1、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。

　　2、尊敬的老师，亲爱的同学们，大家早上好。我叫秦成，近年十七岁。我毕业于天桃中学，它是我们市里最好的中学，校园和我们校园一样美丽。我最喜欢的科目是数学，因为它是使很多学生抓狂的复杂科目。但是，我是一个喜欢挑战的学生，每当我解答出一道数学问题的时候，我感到一种巨大的成就感。除此之外，我喜欢各种各样的课外活动，因为我它们给我带来了多姿多彩的生活。在我看来，学习只是生活中的一部分，因此我们不应该被学习束缚。最重要的是，我很高兴能成为你们的同学。我希望我们可以一起学习，一起玩。
