Tag Questions

As tag questions (perguntas de confirmação) são estruturas muito comuns no inglês falado e escrito, usadas principalmente para confirmar informações das quais já temos quase certeza, ou para verificar algo sobre o qual estamos em dúvida. 

A lógica é simples: se a frase principal é afirmativa, a tag question será negativa, e vice-versa. A tag question geralmente repete o verbo auxiliar ou modal da oração principal, adaptando-o ao sujeito.
