[讨论]真题21－30[

30.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 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.

答案C,
我选E

我觉得应该是C。 C表明使用plastic ones 的人数远远大于wooden 的，那么受伤人数多也是自然的呀。

这句话的意思是“去年冬天(用wood)的sledding受伤人数多于十年前（用plastic),所以说plastic sleds more dangerous不对”
C“使用越多”和“出事故越多”在文章没说明的情况下并没有必然联系，应该是无关选项。

我认为是C。因为Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can。即塑料雪橇可以去更多，更复杂容易出事的地方。所以可以消弱。E明显有增强的味道。因为由此可推 实际木雪橇出事的比例更小。

不好意思，你们是对的，是我看错了mood和plastic的出现先后顺序了。

E的确是strengthen结论的，ft，我刚开始看也误选e了，嗨，都快考了，怎么对结论还是不够敏感呢？主呀，保佑我在考试的时候一定一定要对结论敏感一些呀！
