1 对老师的问候 2大学的生活和学习与中学的不同 3你对未来学习生活的计划和安排Dear Teacher, How have you been lately? I am doing fine in college. I have much more freedom compared to my life during high school and I like college a lot. Although I miss you and my fellow high school classmates, college life is pretty good and I am doing well. In the near future, I think I will continue to learn as an education major. Later on, I think I want to be a teacher as well. What do you think? Do you think I will be a good teacher? Anyway, I look forward to your reply. Hope you are doing well! （英语作文）Sincerely, Student
