распределите заголовок.
A. Activities after school
B. Free time between lessons
C. School clothes
D. School subjects
E. Homework
F. School day begins
1. I get up at 7.30 and get dressed for school. I don't live far from school, so I walk there with my friends, Brian and Gemma. On Mondays we all start the day with Assembly in the school hall at 8.50. The headteacher talks to us and gives us information about school events.
2. This year I've got nine subjects. We all study English, Maths and Science, and then we choose other subjects. My favourites are IT and Art&Design. Brian likes Spanish and Japanese. Gemma is brilliant at Maths, so she goes to an Advanced Maths class.
3. We have 20 minutes for break in the morning and an hour for lunch. Some students bring sandwiches to school for lunch, but my friends and I always eat in the dining room where you can get a hot meal every day.
4. Lessons end at 4 o'clock, but on Mondays and Wednesdays I stay at school until 5 o'clock. I go to the Photography Club and the Athletics Club. There are lots of clubs and activities at our school. Brian belongs to the Film Society and Gemma plays in the school orchestra.
5. At the end of the day I always spend two hours on homework — sometimes three hours. We get lots of homework now. We've got our exams in June, so there's always lots of work to do
