1、When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction 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 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 patient\'s body to develop immunity to the virus or disease so that, if it is encountered, one can ward 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 body\'s immune system can learn to fight the invader properly. Information on how to penetrate the disease\'s defenses is transmitted to all elements of the patient\'s 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 before.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 patient\'s death. Such is the case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers. Approximately l in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3,000 Americans would be left dead.Fortunately, the smallpox virus was considered eradicated in the early 1970\'s, ending the mandatory vaccination of all babies in America. In the event of a re-introduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.The purpose of the author in writing this passage is____.【单选题】

2、Cars Are Good for the Environment，HonestBritain\'s motor industry is planning a major publicity campaign to counter what it sees as an official anti-car bias and to improve the environmental image of the cars, according to documents leaked to the pressure group, Friends of the Earth (FOE). The five-year campaign could cost up to ￡12 million.The internal document which was produced last month by the Society of Motor Manufacturers and Traders, says that the "ultimate objective of the campaign must be to protect the long-term commercial freedom of the motor industry and the lifestyle freedom of car users". ____ European car manufacturers have already agreed with the European Com mission to reduce CO2 emissions from new cars by 25 percent to target of 140 grams per kilometer by 2008. However, the document also reveals that the industry is someway from meeting the target. For example, last year\'s new cars exceed an average of 192 grams per kilometre—some 37 percent above the target.To help control these emissions, the government has proposed replacing the flat rate annual tax on cars with a tax related to engine size so that owners of large gas-guzzler would pay more than owners of small cars. But the motor industry opposes taxes on persons owning cars preferring taxes on use.Richard Barnet, the society\'s media manager, says: "We will work with the government to practice a practical system. " But Ian Willmore of FOE says the industry “may pose as partners of the government, but its real intention is to frustrate serious attempts to reduce traffic levels”.【单选题】

A.The campaign will highlight the motor industry\'s efforts to reduce emissions of carbon dioxide.

B.But the motor industry opposes taxes on persons owning cars preferring taxes on use.

C.The five-year campaign could cost up to ￡13 million.

D.The reason why cars are good for the environment is obvious.

E.But Ian Willmore of FOE says the industry “may pose as partners of the government, but its real intention is to frustrate serious attempts to reduce traffic levels”.

F.For example, last year\'s new cars exceed an average of 192 grams per kilometre—some 38 percent above the target.

正确答案:A

答案解析:前文提到了campaign“活动”，由后文可知本段对该活动进行解释，所以选择A。

3、Intellectual DisabilityPeople with intellectual disability form one of the largest single disability groups in a community. Intellectual disability refers to a general slowness to learn and function within society, and the identification of intellectual disability is usually based on an assessment of a person\'s performance in a variety of tests. An individual\'s level of performance, as assessed, can change with time and circumstances. With skilled training and opportunity for development, people with intellectual disability have much greater potential for acquiring skills and for participation in community life than previously had been thought possible.In many western societies, five categories of intellectual disability have traditionally been used in order to indicate the perceived degree of difficulty an individual has with learning. All five may occur in either children, adolescent or adult, and show as mild, moderate, severe, profound or multiple intellectual disability.For the majority of intellectual disabilities, there is no identifiable cause but there are some causes that are well documented. They include: brain damage at birth due to lack of oxygen—prolonged labor during childbirth; brain damage before birth due to factors such as rubella (风疹), drug or diet-related problems; damage after birth due to illnesses such as encephalitis(脑膜炎) or accident; hereditary defects in the genes; abnormal chromosome count resulting in, for example, Down Syndrome(唐氏综合症).Like everyone else, people with an intellectual disability need a rewarding job, a satisfying place to live and a good social life. But they may need extra support to achieve these things. Good support services are based on the principle of normalization—which means enabling people to be part of the community like everyone else,With the introduction of the intellectually disabled into communities, there is a need to promote awareness of communication. Although many people may have little experience in talking with an intellectually disabled person, there are common guidelines that can simplify the interaction. Firstly, it is useful to remember that people with disabilities have feelings. Speaking in the same friendly manner as you would to anyone else is also recommended. Being prepared to wait a little longer for replies during a conversation with an intellectually disabled person would undoubtedly benefit the exchange.Five categories of intellectual disability have traditionally been used to____.【单选题】

A.assess the degree of difficulty an individual has with learning

B.illnesses such as encephalitis or accident

C.they also have feelings

D.an assessment of a person\'s performance in a variety of tests

E.factors such as rubella, drug or diet-related problems

F.benefit the exchange

正确答案:A

答案解析:根据题干线索词Five categories定位原文至第二段第一句“five categories of intellectual disability have traditionally been used in order to indicate the perceived degree of difficulty an individual has with learning”，由此推断，句中画线部分即为所需添加成分。A选项属于原文复现，故为正确答案。

5、Smart Window Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He\'s a professor of solid-state physics at Uppsala University in Sweden. "It\'s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they\'re stuck indoors. Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it\'s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it\'s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. To make electrochromic windows change color, what is applied to the window glass? 【单选题】

A. Electricity.

B.Tungsten oxide.

C.A battery.

D.A voltage.

正确答案:B

答案解析:第五段第二句提供了答案。a sheet of glass coated with thin layers of chemical compound such as tungsten oxide中的coated是“涂上一层薄薄的……”的意思。
