Am I being watched ver?
4）特殊疑问句的形式: 把特殊疑问词放在一般疑问 句前面。

3. 主动语态变被动语态的原则
例：They are building nine parks.
原句主语变为by短语宾语变为主语 谓语由主动变为被动
原句意思不变 原句时态不变 原句主谓宾以外成分不变
Nine parks ______________ by them. Hw many parks ____________?
are being built
4. 现在进行时的被动语态基本用法：
（1）表示现在正在进行的被动动作。
is being taken care f
is being studied
being interviewed
（2）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。
例：1.今晚将要举办一场晚会。 An party ___________ (held) tnight.2.下面将唱一首民歌。 A flk sng ___________ (sing) next. 3.据说下周日早上八点他将开飞机去。 It is said that a plane___________(flw)  by him t America at eight next Sunday  mrning. 
is being held
is being sung
is being flwn
(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。
【练习】判断正误。 小王, 过来,有你的电话。
(4)表示被动结构“be +under/ in等介词+名词” 结构可替换进行时被动语态。
