1、Driving after drinkingThe legal limit for driving 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 limit after only about three standard drinks.In fact, your driving ability can be affected by just one or two 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 for the 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, or you could even find that you\'re still over the legal limit. In addition, if you\'ve had a few drinks at lunchtime, another one or two 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 set of 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 major cause 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 or injure.About drink driving, the author warns you of the fact that you____.【单选题】

A.may be taken to court by the police

B.are putting yourself in danger

C.may hurt or kill another driver

D.are setting other people at risk

正确答案:D

答案解析:态度题。答案参见最后一段：酒后驾车不单单影响你本人，如果发生事故还会影响其他许多人，尤其是你可能撞死或撞伤的那个人。故正确答案为D。

2、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. What will be the benefit if the research on smart windows turns out to be successful, according to the last paragraph? 【单选题】

A.The buildings will look different.

B.Windows can be as large as you want.

C.We may not need air conditioners any more.

D.They are less expensive than traditional windows.

4、Gun Rights in the US Immediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president and the state governor both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons. Strictly speaking, the US is not the only country where gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seems unwilling and politically incapable of doing anything serious to stop it. In countries like Britain and Canada. The government adopted stricter gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby and the electoral system. The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun controls anyway. ____ the years, the Democrats have found that they can either campaign for gun control or win power, not both; they prefer power. According to the US Bureau of Justice Statistics, firearm incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don\'t want to give up their arms they keep to protect themselves. Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professor in Virginia incident had been carrying a legal weapon they might have been able to stop all this. " In his opinion, the massacre is an argument for more people to carry, weapons, not fewer. But at the root of Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK\'s Guardian newspaper. One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American\'s responsibility to have a gun. "Each person," he said, "should not rely solely on the government for protection. " 【单选题】

A.Over

B.Since

C.Till

D.Until

A.ceremony

B.funeral

C.tears

D.grief

正确答案:D

答案解析:前句提到，人们聚集在一起为死者默哀，后句应该是： 总统和州长匆匆前往与大家同悲。share是分享的意思，我们可以说share sth. （分享一件东西），也可以说：share happiness（分享快乐），即，跟他人有同样的感情。所以本题应选：grief= sadness，share grief（同其他人一样感到伤心、难过）。
