同学，为你解答：

Dear all,

My name is Jack. I am 15 years old. I am from Shenzhen City, Guangdong Province. I am very glad to meet you all and hope we can get along with each other very well. I like reading, listening to music and play basketball. Because reading can make us more and more cleaver and increase our knowledge. Listening to music can help people reduce pressures and make us feel happy. As is know to all, playing basketball is a very good exercise for us to keep health.I also like riding bike too. I ususall go riding during the weekend. Riding has a lot of fun and can help to reduce the pollutions. It is also a very good exercise for us to keep health. I hope we can be good friends and play together.

That’s all! Thanks for your attention!
