8、esponse on the part of the authorities. The General Administration of Quality Supervision, Inspection and Quarantine has made the sensible decision to suspend the imports of Taiwan firms whose products have been con firmed as problematic. That was a necessary move, yet it is sufficient only to preve
9、nt a potential threat to public health from broadening further. At this point, the top priority for the safety authorities should be tracking down and recalling all the suspected beverages, snacks and perhaps raw materials from Taiwan. And it will do so, only if the quantity of problematic products
10、in the mainland market is very, very small, as has been claimed by the companies themselves, and all of them are retractable. However, given the toxic nature of the plasticizer DEHP, its reportedly long existence in Taiwans food industry, as well as the latest report that the harmful substance was d
11、iscovered in imported cosmetics, it might be more meaningful if the inspection extends beyond the designated items and product batches. Since some of the firms involved in the DEHP scandal have mainland subsidiaries, consumers need to know whether the food products they make and sell here are safe o
12、r not. Some of the firms involved have already claimed their mainland companies have independent suppliers, so their products on the mainland are free of DEHP. It would be wonderful if that is the truth. But that statement needs to be confirmed. And this is where our quality watchdogs should step in
13、. Aside from worries about food products made in Taiwan, consumers here are wondering if DEHP, or any similar additive, has been used by local manufacturers. Since no inspection has been targeted specifically at DEHP, nobody can provide a definite answer. But considering the potentially high stakes,
14、 there has to be one. And we do not think it is a good idea for our authorities to wait until DEHPs existence in food products becomes prevalent to launch a probe. Some speculations about the existence of DEHP in mainland food sectors might turn out to be groundless in the end. But because of its ha
15、zardous potential, even as a pre -emptive step, it is essential we act early. 16 More than 500 tainted commodities have been discovered in the mainland. （ A） Right （ B） Wrong （ C） Not mentioned 17 The General Administration of Quality Supervision, Inspection and Quarantine has made decision to suspe
16、nd most of the imports of Taiwan firms. （ A） Right （ B） Wrong （ C） Not mentioned 18 The toxic plasticizer DEHP, was reportedly discovered in imported cosmetics. （ A） Right （ B） Wrong （ C） Not mentioned 19 Our quality watchdogs should step in to confirm if some Taiwan firms products on the mainland a
17、re free of DEHP. （ A） Right （ B） Wrong （ C） Not mentioned 20 Consumers want to know if some of the firms involved in the DEHP scandal are fined. （ A） Right （ B） Wrong （ C） Not mentioned 21 No inspection has been targeted specifically at DEHP or any similar additive. （ A） Right （ B） Wrong （ C） Not me
18、ntioned 22 Speculations about the existence of DEHP in European beverage sectors turned out to be true. （ A） Right （ B） Wrong （ C） Not mentioned 三、 概括大意与完成句子 (第 23-30题，每题 1分，共 8分 ) 下面的短文后有 2项测试任务： (1)第 23-26题要求从所给的 6个选项中为第 2-5段每段选择一个最佳标题； (2)第 27-30题要求从所给的 6个选项中为每个句子确定一个最佳选项。 22 A. increased B. rele

Now, in test flights over the Rocky Mountains, NASA (美国航空航天局 ) engineers have successfully detected clear-air turbulence up to 10 seconds before an
21、 aircraft hits it. Clear-air turbulence often catches pilots by surprise. Invisible to radar, it is difficult to forecast and can hurl (用力抛出去 ) passengers about the cabin. In December 1997, one passenger died and a hundred others were injured when unexpected rough air caused a United Airlines flight
22、 over the Pacific to drop 300 metres in a few seconds. However, passengers can avoid serious injury by fastening their seatbelts. “It is the only antidote (对策 ) for this sort of thing,“ says Rod Bogue, project manager at NASAs Dryden Flight Research Center in Edwards, California. The centres new tur
23、bulence detector is based on lidar, or laser radar. Laser pulses are sent ahead of the plane and these are then reflected back by particles in the air. The technique depends on the Doppler effect. The wavelength of the light shifts according to the speed at which the particles are approaching. In ca
24、lm air, the speed equals the planes airspeed. But as the particles swirl (打漩 ) in rough air, their speed of approach increases or decreases rapidly. The rate of change in speed corresponds to the severity (激烈程度 ) of the turbulence. In a series of tests that began last month, a research jet flew repe
25、atedly into disturbed air over the mountain ridges (山脉 ) near Pueblo, Colorado. The lidar detector spotted turbulence between 3 and 8 kilometres ahead, and its forecasts of strength and duration corresponded closely with the turbulence that the plane encountered. Bogue says that he had “a comfortabl
26、e amount of time“ to fasten his seatbelt. The researchers are planning to improve the lidars range with a more powerful beam. The system could be installed on commercial aircraft in the next few years. 27 What does “clear-air turbulence“ probably mean? (Paragraph 1) （ A） A not very rough storm. （ B）
27、 Unexpected disturbed air. （ C） A kind of visible storm. （ D） A storm over mountain ridges. 28 In December 1997, a United Airlines flight hit unexpected rough air, （ A） causing a let of damage to the plane. （ B） throwing its passengers out of the cabin. （ C） resulting in heavy casualties. （ D） forci
28、ng the pilot to make an emergency landing. 29 The turbulence detector can tell the severity of the turbulence by measuring （ A） the speed of the plane. （ B） the speed, of the light. （ C） the number of particles in the air. （ D） the changes of the particles speed. 30 We can infer from the fifth parag
29、raph that （ A） the lidar detector can successfully forecast turbulence. （ B） researchers are not sure about the effectiveness of the lidar detector, （ C） passenger planes will be used in further experiments. （ D） no more test flights are needed. 31 The last paragraph tells us, among other things, th
30、at （ A） the lidar detector needs improvement. （ B） many airlines are interested in the system. （ C） passengers often forget to fasten their seatbelts. （ D） the lidar detector can be used in a wide range of areas. 32 Electronic Mail During the past few years, scientist the world over have suddenly fo
31、und themselves productively engaged in task they once spent their lives avoiding writing, any kind of writing but particularly letter writing. Encouraged by electronic mails surprisingly high speed, convenience and economy, people who never before touched the stuff are regularly, skillfully, even ch
32、eerfully tapping out a great deal of correspondence. Electronic networks, woven into the fabric of scientific communication these days, are the route to colleagues in distant counties, shared data, bulletin boards and electronic journals. Anyone with a personal computer, a modem.and the software to
33、link computers over telephone lines can sign on. An estimated five million scientists have done so with more joining every day, most of them communicating through a bundle of interconnected domestic and foreign routes known collectively as the internet, or net. E-mail is staring to edge out the fax,
34、 the telephone, overnight mail, and of course, land mail. It shrinks time and distance between scientific collaborators, in part because it is conveniently asynchronous (writers can type while their colleagues across time zones sleep; their message will be waiting). If it is not yet speeding discove
35、ries, it is certainly accelerating communication. Jeremy Bemstei, the physicist and science writer, once called E-mail the physicists umbilical cord. Lately other people, too, have been discovering its connective virtues. Physicists are using it; college students are using it, everybody is using it,
36、 and as a sign that it has come of age, the New Yorker has accelerates its liberating presence with a cartoon an appreciative dog seated at a keyboard, saying happily, “On the Intemet, nobody knows youre a dog.“ 32 The reasons given below about the popularity of E-mail can be found in the passage ex
37、cept _. （ A） direct and reliable （ B） time-saving in delivery （ C） money-saving （ D） available at any time 33 How is the Intemet or net explained in the passage? （ A） Electronic routes used to read home and international journals. （ B） Electronic routes used to fax or correspond overnight. （ C） Elec
38、tronic routes waiting for correspondence while one is sleeping. （ D） Electronic routes connected among millions of users, home and abroad. 34 What does the sentence “If it is not speeding discoveries, it is certainly accelerating com- munication most probably mean? （ A） The quick speed of correspond
39、ence may have ill-effects on discoveries （ B） Although it does not speed up correspondence, it helps make discoveries. （ C） It quickens mutual communication even if it does not accelerate discoveries. （ D） It shrinks time for communication and accelerates discoveries. 35 What does the sentence “On t

41、l, etc. according to the writer? （ A） Their functions cannot be replaced by E-mail. （ B） They will co-exist with E-mail for a long time. （ C） Less and less people will use them. （ D） They will play a supplementary function to E-mail. 37 Ocean Noise Pollution Some scientists say that animals in the o
42、cean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds i
43、nclude the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels (分贝 ) measured in water are different from those measured on land. A noise of one hundred-twenty decibels on land causes pain to human ears. in water, a decibel level of one-hundred ninety-five
44、 would have the same effect. Some scientists have proposed setting a noise limit of one-hundred-twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales (鲸鱼 ). A team of American and Canadian scientists discovered that louder noises-can seriously injure
45、 some animals; The research team found that powerful underwater explosions were causing Whales in the area to lose their hearing. This seriously affected the whales ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed (出血 ) a
46、nd become infected (感染 ). Many researchers whose work depends on ocean sounds object to a limit of one-hundred-twenty decibels. They say such a limit is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean. 37 According to the passage, which of the fol
47、lowing is increasingly dangerous to sea creatures? （ A） The sound of a car. （ B） The sound of voices. （ C） Man-made noise pollution. （ D） The sound of steps. 38 According to the passage, natural sounds include all of the following EXCEPT （ A） sounds made by animals themselves. （ B） ocean drilling. （
48、 C） underwater earthquakes. （ D） the breaking of ice fields. 39 Which of the following is discussed in the third paragraph? （ A） The same noise level produces a different effect on land and in the ocean. （ B） Different places may have different types of noises. （ C） The decibel is not a suitable uni
49、t for measuring underwater noise. （ D） Different ocean animals may have different reactions to noises. 40 Which of the following is true of whales? （ A） They wont be confused by noises. （ B） They are deaf to noises. （ C） Their ability to reproduce will be lowered by high-level noises. （ D） Their hearing will be damaged by high-level noises. 41 According to the passage, what will scientists most probably do in the future? （ A） They will work hard to reduce ocean noise pollution. （ B） They will
