1. 现在完成时常常与表示频度的时间状语连用,
如often, sometimes, ever, never, twice, on several occasion等:
I have used this pen only three times. It is still good.
George has met that gentleman on several occasions.Have you ever been to Beijing
I have never heard Bunny say anything against her. 2.现在完成时不能单独与准确时间连用,
如yesterday(morning、afternoon),last(morning、afternoon)等,除非与for,since连用. 3. 现在完成时还往往可以同包括现在时间在内的时间状语连用,
如now, up to these few days/weeks/months/years, this morning/week/month/year, just, today, up to present, so far等:
There has been too much rain in San Francisco this year.
The friendly relations and cooperation between our two countries have been enhanced in the past few years.
Up to the present everything has been successful.Peter has written six papers so far.
Man has now learned to release energy from the nucleus of the atom. 3.现在完成时往往同表示不确定的过去时间状语连用
如already, yet, just, before, recently,still, lately等:
We have seen that film before.
Have they found the missing child yet ?He has already obtained a scholarship.
I haven't seen much of him recently (lately). 4. 现在完成时表示现在之前业已完成的动作,虽然其效果或影响仍然存在但已不再继续,
但是有一些现在完成时的句子,在后面加上for+一段时间,则现在完成时的动作就表示延续性.
Thomas has studied Russian. (现在不再学俄语)
Thomas has studied Russian for three years. (=Thomas began to study Russian three years ago, and is still studying it now.(同第2点用法第一个例句)
5. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作. We have had four texts this semester.
