(3) have gone to和have been to的区另have gone to表示去而未归” have been to表示去已归来”。
现在完成时和过去完成时(1)现在完成时:1.概念:过去发生或已经完成的动作对现在造成的影响或结果,或从过去已经开始,持续到现在的动作或状态。
2.时间状语:(时间标志词)these days,recently, lately,in/during the past few years, already ,yet ,never ,ever, just, before, in the past (last) few days,so far ,once, twice ,for+时间段,since+过去的时间点,since+—般过去时的从句等。

6.反义疑问句:直接用has /have 进行反问7.现在完成时的用法:①表示过去发生或已经完成的动作对现在造成的影响或产生的结果。
如:—Have you had your lunch yet?你吃过午饭了吗?—Yes,I have.I've just had it.是的,我刚吃过。
(现在不饿了)I have closed the door. (门现在是关的)②表示从过去开始一直持续到现在的动作或状态,可能还要持续下去,常与for 或since 连用。
表示持续的动作或状态多为延续性动词。
如:He has lived here since l999.自从1999 年以来,他就住在这儿。
I have learnt English for ten years.我学习英语有10 年了。
We have lived here for two years. (过去住到现在)8. 难点:(1)现在完成时可和疑问词where, why, how 连用,但不能和when 连用.故现在完成时对时间的提问不用when,只用how long。
Where have you been? Why have you turned off the radio? When have you come back? (×)He has been in China for 4 years. (提问) When(×) / How long(✓) has he been in China?(2)have been to /have gone to /have been in 的区别have been to +地点表示曾经去过某地,现人已返回。
(once ,twice ….)have gone to +地点表示人已去了某地,人还未返回。
(where is sb ?)have been in +地点表示在某地呆多长时间。
(for…../ since …..)I have been to Beijing twice.–Where is Tom? –He has gone to HK.Lucy has been in this school for two years.(3)短暂性动词和持续性动词的现在完成时A.若后面没有时间状语“for + 时间段,since +时间点”时,短暂性和持续性动词都可用于现在完成时。
如:I have bought(短暂) a new computer. (✓)He has already lived (持续) in the small village. (✓)B.若后面有时间状语“for + 时间段,since + 时间点”时,要用持续性动词或短暂性动词的否定。
如:They have stayed (持续) in the village for 10 years.I have taught(持续) English at this school since 5 years ago.You haven’t received (短暂)her letter for 2 weeks.We haven’t left (短暂)China since 20 years ago.注意:非延续性动词的否定形式可以与表示延续时间的状语连用。
即动作不发生的状态是可以持续的。
(错)I have received his letter for a month. (对)I haven't received his letter for almost a month.C.短暂性动词的肯定不能与“for + 时间段,since + 时间点”连用,若要和他们连用则要将短暂性动词变为相对应的动词。
如:I have come here for 3 years. (×)→I have been here for 3 years.( ✓)现举例说明这类动词的变化:下划线的词是错的,括号里的词是对的,borrow / lend→ kept She has borrowed(kept) the magazine since two weeks ago.catch→ had Kate has caught (had) a cold for one day.buy→ had I’ve bought (had) this radio for 3 years.put on → worn He has put on (worn) the new coat for a week.leave / go→been away They have left(been away) for one year.start / begin→ been on The film has begun (been on) for 8 minutes.get up→ been up He has gone up(been up) more than two hours.move→ been out (of) Jim’s family have moved(been out of) here for over 2 years.finish→ been over The football match has finished(been over) for two hours.open→ been open The factory has opened(been open) since 1990.close→ been closed The factory has closed (been closed) for 2 months.die→ been dead That old man has died(been dead) for three years.j oin→ been in/ been a member (of) Her father has joined (been in) the Party for ten years.come/ become/ arrive→been(in)They have come to(been in) this school since 1990.注意:非延续性(短暂性)动词的肯定不能与表示一段时间的状语连用。
必须把非延续性动词改为相应的表示延续性的动词或短语,这时可与表示一段时间的状语连用。
常见的非延续性动词通常作如下变换:come/go to → be at /in ,leave→be away from,buy→have,borrow/lend→keep,die→be dead,start/begin→be on,close→be closed,open→be open,join→be in/be a member of/be a soldier. ... ,go/come there→be there,get married→be married,get up ---be up,catch a cold→have a cold,return→be back,fall ill→be ill,become→be,has gone to→has been in,die---dead ,make friend -- be friendfall asleep ---be asleep ,catch a cold – have a cold,reach/get/arrive---stay/be 等。
误:l have bought this computer for two years. 正:I have had this computer for two years.这台电脑我买了有两年了。
(4)与现在完成时有关的四种句型之间的转换。
现在完成时的四种句型:A).主语+短暂性动词的过去式+ 时间+agoB).主语+have/has +延续性动词的过去分词+for…./since …. ago.C).It’s +时间段+si nce +短暂性动词的过去式D).时间段+has passed +since +短暂性动词的过去式如:“我来广东有 4 年了”可用以下句型表示:I came to Guangdong 4 years ago. →I have been in Guangdong for 4 years.It’s 4 years since I came to Guangdong →Four years has passed since I came to Guangdong.His grandfather died two years ago. His grandfather has for two years.two years his grandfather .Two years his grandfather .(5)现在完成时与一般过去时的区别①. 标志词不同(具体看两种时态标志词) 如:I went to cinema two days ago. (一般过去时标志词).He has been away since ten days ago. (现在完成时的标志词)②. 一般过去时表示动作发生在过去,与现在无关。
而现在完成时表示动作发生在过去,对现在造成影响。
I saw the film yesterday. (我昨天看了这部电影)(强调看的动作发生过了)I have seen the film before.(过去看过电影,强调对现在的影响,电影的内容已经知道了,不想再看了)I won’t see it again.Has he returned the library book? Yes, he has.When he (return) it ?He (return)it yesterday afternoon .※句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。
