试题详情

题目:

Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane. In many nearby towns, speed humps (raised areas of pavement placed across residential streets, about 300 feet apart) have reduced traffic speeds on residential streets by 20 to 25 percent. In order to reduce traffic speed and thereby enhance safety in residential neighborhoods, Ardane's transportation commission plans to install multiple speed humps in those neighborhoods.

Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?

选项:

A、On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.
B、Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps.
C、The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed.
D、Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators.
E、Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps.

答案:

B

提问:

文章关注的是限速进而减少危险,b选项关注的不是速度问题是一些特殊车辆要减速的问题,而这些问题不是由速度引起的是耽误了救援,而我选择的D当时的思路是,开汽车的人没有意识到减速带就不会减速,就不能减速进而减少安全问题起到了weaken的作用@英吉老师

提问陆旭老师:这题虽然是个中库题,但我觉得正确选项B有点牵强。虽然题目是说到要enhance safety,但B选项说得没那么直接,得靠你自己推出来就是这些减速带可能会延缓救援时间。我选的是D,不过我知道D后半句说的很奇怪,它讲了一个条件,就是要有warning signs。不过我选D主要是觉得D前半句说得挺不错的。OG上说D是错的,因为“This is unlikely to be a drawback, since warning signs are typically put in place whenever speed pumps are installed”,但我觉得OG解释的好像也不是很好。我想请老师帮我分析分析这题。

提问:

b说的是ambulances这种车必须降速吗?可是原文说这个speed hump的作用就是让车降速啊,那这不就刚好符合了嘛?还有为什么不选e呢?
