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 canariesthat 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 tha

这题选E,我想问如果这道题把D改为the brain growth in mice when it is placed in a stimulating environment or the increase in canaries'neurons when they是不是就对了呢?而且要比E更好些呢?谢谢~~

回楼上，确实有点这方面的歧义，when也能理解成主句的一个时间状语,但是有点牵强...不过读的时候确实感觉有修饰主语的意思，其实主要错误还是强加了when这个关系吧

今天做到了这个题,看了解释后我是这样理解的
主语是examples of neurogenesis,谓语是include;而the production of new brain cells是neurogenesis的同位语,意思是新的大脑细胞的生成,因此include的宾语都应该举大脑细胞生成的例子,而ABC都说的是大脑,所以不对
D里面in canaries' neurons when they learn new songs.when they的they就近指neurons不对
因此选E
但是我使终不明白对D的解释里说"when placed" modifies "documented examples"...请NN们帮忙看一下好吗?

the increase in canaries'neurons when they they就近修饰neurons所以不对
