Dear Sally，

Now I’d like to tell you something about my part-time job this summer vacation, of which I worked like a guide in a travel agency. The work was interesting but tired. I think it was helpful to work this holiday. It was the first time that I have earned money on my own. I’ve come to understand how hard my parents work to support for the family. I used to keep on ask them for money, but now I’ll never waste money and learn to share worry to my parents. I’ve learnt how to get along well with others. What’s worse, I’ve gained some working and social experience and I have learnt something can’t be learnt from textbooks. All these will be good for my future. In the word, I had a wonderful and valuable summer vacation.
