It was the last day of the final examination in a large eastern university. On the steps of one building, a group of engineering seniors gathered, discussing the exam due to begin in a few     . On their faces was confidence（自信）. This was their last exam—then on to     and jobs.
Some talked of jobs they already had; others talked of jobs they     get. With the certainty of four years of college, they felt ready and able to take     of  the world.
The coming exam, they knew, would be a(n)              task. The professor had said they could bring           books or notes they wanted, requesting only that they did not          each other during the test.
they entered the classroom. The professor passed out the papers. And smiles       on the students’ faces as they noted there were only five essay-type questions.
Three hours had passed         the professor began to collect the papers. The students no longer looked confident. On their faces was a frightened expression. Papers in hand, no one spoke as the professor faced the class.
He looked at the         faces before him, and then asked, “How many completed all five questions?”         a hand was raised.
“How many answered four?” Still no hands.
“Three? Two?” The students moved restlessly in their seats.
“One, then? Certainly somebody finished        .” But the class remained silent.
The professor put down the papers. “That is exactly what I        ,” He said. “I just want to impress upon you that         you have completed four years of engineering, there are still many things about the           you don’t know. These questions you couldn’t answer are relatively          in everyday practice.” Then smiling, he added, “You will all        this course, but remember—even though you are now college graduates, your education has just        .”
Over years they have         the name of  his professor, but not the lesson he taught.
