gone," Chotai said. "Toyota's cars don't have enough good value for money."

Toyota has lost $24.5 billion in market capitalization this year as it recalled over 8 million cars globally to fix defects linked to unintended acceleration. The company faces at least 118 class actions in the US and at least 36 individual lawsuits claiming deaths and injuries caused by sudden acceleration of Toyota or Lexus vehicles.

Toyota President Akio Toyoda flew directly to Beijing on March 2 to apologize for the vehicle defects, after attending US Congressional hearings about the recalls in Washington. He skipped Europe's Geneva auto show, underscoring the growing importance of the Chinese market.

Toyota rose for a fifth straight day in Tokyo, advancing 0.9 percent to 3,580 yen as of 9:44 am local time. The carmaker's shares have fallen 7.7 percent this year.

The company's February China sales rose 30 percent to 45,400 vehicles, underperforming the overall passenger-car.

According to the passage, why did Toyota carmaker recall their cars in China last month? _____________

A. Because it faced law suits in the US

B. Because there were problems with the cars.

C. Because of the importance of the Chinese market

D. Because the customers are not satisfied with the charging of a 5,000 Yuan premium.

What does the underlined phrase“take the initiative” mean?

A. took the advice B. changed his mind C. took the action D. made the decision

Why did Toyota president Akio Toyota skip Europe’s Geneva auto show?

A. Because he did not think it important

B. Because he was not satisfied with the hearing in the US

C. Because he attached importance to the Chinese Market

D. Because he needed to make an apology to Chinese

After the global recalls of millions vehicles, Toyota will be impacted in the following aspects, EXCEPT_________.

A. Its brand will be damaged

B. Its profit margins will shrink

C. It will have to face law suits

D. The president will be fired

Where can read the passage? __________

Broken rubber bands and flat tires requiring replacement could soon be a thing of the past．

French researchers have developed a new kind of rubber that can repair itself when broken．The new rubber is made from widely available materials including vegetable oil and a common industrial chemical．All the materials are considered safe to the environment and can be easily reused．

The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch．When cut, the rubber can be made new again, simply by pressing the two broken ends back together．

The product can be repaired at room temperature, around twenty degrees Centigrade；other self-healing materials require higher temperatures for repair．

Traditionally, rubber substances are made from huge molecules（分子）connected by strong chemical links, or bonds．The new rubber is made of smaller molecules．The molecules are linked together using hydrogen bonds．When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks（超分子网）．When the rubber is cut, the molecules attempt to connect with whatever molecule is near them．When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new．

However, time is an important element in the process．If the broken ends are not brought together quickly, a repair is not possible．This is because molecules will form bonds with molecules on their own side．The inventors say the surfaces of the rubber can be repaired within a week of being separated．

The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris．The organization is part of France's National Center for Scientific Research．The new material is described in greater detail in the research publication Nature．

According to the introduction, which of the following is NOT the advantage of the new rubber?

A．It can be made as easily as common rubber．

B．It is environmentally-friendly．

C．It can repair itself at room temperature．

D．It is made of smaller molecules．

What does the 5th paragraph mainly tell us?

A．Why the new rubber is unique．

B．Why the new rubber can repair itself．

C．The new rubber is made from huge molecules．

D．The new rubber is different from the common rubber．

If we want to know more about the technology of this kind of new rubber, where can we get the information?

A．In the researchers' diary．    B．In a guide book．

C．In a research magazine．       D．In a newspaper．
