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?

  c

• 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.

第一题：C选项问题出在exceeds that which，不知道that指代什么，而且which从句修饰that有很wordy。
第三题：在XXX速度要用at，排除AB；比较级higher这里应该用than，排除D； than that currently possible要是省略就应该把that省掉，留着that留着currently possible把中间谓语省了，不像话，排除。

第二题是逻辑题发到CR区给你看吧。
最好说一下具体哪里有疑问。











我就是懒得分析5个CR选项，哼.................

不知道that指代什么————= =|||我不是问你，我是说这里指代关系有错。不知所云。

排除掉ABCD后E是剩下最好的，不代表E是完美的。
不是很有必要讨论怎么改或者怎么补全。

可以这么补at speeds (that would be) much higher than (speeds that) are currently possible
你可以觉得别的补全的方法更好，但是那全都是题外话，跟做题没什么关系。

doubling that of the increase in

twice as many as the increase in

还有一题，真的是完全搞不明白twice 和double的区别到底何在？并且double修饰时到底是现在分词形式还是过去 ...

twice as many as ：由于是many，前后比较的显然应该是可数名词的个数。这里as后面加的是increase，而不是people——排除。

double可以做形容词可以做动词可以做副词可以做名词
但是double as much as显然是扯淡的，要用twice才对——排除

剩下两个“逗号”+doubling，显然是动词的现在分词，所以在句子中做状语修饰整句/或者说谓语。
问题是B中increase已经是个数字了，that of the increase说不通是个什么意思。

选A
