1、My friends are busy preparing my birthday party.我的朋友們正忙于準(zhǔn)備我的生日宴會(huì)。
2、后面接名詞時(shí)可以將doing換成介詞with,即be busy doing sth = be busy with sth.也可以說(shuō)成My friends are busy with my birthday party. busy的兩個(gè)短語(yǔ)是:be busy with +名詞。
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. (幫你結(jié)合了一下) O(∩_∩)O~be busy in doing sth ,后面是加“動(dòng)詞ing ”形式,in 可以省去。
5、be busy with sth ,后面直接加“名詞”。
6、意為某人忙于做某事。
7、eg:I am busy doing homework.(我忙于做作業(yè))。
