We spend much time in our classroom and it’s very important for us to keep it clean and nice. Our classroom is on the ground floor of the school building. There are three large windows in it, so the room is quite light. The windows face our school sports ground. We grow and water a lot of beautiful plants on the window-sills.
The pupils sit at their desks during the lessons. There are three rows of desks with chairs in our classroom. The folding board is dark-green. We write with coloured pieces of chalk on it. There is a teacher’s table with a computer on it and a bookcase next to the board. We study Maths in our class, that is why there are portraits of great scientists, formulas and diagrams on the walls. There is also our wall newspaper which reflects the latest interesting news and birthdays in our class.
I am glad to have a friendly and united class. There are 30 pupils in it: 18 boys and 12 girls. Quite many of them are talented and smart children. I have many friends among my classmates and I share the desk with my best friend Pete. We usually help each other with doing our homework. We take part in different school activities together. We also attend drama classes at school. I really enjoy it and have much fun there. Our teacher often helps us organize class contests, concerts and tea-parties. We always congratulate our classmates on their birthdays. These events really unite us as a big family.
My classmates and I often socialize outside the school. We like going to the cinema and cafes together. We also play football or volleyball. In the evenings we chat and exchange photos and videos in social networks.
Перевод
Мы проводим много времени в своем классе, и для нас очень важно, чтобы в нем было чисто и красиво. Наш класс находится на первом этаже школьного здания. В нем три больших окна, поэтому комната довольно светлая. Окна выходят на школьный стадион. Мы выращиваем и поливаем много красивых цветов на подоконниках.
Во время уроков ученики сидят за партами. В нашем классе стоят три ряда парт со стульями. Раскладная доска темно-зеленого цвета. На ней мы пишем цветными мелками. У доски стоит учительский стол с компьютером и книжный шкаф. Мы изучаем математику в нашем классе, поэтому на стенах висят портреты великих ученых, формулы и таблицы. Здесь также висит наша стенгазета, отражающая последние интересные новости и дни рождения в нашем классе.
Я рад, что у нас сплоченный и дружный класс. В нем 30 учеников: 18 мальчиков и 12 девочек. Довольно многие из них – талантливые и умные дети. У меня много друзей среди одноклассников, и я сижу с моим лучшим другом Петей за одной партой. Обычно мы помогаем друг другу делать уроки. Мы вместе принимаем участие в различных школьных мероприятиях. Мы также ходим в театральную студию в школе. Мне там очень нравится, и я весело провожу время. Наша учительница часто помогает нам организовывать классные состязания, концерты и чаепития. Мы всегда поздравляем одноклассников в день рождения. Эти события очень сближают нас, как большую семью.
Мы часто общаемся с одноклассниками и за пределами школы. Нам нравится ходить вместе в кино и в кафе. Мы также играем в футбол или волейбол.

My favouritedidn’t like any sport in my childhood but today swimming is my favourite. My father is a very good swimmer, so he was the one who taught me how to swim when I was 6 years old. But I didn’t start swimming seriously until I was 15 when I learnt many advantages in this activity. First of all, I don’t get hot and sweaty like we do with other kinds of sports. Besides, it’s not a team game so it doesn’t matter if I’m not quite good at it. As far as I know, swimming also increases my lungs capacity, it develops my breathing technique and makes my heart pump better. And it burns a lot of calories too. So I started going to the swimming pool because I needed more exercise to stay fit, physically strong and healthy. For me it’s the best way to relieve my daily stress and tiredness.
I go the local swimming pool for adults twice a week in the evenings. The sessions last for one hour, from 7 to 8 p.m. I really enjoy the time there. There are no children screaming and jumping in the pool. I just swim up and down quietly along my own lane, marked with ropes. My personal favourite stroke is freestyle. It is the fastest of the four primary strokes. I am also fond of backstroke. Floating on my back is so relaxing and soothing. The equipment for my favourite sport is minimal, so I don’t spend much money on it. All I need is a swimming costume and a towel. Sometimes I wear waterproof goggles and a swimming cap to protect my eyes and hair from the chlorine in the water. Although I find them rather uncomfortable.
Swimming is popular among both children and grown-ups. And it’s a perfect sport for me because it makes me feel great.
