示“就在那时”。

in the countryside, I used to carry some water for
him.

while引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或
者相
对应）。
While my wife was reading the newspaper,
I was watching TV.
(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
