A. to have restedB. resting C. to restD. rest 答案:C。由题意可知,她到了山顶,
2、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。 8.2 forget doing/to do forget to do忘记要去做某事,forget doing忘记做过某事。例如: The light in the office is stil on.

3、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,而忘记了这一事实。此处不符合题意。 8.3 remember doing/to do remember to do 记得去做某事,remember doing记得
4、做过某事。例如: Remember to go to the post office after school. 记着放学后去趟邮局。 Dont you remember seeing the man before? 你不记得以前见过那个人吗? 8.4 regret doing/to do regret to do对将要做的事遗憾,regret doing对做过的事遗憾、后悔。例如: I regret to have to do this, but I have no choice. 我很遗憾必须这样去做,我实在没有办法。 I dont regret telling her what I th
