be occupied with和be engaged with的區別和用法?

題目：

be occupied with和be engaged with的區別和用法?
兩個都有忙於做的意思，求區別

解答：

據我所知,一般來說,用be engaged in （sth/doing sth）表示「從事,忙於」的意思.
be engaged with 也有「忙於」的意思,但一般表示與某人正在談什麼事；有約；與…洽談；和…交戰；忙於…
如：I'll be engaged with a client this evening.
我晚上和一個客戶有事.
雖然,be occupied in和 be engaged in 都表示「忙於...」,但前者有被迫地忙於做某事的意思,比較被動.後者著重於主動地忙於做某事.
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.
他從事於新產品系列包裝的研究.
另外,get/be engaged to sb.與某人訂婚
