现在完成时的时间状语
现在完成时属于现在时范围,故不能和过去的时间状语连用。如:yesterday、last Sunday、in1990、three years ago等。但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。
1、用副词already和yet。already一般用于肯定句中,yet一般用于否定句和 疑问句中。
如:We have already finished our homework.
我们已完成作业了。
2、用ever 和never。多用于否定或疑问句中,表示“曾经”或“从未“等。
如:-Have you ever been to the Great Wall?
你曾经去过长城吗?
3、用表示到说话为止的过去时间状语,如just,before,up to now,the past few years等。
例如:I have seen her before,but I can not remember where.
我以前见过她,但记不起在哪里见过。
4、用包括“现在”在内的时间状语,如:now,today,this morning(month,year,term)等。
例如:-Have you met him today?-No,I haven't.
今天你见过他吗?我没有。
