Our class is on the second floor of the school. This is a biology cabinet. It is spacious, light and warm. In the classroom there are two large windows, on the windowsills there are flowers in pots. The windows look out onto the street through which people walk and drive cars. The floor is covered with brown linoleum. The walls are painted yellow. In addition to the desks and the teacher's table, along the wall there is a long light cupboard, in which books, tables, teaching aids, models and herbariums are stored. All this is so interesting! We always maintain cleanliness and order in its class: every day my floors, wipe the dust, water the flowers. This office is the most cozy in the school, so we are lucky that it is ours.

Перевод:
Наш класс находится на втором этаже школы.

Это кабинет биологии. Он просторный, светлый, теплый. В классе два больших окна, на подоконниках – цветы в горшках. Окна выходят на улицу, по которой ходят люди и ездят машины. Пол покрыт коричневым линолеумом. Стены выкрашены желтой краской. Кроме парт и учительского стола, вдоль стены стоит длинный светлый шкаф, в котором хранятся книги, таблицы, учебные пособия, муляжи и гербарии. Все это так интересно!

Мы всегда поддерживаем чистоту и порядок в своем классе: каждый день моем полы, вытираем пыль, поливаем цветы . Этот кабинет самый уютный в школе, так что нам повезло, что он наш.
