Question

the childent are going to have a picnic 中的there is going to have

不是没有There is going to have的说发吗？

Answer 1

你可能是误会了，在the childent are going to have a picnic句中，并没有出现
there is going to have的句式，没有there，所以并不矛盾。
如果句子是比如说there is going to have a pincic，这样的话就是不对的。
希望对你有所帮助！

Answer 2

主语 be going to 动词原形
The childent are going to have a picnic。
这是对的。

There is/are going to be（存在有的将来时）

Answer 3

确实没有there is going to have这种说法，但是你的例句是
children做主语，没问题啊。

Answer 4

the childent are going to have a picnic
哪有there？

Answer 5

是的
There is going to do something不能与have连用，两者均为 有 的意思
