Решение:
- The park keeper found some litter in the park. First he found a crisp packet. The packet was in the middle of the football pitch. Then he found an old comic. The comic was under a tree near the lake. Then he found some orange peel behind the fence next to the bus stop.
Обоснование выбора артиклей:
- 'the' используется, когда речь идет о чем-то конкретном, уже упомянутом или известном говорящим и слушающим (например, 'the park', 'the football pitch', 'the bus stop').
- 'a' используется, когда речь идет о чем-то неопределенном, о любом представителе класса (например, 'a crisp packet', 'a tree').
- 'an' используется перед словами, начинающимися с гласной буквы (например, 'an old comic').
