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。

GWD-12-Q31:

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.

1. 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


2. Dickinson were written over a period that begins a few years before Susan’s marriage to Emily’s brother and ended shortly before Emily’s death in 1886, outnumber


3. Dickinson, written over a period beginning a few years before Susan’s marriage to Emily’s brother and that ends shortly before Emily’s death in 1886and outnumbering


4. Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother, ending shortly before Emily’s death in 1886, and outnumbering


5. Dickinson, which 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, outnumber

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

本题答案是B。此处which好像修饰的也是前面一个句子噢。

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.

A.    the largest share for any country to contribute

B.    the largest share that any country has contributed

C.    which makes it the largest share for any country to contribute

D.   having the largest share to be contributed by any country

E.    having the largest share to have been contributed by any country

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？

怎么没有人理我呢？自己顶一下

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。
