用英语谢一封感谢信,内容大概是感谢Mr 杨六年的关怀与教育,自己会继续努力,不少于150个单词.

Dear teacher:
I really want to say thank to you because I have changed so much just because one sentence you said.I used to be a naughty boy/girl and not study hard.I thought you would punish me for my poor score,while you didn't.I was so touched by what you said that day and since then I changed my attitude,all because of your confidence with me and your encouragement to me!Thank you!
