     For many young people sport is a popular part of school life. Being in one of the school teams and playing in

matches is very important. If someone is in a team it means a lot of extra practice and often spending a Saturday

or Sunday away from home, as many matches are played then.

     In can also involve travelling to other towns to play against other school teams and then staying on after the

match for a meal or a drink. Sometimes parents, friends or the other students will travel with the team to support

their own side.

     When a school team wins a match it is the whole school. It means the whole school feels proud, not only the

players. It also means a school becomes famous for being good at certain sports and students from that school

may end up playing for national and international teams, so that the school has some really famous names.
