因为 stop sb. (from) doing sth 和 prevent sb (from) doing sth 省掉了from 不会影响语义,而 keep sb. from doing sth 省掉from后,意思正好相反:
I kept him working on his homework —— 我一直让他做作业
I kept him from working on his homework —— 我不让他做作业

网友(2):

keep后面from省略后就变成另外一个意思,只有在keep from doing sth 时才有阻止做某事的意思,而keep doing sth 就是一直做某事的意思,所以keep后面from不可省略。

网友(3):

因为如果keep sb from doing sth......省掉之后变成keep sb doing sth意思变为“使某人一直做某事”。所以不能省

网友(4):

keep doing 表示一直在做,加了from 才能表示prevent的意思
