中考英语 现在完成时 专题复习课件
展开1、结构:主语+have/ has +过去分词(dne) 【注:当主语是第三人称用has,其余人称用have】
(以下示例以wrk为例子)
1、表示过去发生的动作对现在造成影响。e.g: I have finished my lunch. S, I am full nw.2、表示动作或状态从过去某时开始,一直延续至今。(可能刚结束,也可能继续下去)e.g: I have lived here fr 8 years.
since和fr是现在完成时当中常见的标志词。since“自从……”,fr“持续了……”。since用来说明动作的开始时间,fr用来说明动作延续的时间长度。
1、since的用法:① since加过去一个具体的时间点(具体的年/月/日,或钟点)since 1990、since yesterday、since 5 ’clcke.g: He has lived here since 1990. ② since+时间段+age.g: She has been a teacher since tw years ag.③ since+一般过去时的从句e.g: I have wrked here since I mved here.④ 固定句式:It is/ It has been+时间段+since+一般过去时的从句e.g:It is/ It has been five years since I came here.
2、fr的用法:① fr+时间段:e.g: He has lived here fr 8 years.3、since和fr的句式转换:since+时间段+ag=fr+时间段e.g: They haven't changed since twenty years ag. =They haven't changed fr twenty years.
4、用hw lng 对since和fr引导的时间状语进行提问:e.g:- Hw lng have yu lived here? -I have lived here fr 4 years./ I have lived here since 2020.【拓展知识】① hw lng:多久,提问时间段,常用于现在完成时② hw far:多远,提问距离 e.g: Hw far is it frm here t the airprt? ---10 kilmeters.③ hw sn:多久以后,提问将来的时间,答语常用in+一段时间 e.g: Hw sn can yu arrive? ---In 5 minutes. ④ hw ld:多大,提问年龄

4、延续性动词与短暂性动词
延续性动词表示能够延续的动作:wrk、live、sleep短暂性动词表示不能延续的动作,这种动作发生后立即结束:pen、begin、marry1、用法:① 若现在完成时的句子中,含表示时间段的时间状语(如含since/fr引导的时间状语),则谓语只能用延续性动词。e.g: Mr. Smith has learned Chinese fr tw years. ②【拓展】在否定结构中,短暂性动词可以与since和fr引导的时间状语连用。e.g: I haven’t received his letter fr a lng time.
2、延续性动词与非延续性动词的转换:短暂性动词不能和表示一段时间的时间状语连用,需要进行转化。① 短暂性动词→延续性动词:buy 买→have 有 brrw 借→keep 保留 put n 穿上→wear 穿着 cme/g/becme 来/去/变成→be 在/是e.g: I have brrwed this bk fr 5 days. I have kept this bk fr 5 days.② 短暂性动词→be+名词:jin 参加→ be a member f 成为…的成员 g t schl去上学→be a student成为一名学生e.g: I have jined the army since last year. I have been a member f the army since last year.
③ 短暂性动词→be+形容词:die 死亡→be dead 死了finish 结束→be ver 结束begin 开始→be n 在上映/已开始leave 离开→be away 远离的fall asleep 入睡→be asleep 睡着的marry 结婚→be married 已婚e.g: The mvie has begun fr 5 minutes. The mvie has been n fr 5 minutes.④ 短暂性动词→be+介词短语:g t schl去上学→be in schl在上学 jin the army参军→be in the army在军队中 e.g: They have cme t Beijing fr 5 years. They have been in Beijing fr 5 years.
1、have been t / have gne t / have been in的区别:
【注意】当have been t后面接副词,如here, there, hme时,t要省略:e.g:Yu said that Hangzhu is very beautiful. Have yu been there?

2、already、yet、just、never、ever用法区别:用在现在完成时中,强调动作的完成,不强调动作的持续。
1. —Has yur sister finished reading ? —Yes. She has finished it.A. yet; yet B. yet; already C. already; yet2.—Have yu finished yur reprt ________? —Yes, I have ________ finished it.A.yet; yetB.already; alreadyC.already; yetD.yet; already
6、现在完成时与一般过去时
1、两者的区别:现在完成时强调过去发生的事情和现在有关或者持续到现在,对现在有影响。一般过去时仅表示动作发生在过去,与现在无关。e.g: I have already bught this bk, s I dn’t need t g t the bkstre. I bught this bk yesterday.2、【拓展】两者之间的互换:由延续性动词构成的现在完成时的句子,可与短暂性动词构成的句子相互转换。e.g: I have kept the bk fr five days. =I brrwed the bk five days ag.
