课件14张PPT。Grammar The passive voice using the present continuous tenseGrammar (5m)现在进行时被动语态表示说话时或现阶段某个被动的动作正在进行,谓语动词的形式为“is?/?are?/?am?+?being+过去分词”。如果去掉being,就成为一般现在时被动语态或系表结构。试比较下列句子: Look!?The?children?are?being?taken?care?of?by?
their aunt.
?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 ?现在进行时被动语态也可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.?
下面将唱一首民歌。 A?party?is?being?held?tonight.?
今晚将要举行一场晚会。 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 一些表示状态、心理活动、拥有、存在等的动词(和主动语态一样)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.? 足球现在越来越流行了,?换句话说,它被越来越多的人喜爱。 【误】Football?is?becoming?more?and?more?popular.?In?other?words,?it?is?being?loved?by?more?and?more?people.? 【正】Football?is?becoming?more?and?more?popular.?In?other?words,?it?is?loved?by?more?and?more?people.? 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).?桥梁正在修理中/建筑中。 The?problem?is?under?discussion?(=is?being?discussed)?at?the?meeting.?问题正在会上讨论。? The?telephone?is?in?use?(=is?being?used)?
