问题     The legal limit for driving after drinking is 80 milligrams of alcohol in 100 milliliters of blood in the U.S. 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, sex, and the sort of drinks you have 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 can 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 heavy drinking in the evening, you might find that your driving ability is still affected next morning, or you could even find that you are still over the legal limit. In addition, if you have 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 through a set of moveable posts in the driving test…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 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 people. More than half of the people stopped by the police to take a breath analyzer test have a blood alcohol concentration of twice more than the legal limit.
    It is important to remember that driving after drinking doesn’t just affect yourself. If you are involved in an accident, it affects a lot of other people as well, not least the persons you might injure or kill.
Alcohol is a major cause of road accidents in that________.
选项 A、all drivers who die in these accidents have been drinking
B、more people die in drink-related accidents than in any other way
C、drinking affects people’s blood alcohol concentration
D、one in three of the drivers drink heavily
答案B
解析 根据第五段前两句“Alcohol is a major cause of road 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 people. ”可知，酒是交通事故的主要原因；在交通事故中丧生的司机中有三分之一体内酒精含量超出法定上限，饮酒导致的交通事故是人们死亡的最主要原因。由此可推知，酒是交通事故的一个主要原因就是与其他丧生方式相比，更多人死于与酒有关的事故。故选B。
