写一篇欢送外籍教师的英语作文假设你是李华,班级要举行欢送会欢送外籍教师Webslin,要点如下：两个月来你在老师的帮助下

Dear Webslin,
How are you doing? It has been two months since you first came to our school. With your help, I made rapid progress in my English study. Learning that you are leaving our school to attend your graduation test, we all feel sorry about.
Here I'd like to express my appreciation of your help as well as your patience. Moreover, we will never forget the time that we spent together in the English corner. I have made up my mind to contribute to the society in the future just as you did to us. I hope that you can do well in the exam and find a new job as early as possible. My friends and I have prepared a souvenir for you. Please come and visit us whenever possible,
Yours,
Li Hua
