问题     There is extraordinary exposure in the United States to the risks of injury and death from motor vehicle accidents. More than 80 percent of all households own passenger cars or light trucks and each of these is driven an average of more than 11,000 miles each year. Almost one-half of fatally injured drivers have a blood alcohol concentration (BAC) of 0.1 percent or higher. For the average adult, over five ounces of 80 proof spirits would have to be consumed over a short period of time to attain these levels. One third of drivers who have been drinking, but fewer than 4 percent of all drivers, demonstrate these levels. Although less than 1 percent of drives with BACs of 0.1 percent or more are involved in fatal crashed, the probability of their involvements is 27 times higher than for those without alcohol in their blood. There are a number of different approaches to reducing injuries in which drinking plays a role. Based on the observation that excessive consumption correlates with the total alcohol consumption of the country’s population, it has been suggested that higher taxes on alcohol would reduce both. While the heaviest drinkers would be taxed the most, anyone who drinks at all would be punished by this approach.
    To make drinking and driving a criminal offense is an approach directed only at drinking drivers. In some states, the law empowers police to request breath tests of drivers committing any traffic offense and higher BAC can be basis for arrest. The National Highway Traffic Safety Administration estimates, however, that even with increased arrests, there are about 700 violations for every arrest. At this level there is little evidence that laws are effective ways to reduce drunk driving. In Britain, motor vehicle accidents fell 25 percent immediately following implementation of he Road Safety Act in 1967. As Britishers increasingly recognized that they could drink and not be stopped, the effectiveness declined, although in the following three years the death-rate seldom reached that observed in the seven years prior to the Act.
    Whether penalties for driving with a high BAC or excessive taxation on consumption of alcoholic drink will deter the excessive drinker responsible for most accidents is unclear. One thing is clear, however, unless we deal with automobile and highway safety and reduce accidents in which alcoholic drinking plays a role, many will continue to die.
选项 A、interpreting the results of surveys on traffic accidents
B、reviewing the effectiveness of attempts to reduce drank driving
C、analyzing the causes of the large number of annual traffic deaths
D、making an international comparison of experience with drank driving
答案B
解析 本文最后一句点明了主题：然而，有一点很清楚，除非我们关注汽车和高速公路的安全问题，减少因饮酒而发生的交通事故，否则更多的人将会死去。作者在全篇文章中主要讨论了饮酒和交通事故之间的关系以及如何限制酒后驾车。
