A Letter of Application

1. 我是大二学生(sophomore)，现申请从自动化系转到商务管理系
2. 申请的主要原因
3. 对转系带来的麻烦表示歉意，并希望有关领导能同意我的申请

Dear Sir/Madam,

I am a sophomore with major in Automation. Though I have made a great progress during my first year academic training, I find that I am more interested in Business Administration. Now I am writing to you to formally request to switch to this area of study.

The main reason for my decision is that the major I am studying in is my parents' choice. They insisted that I should study what they had learned before but after a year's study I have come to realize this is not the career I want to pursue in my future life. Besides, I have attended business classes as my optional course and achieved a good success, which further confirms my decision.

I am sorry for any inconvenience or trouble that might have been caused by this change. The decision is not made lightly. I do appreciate your kind consideration and sincerely hope you will grant me the shift to the new department.

Yours sincerely

Zhang Ming
