as引导定语的从句

引导语:关系代词as引导定语从句时,既可以单独使用,也可以其它词连用,其用法要比thatwhich更为复杂,值得注意。现将其归纳如下。

as引导定语从句与其它词连用

A.用于the same...as...结构中

This is the same sickle as I lost yesterday.这把镰刀和我昨天丢的那把一样。

This is the same material as is used in building the bridge.这和建那座桥所用的材料一样。注意:在这一结构中,as有时可以由that代替。例如:

1.当定语从句省略谓语部分时,要用as。例如:

She uses the same scent as youdo)/that you do.她用的香水和你的一样。

This book of his is the same as yours.他的这本书和你的那本一样。

2.在容易引起歧义时,慎用asthat。例如:

This is the same knife as I lost last week.(一般理解为:这把刀和我上周丢的那把相似。也可理解为:这是我上周丢的那把刀。)

This is the same knife that I lost last week.这是我上周丢的那把刀。

3that在现代英语中可作关系副词,而as则不可。例如: I live in the same district that he lives.(不可用as。) B.用于such...as...结构中

C.用于“so+adj.+an)+n.(单数)+as结构中 We witnessed so great a parade as nobody ever dreamt of in preliberation days.我们见到在解放前没有人曾经梦想过的一次盛大的。

Aas单独引导定语从句时,先行词可以是一个词,但更为常见的是:它的先行词是整个主句,有时也可以是一个短语。例如:
