被动语态被动语态的构成
被动语态由“助动词be+及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以teach为例说明被动语态在各种时态中的构成。
一般现在时:am/is/are+taught
一般过去时:was/were+taught
一般将来时:will/shall
be+taught
现在进行时:am/is/are
being+taught
过去进行时:have/has
been+taught
现在完成时:have/has
been+taught
注意:区分被动语态与“be+过去分词”结构
be+过去分词”并不一定都是被动语态,有时是系表结构。被动语态,动作的对象是主语;当“be
+过去分词”表示主语所处的状态时为系表结构,be是连系动词。be后面的过去分词是表语,相当于形容词。其区分办法如下:
1,
如果强调动作或句中有介词by引导出动作的执行者,该句一般为被动语态。The
glass
is
broken.(系表结构)
The
glass
was
broken
by
the
boy.(被动语态)
2
,如果句中有地点、频率或时间状语时,一般为被动语态The
magazine
is
published
in
Shanghai.。(被动语态)The
door
is
locked.(系表结构)The
door
has
already/just
been
locked.(被动语态)The
shop
is
opened.(系表结构)
The
shop
is
opened
at
8
a.m.
everyday.(被动语态)
3
,被动语态除用于一般时态和完成时态外,还可以用于其他各种时态,而系表结构中的系动词be只有一般时态和完成时态。
三、被动语态的用法
1
不知道或没有必要说明动作的执行者是谁。
Some
new
computers
were
stolen
last
night.
This
book
was
published
in
1981.
2
强调动作的承受者,而不强调动作的执行者。
This
book
was
written
by
him.
Eight
hours
per
day
for
sleep
must
be
guaranteed.
四、主动语态变被动语态的方法
1
把主动语态的宾语变为被动语态的主语。
2
把谓语变成被动结构(be+过去分词),根据被动语态句子里的主语的人称和数,以及原来主
动语态句子中动词的时态来决定be的形式。
3
把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。All
the
people
laughed
at
him.=
He
was
laughed
at
by
all
people.
They
make
the
bikes
in
the
factory.=
The
bikes
are
madeby
themin
the
factory.
五、含有情态动词的被动语态
含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留。
