问题描述:

It is very important that all the birds are stopped from being killed.stopped & killed的用法?

这是一个形式主语句型,真正的主语是
all the birds are stopped from being killed.
而这个主语从句的主语是all the birds,be+PP被动式作谓语,being killed是被杀,所以用kill的过去分词形式,在介词from之后做宾语。

stopped 是主语从句的谓语部分,表示被动
killed是作from 后面的动名词被动结构,跟being killed一起充当from 的宾语

are stopped (谓语动词,被动语态)
from being killed (介词后面的被动语态)
