被动语态的基本结构 尝试总结动词过去分词的变化规则
被动语态的基本结构: be + done (p.p.)+ (by …)
be有各种时态的变化
其否定形式为 be+not+done（过去分词）
动词过去分词的变化规则？
过去分词
Summary 1
规则动词的过去分词
不规则动词的过去分词
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：
e.g. 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。
Activity 2
主动语态如何转化为被动语态？
Active Voice（主动语态）: People grow tea in Hangzhou.
Passive Voice（被动语态）: Tea is grown (by people) in Hangzhou.
主动句： 主语 + 及物动词 + 宾语
被动句： 主语 + be + p.p. + by + 宾语
口诀：
原宾变现主
谓语变被动
加之by引导
一般现在时的被动语态：主语 + am/is/are (not) + done
讨论时间过后，第二组派代表回答。
Summary 2
主动变被动解题步骤:
1. 找宾语 — 即动作的承受者
2. 判断新主语的单复数 — 即be动词的单复数
3. 根据原动词的时态 — 即be动词的时态
4. 修改谓语的时态 — 即原句动词改为过去分词
5. 原句主语 后移 变为 by+宾格/名词
They make shoes in that factory.
Shoes
are
were
made
by them in that factory.
