Текст
Наступила поздняя осень. Стоит ненастная погода.Подул резкий ветер.Вот с берёзки летят жёлтые листья. На дорожках лежат красные листья осинки, бурные листья тополя. Ночь теперь длинная а день короткий . Улетают последнее птицы. В аллеях сада тихо. Из окрестных деревень потянулись машины в город. Фермеры везут морковь,кортофель,капусту,яблоки.
