写一封英语的教师节感谢信

特别熟悉,不怎么样无聊,应该准确有｀｀

Dear teacher:
I am very pleased for you to teach me so careful.I bless you happy Teachers'Day.Last year,my mark was poor.And I was sad for it.It was you,my dear teacher helped me when I was in trouble.You helped me going over my lessons.Then I made my mind to study hard.With one year's hard working,I make progress,and get good marks in this term.I must thank you for your careful teaching.
