what made Bill so angry?_____His girl friend promised to come at 8:30,but she hasn't come yet. A Having kept waiting B Being kept waiting
为什么选B不选A?

Answer 1

。。。His girl friend promised to come at 8:30,but she hasn't come yet.
回答应是Bill was keep waiting or Bill kept waiting，都是持续的，而A和B都没有主语Bill,动词作主语加-ing,再加上Bill的等待是一直延续的，是一种状态，A是现在完成时，有时间断点，表现的是已经完成的动作，与要求不符。而B是be动词作主语，加ing,符合题目，所以选B不选A。

Answer 2

可以用另外一个句子来解释,会更明了：what made Bill so angry?Because his girl friend promised to come at 8:30,but she hasen't come yet,it was that she had kept Bill waiting made Bill so angry.
你不能说Bill kept himself waiting,而应该是“被”“保持等待的状态”,所以应该用被动的语态，即Bill was kept waiting,后面的句子省略了主语，所以应该用Being kept waiting

Answer 3

因为B答案代表一种状态，就是他女朋友承诺8:30来这件事，状态一直持续。选A逻辑不通，语法也错误
