8、 a. 表示时态，例如：He is singing.他在唱歌。He has got married.他已结婚。 b. 表示语态，例如：He was sent to England.他被派往英国。 c. 构成疑问句，例如：Do you like college life?你喜欢大学生活吗？Did you study English before you came here?你来这儿之前学过英语吗？ d. 与否定副词not合用，构成否定句，例如：I dont like him. 我不喜欢他。 e. 加强语气，例如：Do come to the party tomorrow evening. 明天晚

10、忘记他已经关了灯了。 ( 已做过关灯的动作)Dont 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
