被动语态专题
? 定义
语态是动词的一种形式,表示主语和谓语之间的关系。
英语有两种语态:主动语态和被动语态
。主动语态表示主语是谓语的执行者。被
动语态表示主语是谓语动作的承受者。
?
被动语态的构成:助动词be+及物动词的过去分词
? 被动语态的时态:
“主动语态变被动语态,时态不变动”,即助动词be
的时态要跟原主动语态中的
时态保持一致。请看下表:
时态
一般现在时
一般过去时
一般将来时
现在进行时
现在完成时
被动结构
amisare+过去分词
waswere+过去分词
willshall be+过去分词
amisare being+过去分词
havehas been+过去分词
含情态动词 canmaymust...
be+过去分词
? 主动语态变被动语态的方法
第一步:先确定主动句的主、谓、宾,找出其中的谓语动词。
第二步:把主动句中的宾语变为被动句的主语,若宾语是人称代词,变宾格为主
格。
第三步:把主动句中的谓语动词变为“助动词be +及物动词的过去分词”, 时态
不变。
第四步:把主动句中的主语变为被动句中介词by的宾语(没必要说出动作的执行
者时,“by
+宾语”在句中常省略。),若主语是人称代词,应把主格变为宾格。
请对比下面的主动句和被动句:
主动语态:They(主语)
grow(谓语) tea(宾语) in the southeast of China.
被动语态:Tea(主语) is grown(谓语) by them in the
southeast of China.
随堂演练(把下列句型改为被动句)
writes a letter every week.
→
Lei mended the broken bike this morning.
→
grow trees every spring.
→
mother cleans our room every morning.
→
补充:
①S + V +IO +DO双宾语的结构变为被动语态时,可
把其中一个宾语变为被动
语态的主语。若将直接宾语变为主语,需根据习惯在原间宾语前加上介词to或
for 。
用to的常见词有:give, show, send, lend,
pass, pay, teach, throw, bring …….
用for的常见词有:design, choose, sing, buy, get, cook
……
1. Mary gave him some books.
He was
given some books by Mary.
Some books were
given to him by Mary.
2. Her father bought her
a new bike.
She was bought a new bike by her
father.

father.
随堂演练:
(1)He gave me a book.
→____________________________________(间接宾语作主语)
→____________________________________
(直接宾语作主语)
(2)My father bought me a new bike.
→____________________________________(间接宾语作主语)
→____________________________________
(直接宾语作主语)
②S+ V+ O+ OC带复合宾语(宾语+宾语补
足语)的结构变为被动语态时,只能
将宾语变为被动语态的主语,宾语补足语不可变为主语。
call him Gina.
→ He is called Gina (by us).
made me happy.
→I was made happy
(by them).
asked me to come here.
→I was asked to come here (by him)
补充:
在主动语态中,使役动词和感官动词后接动词原形(即省to的动词不定式),在变成被动语态时,需将to补上。使役动词let除外。
使役动词和感官动词有:一感(feel), 二听(hear,listen
to),三让(make, have,
let),四看(look at, see,
watch, notice)

playground just now.
