Question

como cambiar una oracion a negativa

Answer 1

Una oración en inglés afirmativa se diferencia de una negativa por el auxiliar, dependiendo del tiempo en el que se encuentre la oración afirmativa, por ejemplo:
PRESENTE:
don't: I, you, we, they
Doesn't: He, she, it

I don't work as a teacher at your school.

Affirmative sentence:

You didn't travel to London last year.
