GWD21-Q30 （TN版-15）

30. GWD21-Q30:

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars.  Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow.  The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

 

A.      A few children still use traditional wooden sleds.

B.       Very few children wear any kind of protective gear, such as helmets, while sledding.

C.      Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.

D.      Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled.

E.       Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

正确答案为C

这题看的不大明白，因为10年前用的是塑料滑板，过去用的是木质滑板，到底他们的关系是什么？谁前谁后？

还有最好一句话也没看懂……

请帮忙分析一下，谢谢……

题干的推理过程大概是:N前用木制滑雪板,但10年之前(发生在木制之后)改称塑料的了----塑料的比木头的危险----因为现在滑雪受伤的小孩比10年前多了(也就是采用塑料板之前)

时间轴是:

------------木制---------------塑料-----------------

------------很久以前----------10年前--------现在----

选C的原因是引入他因.C说塑料板的使用范围广,也就是说,使用范围广泛----滑雪次数增加----受伤人数增加,而不一定是由本身安全性引起

这道题目这么解释根本就是太牵强了。对不起。

说塑料的用途广泛并不代表用的人就多呀，这样解释是不对的。

而且为什么有人说答案是D?

顶上来看有否大牛来解释。

哦，在补充一点，可以用在更加多的snow condition上，受伤的孩子也更多，对于母亲来讲，当然认为塑料的更加危险，所以C绝对不是weaken.
