4. Образуй отрицательную форму предложения: (повышенный уровень)

Решение:

Для образования отрицательной формы в Present Simple используется вспомогательный глагол do/does с частицей not. После do/does глагол ставится в инфинитив без частицы 'to'.

1. Nikita is flying a kite. (jump)
   Nikita is not jumping. (Здесь используется Present Continuous, так как есть глагол 'is'. Отрицание строится с 'is not' и глаголом с окончанием -ing.)
2. Masha and Olya are playing a game. (talk)
   Masha and Olya are not talking. (Аналогично, Present Continuous. Отрицание с 'are not' и глаголом с -ing.)
3. Slava and Artyom are playing basketball. (play soccer)
   Slava and Artyom are not playing soccer. (Present Continuous. Отрицание с 'are not' и глаголом с -ing.)
4. Fedya is making a sandcastle. (climb a tree)
   Fedya is not climbing a tree. (Present Continuous. Отрицание с 'is not' и глаголом с -ing.)
5. Vanya is driving a car. (play basketball)
   Vanya is not playing basketball. (Present Continuous. Отрицание с 'is not' и глаголом с -ing.)
