but和while的用法区别

but和while的用法区别为:but意在强调后者,while强调的是两者同时发生。

but作连词表示“但是”,作介词表示“除了”。while作连词表示“当……的时候”,作名词表示“一会”;while强调的是两者同时发生。

but意在强调后者;while强调对比,but强调转折,表示完全的转折。当while作为连接词引出转折的时候作用和but是一样的。除了转折,while还可以表示当……时。

只有当连接两个独立主句时连接词前才加逗号。

but后面提到的通常是一些“新”的东西,并且和前面的内容形成强烈对比。

while作“然而、但是”理解时,更偏向于相反的情况,前后半句说的往往是同一件事。

while的语气相比but更委婉,可以放在句中也可以放在句首。

but通常只会放在句中,放在句首时表示惊讶、震惊等较为激烈的情绪。
