油酥是什么-羞耻近义词
The Present Perfect Passive Voice
(现在完成时的被动语态)
By Ms Du
一.构成:现在完成时被动语态的结构就是:
现在完成时态和被动语态结构的叠合.
主动语态 被动语态
现在完成时
havehas done havehas been done
试比较以下几组句子的谓语结构:
1) 主动句:He has repaired the
machine for two hours. (他修理这台机器已有两小时了)
被动句:
_____________________________________.
(这台机器已修了两小时了)
2). 主动句:The teacher has
borrowed the books. (老师把那些书借走了)
被动句:
_______________________________.
.
(那些书被老师借走了)
二.现在完成时被动语态的概念

1) 动作
_________
,强调对现在造成的影响或结果:
2)主语与谓语动词之间为
__________
。如:
Our
classroom has been cleaned, you needn't clean it
now.
析:该句强调教室已被打扫,对现在造成的影响是教室是干净的,强调这个影响,你就没必要再打扫了。

。如:

__________
。

door has been locked. 门已经被锁上了。(结果是现在没人能够进去)
3). 动作或状态始于过去, 持续到现在, 并可能持续下去,常与
__________
引导的时间状语连用,或用于
“
__________
”句型中。如:

4).
用在
____________________
中, 表示将来某时已完成的动作。如:

finished. 工作一完成我们就立即动身。
四.使用现在完成时被动语态注意事项:

never, hardly, seldom等副词置于

2). 并不是所有动词都有被动语态

(现在完成时的被动语态)
By Ms Du
happen, take place, break out,
belong to, cost,
last等
____________________
无被动语态。如:
[误] Great changes have been taken place in China
since 1978.
[正] Great changes have taken
place in China since 1978.
3).但许多不及物动词加介词或副词构成的短语动词,相当于及物 动词,也可以有被动语态。但短语
动词是一个
不可分割的整体,变为被动语态时,不可丢掉构成短语的
____________
________
。如:
eg 1) The child has been taken
good care of by Grandma Wang all these years.
2)A notice has been put up on the wall.
4.
1)双宾语的动词变为被动语态时,常将
__________
变为主语;但若直接将
__________
变为主语,则需要在
间接宾语前加上适当的
_________
_
(to 或for)。
eg (1)His parents have
given him a new bike recently.
被动
_______
has been given
____________
(by his parents) recently.
被动
_______
has been
given
____________
(by his parents)
recently.
4.2)带有复合宾语的动词在变为被动式时,只能够把
_______
___
变为主语,而原来的宾语补足语则变为相应的
__________
。
eg (2)I have asked him to post the letter.
被动_______________________________________
五、现在完成时被动语态的否定式和疑问式。
从现在完成时被动语态结构has
have been done可以看出
__________
为助动词,因此现在完成时被动
语态的各
种句型变换均应借助于
__________
来完成。构成否定句时直接在h
ashave后面加
__________
,构成一般疑问
句时将
_____
_____
提前,构成反意疑问句时,附加问句借助
__________
。如:
His homework hasn’t been finished.
他的家庭作业还没有写完。
Has this bridge been finished?
这座桥竣工了吗?
The blackboard has been cleaned,
hasn’t it? 黑板已经擦过了,是吗?
六、现在完成时被动语态例题讲解
[例1] Paper money________for over a thousand
years.
A. used B. has been used C. has
used D. is using
[析] 主语和谓语是被动关系,而且时间状语是一个时间
段,根据题意,谓语动词所要表示动作可能还要继续
下去,符合现在完成时,所以应该是现在完成时的被
动式。答案是B。
[例2] —We want to sit at the table
near the window. —I'm sorry,but it________already.
A. has taken B. took C. was taken D. has
been taken
The Present Perfect
Passive Voice (现在完成时的被动语态)
By Ms Du
[析]
从题干中的答语知道,座位已经有人坐了,说明结果。所以应该用现在完成时的被动式。答案是D。
[例3] —________the letter________to Mr Black?
—No. It's still on the desk.
A. Has; given
B. Will; be given C. Was; given D. Has; been
given
[析] 此题是一道问答情景题。问话人想知道的是动作的结果,所以应该是现在完成
时的被动式。其疑问式是
把这一结构中的助动词have或has提前,所以正确答案为是D。
[例4] —How long________at this job?
—Since 1990.
A. were you employed B. have
you been employed
C. had you been employed
D. will you be employed
[析] how long
引导的是一个特殊疑问句,从how long和 since
1990我们可以确定应该是现在完成时,再从意
义上看,应该使用被动语态,所以答案应该是B。
[例5] The reason for all the changes being
made________to us yet.
A. as not explained
B. has not been explained
C. didn't explain
D. were not explained
[析] the reason 是主语中心词,
它和谓语explain之间是被动关系;题干的意思是:还没有给我们解释作出变
化的理由。应该是现
在完成时的被动式的否定式。答案是B。
[例6] Great
changes________in my hometown and a lot of
factories________.
A. have been taken
place;are being set up
B. have taken
place;have been set up
C. are taken
place;had been set up
D. had taken
place;will be set up
[析] take place
是不及物动词词组,因此没有被动语态;而factories和set
up之间是被动关系;根据题干上下文可
以看出,都应该是现在完成时,所以答案是B。
