13、t parks, where he would wait patiently while they enjoyed the rides. As far as he was concerned, there was not (21) that was truly enjoyable about such places; the grounds were dirty, the material shabby, the parents bored. And so it is that, around 1934 or 35, the idea began to (22) in his mind (23

14、) perhaps something could be done to bring more pleasure to children and adults (24) . It was a modest idea at first. When Disney brought it (25) in the open in 1948 ,he was merely proposing a small amusement area (26) a corner of the Burbank loteleven acres all (27) . Even so, the plan was not mode

(30) he went, either in the United States or (31) , he visited parks, county fairs, circuses, carnivals, open air attractions of all kindsand, (32) all, zoos.

17、4) more if it was to visit another zoo. Most of the places that he saw looked dirty and sad (35) Disney.

18、about his (37) , the more enthusiastic Disney felt about it. Although he was not (38) to the business side of such a venture, the park (39) more than a moneymaking device for him.

Erosion is one problem. The steps and stones of major pop

24、ular sites like Shakespeares birthplace or Stonehenge are literally being worn away by millions of foreign feet. The remedy in the case of Britain s best known prehistoric monument has been to use railings to keep visitors at a distance. Such measures can hardly be adopted in the house of the Bard,

25、however, where tourists want to enter the actual building.Overcrowding in cities, towns and villages is another problem. Traffic jams are an outcome. In narrow roads, tourist vehicles cause congestion. Local traders and residents cannot get around to do their work. Car parks fill up, so strangers pa

26、rk their cars where they can: in streets, across gate ways, in lay-bys, or even in private driveways. This causes obstruction. The sheer weights of incomers can be a hazard. Thus Venice, a city built for half a million inhabitants, is swollen by another half million who populate the city daily in th

27、e tourist season eight million visits each year. The mayor recently decided to limit visitors to 90,000 a day: the only way to save the city from inundation.Pollution is a further consequence. The Lakes are popular for people who enjoy water-sports, such as water-skiing, power boat racing and swimmi

28、ng, but boats pump sewage directly into the water. Facilities can be provided to prevent this happening, but this is costly. There are also problems with litter.The threat to wildlife habitats is yet another result. Tourists around the Lakes destroy vegetation. This is harmful to animals which build

29、 their nests along the shores, Wildlife refuges have been created which have helped protect these natural sites. On the Greek island of Zakinthos, the breeding beaches of the rare loggerhead turtle are being threatened by tourist disturbance. Local conservationists try to monitor and protect the tur

30、tles but they have been attacked by the angry owners of taverns and hotels who make lucrative profits from bars or renting sunbeds and umbrellas. Government compensation payments for the loss of business might be the answer, but this would be costly.（分数：5.00）(1).Which of the following statements bes

31、t summarizes the main idea of the passage?A. The development of tourism has brought about environmental problems.B. Tourism should not develop at the cost of the environmental destruction.C. Measures taken to protect the environment prove to be ineffective.D. Tourism is developing for the sole purpo

32、se of making money.（分数：1.00）A.B.C.D.(2).As a result of over-development of tourism, Venice _.A. is overcrowded with cars B. is overloadedC. is worn away D. is badly polluted（分数：1.00）A.B.C.D.(3).Paragraph 3 points out that the Lakes _.A. have too many boats on them B. are overcrowded on the beachesC.

34、s and villages is another problem caused by over-development of tourism, an outcome of which is _.A. that strangers park their cars where they canB. that local traders and residents cannot get around to do their workC. that the sheer weights of incomers can be a hazardD. traffic jams（分数：1.00）A.B.C.D

35、.九、Passage 2(总题数：1，分数：5.00)It is hard to track the blue whale, the oceans largest creature which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into i

36、ts behavior.So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navys formerly top-secret system of underwater listening devices spanning the oceans. Tracking w

37、hales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies,Earth scientists announced at a new

38、s conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The spe

39、ed of sound in water is roughly one mile a second, slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope does when it carries faint noises from a patients chest to a doc

40、tors ear. This focusing is the main reason that even relatively weak sounds in the ocean especially low-frequency ones can often travel thousands of miles.（分数：5.00）(1).The passage is chiefly about _.A. an effort to protect an endangered marine speciesB. the civilian use of a military detection syste

41、mC. the exposure of a Navy top-secret weaponD. a new way to look into the behavior of blue whales（分数：1.00）A.B.C.D.(2).The underwater listening system was originally designed _.A. to trace and locate enemy vesselsB. to monitor deep-sea volcanic eruptionsC. to study the movement of ocean currentsD. to

42、 replace the global radio communications network（分数：1.00）A.B.C.D.(3).The deep-sea listening system makes use of_.A. the sophisticated technology of focusing sounds under waterB. the capability of sound to travel at high speedC. the unique property of layers of ocean water in transmitting soundD. low

43、-frequency sounds traveling across different layers of water（分数：1.00）A.B.C.D.(4).It can be inferred from the passage that_.A. new radio devices should be developed for tracking the endangered blue whalesB. blue whales are no longer endangered with the use of the new listening systemC. opinions diffe

44、r as to whether civilian scientists should be allowed to use military technologyD. military technology. has great potential in civilian use（分数：1.00）A.B.C.D.(5).Which of the following is true about the Navy underwater listening network?A. It is now partly accessible to civilian scientists.B. It has b

45、een replaced by a more advanced system.C. It became useless to the military after the cold war.D. It is indispensable in protecting endangered species.（分数：1.00）A.B.C.D.十、Passage 3(总题数：1，分数：5.00)In the atmosphere, carbon dioxide acts rather like a one-way mirror - the glass in the roof of a greenhous

46、e which allows the suns rays to enter but prevents the heat from escaping.According to a weather experts prediction, the atmosphere will be 3C warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would

47、begin to melt, thus raising sea level several metres and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere, possibly resulting in an alteration of the earths chief food-growing zones.In the past, conc

48、ern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming: in other words, by a warmin

49、g on the scale that will possibly take place in the next fifty years from the burning of fuels.Satellite pictures show that large areas of Antarctic ice are .already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth.However, most of the fuel is burnt in th
