Объяснение:

First Conditional в английском языке нужен для того чтобы описать возможный результат в будущем при определенных действиях в настоящем. Например: если ты будешь много заниматься, то ты обязательно поступишь в университет. If you study a lot, you will definitely enter the university. Важно помнить что хотя мы на русском говорим в будущем времени (если будешь заниматься), то в английском после слова if (если) нужно использовать настоящее время (Present Simple).Структура предложения: if+существительное (noun)+ verb in present simple, существительное+ will+ начальная форма глагола без to
