Question tags are the short questions that we put at the end of sentences, especially in spoken English.

			You're coming, aren't you?
			He's not serious, is he?

If the main part of the sentence is affirmative, then the question tag is negative:

			It's warm, isn't it?
			They went also, didn't they?

If the main part of the sentence is negative, then the question tag is affirmative:

			She couldn't see it, could she?
			We won't know till tomorrow, will we?

If the main part of the sentence contains an auxiliary verb (or the verb "to be", then this is used in the question tag:

			They are away for a few days, aren't they?
			You weren't available, were you?
			She's Mexican, isn't she?
			It wasn't his turn, was it?
			You've got a cat, haven't you?
			He's got a new house, hasn't he?
			We can't go in there, can we?
			They couldn't hear me, could they?

If the main part of the sentences does not contain an auxiliary verb, then we use the verb "to do" in the question tag:

			She needs some help, doesn't she?
			He loved his work, didn't he?
			You come here often, don't you?

Depending on what we wish to say, the intonation of a question tag is different. If we are asking a real question (in other words, if we don't know the answer), then our voice rises on the question tag:

That's spelt with two n's, isn't it?

On the other hand, if we are sure of the answer and are only asking for agreement, our voice falls on the question tag:

It's your turn next, isn't it?
