По составить моя идеальная школа отношение учеников и учителей нужно

I'd have one for the first and second years and also for the third and fourth years. the playgrounds would be separate, one for the young children and the other for the senior forms. a wall would be separating them and there would be a door from one playground to the other. the classrooms would have carpets instead of lino. the desks would be painted and the chairs would have cushions. the chairs would also be painted. there would be a computer for every table in the classroom. there would be at least 12 videos for each classroom. the hall would be very big, about 40 metres long and 30 metres wide. the lessons would be interesting. there would be lots of french and german and english. there would be four floors at the school. there would be a lift to take us up. the staffroom would be much bigger than the one we have now. it would be light and cosy. there would also be a big library. there would be a lot of instruments: flutes, guitars, drums, etc. the school meals would have different food every day. there would be lots of visits to concerts and parks. the tests would be easier for children.
