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.About drink driving, the authｏｒwarns 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 ｏｒkill 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。

3、Ten years after the event, her death still remains a puzzle.【单选题】

A.mist

B.fog

C.secret

D.mystery

正确答案:D

答案解析:事情发生10年后，她的死因仍是个谜。本题难度较大，干扰项干扰很强，主要是C项。puzzle指“困惑，不解之谜”，和mystery“神秘的”是近义词，都是指人们还暂时没有揭开谜团。C项secret指“秘密”，是指一部分人已知道真相，所以和puzzle，mystery是有区别的，最佳答案是D。

4、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age. The finding, published in the April 3 issue of Science, could open a new path fｏｒthe treatment of heart diseases such as heart failure ａｎｄ　heart attack, experts say. "We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professｏｒof stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with ｏｒif they could be renewed," he said. The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover rate decreases with age to only 0. 45 percent by age 75, "If we can understａｎｄ　how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals that promote this process to stimulate regeneration after fｏｒexample, a heart attack, "Frisen said. That could lead to treatment that helps restore damaged hearts. A lot of people suffer from chronic heart failure," noted co-authｏｒDr. Ratan Bhardwaj. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said. With this finding, scientists are "opening the doｏｒto potential therapies to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new ａｎｄ　more cells to overcome the problem they are facing. " But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.In people in their mid-70s, only 0.45 percent of cardiomyocytes ____.【单选题】

A.are still functional

B.are reduced each year

C.are replaced each year

D.are damaged each year

正确答案:C

答案解析:第四段说，一个人20岁时，其每年被更替的心肌细胞为1%，随着年龄的增长，该更替率( turnover rate)不断下降，等到75岁时，只有0. 45%。
