Question

qual e a forma interrogativa e negativa de he is very studious ?

Answer 1

Is he very studious?
he is not very studious.
Na forma interrogativa vc troca o verbo tube: he is por Is he. She is por Is She, I am por Am I. Depois continua com o resto da frase, e claro, acrescente o "?"
Na negativa, é depois do verbo, ex: he is Not. you are Not.
Espero ter ajudado.
