Practice
Fill in the blanks according to grammar focus.
当主语为动作的执行者时，谓语的形式为主动语态；
当主语为动作的承受者时，谓语要用被动语态。
被动语态
定义
eg: Many people speak English.
English is spoken by many people.
动作的执行者
动作的承受者
（1）不知道或没必要指出动作的执行者。
These books are written for children.
（2）强调动作的承受者。
Calculator can't be used in the math exam.
计算器不能用于数学考试。
（3）作客观说明时，常采用一种被动语态结构。
It is\was said\believed\reported +that … …
用法
It is said that the story of Chang’e is the most touching.
句型
1. 肯定句: 主语 + be + V-ed + (by…)
2. 否定句: 主语 + be + not + V-ed + (by…)
3. 一般疑问句: Be + 主语 + V-ed + (by…)
特殊疑问句:疑问词 + be + 主语 + V-ed + (by…)
构成
助动词 be ＋ 及物动词的过去分词
助动词 be 有人称、时态和数的变化
动词过去分词的变化:
1.规则动词的过去分词：
1)一般情况在动词原形后加-ed
watch---watched
2)以不发音e结尾的加-d
practice---practiced
3)以辅音加y结尾的，去y变i加-ed
study---studied
4)以重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加-ed
stop---stopped
drop---dropped
英语重读闭音节就是闭音节中为重读音节的音节，重读闭音节中元音字母不是发它本身的字母音，而是发短元音。
2.不规则动词的过去分词：
如：am/is/are______ was/were_____
have/has_____ do_____
go_______ write______
eat____ leave_____
drink______ take_____
break______ speak______
steal______ see______
give______ get______
bring______ know______
had
done
gone
been
been
written
eaten
left
drunk
taken
broken
spoken
stolen
seen
given
gotten/got
brought
known
规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。部分不规则动词的过去分词形式也和过去式一样。
主动语态变被动语态解题步骤
1. 找宾语 ----即动作的承受者
2.把谓语变成被动结构（be＋过去分词）:
判断宾语的单复数 ----即be动词的单复数,原句动词改为过去分词
3. 修改原句的主语 ----即by+ 主语/ 宾语.
People grow tea in Hangzhou.
Tea is grown (by people) in Hangzhou.
宾语
主语
谓语
一般现在时的被动语态
1.在主动语态句中动词make、have、let、see、watch、 hear、feel等后接动词不定式作宾语补足语，动词不 定式不加to。 但变成被动语态时后面的不定式都须加上to。
注意
例如： (1) The boss makes them work ten hours a day.

(2) Tom lets his little sister water flowers every day.
→ They are made to work ten hours a day.
→ His little sister is let to water flowers every day by Tom.
主动语态变为被动语态的注意事项：
2. 含有双宾语的句子，主动句中的间接宾语或者直接 宾语都可变为被动语态中的一个主语，另一个保留不变。变为主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to 或 for。
常用双宾语的动词：show/give/offer/send /bring/ lend/teach/buy
例如：The teacher gives the pupils some advice.
直接宾语
间接宾语
→The pupils are given some advice by the teacher.
→Some advice is given to the pupils by the teacher.
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。
4. Most of the earth’s surface __________ (cover) by water.
5. The classroom ___________ (clean) by the students every day.
1. Children under 18 _____________ (not allowed) to watch this show without their parents.
2. We _______ (pay) by the boss on the last Friday of each month.
