expect sb to do sth，跟allow很像；而expect that一件事的时候就不是关乎具体的人做事了。这里A和B的区别就是，不是女性被期待，而是大部分学生群体被期待

all you need to know, there, is that __ing modifiers have to adopt the timeframe of ... something in the sentence.
NOTHING in that sentence is happening in the same timeframe as "placing women...".
that placement is something that won't occur until well after everything else in the sentence -- many many years after these women are students.
since the __ing modifier doesn't share a timeframe with ANYTHING in the sentence ... it's wrong!

the majority of students entering law school this fall 和 trend 保持一致

d 同位语 a trend 的分词后置定语 placing，不能表现出即将发生的趋势，而是表达了一直发生的含 义;it is expected that...的表达不简洁。

,which 的用法不嚴謹。可以是women，可以是student，可以是前面一句話所表達的狀態。所以容易產生歧義。同位語的方式鎖定了含義。

ing的时态是跟随主句的。。。

D: illogical: the sentence means that the trend is "placing" the women in these positions right now (since the main clause is in the present).
-ING modifiers don't have a tense. they automatically adopt the tense of the clause to which they're attached.
E: incorrect. "which" can't modify the preceding sentence

A: wrong. the participle 'placing', which wrongly indicates that this trend is already placing more women in leadership positions.
C: wrong. the relative pronoun 'which' is placed in a position where it must refer to 'women'. this is wrong for 2 reasons: (a) 'which' can't refer to people, (b) according to the sentence, women don't place themselves in leadership positions; the trend does.

C为什么不对啊 毕老师

老师可以讲一下 “强调” 嘛？

placing和主句中的...expected to be...逻辑不符

A为什么不对啊……
