Question tags are very common in spoken English. We use them to keep conversation going by involving listeners and inviting them to participate.
The most common patterns are;
positive sentence – negative tag or negative sentence – positive tag
- You work in a law office, don’t you?
- Your father will retire in July, won’t he?
- Your English has improved a lot in the last couple of years, hasn’t it?
- She used to live in Istanbul, didn’t she?
- She isn’t honest, is she?
- We don’t have to go to school next week, do we?
- She isn't really the sort of person you want to marry, is she?
- He didn’t use to smoke, did he?
When using tag questions, watch for 4 points:
* What tense is the verb?
* What kind of verb is it? (to be/other verbs)
* Is the sentence affirmative or negative?
* Does the pronoun need to be changed?
Look at these examples:
Jack's happy, isn't he?
Susan's tired, isn't she?
It's warm today, isn't it?
They're busy, aren't they?
they are -> aren't they?
You and I are fun people, aren't we?
You're quiet, aren't you?
I'm intelligent, aren't I? or am I not?
