介利是个“笨男孩”,他的学习成绩很差。数学课，老师问他，二分之一与三分之一，哪个大？介利想了半天，说三分之一大。他想，三肯定比二大。结果引起全班同学哄堂大笑。常识课与自然课则更糟。气得老师一个星期往介利家里打几次电话，叫介利父母把介利带回家去，读书对他来说 Jerry is a “stupid boy” and his academic performance is poor. In math class, the teacher asked him, one-half and one-third, which one is bigger? Jangli thought for a long time, saying that one-third is big. He thought that the three must be greater than the second. As a result, the entire class laughed loudly. Common sense and nature classes are even worse. Qi Deyi made several phone calls to Jie Li’s home one week and asked his parents to take home his interest.
