寫比老師的英文信，求各英文高手幫忙

My Dear EnglishTeacher,
According to the curriculums, I would like to choose French as my second language of study in next semester. In the beginning, I had only chosen English for my study but now I wanted to learn French as well. It is my earnest hope that you will consider and grant me the request for enrollment in next semester. Thank you very much.
Yours Sincerely,
