一般的高中作文分为三段是标准的格式。
第一段：我叫什么名字，来自哪个初中，家乡在哪
第二段：着重介绍自己的兴趣爱好，性格（要有有趣的故事）
第三段：表达自己很愿意和新同学一起在高中的三年学习生活 大致是这样：
I‘m glad to be here introduce myself. My name is **,and I come form **junior high school. I am a native.
To be honest, I'm a kind person. If someone is in trouble,I ofen give my heip to them. And I still remember the thing happened last month.(然后叙述一下你遇到的这件事情，并且能证明你是一个乐于助人的人）..................................................If there is only one word for me to describe my character, the word would be "optimistic".(然后叙述你乐观表现在哪些方面）
It is a great honour for me to be a member in this class. It would be intresting in the after three years and I wish all of us can enjoy the journey during the study.
这样的话，应该超过300字了吧。祝你好运呗
