My name is...I'm 17 (years old).I am rather introverted and taciturn.I am often shy,but I think I look quite handsome.In my spare time I like to read and to play the basketball.My idols are Caron Butler,Kevin Garnett and Hakeem Olajuwon.I hope my speech here today will help me improve my English and will let you know me better so that we could become friends.

Hi!I'm...and I'm 17.I'm,relatively speaking,a quiet guy and I'm likely to be shy.But I am rather dapper in appearance.Reading and playing basketball are my favorite pastimes.I totally worship Caron Butler,Kevin Garnett and Hakeem Olajuwon.I hope that this speech will not only give me a chance to improve my English but also become good friends with all of you.
