It was the last day of the final examination in a large eastern university. On the steps of one building, a group of students were talking about the exam   36 to begin in a few minutes. On their faces was   37 .This was their last exam—then on to graduation and jobs.
Some talked of jobs they already had, others talked of jobs they would get. With the certainty of four years of college, they felt  38 and able to take   39  of the world.
The coming exam, they knew, would be a(n)  40 task, as the professor had said they could bringeither books or notes they wanted, requesting, only  41 that they did not talk to each other during the test.
  42 they entered the classroom. The professor passed out the papers. And smiles appeared on the students’ faces as they   43  there were only five questions.
Three hours had passed before the professor began to  44 the papers. The students no longer looked confident. On their faces was a frightened expression. Papers in hand, no one spoke as the professor  45  the class.
He looked at the worried faces before him, and then asked: “How many completed all five questions?”   46 a hand was raised.
“How many answered four?” Still no hands.
“Three? Two?” The students  47 restlessly(不安地) in their seats.

These questions you couldn’t answer are relatively common in everyday  52 .” Then smiling, he   53 , “You will all pass this course, but remember—even though you are now college graduates, your education has just  54 .”
The years have  55  the name of the professor, but not the lesson he taught.
