20.C drive跟mind是伴随状态,也就是同时发生,用ing形式,如：He sits there,crying.这里的crying也是个伴随状态；when是个非限制从句引导词,引导时间状语.
21.C 这句主要是判断短语意思,in general 总的来说,so far目前,before long不久以后（区分long before,很久以前）,after all毕竟.根据句意应该选择C.
20.C minding ....现在分词做状语，与逻辑主语I 是主动关系；when 表示这是时
21. C before long 不久
in general 一般来说 so far 到目前为止 after all 毕竟
