Dear Brown,

     Last summer I take a parttime job in the International Camp for children. I have been told one more

worker will be needed in this year and I think you are fit to it. How about join us? The camp is at the

foot of a small hill close to a river. It is so a beautiful place! We can hear birds singing happy all around.

Everybody sleeps in tents, that is very exciting. We usually work only five hours a day, so we will have

plenty of spare time visit the area and have a fun. I am sure it  will be an unforgettable experience. If you

have interests in it, reply to me soon.

                                                                                                                      Yours,

                                                                                                                       Li Hua
