My school
Dominic: "I hate school. Every morning the teachers make us get up at six o'clock and run five kilometres. Afterwards all the pupils are made to take a cold shower. The teachers never allow us to go to the nearest village. Every Sunday we are made to write a long letter home, but we are not allowed to complain about anything. In the evening they let us watch television only for two hours. We have to wear uniforms all the time and a certain colour of ribbon or ornament to keep the hair out of our eyes for safety reasons. Only in the last year the girls are allowed to wear make up and jewellery. Also we are not permitted to smoke either in school or outside it. I think all this is a violation of our rights!"
Andre: "I love my school. Actually, it is a lyceum near Versailles in France where pupils study foreign languages from nursery school right through to the final school-leaving exams. Throughout their schooling our pupils get regular secondary education and, besides, attend their national sections for six or eight hours a week, when they are taught by native speakers the language, literature and history of the country concerned. The school is for the bright. Standards are high and the workload is heavy. Candi­dates are carefully selected and may be invited to go elsewhere if they fall behind. Some pupils become fluent in three or even four languages and many go to universities abroad."
David: "I go to a modern experimental school which is called Summerhill. All the lessons are op­tional, it means that you can go to them or stay away from them. There is a timetable but only for the teachers. The children have classes according to their age or interests. Summerhill is possibly the happi­est school in the world because we have no truants, no fights and the children are not afraid of punish­ment."
Richard: "1 study in one of the most famous public schools in Britain. It was founded in 1894. The school is based in a country house and has a modern classroom block, a swimming pool, a music block, an art block for painting, print-making, clay-modelling and sculpture, a modern engineering workshop and a fully equipped science laboratory complex. It also has a small astronomical observatory and a satellite-TV installation for the modern language department. Besides the traditional sports and games our pupils may also go in for camping, canoeing, sailing and rock-climbing.
We also have several clubs and hobby activities like Printing, Electronics, Model-making and Drama. In senior forms the pupils are allowed a choice of subjects and their individual progress is monitored so that those of different abilities may be helped and encouraged. The working philosophy in the school is "To each to his/her ability."

Decide whether the following statements are true or false:
1. Dominic attends a boarding school.
2. The discipline in the school is not very strict.
3. Dominic and her friends complain about their school in their letters home.
4. All the girls in Dominic's school can wear cosmetics and jewellery.
5. Only very talented and hard-working students study in Andre's lyceum.
6. Andre's schoolmates can study several foreign languages at a time.
7. They don't have any other subjects besides the languages.
8. In Summerhill students are not made to attend classes.
9. David's schoolmates can choose the subjects according to their interests.
10. Students in Summerhill never miss classes.
11. Richard goes to a state school in the city.
12. Richard's schoolmates have a wide choice of clubs to enjoy their hobbies and interests.
13. Special attention is paid to the development of each student's abilities in Richard's school.
