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.

Examples of Neurogenesis can only be an activity
D when placed连词+过去跟词作伴随状语,用主句的主语,主句的主语是examples,examples不能placed in……,是rice placed in……,D错
1,动词有action noun形式时,不要用complex gerund来表示动词的名词形式,比如growth,不要用the growing
更正:动词有action noun形式时,不要用complex gerund来表示动词的名词形式,比如growth,不要用the growing
A的错误在动名词本身是名词,前面不再带名词构成某人的做某事,如果要表示某人的做某事,用名词所有格
A改成the brain‘s growing or the neurons’ increasing
1,动词有action noun形式时,不要用complex gerund来表示动词的名词形式,比如growth,不要用the growing
2、when+现在/过去分词是状语,逻辑主语是主句主语
3、neurogenesis是神经发生,神经形成的意思,the production of new brain cells指新细胞的产生,production,产品,也可以指生产,产生
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.
针对D,我不认为错误的原因在于when placed的逻辑主语错误。
when placed in a stimulating environment是状语从句的省略,变化为过去分词的形式,因此'placed in a stimulating environment'过去分词就近修饰名词mice
D最大的问题在于they的指代不清晰,有歧义地指代了neuron
when+过去分词的默认主语是主句主语
D中when placed in a stimulating environment & when they learn new songs都是状语,修饰的是动作,即主句的动词,当时间状语,这个意思就不对了,它不是用来修饰动词的
Ron 关于d 的解释,超棒!!

D中when是省略主语的,可以理解为anything,老鼠的大脑增长并不是把任意东西放在刺激环境中都会发生的,只有把老鼠放进去才会发生。
注意同位语,production应该是brain growth和increase in neurons

the brain growth 和 the increase 才可以和前面的N(一种production)平行。 重点是production、
总是忘记还原状语从句省略的主语 也总是忘记check代词指代的单复数是否一致!
A: when placed的逻辑主语是production而不是邻近的mice,句意错;动名词growing和increasing应该改成名词growth,increase
B: they指代不明,可以指代brains或mice;第二个they和第一个they不是一个对象
其实只有that没有指代不明,就近修饰mice
C: they指代brains不对;第二个they和第一个they不是一个对象
D: when placed的逻辑主语是production而不是邻近的mice,句意错;
E: correct

注:对于动物用that不用who
但是whose可以指代物也可以指代人

用了when主语就变了,但主语必须不是动物本身
