急！马上要考试了，还不知道which的用法！贴上几个which的例句，麻烦牛牛们帮忙看看 - ChaseDream

请教各位牛牛，which到底什么时候用是对的？什么时候是错的？最近在做gwd，lzm，og，发现题做得越多越糊涂，原来很坚信看到which 就错，现在发现实在不能肯定，which一会对，一会错，og上面的解释也糊里糊涂。上次大家帮忙解释了，这次我做GWD题时遇到几例，感觉which都在修饰前面的句子，但结果是正确答案。请大家帮忙看看。

Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.

本题答案是E。这里A为什么错？此处的which不是指代一个句子么？

GWD-8-Q20:

Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also caused erosion and very quickly deforested whole regions.

A. Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also

B. Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast), which gave consumers relatively inexpensive houses and furniture, but also

C. The systematic clearing of forests in the United States, creating farmland (especially in the Northeast) and giving consumers relatively inexpensive houses and furniture, but also

D. The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also

E. The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture, but it

GWD-8-Q24:

A March 2000 Census Bureau survey showed that Mexico accounted for more than a quarter of all foreign-born residents of the United States, the largest share for any country to contribute since 1890, when about 30 percent of the country’s foreign-born population was from Germany.

大家的解释为：A，表达方式有歧义，似乎for country是修饰share的（？）

B is the best C，which修饰对象不清，修饰了整个句子。这里的which就错了，感觉和前面的用法差不多？

我觉得which一般错都是因为就近指代的问题。不能太绝对的看到which 就错吧，还是要看具体句子的。

OG253是一个不错的例子。正确选项是由which引导的非限定性谓语从句，错误选项是由于which就进指代。

谢谢几位热心的讲解，尤其是5楼mm还给我找到og的例子，7楼mm找到链接，马上去看。

麻烦大家帮我看看噢，我的帖子好像沉得很下了，自己顶顶上来

sometimes, there is a "," in front of, and avoid to use "which" is to avoid refering to the noun in front of it. "which" refers to mood swings

In his research paper, Dr. Frosh, medical director of the Payne Whitney Clinic, distinguishes mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis.

(C) between mood swings, which may be violent without being grounded in mental disease, and genuine manic-depressive psychosis

OG 49, The cameras of the Voyager II spacecraft detected six small, previously unseen moons circling Uranus, which doubles to twelve the number of satellites now known as orbiting the distant planet.

I didnt use the GWD examples you provided because i haven't started those sections yet. Hope these two examples can help you ~

对GWD-12-Q31,which 用来说明Emily Dickson’s letters to Susan Huntington Dickinson，它指带的其实是LETTER

The systermatic clearing of forests in the united states not only create farmland,是farmland gave consumers relatively inexpensive houses and furniture.

第三题：为什么要用which呢？the largest share for any country to contribute since 1980，已经是一个很好的插入语去说明情况

但第一题为什么which是指代letters呢？不是which一定是就近指代的么？

在图书馆学习一天回到家，发现有这么多热心的解释，真是happy。我看了12楼的解释，理解了。就是对第一题还是有所不解，不过ETS的语法好像是特别活，没有特别统一的规则。不好意思，再贴一题，是今天做GWD24时遇到的，第8题

The results of the company’s cost-cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.

(A) which increased five percent during the first three months of this year after it fell

(B) which had increased five percent during the first three months of this year after it had fallen

(D) with a five percent increase during the first three months of this year after falling

(E) with a five percent increase during the first three months of this year after having fallen

答案是C，我觉得D 也没有什么不对吖？这个which和with短语我老是分不清，麻烦牛牛帮忙解释一下区别。

Emily Dickinson’s letters to Susan Huntington Dickinson, whichwere written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbers her letters to anyone else.

Emily Dickinson 写给SHD的信比她写给任何人的信都多。这些信是在....一段时间内写的.which修饰的是letter.

对于你新提的问题，我觉得which 修饰的是profile,然后它最后用的是over the last two years,所以在which 里面应该用have increased......用with的话就是一个介词短语，介词短语的修饰作用和which是不一样的。具体的你可以用cd的搜索功能搜索一下。

以下是引用Solaris在2005-10-11 23:09:00的发言：

The results of the company’s cost-cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.

(A) which increased five percent during the first three months of this year after it fell

(B) which had increased five percent during the first three months of this year after it had fallen

(D) with a five percent increase during the first three months of this year after falling

(E) with a five percent increase during the first three months of this year after having fallen

答案是C，我觉得D 也没有什么不对吖？这个which和with短语我老是分不清，麻烦牛牛帮忙解释一下区别。

BTW，楼上gg提供的链接我一定仔细研读，不过巨长的帖子噢

關係子句跟介詞短語最大的差別就是後者可以當副詞使用修飾前面的動詞

很多選項看起來都一樣的時候,小心with介片它是不是在這句子裡頭修飾別的東西
