Question

que esta mal en estas frases ? Does the teacher giving homework every day? / I didn't knew Tom in 2003 / There's much noise here. I want to leave

Answer 1

en algunas oraciones tienes dos verbos por lo que puedes quitarle el pasado y hacerlo en presente o viceversa.
también hacer dos oraciones:

Presente: Does the teache give homework everyday? 
Is the teacher giving homework everyday?

Pasado: I didn´t know Tom in 2003
Presente: I Knew Tom in 2003

There is too much noise here. I want to leave.

saludosss
