1、My friends are busy preparing my birthday party.我的朋友们正忙于准备我的生日宴会。

2、后面接名词时可以将doing换成介词with,即be busy doing sth = be busy with sth.也可以说成My friends are busy with my birthday party. busy的两个短语是：be busy with +名词。

3、如：I am busy with my homework. be busy doing(in), in 可以省略。

4、如 I am busydoing (in) my homework. （帮你结合了一下） O(∩_∩)O~be busy in doing sth ,后面是加“动词ing ”形式，in 可以省去。

5、be busy with sth ，后面直接加“名词”。

6、意为某人忙于做某事。

7、eg：I am busy doing homework.（我忙于做作业）。
