图书馆里，一名学生正为微积分证明抓头流汗，此时，扫地大妈从身边走过，小声地说，“用拉格朗日中值定理试试”，随后飘然而去，该同学豁然开朗。

library,A student is for calculus proof catch head sweat,At this time,Sweep the floor aunt from the side walk,whispered,"Using Lagrange's mean value theorem to try",Then float however go to,The students be suddenly enlightened.

　　这则网络段子让人会心一笑。在中南林业科技大学的图书馆里，当学生面对高数题无从下手时，也有一名“老师”主动上前解答，现在已有6年时间。同学们不知其身份，只亲切地叫他“古教授”。1月9日下午，记者联系上“古教授”。接下来的事情却让记者大跌眼镜“古教授”说，自己并不是教授，只是一名保洁员。

This is the network you'd let a person understanding laugh.In the central south forestry university of science and technology in the library,When students face high number problem when do not know how to start,Also have a"The teacher"Active to answer,Now there have been six years.The students don't know its identity,Only affectionately call him"The professor".On January 9th afternoon,Reporters on the contact"The professor".The next thing lets reporter levels"The professor"said,He was not a professor,Just a cleaner.

学生：“神秘教授”来图书馆义务辅导 students:"Mysterious professor"To the library obligation guidance

　　拍下“古教授”辅导学生场景的，是中南林科大材料科学与工程学院的学生陈乐。陈乐说，高数很容易挂科，有了“古教授”帮忙，考试就不会那么担心了，“老教授身上的正能量让我们感动。”

take"The professor"Students of the scene,Central south university is Lin of materials science and engineering college students ChenLe.ChenLe said,High number easily hanged division,the"The professor"help,It won't be so worried about the exam,"The old professor on the positive energy let us be moved."

　　1月9日上午，记者来到了中南林业科技大学图书馆，发现不少自习的学生都知道这个辅导高数的“古教授”。中南林业科技大学旅游学院大一的曹同学说，自己认识“古教授”不到半年，但从学姐学长口中得知，这位神秘的“老教授”来图书馆义务辅导已经好几年，“很多人都受过古老师的帮助。”曹同学介绍，“古教授”一般会在星期二、星期六、星期日的晚上到图书馆的自习室来，看到谁桌上放着高数书就会主动过去教，一直到晚上10点图书馆闭馆才离开。“古教授”还留下了电话，只要有问题打电话给他，他都会过来，“昨天我们班有同学打电话求助，他马上就赶到图书馆来了。”

On January 9th morning,Reporters came to zhongnan forestry university of science and technology library,Find a lot of self-study students know the guidance of high number"The professor".Central south university of science and technology of forestry tourism college freshman students of cao said,Yourself know"The professor"Less than half a year,But from the senior sister heard,The mysterious"The old professor"To the library obligation guidance has for several years,"A lot of people with ancient the teacher's help."Cao introduce the,"The professor"General meeting on Tuesday/On Saturday/On Sunday evening to the library to study room,See who the table high number book will be active in the past to teach,Until ten o 'clock at night closed library didn't leave."The professor"Also left telephone,As long as there is problem to call him,He will come,"Students in our class yesterday called for help,He'll get to the library."

“古教授”：其实我是一名保洁员 "The professor":In fact I'm a cleaner

　　关于“古教授”的身份，同学们都不清楚。1月9日下午，记者电话联系上了“古教授”。还没等记者开口，他便答道，“今晚7点半，我会来学校。”当记者问他是否为学校的退休教授时，他却告诉记者，自己在湖南省地质矿产勘查开发局四二队工作，“是一名保洁员。”

about"The professor"identity,The students are not clear.On January 9th afternoon,Reporters on the telephone"The professor".Before reporters open,And he answered,"Tonight at half past seven,I will come to school."When a reporter asked him if he is emeritus professor of the school when,But he told reporters,In hunan province geological mineral exploration development authority 42 team work,"Is a cleaner."

　　他介绍，他叫古棱峰，今年55岁，1981年毕业于怀化师范高等专科学校(现怀化学院)数学教育专业，1981年至1985年从事数学教学工作。然而，后来因为个人原因，他离开了教学岗位。

He introduced,His name is ancient edge peak,55 years old this year,In 1981, he graduated from HuaiHua teachers college(Now HuaiHua college)Mathematics education professional,From 1981 to 1985 in mathematics teaching work.however,But for personal reasons,He left the teaching post.

　　“其实我一直都想去教大学。”古棱峰说，自己很喜欢从事高等数学的教学与研究，后来还利用空闲时间去湖南师大理学院与同学交流。2006年，他搬至中南林科大附近，便来此义务辅导学生，到现在已有6年。古棱峰说，自己喜欢学校的氛围，还经常去音乐系的琴房弹钢琴。

"Actually I've always wanted to go to university teaching."Ancient edge peak said,They are like engaged in higher mathematics teaching and research,Then use idle time to hunan normal university college of science and classmates.In 2006,,He moved to south forest near university,They have come to this obligation counseling students,Now almost six years.Ancient edge peak said,They like the atmosphere of the school,Also often go to the department of music of piano room to play the piano.

　　记者一直以为古棱峰自称保洁员是因为看了网络段子在开玩笑，再三向其确认。随后，记者在湖南省地质矿产勘查开发局四二队网站上，发现一篇标题为《我的承诺》的文章，署名为古棱峰：“我庄严承诺：在公共卫生保洁工作上，保证天天按质量打扫一栋卫生区，拖楼道、擦电梯，洗垃圾桶和垃圾站……”

Reporters have been thought ancient edge peak claims to protect a jie member is because see the network joke kidding,Over and over again to confirm it.then,Reporter in hunan province geological mineral exploration development authority 42 team website,Find an article entitled[I promise]article,The ancient edge peak:"I solemnly promise:In public health cleaning work,Ensure the quality of every day to clean the house health area,Tow corridor/Wipe the elevator,Wash the trash and also..."

图书馆奇遇这位解题高手 Library adventure the problem player

　　回忆起第一次碰到古老师，曹同学至今还觉得很“神奇”：“当时我坐自习室门口位置，桌上摊着《经济数学微积分》的书，正对着‘求不定积分’的作业题发愁。”她发现，旁边桌子上，有老师正在辅导别的同学。让她惊喜的是，那个老师给同学讲解完题后，转过来对她说：“同学，你有什么问题吗？我可以帮你解决。”曹同学非常感谢古老师提供的帮助：“他很有耐心，不懂的地方会细细分析，那一章的内容在他的讲解下变得很容易。”

Remember the first time you meet the teacher,Cao students still feel very"magic":"At that time I sat at the door of the study room position,The table stands the[Economic mathematics calculus]book,Opposite the‘For indefinite integral’Operations that worry of."She found,Beside the table,A teacher is coaching other students.Let her surprise,The teacher to students after the interpretation problem,Turn to say to her:"students,Do you have any questions?Can I help you solve."Cao students thank you very much for the teacher to provide help:"He is patient,Don't understand the place will be careful analysis,The chapter content in his lecture next become very easy."

　　另一个周同学则讲了这样的传说：一个备战考研的师姐想请古老师指导复习矩阵知识，结果古教授从最基础的概念开始讲起，把相关的知识点系统地梳理了一遍，“从晚上8点多讲到10点多，还附带讲了近几年的考研真题，把师姐都感动得哭了。”

Another week the students speak such a legend:A preparation for one's deceased father grind of the teacher elder sister want to please the teacher guidance review matrix knowledge,The results from the most ancient professor based concept to start with,The related knowledge systematically comb again,"From the night more than eight about ten o 'clock,Attached is about the world in recent years, one's deceased father grind,The sisters are was moved to tears."
