现在完成时的构成、用法、标志词、例句、练习

现在完成时态 详细讲解及其练习

一、现在完成时由“have/has+过去分词”构成,主要有两个含义:

①表示过去发生的动作对现在造成的影响和结果,常用的时间状语有many times,just,yet,ever,never,just,already,so far, by now等。

I have already watched the TV play. 我已经看过这部电视剧了。(现在我对它不感兴趣了) ——Have you found your lost pen yet?

——No, I haven’t found it yet.(我很着急)

②表示动作或者状态在过去已经开始,持续到现在,也许还将持续下去。用于延续性动词,常常与so far、for或者since短语连用。since + 时间点 /从句,for + 时间段,如for two months等。

二、现在完成时态和一般过去时态的区别

1)现在完成时和一般过去时都能表示过去发生过的动作,但现在完成时表示过去动作对现在的影响,并且表示这一动作已完成或还可能继续下去;

2)而一般过去时与现在的情况没有联系,仅表示过去的动作,且这一动作到说话时已终止。因此现在完

现在完成时教学设计

备课人:黄红兵

预习导航:

主语+ have/ has + 过去分词(pp)

否定形式haven’t ( have not )+过去分词

hasn’t ( has not ) +过去分词

疑问句把助动词have / has 放在句首

现在完成时的结构

注:主语若是第三人称单数助动词用has

1、规则变化(过去分词与过去时变化规则一样)

(1)、一般动词,在词尾直接加“ed”。

work---worked---worked

visit---visited---visited

(2)、以“e ”结尾的动词,只在词尾加“d ”。

live---lived

(3)、以“辅音字母+ y ”结尾的动词,将“y”变为“i”,再加“ed ”.

study--studied--studied cry--cried-cried

(4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ed ”。 stop--stopped--stopped drop--dropped--dropped

现在完成时的被动语态

have been done是现在完成时的被动语态结构。

现在完成时被动语态用法是高考的重要考点,学习时候应该注意下列几点: 一、掌握现在完成时被动语态的构成

现在完成时被动语态的结构为has/ have been done, 使用has been done时主语为单数,使用have been done时主语为复数。如:

This book has been translated into many languages. 这本书已被译为多国语言。 His bikes have been sold out. 他的自行车已都卖完了。 二、理解现在完成时被动语态的概念

现在完成时被动语态强调一个发生在过去的被动性动作,它有两层意思: 1) 动作已经完成,强调对现在造成的影响或结果: 2)主语与谓语动词之间为被动关系。如:

Our classroom has been cleaned, you needn't clean it now. 我们的教室已经被打扫过,你现在没必要再打扫了。

These flowers have been watered, you can go home. 这些花已经被浇水了,你可以回家了。
