keep后面接动词的什么形式?可以接V-ed吗?

不是,接V-ing
keep后接动词时有三种用法：
1.keep sb doing sth保持某人做某事,使某人（一直）做某事.例如：He kept the horse working all day.他让马工作了一天.
2.keep sb from doing sth阻止某人做某事,使某人不做某事.例如：My mother kept me from playing games.妈妈不让我玩游戏.
3.keep sb/sth done使...被...,保持...处于某种状态.keep the eyes closed的意思就是“闭上眼睛,使眼睛闭上”,为什么是被动语态呢?因为eyes和close的关系就是被动关系呀,对不对?
