Good morning, my admirable teacher and my dear fellows. My name is Qing Cheng and I’m in my 17 years old. I graduated from theTianTaoMiddle school, which is one of the best middle schools in my city. Its campus is as beautiful as ours. My favorite subject is math, because it’s a complicated subject that drives a lot of students crazy. But I am a student who likes challenges and I can feel great achievement when I solve a math problem. Besides, I like various extra curricular activities, because they can bring me a colorful life. In my opinion, study is just a part of our life, so that we should not be constrained by it. The most important is that I am happy to be a classmate of you. I hope we can study as well as play together.
