One possible version:

Dear Tony,

I am Li Hua, a boy of 16 from China. I know you want to make an e-pal with a Chinese on the Internet. I want to be your friend and wish to know more about the culture of the USA.

I’m a sociable and supportive person who likes talking with people and helping with their problems. I’m good at English and I think we can communicate with each other by sending e-mails or chatting on the Internet. I like table tennis, enjoy singing and I’m crazy about popular music. At the same time, I like travelling around in my spare time. I hope you can come to visit China, and I’ll show you around many places of interest.

I’m looking forward to your early reply.

Yours,

Li Hua

题目分析：本文是一封电子邮件应用文，结交笔友，介绍自己及交友目的。内容提示较详细，学生容易把握写作要求和写作目的。考生在写作之前要认真审题，根据提示写作主要有三段内容，第一段开门见山表明写邮件的目的；第二段介绍自己并提出想结交的目的及打算；第三段结束，提出自己的希望。另外，要注意文章的时态，用一般现在时。人称用第一、二人称单数。再有就是不能根据提示内容逐字逐句的翻译形成汉式的英语，应该注意句子的衔接，以提高作文的档次。

【亮点说明】文章符合邮件书信的写作要求，要点齐全，表达思路明确，知识点运用恰当到位，文中使用了非常好的短语和句子为文章增色不少，比如on the Internet, know more about, places of interest和look forward to 等， 还运用了同位语：I am Li Hua, a boy of 16 from China.避免重复。定语从句：I’m a sociable and supportive person who likes talking with people and helping with their problems. 等。并注意了句子的衔接如：at the same time等。
