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
(A) the brain…无法与the production of…平行；growing使用错误,应该用grow的名词形式growth来替 换,increasing应该用increase替换;介词结构when placed无论是修饰主句的主语还是所修饰动词 (include)的逻辑主语,该结构都是修饰的documented examples,而从逻辑意思上看,when placed应该 修饰mice,因此when placed修饰对象错误. (D) when placed修饰documented examples,导致逻辑意思错误,代词they就近指代neurons,导致逻辑意思错误
when placed 不是应该修饰include句吗？那它怎么还能跑到前面修饰document呢？
