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!”
有個年輕的大學生，他不滿意自己所上的大學和所學的專業，於是便自暴自棄。他每天喝酒、逃課、不學習。就這樣，他變得越來越消沉。
但是，他從來都不會逃楊教授的生物課，因為他喜歡這門課。另外，楊教授講課生動有趣，他總是能夠全身心地聽講，不管班裏其他同學是否在認真聽。
