【简明语法】8.1 特殊词精讲－stop doing/to do

stop to do　停止，中断做某事后去做另一件事。
stop doing　停止做某事。
　　They stop to smoke a cigarette.　 他们停下来，抽了根烟。
　　I must stop smoking¹.　　　　　 我必须戒烟了。

典型例题
　 She reached the top of the hill and stopped ___　on a big rock by the side of the path.　
A. to have rested　B. resting　 C. to rest　D. rest
答案：C。由题意可知，她到了山顶，停下来在一个路边的大石头上休息。因此，应选择"stop to do sth. 停下来去做另一件事"。而不仅仅是爬山动作的终止，所以stop doing sth.不正确。

1 smoking   

n.吸烟，抽烟；冒烟

参考例句：

• He was wise to give up smoking.他戒烟是明智的。
• He has decided to cut out smoking and drinking.他已决心戒烟、戒酒。
