?瞧!孩子们现在正由姑母照看着。(指现在的情况)Children?are?taken?good?care?of?at?school.
孩子们在学校被照看得很好。(指通常的情况)The?report?is?being?written?by?one?of?
the?best?students.?
报告正在由一个最好的学生写着。
The?report?is?well?written.?
报告写得很好。(系表结构) 现在进行时被动语态的用法:
1. 表示现阶段正在进行的动作?现在进行时的被动语态可以表示目前这一阶段主语正在承受谓语动词的动作。例:Rainforests?are?being?cut?and?burned?at
such?a?speed?that?they?will?disappear?
from?the?earth?in?the?near?future.
热带雨林被砍、烧得这么快,他们将在不
久的将来从地球上消失。
Many?interesting?experiments?are?being
carried?out?these?days.
最近正在进行许多有趣的实验。 2. 表示计划或安排?现在进行时被动语态还可表示按计划、安排主语将要承受谓语动词的动作(仅限于少数及物动词)。例:A?folk?song?is?being?sung?next.?
A?party?is?being?held?tonight.?
It?is?said?that?a?plane?is?being?flown?by?
him?to?America?at?eight?next?Sunday?
morning.?据说下周日早上八点他将开飞机去美国。3. 没有进行时的被动语态的动词一些表示状态、心理活动、拥有、存在等的动词一般不用进行时被动语态,常用一般现在时被动语态表示此时此刻或目前主语承受谓语动词的动作。如:?小王,过来,有你的电话。【误】?Xiao?Wang,?come?here.?You?are?being?wanted?on?the?phone.
【正】?Xiao?Wang,?come?here.?You?are?wanted?on?the?phone.? 4. 其他形式表示被动结构
“be?+under/?in等介词+名词”结构可代替进行时被动语态。例:
The?city?is?under?attack?(is?being?attacked)
at?the?moment.?
目前这个城市正受到进攻。
The?bridge?is?under?repair?/?construction
(=is?being?repaired/?constructed).?
