Our favourite Olympic sport
I like football best.It’s popular around the world.English people are good at football,but Chinese people aren’t good at football.However,Chinese people still like football very much.Lots of children want to be a footballer in the future.Football is popular,because it’s very exciting.Basketball is exciting,too,but football is more exciting than basketball.Watch a football match is a relax thing,but play football is very tiring thing.So if you want to be a good footballer,you must practice every day.
