ПЕРЕВЕДИТЕ ПОЖАЛУЙСТА, ПРОШУ.

My school was a three-storeyed building situated in one of the residential districts of our city . There is a sports ground behind the school-building and a green lawn with flower-beds in front of it.
The school was built 30 years ago through its classrooms are light are spacious. There are maps and portraits, tables and charts on the walls of the classrooms. Our classroom is on the second floor and its windows face the school-yard.
Our lessons start at 8:15 a.m. and last till 14:10 p.m. So we have usually 6-7 lessons a day. Every pupil has a day-book where the teacher also writes down the marks each pupil had earned for his answers. The teacher also writes down the mark in the class register. The pupils are often called to the blackboard to do some exercises or to write some sentences. After every lesson the teachers gave us some home assignments both written and oral. At the next lesson the teachers check them up.
At the end of each year we are promoted to the next form.
