     Martin Glenn is fifteen years old and he likes sports very much．There's nothing unusual about that，but Martin's family is a bit different．They all like sports and they run a family sports business(生意)．

Martin's mom and dad set up the business ten years ago，when Martin was five．His dad Worked in a bank before that，but he hated it．He wanted a job that had to do with his love for sports．At first，they had a small shop and only sold sports clothes．But the business soon grew．Now they have a big shop and it sells different kinds of sports equipment (器材)．

    Martin can't really remember life before the business．“I have an early memory of helping my mom and dad in the shop．”he said．Now, Martin is very interested in the shop and the things they sell．“I am responsible(负责)for choosing what to sell each year．I love seeing all the new designs(设计)．And of course each year I get my new football shoes at a really good price!”

    Martin's sister Amy helps with the business，too．She serves customers(顾客) in the shop on the weekend．She says,“It isn't easy, especially when customers  aren 't happy about something !”But she enjoys being part of the family team．

    Martin's mom organizes online orders．She started selling online about five years ago and it's now an important part of the business．Both Martin and Amy want to work in the family business in the future．“It is hard work．But I know that if Martin and I work together, we'll make the business even better!”said Amy．
