e.g. A house is being built by the workers.
2. 结构
1）肯定形式：am/is/are＋being＋过去分词
The house is being painted.
2）否定形式: am/is/are＋not＋being＋过去分词
The trees are not being watered.
3）疑问形式: Am/Is/Are＋主语＋being＋过去分词？
Am I being watched over

is being taken care of
is being studied
is being interviewed
（2）表示现阶段正被进行的动作，但此动作在此时此刻不一定正在发生。
—Could I use your car please
—Mine is being repaired by the workers.
——我能用你的车吗？
——我的车正在被工人们修着。
（3）少数及物动词的进行时表示按计划、安排将要承受某个动作。

A party ___________ (held) tonight.
2.下面将唱一首民歌。
A folk song ___________ (sing) next.

我感到很迷惑，我们商店的商品老是被偷。
(5)不用进行时的被动语态
一些表示状态、心理活动、拥有、存在等的动词(例如：have,want,need,love等)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。
【练习】判断正误。
