相信学习英语的朋友们都知道，“stop” 作动词时的意思是 “停止”，它的后面既可以跟动词的 -ing 形式，也可以跟不定式 “to do”。“Stop doing” 和 “stop to do” 的区别是什么？
用法总结
Stop can be followed by an ING verb or a full infinitive verb. This is called a verb pattern. Which form is chosen depends on the speakers meaning.
动词 “stop” 后可跟动词-ing 形式，即 “doing”，或不定式 “to do”。这被称作动词模式（verb pattern）。具体应使用哪个动词模式要根据说话者的意思而定。
1. Stop + ING verb
Stop doing = 停止做某事
When stop is followed by an ING verb, it is the activity in the ING verb which is stopped.
当动词 “stop” 后跟动词-ing 时，动词-ing 描述的是要被停止的动作。
- John has finally stopped smoking. You won't see him doing it any more.
- After about an hour, they stopped playing football and rested.
- She's stopped making that mistake now and her language is much better.
2. Stop + full infinitive verb
Stop to do = 停下来去做某事
When stop is followed by a full infinitive verb, it is another action which stops. The action in the full infinitive is the reason why.
当动词 “stop” 后跟不定式 “to do” 时，这表示要停下正在做的动作，去做另一个动作。“Stop to” 后接的动词是要去做的动作。
- I was watching TV but I stopped to do some homework.
- After about an hour of playing football, they stopped to rest.
- I had to stop to change a tyre. One of mine had been punctured.
