Question

Passe para a forma contraída .a frase . She is not a estudent

Answer 1

She isn't a student.

Answer 2

A forma contraída seria a forma simplificada (e mais rápida de se escrever)
Temos no verbo to be:
i am = i'm
you are = you're
he is = he's
she is = she's
it is = it's
we are = we're
they are = they're
you are = you're

Quando adicionamos o not ao verbo to be, fica:
am not = am not (não tem abreviação)
is not = isn't
are not = aren't

Dessa forma:
She isn't a student
