——Will Thursday or Friday suit you ?

——Either will do


這里的suit可以換為fit么？它們有什麽區別啊？適用條件一樣么?

先謝謝了哈！

suit: 1.指衣服的款式花色、发型适合某人。2.对某人方便。
fit: 指衣服的尺码大小。
the seven o'clock train will suit us very well.
will Thursday suit you.
Do you think this style suits me?
Red and black are colours that suit me very well.
可见，suit 和fit 在这个句子中不可替换。

续上文
fit 一般指尺寸大小.
these shoes don't fit me.
the cooker won't fit in your new kitchen.

啊~是这么回事啊！谢谢啦！
