When my shoulder was better, I had to work hard to get back into shape. After I got well, I trained for four years and finally made my dream come true! My coach was proud of me. He was sure about my success before the accident happened. And he never gave up on me even during the most difficult times. What kind of clause are they? 这些句子都表达某事情/行为发生的时间，叫作时间状语从句(adverbial clause of time)。 时间状语从句可以放在主句之前，也可放在主句之后。 我们常用when, while, before, after来引导时间状语从句。 When I was a child, my dream was to become an Olympic swimmer. One day, while I was training, I hurt my shoulder. I had to get months of treatment. When my shoulder was better, I had to work hard to get back into shape. After I got well, I trained for four years and finally made my dream come true! My coach was proud of me. He was sure about my success before the accident happened.

A Using before, after, when and while Grammar focus ① When she was very young, she could play the piano. ② When the bell rang, he reached for it. when意思是“当……时”，表示主句发生的特定时间。既可以表示在某一时间点发生的事，又可以表示在某一时间段发生的事。 注意：when引导的从句的谓语动词可以是延续性的，也可以是瞬时性的。 1. when引导的时间状语从句 在她很小的时候，她就会弹钢琴了。 电话铃响，他伸手去接。 While she was cooking dinner, her phone rang. While my sister was sweeping the floor, I was washing the dishes. 2. while引导的时间状语从句 while意思是“当……时”，强调主句动作是和从句动作同时发生的。 注意：while引导的从句的谓语动词必须是延续性的。 while还可以表示“在……期间”，表示主句动作发生在从句动作进行的过程中。 她在做晚饭的时候，电话响了。 我姐姐扫地时，我在洗碗。 在when和while引导的从句中，当主句和从句的主语一致，并且从句中有be动词时，从句可以省略主语和be动词，构成“when/while+ 动词-ing/介词短语”结构。 ① When (she was) in trouble, she always ask for my help. ② While (I am) travelling, I like to buy some souvenirs. 她遇到困难时，总是向我求助。 旅游时我喜欢买纪念品。 before意为“在……之前”，表示主句动作发生在从句动作之前。 ① Close the windows before you leave the room, please. ② Before we start our lesson, let’s read the words. 3. before引导的时间状语从句 在你离开房间前，请关上窗。 上课之前，我们先读单词。 after意为“在……之后”，表示主句动作发生在从句动作之后。 ① I went to school after I finished my breakfast. ② After I get up, I wash my face. 4. after引导的时间状语从句 我吃完早饭去上学。 我起床后洗脸。 Practice Simon is writing a blog post about his uncle.

Many questions about the universe were too difficult for common people to understand until Hawking wrote his books. Read the text and answer the questions. 1 2 3 Hawking’s books help common people understand difficult questions about the universe. 我们也可以用since, till, until来引导时间状语从句。 Since I learnt about the amazing stories of Stephen Hawking, I have often thought of him when I face challenges.

Match the conjunctions with the proper meanings. a. up to a certain time b. from a certain time b a a We can use since, till and until ______ (at the start or in the middle, only at the start) of a sentence. B Using since, till and until Grammar focus ① They have been friends since they were at primary school. ② I have known Bill since he was born. since意为“自从……以来”。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。 注意：since引导的从句的谓语动词可以是延续性动词，也可以是瞬时动词。 1. since引导的时间状语从句 他们从小学起就一直是好朋友。 从比尔出生起，我就认识他。 ① I slept until / till my father came back. ② Until I came, they were reading newspapers. 2. till/until引导的时间状语从句 • till和until意思是 “到……为止” ，一般情况下两者可以互换，但till不如until正式。 • until可以放在句首或句中，而till一般不放在句首。 注意：till/until用在肯定句中时，表示主句的动作或状态一直持续到从句动作发生或状态出现时为止，因此主句的谓语动词必须是可延续性的。 我一直睡到爸爸回来。 直到我到了，他们还在读报纸。 ① We did not get off the bus till/until it stopped. ② We didn't realize the importance of English till/until we left school. 如果主句中的谓语动词是瞬时动词，该动词用否定形式，即“not... till/until”结构，意思是“直到……才（开始）”，表示主句的动作在从句的动作发生之后才开始。 直到车停了，我们才下了公交车。 我们直到离开学校才意识到英语的重要性。 Practice Sandy and Simon are talking about their dreams.
