题目

I ___ for Beijing tonight for there is _ an important meeting .
I _ for Beijing tonight for there is ___ an important meeting .
A.am leaving;to be B.leave;to be C.am leaving;to have D.will leave;to have
请解释为什么

答案

题意是说：今晚我将离开去北京,因为有一场重要会议.
由于是今晚去,显然此时说话人要用进行时表将来或者用情态动词will,排除B选项；又由于表示将有什么的语句是there is to be 或者there is going to be ,没有there is to have 这种表示法.故选A
