(was reading是延续性的动词，was reading和was watching同时发生) 并且while有时还可以表示对比。(然而)I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。 （对比） as表示“一边一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生。We always sing as we walk.我们总是边走边唱。（as表示“一边一边”）as也可以强调“一先一后”。As we were going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间） 补充as的用法：as除了“当时候”，“一边一边”外还有以下用法：1. as介词，“作为”As a student, we should focus on study.2. as连词，“因为”As he has much homework to do, he has no time for hobbies.3. as as 与一样 / such as比如4. as soon as 一就As soon as he gets to Beijing he will call you.5. 连词“按照”，“如同”，“与一样”You must do everything as I told you.I will be a teacher as you are.随堂练习：1. 完成下列句子：(1) 我父亲在看电视时睡着了。My father fell asleep _he was reading the newspaper. while/as(2) 妈妈做饭的时候,我在做作业。_ Mum was cooking dinner, I was doing my homework.
