La interogativ, in cazul acesta, trebuie sa pui pur si simplu inainte propozitiilor cuvantul "Do"
Ex: Do They live in small houses?
La negativ, in cazul acesta, trebuie sa adaugi cuvantul "don't" unde trebuie
Ex: My friends don't often try to cook...
We don't buy or sell...
English people still don't eat...
