1、Section Learning about Language现在进行时的被动语态一、结构am/is/arebeing done二、用法1表示此刻正在进行的被动动作。如：She is being examined by a doctor.她正在接受医生的检查。2表示现阶段正在进行的被动动作，但此动作在此时此刻不一定发生。如：A new station is being built.一个新的车站正在建设中。3表示经常性的被动行为，常和 always,constantly 等词连用。如：He is always being praised by the teacher.他总是被老师表扬。4与部分情

2、态动词连用，表示对正在发生的动作的推测。如：He may be being scolded by his father at the very moment.他此刻也许正被他父亲责骂。三、易错之处因为被动语态的基本构成为 be done，因此，不少学生误将现在进行时的被动语态结构“am/is/are being done”写成“am/is/arebeendone”，造成被动语态结构错误。如：Dont touch the machine when it is been operated.()Dont touch the machine when it is being operated.()机器

3、运转时不要用手触摸。四、特别注意1现在进行时的被动语态可表示根据计划或安排，主语将要承受谓语动词的动作，仅限于 bring,take,send,hold,sing,play等少数及物动词。如：Folk song is being sung next.下面将唱一首民歌。2一些表示状态、心理活动、拥有、存在等的动词，一般不用于现在进行时的被动语态，而用一般现在时的被动语态表示此时此刻或目前主语正承受谓语动词的动作。如：Wang Li,come here.Youre being wanted on the phone.()Wang Li,come here.Youre wanted on the p

4、hone.()王丽，过来，有你的电话。3“介词 in/on/under 等名词”构成的介词短语常含有被动意义，可代替现在进行时的被动语态，此时名词前一般不用冠词。如：The bridge is under repair/construction(is being repaired/constructed)大桥正在建设中。The picture is on display(is being displayed)these days.这张照片这些天一直在展示。五、句型变换现在进行时的被动语态与现在分词的被动式 being done 均可表示此刻正在进行的被动动作，因此它们之间可以进行句型转换。如：

5、Please tell me something about the meeting which is beingheld now.Please tell me something about the meeting being heldnow.(being held 作后置定语)请告诉我此刻正在举行的会议的有关情况。注意：非谓语动词的被动形式表达不同时态的被动意义：(1)to be done 是不定式的被动，表示将来和被动；(2)to have been done 是不定式完成式的被动，表示完成和被动；(3)being done 是现在分词的被动，表示进行和被动；(4)having been

6、 done 是现在分词完成式的被动，表示完成和被动，不作定语和补足语；(5)done 是过去分词，表示完成和被动，作定语、状语、补足语。一、用所给单词或短语的适当形式填空1The camera that _(use)by him nowbelongs to me.2 With the development of science,more new technologies_(apply)in the field of IT.3A new library _(build)and will becompleted next month.4 While the machine _(examine),
