I'm writing to you about my gratitude for your having brought me up and my future plan.
I celebrated my 18th birthday last month,which means that I have been already an adult.I am so grateful to you that I don't know how to express it.First,thank you for providing me with good living environment.Second,when I meet with difficulties,you always give me encouragement and good advice.Besides these,you are always teaching me how to become a good man.
Now,I am a senior there students.The most important thing that I am facing is the national college entrance examinations.I am determined to try my best to pass the competitive exams.I believe I can enter my ideal key university through my efforts.
On the other hand, I want to be an independent man.With the development of this society,I will face a more competitive society in the future,so I will develop myself and make good preparations for it.
Yours sincerely.
