there be句型的否定形式则直接在be或助动词、情态动词后加not。例如，There isn’t a box in the room.

否定形式

There be句型的否定句构成方式是将否定副词not放在be之后，如：

1.There aren't any pictures on the wall.

2.There isn't a bike behind the tree.

3.There will be no one at home tomorrow morning.

4.There aren't any flowers.

5.There is no bike behind the tree.

否定句：There be句型否定句式的构成和含有be动词的其它句型一样，在be后加上“not”。（名词）=not a/an/any+n.（名词）。注意：not a/an+n.（可数名词单数）；not any+n.（可数名词复数）；not any+n.（不可数名词）。例如：

There is an orange in her bag.

→There isn’t an orange in her bag.

There are some oranges in her bag.

→There aren’t any oranges in her bag.

There is some juice in the bottle.

→There isn’t any juice in the bottle.
