[讨论]prep8 同位语如何修饰主句

8 Women are expected to be the majority of student entering law school this fall, a trend ultimately placing more women in leadership position in politics and business.

A  Women are expected to be the majority of student entering law school this fall, a trend ultimately placing

B  The majority of students entering law school this fall are expected to be women, a trend that will ultimately place

C  The majority of students entering law school this fall are expected to be women, which will ultimately place

D  It is expected that the majority of students entering law school this fall will be women, a trend ultimately placing

E  It is expected for the women to be the majority of students entering law school this fall, which will ultimately place

notes的解释如下： 

A: 同位语的placing结构，不能表现出即将发生的趋势，而是一直发生的

B: correct，用that定语从句修饰trend，清晰表明了要发生的动作

C: which无指代

D: 同A

E: 同C

注意：

1、which和同位语结构同时出现，表明应该用同位语结构，因为which指代前面整个句子错；

2、分词和that从句同时修饰一个名词，要看从句是否有表达分词不能表达的逻辑含义，如果是则选从句，反之选分词修饰更加简洁

我有一点疑问，难道同位语情况下，不用看主句的结构了吗？也就是不管主句里谁做主语，后面都可以用a trend 来修饰？

应该看句子的意思来判断，前面描述的是一种趋势当然说明这个趋势用a trend是可以的。当然你想对前面任何一个词或短语进行解释说明那就要用相关的引导词了。

一看你的解释就明白了，一开始做题就糊涂了，陷入语法困境中

另外感觉A  Women are expected to be the majority of student entering law school this fall和B  The majority of students entering law school this fall are expected to be women是有区别的，但又说不清楚，那位NN帮忙梳理一下，谢谢。

B  The majority of students entering law school this fall are expected to be women, a trend that will ultimately place

突然晕啦...the majoirty的谓语是复数吗?

后边得trend是独立主格吗？如果不是，那么也不是同位语，因为它和majority不是同一类性质的词。trend是做什么成分得？
