as… as和so… as的用法有什么区别吗?

如题所述

1)as ...as 表示“相等”之意;用于同级比较时,既可用于肯定中也可用于否定句中;

如:

Mike is AS tall AS I.麦克和我一般高。

Mike is not AS tall As I.麦克没有我高。

2)so … as 只能用于否定句中,也就是说,通常是以 NOT so...as 出现的;

如:

The Atlantic Ocean is NOT AS big AS the Pacific Ocean.大西洋没有太平洋大。

3)在否定句中既可以用 not as ...as...也可以用 not so...as,而在肯定句中只能用 as...as; 

如:

The Atlantic Ocean is NOT AS big AS the Pacific Ocean.大西洋没有太平洋大。

The Atlantic Ocean is NOT So big AS the Pacific Ocean.大西洋没有太平洋大。

You know AS well As I do.你和我一样明白。

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.我过去从未过像桂林这样美德地方。

拓展资料

1、当用于同级比较时,as..as 既可用于肯定中也可用于否定句中,而so..as 只能用于否定句中。

2.当表示只要时,两者没有什么区别,可以替换。

如:Our profits will be good as/so long as the dollar remains strong.

so long as    只要    

如:They are tolerable so long as tomorrow is better.只要明天会更好,这一切就都可以忍受。

as/so long as 的用法

在表示during the whole time that(长达……之久)或while(只要)的含义时,往往用as long as.如:

1、They all continued their regard for me as long as they lived. 他们毕生都在关心着我。

2、As long as there is life there is hope. 留得生命在,不怕没希望。
