"There is" and "There are"
The construction "There is" and "There are" are used to indicate the existence or presence of something. It helps to introduce or point out the existence of people, places, or things.

- There is is used when referring to a singular item or a non-countable noun.

Example:
There is a cat on the roof.
- There are is used when referring to multiple items or countable nouns.
Example:
There are many books on the shelf.

The basic structure of these constructions is:

1. Affirmative:
- There is + singular noun/non−countable noun
Example:
There is a beautiful garden in the backyard.

-There are + plural nouns

Example:
There are three bedrooms in the house.

2. Negative:
- To form a negative sentence, add "not" after "is" or "are."
Example:
There is not enough time to finish the project.
