标题: PREP1-Q18~再次麻烦NN们~ [打印本页] 作者: evelyn205205 时间: 2011-7-24 10:46 标题: PREP1-Q18~再次麻烦NN们~ Many small roads do not have painted markings along their edges. Clear edge markings would make it easier for drivers to see upcoming curves and to judge the car's position on the road, particularly when visibility is poor, and would therefore seem to be a useful contribution to road safety.However, after Greatwater County painted edge markings on all its narrow, winding roads, the annual accident rate along those roads actually increased slightly. Which of the following, if true, most helps to explain the increase in accident rate?
(A) Greatwater County has an unusually high proportion of narrow, winding roads. (B) In bad weather it can be nearly as difficult for drivers to see the road as it is at night. (C) Prior to the painting of the edge markings, Greatwater County 's narrow, winding roads already had a somewhat higher accident rate than other Greatwater County roads. (D) Many of the accidents on narrow, winding roads involve a single vehicle veering off the road, rather than the collision of two vehicles. (E) After the markings were painted on the roads, many drivers who had gone out of their way to avoid driving on those roads at night no longer did so.
答案：E。我觉得B也对嘛，NN们哦，问一下哈，B错在哪里啊？作者: 祝歌靓 时间: 2011-7-24 11:32
B说在不好的天气里，司机就像在晚上开车一样看不见路。 但是原文中的issue是clear edge marking并没有起到想象中的作用，其限制是narrow,windind road，因此必然是其他原因导致了在又窄又弯曲的道路上交通事故略幅上升的原因，B把限制点定位在bad wether 明显和原题不符。 it is my opinion........作者: evelyn205205 时间: 2011-7-24 15:47
恩，非常感谢你的解释！ 也就是说，这是一道偷换概念的题咯，明明说的small roads，最后却把矛头指向另外一个roads，于是这个就是解释点。
