四、合作探究 现在完成时（一）
I．用法：现在完成时表示过去发生的动作对现在造成的影响或结果。常与下列时间状语连
用：just , already, yet, ever, never, before, several times。 现在完成时不能和
表示过去的时间（如：yesterday, last, year, in 1976, two days ago, just now, wh
en she came in 等）连用。

（1）现在完成时表示过去发生的动作对现在的影响。
I have studied English. 表示I know a little English.
He has already come back. 表示He is here now.
常与already, yet, just, recently, ever, never, before等表示不确定时间的时间状
语连用。

（2）现在完成时表示从过去一直持续到现在的动作或状态。She has been ill for 3 days. He has worked in the bank since 1990.
此时，句中谓语动词通常是延续性动词，且常与表示一段时间的时间状语连用。如：these
days, all this year, recently, for ＋时间段以及since＋时间点等等。
II. 构成：have / has ＋动词过去分词
（1）has用于主语是第三人称单数，have用于其它人称。
（2）动词的过去分词构成分为规则动词和不规则动词。规则动词在词尾加ed，其规则与过去
式一样。
不规则动词要记住。例如：take－taken, go－gone等。
III.区分 have/has been to 与have/has gone to
have /has been to 和 have/has gone to 都是指已经去了某个地方，但是 have /has
been to 强调的是曾经去了某个地方并回来了； have/has gone to强调的是去了某个
地方还没有回来。
--Have you ever been to Shanghai? --Yes, several times.
-- Where is Mr. Wang?？-- He has gone to Shanghai.
