1.Adverbial Clauses of Time:（时间状语从句） Different Kinds of Adverbial Clauses:

When I heard the news,I jumped with joy.
I owed Jack 100yuan when I was in london. I.when/while/as 的区别
While I was reading,he came in.
I made some friends while I was in london As time goes by, he knows a lot. The students sang as they walked. 时间状语从句 when, while, as
三者的具体用法关键在于动作发生的时间及从句的动词。while 表时间，从句需用延续性动词，不用瞬间动词；when 表时间，从句既可用延续性动词，又可以用瞬间动词；as 表时间，与when 相似，但侧重强调主、从句动作同点或同段进行，可用延续行动词的一般过去式表式过去进行时。when, while 后还可以接分词短语。when 作并列连词，表示一个动作在发生时，另一个动作接着发生，这时就不能用while、as。 I was walking on the street when suddenly someone patted me on the shoulder.
while 作并列连词，表示两种情况对比。 He was playing the guitar while his sister was watching TV.
