高考英语特殊词精讲及典型例题

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 smoking.　　　　　 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。

2 forget doing/to do

forget to do　忘记要去做某事。　(未做)forget doing　忘记做过某事。　　(已做)The light in the office is stil on. He forgot to turn it off.办公室的灯还在亮着，它忘记关了。(没有做关灯的动作)He forgot turning the light off. 他忘记他已经关了灯了。　　　 ( 已做过关灯的动作)Don't forget to come tomorrow.别忘了明天来。　　　　　　　　 (to come动作未做)典型例题---- The light in the office is still on.---- Oh，I forgot___.　　　　　　　　　　A. turning it off　 B. turn it off　 C. to turn it off　 D. having turned it off答案：C。由the light is still on 可知灯亮着，即关灯的动作没有发生，因此用forget to do sth.而forget doing sth表示灯已经关上了，而自己忘记了这一事实。此处不符合题意。

3 remember doing/to do
	remember to do 记得去做某事　　　　 (未做)remember doing　记得做过某事　　　 (已做)Remember to go to the post office after school.记着放学后去趟邮局。Don't you remember seeing the man before? 你不记得以前见过那个人吗?
