高考临近,小编为大家准备了些高考词汇的辨别,希望大家能从中获益!
■before long 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。
■long before
(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。
■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。
