本回答被网友采纳stop from，keep from和prevent from 都是“阻止……做……”的意思
它们可以互换。它们的区别不大，如：
prevent sb from doing sth阻止某人做某事,让某人不做某事
stop sb from doing sth让某人不做某事
keep
sb from doing sth让某人不做某事(保持不做某事,有个持续动作)
用法上的差别：在主动式中,stop sb.from doing
sth.和prevent sb.from doing sth.中的介词from可以省略,但 keep sb.from doing
sth.中的介词from不能省略（keep sb.doing sth.意思为让某人一直做某事）.
在被动式中三个词组中的from都不能省.
如
We should stop / prevent / keep the children from playing with fire.
我们应该阻止孩子玩火。
