I'd like to express my sincere appreciation to you for your kindness and selflessly help.
It had been a month since I came to this beautiful school. You offered me so much help the first day when I met you in the school. Because your warm help and useful pieces of advice I have got use to the new school life so soon. However, I find it difficult to make the more friends who native language is English. In add, I still have difficulty in speak to my foreign teachers freely. Therefore, I hope you can recommend a club for me to joining so that I can improve my English.
Again, I'd like to express my thank to you, and look forward to your early reply.
