1、Flu doesScratchy throats, stuffy noses ａｎｄ　body aches all spell misery, but being able to tell if the cause is a cold ｏｒflu may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds ａｎｄ　the flu, ａｎｄ　one of the keys is being able to quickly tell the two apart. That\'s because the prescription drugs available fｏｒthe flu need to be taken soon after the illness sets in. As fｏｒcolds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold ａｎｄ　the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses-flu A, B ａｎｄ　C. There is no cure fｏｒeither illness, but the flu can be prevented by the flu vaccine (疫苗), which is, fｏｒmost people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu ａｎｄ　common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose ａｎｄ　scratchy throat typically develop gradually, ａｎｄ　adults ａｎｄ　teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu fｏｒall ages. ａｎｄ　in general, flu symptoms including fever ａｎｄ　chills, sore throat ａｎｄ　body aches come on suddenly ａｎｄ　are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants ａｎｄ　preschool age children have the flu. It advises parents to call the doctｏｒif their small children have flu-like symptoms.Both cold ａｎｄ　flu symptoms can be eased with over-the-counter medications as well. However, children ａｎｄ　teens with a cold ｏｒflu should not take aspirin fｏｒpain relief because of the risk of Reye syndrome (综合症), a rare but serious condition of the liver ａｎｄ　central nervous system.There is, of course, no vaccine fｏｒthe common cold but frequent hａｎｄ　washing ａｎｄ　avoiding close contact with people who have colds can reduce the likelihood of catching one.If children have flu-like symptoms, their parents ____.【单选题】

A.are advised not to give them aspirin

B.should watch out fｏｒsigns of Reye syndrome

C.are encouraged to take them to hospital fｏｒvaccination

D.should prevent them from mixing with people running a fever

正确答案:A

答案解析:第七段第二句直接指明了：儿童和十多岁的孩子不能服用阿司匹林来缓解伤风流感带来的疼痛，因为这有可能导致Reye综合症，会使肝脏和中枢神经系统处于少见的严重状态。

2、Driving after drinkingThe legal ｌｉｍｉｔfｏｒdriving after drinking alcohol is 80 milligrams of alcohol in 100 millilitres of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, what you\'ve just eaten ａｎｄ　what sort of drinks you\'ve had. Some people might reach their ｌｉｍｉｔafter only about three standard drinks.In fact, your driving ability can be affected by just one ｏｒtwo drinks. Even if you\'re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.It takes about an hour fｏｒthe body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking in the evening you might find that your driving ability is still affected the next morning, ｏｒyou could even find that you\'re still over the legal limit. In addition, if you\'ve had a few drinks at lunchtime, another one ｏｒtwo drinks in the early evening may well put you over the legal limit.In a test with professional drivers, the more alcoholic drinks they had had, the more certain they were that they could drive a test course through a ｓｅｔof movable posts…ａｎｄ　the less able they were to do it! So the only way to be sure you\'re safe is not to drink at all.Alcohol is a majｏｒcause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, ａｎｄ　road accidents after drinking are the biggest cause of death among young men. More than half of the people stopped by the police to take a breath test have a blood alcohol concentration of more than twice the legal limit.It is important to remember that driving after you\'ve been drinking doesn\'t just affect you. If you\'re involved in an accident it affects a lot of other people as well, not least the person you might kill ｏｒinjure.You might be accused of drunk driving when____.【单选题】

A.you drive upon having some drinks

B.you become a helpless alcohol addict

C.your driving is found abnormal fｏｒdrinking

D.your alcohol percentage fails the test

正确答案:C

答案解析:细节考查题。题干“你可能会被指控醉酒驾驶”是对第二段第二句you could still be taken to court的同义改写，因此应参考该句的后半部分“if a police officer thinks your driving has been affected by alcohol”（如果警官认为酒精已对你的驾驶产生影响），故正确答案为C。

3、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 ｏｒcell that causes the problem ａｎｄ　finds ways to effectively kill ｏｒcontain it. In the most serious of cases, in which the entire population of a region ｏｒcountry 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 ｏｒdisease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak ｏｒdead 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 fｏｒthe 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 authｏｒin writing this passage is____.【单选题】

A.to comment ａｎｄ　criticize

B.to demonstrate ａｎｄ　argue

C.to interest ａｎｄ　entertain

D.to explain ａｎｄ　inform

正确答案:D

答案解析:主旨题。题干考查的是作者写作本文的目的。通过阅读整篇文章可以看出，作者的语气是客观的，主要是解释和说明信息。选项D与此相符合，故正确答案为D。选项A和B属于议论文的目的。本文是科普性文章，因此选项C“为了引起关注和娱乐”也不符合题意。

4、The Only Way Is Up Think of a modem city ａｎｄ　the first image that come to mind is the skyline. It is full of great buildings, pointing like fingers to heaven. It is true that some cities don\'t permit buildings to go above a certain height. But these are cities concerned with the past. The first thing any city does when it wants to tell the world that it has arrived is to build skyscrapers. When people gather together in cities, they create a demａｎｄ　fｏｒlａｎｄ　since cities are places where money is made, that demａｎｄ　can be met. ａｎｄ　the best way to make money out of city lａｎｄ　is to put as many people as possible in a space that covers the smallest amount of ground that means building upwards. The technology existed to do this as early as the 19th century. But the height of buildings was limited by one important factor. They had to be small enough fｏｒpeople on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, ｏｒhome. Elisha Otis, a US inventor, was the man who brought us the lift ｏｒelevator, as he preferred to call it. However, most of the technology is very old lifts work using the same pulley system the Egyptians used to create the Pyramids. What Otis did was attach the system to a steam engine ａｎｄ　develop the elevatｏｒbrake, which stops the lift falling if the cords that hold it up are broken. It was this that did the most to gain public confidence in the new invention. In fact, he spent a number of years exhibiting lifts at fairgrounds, giving people the chance to try them out before selling the idea to architects ａｎｄ　builders. A lift would not be a very good theme park attraction now. Going in a lift is such an everyday thing that it would just be boring. Yet psychologists ａｎｄ　others who study human behaviｏｒfind lifts fascinating. The reason is simple. Scientists have always studied animals in zoos. The nearest they can get to that with humans is in observing them in lifts. "It breaks all the usual conventions about the bubble of personal space we carry around with us ａｎｄ　you just can\'t choose to move away," says workplace psychologist, Gary Fitzgibbon. Being trapped in this setting can create different types of tensions, he says. Some people are scared of them. Others use them as an opportunity to get close to the boss. Some stａｎｄ　close to the door. Others hide in the comers. Most people try ａｎｄ　shrink into the background but some behave in a way that makes others notice them. There are a few people who just stａｎｄ　in a comer taking notes. Don\'t worry about them. They are probably from a university.Psychologists find the lift a good place where they can study human behaviｏｒbecause____.【单选题】

A.here humans behave the way animals do

B.people in a lift are all scared

C.here some people take notes

D.in a lift the bubble of personal space breaks

正确答案:D

答案解析:电梯的空间狭小，相对拥挤，人们想要享有私人空间的要求在这里成了幻想，如同关在动物园的笼子里的动物一般，这为心理学家提供了一个研究在这种情况下人的行为的难得的机会。

5、Smart Window Windows not only let light in to cut down an electricity use fｏｒlighting, 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 professｏｒof 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 fｏｒimproving 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 majｏｒfocus of energy research fｏｒa long time. Over the years, scientists have come up with a variety of strategies fｏｒcoating, 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. Fｏｒexample, 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 ｏｒdark. 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. What are smart windows, according to Paragraph 4? 【单选题】

A.Windows that are coated.

B.Windows that are glazed.

C.Windows the colｏｒof which can be changed.

D.Windows that have many layers.

正确答案:C

答案解析:第四段告诉我们，多年来科学家已研究出多种通过窗户节能的办法，而smart windows使用的技术使窗户能变换颜色，所以C是正确选择。
