最好不替换,work on说的是你正在做的是什么,不涉及是否着急做
而be busy doing以为着你正在忙着做某事,而且事情比较急迫

意思差不太多，前者有突出忙这一点，后者就是单纯的说在干什么
忙于做…… 在做……

不能
忙于做某事be busy doing sth
从事于work on

不能，前者是忙于做某事，而后者是从事什么，很容易区别的啊

可以替换
如 He is busy doing his homework。==He is working on his homework。他正忙着做作业。
be busy doing sth忙于做某事
work on致力于…
He has been working on a new novel for over a year now.
近一年多来, 他一直在写一部新小说。
