被动语态的考点解析
掌握被动语态的用法
教学容
【温故知新】
批注:我们见过很
多街头艺人,在大街上画出的立体画非常的逼真,很多人都会认为是真的,而从旁边绕过
去,所以我们被
欺骗啦! We are cheated! 这样的表达,就是我们今天要讲的容——被动语态
【知识梳理】
知识点1:被动语态的基本知识
1. 语态:英语的语态是通过动词
的形式表现出来的,用来表明主语与谓语动词之间的关系,英语的动词有
两种语态形式,即主动语态和被
动语态。如果主语是动作的执行者,谓语动词用主动语态。如果主语是动作
的对象,谓语动词用被动语态
。
2. 主动语态与被动语态的转化:
①将主动语态的宾语改为被动语态的主语;②将主动
语态的谓语动词改为“be+过去分词”结构;③将主动
语态的主语改为介词by之后的宾语,放在谓语
动词之后(有时可省略)。
例: We visited that factory
last summer.
?
主动语态
文案
标准
主语 谓语 宾语 状语
That factory
was visited by us last summer
?
被动语态
主语 谓语 宾语 状语
3. 用法:
被动语态常用于以下两种情况:
(1)不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者;
例:This
cloth is made of cotton.
(2)强调动作的承受者。
例:Her bike is stolen .
知识点2:被动语态在各种时态下的构成
时态 结构 例句
We are
taught English by her.由她教我们英语。
A present was
given to me by Mary.玛丽给了我一件礼物。
一般现在时 amisare
+过去分词
一般过去时 waswere+过去分词
一般将来时 willshallbe
going to The desk will be mended by him.这桌子将由他修理。
be+过去分词
现在进行时 amisare +being + 过去
分词
过去进行时 waswere +being + 过去
分词
现在完成时
havehas been+过去分词
The talk was being given at
this time yesterday.昨天这个时
在作报告。
The flowers
have been watered.这些花已经被浇了。
The walls are
being painted now.正在粉刷墙壁。
文案
标准
过去完成时 had been+过去分词 She said this lift had
never been used.
过去将来时 wouldshouldbe going to
The film would be shown again sometime next week.
这部电
be+过去分词
情态动词 情态动词+be+过去分词(其
时态及句型的变化
仅由情态
动词完成,过去分词部
分不变)
影下周的某个时候又将上映。
例1:Tables can be made of stone.桌子可由石头制造。
例2:Tables could be made of stone at that time.
那时桌子可由
石头制造。(一般过去时)
例3:Can tables be made
of stone? 桌子能用石头制造吗?(疑
问句)
批注:这里可以跟学生一起回顾一下动词的原形、过去式和过去分词,避免混淆。
【例题精讲】
单选题
例1:(2012) — Our
classroom____________every day.
— So it is. It's our duty to keep it clean and
tidy.
A. cleans B. is cleaning
C. is cleaned D. cleaning
解析:答案C。our cla
ssroom做主语,很明显是“被打扫”,并且根据语境是一般现在时态,所以用一
般现在时态的被动
is cleaned。
例2:(2013)The mobile phone has
influenced people’s life a lot since it _________.
A. invents B. invented C. is
invented D. was invented
解析:答案D。考查动词时态和语
态。句意:自从手机发明后,它在很大程度上影响了人们的生活。根据句
意判断用一般过去时,手机与动
词invent在逻辑上是被动关系,所以用一般过去时的被动语态。
文案
标准
例3:(2013)It is said that an
Asian Culture Village inside the AYG,
Village in Nanjing in
the coming Asian Youth
Games period.
A. builds B. is building C.
will be built D. was built
解析:答案C。考查动词的被动语态用法。an Asian Culture Village(亚洲
文化村)与动作build构成被动
关系,所以应使用被动语态,故排除A、B项;又据句中in
the coming Asian Youth Games
period可
知为将来时间,所以选择答案C。
例4:(2013呼和浩特)
People who ________ to the party are very excited.
A. have invited B. has been invited C.
will invite D. have been invited
解析:答案D。考
查被动语态的用法。根据句意“已经被邀请去参加聚会的人非常激动。”可以判断须用现
在完成时的被动
语态。B和C选项为主动语态,但是动词invite没有宾语,故排除;而B选项中,has和
主语p
eople不能搭配。所以选择答案D。
例5:(2013黄冈)—How often
do I need to feed the dog?
— It ___ food every day, or it will be hungry.
A. must give B. must be give C. must
be given D. must be gave
解析:答案C。考查情态动词的被动语态。
它每天必须被喂食,应用被动语态,其构成是be+过去分词,故
选C。
例6:
The new suspension bridge ___ by the end of last
month.
A. has been designed B. had been
designed C. was designed D. would be
designed
文案
标准
解析:答案B。根据“by
the end of last month”,所以用过去完成时,又因为这座新桥是被设计的,
所
以综合来看,用过去完成时的被动语态。
例7:用括号动词的适当形式填空
_______________ (tell) the good news as soon as it
arrived.
2.A lot of work
__________________(do) for the poor kids in the
past few years.
book ________________ (write)
by the young girl several years ago.
the
tickets __________(sell) out when we got to the
cinema.
5.A new building __________(build) at
our school now.
6.I don't believe you've
already finished reading the book which
________(lend) to you this
morning!
解析:
1. 答案was told。首先根据“as soon as it arrived”,判断时态
是一般过去时,而句意是“她被告知这个
好消息”,所以用一般过去时的被动语态。
2.
答案has been
done。由时间状语可知需要用现在完成时态,句意是“大量工作已经被做”,所以用被
动语态。
3. 答案was written。“several years
ago”,可判断时态为一般过去时,“书是由一个年轻女孩所写”,应
用被动语态。
4.
答案had been sold。“在他们到达电影院的时候,票已经卖完了”,这里“到达”已经是过去时,
所以
票卖完了是在到达之前发生的,所以用过去完成时的被动语态。
5. 答案is
being
built。由now可知需用现在进行时态,新桥是“被建造”,所以用现在进行时态的被动
语态。
6. 答案 was lent。由this
morning可知时态为一般过去时,而书“被借出”,用被动语态。
文案
标准
例8:把下列句子改为被动句
1. John
drew a beautiful horse last week.
2. The
children will sing an English song.
3. People
use metal for making machines.
4. He asked me
to do that for him.
5. They sold out the light
green dresses.
答案:1. A beautiful horse
was drawn by John last week.
2. A
English song will be sung by the children.
3. Metal is used for making machines by people.
4. I was asked to do that for him.
5. The light green dresses were sold out by them.
例9:用括号所给动词的正确形式填空。
's said that the
long bridge______________(build)in two months.
to have the meeting ______________
(discuss)now.
language _______the most
widely_______(speak)in the world?
lost
boy_____________(not find)so far.
year a
large number of trees______________(cut)down.
解析:
1.答案will be built。根据后面的in two months可判
断时态为一般将来时,再根据主语是bridge,可
知桥是被建造的,所以用一般将来时的被动语态。
文案
标准
2.答案is being
discussed。这里主语是疑问词引导的不定式做主语,谓语动词用三单形式,
再看最后的
时间状语是now,所以用现在进行时的被动语态“is being
discussed”。
3. 答案is spoken。句意是“哪种语言在全世界最广泛的被说”
,这是一种常识性的是奇怪,所以用一般现
在时的被动语态。
4. 答案hasn’t
been found。首先根据后面的“so
far”,判断时态为现在完成时,再根据主语是单数,
可以判断用“hasn’t been
found”。
5. 答案were cut。时间状语“last
year”,可判断时态为一般过去时,主语是很多树,所以用were
cut,
这里需要注意cut的原形、过去式和过去分词拼写是一样的。
例10:单选题
1. The decision about the price
______ in a few days. So they have to
wait.(2013年白下区中考一模)
A. is made B. was
made C. is being made D. will be made
解析:答案D。根据后面“in a few
days”,判断是一般将来时。这个决定是“被做”,所以用一般将来
时的被动语态。
2.
If city noises ____ from increasing,people will
have to shout to be heard even at dinner.
A.
are not kept B. are not keep C. do not keep
D. do not kept
解析:答案A。这里首先是条件状语从句,遵循“主将从现”原则,所
以if从句里面用一般现在时态的被动。
3. The fifth generation
computers, with artificial intelligence, ____and
perfected now.
A. developed B. have
developed
C. are being developed D. will
have been developed
解析:答案C。句意是“第五代电脑正在发展和完善”,有
被动意思,而且有now这个时间状语,所以用
现在进行时态的被动语态。
4. ---
____ the sports meet might be put off.
文案
标准
--- Yes,it all depends on the
weather.
A. I've been told B. I've
told C. I'm told D. I told
解析:答案A。这
里说的是运动会这个消息,我是“被告知”的,所以用被动语态,所以排除B和D。再根
据句意,被告知
这个事情已经发生了,强调对现在所造成的影响,所以需要用现在完成时态。
5. I need
one more stamp before my collection ___.
A.
has completed B. completes C. has been
completed D. is completed
解析:答案D。这里也需遵循“主将
从现”原则,before引导的从句中需用一般现在时,所以用一般现在
时的被动语态。
6. Rainforests ___ and burned at such a speed
that they will disappear from the earth in the
near
future.
A. cut B. are cut
C. are being cut D. had been cut
解析:答案C。句意是“雨林正在以很快的速度被砍伐和焚烧”,所以用现在进行时的被动语态。
7. When a pencil is partly in a glass of
water, it looks as if it ____.
A. breaks
B. has broken C. was broken D. had
been broken
解析:答案C。这里的意思是“当铅笔一端被放在一杯水里的时候,看起来就
好像被折断了”,又因为这里
涉及as
if后面需要用虚拟语气,所以时态需比主句往后退一格,因此用过去时态的被动语态。
【举一反三】
知识点1:
①不及物动词不用于被动语态,如appear, rise, come out, happen,
occur, lie, take place等不及物动词
不能用于被动语态。
例1:Great changes______________place. Many new
schools ______________.
文案
标准
A. have taken, have been opened B. take,
are open
C. are taken, open D. have
been taken, are opened
解析:答案A。因为take place没有被
动语态,所以排除C和D,又因后句中很多新学校开了,这里需要
被动,而且表示到现在为止已经开了,
所以用现在完成时态的被动语态。综合选择A。
例2:A strange thing
_____ in our school yesterday.
A. was
happened B. has been happened C. happened
D. was going to happen
解析:答案C。因为happen没有被动语态,
所以排除A和B。又有yesterday,可判断时态是一般过去
时,所以选C。
②表状态动词不用于被动语态,常见的有:hold, have, cost, contain,
become, look like等
例1:这本书花了我20元。(用cost翻译)
__________________________________________________
__
解析:答案The book cost me 20
yuan。因为主语是书,很可能有的同学会写成“The book was cost
20
yuan.” 可是cost这里表状态,不用于被动态。
例2:That suit
__ over 60 dollars.
A. had costed B.
costed C. is costed D. cost
解析:答案
D。因为cost这个词不需要用被动语态,所以这里的主语是单数,可以用costs(一般现在时)
或cost(一般过去时),根据选项,只能选D。
知识点2:主动形式表被动意义。
1)某些感官动词和系动词接形容词可以表示被动意义。如:look, smell, taste,
feel, prove, wear, sound
文案
标准
等
例:Her bedroom looks very clean and
tidy.她的卧室看起来非常干净和整洁。
2)某些作表语的形容词后,用不定式主动形式表示被动意义。
例:The
conversation is hard to understand.对这话很难理解。
The fish is not easy to fish.鱼不容易钓。
The
passage is difficult to read.这段文章很难读懂。
3)动名词的主动形式表示被动语态。如:need, require,
worth等,并且可相互转化,如need doing = need
to be done。
例:The book is worth reading.这本书值得一读。
The children need looking after.孩子们需要照看。
4)write, sell, wash和read和副词连用,主动语态表被动意义。
例:The pen writes smoothly. 这笔写起来很顺手。
The article reads well. 这篇文章读起来很好。
例1:--- Do
you like the material?
--- Yes, it ___
very soft.
A . is feeling B . felt C . feels
D . is felt
解析:答案C。这道题首先根据选项看出考查的是feel
的用法,它属于系动词,无被动,无进行时,所以
排除 A,D,然后根据前一句话的时态确定选择C。
例2:It is difficult for a foreigner ____
Chinese.
A. write B. to write C. to be
written D. written
解析:答案B。作表语的形容词difficult后不定式to write主动形式表示被动意义。
例3:The composition doesn’t____any more.
A. need to be correcting B. need to be
corrected
C. need be corrected D.
need be correcting
解析:答案B。因为need doing sth =
need to be done,这里只有B正确,如果变成need doing sth,
文案
标准
可以换成need correcting。
例4:--- What do you think of the book?
---Oh, excellent. It's worth ___ a second time.
A . to read B . to be read C . reading
D . being read
解析:答案C。本题通过后面的回答可以很明显看出是be
worth的考点,首先后面接doing,然后根据它
的主动表被动的特点,排除D。
例5:The kind of cloth ________ well.
washed washing
解析:答案C。本题的考点是w
ash后接副词,表示耐洗,主动形式表被动语态,因为cloth不可数,所以
谓语动词用三单形式。
知识点3:及物动词后跟双宾语的句子,被动语态有两种。
常见的有:
主动语态
bring sb. sth. 把某物带给某人
lend sb.
sth. 把某物借给某人
offer sb. sth. 将某物给某人
pass
sb. sth. 把某物递给某人
pay sb. sth. 付给某人某物(钱)
send sb. sth.把某物送给某人
sell sb. sth.把某物卖给某人
show sb. sth. 拿某物给某人看
teach sb. sth. 教某人某物
tell sb. sth.告诉某人某情况
buy sb. sth. 为某人买某物
被动语态
sb be brought sth sth be brought to
sb
sb be lent sth sth be lent to sb
sb be
offered sth sth be offered to sb
sb be passed
sth sth be passed to sb
sb be paid sth sth be
paid to sb
sb be sent sth sth be sent to sb
sb be sold sth sth be sold to sb
sb be
shown sth sth be shown to sb
sb be taught sth
sth be taught to sb
sb be told sth sth be
told to sb
sb be bought sth sth be bought for
sb
文案
标准
make sb. sth.为某人制作某物
例1:同义句转换
sb be made sth sth
be made for sb
My parents gives me a birthday
present every year! (变被动语态,两种表达)
____________
__________________________________________________
______
_______________________________________
_____________________________
解析:答案I am given
a birthday present by my parents every year. A
birthday present is given
to me by my parents
every year. 分别把宾语me和a birthday作为主语。
例2:He
told us a story.(变被动语态,两种表达)
_________________
__________________________________________________
__
___________________________________________
__________________________
解析:答案We were told a
story(by him)或A story was told to us by
him.分别以we和a story
做主语,主语谓语动词的形式以及时态。
知识点4:感官动词see,hear,watch,feel,notice及使役动词let,
make, have等,动词后省略to不定式,
变为被动语态时,应加上不定式符合to.
例:I always see the boys play in the park.
(变成被动语态)
The boys are always seen to play
by me in the park.
例1:He was made ___ a lot of
work.
A. do B. to do C. did
D. doing
解析:答案B。make的用法是make sb do
sth,在被动的情况下,需把省略的不定式to还原。所以被
动形式为be made to do
sth。
例2:He was seen something from
the shop .
文案
标准
A. steal
B. to steal C. to be stolen D. stealed
解析:答案B。see的用法,see sb do sth和see sb doing
sth,被动态是sb be seen to do sth和sb
be seen doing
sth,所以根据选项来看,这里选择B。
知识点5:一些动词短语用于被动语态时,动词
短语应当看作一个整体,而不能丢掉其中的介词或副词。
例:We can't
laugh at him. →He can't be laughed at by us.
例1:翻译
1. 从来没有听说过这件事情。
________________
_______________________________________
2.
我妹妹由奶奶照顾的很好。
_________________________________
______________________
答案:1. Such a thing has
never been heard of before.
2. My sister
will be taken care of by Grandma.
例2:单选题
1. I think much attention ____your
pronunciation.
A. must be paid to B. ought
to paid to C. must pay to D. should be
paid
解析:答案A。首先attention作主语,后面需接被动语态,所以先排除B和C。又因为pay
attention to
这个动词短语,在被动语态时,后面的to不可以丢掉,所以选A。
2. Our teacher ______ carefully.
A.
should be listened to B. should be listen
C. be listened D. is listened
解析:答案A。首先our teacher作主语,后面表示“被听”,需接被动语态,又因为是单数
,所以先排除
C。又因为listen
to这个动词短语,在被动语态时,后面的to不可以丢掉,所以选A。
