现在完成时用法小结一、现在完成时的构成:助动词have(has)+ 过去分词否定式have(has)not+ 过去分词疑问式:have\has not+主语+过去分词;have\has +主+not+过去分词二、现在完成时态的用法1、表示开始于过去的动作一直持续到现在,而且还可能继续持续下去。

这时,谓语动词一般为延续性动词。

例如:I have been a teacher for 5 years\since 5 years ago.(五年前是个时间点。

一直持续到现在的的状态,一直在做老师,以后还是老师。

)They have lived here for 7 years.(第一层含义,到说话这一刻,一直住在这里,这是一个持续状态。

第二层含义,如果他们正在搬家时候说这句话,则说明live这一事实不再持续,到此为止,他们可能要搬去别处住。

)◆这一用法的特点:谓语动词为延续性动词;动作发生在过去,持续到现在,并有可能继续下去;和“一段时间”的状语连用。

●since+时间段:I have worked in this place since 1990.I have lived in Xi’an since I left school\since 5 years ago●for+ 时间点: I have worked in this place for 20 years.I have lived in Xi’an for 5 years ago.“到目前为止…”:until now, ,up to\ till\until now,so farUntil now,I have been a monitor for 3 years.(放在句末亦可)Our country has until now, ,up to\ till\until now,so farWon 20 golden medals.●“在最近几个世纪、年、月以来……”in \over \during the past few years,for the lastfew century,through centuries,throughout the past decades.For the last few decades, great changes have taken place in Beijing.2.表示过去某时发生或完成的某一动作,谓语动词是短暂性动词(对现在造成的影响或结果)。
