Present Continuous образуется при помощи вспомогательного глагола to be в настоящем времени (am, is, are) и формы причастия настоящего времени (Present Participle) смыслового глагола, т.е. глагола с окончанием -ing:
I am playing.
He is playing.
We are playing.
Отрицательная форма: am/is/are + частица not + глагол с окончанием ing:
I am not playing.
He is not playing.
We are not playing.
Вопросительная форма: am/is/are + подлежащее + глагол с окончанием ing
Am I playing?
Is he playing?
Are you playing?
В специальном вопросе вспомогательный глагол ставится перед подлежащим, а перед вспомогательным глаголом используется нужное вопросительное местоимение (what, where, why и др.):
Where am I playing?
Why is he playing?
With whom are you playing?
В вопросе к подлежащему вопросительное местоимение who ставится перед сказуемым вместо самого подлежащего (в данном вопросе всегда используется вспомогательный глагол is):
Who is playing?
Вопросительно-отрицательная форма: amn't/isn't/aren't + подлежащее + глагол с окончанием ing или am/is/are + подлежащее + частица not + глагол с окончанием ing:
Am I not playing?
Is he not playing? (Isn't he playing?)
Are we not playing? (Aren't we playing?)
В разговорной речи используются сокращения:
am= 'm
is ='s
are='re
am not='m not
is not= isn't='s not
are not=aren't='re not
