Isthereariverintheforest肯定句？

Question

改

Answer 1

there be 句型表示存在、有的含义。进行语法变形时，把be动词提到句首就可以把原句由陈述句变为一般疑问句，反之就可以得到陈述句。

There is a river in the forest. 森林里有一条小河。

Answer 2

There is a river in the forest.

森林中有一条河。

注
一般疑问句变陈述句，句子中有be动词，情态动词时直接把这些词放回主语后

Answer 3

Is there a river in the forest？
这个英语句子改为肯定句如下：
There is a river in the forest.
森林里有一条河。

Answer 4

there is a river in the forest.
