eg: There existed roaches in ancient times.(古代有蟑螂)这句话是there be 句型吗?是的话be哪去了?
there be 句型中be可以变为was were 也可以变为be going to和have been 形式吗?如果是的话,为我分析下下面两句话
eg:There is going to be a meeting tonight.(这里面感觉是现在进行时插入在there be中间而非be变为be going to .)
eg:There have been a big tree on the top of the hill.(这里面又觉得be直接变成了has been而非插入)
求解!!!!!!!!!!
谢谢!There is going to be a meeting tonight.在这个句子中be是哪个?是 is going to 还是它之后的be?

追答是is going to 后面的那个原型be,is going to整体表将来时
