一天，教授正在给学生们监考。他发下试卷，然后回到讲台前等待。
A professor was giving a big test one day to his students. He handed out all of the tests and went back to his desk to wait.
考试结束了，学生们纷纷交回试卷。教授发现一张试卷上别着一张百元钞票，还有一张纸条写着："一分一块钱。"
Once the test was over the students all handed the tests back in. The professor noticed that one of the students had attached a $100 bill to his test with a note saying "A dollar per point."
第二堂课，教授把试卷都发回学生们手中。其中一个学生不但得到了试卷还得到64块钱的找零。
The next class the professor handed the tests back out. This student got back his test and $64 change.
