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.

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。

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

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 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。
