It was the final examination for physics at a school. The examination was two hours long, and exam papers were given. The teacher was very strict and told the class that any exam paper which was not on his desk in two hours would be refused（拒绝） and the student would fail（不及格）. A half hour into the exam, a student came rushing in and asked the teacher for an exam paper.

"You're not going to have time to finish this," the teacher said slowly as he gave the student a paper.

"Yes, I will," answered the student. He then took a seat and began writing. After two hours, the teacher began to call for the exam papers, and the students stood up and put them on the teacher’s desk, all except the late student, who went on writing. A half hour later, the last student came up to the teacher who was sitting at his desk and busy writing something. He tried to put his exam paper on the stack（摞）of the other papers already there.

"No, you can't, I'm not going to take that in. It's late."

The student became worried. He thought for a while, then he asked the teacher in a low voice," Do you know WHO I am?"

"No, surely I don't," answered the teacher.

"DO YOU KNOW WHO I AM?" The student asked again.

"No, and I don't care," said the teacher in a louder voice.

"Good," answered the student, who quickly put his paper in the middle of the stack of exam papers, and rushed out of the room.
