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.
Another effective measure suggested against accidents is______.
选项 A、to issue license
B、to prevent beginners from driving boats
C、to keep offenders off the water
D、to prevent people from riding boats in bad weather
答案A
解析 文中倒数第三句说：“一些专家也建议为驾船者颁发执照。”所以选项A正确。选项B“防止初学者驾船”和选项C“使惯犯远离水面”都是颁发执照能产生的预期效果，而不是采取的有效手段；选项D“防止人们在恶劣的天气驾船”在文中没有提及。
