高考英语易错词汇解析:before long与long before

1. before long 的意断是“不久,很快”。如:

I‘ll be back before long. 不久我就回来。

Before long he got married. 不久他就结婚了。

2. long before有两个用法:

(1) 老早,早就(单独使用,表示比过去某时早得多的时间)。如:

She had left long before. 她老早就离开了。

That had happened long before. 那事老早就发生了。

注:long ago 表示“很久以前”,指的.是从现在算起的很久以前,通常与一般过去时连用:

I met him long ago. 我很久以前就认识他了。

(2) 在……的很久以前,在还没有……的很久以前。如:

She had left long before his return [he returned]. 在他回来的很久以前她就走了。

He had worked in the factory long before he got married. 在他还没有结婚的很久以前他就在这家工厂工作了。

注:此时的主句谓语通常用过去完成时,但有时也可用一般过去时(因为 before 已体现了动作的先后关系)。如:

This happened long before you were born. 这事在你还没出生以前很久就发生了。

另外注意以下句式:

It is [was, will be] long before……在……前需要很久。如:

It was long before he came back. 过了好久他才回来。

It won‘t be long before we see each other. 不久我们又会见面的。

比较:

It wasn‘t long before he realized his mistake. / Before long he realized his mistake. 不久他意识到了自己的错误。
