4. He plays football in his school team. Tomorrow he won't be play at the stadium. It's his second match. Tomorrow he will play at the stadium. It's his second match. Tomorrow he is play at the stadium. It's his second match.

Для решения данного задания необходимо выбрать правильный вариант продолжения предложения, учитывая грамматические и смысловые связи.

Рассмотрим предложенные варианты:

• Tomorrow he won't be play at the stadium. It's his second match. - Грамматически неверно, так как после "will" должен идти глагол в инфинитиве без "to".
• Tomorrow he will play at the stadium. It's his second match. - Грамматически верно и логически связано с предыдущим предложением.
• Tomorrow he is play at the stadium. It's his second match. - Грамматически неверно, так как после "is" должен идти глагол с окончанием "-ing".

Правильный вариант:

• Tomorrow he will play at the stadium. It's his second match.

Ответ: Tomorrow he will play at the stadium. It's his second match.
