今天上数学课，张老师让我们做《数学练习册》。我心里想，做《数学练习册》实在是太简单了，就拿起铅笔飞快地做了起来。
Today, in math class, Mr. Zhang asked us to do the Math Workbook. I thought to myself that it was too easy to make the Math Workbook, so I picked up my pencil and started to do it quickly.
这题简单，心算就行了；这题数量关系很清楚嘛，不用画线段。不大功夫，就把作业做完了。我走马观花似的看了一遍就算检查完了，便高高兴兴地把《数学练习册》交给了老师。
This problem is simple, mental calculation is OK; the quantitative relation of this problem is very clear, do not draw line segment. Without much effort, I finished my homework. I went through it like a horse, and even after checking it, I happily handed over the Math Workbook to the teacher.
到了第二节课，老师来报分。老师把90分到99分的名单念了一遍。没有我我愣住了。但心里仍想着：会不会是老师念漏了呢？“林晨87分。”什么？我简直不敢相信自己的耳朵。我，一名班长，居然只得了87分？望望老师投来不解的、失望的眼神，想着下课同学们的嘲笑，泪水慢慢涌进了我的眼眶。
In the second class, the teacher reported the score. The teacher read the list from 90 to 99. I was stunned without me. But I still think: is it the teacher who missed it? "Lin Chen scored 87." What? I can't believe my ears. I, a monitor, got only 87 points? Looking at the teacher's puzzled and disappointed eyes, thinking of the laughter of the students after class, tears slowly poured into my eyes.
“我为什么考这么差？为什么不检查？” 这次练习让我终身难忘：骄傲自满是会吃亏的。我一定要记住这个教训。
