现在完成时和过去完成时
现在完成时由“have/has+过去分词”构成,主要有两个含义:
①表示过去发生的动作对现在造成的影响和结果,常用的时间状语有many times,just,yet,ever,never,just,already,so far, by now等。
I have already watched the TV play. 我已经看过这部电视剧了。(现在我对它不感兴趣了)
——Have you found your lost pen yet?
——No, I haven’t found it yet.(我很着急)
②表示动作或者状态在过去已经开始,持续到现在,也许还将持续下去。用于延续性动词,常常与so far、for或者since短语连用。since + 时间点 /从句,for + 时间段,如for two months等。
