15. Recently documented examples of neurogenesis（神经形成）, 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

E中的neurons in canaries that learn new songs中的that能修饰canaries 特高频噪声么？？

特高频噪声学习新歌的时候？？？这什么逻辑阿？

D中they指代neurons，neurons怎么earn new songs？

canary是金丝雀啊，复数而已，不是高频噪声啊

还是不理解DE之间的问题。

D中when placed 是省略主语，那么逻辑主语就该是主句的主语production 了，所以不对。

但是后面的they没有指代对象，因为不能指代canaries。不知道这么理解对不对？？？

但是E中的that修饰什么？mice？that可以修饰介词短语中的名词吗？不懂：（

選E..mice後面的that就很清楚的形容是mice被放在stimulating environment符合邏輯..

d中的when place是指brain,当然不合适。

我认为这句话的结构是这样的：，include（brain growth in mice that are placed in a stimulating environment） or （an increase in neurons in canaries thatlearn new songs.）

这里the brain growth in mice 和an increse in neurous in canaries(金丝雀的复数）是很并列的，两个that分别修饰mice和canaries

只是第一次见include or的用法
