A.
All students in the UK have to do PE or Physical Education at school until they are 16. The schools offer different activities. The most popular sport is football which is played by boys and girls. Students also play rugby, field hockey, and netball or do individual physical activities like athletics or gymnastics. Today, some schools also offer dance, fitness, or frisbee. The school sports facilities are always available to the students at lunchtime and after classes.

B.
Unfortunately, this school subject is not very popular with British students. The British government is considering different ways to deal with this problem. One idea is to introduce foreign languages from the age of 5. Another plan is to give students more choice. The languages traditionally studied in British schools are French, Spanish and German. Now the government wants to include Arabic and Chinese in the school curriculum.

C.
Mobile phones are permitted at school in the UK but students are not allowed to use them in class. School students can use their phones at break time. Teachers can take away phones if these rules are broken. However, according to some teachers, students don’t always follow the rules. The lessons are sometimes disrupted when students send texts, receive calls, look at social networking sites or watch videos.

D.
School lunches are a hot topic in the UK these days. Some students have lunch at home or take a packed lunch to school but more than a third of British school pupils have lunch in the school canteen. There is usually a main course, a dessert and a drink. School dinners must include fruit and vegetables, protein (for example meat, fish or cheese) and carbohydrates (for example rice or pasta). Parents often pay for their children’s food in advance online.

E.
UK schools are allowed to discipline pupils who behave badly. The list of serious and not-so-serious types of bad behaviour may include: missing school without permission from parents, not doing homework, wearing unsuitable clothes for school, cheating in exams, bullying, etc. There are several ways students can be punished. Sometimes the student has to write a sentence, for example I must not shout in class, many times (for example, 100 times) on a sheet of paper.

F.
A school prom is a formal party to celebrate an important date such as the end of secondary school. The idea is to have fun with your school friends and celebrate your time and achievements at school. Proms are held in June or July, around the end of exam time or the end of term. A secondary school prom often involves a big party and nice dresses. Most schools arrange a special dinner in the school hall.

G.
In the past, students were only allowed to take a gap year (a period of time, when a student takes a break from formal education) if they had to retake exams or had health problems. But now universities positively encourage a gap year, and employers are happy to give jobs to students who take a gap year. They think that a gap year can give young people useful learning experiences, help them pick up new skills and make them more independent.
