问题     With oil prices and interest rates low, more and more Americans are buying boats—and as traffic on the waterways increases, so does the number of accidents from drinking and driving on water. A National Transportation Safety Board study concludes that drinking may be a factor in 80 percent of the 1 000 or so deaths in boating accidents that occur every year. Yet anyone can drive a boat without a license (执照), drinking on board is almost universally legal. Experts say drunken boating may be even more dangerous than drunken driving. Boating on a crowded waterway can be in complete disorder: there are no stop signs, traffic lights or lane markers. Speed restrictions are nonexistent outside harbors. Some boats have terrible power and top speeds—and no boat has brakes. Combined with the effects of all the sun, wind, waves and happy tiredness that go with boating, even moderate amounts of alcohol can be dangerous. According to one recent study, a boater’s judgement and behavior can be worsened by only about a third as much alcohol as it would take on land. Only recently have many states begun to take action against drunken boating. The key is passing laws to set a medical standard for blood alcohol level and to allow police to test blood-alcohol levels on the spot. Increasingly, speed restrictions are also be-ing set on crowded waterways. Some experts also suggest granting licenses for boat operators. The license requirement could be used to strengthen safety training and to keep repeat offenders off the water. It would also make it harder for beginners and children to go joyriding in high-performance boats.
Why is drunken boating more dangerous than drunken driving?
选项 A、Because of the enjoyment of boating.
B、Because of the terrible power and high speed.
C、Because of the crowded waterways.
D、Because of the lack of traffic regulations.
答案D
解析 文中第五句说：“在一条拥挤的水道上驾船会处在一种完全无秩序的状况下：没有停止信号、交通灯或通路标志。”由此我们可以得出醉酒驾船比醉酒开车更危险的原因是：水上缺乏交通规则，而陆上有交通规则。选项A“原因是驾船享受”与文章内容不符；选项B“原因是令人可怕的动力和高速度”，文中说一些船有令人可怕的动力和高速度，而且船都没有制动器，这一点只是水上驾船危险的原因之一，不是同醉酒开车相比醉酒驾船更危险的原因；选项C“原因是拥挤的水道”同样不符合题意。
