1.

构成：am/is/are (not) + being + V-过去分词

2.

意义：…正在被做.表示说话时或现阶段正在进行的被动动作,强调主语是承受者。

3. 用法

1. 表现正在进行或发生的被动动作，常与now, look等词连用。

e.g.

She is being examined by the doctor now.

Look! The children are being taken care of by their aunt.

2. 表示现阶段或目前这段时间正在进行的被动动作，但这一被动动作在此时此刻不一定正在发生。

e.g.

A new factory is being built. They are being taught English at present. 3. 表示一种经常性或习惯性的被动行为，常与always, forever, continually, constantly等词连用，往往带有赞扬、责备、厌烦及埋怨等感情色彩。

e.g. Tom is always being praised by the teacher.

4. 与情态动词连用，表示对现在正在发生的被动行为的推测。

e.g. (1) John is not here. He must be being interviewed

(2) ---Do you know what Smith is doing ?

---He is ill. He may be being examined by the doctor.

5. be + under / in +n. 的结构可以表示现在进行时的被动语态的含义。

The problem is under discussion now.

= The problem is being discussed now. The telephone is in use. = The telephone is being used. “be +under/in+名词”结构可表示现在进行时的被动语态的含义。

under discussion 正在被讨论

under examination 正在被检查

under protection 正在被保护

under repair正在被修理
