Questions 27～31 are based on the following passage. Drunken driving -- sometimes called A

merica's socially accepted form. of murder -- has become a national epidemic. Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past decade.

A drunken driver is usually defined as one with a 0. 10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American man image and judges were tolerant in most courts, but the drunken slaughter (屠杀) has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant.

Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18 to 20-year-old drivers more than doubled, so the state recently upped it back to 21.

Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop "responsible attitudes" about drinking and teach them to resist pressure to drink.

New laws have led to increased arrests and tests and, in many areas already, to a marked de- dine in fatalities. Some states are also penalizing bars for serving customers too many drinks. A tavern (小酒店) in Massachusetts was fined for serving six or more double brandies to a customer who was "obviously intoxicated (喝醉的)" and later drove off the road, killing a nine-year-old boy. As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919, what President Hoover called the "noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.
