Dear Mrs Kong,
I hear that monitor is needed in our class this new term. I'd like to have a try.
You know that I am good at all the subjects. I've got many advantages, such as good health, great patience and good relationship with my classmates. I think about others more than my self. All of my classmates think I'm helpful. So I hope you will give me the chance. I'll work hard.
Best wishes!
Yours,
Qiao Bo

亲爱的孔老师：
我听说新学期我班需要一位班长，我愿意试一试。
您知道我多门功课都好。我有许多优点，像身体好，有耐心，与同学关系好等等。我想到别人更多，胜过我自己。所有的同学都认为我是助人为乐的。因此我希望你能给我一个机会，我会努力的。
祝你好运!
你的，
乔波
