I learn while listening to musie为什么要用ding？

Question

如题所述

Answer 1

I learn while listening to music.
翻译，我边听音乐边学习。
while后面本来是一个状语从句，省略成了非谓语，因为主语是I。不省略的话是：
while I am listening。
while，conj. 在……期间；在……的过程中；与……同时。例如：
I had a cigarette while I was waiting.
我等候时抽了一支烟。
可以省略成：I had a cigarette while waiting.
