英语关于连词、从句的问题
以前老师告诉我while前后的句子时态都要是ing,也就是进行时,但是我有时候看见由while连接的前后两个句子不一定都是进行时,有时候还都不是进行时,为什么?还有when引导的从句,我一直是以为when连接的前后句子时态必须一致,但是好像不是这样啊.请高手系统的给我讲一下各个连词的用法,还有as这个词我一直不知道怎么用,请不要复制粘贴一些我看不懂的东西,

while 引导时间状语从句的时候,一般是这样的,比如：
While John was watching TV, his wife was cooking.
I got home while dad was reading newspaper.
担不全部是.比如：
While he was a young boy, he was always ready to help others.
Will you watch my clothes while I have a swim.
在 while 引导让步从句的时候,不一定用现在进行时：
I like playing football while you like playing basketball.
上面是比较明显的.你有兴趣的话,到下面链接看看吧：
