Tag Questions

Tag questions are short questions that often come at the end of sentences in speech, and sometimes in informal writing.

Harry can't go, can he?

Note:

1. The tag question comes after a comma at the end of a statement.

It's hot today, isn’t it?

2. The adverb in a tag question is always an auxiliary or a modal auxiliary.

She doesn’t come home early, does she?

3. The subject in a tag question is always a pronoun. The auxiliary and pronoun refer to the verb and the subject of the statement.

The students worked hard, didn't they?

Remember:

A. When the verb in the statement is affirmative, the auxiliary in the tag question is negative.

The teacher will give a test tomorrow, won't he?

B. When the verb in the statement is negative, the auxiliary in the tag question is affirmative.

My classmates didn't do well on the exam, did they?

C. We often use negative sentence + positive tag to ask for things or information.

"You don't know where Karen is, do you?" "Sorry, I've no idea."

D. In speech, we can show the exact meaning of a tag question by the intonation. If the tag is a real question – if we really want to know something and are not sure of the answer – we use rising intonation: the voice goes up. If the tag is not a real question – if we are sure of the answer – we use a falling intonation: the voice goes down.

Exceptions:

1. ought to => shouldn't: We ought to visit him, shouldn't we?

2. ought not to => should: You ought not to lose your confidence. Should you?

3. Let's => shall: Let's play football, shall we?

4. Let's not => shall: Let's not talk about that, shall we?

5. may => may not: It may rain, may not it.

6. might => might not: He might take a nap, might not he?

7. am => aren't: I'm a good student, aren't I?

8. most imperative verbs => will you: take a few days off, will you?

9. a few imperative verbs => can't you: Shut up, can't you?

Examples:

· Your sister Mary has a native English teacher, doesn't she?

· You're going to check that this book is by Stephen King, aren't you?

· Tom's aunt has never been to school, has she?

· Fred and his wife are going to buy a huge house in the country, aren't they?

· The Smiths never go on vacation in August, do they?

· Jim has to go to a psychologist and ask for advice, doesn't he?

· She has to clean the room, hasn't she?
