现在完成时
一、基本形态
表示到现在为止已经完成或刚刚完成的动作,强调结果或对现在的影响。
常跟already, yet, never, ever, just, before, so far(到目前为止), for,since等。
1.肯定句
现在完成时的肯定句式是
“have(has)+过去分词”。
注意:该句式中的have或has是助动词,has用于第三人称单数,其它人称一律用have。
2.疑问句
现在完成时的一般疑问句式是把助动词have或has提到主语之前。 (回答用“Yes,...have(has)./“No,...haven’t(hasn’t).” )
3.否定句:现在完成时的否定句式是
“haven't(hasn't)+过去分词
练习1把下列句子改为否定句和一般疑问句
1. I’ve already had dinner.
I ________ ________ dinner ________.
____________________________________
2. He’s finished his homework.
He ________ ________ his homework.
______________________________________
二、for+表示一段时间的词组(必须跟可持续性动词),since+表示过去某一时刻的词或词组
eg.--- I’ve lived here for 15 years.
eg.--- I’ve lived here since 15 years ago(1997)
延续性动词和短暂性动词的概念
英语中,延续性动词表示能够延续的动作,这种动作可以延续下去或产生持久影响。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
短暂性动词也称非延续性动词,表示不能延续的动作,这种动作发生后立即结束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。
练习2 考点选用for和since填空:
1.We haven’t seen each other ______ a long time.
2.His father has been in the factory ______10 years ago.
3.The film has been on ______ 20 minutes.
4.Mr Green has worked here ______ he came to China.
5.His grandparents have been dead ____several years.
三、分清与一般过去时的用法
现在完成时属于现在时态的范围,不能和表示过去的时间状语连用,如yesterday,last night,three weeks ago,in1990等.而一般过去时只表示过去的动作或状态,和现在不发生关系。
eg--- I have seen the film.
eg--- I saw the film last week.
eg--- He has lived here since 1993.
eg---- He lived here in 1993.
练习3动词填空:
1._____ you ________(clean) the room?
Yes, we__________(do) that already.
When _______ you ______(do) it?
We _______(do) it an hour ago.
2.______ he ______(see) this film yet? Yes.
When _____ he _____(see) it?
注意/考点
1) have gone (to) 与have been(to)
have gone to表示某人已离开了原地,去了另外某地,说话时人还未回来。have been to表示某人曾去过某地, 说话时人已经回来了。
如:He has been to Xi’an twice. 他曾经去过西安两次。(已经回来了)
You can’t find him. He has gone to Xi’an.你找不到他。他去西安了。(没回)
