My school is large and light. There are three floors in it. There is a gym, a library, a canteen and a few classrooms on the ground floor. There are many classrooms and a teachers’ room on the first and on the second floors. Our classrooms are very large and light. There are twelve desks, a teacher’s table, a blackboard and many flowers in our classrooms. My favourite school subjects are English, History and Literature. I’m fond of sport and music. So I two years ago I joined our school clubs: Basketball club and Musical club. My school life is wonderful. There are lots of concerts, performances and sport competitions in our school. My classmates and I often take part in different school events. I have a lot of friends in my class.  Our teachers are kind and intelligent and my classmates are smart and friendly.     

Моя школа очень просторная и светлая. В ней три этажа. На первом этаже тренажерный зал, библиотека, столовая и несколько кабинетов. На втором этаже много классов и учительская. Наши классные комнаты очень большие и светлые. В наших классных комнатах двенадцать парт, учительский стол, доска и много цветов. Мои любимые предметы в школе: английский, история и литература. Я люблю спорт и музыку. Поэтому я два года назад я вступил в школьные кружки: баскетбольную секцию и музыкальный кружок. Моя школьная жизнь прекрасна. У нас много концертов, спектаклей, спортивных соревнований в нашей школе. Мои одноклассники и я часто принимаем участие в различных школьных мероприятиях. У меня много друзей в моем классе. Наши учителя добрые и умные и мои одноклассники умные и доброжелательные.
