Using before, after, when and while 时间状语从句是指在复合句中充当时间状语的句子。 before意思是“在……之前”，表示主句动作发生在从句动作之前。 Close the windows before you leave the room, please.在你离开房间前，请关上窗。 after意思是“在……之后”，表示主句的动作发生在从句的动作之后。 I went to school after I finished my breakfast.我吃完早饭后去上学。 when意思是“当……时”，表示主句动作发生的特定时间。 While my sister was sweeping the floor, I was washing the dishes.我姐姐扫地时，我在洗碗。 while意思是“当……时”，强调主句动作和从句动作是同时发生的。 The days get longer when spring comes.春天来时，白天变长了。 注意：while引导的从句的谓语动词必须是延续性的。 注意：before和after也可以作为时间介词。如： before 9 a.m. after lunch since, till和until常用来引导时间状语从句。如： Mr Brown has been in Beijing since you left. 自从你离开，布朗先生就一直待在北京。 I worked till/until he came back. 我一直工作到他回来为止。 since,till和until 引导的时间状语从句 I go jogging every morning.

You 've been happy since I first met you. since means ________ a certain time. from till和until意思是 “到……为止” ，一般情况下两者可以互换。until可以放在句首或句中，而till不可以用在句首。 注意：如果主句中的谓语动词是瞬时动词时，必须用否定形式，即“not…until”结构，意思是“直到……才（开始）”，此时until不能替换为till如： Walk till/until you see a white house. 一直走到你看到一座白房子为止。 I did not go to bed until I finished my homework. 直到做完作业我才上床睡觉。 as soon as和whenever引导的时间状语从句 我们常用as soon as和whenever引导时间状语从句。如： As soon as I arrive in Canada, I will call you. 我一到加拿大，就给你打电话。 Whenever he met us, he smiled at us. 他每次遇见我们，都向我们微笑。 as soon as意思是“一……就”。如： We began to work as soon as we got there. 我们一到那里就开始工作。 He will visit you as soon as he gets there。 他一到那里就会去拜访你。 whenever意思是“每当；任何时候”。如： He likes listening to music whenever he has time. 每当他有时间的时候，他喜欢听音乐。 注意：whenever可以用every time替换。 as soon as和whenever 引导的时间状语从句 我们常用as soon as和whenever引导时间状语从句。如 As soon as I arrive in Canada, I will call you. 我一到加拿大，就给你打电话。 Whenever he met us, he smiled at us. 他每次遇见我们，都向我们微笑。 since + 过去的时间点 /动作 主句： 现在完成时 Mr Brown has been in Beijing since you left.
