There is / There are

There is / There are 


1.Use "There is" for singular nouns and things you cannot count.
Examples: There is an apple on the desk.
                   
2.Use "There are" for plural nouns; that is to say, we use there are with a plural subject.
Examples: There are four windows in my room.


3.To say the opposite, (the negative form of this structure), use isn't  (is + not)    or    aren't   (are + not)
Examples: There isn't a telephone in the kitchen.

4.To make questions, (to ask whether something exists or it doesn`t)  just change the order of there is and there are......
Examples: Is there a Post Office near hear?
                  Yes, there is.
                   No, there isn`t.

5.To express the idea of quantity,  we usually  have to use "some"  and   ''any"  with there is and there are. This happens when we have to mention an unspecified amount of something, for example,  when we are using uncountable nouns.


We generally use some for positive statements, and any for negative and interrogative ones.
Examples:   (positive statements) There is some water in the bottle.
                   (negative statements)  There aren`t any apples
                   (interrogative statements) Are there any chairs in your room?
