急求，给老师写一封信，用英语

关于什么的啊
Dear teacher,
How are you?I'm your student. Thank you for your present.You send me such a helpful English dictionary.As soon as I got the dictionary,I started to read it.
In the past,my classmates often laughed at me when I read English, because my pronunciation was poor and I often made mistakes.Now if I'm not sure how to pronounce a word,I can look it up in the dictionary.
Best wishes.
Yours,
