Mrs Swan: I can't say sport is very useful for teens. Children who do a lot of sport often have no time for all the things teens like, such as meeting friends, walking and so on. Sport needs hard work and it is very competitive. Some children may become nervous and unhappy. More than that, children often get broken legs and arms and other injuries. There is no good in sport, it is necessary only to be active and to keep fit. And for it there are PE lessons at all schools. выписать неправильные глаголы​
