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
语义/核心词
主语 【 examples of neurogenesis, the production of new brain cells 】最近有文献记载的神经发生的例子，即新脑细胞的产生
所以后面的核心词肯定不是mice，也不是brain，ABC不行
D, canaries neurons learn 逻辑不对
If you say \"when + PAST PARTICIPLE\", then this automatically applies to the SUBJECT of the clause to which it\'s attached.
一看句首的不同，即知考察真正的主语。再通过逻辑推测，寻找真正的主语。划线部分明显两个句子明显对称，考察平行。
D省略不成立；题干同位语非必要不看。
sc
考察：
代词；；并列；
代词指代不清可以排除bcd
主句讨论的是生长现象，而不是器官brain，应该是brain growth，大脑生长；且brain growing ing形式怪怪的，正在生长的大脑？？ing修饰有时候比较尴尬，注意选择
If you say \"when + PAST PARTICIPLE\", then this automatically applies to the SUBJECT of the clause to which it\'s attached.
neurogenesis, 神经形成
a, neurogenesis include brain, 逻辑不对
b,neurogenesis include mice .. or canaries 逻辑不对
c, neurogenesis inlcude mice's brain.., or canaries' neurons that increase when they learn.. → canaries neurons learn 逻辑不对
d, canaries neurons learn 逻辑不对
A. growing错误，他可以是brain的定语，也可以是名词，同理increasing也错误；when placed就近修饰没有啥错误
B. they错误指代，且出现了不同指代的两个they
C. brains不能被placed
D. 第二个they所有格无指代
DE区别：E是定语从句，D如果when引导的定语从句，前面应该有when对应的时间名词，但并没有；引导时间状语从句，句子又不完整，错误
neurogenesis 神经系统发育后面应该include一个有想要逻辑的宾语，ABC excluded
D的结构没有E来的平行
D，when placed作伴随状语，逻辑主语是examples而不是mice，错误！
定语从句啊，傻了。。。。脑子不转了。。。
If you say \"when + PAST PARTICIPLE\", then this automatically applies to the SUBJECT of the clause to which it\'s attached.
when+现在or过去分词是伴随状语！不是就近修饰
D when placed修饰句子主语也就是examples，另外they指代不明，canaries‘ 变成所有格形式不能作为指代对象，这里指代的是neurons
选项中开头应该与the production of new brain cells平行
a选项growing应该替换成名词growth
bcd中最后一个they的指代都不明确，不知道是指代brains还是neurons
其中d选项when placed修饰了the brain growth，growth不能用place修饰，所以是错误的
答案选e
错选d，2、when+现在/过去分词是状语，逻辑主语是主句主语
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.
the production of new brain cells核心词是production，作neurogenesis的同位语，表示其本身就是生产的意思，后面的neurogenesis include mice/brains都是错的
A，mice when placed in a stimulating environment，从属连词when+分词既可以做定语也可以做状语，如：The bag which lies on the ground is hers. 这里when placed做定语修饰mice，ok，A的the brain growing错误，要在动名词前加逻辑主语只能用所有格，the brain‘s growing
E，限制性定语表示限制先行词的某个类别，mice that are placed in a stimulating environment，那些放在刺激性环境中的老鼠，canaries that learn new songs，那些学新歌的C，ok
D，in canaries' neurons when they learn new songs，they就近指代neurons而不是canaries
错选A，动名词高于doing！
NG的解释是production of cells，BC主语错。
D中they指代不明。
