    In 1909 an English newspaper offered ?? 1,000 to the first man to fly across the English Channel in an aeroplane. Today, modern jets cross it in minutes. But at that time it still seemed a good distance. The race to win the money soon became a race between two men. Both were very colourful.

    One was Louis Bleriot. He owned a factory in France that made motor car lamps. He was already well known as a pilot because he had had accidents several times. Some people laughed at him. One man said, “He may not be the first to fly across the Channel but he will certainly be the first to die in an accident!” But Bleriot was really a good and brave pilot. He also had many good ideas about aeroplane design.

    The other man was Hubert Latham. He was half French and half English. He took up flying when his doctors told him he had only a year to live. “Oh, well,” he said, “if I’ m going to die soon, I think I shall have a dangerous and interesting life now.” Latham was the first to try the flight  across the Channel. Ten kilometres from the French coast, his plane had some trouble. It fell down into the water and began to sink under the water. A boat reached Latham just in time. He was sitting calmly on the wing and was coolly lighting a cigarette. Bleriot took off six days later. He flew into some very bad weather and very low cloud. He somehow got to the English side and landed in a farmer’s field. When he did so, a customs (海关) officer rushed up to his plane. Planes have changed since then, but customs officers have not. “Have you anything to declare(报关)?” The officer demanded.

Bleriot was well known as a pilot because ____ .

   A. he was unusually brave

   B. he was quite rich

   C. he had many good ideas about aeroplane design

   D. he had had a few accidents

Why did Hubert Latham want to fly across the Channel?

   A. He thought he could manage it easily.

   B. He wanted to be the first one to cross the Channel.

   C. He knew he only had a year to live.

   D. He had always been interested in flying.

Which of the following is NOT true?

   A. Latham became a pilot on the doctor’s advice.

   B. He was told he could live another year.

   C. His plane had some trouble.

   D. He was saved by a boat when his plane was sinking.

Passage Eleven (Superconducting Materials)

The stone age, The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Welcome to the age of superstuff. Material science -- once the least sexy technology – is bursting with new, practical discoveries led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the picture: from house and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science.

The key to the new materials is researchers’ increasing ability to manipulate substances at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the microscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and never rust or corrode.

A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites – plastic reinforced with fibers of graphite or other compounds – made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantryman’s life by deflecting two bullets in the Grenada invasion.

Some advanced materials are old standard with a new twist. The newest fiberoptic cable that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane.

But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.

1.How many new materials are mentioned in this passage?

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

2.Why does the author mention genetic engineering and computer science?

A.To compare them with the new materials.

B.To show the significance of the new materials on the future world.

C.To compare the new materials to them.

D.To explain his view point.

3.Why is transition difficult?

A.Because transition requires money and time.

B.Because many manufacturers are unwilling to change their equipment.

C.Because research on new materials is very difficult.

[D]Because it takes 10 years.

4.Where lies success of a country in the New Age of superstuff?

A.It lies in research.

B.It lies in investment.

C.It lies in innovation.

D.It lies in application.
