1、表示现阶段正在进行的动作 ?现在进行时被动语态也可表示目前这一阶段主语正在承受谓语动词的动作。例: Rainforests?are?being?cut?and?burned?at ?such?a?speed?that?they?will?disappear?from?the?earth?in?the?near?future.?

下面将唱一首民歌。 A?party?is?being?held?tonight.?
今晚将要举行一场晚会。 It?is?said?that?a?plane?is?being?flown?by?him?to?America?at?eight?next?Sunday?morning.?
