一般过去时的被动语态
2.
一般过去时的被动语态的基本用法
用
法
示
例
表示过去某一具体时间发生的动作，且句子的主语是谓语动词动作的承受者
The
house
was
built
in
1990.
这所房子建于1990年。
讲述发生在过去的动作，且不知道动作的执行者
He
was
honored
with
the
name
“
Father
of
Hybrid
Rice”.
他被授予“杂交水稻之父”的称号。
3.
含双宾语和复合宾语的主动句变为被动语态的方法
①含有双宾语的主动句变为被动语态时，通常把指
“人”的间接宾语变为主语，而指“物”的直接宾语则不变。
He
gave
me
a
book
yesterday.
→
I
was
given
a
book
(by
him)
yesterday.
②
如果要把指“物”的直接宾语变为主语，则在间接宾语前加to或for。
I
brought
him
some
food.
→
Some
food
was
brought
to
him
(by
me).
③含有复合宾语的主动句变为被动语态时，要将其中的宾语变成主语，宾语补足语不变。
Jim
asked
Tom
to
go
for
a
walk.
→
Tom
was
asked
(by
Jim)
to
go
for
a
walk.
④
如果宾语补足语是不带to的动词不定式，主动语态变成被动语态时要加上不定式符号
to。
We
often
heard
Kate
sing
in
the
room.
→
Kate
was
often
heard
to
sing
in
the
room
(by
us).
4a
Rewrite
the
sentences
using
the
passive
voice.
【点拨】原句为一般过去时态，原句的谓语动词为sold，宾语为the
fridge；改为被动语态时，应将the
fridge作主语，谓语动词用was
sold的形式。
1.
They
sold
the
fridge
at
a
low
price.
The
fridge
was
sold
at
a
low
price.
【点拨】分析原句的句子结构可知，stole是谓语动词，my
camera是句子的宾语；改为被动语态句时，应将my
camera作句子主语，谓语动词用was
stolen的形式。
