since后通常接一般过去时。例如,He’s put on a lot of weight since he gave up smoking.
since前后时态
一、since通常通常搭配的时态
当since表示“自从”时,不管它是用作介词、连词还是副词,它通常都要与现在完成时(since前)连用。如:
I’ve worn glasses since my childhood. 我从小就戴眼镜。
The works have been closed since January. 一月份以来这些厂就关闭了。
He’s put on a lot of weight since he gave up smoking. 他戒烟后体重增加了许多。
Nothing has happened since. 从那以后未发生什么事。
She moved to London last May and has since got a job on a newspaper. 她去年五月到伦敦 此后一直在报社工作。
有时连用现在完成进行时。如:
He has been working since noon. 他从中午就开始工作了。
二、since搭配时态的特殊情况
虽然since通常要与现在完成时连用,但在以下情况,它也可以连用除完成时态以外的其他时态:
1. 当主句表示“多长时间”时,动词可用一般现在时(当然也可用现在完成时)。如:
It’s a long time since I met you last. 好久不见了。
It’s just a week since we arrived here. 我们到这里才一个星期。
It’s a long time since I met you last. 从上次见到你,已有很长时间了。
以上各句的it is也可换成 it has been,不过在口语或非正式文体中,用一般现在时的情形比较普遍。
2. 当主句谓语动词为seem等连系动词时。如:
It seems like years since we last met. 我们似乎几年未见面了。
It seems like years since I last saw you. 从上次见到你以来好像已经有许多年了。
3. 当主句和从句表示情况“变化”时。如:
She doesn’t come round to see us so much since her marriage. 自从结了婚,她不怎么过来看我们了。(原来经常来,结婚后就不怎么来了)
