多年以前,美国一个小镇的小学来了一位新老师。开学时老师向小朋友们宣布,这个学期谁的努力最大,对班级贡献最多,老师会亲自做一件“礼物”送给他。 Years ago, a new teacher came to primary school in a small town in the United States. At the beginning of the school, the teacher announced to the children that most of the students who worked hard in this semester would contribute the most to the class, and the teacher would personally give him a “gift”.
