问一道新概念英语上面的选择题目 来帮下忙吧
（ ）at what had happened,Tom didn't know what to do.
A surprising B being surprised C having been surprising B surprised
答
ing表示现在时,和后面的didnt不符,排除A
being+v.表示先后关系,而且还是现在时,排除B
having been ing 没有这种搭配,可以用having been ed
ed 表示过去如何如何,而且动作没有逻辑先后关系,故选D
用手码字不容易,分给我吧,么么哒~being+v.表示先后关系，而且还是现在时，排除B额，能举个例子吗？谢谢了beng asked, i really dont know what to say
