文档介绍：英语语法as和which 作关系代词时的区别
一、as, which 指代整个句子或短语。
由as, which 引导的非限定性定语从句,相当于and this或and that。在很多时候,表示说话人对话语的看法或态度,此时它们的先行词并不是具体的某个词,而是整个句子或短语:
The Chinese government has decided to develop the west of China, which, I dare say, will benefit the people there, especially those who are still leading a poor life. 中国政府决定开发西部,我敢说,这将造福于西部的人民,特别是那些至今过着贫穷生活的人。
She has married again,which delighted ,这使我们很高兴。
John said he’d been working in the office for an hour,which was result of the experiment was very good, which we hadn’t said the work would be done by October,which personally I doubt very much.
二、as, which 用在句末的时候,有些情况下可以互换使用。
He was late for school,as/which was usual with ,这是家常便饭。
He was a foreigner,as/which I knew from his ,我从他的口音中得知这一点。
I live a long way from work,as/which you ,你是知道这一点的。
The author was brought up in a small village, as/which is recounted in some of his stories. 作者是在一个小村庄里长大的,这个问题在他的一些小说了就被提到过。
但是,当主句是否定句时,只能as。例如:
Spiders are not insects, as many people think. 蜘蛛不是昆虫,而许多人却认为蜘蛛是昆虫。
三、as 的特殊用法。
1、如果要说明两者有相似之处时通常用as,表达“正如(情形或事实所表示)的那样、像……的一样”的意思。例如:
She is a fine singer,as her mother used to ,和她母亲当年一样。
She is the same age as you (are). 她和你年龄一样大。[与same...as 连用]
I hope to get such a dictionary as he is using. 我希望有一本和你正在用的一样的词典。[与such...as连用]
As water is to fish,
