A young college student, reluctant that he was admitted to a wrong specialty of an undesirable college, abandoned himself to laxity-playing truant and given to drinking instead of studying. Thus he was becoming more and more demoralized.
But he was never absent from Prof. Yang's biology class. He liked the course. Beside, Yang's class was so vivid and interesting that he was always attentive to it regardless of other students paying attention or not in class.
Once he enclosed a note in the homework he handed in, saying,“Professor, it is said that today's college students are cheaper than potatoes. Do you agree?”
He didn't know why he took the action. It might be attributed to his trust to the professor, or because he did not want to carry on his depression and tried in vain to find a way out.
That day Prof. Yang sent for him after class. When he came he found the professor at the table on which were four dishes and one soup. They drank heartily over the dishes. When they became half drunk, the professor produced a small bluish potato that was sprouting and said to the young man,“Do you know how much it costs? It's skinny and lacks flesh. Moreover, it is poisonous. Nobody will take it even if it's given free of charge.”He tossed it into the rubbish bin.
The professor then showed him another potato that must weigh more than 500g.“This potato cultivated with organic fertilizer is not only large and fresh but also free of pollution. It costs 12-odd yuan(RMB) per kilogram.”
The young man was struck dumb by what he'd heard. The professor put the big potato into his hand and said,“Be such a potato. Don't forget there are potatoes and potatoes!”
有个年轻的大学生，他不满意自己所上的大学和所学的专业，于是便自暴自弃。他每天喝酒、逃课、不学习。就这样，他变得越来越消沉。
但是，他从来都不会逃杨教授的生物课，因为他喜欢这门课。另外，杨教授讲课生动有趣，他总是能够全身心地听讲，不管班里其他同学是否在认真听。
