Paul had gone to the college to study history，but at the end of his first year，he failed in history examination，and he was told that he would have to leave the college.However，his father decided that he would go to see the professor to ask him to let Paul continue his studies the following year.
“He's a good boy，"said Paul's father，"and if you let him pass this time，I'm sure he'll improve（提高）a lot next year and pass the exami-
nations at the end of it really well."
"“No，no，that's quite impossible！"replied the professor immediately."Do you know，last month I asked him when Karl Marx had died，and he didn't know.""Please Sir，give him another chance，"said Paul's father."You see，we are poor and we don't take any newspapers or magazines in our house，so none of us even knows that Karl was ill."
