[求助]请教菜鸟问题

187. In one of the bloodiest battles of the Civil War, fought at Sharpsburg, Maryland, on September 17, 1862, four times as many Americans were killed as would later be killed on the beaches of Normandy during D-Day.

(A)  Americans were killed as

(B)  Americans were killed than

(C)  Americans were killed than those who

(D)  more Americans were killed as there

(E)   more Americans were killed as those who

Choice A, the best answer, is the only option that accurately expresses the comparison by using the idiomatic form as many... as. In B and C, as many ... than is unidiomatic, and in C and E, those who is a wordy intrusion. In D and E, more is redundant because the phrase four times as many in the original sentence conveys the idea of more.

菜鸟问题：

1  从句would later be killed on the beaches of Normandy during D-Day.

2  those who是否=that？

3 在 一个句子中，使用；和，都有哪些不同

多谢。

1. 这里 as 前后的比较对象一致，所以才省略的。

2. those who <>ｔｈａｔ

３．　＂；＂　表示其后面是完整句子，　“，”表示其后面不是完整的句子，句子还没结束呢。

谢谢joe11

再请教一个菜鸟问题，我觉得好象有些从句里面的WHICH IS/ARE，THOSE WHO可以省略掉，请问是在哪些从句里面可以省略掉呢？麻烦了，谢谢拉！

"再请教一个菜鸟问题，我记得好象有些从句which is/are+过去分词, those who+be动词中which is/are, those who可以省略，请问是在哪些情况可以省，哪些情况下不可以省呢？"

OG-2 对 A 的解释：Choice A is also wordy, since that is can be deleted without loss of clarity.

2. Since 1981, when the farm depression began, the number of acres overseen by professional farm-management companies have grown from 48 million to nearly 59 million, an area that is about Colorado's size.

(A)  have grown from 48 million to nearly 59 million, an area that is about Colorado's size

(B)   have grown from 48 million to nearly 59 million, about the size of Colorado

(C)  has grown from 48 million to nearly 59 million, an area about the size of Colorado

(D)  has grown from 48 million up to nearly 59 million, an area about the size of Colorado's

(E)   has grown from 48 million up to nearly 59 million, about Colorado's size

由此可见，省略后不会产生理解歧义的可以省略。

“再请教一个菜鸟问题，我觉得好象有些从句里面的WHICH IS/ARE，THOSE WHO可以省略掉，请问是在哪些从句里面可以省略掉呢？”

我头大了，好像没有具体的规则，一般而言，引导非限制性定语从句的which是不能省略的。

Those 做主语时也是不能省略的，who 是修饰those（指人）也是不常省略的。

还是就题论题吧。

请大家继续畅所欲言。

谢谢JOE斑竹的回答，我会慢慢体会一下。

祝大家新年快乐！
