| I felt sadly yesterday when our teacher told us something about Project Hope in class. It has set up to help the children in the countryside who can't pay to go to school. After school I came home. I was wondering if I could do something for the Project then I caught sight of money-collecting box on the table. Then I made up my minds to send my pocket money which I had saved for nearly one year for the children who wanted to go to school. I wrote a letter to him and hurried to the post office. Together with the letter I posted the money and sent with my best wishes to them. | 1._____ 2._____ 3._____ 4._____ 5._____ 6._____ 7._____ 8._____ 9._____ 10._____ |
