原题如下:
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. -------------------------------------------------------------------- 这个题的标准答案是C。 而基于如下分析:十年前塑料雪橇开始流行——比木质雪橇更快更难以驾驶——去年冬天儿童玩雪橇受伤数字高于10年前——结论:塑料雪橇比木质雪橇更危险。 问如何weaken。 看来看去,似乎E比C更有说服力,C提到塑料雪橇比木雪橇可用于更多的雪地状况;而C说的是木雪橇的危险之处在于如果出意外可能会伤及更多的儿童,直接挑战了原题premise中关于伤亡数字的部分,所以。 一家之言,还请大家讨论,指点!
