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.
In the passage, it is implied that______.
选项 A、drinking should be restricted as severely for driving on water as on land
B、traffic signs should also be adopted on crowded waterways
C、speed limits should be set inside and outside harbor
D、a limited amount of alcohol is allowable for driving on water
答案A
解析 这是一道推断题。文中第三、四句说：“……在船上喝酒一般说来几乎是合法的。专家们说醉酒驾船也许比醉酒开车更危险。”文中接着说明了原因，即水上交通的完全无秩序、港口外对船速的无限制、水面波涛等因素的诱发作用。我们由此可以得出结论，既然醉酒驾船这么危险，就应当对此进行严格的限制。所以选项A正确。
