5. переделайте данные предложения в отрицательные. используйте глаголы do и does. 1. mary takes the dog for a walk in the evenings. 2. peter buys a morning newspaper every day. 3. i come to every lesson. 4. we go to the seaside every summer. 5. you go shopping on saturday mornings. 6. peter plays the piano very well. 7. the sun rises in the east. 8. my big brother knows everything. 9. dogs dont like cats. 10. all children like chocolate. 11. it rains very often in autumn.

Он, она, оно - does, doesn't (при этом -s на конце глагола убирается. Например:
Mary walks -> Mary doesn't walk
The sun rises -> The sun doesn't rise
Peter buys an ice cream -> Peter doesn't buy an ice cream)
Но если "он" или "она" или "оно" во множественном числе, то в отрицании или вопросе ставится do (Например:
Girls don't like ice cream. (Девочки (в ед.ч. "она") не любят мороженое)
Cats don't like dogs. (Коты (в ед.ч. он) не любят собак)).
Я, мы, ты, вы - do, don't (в отличие от "он, она, оно" в конце глаголов -s не ставится:
I walk -> I don't walk
We buy -> We don't buy
You know -> You don't know)
