The passive voice
一、英语动词有两种语态：主动语态和被动语态。以下情况使用被动语态： 1.当我们不知道谁是动作的执行者。 2. 或者只需强调动作的承受者时。 基本结构： 一般现在时 一般过去时 一般将来时 情态动词 v.过去式 will/be going to + V.原 情态动词+V原 主动语态 V原/V-s/-es 被动语态 am/are/is +V.pp was/ were + V.pp will/ be going to + be + V.pp 情态动词+be +V.pp 情态动词有： can/could/will/would/shall/should/may/might/must/need/ought to 拓展：现在完成时:have/has +been+V.pp 过去完成时:had+been+V.pp 二、主动语态变被动语态的方法： 宾变主，主变宾（by+宾格），谓语动词be“过分”（be +V过去分词） We speak English.
English is spoken by us 宾变主 谓语（be+pp） 主变by+宾格 三、做题步骤： 1、找出宾语
2、判断时态 时态一致 3、检查三个一致性 句式一致 主谓一致
I must send this letter to his school soon. 主变by+宾格(放在时间状语之前) This letter must be sent to his school by me soon . ▲做选择题技巧：
1.选项出现被动态，优先考虑被动态。 2.注意主语与动词的关系：是主动还是被动 3.happen、take place 没有被动语态。
4.变为被动语态,不能丢掉尾巴上的介词,常用的有look after, take care of, cut down, laugh at, talk about, turn on等 单项选择：

English ______ ________ _____ Tom every day. 2. I__________(clean) the windows yesterday.

▲ give/ teach /send/ pass/buy /offer/return/tell等接双宾语的动词（一人一物即give sb sth/send sb sth/buy sb sth ），改为被动时通常物做主语，如人做主语须根据动词的固定搭配(give sth to sb/buy sth for sb)在人前加to或for(buy)。
We gave him some books.
Eg:人：He was given some books(by us). 物：Some books were given to him (by us) 把下列句子由主动变成两个被动的句子： 1.They gave him two books yesterday . He _______ _______ _________ __________ by them yesterday .
Two books _______ _______ _________ __________by them yesterday. 2.She bought me a football yesterday .
I _________ _________ ______ ____________ by her yesterday.
A football _________ _________ ______ ____________ by her yesterday. ▲中考链接
