9.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 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 workers 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.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,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.

46.It's widely believed that the stone blocks were moved to the pyramid site byC.
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 4meansD.
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 7refer to?A
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?D
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?D
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.

"Then let's make it."Waller went to the man's table and whispered to him,"Please tell your boss that the funny man Waller's hen gave birth to a baby."
    Three days later a letter reached Mr.Waller in which were$100 and a piece of yellow paper with the words,"Mr.Waller,you have succeeded-When I repeated your$100-worth sentence,my boss burst into frightening laughter,saying that whoever has managed to make him laugh during the business hours will get dismissed!"

2.Do you know how it is when you see someone yawn and you start yawning too?Or how hard it is to be among people laughing and not laugh yourself?Well,apparently it's because we have mirror neurons (神經(jīng)元)in our brains.
Put simply,the existence of mirror neurons suggests that every time we see someone else do something,our brains imitate (模仿)it,whether or not we actually perform the same action.This explains a great deal about how we learn to smile,talk,walk,dance or play sports.But the idea goes further:mirror neurons not only appear to explain physical actions,they also tell us that there is a biological basis for the way we understand other people.
Mirror neurons can undoubtedly be found all over our brains,but especially in the areas which relate to our ability to use languages,and to understand how other people feel.Researchers have found that mirror neurons relate strongly to language.A group of researchers discovered that if they gave people sentences to listen to (for example:"The hand took hold of the ball"),the same mirror neurons were triggered as when the action was actually performed (in this example,actually taking hold of a ball).
Any problems with mirror neurons may well result in problems with behavior.Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning.However,it is not yet known exactly how these discoveries might help find treatments for social disorders.
Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互動).Indeed,it may turn out to be the equivalent (相等物)for neuroscience of what Einstein's theory of relativity was for physics.And the next time you feel the urge to cough in the cinema when someone else does-well,perhaps you'll understand why.

67.Mirror neurons can explainC.
A.why we cry when we are hurt
B.why we cough when we suffer from a cold
C.why we smile when we see someone else smile
D.why we yawn when we see someone else stay up late
68.The underlined word"triggered"in the third paragraph probably means"A".
A.set off       B.cut off
C.built up      D.broken up
69.We can learn from the passage that mirror neuronsA.
A.relate to human behavior and interaction
B.control human physical actions and feelings
C.result in bad behavior and social disorders
D.determine our knowledge and language abilities
70.What is the passage mainly about?D.
A.Ways to find mirror neurons.
B.Problems of mirror neurons.
C.Existence of mirror neurons.
D.Functions of mirror neurons.
