Passage Two

　　The oldest stone building in the world are the pyramids.

　　They have stood for nearly 5,000 years,and it seems likely that they will continue to stand for thousands of years yet.

　　There are over eighty of them scattered along the banks of the Nile,

　　some of which are different in shape from the true pyramids.

　　The most famous of these are the "Stop "pyramid and the "Both"pyramid.

　　Some of the pyramids still look much as they must have done when they were built thousands of years ago.

　　Most of the damage suffered by the others has been at the hands of men who were looking for treasure or,

　　more often,for stone to use in modern buildings.

　　The dry climate of Egypt has helped to preserve the pyramids,and their very shape has made them less likely to fall into ruin.

　　These are good reasons why they can still be seen today,

　　but perhaps the most important is that they were planned to last for ever.

　　It is practically certain that plans were made for the building of the pyramids because the plans of other large works have fortunately been preserved.

　　However,there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves.

　　Consequently,we are only able to guess at the methods used.

　　Nevertheless,by examining the actual pyramids and various tools which have been found,

　　archaeologists have formed a fairly clear picture of them.

　　Questions 14 to 16 are based on the passage you have just heard.

　　14.Why do some pyramids remain well preserved?

　　15.What has caused the most damage to the pyramids?

　　16.Why do we have a clear picture of how pyramids were built?

　　Passage Three

　　Many primitive peoples believed that by eating an animal they could get some of the good qualities of that animal for themselves.

　　They thought,for example,that eating deer would make them run as fast as the deer.

　　Some primitive tribes believed that eating enemies that had shown bravery in battle would make them brave.

　　Man_eating may have started because people were eager to become as strong and brave as their enemies.

　　Among civilized people it was once thought that ginger root by some magical power could improve the memory.

　　Eggs were thought to make the voice pretty.

　　tomatoes also were believed to have magical powers.

　　They were called love apples and were supposed to make people who ate them fall in love.

　　Later another wrong idea about tomatoes grew up__the idea that they were poisonous.

　　How surprised the people who thought tomatoes poisonous would be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during World War II.

　　Even today there are a great many wrong ideas about food.

　　Some of them are very widespread.

　　Questions 17 to 20 are based on the passage you have just heard.

　　17.What does the passage seem to be talking about?

　　18.Why did some primitive tribes eat enemies according to the passage?

　　19.What was once thought to have magical power to improve memory?

　　20.What will the speaker probably talk about next?
