Объяснение:

Там, где в русском языке нужно использовать придаточное предложение с союзом "чтобы", в английском достаточно воспользоваться инфинитивом с частицей to:

Jake went to the bookstore to buy a recipe book. = Джейк пошел в книжный магазин (чтобы) купить книгу рецептов

Laura went home to watch TV. = Лаура пошла домой, чтобы посмотреть телевизор.
