It was the last day of the final examination(考试)in a college. On the steps of building, a group of engineering students were waiting for the last exam. On their faces was confidence(自信).

They knew the exam would be easy. The professor(教授) had said they could bring any books or notes during the test.

Right after they came into the classroom. The professor handed out the papers. There were only five questions on it.

Three hours passed. Then the professor began to collect the papers. The students no longer looked confident. On their faces was nervous expression. The professor watched the worried faces before him, and then asked. “How many of you have completed all five questions?” No hand was raised. “How many of you have answered four?” Still no hands. “Three? Two?” The students moved restlessly in their seats. “One, then? Certainly somebody has finished one.” But the class kept silent(沉默). The professor said, “That is exactly what I expected(期盼). I just want to make you know clearly that even though you have completed four years of engineering, there are still many things about the subject you don’t know. These questions you could not answer are common in everyday practice.” Then, smiling, he added, “You will all pass this course, your education has just begun.”

The years have obscured the name of this professor, but not the lesson he taught.

It was the last day of final exams in a university. On the steps of one building, a group of engineering students were discussing the exam. On their faces was confidence . This was their last exam and then they would graduate. With all these four years of college behind them, they felt ready to go into the world.
The professor had said they could bring any book or note they wanted, but they could not talk to each other. They went into the classroom happily. The professor gave them the papers. They smiled when they found that there were only five questions.
Three hours passed and the professor began to collect the papers. The students no longer looked so confident . The professor faced the class. No one spoke. They just held papers in their hands.
The professor then asked, "How many of you finished all five questions?"
Not a hand was raised.
"How many answered four?"
Still no hand.
"Three? Two?"
The students looked worried in their seats.
"One, then?" Certainly somebody finished one.
However, nobody replied. The professor put down the papers. "That is just what I thought," he said. "I just want to tell you that, even though you have finished four years of engineering, there are still many things about the subject you don't know. These questions you could not answer are quite common in everyday practice." Then he added with a smile, “You will all pass this course, but remember——even though you are now college graduates, your education has just begun."
