My name is Zhang Meng and I'm a senior 3 student from China．Now I'm writing to express my thanks to you on behalf of my school and myself．
I have been studying as an exchange student in your school for a month．The past month has been a wonderful time，during which I have made many friends and learned a lot about American culture．Not only my spoken English，but also my ability to live independently has been improved a lot．
Thanks for your treatment and the service you offered us．And since this activity was completely a success，our school hopes to hold such activities more often in the future．
Finally，we warmly welcome you and your students to visit our school．I would be very glad to be your guide at that time．
Best wishes．
