Unit 50. Tag questions (are you? doesn’t he?, etc.)

A

You’re not working late, are you? It was a good film, wasn’t it?

Are you? and wasn’t it? are tag questions (= mini-questions that we put on the end of a sentence). In tag questions we use the auxiliary verb (see Unit 49). For the present and past use do/does/did: They came by car, didn’t they?
B
Normally we use a positive tag question with a negative sentence:

negative sentence + positive tag Tom won’t be late, will he? They don’t like us, do they? That isn’t George over there, is it?

And normally we use a negative tag question with a positive sentence:

positive sentence + negative tag Ann will be here soon, won’t she? Tom should pass his exam, shouldn’t he? They were very angry, weren’t they?
