It was the last day of the final examination in a university. A group of students entered the classroom happily. This was their last exam. They knew it wouldbe easy. The professor had said that they could bring any book or note they wanted. The only requirement(要求) was that they couldn’t talk with each other. The professor handed out the papers. They were glad to find there were only five questions. Three hours passed. The professor asked, "How many of you have finished all the five questions?" None of the students answered."How many of 3’ou have finished four?" No answers again."Thee? Two?" The students moved restlessly (不安地) in their seats."One, then? Certainly somebody has finished one." But the class remained silent."That is exactly what I expected," the professor said. "I just want to teach you a lesson--although you have completed four years of study, there are still manythings you don’t know about." Then be added, "You will all pass the exam, But remember: even though you are graduating from college, your education has just begun."【小题1】During the exam, the students could __ A. not take their notes B. ask others for help C. not talk with each other D ask the professor for help【小题2】How many students passed the exam at last?A．None of them.B．Only one.C．Half of them.D．All of them.【小题3】What can we learn from the passage?
