No one is sure how the ancient Egyptians built the pyramids near Cairo. But a new study suggests they used a little rock‘n’roll. Long-ago builders could have attached wooden poles to the stones and rolled them across the sand, the scientists say.
“Technically, I think what they’re proposing is possible,” physicist Daniel Bonn said.
People have long puzzled over how the Egyptians moved such huge rocks. And there’s no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.
The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect wokers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.
Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.
However , physicist Joseph West think there might have been a simpler way , who led the new study . West said , “I was inspired while watching a television program showing how sleds might have helped with pyramid construction . I thought , “Why don’t they just try rolling the things ? ” A square could be turned into a rough sort of wheel by attaching wooden poles to its sides , he realized . That , he notes , should make a block of stone “a lot easier to roll than a square”.
So he tried it.
He and his students tied some poles to each of four sides of a 30-kilogram stone block.That action turned the block into somewhat a wheel.Then they placed the block on the ground.
They wrapped one end of a rope around the block and pulled.The researchers found they could easily roll the block along different kinds of paths.They calculated that rolling the block required about as much force as moving it along a slippery(滑的)path.
West hasn’t tested his idea on larger blocks,but he thinks rolling has clear advantages over sliding.At least,workers wouldn’t have needed to carry cattle fat or water to smooth the paths.
1.It’s widely believed that the stone blocks were moved to the pyramid site by ______.
A.rolling them on roads
B.pushing them over the sand
C. dragging them on some poles
D. sliding them on smooth paths
2.What does the underlined word “it”in Paragraph 7 refer to?
A. rolling the blocks with fat.
B.Rolling the blocks on wooden wheels.
C.Rolling poles to move the blocks.
D. Rolling the blocks with poles attached.
3.Why is rolling better than sliding according to West ?
A. Because more force is needed for sliding.
B. Because less preparation on path is needed for rolling.
C. Because sliding on smooth road is more dangerous.
D. Because rolling work can be done by fewer cattle.
4.What is the text mainly about ?
A. An experiment on ways of moving blocks to the pyramid site.
B. An argument about different methods of moving blocks to the pyramid site.
C. An application of the method of moving blocks to the pyramid site.
D. An introduction to a possible new way of moving blocks to the pyramid site.

No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.
Let’s take a man we’ll call Mr. Fielder, for example. He did everything connected with farming. He planted seeds, tended the fields, and harvested and sold his crops. At the same time, he did many other jobs on the farm. However, he didn’t make the bricks for his house, cut his trees into boards, make the plows (犁), or any of other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.
Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in making really good plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows.
How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows.
Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay, or wood symbols for the products they had for sale.
A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people’s attention.
A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such a person to spread the news about their products. Often this earliest form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today’s world.
1.What probably led to the start of advertisement?
A. The discovery of iron.
B. The specialization of labor.
C. The appearance of new jobs.
D. The development of farming techniques.
2.The writer makes up the two stories of Mr. Fielder and Mr. Plowright in order to __________.
A. explain the origin of advertising
B. predict the future of advertising
C. expose problems in advertising
D. provide suggestions for advertising
3.The last two paragraphs are mainly about __________.
A. the history of advertising
B. the benefits of advertising
C. the early forms of advertising
D. the basic design of advertising

The right to pursue happiness is issued to us all with our birth, but no one seems quite sure what it is.
A holy man in India may think that happiness is in himself. It is in needing nothing from outside himself. If wanting nothing, he lacks nothing. We westerners, however, are taught that the more we have from outside ourselves, the happier we will be, and then we are made to want. We are even told it is our duty to want. Advertising, one of our major industries, exists not to satisfy these desires but to create them---and to create them faster than any man’s money in his pocket can satisfy them. Here, obviously someone is trying to buy the dream of happiness and spending millions upon millions every year in the attempt. Clearly the happiness-market is not running out of customers.
I doubt the holy man’s idea of happiness, and I doubt the dreams of the happiness-market, too. Whatever happiness may be, I believe, it is neither in having nothing nor in having more, but in changing --- in changing the world and mankind into pure states.
To change is to make efforts to deal with difficulties. As Yeats, a great Irish poet once put it, happiness we get for a lifetime depends on how high we choose our difficulties.
It is easy to understand. We even demand difficulty for the fun in our games. We demand it because without difficulty there can be no game. And a game is a way of making something hard for the fun of it. The rules of the game are man-made difficulties. When the player ruins the fun, he always does so by refusing to play by the roles. It is easier to win at chess if you are free, at your pleasure, to cast away all the rules, but the fun is in winning within the rules.
The same is true to happiness. The buyers and sellers at the happiness-market seem to have lost their sense of the pleasure of difficulty. Heaven knows what they are playing, but it seems a dull game. And the Indian holy man seems dull to us, I suppose, because he seems to be refusing to play anything at all.
The western weakness may be in the dreams that happiness can be bought while eastern weakness may be in the idea that there is such a thing as perfect happiness in man himself. Both of them forget a basic fact: no difficulty, no happiness.
1.Who shares the same idea of happiness with the author?
A. The Indian holy man B. The great Irish poet Yeats
C. Advertisers D. The buyers and sellers at the happiness-market
2.What does “happiness-market” mean in the second paragraph?
A. It means a place in which people can buy things happily
B. It means a market which lacks happy customers
C. It means a pure state for the world and mankind
D. It means a market where people try to buy happiness with money.
3.According to the passage, which of the following is Right?
A. The Indian holy man is much happier than westerner.
B. The westerners understand happiness better than the Indian holy man.
C. There is no fun without playing by the rules
D. Both the eastern weakness and western weakness are the same.
