There is going to be two football matches the day after tomo

整句都要改啊
There are going to be two football matches the day after tomorrow,aren't there?
there be句型的一般将来时态有两种,分别对应的反意疑问句是:
1.There will be.,won't there?
2.There is/are going to be...,isn't/aren't there?
尤其是第2句,is/are的选择和第二个be(to后面只能用动词原形be)的第一个名词短语的性质(可不可数)和单复数保持一致.

are 因为be 动词的变化是看名词主语，主语是football matches是复数要用are，后面的要用aren't.

is 代指前面这句话
