Answer the questions below each text by choosing A, B, C or D. (40 points)31 Ever since they were first st

15、aged in 19th century Europe, worlds fairs have enabled people from around the globe to visit wondrous pavilions where they can discover distant lands and new technologies. The 2006 worlds fair is no exception, but it also has a decidedly new- era twist: the whole event happens in cyberspace.A nonpro

16、fit project dreamed up by Americans Carl Malamud, a computer consultant, and Vinton Cerf, and Internet pioneer and telecommunications-company vice president, the Internet 2006 World Exposition is a digital work in progress, a multi-chambered forum that cybernauts can help build and renovate througho

17、ut the yearand perhaps long after the fairs official close in December.While high-tech pavilions set up by sponsoring corporations are featured prominently, as in real fairs, this virtual exposition is closer in spirit and reality to a vast bustling bazaar, a marketplace for the talents and offering

18、s of thousands of individuals and small groups. Anyone with a computer and a modem can not only “attend“ but also participate as an exhibitor by creating an individual multimedia Website.Getting the fair up and running was by no means easy. Malamud, 36, spent the past year shuttling among 30 countri

19、es, lobbying companies that initially dismissed the project as unwieldy and unworkable. While some nations immediately supported the idea, others completely missed the point of Malamuds vision: to make the fair a public-works project that focuses on what the Internet can offer expert or novice. Once

20、 grass-roots groups started backing the project, though, businesses were not far behind. By donating equipment and services, these companies will gain access to millions of potential consumers eager to see the firms latest technologies.Since the expositions Jan. 1 launch, as many as 40,000 visitors

21、each day from more than 40 countries have tried the major Websites. Most virtual visitors log on from the U.S and Japan, but the United Arab Emirates, Sweden, Singapore and Estonia have been represented. Comments logged in the fairs guest book are overwhelmingly positive. “Wow, the world is shrinkin

22、g“, wrote a visitor from the Netherlands. Since their initial hesitancy, the major sponsors-primarily telecommunications and software companieshave become firm believers. Beyond the diversity of content and international scope, the fair is a technological marvel.The fastest international link ever i

23、nstalled, this pipeline could be the first step toward laying a permanent network that will eventually hardwire every nation in the world into the Internet. The organizers hope that the infrastructureand awareness-nurtured by this exposition will launch a boom in Net use.31 The organizers thinks tha

24、t the effect on Net use of the good worlds fair is _.（A）hardly positive.（B） dubiously-oriented.（C） quite instantaneous.（D）far-reaching.32 We can learn from the text that _.（A）public visitors intended to reap great profits in the fair.（B） some countries initially hesitated to support the project.（C）

25、technological progress usually precedes an economic boom.（D）sponsoring corporations once dismissed the technology.33 The technological fair is intended by its organizers to be _.（A）in the interests of public.（B） for the sake of exhibitors.（C） at the mercy of firms.（D）to the prejudice of users.34 The

26、 expression “a vast bustling bazaar“ (Para. 3) best connotes _.（A）eager.（B） diverse.（C） active.（D）spacious.35 In the writer opinion, the virtual exposition in the new era is _.（A）profitable.（B） rewarding.（C） fruitless.（D）successful.36 When enthusiasts talk of sustainable development, the eyes of mos

27、t people glaze over. There is a whiff of sack-cloth and ashes about their arguments, which usually depend on people giving up the comforts of a modern economy to achieve some debatable greater good. Yet there is a serious point at issue. Modern industry pollutes, and it also seems to cause significa

28、nt changes to the climate. What is needed is an industry that delivers the benefits without the costs. And the glimmerings of just such an industry can now be discerned.That industry is based on biotechnology. At the moment, biotechs main uses are in medicine and agriculture. But its biggest long-te

29、rm impact may be industrial. Here, it will diminish demand for oil by taking the cheapest raw materials imaginable, carbon dioxide and water, and using them to make fuel and plastics.Plastics and fuels made in this way would have several advantages. They could accurately be called “renewables“, sinc

30、e nothing is depleted to make them. They would be part of the natural carbon cycle, borrowing that element from the atmosphere for a few months, and returning it when they were burned or dumped. That means they could not possibly contribute to global warming. And they would be environmentally friend

31、ly in other ways. Bioplastics are biodegradable, since bacteria understand their chemistry and can therefore digest them. Biofuels, while not quite “zero emission“ from the exhaust pipe (though a lot cleaner than petrol and diesel), would be cleaner overall even than the fuel-cell technology now bei

32、ng touted as an alternative to the internal-combustion engine. That is because making the hydrogen that fuel cells use is not an environmentally friendly process, and never will beunless it, too, uses biotechnology.All this will, in the end, depend on costs. But these do not look unfavourable. Alrea

33、dy, the price of bioplastics overlaps the top end of the petroleum-based plastics market. Bulk production should bring prices down, particularly when the raw materials are free. Meanwhile, ethanol would be a lot easier to introduce than fuel cells. Existing engines will run on it with minor tweaking

34、, so there is no need to change the way ears are made. And since, unlike hydrogen, it is a liquid, the fuel-distribution infrastructure would not need radical change.The future could be green in ways that traditional environmentalists had not expected. Whether they will embrace that possibility, or

35、stick to sack-cloth, remains to be seen.36 According to the author, applying biotechnology to industry（A）has brought about sustainable development.（B） proves to be nothing but an imagination.（C） will deprive most people of modern comforts.（D）contributes to the environmentally sound development.37 Th

36、e word “depleted“(Paragraph 3) can be substituted by（A）exhausted.（B） discarded.（C） abandoned.（D）wasted.38 One advantage of the biofuels is that（A）they will not pollute the environment.（B） they are degradable by bacteria.（C） they are cheaper than hydrogen fuels.（D）they are suitable for internal-combu

37、stion engine.39 According to paragraph 4, _.（A）the prospect of biotechnology industry depends on its marketing cost.（B） fuel cells are easier to be utilized in auto industry than biofuels.（C） biofuels will replace the fuel cells in the near future.（D）the price of bioplastics shows a downward trend.4

38、0 The best title for the passage might be（A）A World Clean Yet in Comfort.（B） Conserving Before Its Too Late.（C） There Is Only One Earth.（D）The Fuel-Hungry Planet.41 When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the a

39、ffliction and find ways to combat it. Oftentimes, success is achieved, as medical science is able to isolate the parasite, germ or cell that causes the problem and finds ways to effectively kill or contain it. In the most serious of cases, in which the entire population of a region or country may be

40、 at grave risk, it is deemed necessary to protect the entire population through vaccination, so as to safeguard lives and ensure that the disease will not spread.The process of vaccination allows the patients body to develop immunity to the virus or disease so that, if it is encountered, one can war

41、d it off naturally. To accomplish this, a small weak or dead strain of the disease is actually injected into the patient in a controlled environment, so that his bodys immune system can learn to fight the invader properly. Information on how to penetrate the diseases defenses is transmitted to all e

42、lements of the patients immune system in a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped and trained to deal with it, having already done so be

43、fore.There are dangers inherent in the process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much for the body to handle, resulting in the immune system succumbing, and, therefore, the patients death. Such is the case of the smallpox vaccine, des

44、igned to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers. Approximately 1 in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it. Thus, if the entire populatio

45、n of the United States were to receive the Smallpox Vaccine today, 3000 Americans would be left dead.Fortunately, the smallpox virus was considered eradicated in the early 1970s, ending the mandatory vaccination of all babies in America. In the event of a reintroduction of the disease, however, mand

46、atory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.41 The best title for the text may be（A）Vaccinations: A Blessing or A Curse.（B） Principles of Vaccinations.（C） Vaccines: Methods and I

47、mplications. （D）A Miracle Cure Under Attack.42 What does the example of the Smallpox Vaccine illustrate?（A）A possible negative outcome of administering vaccines.（B） The practical use of a vaccine to control an epidemic disease.（C） A method by which vaccines are employed against the disease.（D）The ef

48、fectiveness of vaccines in curing certain disease.43 The phrase “ward it off naturally“ (Paragraph 2) most probably means（A）dispose of it naturally.（B） combat against it readily.（C） attend to it reluctantly.（D）split it up properly.44 Which of the following is true according to the text?（A）Saving the

49、 majority would necessarily justify the death of the minority.（B） The immune system can be trained to fight weaker versions of a disease.（C） Mandatory vaccinations are indispensable to the survival of the populace.（D）The process of vaccination remains a mystery to be further resolved.45 The purpose of the author in writing this passage is（A）to comment and criticize.（B） to demonstrate and argue.（C） to inter
