25、 are being offered by many department stores. Bills and coins are gradually being replaced by plastic money. In many countries, phone cards 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 e

26、xample, 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 cards, 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 th

27、e most dangerous chemicals that is released is dioxin, which is known to cause cancer in humans. A further problem is that, when a PVC 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 environmen

28、t.The executive director of the environmental organization and charity Greenpeace, Peter Melchett, says, If there is a solution to 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 biodegr

29、adable plastic that uses plants. The card breaks down in around three months in soil; in this way, it is recycled. In contrast, a 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.Fewer and few

31、 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 drowned in the sea. The father was supposed to have continued his Night and reached Sicily, several hundred miles away.

32、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 of flying continued, but in all the legends, the flier rose like a bird only to fall like a stone. It took hundreds of

33、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 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

34、. 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 the 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 wa

35、s 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 century concluded that birds flew because they flapped (摆动) their wings and that it was possible for man to do the same. So

36、 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 succeed-man could not develop sufficient power with his arms and legs.How did Daedalus manage to escape to Sicily, acc

37、ording 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. He made wings of wax and flew away from the island.7.Flying the Hypert Skies 8.Science and TruthFINAGLE is not a word that most pe

38、ople associate with science. One reason is that the image of the scientist is of one who always collects data in an impartial (51) for truth. In any debate - over intelligence, schooling, energy-the (51) science says usually disarms opposition.But scientists have long acknowledged the existence of a

39、 finagle factora tendency by many scientists to give a helpful change to the data to (53) desired results. The latest of the finagle factor in action comes from Stephen Jay Gould, a Harvard biologist, (54) has examined the important 19th century work of Dr. Samuel George Morton. Morton was famous in

40、 his time (55) analysing the brain size of the skulls as a measure of intelligence. He concluded that whites had the (56) brains, that the brains of Indians and Blacks were smaller, and therefore, that whites constitute a superior race.Gould went back to Morton’s original data and concluded th

41、at the (57) were an example of the finagle at work. He found that Morton’s discovery was made by leaving out embarrassing data, using incorrect procedures, making simple arithmetical (58) (always in his favour) and changing his criteria-again, always in favour of his argument. Morton has been

42、thoroughly discredited by now and scientists do not believe that brain size reflects (59) .But Gould went on to say Morton’s story is only an example of a common problem in (60) work. Some of the leading figures in science are believed to have (61) the finagle factor. Gould says that Isaac New

43、ton fudged out to support at least three central statements that he could not prove. And so (62) Claudius Ptolemy, the Greek astronomer, whose master work, Almagest, summed up the case for a solar system that had the earth as its centre. Recent studies indicate that Ptolemy (63) faked some key data

44、or resorted heavily to the finagle factor.All this is (64) because the finagle factor is still at work. For example, in the artificial sweetener controversy, for example, it is said that all the studies sponsored by the sugar industry find that the artificial sweetener is unsafe, while all the studi

45、es sponsored by the diet food industry find nothing (65) with it.51（）A.searchB.learningC.teachingD.dialogue9.It’s in the CardsIn recent years, more and more people have been paying for things with credit cards. There are now 565 million credit cards worldwide, but it doesn’t stop there.
