books of this kind ----well A sell B sells C were sold D is sold

问题描述:

books of this kind ----well A sell B sells C were sold D is sold
什么时候用被动语态的卖得好?、什么时候不用?

当强调动作时 Books of this kind are sold by me.
强调状态时 Books of this kind sell well.这类的书使用单数吧???主语是books, of this kind 是做定语用的译为 “这类的书” 关键词是“书”,即主语
