1   Quando o verbo na oração principal estiver na afirmativa, o verbo na question tag é normalmente empregue na negativa:

Exemplo:   It's easy, isn't it?

2   Quando o verbo na oração principal é be, emprega-se o mesmo na question tag:

Example	Significado
I'm late, aren't I? (1)	Estou atrasado, não estou?
You're sick, aren't you?	Estás doente, não estás?
He's angry, isn't he?	Ele está zangado, não está?

He was here, wasn't he?	Ele esteve aqui, não esteve?
It was cold, wasn't it?	Estava frio, não estava?
They were here, weren't they?	Estiveram aqui, não estiveram?

(1) note a diferença entre os dois verbos (am, are) na 1ª pessoa do singular - aqui é uma excepção

3   Quando o verbo na oração principal é there+be, emprega-se o mesmo na question tag (mas em forma invertida):

Example	Significado
There's a lot of hunger in the world, isn't there?	Há muita fome no mundo, não há?
There are a lot of people, aren't there?	Está muita gente, não está?
There was something wrong, wasn't there?	Houve alguma coisa de errado, não houve?
There were a lot of people, weren't there?	Estavam muitas pessoas, não estavam?

4   Quando o verbo na oração principal é precedido por um verbo auxiliar, emprega-se este último na question tag:

Example	Significado
You're joking, aren't you?	Estás a brincar, não estás?
She can swim, can't she?	Ela sabe nadar, não sabe?
He'll be here, won't he?	Ele estará cá, não estará?
He has finished, hasn't he?	Ele acabou, não acabou?
You would do it, wouldn't you?	Tu farias, não farias?
There has been a lot of rain, hasn't there?	Tem caido muita chuva, não tem?

5   Quando o verbo na oração principal é precedido por mais que um verbo auxiliar, emprega-se sempre o primeiro dos auxiliares na question tag:

Example	Significado
He's going to do it, isn't he?	Ele vai fazê-lo, não vai?
You've been running, haven't you?	Estiveste a correr, não estiveste?

6   Quando o verbo (2) na oração principal não é precedido por um verbo auxiliar, emprega-se do, does ou did na question tag:

Example	Significado
You remember, don't you?	Lembras-te, não te lembras?
She likes it, doesn't she?	Ela gosta, não gosta?
They saw him, didn't they?	Eles viram-no, não viram?
