Dear teacher, At first, I'm happy to hear that you will be a mother. Please accept my heartiest congradulations! You are a good teacher for us, eapecially for me. I'm not good at English before, but with your help, I make much progress. Because of you, I have my own dream. I'm not a student who always likes playing any more. I can study hard for my dream. Thanks for giving me so much encouragement and help! I will never forget you! Wherever I am, I will remember the word you have said," Do a useful person in the future!" Best wishes for you! Look after youself and have a good rest .Don't be too tired! Yours, ****** 我自己写的，希望你可以采纳！谢谢！
