英文感谢信怎么写

dear mike，
    thank you very much for the english dictionary you sent me for my seventeenth birthday。 it's just what i need!
    my english spelling is very poor and i often make mistakes whenever i write， but now， thanks to your present， i can look up the words in the dictionary when i am not very sure about the spelling。
    i hope you are well and i look forward to seeing you in china next month。
    best wishes，
fu young
