Question

there+is+a+big+zoo+near+the+school改为一般疑问句

Answer 1

There is a big zoo near the school.学校附近有一个大动物园。
这是一个there be （有）句型的句子，它的一般疑问句只需要把be动词提到 there前，再在句尾加上个问号。即写成：
Is there a big zoo near the school? 学校附近有一个大动物园吗？

Answer 2

Is there a big zoo near the school？
there is 的否定句为：there isn't...；一般疑问句为：Is there...？
