There are 19 students go to school by bus.对吗?必须用going吗!

题目

There are 19 students go to school by bus.对吗?必须用going吗!
There is a dog sleeping under a tree.绝对要用doing.可这个句子不是现在进行时,也不是将来时啊!

答案

应该是：There are 19 students going to school by bus.也可以写为：There are 19 students who go to school by bus.（这是定语从句）如果同时用are和go会让句子有两个谓语,所以go要变为going,这时going不一定要表...
