be busy doing sth
I’m busy cooking (the) dinner. 我正忙着烧饭。
She was busy weeding the garden. 她在花园里忙着除草。
请问这样用的 doing 是现在分词还是动名词?
be busy doing sth 中的 doing sth 是现在分词:
I’m busy cooking (the) dinner. 我正忙着烧饭。
She was busy weeding the garden. 她在花园里忙着除草。
若在 doing 前面使用了介词 with / in,则 doing 为动名词:
I’m busy in / with cooking (the) dinner. 我正忙着烧饭。
She was busy in / with weeding the garden. 她在花园里忙着除草。
