初中英语被动语态的教案(教学设计)

1、初二英语被动语态一、语态概述英语的语态是通过动词形式的变化表现出来的.英语中有两种语态：主动语态和被动语态.主动语态表示主语是动作的执行者.巧记为：主动、主动、主去动.例如：ManypeoplespeakEnglish.谓语：speak的动作是由主语manypeople来执行的.被动语态表示主语是动作的承受者,即行为动作的对象.巧记为：被动、被动、主被动.例如：Englishisspokenbymanypeople.主语English是动词speak的承受者.判断：看我上面举的例子,你来判断哪个是主动哪个是被动？Heopenedthedoor.他开了门.主动句Thedoorwasopened.

2、门被开了.被动句说明：好了,现在我们对被动语态的句子形式有了一个形象的熟悉,但英语句子是千变万化的,这时就需要你有火眼金睛了.下面老师就来具体讲一讲被动语态的构成.二、被动语态的构成被动语态由助动词be+及物动词的过去分词构成.人称、数和时态的变化是通过be的变化表现出来的.现以teach为例说明被动语态在各种时态中的构成.说明：别看英语中一会儿主动被动一会儿现在时一会儿过去时啥的,好似看得咱们眼花缭乱啦.其实呢,这么一堆东西归纳起来,就两点：时态和语态.一般现在时：am/is/are+taught一般过去时：was/were+taught一般将来时：will/shallbe+taught现在

3、进行时：am/is/arebeing+taught过去进行时：have/hasbeen+taught现在完成时：have/hasbeen+taught歌诀是：被动语态be字变,过去分词跟后面.说明：那么,什么时候用被动语态呢？简单的说,但凡汉语中带被的句子,都能转换成英语的被动语态.三、被动语态的用法1不知道或没有必要说明动作的执行者是谁.例如：Somenewcomputerswerestolenlastnight.一些新电脑在昨晚被盗了.不知道电脑是谁偷的Thisbookwaspublishedin1981.这本书出版于1981年.2强调动作的承受者,而不强调动作的执行者.例如：thewin

4、dowwasbrokenbyMike.窗户是迈克打破的.Thisbookwaswrittenbyhim.这本书是他写的.Eighthoursperdayforsleepmustbeguaranteed.每天8小时睡眠必须得至U保证.歌诀：谁做的动作不知道,说出谁做的没有必要；动作承受者需强调,被动语态运用到.主动态和被动态指的是动词形式,是词法概念；而主动句和被动句那么指的是句子结构,从而是句法概念.所谓主动句就是由主动态动词词组作谓语动词的句子,而被动句那么是由被动态动词词组作谓语动词的句子.补充内容：四、主动语态变被动语态的方法(1)把主动语态的宾语变为被动语态的主语.(2)把谓语变成被动

5、结构(be+过去分词)(根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式).(3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格.例如：Allthepeoplelaughedathim.Hewaslaughedatbyallpeople.Theymakethebikesinthefactory.Thebikesaremadebytheminthefactory.歌诀是：宾变主,主变宾,by短语后面跟.谓语动词变被动,be后过分来使用.五、含有情态动词的被动语态含有情态动词的主动句变成被动句时,由情态动词+be+过去分词构成,原来带to的情态动词变成

6、被动语态后“to仍要保存.歌诀是：情态动词变动,情态加be加过分,原来带to要保存.例如：Wecanrepairthiswatchintwodays.Thiswatchcanberepairedintwodays.Yououghttotakeitaway.Itoughttobetakenaway.Theyshoulddoitatonce.Itshouldbedoneatonce.1ThePeople'sRepublicofChina_onOctober1,1949.A.foundB.wasfoundedC.isfoundedD.wasfound2 EnglishinCanada.A.s
