Question Tags (Las preguntas coletillas)

En inglés es frecuente terminar las frases con otra frase corta, de signo contrario, la cual tiene la intención de pedir la opinión o buscar la aprobación del interlocutor: son las llamadas question tags (preguntas coletillas). Estas frases equivalen a: ¿verdad?, ¿no es verdad?, ¿no?, ¿no es así? ¿enserio?

Ejemplos:
PlayYou eat meat, don't you? (Comes carne, ¿verdad?)
PlayShe doesn't like to dance, does she? (No le gusta bailar, ¿no?)
PlayAlex and Sergio are friends, aren't they? (Alex y Sergio son amigos, ¿no?)
Grammatical Rules (Reglas gramaticales)
Para formar esta pregunta corta utilizaremos el auxiliar de la frase principal y su sujeto pero de signo contrario. Si no tuvieraauxiliar entonces utilizaríamos el auxiliar "to do".
Si la oración es afirmativa, la pregunta coletilla es negativa y viceversa.
Nota: Con el verbo "to have", hay dos posibilidades:
Ejemplos:
United Kingdom :PlayThey've got a dog, haven't they? (Tienen un perro, ¿no?)
United StatesPlayThey :have a dog, don't they? (Tienen un perro, ¿no?)


Excepción:
Con el verbo "to be" en la primera persona deoraciones negativas, se usa "aren't" en la pregunta coletilla.
Ejemplos:
I am not wrong, am I?I
am wrong, aren't I?
I am wrong, amn't I?
