as long as和so long as引导条件状语从句的区别

作者: admin来源: 网络文章 时间: 2016-06-26

as long as 和 so long as 均可表示“只要”,用于引导条件状语从句,两者没什么区别。如:

I don't care so [as] long as she lets me be with her son. 只要她让我和她儿子在一起,我不在乎。

You can take my car as [so] long as you drive carefully. 你可以用我的汽车,只要你小心点儿开。

You may use my dictionary as [so] long as you don't keep it too long. 只要使用时间不太长,你可以用我的词典。

但是,当 as long as 用于本义表示“与……一样长”时,与 so long as 在用法上是有区别的,即 as long as 可用于肯定句或否定句,而 so long as 只用于否定句,不用于肯定句。如:

It took three times as long as I had expected. 这件事比我预料的多花了两倍的时间。

It didn't take as [so] long as I expected. 花的时间比我预料的短。
