Once he put a note in the homework he handed in, saying: “Professor, it is said that today’s college students are c  5   than potatoes. Do you agree?”
That day Professor Yang sent for him after class. When he came, he f  6  the professor at a table with food on it. They drank happily over their meal.
When they became half drunk, the professor took out a small potato that was sprouting (发芽的). “Do you know how much this c  7 ?” he asked the young man. “It’s soft but poisonous. N  8  will take it even if it’s free. ” He then threw the potato away.
The professor then showed him another potato. It was half the s  9  of a football and perfectly round. “This potato is organic (有机的). It is not only large and fresh but also free of pollution. People are in need of such k  10   of potatoes and they’re quite expensive.”
The young man was impressed by what he’d heard. “Be such a potato,” said the professor.
