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。 |
