so...as的用法

so...as一般用于否定句，so...as一般在句型not so...as中使用，与not as...as同义，也就是说so...as常用于否定句中。

词组so...as 与as...as有什么区别?

1、as...as可以用在肯定句中，表示“像...一样”，后面的形容词或者副词要用原级：

She can run as fast as a deer.她能跑的像鹿一样快。

They work as hard as they do.他们工作像你一样努力

2、在否定句中，as...as和so...as都可以用：

I don't go there as much as I used.我现在到那里不像过去那么多了。

I didn't do as (so)well as I should.我做的不如我应做的那么好。

3、这种句子中也可以有一个表示程度的状语：

I don't speak half as (so) well as you.我讲得不及你一半好。

She can read twice as fast as he does.她的阅读速度比他快一倍。

注意：as后面的形容词如作定语，而被定语修饰的名词有不定冠词a时，不定冠词a须放在形容词之后。

如：German is as difficult A language as English.德语和英语一样难学。

这样的词序也适合于so...as；

如：I have never seen so beautiful A place as Guilin before.我过去从未去过像桂林这样美的地方。
