1. the air up there，t和there？
There isn't和there is no都属于There be句型的否定句。二者区别如下:
1，There isn't不能直接接名词。因为not是副词，不是用来修饰名词的。
而There is no可以直接接名词。因为no是形容词，可以修饰名词。如，
There isn't any money left.
There is no money left.
没钱了。
2，no=not any ，所以 There is no =There is not。
比如，There is no water=There is not any water.
没有水。
