Question tags are the short questions that we put on the end of sentences -- particularly in spoken English. There are lots of different question tags but the rules are not difficult to learn. In this video lesson Ceema explains, how to form a question tag -
Intonation
Question tags can either be 'real' questions where you want to know the answer or simply asking for agreement when we already know the answer.
If the question tag is a real question we use rising intonation. Our tone of voice rises.
If we already know the answer we use falling intonation. Our tone of voice falls.

Positive/negative: 
# If the main part of the sentence is positive, the question tag is negative. 
He's funny, isn't he?
You work in a bank, don't you?

# And if the main part of the sentence is negative, the question tag is positive.
She didn't finish her homework, did she?
She isn't coming, is she?

# Without auxiliary verbs: If the main part of the sentence doesn't have an auxiliary verb, the question tag uses an appropriate form of 'do'.
They speak fluent English, don't they?
We ran for hours in the park, didn't we?
