问题描述:

--Why are you excited?--Because there__an exam tonight.A will have B.is going to have C will be
为什么?要理由= =

这是 there be 句型的 一般将来时的用法,就是 there will be ...
如:There will be a letter for you tomorrow.明天将会有你一封信.那如果有一个选项是 is going to be这个选项的话也是对的么??谢谢~这个是这样的,如果有一个是,而且不能为人所控制的,用 be going to do sth如 It's going to rain.;另外,表达人的一种意愿,意欲做某事,但是还没有做,也许不发生,也可以用 be be going to do sth 。但是will be 就一定会发生,是已经定了的事情。我的理解就是这样。
