标题: PREP-1-64

64.   (27947-!-item-!-188;#058&003452)

Recently documented examples of neurogenesis, the production of new brain cells, include the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that learn new songs.

(A) the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that

(B) mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they

(C) mice's brains that grow when they are placed in a stimulating environment or canaries' neurons that increase when they

(D) the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they

(E) brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that

答案E.

请问解题思路?

自己解:

ABCD的when引导的状语从句有错误,是修饰主句的.所以要修饰mice只能用that从句.

这道题我的分析思路:

1#同意楼上的,时间状语从句的逻辑主语指向句子的主语,但是这里的when引导的从句的主语很明显不能是the production of new brain cells

2# 句子中 the production of new brain cells, include.... ; include 后面的内容应该是the production of new brain cells 的一种,从意思上分析肯定不能是 A B C 中的 the brain / mice / mice's brains.

3# 结合1# & 2# ,答案只能是 E 。 但是E 也有些瑕疵:

    A. an increase in neurons in canaries that learn new songs. 这里面的that 要指向谁,从意思分析只能是neurons,也就是这里有一个 that 从句的跳跃修饰问题。通常这类跳跃修饰 GMAT 会用 从句的谓语动词单复数 ( learn) 来消除歧义,但是这里 canaries / neurons 都是复数名词,无法削除歧义。

   B. brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that    E 中的平行  brain 前面没有冠词, 而increase 前面有 an ,感觉不太好。相比之下,D 中的平行从形式上更加工整:the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they。 如果不分析逻辑意思,单从形式平行上看 D 更好。 当然 D 还有一个 they 的指代模糊问题。

从这道题来看,大N 们强调的逻辑意思为先表现的淋漓尽致。ETS是越来越狡猾了。

个人观点,欢迎拍砖!

说的好! 其实用when的状语修饰错误这一点就可以排除ABCD了
