Question

Helen decided to come.
That student caused some problems.
They told me the secret.
We saw them at the club.
Como Passar essas frases para forma interrogativa e negativa?

Answer 1

Você terá que utilizar o auxiliar DID, em todas os casos (tanto na forma negativa quanto na forma interrogativa). Note que eu abreviei "did not" e utilizei "didn't" em seu lugar, nas formas negativas. Prossigamos:


a) Negative form: Helen didn't decide to come/Helen decided not to come
     Interrogative form: Did Helen decide to come?

b) Negative form: That student didn't cause some problems
     Interrogative form: Did that student cause some problems?

c) Negative form: They didn't tell me the secret
    Interrogative form: Did they tell me the secret?

d) Negative form: We didn't see them at the club
     Interrogative form: Did we see them at the club?
