'are you running? ты бежишь? - почему не is you running? ведь are - когда несколько, а is один. you-один'
Я немного запутался. Не можете ли вы сказать другими словами, а то я не понимаю вопрос.
--------------------------------------
Are - не только несколько. Если вы о разнице ты/вы, то в английском языке всё сводится к одному you.
You может означать и ты, и вы.
1.
2) Are you seeing
3) aren't coming
4) is going to
5) Is Daniel playing
6) are flying, I am not going
7) is she doing
8) are you meeting
2.
2) I am studying maths later today
3) Helen isn't playing tennis in the competition on Thursday
4) Are Lucy and Matt watching the film on TV tomorrow night?
5) Where are you and your friends meeting tomorrow?
3.
2) Are Tom and Charlie playing football later?
Yes, they are.
3) Are Emily and Alex going to the cinema tomorrow?
No, they aren't.
4) Is Olivia going to Paris next week?
Yes, she is.
5) Is Kate singing in a competition on Saturday?
Yes, she is.
6) Are you visiting your cousins this summer?
No, I'm not.
You - и ты, и вы. Поэтомy всегда are.
Объяснение:
Спряжение глагола to be в настоящем времени:
I - am
You, we, they - are
she, he, it - is.
