There is going to be ,还是 There are going to be?

题目

There is going to be ,还是 There are going to be?
我们老师讲过：There is going to be 2 tests .而且强调不管是单还是复都要用is,而我在教辅书上看到There are going to be two football matches at our school next week .于是我就纠结了,到底是一定要用is,还是有单复变化,求真相!

答案

There is/are going to be...中,is/are going to类似将来时的助动词（类似there will be）,也是要和句子的主语保持一致的,你在教辅书上看到的是对的.
