prep1-41详解

41.   (32917-!-item-!-188;#058&006462)

In the two years following the unification of Germany in 1989, the number of cars owned by residents of East Germany and the total distance traveled by cars in East Germany both increased by about 40 percent.  In those two years, however, the number of East German residents killed each year as car occupants in traffic accidents increased by about 300 percent.

Which of the following, if true, most helps to explain the disproportionate increase in traffic fatalities?

(A) The average number of passengers per car was higher in the years before unification than it was in the two years after.

(B) After unification, many people who had been living in East Germany relocated to West Germany.

(C) After unification, a smaller proportion of the cars being purchased by East German residents were used vehicles.

(D) Drivers who had driven little or not at all before 1989 accounted for much of the increase in the total distance traveled by cars.

(E) Over the same two-year period in East Germany, other road users, such as motorcyclists, bicyclists, and pedestrians, experienced only small increases in traffic fatalities.

看到CD上有解释,但是还是不明白,觉得不太靠谱. as car occupants是什么意思?是指汽车所有人吗?个人觉得A对,但是选项是D。比较郁闷!希望大家能帮我解答一下,谢谢!!!

我认为A是说乘客的年龄,所以不相关

MM

注意结论residents killed each year as car occupants 说的是车辆拥有者,A选项说的是乘客数量,是迷惑选项,乘客再多也无法解释为什么车主死的那么多。

D解释了这个discrepancy, 虽然total distance traveled by cars 仅增长了40%,但是中间大部分人都是新手,所以出事率很高,导致车主死亡率增长的十分惊人。

可是就算number of cars and total distance traveled by cars both increased 40%, 一个车主只能死一次阿,再怎么算,事故率不是也最多只有上升40%,怎么变成300%的?

汽车事故不一定是指人员死亡, 我就出过traffic accident, 但我还活着,呵呵。

不对啊,题目写着the number of East German residents killed each year as car occupants

嗯,楼上是对的, 那就是一个人开车,车里座着很多人, 结果出事故,车里所有的人都死了,哎。

增加的是个比例300%,想一下以前死者里面只有一个是车主,现在死车里面有4个就能是增加了300%了。不能把比例想成绝对数。所以题里的逻辑是对的,新手多了,车主出事的比例增加了,是可能出现虽然总数只增加40%,但是出事死亡率却增加300%的。

A错是因为它说反了。
如果可以解释这个矛盾的话,A应该是说:在unification之前乘车的人比unification之后的少,这样才能说明同样数量多的车出事故,为什么unification之后死亡人数上升了。
但是它现在的A说的是,unification之前的乘车人数比之后的多。

as car occupants,开车的人
作者: yangliuqing    时间: 2010-8-12 15:27
occupant 在这里的意思是a person who is in a building,car,etc at a particular time. car occupant即汽车乘员,而并非开车的人或车主

LS是正确的,longman也是这么说的。那就更不理解了~~问了NN懂了,因为是新手多了,所以事故死亡更高了而与总人数没关系
