переведите пожалуйста My school was very different from most school. It was in a lovely old house in a forest . There were only sixty pupils. There weren't many facilities , but there was a good library if you wanted to look up information or catch up with your work. You won't believe this, but we didn't have to go to lessons! And there was no homework or test,or anything like that, we could do what we wanted. If we wanted to study, we just went to the teachers and asked them to help us. At first, I was bored! Then I got interested in science and computers, and I studied science with a teacher who I got on with. I liked it so much that now I'm studying engineering at university and I want to go on to do further research. There were lost of other activities at school you could take up if you wanted-sport, painting and acting. The best thing was that we were free, and the school was democratic. Everything was decided at school meetings, and everyone could vote-each student had the same vote as the teachers. We decided all kinфds ( так в учебнике написано) of things-we even chose the teachers! A lot of people don't believe me, but it worked really well.
