be busy后接不定式还是现在分词

be busy后习惯上要接现在分词,不能接不定式。如:

She’s busy writing letters. 她正忙着写信呢。

She was busy preparing lessons. 她忙于备课。

He was busy packing, for he was leaving that night. 他那时正忙着打点行李,因为那天晚上他就要走了。

顺便说一句,busy用作动词时,通常用于busy oneself doing sth,其中的现在分词也不能换成不定式。如:

He busied himself cooking the dinner. 他忙着做饭。

She busied herself tidying up her desk. 她忙着收拾她的写字台。

注:有时可在现在分词前加上介词in,这样一来现在分词就变成了动名词。如:

She was busy in preparing lessons. 她忙于备课。

He busied himself in cooking the dinner. 他忙着做饭。
