My school is a mixed 11-18 school. There about 1,150 students in my school, including 200 in the sixth form. It is called a Technology College and specializes in Computers and Maths. My school has over 1200 computers (including over 400 tablet PC’s)
I am in Year 8. Some subjects are compulsory like Maths, English, Science and a foreign language, but I like PE most of all.
My school day starts early in the morning. I leave home at 6:45 and walk 20 minutes to catch a bus to school. The bus is a special one just for kids going to my school. The journey on the bus takes an hour because it has to keep stopping to pick up other students along the way.
When I arrive at school, I collect my Tablet PC and go to my Tutor Room for Registration at 8:30. We listen to announcements (оголошення) to see what special things are happening at school today or this week.
At about 8:50 we leave Tutor Room to go to our First Period which starts in 10 minutes. Every day I have a different Lesson the first period. Normally it is Humanities but I also have Maths, Drama and Music, and French on the other days. Each period lasts an hour. We don’t use our Tablet PCs in all lessons because some rooms do not have enough power sockets. We use the Tablets to do our work on and to search the Internet. Our Tablet PCs are connected to a Network so we can send our work straight to our teachers. All my lessons are in different rooms and places around the school. I have different teachers for each lesson. I have a locker where I can store (зберігати) some of my stuff (речі).
I have a break from 11.00 to 11.20 when I can have a snack and play and chat with my friends. After the fourth period we have lunch. I bring a packed lunch to school but occasionally I have school dinners in the School Canteen that is open at Lunch Time and Break Time. Most hot food is served only at lunch time. Chips are only available (доступні, наявні) on Mondays and Fridays.
School ends at 3.10 and I sometimes stay after school for clubs.
Say if the following statements true or false.
1. The boy studies in a specialized school.
2. He likes foreign languages most of all.
3. He gets up early in the morning and walk to school.
4. Computer studies and maths are his compulsory (обов'язкові) subjects.
5. The first period starts at 9 o’clock.
6. Each period in their school lasts 60 minutes.
7. They don’t use their Tablet PCs in all lessons because they are not allowed (дозволено) to do it.
8. The boy keeps his things in his locker.
9. He always has lunch in the school canteen.
10. The students can buy chips in the canteen every day.
11. The boy stays after school for clubs every day.
