[求助]天山7-32

Q32:

The town of Enderton is located in an area where forest fires are quite common. During dry periods and periods of persistent winds, when even a spark can result in a fire that spreads over many acres, the danger of fire there is particularly serious. To help prevent forest fires in the area, the town government plans to post a ban on outdoor fires when such conditions prevail.

Which of the following, if true, provides the strongest indication that the town’s plan will have at most a minor effect on the annual number of forest fires in the Enderton area?

A. Most of the tourists who visit the forests surrounding Enderton also visit Enderton itself.

B. Although there are county fire fighters available to combat forest fires in the area, Enderton itself has no professional fire fighters.

C. Very few forest fires in the Enderton area result from fires deliberately set by

arsonists.

D. Nearly all forest fires in the Enderton area are the result of lightning strikes.

E. The number of forest fires in the Enderton area has not increased significantly in the last several years.

题目的答案是D。

我选得是C,其实c我也是觉得没有别的可以适合的才选的。

我理解题目问的是:什么使计划的实施效果最差?

可是如果选D的话要一个前提是lightning strikes 是在室内阿。

想不通了。

大家帮帮我好不?谢谢

阿,那么也就是说看d的时候就想着是室内的就可以了对吧?觉得选不出来的时候就选一个相对正确的选项。

题目要求weaken这个镇政府提出的proposal,问什么情况可以使得这个proposal对于E这个地方的森林火灾数目的控制作用最小,其实也就是要weaken。

proposal说当天气干燥和风很大时,禁止户外生火,也就是说禁止户外的火源。如果要削弱这个计划,那么就是说禁止户外火不一定能控制森林火灾数目,有可能E这个地方的森林火灾就不是又户外的火源引起的,所以禁止户外火也不能减少火灾。这是在读完题后自己的想法。

C说E这个地方很少的森林火灾是有人故意纵火的。那么如果大部分森林火灾是人们去郊游不小心留下的火源呢,这样一来,禁止户外生火还是有用的,不能weaken这个计划。

D说几乎所有的森林火灾都是由lightning strikes导致的,是户内的火源。所以政府禁止户外生火根本没办法去除户内的火源。也就weaken了计划。
