Question tags

Las question tags (etiquetas de preguntas, literalmente) son preguntas que usamos para verificar que algo que pensamos que es cierto.
Por ejemplo: Your name is Peter, isn't it?
                     Tu nombre es Pedro, ¿no lo es?


Para formar una question tag necesitamos: un auxiliar del verbo (do, will...), un pronombre (he, it, they, she...) y una pregunta negativa si la frase es positiva o una pregunta positiva si la frase es negativa.

Positive verb, negative tag	Negative verb, postivie tag
It's cold today, isn't it?	You aren't happy, are you?
They live in Australia, don't they?	She hasn't been to Italy before, has she?
You'll ve OK, won't you?	You won't tell anyone, will you?
