1.The students took notes as they listened carefully.
2.John sings as he works.
3.She was singing while I was dancing.
4.Meimei watched TV while she ate her supper.
我的疑问是:
as所在句子的主从句的主语是否要相同?
as所在句的延续性动词为什么不用be doing?
第4句对吗?为什么不用be doing? while可以换as吗?
表达"一边...一边..."时,as与while的区别?
谢谢!

以上四句都正确。
我的疑问是:
as所在句子的主从句的主语是否要相同?(可以不同)
as所在句的延续性动词为什么不用be doing? (只要两个动作延续就行,可以不用进行体)
第4句对吗?为什么不用be doing? while可以换as吗?(正确。可以不用进行体,可以换成 as)
表达"一边...一边..."时,as与while的区别?(几乎没有区别。但as 更强调两个动作的同时进行。)
