　 Donald was not very good at maths. He could not understand the teacher’s explanations(解释). Ever when the teacher explained something a second time, Donald still could not understand it. “Never mind,” Donald told himself. “I’m quite good at other subjects. I’ll cheat(作弊)in the maths exam, then I won’t be in trouble.”

　 “I’ll sit next to the boy who’s best at maths,” he thought, “and copy down his answers.” The day of the exam came, and Donald sat next to Brian Smith, who always was at the top of the class in maths. Donald carefully copied Brian’s answers onto his own exam paper. At the end of the exam, the teacher collected the papers and graded(批改) them. Then she said, “Well, boys and girls. I’ve decided to give a prize to the student who got the highest grade. It’s difficult for me to decide who to give the prize to, however, because two students, Doanld and Brian, got the same grade.”

　 “Let them share it,” one of the other students said.

“I’ve thought about that,” the teacher said, “but I’ve decided to give the prize to Brian.” Donald was angry when he heard this. He stood up and said. “That’s not fair. I got the same grade as Brian.” “That’s true,” the teacher said. “However, Brian’s answer to Question 18 was ‘I don’t know,’ your was ‘Neither do I.’”

Finding enough meat was a problem for primitive (原始的) man and, keeping it for times when it was scarce(缺乏的) was just as hard. Three ways were found to keep meat from spoiling (腐烂.) : salting ( 盐) , drying, and freezing.

People near salty waters salted their meat. At first they probably put dry salt on it, but this kept only the outside. Later they may have pickled (腌) their meat by putting it in salt water.

In hot, dry places, men found that they could eat meat that had dried while it was still on the bones (骨头) .They later learned to cut meat into thin pieces and put it up to dry in the hot air.

Men in cold places found that frozen (结冰的) meat didn't spoil. They could leave their meat outside and eat it when they pleased.
