Some verbs / expressions have different question tags.
1. I am => aren't
- I am attractive, aren't I?
2. Positive imperative
Sometimes we use question tags with imperatives (invitations, orders), but the sentence remains an imperative and does not require a direct answer. We use won't for invitations. We use can, can't, will, would for orders.

- He has got a car, hasn't he?
6. There is / are

7. This / that is
- This is Paul's pen, isn't it?
8. When the subject of the main part of the sentence is anyone anybody, no one, nobody, none, neither, everyone, somebody, someone, everybody,etc., we use the Personal Pronoun “they” as the subject of the ‘tag’ part.
- Neither of them explained, did they?

9. The statement sentences with words such as neither no, none, no one, no body, nothing, scarcely, barely, hardly, hardly ever, seldom, etc. which are, strictly speaking, treated as negative, are followed by an ordinary positive ‘tag’.
