被动语态复习教案

东岔中心学校 刘军翠

教学内容：Review the Passive Voice 教学目标：1.复习巩固被动语态用法及主动与被动之间的转换。

2.各种时态的被动语态构成。

3.被动语态中的特殊情况。

教学重点：被动语态各种时态的结构

教学难点：被动语态各种时态的确定

教学辅助：PPT 教学过程 :

Step1.被动语态基本用法

当句子的主语是动作的执行者时，谓语的形式是主动语态。

当句子的主语是动作的承受者时，谓语要用被动语态。

被动语态由助动词be+过去分词构成，时态通过be表现出来。

主动语态变被动语态的口诀：

宾变主，主变宾，前加by 动变被，看清be,结构分别be+pp We speak English . （主动语态）

→ English is spoken by us . (被动语态)

1.

一般现在时的被动语态：am/is /are +过去分词

His brother washes face every day. →Face is washed by his brother every day. They make shoes in that factory. →Shoes are made (by them) in that factory. Exercises: a). They play football on Sunday. →Football is played by them on Sunday. b). Lucy does the homework in the evening. →The homework is done by Lucy in the evening. 3.一般过去时： was/were +V.(p.p) He looked after the little baby yesterday. →The little baby was looked after by him yesterday. Exercises:

a).They built the tall building last year. →The tall building was built by them last year. b).He took good care of his little brother yesterday.

→His little brother was taken good care of by him yesterday. 4.一般将来时：will + be +过去分词

They will finish the work in ten days. →The work will be finished (by them) in ten days. Exercises: We will have a sports meeting next week.

→ A sports meeting will be had (by us ) next week. Children will take some photos in the schoolyard tomorrow. → Some photos will be taken (by children ) in the schoolyard tomorrow. 5.含有情态动词的：情态动词+ be+过去分词

Amy can take good care of Gina ．

→ Gina can be taken good care of by Amy. Exercises: 1). He can take care of the baby. →The baby can be taken care of by him. 2).Lucy may draw the pictures. →The picture may be drawn by Lucy. 6.现在进行时：am/is/are + being +V（p.p) Some workers are painting the rooms now．

→ The rooms are being painted by some workers now. 7.过去进行时：was/were+being+V(p.p) I was doing my homework at 8:00 last night． → My homework was being done (by me) at 8:00 last night. 8.现在完成时：:have/has + been + V.(p.p) We have made twenty more keys．

→ Twenty more keys have been made by us. Step2:被动语态中的特殊情况

1.不及物动词带介词和介词宾语时，在变为被动语态时，仍然要带上介词。(动词后的介词不可省）

e.g. The students listen to the teacher carefully in class. →

The teacher is listened to carefully by the students in class. e.g. They look after the new students in the school. →

The new students are looked after by them in the school. 2.当动词带有复合宾语(有宾补), 并且宾补是省去“to”的动词不定式时，在被动语态中应加上“to”。（即：主动省to，被动加上to。）

e.g. They make us do all the work. →

We are made to do all the work by them. e.g. We often hear her sing songs. →

She is often heard to sing songs by us. e.g. I saw him walk to school. →

He was seen to walk to school by me. 这些动词真奇怪，主动句中to 离开，被动句中to回

来。（常考词有：make, see, hear, feel, watch, notice 等。) 3.当动词带双宾语时(一个宾语是指人，一个是指物)，将其中指人的宾语提前作被动句的主语时，另一个宾语按顺序照抄下来；如是将指物的宾语提前作被动句的主语，在被动句中则指人宾语前应加“to”或“for”

。

常见加to的动词有: give，send, teach，write, show, pass, ask, tell …

常见加for的动词有: make, buy draw …

e.g. He gives me a flower everyday. 被动1： I am given a flower by him everyday. 被动2： A flower is given to me by him everyday. e.g. My mother bought me a computer. 被动1： I was bought a computer by my mother . 被动2： A computer was bought for me by my mother .

Exercise: The foreign friends gave us some wonderful stamps. 1) _______ ______ _______ some wonderful stamps. 2) Some wonderful stamps _______ ________ _______ _______. 4. 系动词没有被动形式，主动形式表被动意义。常见的有taste（尝起来）， sound （听起来）， feel（摸起来）， look（看起来），smell（闻起来）等.For example: 1) The apple tastes good. 2)The song sounds gentle. 5. 有些动词如:sell（卖）， wash（洗）， write (写）等与副词well（好）， easily（容易地）等连用

，描绘事物的特性，用主动表被动。

For example:1) The coat washes easily. 2) The books sell well Do exercises: 1.The teacher asked Tom to turn on the computer. Tom _______ ________ to turn on the computer. 2.

In this factory women do most of the work. Most of the work _______ ________ by women in this factory. 3.

He can mend the bike in two days. The bike ______ ______ _______ in two days. 4.

.The students in this school study German. German _______ ________ by the students in this school. 5.

Do they often talk about this question? ______ this question often _______ about _______ _______?

Step3: Summary: 各种时态的被动语态构成: 一般现在时： S+am/is /are +done 一般过去时：S+was/were +done

情态动词：S+ can/may/must/should + be+ done 一般将来时：S+ will+be+ done 现在进行时：S+ am/is/are + being + done 现在完成时：S+ have/has + been+ done 过去进行时：S+ was/were+being+ done Step4: Do exercises 1.The students clean the windows of their classroom twice a month.
