Question

4 frases afirmativas, 4 frases interrogativas e 4 frases negativas usando was e were

Answer 1

Afirmativas:I was drink(ing) waterShe was enjoy(ing) you
 Negativas:She wasn't study(ing)He Wasn't eat(ing)

interrogativas:Was he Stress(ed)

Obs: Para o amigo ali que respondeu errado , quando colocamos were ou was e colocamos um verbo em seguida se torna uma palavra no passado continuo , senão um adjetivo ai seria simple past

Ex Continuous Past: She was drinking water , Was she drinking water , she wasn't drinking water.
Ex Simple Past: She was drunk , Was she Drunk  , She Wasn't drunk.
