A question tag is the short question added to the end of a statement — like isn't it? or do they? The core rule is straightforward: positive statement + negative tag, and negative statement + positive tag. But getting the right auxiliary verb requires careful attention. The grammar review below explains the full formation rules. This is exercise 1 of 2.
Grammar reviewQuestion tags — structure and formation
A question tag is a short question added to the end of a statement, used to confirm information or invite agreement. The key rule is that the tag is always the opposite of the main clause: if the statement is positive, the tag is negative, and vice versa.
Structure: auxiliary verb + pronoun (+ not for negative tags) “She is coming, isn’t she?” “They don’t know, do they?” “You haven’t met him, have you?”
Choosing the right auxiliary:
Use the same auxiliary as in the main clause. If there is no auxiliary, use do/does/did. “He works here, doesn’t he?” (no auxiliary → use does) “She went home, didn’t she?” (no auxiliary → use did) “They can swim, can’t they?” (auxiliary = can)
Pronoun agreement:
The pronoun in the tag must match the subject of the main clause. “The dog is barking, isn’t it?” “Your parents are home, aren’t they?”
Special case — I am:
The tag for I am is aren’t I? (not amn’t I): “I’m right, aren’t I?”
