Many students are not satisfied with the canteen in their schools, so they order the fast-food outside the campus. But the problem comes, some of them feel sick after eating fast-food, so the schools have taken some action to forbid students to order fast-food. A lot of students complain about the right to choose food. Our principal hear students’ voice, he had promised to improve the food choices and make students eat better. A semester passed, the principal had kept his words, a new canteen was built and students were happy to see the new food. Students can make better food choice, there are many delicious food that they have never met before. Now , students no longer go out to eat, they love the food in canteen. This is a win-win situation, students give up complaining and speak highly of their principal. 
许多学生不满意学校的食堂,所以他们预定校园外的快餐。但问题来了,有些人吃快餐后感觉不舒服,所以学校已经采取了一些行动,禁止学生订购快餐。很多学生抱怨选择食物的权力。我们的校长听到学生的声音,他承诺改善食物的菜式,让学生吃得更好。一个学期过去了,校长遵守承诺,一个新的食堂建成了，学生乐于看到新的菜谱。学生可以更好的选择食物,有很多美味的样式,他们从来没有见过。现在,学生不再出去吃饭,他们喜欢食堂的食物。这是一个双赢的局面,学生放弃抱怨,赞扬他们的校长。
