Question

In classes,you'd better understand as much as possible while (taking) notes.关于while的用法
while不是引导从句吗?为什么while taking notes 这句没有动词?

Answer 1

该句子是时间状语从句,其实句子有省略成分,还原就是：
In classes,you'd better understand as much as possible while u're talking notes.
当从句和主句的主语一致时,且从句是主语加be动词时,从句的主语和be动词可以省略.这个句子就是这种情况.
意思是课堂上,在做笔记的同时,你也要尽可能的听懂老师讲的.
while u're talking notes. 现在进行时,强调动作正在进行.take就是动词.其他例子：
while young, she was interested in math. (省略了从句的主语和be动词）
while she was young, she was interested in math
不明白的可以再问,希望帮的上你
