One possible version:
Dear Sir,
My name is Li Hua, from Guang Ming High School in Beijing, China. I would like to opply for admission to the English Dept of your school.
I am a seventeen-year-old boy, and now in senior grade 3. I am sociable, easy-going, and good at communicating with others. I have made many friends and I can work well in a team. Meanwhile, I am quite independent and it is easy for me to adapt to a new environment.
As a senior student, I have been working hard at my lessons and have managed to get fairly high grades. I am sure that I shall graduate at the top of my class. I am especially good at English, and have won the first prize in an English Speech Contest. All this will enable me to continue my studies in your department without having much trouble with a language barrier. Therefore, I believe English is a good major for me.
I should he grateful if you can take my application into consideration.
Looking forward to your early reply.
Yours sincerely,
Li Hua
