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

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~~

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?
