IX. Прочитайте текст, ответьте на вопросы после текста.
I finished school last year, but sometimes I visit my teachers now. My school is old and it gives good education for all schoolchildren.
We went to school 5 days a week. Lessons began at 9 o’clock. We had 7 or 8 lessons every day. At 11.30 we went to school canteen and had lunch.
We had many subjects, but my class specialized in mathematics and I enjoyed it. I also liked sports lessons and computer programming. I wasn’t good at chemistry and I am glad I don’t need it now.
We usually had much homework and I did it till 8 p.m. every day. But at school we had many out-of-class activities. We had an orchestra and a choir and we often went to the concerts. Many children played basketball and volleyball and we watched games and matches every month. I went to drama club and we presented new plays 4 times a year.
