问用英文写一个告别信留言

Dear Mr. Smith:- How are you! It’s a pity that I’m leaving this school soon. At this moment, I want to say :” Thank you!” You have taught us for three years. I think you are a good teacher. You regard us as your own children and take good care of us. Though you often get angry with us , I think you just want us to be better.I still remember it clearly. It was my first time to learn English. You told us that learning English is not easy. Some days later, I failed in an exam. I didn’t want to learn English any more. I almost wanted to give it up. You encouraged me to keeping learning and said:” Nothing is hard if you want to do it.” Thanks to your words, I began to learn it again and I made my mind up to learn it well.I will leave the school in a few days. I want to stay with you , but it’s impossible. I want you to know that I have learnt many things from you these years ,not only knowledge but also the sprite. Thank you!
