现在完成时态:
构成: 主语 + have/has + 过去分词 + 其他。 否定式: 主语 + haven't/hasn't + 过去分词 + 其他。 一般疑问式: Have /Has + 主语 + 过去分词 + 其他 简略答语: Yes, 主语 + have/has.(肯定)

一、现在完成时态用法一: 动作发生在过去,一直延续到现在,可能还会继续。(如图)
●———————————— 现在
该用法中常用词:for, since, how long. 例如:for后跟时间段,since 后跟
过去时间点或者是过去时态的句子。 How long have you learned English? I have learned English for ten years. I have learned English since ten years ago.
注意:此用法中还要注意,因为要表示动作一直延续到现在,所以主句中的动词要选择表延续性的动词。例如:
He has been dead for ten years.(be dead是die的延续性词) He has been away for two hours. (be away是leave的延续性词) 常见瞬间动词与延续动词的转换:
come / go / arrive/ get to/reach -- be in s.p.
leave – be away buy – have die – be dead borrow – keep join sth.– be in sth. come back – be back begin to do sth – do sth ( begin to work – work ) begin - be on become sth. – be sth.
二、现在完成时用法二: 表示过去某个动作发生过,对现在造成影响。(如图) ●…………………………现在
此用法中常用词有:already, yet, just, before, lately, recently, ever/never, so far。 (注意:already, just常用于肯定,yet 常用于疑问和否定,其他词都可以。)例如: He has already come back. He has just come back. He hasn't come back yet. Have you ever read this novel? Have you heard from him recently?
注意: 此用法中的动词多表示瞬间性动词,也有延续性动词出现,但是要正确
理解其含义。例如:
He has died. 他已经去世。 He has been dead. 他去世过。 He has married. 他已婚。 He has been married. 他结过婚。
三、现在完成时态用法三:表示动词重复到现在,可能还会继续。(如图) ● ● ● ● ● ● 现在
此用法中常用词有:数词,次数(once, twice…)。例如: I have made five phone calls today. I have been to Beijing three times. He has read the book twice.
注意: 区别 have been to sp. 和 have gone to sp.
have been to sp. 表示去过某地已回来;have gone to sp. 表示去某地了,还未回。
现在完成进行时态:
构成: 主语+ have/ has + been doing
否定: 主语+ have / has + not + been doing 一般疑问:Have / Has + 主语 + been doing 简略回答: Yes, 主语 + have/ has.
No, 主语 + haven’t/ hasn’t.
(此时态可以换成现在完成时态,相当于现在完成时态中的第一种用法。)
