when 和 while的主要区别在于:

1. when 可以引导到“特殊疑问句”和“名词性从句”(主语从句、宾语从句、表语从句、同位语从句);while 不可以,它没有这个功能。例如,网友的问题,就是一个“特殊疑问句”。只能用when 提问,不能用while。例如:

When did you begin to study French? (正)

I began to study French when I was seven.

决不能说:

While did you begin to study French? (误)

I began to study French when I was seven.

关于“名词性从句”,只能用when 引导,不能用while。因为“名词性从句”原本就是一个“特殊疑问句”。例如下面的宾语从句:

I don't know when they will start off. (正)

I don't know while they will start off. (误)

2. when 和 while 都是“从属连词”,都可以引导“时间状语从句”。

when 可以表示“时间点”(跟终止性动词连用), 也可以表示“时间段”(跟延续性动词连用)。而while 只能表示“时间段”(跟延续性动词连用),此时,while 跟when 可以互换使用。举例如下:

The train had left when I arrived at the station. (正)

The train had left while I arrived at the station. (误)

He found a wallet when he was walking in the street. (正)

He found a wallet while he was walking in the street. (正)
