Dick was a college student. He was studying history. But at the end of the first year he did not pass the exam. A month later he sat for the make-up(补考) exam, but he was down again. Dick was worried, because he knew he might have to leave the college.

When Dick’s father knew this, he went to see the professor. “Dick is a good boy,” said the father. “If you let him pass this time, I’m sure he will study harder next year and pass all exams with very good marks.”

“No, that’s quite impossible,” answered the professor. “He almost knows nothing about history. Last month I asked him when Napoleon（拿破仑） died, and he said he didn’t know.”

“Please, sir, give him another chance,” said the father. “Sometimes we were too busy to read the evening papers carefully, so we even didn’t know Mr Napoleon was ill.”
