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.
the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that
mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they
mice's brains that grow when they are placed in a stimulating environment or canaries' neurons that increase when they
the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they
brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that
If you say \"when + PAST PARTICIPLE\", then this automatically applies to the SUBJECT of the clause to which it\'s attached.
，即主语examples，而并不是语义上的mice，所以AD错误
D的they指代也错了，Ron原话：
"they" is totally wrong in (d). it would automatically refer to "neurons", since "canaries' " is possessive and therefore ineligible to be the referent.
D 错在they 指代错误，应该指代动物，但指代成了动物的神经元
they指代canaries，when canaries learn new song的神经元增长，没有不对
但也确实可以指代神经元s，存在指代不清的问题登录 或 注册 后可以参加讨论
D 错在they 无指代
句子主干 Examples include brain growth…and an increase in neurons…

故后面的主语应该是growth，而不是mice或者brain
D选项when placed in a stimulating environment的主语是brain growth，错误

neurogenesis的例子不应该Include是动物（mice等）或brain，应该是一个过程，因此不优选ABC
BC、They中途换了指代对象，WRONG
D、when placed中间省略的只能是主句主语，即examples，在这里肯定不对（AD）；而且所有格canaries‘不能用They代指（CD）

And the other thing wrong with A, B, C and D is "when placed in a stimulating environment" - it sounds like they are referring only to the time that the mice are in the stimulating environment - but the brain growth is permanent. It doesn't shrink back down once the mice are no longer in the stimulating environment. Ditto for the increase in neurons in the canaries.
CHOICE E：“the brain growth in mice" ---"an increase in neurons in canaries" 平行，，找核心词 “growth” --- "increase"
If you say \"when + PAST PARTICIPLE\", then this automatically applies to the SUBJECT of the clause to which it\'s attached.
if i say
iron accumulates rust when submerged in water
then it\'s the iron, not the rust, that\'s submerged in water.
this strikes choice (d), since the SUBJECT is \"recently documented examples\", not \"mice\" as required.
if i say
iron accumulates rust when submerged in water
then it's the iron, not the rust, that's submerged in water.
Moreover, neurons cannot learn!
