when引导的状语从句的动作多为终止性动词， 也为可持续动词；但while只能是可持续动词。
（1） while, when, as 这三个连词都可引导时间状语从句，但用法有所不同。 1) 当某事正在进行的时候，又发生了另一件事。While, when, as 都可用来引导表示“背景”的时间状语从句。 例如：
As/When/While I was walking down the street I noticed a police car. 2) 当两个长动作同时进行的时候，最常用的是while。 例如：
While mother was cooking lunch, I was doing my homework. 3) 当两个动作都表示发展变化的情况时，最常用的是as。 例如：

have a rest.
(这里，when引导的时间状语从句中用现在完成时表示将来要完成的 一个动作，这个动作比主句的动作先发生。)
3．表示“随着……”，连词用as，不用when或while。 如：
As the election approached, the violence got worse.
or(或者，否则), otherwise(否则), or else(否则), either...or(不是……就是)
but(但是，可是，只是因为), yet(可是), not…but…(不是……而是……)
4．如果主句表示的是短暂动作，而从句用延续性 动作的进行时态表示在一段时间内正在进行的动 作时，when, while与as 可互换使用。如：
When/While/As I was walking down the street, I came across an old friend of mine.
heard the doorbell ring.
When I stopped my car, a man came up to me. (不可用while) 2．从句动作发生在主句动作之前时，只能用when引 导这个从句，不可用as或while。如：
When you have finished your work, you may
they actually are. (湖南)
解题关键
把握前后分句的逻辑关系是解题关键： 并列连词的考察主要是通过句子意义及 两个并列成分之间的关系来判断连词词 义，解题时准确理解题干的意义，理清 前后逻辑关系很重要。

概念
连词是一种虚词,它不能独立地担任句子成分,只是连接词与词、短语与短语以及句子与句子的作用。 英语中连词只要分两类：并列与从属连词。
并列连词：用来连接平行的词、短语或分句。
从属连词：用来引导一个从句。
并列连词连接两个分句，构成并列句。
Observe the following sentences. till /until They played volleyball until (till) it got dark. They didn’t talk until (till) the interpreter came. He didn’t go to bed until (till) his father came back.
