The Passive Voice 被动语态
一、被动语态的构成形式
1. 被动语态的基本时态变化
1) amisare +done
(过去分词) 一般现在时
2) has have been done 现在完成时
3) amis are being done 现在进行时
4) waswere
done 一般过去时
5) had been done 过去完成时
6)
waswere being done 过去进行时
7) shallwill be
done 一般将来时
8) shouldwould be done 过去将来时
2. 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,在用于被动结构时,可以把主
动结构中的一个宾
语变为主语,另一宾语仍然保留在谓语后面。
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,将宾语变为被动结构中
的主语,其余不动。
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,let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.
3.
非谓语动词的被动语态 ving形式及不定式 to do 也有被动语
态。
例I
don't like being laughed at in the public.
二、 如何使用被动语态
1. 讲话者不知道动作的执行者或不必说出动作的执行者
(这时可省
by 短语)。
例 My bike was
stolen last night.
2. 借助被动的动作突出动作的执行者。
例 I was given ten minutes to decide whether I
should accept the offer.
3. 为了更好地安排句子。
例The well-known person got on the bus and was
immediately recognized
by people. (一个主语就够了)
三、 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 It is
thought that…大家认为, It is
suggested that…据建议。
四、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,catch,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? 这些报纸是如何印出来的呢?
3.
系动词没有被动形式, 但有些表示感受、感官的系动词feel,
sound, taste,
look, 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
,在某些句型中可用动名词和
不定式的主动形式表被动意义 。
1.
在need,want,require,
bear等词的后面,动名词用主动形式
表示被动意义,其含义相当于动词不定式的被动形式。
例The house needs repairing(to be
repaired).这房子需要修理。
2. 形容词worth后面跟动名词的主动形式表
示被动含义,但不能跟
动词不定式;而worthy后面跟动词不定式的被动形式。
例The picture-book is well worth reading.(=The
picture-book is very
worthy to be read.)
3. 在某些“形容词+不定式”做表语或宾语补足语的结构中,句子
的主语或宾语又是动词不
定式的逻辑宾语时,这时常用不定式的主动
形式表达被动意义。
有nice,easy,fi
t,hard,difficult,important,impossible,pleasant,
interesting等。
例This problem is difficult
to work out .(可看作to work out省略了for
me).
4. 在too…
to…结构中,不定式前面可加逻辑主语,所以应用主
动形式表示被动意义。
例This book is too expensive (for me) to buy.
