we are busy with the work while they are asleep on the ground.为什么不用when呢
when和while的用法有什么区别呢

while这儿是并列连词,用作转折对比,意为“而”.句意：我们忙于工作而他们在地上睡觉.再如：I like English while he likes Chinese.（我喜欢英语而她喜欢汉语）.when没有这种用法.

我们忙于工作而他们却在地上睡觉。
这里是“可是、却”的意思。

强调 同时 进行 用while

while 是正当、正在的 意思 when 是当
不是we are busy with the work 是we are busy with work

这里是while的一种特殊用法，表示两方面的对比，有点转折意味，是并列关系，例如：
He loves playing soccer while she loves playing basketball.

when是瞬时的动作，他们在睡觉是延续性的用while，

while有对比的意思。也可以翻译成 然而
我们忙着工作时，他们却躺在草地上呼呼大睡...

while是“与此同时”，when是“当···时”，这里如果使用when就应该使用动词的-ing形式

很好区分的，区别就是when是短暂性的，while是延续性的。句中的情况是延续状态，因为不仅是“忙”，还是"睡着"都是一个延续性的动作，所以用“while”不用“when”
