DO not read very much farther ahead until you understand what is being said
问题描述：
DO not read very much farther ahead until you understand what is being said
为什么最后那个宾语从句what is being said .
said为什么前面还要加一个being呢..如果是被动语态那么有一个is不就可以表示了吗?为什么还要一个being..
答
分析句子,这里的undestand的宾语是what引导的句子,即你看的内容
这里书的内容是被看,所以用被动那么有一个作文上面写了一句The book told。。既然书是被看，那为什么这里书不是被说呢，，，主语在不同情况下不同啊，而The book told……这里是书做主语就像人一样，人可以被告知，sb is told that……也可以告诉别人sb told that……
