问题补充：

I won’t see the film tonight. I am busy. , it is raining cats and dogs.

A. somehow

B. however

C. besides

D. as well as

答案：

A. somehow

B. however

(答案→)C. besides

D. as well as

解析：

试题分析:考查插入语。A不知怎么的；B然而；C此外；D除。。以外还。从语境判断，I am busy. 和it is raining cats and dogs是说明不能去看电影的原因，并且前后是递进关系，所以选C。句意：我今晚不去看电影了。我现在很忙，此外，还下着瓢泼大雨。
