A tag question is a short attached question added at the end of a sentence.
Speakers use tag questions chiefly to make sure their information is correct or to seek agreement.*
Examples
-Jack can come, can't he?
- Fred can't come, can he?
Auxiliaries and tag questions :
Auxiliaries, including the modals, are frequently used in tag questions. The tag repeats the auxiliary used in the sentence. If there is no auxiliary in the main sentence, dois used in the tag for the simple present and did for the simple past. Some auxiliaries; however, do not make good tag. If the main statement is affirmative, then the tag must be negative; if the main statement is negative , then the tag must be affirmative.
Examples :
- Hank runs every day, doesn'the?
- John ran ten miles yesterday, didn't he?
- Bill won't graduate this year, will he?
- Betty can't go with us, can she?
- You surely could do better, couldn't you?
- We should leave for the airport, shouldn't we?
- John isn't about to graduate, is he?
- Some of them have been notified, haven't they?
- Some houses will be torn down, won't they?
- She hasn't been married before, has she?
- When have to is used, the tag becomes a form of do.
Examples :- Mark and Willie don't have to move, do they?
- Mary had to see a doctor, didn't she?
- We don't have to be there by
- The report has to be read by tomorrow; doesn't it?
A tag question also conveys certain expectation on the part of the speaker. A tag in the affirmative conveys the expectation of a negative answer; a tag in the negative conveys the expectation of an affirmative answer.
