四、使用现在进行时的被动语态应注意的问题
1．不可遗漏being
现在进行时的被动语态中，be为第一助动词，being为第二助动词，缺一不可，且位置不可互换。此结构若缺少being，则就成为一般现在时的被动语态或系表结构。试比较：
The reprt is being written by the best student.
报告正在由一名最好的学生写着。
The reprt is well written.
这份报告写得很好。(系表结构)
2．不可遗漏介词
take care f，lk after，talk abut，think f等动词短语用于现在进行时的被动语态时，其中的介词不可省略。
Lk！The children are being taken care f by their aunt.
瞧！那些孩子正由他们的姨妈照看着。
3．没有现在进行时的被动语态的动词
非延续性动词、表示存在意义、所属关系、静态特征的动词以及系动词不用于现在进行时的被动语态。
The bk belngs t him.
这本书是他的。
4．“be(am/is/are)＋under/in＋n.” 结构
有时可相当于现在进行时的被动语态。
The bridge is in use.
＝The bridge is being used.
这座桥正在使用。
