据我所知,一般来说,用be engaged in (sth/doing sth)表示“从事,忙于”的意思。
be engaged with 也有“忙于”的意思,但一般表示与某人正在谈什么事;有约;与…洽谈;和…交战;忙于…
如:I'll be engaged with a client this evening.
我晚上和一个客户有事。
虽然,be occupied in和 be engaged in 都表示“忙于...”,但前者有被迫地忙于做某事的意思,比较被动。后者着重于主动地忙于做某事。
例句:
I'm fully occupied with my office work and have little time for housework.
He be engaged in research into the packaging of the new product line.
他从事于新产品系列包装的研究。
另外,get/be engaged to sb.与某人订婚
追问occupied with呢
