問題詳情：

Last week, our class was   41  duty in the cafeteria for student self-management. On the first day, I   42   (shock) to see so much leftover food thrown away by students. What a waste! Being concerned about it, my classmates and I had a   43   (heat) discussion on how  44   (solve) the problem. Lots of good ideas came up, such as holding class meetings, putting up wall newspapers and charging a fine for wasting food. Finally, we all agreed that wall newspaper would be   45  (good) choice.

The next day, we put our idea into reality. Towards lunch time, we put up a wall newspaper outside the school cafeteria,   46   (call) on students not to waste food. Many students gathered around to read and   47   (express) their support. To my great delight, there were changes soon. In the cafeteria, I found the trays returned after lunch all empty   48   any leftover. Food 49  (save) and the dining hall was cleaner. Seeing this, I felt relieved and proud of   50  we had done.
