You must try your best to stop him____(make) the same mistake again.

问题描述:

You must try your best to stop him____(make) the same mistake again.

making
stop sb (from) doing 这是一个固定搭配,防止某人做某事

You must try your best to stop him_making___(make) the same mistake again.

阻止某人做某事 stop sb doing sth

making

making
stop sb to do 是阻止某人手上的工作去做后面提的工作
stop sb doing是停止某人做某事

一看大家的回答,我郁闷,
我想用to make的,
因为stop to do 是阻止将要做的事,
stop doing是阻止正在做的事
此举后面是the same mistake again,说明是还没再次犯错,所以是还没发生.
