some ads on losing weight have been banned from being broadcast on TV
问题描述：
some ads on losing weight have been banned from being broadcast on TV
一些减肥广告已经在电视上停播了
被动是用在被禁止上 have been banned
为什么后面是being broadcast?而不是 have been banned from broadcasting?
答
have been banned 是已经被禁止,be broadcast是被播放啊.难道广告自己会播放?而用being,是因为介词from后面要接名词,而be是动词,所以要变形为动名词形态.
