现在完成时1

现在完成时1

初三英语专项复习(一)现在完成时一、现在完成时的定义:(1)(标志词有:、、、、、其中表示否定的有、(置于于句末)。

(2)可以和表示从过去某时刻开始延续到现在的时间状语连用,常用的词有+ 时间;+ 时间(词组/句子);(迄今为止);(从那以后);before. 在这种用法中需要强调的是动词必须是动词。

背过下面短暂性动词转换成延续性动词:(1)用含有相同意义的近(同)义词(组)替换如:borrow→keep;become/come→be;catch a cold/cough/fever→have a cold/cough/fever;get/begin to know→know;go/get to sleep→sleep;buy→have;put on →wear (2)用表示延续状态的系表结构“be+形容词(介词短语/副词/名词)表示,如:arrive in(at)/get to /reach→be in/at;come (to ) →be in/at;fall ill(sick)/asleep→be ill(sick)/asleep;jion→be in the…/be a…member;die→be dead;close→be closed;lose→be lost;go(come) out→be out;leave→be away;get up→be up;open→be open;begin/start→be on;end/finish→be over(3)用句型“It has been/It’s +时间段+since从句”或“时间段+has passed +since从句”注意since 后面的从句用一般过去时。

二、在完成时的句式构成(必须理解、记住)肯定形式:主语+ / +否定行式:主语+ / / +一般疑问形式:/ +主语+ ?三、动词过去分词的变化同于过去式的变化,分规则变化(变化规则:1.直接在后面加—ed:2.以重读闭音节结尾,末尾只有一个辅音字母,要先双写这个字母再加—ed;3.以辅音字母加y结尾的,把y边i,再加—ed.)和不规则变化(课本255—257页,必须背过,可以分类去记忆:1.AAA型;2.AAB型;3.ABB型;4.ABA型;5.ABC型)四、现在完成时与一般过去时的异同相同之处:动作都发生在过去不同之处:(1)一般过去时只强调在过去发生某一个动作;现在完成时强调的是过去发生的动作与现在的关系(对现在的影响或结果;过去发生的动作持续到现在)(2)一般过去时常与具体的过去时间“合作”(yesterday,last week,three days ago,in 1988,just now,when he was young.)。

现在完成时讲解一、基本结构:主语+have/has+过去分词(done)①肯定句:主语+have/has+过去分词+其他②否定句:主语+have/has+not+过去分词+其他③一般疑问句:Have/Has+主语+过去分词+其他④特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他)二、用法1)现在完成时的"完成用法"现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在.He has turned off the light.他已把灯关了。

(动作结束于过去,但说明的是现在的情况--灯现在不亮了。

)I have spent all of my money.(含义是:现在我没有钱花了.)Jane has laid the table.(含义是:现在桌子已经摆好了.)2)现在完成时的"未完成用法"指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去。

这里的动词要用持续性动词。

常与for(+时间段),since(+时间点)连用.Mary has been ill for three days.Mary has been ill since three days ago.注意:1.现在完成时不能单独与准确时间连用,(如表示过去的时间状语)如yesterday(morning、afternoon),last(morning、afternoon)等,除非与for, since连用.2.现在完成时往往同表示不确定的过去时间状语连用,如already(肯定), yet(否定,疑问), just, before, recently, still, latel y等:He has already obtained a scholarship.I haven't seen much of him recently (lately).We have seen that film before.Have they found the missing child yet ?3. 现在完成时常常与表示频度的时间状语连用,如ever, never, twice, several times等:Have you ever been to BeijingI have never heard Bunny say anything against her.I have used this pen only three times. It is still good.George has met that gentleman several times.4. 现在完成时还往往可以同包括现在时间在内的时间状语连用,如up to these few days/weeks/months/years, just, up to present(now), so far等:Peter has written six papers so far.Up to the present everything has been successful.5. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作.We have had four texts this semester.6. have been to 和have gone to的区别have been to 强调“去过”,现已不在那里,如:He has been to the USA three times.他到美国去过三次。

用于肯定句 用于否定句,疑问句
