Dear John，
Last summer I take a part-time job in the International Camp for children. I have been told one more worker will be needed this year and I think you are fit 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, which is very exciting. They usually work only five hour a day, so we will have plenty of spare time to visit the area and have a fun, I am sure it will be an unforgettable experience. If you are interested in it, reply to me soon.
