现在进行时态的被动语态的肯定式为：am/is/are + being + done。如：

The question is being discussed at the meeting now. 这个问题现在正在会上被讨论。

二、现在进行时的被动语态的主要用法：

1. 现在进行时的被动语态同它的主动语态一样，表示现在正在进行的被动动作。如：

2. 现在进行时的被动语态同它的主动语态一样，表示现阶段正在进行的被动动作。如：

三、特别提醒：

The problem is under discussion （is being discussed） at the meeting. 这个问题正在会上被讨论。

The telephone is in use （is being used） now. 这部电话正在使用中。
