现在进行时被动语态五个提醒
一、不可遗漏being
现在进行时的被动语态表示说话时主语正在承受谓语动词的动作，谓语动词的形式为“is/are/am＋being＋过去分词”。如果把being漏掉，就成为一般现在时被动语态或系表结构。试比较下列句子：
Lk！ The children are being taken care f by their aunt.
瞧！孩子们现在正由姑母照看着。
Children are taken gd care f at schl.
孩子们在校被照看得很好。（指通常情况）
The reprt is being written by ne f the best students.
报告正在由一个最好的学生写着呢。
The reprt is well written.
报告写得很好。（系表结构）
二. 表示现阶段
现在进行时被动语态也可以表示目前这一阶段主语正在承受谓语动词的动作。
Many interesting experiments are being carried ut these days.
最近正在进行许多有趣的实验。（说话时，并不一定在进行）
三. 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bring，take，send，hld，sing，shw，play等表示移动的或能用来表示某项活动的少数及物动词）。 A flk sng is being sung next.
下面将演唱一首民间歌曲。
A party is being held tnight.
今晚将要举行一场晚会。
四. 没有进行时被动语态
cntain，include，impress，feel，want，like，lve，satisfy，surprise，wn等一些表示状态、 心理活动、拥有等意义的动词（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。
Xia Wang, cme here. Yu are wanted n the phne. ?
小王，过来，有人打电话找你呢。
Ftball is becming mre and mre ppular. In ther wrds, it is lved by mre and mre peple.
足球现在越来越流行了，换句话说，它被越来越多的人喜爱。
五. 其它形式表示被动结构
“be＋under/in等介词＋名词”结构可代替进行时被动语态。

目前这个城市正受到进攻。
The telephne is in use（＝is being used）nw. 电话正在使用中。
