自给自足读音-一块什么填空
被动语态通常为十种时态的被动形式,
被动语态由be＋过去分词构成，be随
时态的变化而变化。
以do为例，各种时态的被动语态形式为：
1) amisare +done
(过去分词) 一般现在时 例Visitors are requested not
to
touch the exhibits.
2） has have been done
现在完成时 例All the preparations for the
task
have been completed, and we're ready to start.
3） amis are being done 现在进行时 例A new cinema
is being built
here．
4） waswere done
一般过去时 例I was given ten minutes to decide
whether I should reject the offer.
5）
had been done 过去完成时 例 By the end of last year,
another new
gymnasium had been completed in
Beijing.
6） waswere being done 过去进行时 例A
meeting was being held when
I was there.
7） shallwill be done 一般将来时 例Hundreds of
jobs will be lost
if the factory closes. 8）
shouldwould be done 过去将来时 例The
news would
be sent to the soldier's mother as soon as it
arrived.
9） shallwill have been done
将来完成时（少用） 例The project will
have been
completed before July.
被动语态的特殊结构形式
1)带情态动词的被动结构。其形式为：情态动词＋be＋过去分词。 例The baby
should be taken good care of by the baby-
sitter.
2) 有些动词可以有两个宾语 例His mother gave
him a present for his
birthday. 可改 为 He was
given a present by his mother for his birthday.
3) 当“动词+宾语+宾语补足语”结构变为被动语态时， 例Someone caught
the
boy smoking a cigarette. 可改为The boy was
caught smoking a cigarette.
4）在使役动词have,
make, get以及感官动词see, watch, notice, hear, feel,
observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为
被动结构时，要
加to。
例Someone saw a stranger walk into the
building. 可改为A stranger was
seen to walk into
the building.
5) 有些相当于及物动词的动词词组，如“动词＋介词”，“
动词＋副词”等，也
可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。 例The meeting is to be put off till
Friday.
非谓语动词的被动语态
v.+ing 形式及不定式 to
do 也有被动语态(一般时态和完成时态) 。 例I
don't like being
laughed at in the public.
It is said
that+从句及其他类似句型
一些表示“据说”或“相信”的动词如believe, consider,
expect, report, say,
suppose,
think等可以用于句型“It＋be＋过去分词＋that从句”或“主语＋
be＋过去分词＋to
do sth.”。有： It is said that?
据说
,It is
reported
that?
据报道
，It is believed
that?
大家相信
，It is hoped
that?
大家希望
，
It is well known
that?
众所周知
，It is thought
that?
大家认为
，It is
suggested
that?
据建议
。 例It is said that the boy has
passed the
national exam. （＝The boy is said to
have passed the national exam. ）
谓语动词的主动形式表示被动意义
1. 英语中有很多动词如 break，cat
ch，clean，drive，lock，open，sell，
read，write，wash等
，当它们被用作不及物动词来描述主语特征时，常用
其主动形式 表达被动意义,主语通常是物。
例 This kind of cloth washes well.
注意：主动语态表被动强调的是主
语的特征，而被动语态则强调外界作用造成的影响。
试比较：The door won't
lock． （指门本身有毛病） The door
won't be locked． （指不会有人来
锁门, 指“门没有锁”是人的原因）
2. 表示“发生、进行”的不及物动词和短语，如：happen, last,
take place,
break out, come out, come about,
come true, run out, give out, turn
out
等以主动形式表示被动意义。
例 How do the
newspapers come out? 这些报纸是如何引出来的呢？
3.
系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound,
taste,
book, feel等在主系表结构中常以主动形式表示被动意义。 例
Your
reason sounds reasonable 五、非谓语动词的主动形式表被动意义
