   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 pole s to the stones and rolled then 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 htere’s no obvious answer. On average, each of the two mollion big stones weighed about as much as a large pickup truck. The Egyptians smehow moved the stone blocks to the pyramid site from about one kilometer away.

    The most popular view is that Egyptian workes slid the blocks along smooth paths. Many scientists suspect wokers first would haveput 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. Resrarchers 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 , 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 woldn’t have needed to carry cattle fat or water to smooth the paths.

46.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.sliding them on smooth paths

    D.dragging them on some poles

47.The underlined part “lubricated the paths” in Paragraph 4 means____.

    A.made the path wet

    B.made the path hard

    C.made the path wide

    D.made the path slippery

48.What does the underlined word “it”in Paragraph 7 refer to?

    A.Rolling the blocks with poles attached.

    B.Rolling the blocks on wooden wheels.

C.Rolling poles to move the blocks.

D.rolling the blocks with fat.

49. Why is rolling better than sliding according to West ?

   A. Because more force is needed for sliding.

   B. Because rolling work can be done by fewer cattle.

   C. Because sliding on smooth road is more dangerous.

   D. Because less preparation on path is needed for rolling.

50. What is the text mainly about ?

   A. An experiment on ways of moving blocks to the pyramid site.

   B. An application of the method of moving blocks to the pyramid site.

   C. An argument about different methods of moving blocks to the pyramid site.

   D. An introduction to a possible new way of moving blocks to the pyramid site.

It was a hot summer day that found me running down the street with a dollar in my sweaty hand.The closer I got to Sam & Joe's Stationery Store, the more excited I was. After all, a dollar was a tidy sum for an 11-year-old boy in 1961.

Out of breath, I swung open the door and got a blast of cold air that instantly cooled me off. I was in a place of pure happiness. Sam & Joe's had it all一books, ca
