7、hings with credit cards. There are now 565 million credit cards worldwide, but it doesnt stop there. Debit cards (电子记账卡) are being issued by banks, and store cards are being offered by many department stores. Bills and coins are gradually being replaced by “plastic money.“ In many countries, phone c
8、ards have been introduced for people to use in pay phones. In addition, cards made of paper are being replaced by plastic ones by many organizations and clubs. For example, if you belong to a sports club, your membership card may well be made of plastic.How safe is the plastic used to make these car
9、ds, though? Until now, most cards have been made from a plastic called PVC. While PVC is being produced, harmful chemicals are released into the atmosphere. One of the most dangerous chemicals that is released is dioxin, which is known to cause cancer in humans. A further problem is that, when a PVC
10、 card is thrown away, it is not biodegradable; this means that it does not “break down“ and cannot be recycled. Obviously, recycling reduces pollution of the environment.The executive director of the environmental organization and charity Greenpeace, Peter Melchett, says, “If there is a solution to
11、this-and an alternative then it would be madness not to use it.“ Greenpeace has found a solution and an alternative. Their new credit card is made entirely from a biodegradable plastic that uses plants. The card breaks down in around three months in soil; in this way, it is recycled. In contrast, a
12、PVC card lasts for centuries. Greenpeace hopes that many organizations will soon follow their example and issue cards that do not threaten the public health.（分数：7.00）(1).Fewer and fewer credit cards are made of paper.A. Right B.

The lessons will be carried into c
19、lassrooms all over a city, or even an entire country.After a televised lesson has been given, the classroom teacher will take over for the all-important “follow-up“ period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion.The teacher in the
20、classroom will have additional electronic tools. On the teachers desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifica

29、第二篇(总题数：1，分数：15.00)Flying the Hypert SkiesA little airplane has given new meaning to the term “going hyper. “The Hyper-X recently broke the record for air-breathing jet planes when it traveled at a hypersonic speed of seven times the speed of sound. Thats about 5,000 miles per hour. At this speed, y
30、oud get around the world - flying along the equator (赤道) - in less than 5 hours.The Hyper-X is an unmanned,experimental aircraft just 12 feet long. It achieves hypersonic (超音速的) speed using a special sort of engine known as a scramjet. It may sound like something from a comic book,but engineers have
31、 been experimenting with scramjets since the 1960s.For an engine to burn fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. A scramjet (紧急刹车) engine goes
32、 as fast as a rocket, but it doesnt have to carry its own oxygen supply. A scramjets special design allows it to obtain oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion (燃烧) flames. However, a scramjet engine works properly
33、only at speeds greater than five times the speed of sound. A booster rocket carried the Hyper-X to an altitude of about 100,000 feet for its test flight. The aircrafts record-beating flight lasted just 11 seconds. Although the little planes self-powered flight lasted only 11 seconds, that brief jour
34、ney on March 27 makes a major milestone on the way to a new breed of very fast airplanes, comments Werner J. A. Dahm of the University of Michigan in Ann Arbor. In the future, engineers predict, airplanes equipped with scramjet engines could transport cargo quickly and cheaply to the brink of space.
35、 Such hypersonic jets could potentially carry passengers anywhere in the world in just a few hours.Out of the three experimental Hyper-X aircrafts built for NASA, only one is now left. The agency has plans for another 11-second hypersonic flight, this time at 10 times the speed of the sound.（分数：15.0
36、0）(1).The Hyper-X broke the record becauseA. it was the first air-breathing jet plane.B. it flew along the equator.C. it flew at speeds smaller than five times the speed of sound.D. it traveled at a supersonic speed.（分数：3.00）A.B.C.D.(2).What kind of an engine did the Hyper-X use?A. A jet engine that
37、 gets oxygen from the air.B. A scramjet engine that doesnt carry its own oxygen supply.C. A rocket engine that carries its own supply of oxygen.D. A jet engine that uses no oxygen.（分数：3.00）A.B.C.D.(3).What is NOT true about the scramjet engine?A. It goes slower than a rocket.B. It extracts oxygen fr
38、om the air that flows through the engine.C. It works only at speeds greater than five times the speed of sound.D. It doesnt carry its own oxygen supply.（分数：3.00）A.B.C.D.(4).What did Werner J. A. Dahm of the University of Michigan say about the Hyper-X test flight?A. It indicated the birth of a very
39、fast airplane.B. It was self-powered, so it lasted only 11 seconds.C. It can transportcargo quickly and cheaply to the brink of space.D. It is a major milestone in the journey of making a new type of very fast airplanes.（分数：3.00）A.B.C.D.(5).What has NASA planned to do?A. To make another 11-second hy
40、personic flight at 10 times the speed of the sound.B. To make three more Hyper-X experiments.C. To retest the aircraft that is left.D. To make the aircraft fly higher and longer.（分数：3.00）A.B.C.D.七、第三篇(总题数：1，分数：7.00)Dreams of FlightThe story of mans dream of flight, of his desire to reach the stars,
41、is as old as mankind itself. According to Greek legend, Daedalus was the first man to fly. He and his son had been kept on an island, in order to escape, Daedalus shaped wings of wax (蜡) into which he stuck bird feathers. During their flight, his son flew too high and the sun melted the wax. He was
42、drowned in the sea. The father was supposed to have continued his Night and reached Sicily, several hundred miles away.There is also an English legend of King Bladud who, during his rule in the ninth century B.C., used wings to fly. But his flight was short-lived and he fell to his death. The dream
43、of flying continued, but in all the legends, the flier rose like a bird only to fall like a stone. It took hundreds of years that men flew up into the air and returned to earth safely.The first man to approach flying on a scientific basis was an Englishman who lived during the thirteenth century. He
44、 looked at the air about us as a sea, and he believed that a balloon could float on the air just as a boat did on water. Almost four hundred years later, an Italian priest applied his principle of air flight. He designed a boat, which would be held in the air by four hollow spheres (空心球). Each of th
45、e four balls was to be 20 feet in diameter (直径) and made of very thin copper. But his boat was never .built since it was not possible to make spheres of such thin metal and such size in those days.After studying the flight of birds and the movement of the air, a great scientist of the fifteenth cent
46、ury concluded that birds flew because they flapped (摆动) their wings and that it was possible for man to do the same. So a kind of flapping-wing flying machine was invented. Many men tried and failed to fly with flying machines. It was not until 1890 that people discovered why this method would never
47、 succeed-man could not develop sufficient power with his arms and legs.（分数：7.00）(1).How did Daedalus manage to escape to Sicily, according to the passage?A. He killed the guards and got out of the island.B. A god came to rescue him and took him away.C. His son came to rescue him and took him away.D.
48、 He made wings of wax and flew away from the island.（分数：1.40）A.B.C.D.(2).According to the English legend, King Bladud lost his life becauseA. he flew too far.B. he flew too high.C. he fell to the ground.D. he was hit by a stone.（分数：1.40）A.B.C.D.(3).The first scientific air flight was designed byA. a
49、 Greek.B. an Englishman.C. a Chinese.D. an Italian.（分数：1.40）A.B.C.D.(4).The priest failed to build the boat becauseA. he could not raise enough money.B. his design was not scientific.C. he could not find enough copper.D. copper spheres could not be made as designed.（分数：1.40）A.B.C.D.(5).According to the last paragraph, man could not fly with flapping-wing flying machines becauseA. he could not develop adequate power
