stop from,keep from和prevent from的区别
stop sb. from doing sth./ prevent sb. from doing sth./ keep sb. from doing sth.三者都表示“阻止某人做某事”, 一般情况下可以通用。如果一定要找出意思上细微差别,如下: 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。
