Olá
japerito,
Nas tag questions você deve olhar o verbo da oração. Caso ele seja um verbo de ação, sem auxiliar, a tag question deverá ter no final: do/don't ou does/doesn't seguido do pronome.
He swims, doesn't he?
We make delicious cookies, don't we?
Quando o verbo indica estado ou qualidade, sem auxiliar, no final temos: is/isn't ou are/aren't seguido do pronome.
You're are awesome, aren't you?
My mom is a teacher, isn't she?
Além disso, se temos modal verbs ou auxiliares, nós teremos:
You
have moved from Italy, haven't you? (Present perfect)
You
ought to listen to the teacher, oughtn't you?(Modal verb)
She
can't swim, can she? (Modal verb)
We
won't do the dishes, will we? (Simple future)
Before my father passed away, he
had had a job in Coca-Cola, hadn't he? (Past perfect)
By the end of the century, our society
will have achieved equality, won't she? (Future perfect)
Your cat
was walking near from here when he was attacked by a dog, wasn't he?
Espero ter ajudado
