Does и do пишутся только в отрицательных и вопросительных предложениях.
Does пишется, когда подлежащее можно заменить на местоимение he/she/it. Например:
She doesn't like ice-cream. (Она не любит мороженое.)
Does he have a car? (У него есть машина?)
Когда подлежащее можно заменить на местоимение I/you/we/they, тогда пишем do. Например:
They don't want to go to the theatre. (Они не хотят идти в театр.)
I don't like milk. (Я не люблю молоко.)
Do we like celebrating New Year? (Нам нравится праздновать Новый год?)
Do you respect your teacher? (Ты уважаешь своего учителя?)
