 The next day many engineering students would take part in the final exam. They were discussing the exam on the playground. On their faces was confidence. After the exam，they would graduate. With the four years of college life, they were preparing for going into the world.

  The professor said they could take any book or note they wanted，but they couldn't talk with one another during the exam. So they thought the coming exam must be easy.

  The exam began. After the professor handed out the papers，the students were happy to find there were only five questions on it.

  Three hours later, the professor began to collect the papers. He couldn't find confidence from his students. Then he said, "The exam came to an end. Did all of you finish the five

questions?"

  No one answered. How many finished four? There were still no answers. "Three? Two? One?"

  The students looked more worried. The class still kept silent. " It's not only an exam but also our last class we have. The result is just what I expected，" the professor smiled and said. "I just want to tell you all that though you have finished four years of engineering, there are still many things you don't know. It's common that you couldn't answer these questions in practice. Now put down your pens, you will all pass this course. But please remember even if you graduate from the college soon，there is no end to learning.”
