助动词
表示过去发生或已经完成的动作对现在造成的影响或结果。强调的是现在的情况,现在完成时可already,yet,just,before ,never, ever,连用。
本单元主要学习现在完成时的第一个用法。
I have just cleaned my clothes.(“洗衣服”是发生在过去的动作,对现在造成的结果是“衣服干净了”)
I have seen her before, but I can not remember her name..我以前见过她,但我不记得她的名字了
We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。
---Have you ever been to the Great Wall 你曾经去过长城吗
---I have never been to the Great Wall.我从未去过长城。
现在完成时跨在两个时间之上,一是过去,一是现在。
它的作发生在过去,但对现在有影响(或结果),
而这种影响(或结果)却往往是说话人的兴趣所在,所以常常后面不用时间状语。
(1) The car has arrived. 车子来了。(结果:车子已在门口)
(2) Someone has broken the window 有人把窗户打破了。(结果:窗户仍破着)
(3)I have lost my pen. 我把钢笔丢了。(结果:我现在无钢笔用)
(4) He's been ill.他刚生过病。(结果:现在脸色还不好)
注意现在完成时常常后面不用时间状语。
这些句子都没有时间状语
现完完成时和一般过去时的区别。
现在完成时把过去的动作和现在的结果联系起来,
一般过去时只限于表示过去的动作本身,与现在的结果无关。
1.I have cleaned my room. 我已经打扫过我的房间了,(过去打扫了房间,对现在造成的影响就是房间干净了,不用再打扫了)。
2.I cleaned my room last week. 我上周打扫了我的房间.(只说上周打扫了房间这个动作本身,和现在一点关系都没有,也许现在的房间已经脏了)
3.My father has gone to Shanghai. 爸爸已经去上海了。(爸爸过去去了上海,对现在造成的影响就是他现在不在本地了,他现在在去上海的路上或就在上海了)。
4.They have bought a dictionary. 他们买了一本字典.(他们过去买了一本字典,对现在造成的影响就是他们现在有一本儿字典了,不用再买了)。
