Read the rules about tag questions and then take the quiz!
Tag questions are used  to verify or check information that we think is true or to check information that we aren't sure is true.  
Tag questions are added to the end of a statement. If the statement is negative, then the tag is positive. The statement and the tag are ALWAYS separated by a comma.  EXAMPLE:
You don't live here, do you?

Negative statement    +

positive tag

If the statement is positive, then the tag is negative. EXAMPLE:

You live here,

don't you?

positive statement +

+ negative tag

 
The verb in the statement should be the same tense as the verb in the tag.

EXAMPLE: 

You like dogs,

don't you?

present tense

present tense

She ate lunch,

didn't she?

past tense

past  tense

If the verb used in the statement is the TO BE verb, then the verb used in the tag is also the TO BE verb. Look at the following examples:

She's from France, isn't she? 

They aren't your neighbors, are they? 

If another verb (not TO BE) is used in the statement, then the auxiliary do is used in the tag. Look at the following examples:

He eats meat, doesn't he?

She doesn't live in Brooklyn, does she? 

If the perfect tense is used in the statement, then the auxiliary have is used in the tag. Look at the following examples:

They've visited your new house, haven't they?

You haven't eaten yet, have you?

If a modal (can, could, will, should, etc.) is used in the statement, then the modal is used in the tag. Look at the following examples:

You can dance, can't you?

They should meet, shouldn't they?
