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 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 thinks 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.
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

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

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.

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.

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.

Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.
David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.
Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds’ health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.
He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."
And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."
Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.
However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.
According to Dr Dominoni's study, what cause robins to sing so much?

A．The breeding season.

B．The light in modern life

C．The dangerous environment.

D．The noise from heavy machinery.

What is the researchers' concern over the increase of birds' song output?

A．The environment might be polluted.

B．The birds' health might be damaged.

C．The industry cost might be increased.

D．The people's hearing might be affected.

What does the underlined word "nocturnal" in Paragraph 5 mean?

A．Active at night.	B．Inactive at night.
C．Active during the day.	D．Inactive during the day.

Why do some birds thrive in noisy environments?

A．Because there are fewer dangers.

B．Because there is more food to eat.

C．Because there is less light pollution

D．Because there are more places to take shelter.

Across Britain, burnt toast will be served to mothers in bed this morning as older sons and daughters rush to deliver their supermarket bunches of flowers, But, according to a new study, we should be placing a higher value on motherhood all year.
Mothers have long known that their home workload was just as heavy as paid work. Now, the new study has shown that if they were paid for their parental labours, they would earn as much as＄172,000 a year.
The study looked at the range of jobs mothers do, as well as the hours they are working, to determine the figure. This would make their yearly income ￡30,000 more than the Prime Minister earns.
By analysing the numbers, it found the average mother works 119 hours a week,40 of which would usually be paid at a standard rate and 79 hours as overtime. After questioning 1,000 mothers with children under 18,it found that ,on most days, mums started their routine work at 7am and finished at around 11pm.
To calculate just how much mothers would earn from that labour, it suggested some of the roles that mums could take on, including housekeeper, part-time lawyer, personal trainer and entertainer. Being a part-time lawyer, at ￡48.98 an hour, would prove to be the most profitable of the “mum jobs”,with psychologist（心理学家）a close second.
It also asked mothers about the challenges they face, with 80 percent making emotional（情感的） demand as the hardest thing about motherhood.
Over a third of mums felt they needed more training and around half said they missed going out with friends.
The study shows mothers matter all year long and not just on Mother’s Day. The emotional ,physical and mental energy mothers devote to their children can be never-ending, but children are also sources of great joy and happiness. Investing（投入）in time for parenting and raising relationships is money well spent.
How much would a mother earn a year if working as the Prime Minister?

A．￡30,000.	B．￡142,000.
C．￡172,000.	D．￡202,000.

The biggest challenge for most mothers is from.

A．emotional demand	B．low pay for work
C．heavy workload	D．lack of training

What is stressed in the last paragraph?

A．Mothers’importance shows in family all year long.

B．The sacrifices mothers make are huge but worthwhile.

C．Mothers’devotion to children can hardly be calculated.

D．Investing time in parenting would bring a financial return.

What can we conclude from the study?

A．Mothers’working hours should be largely reduced.

B．Mothers should balance their time for work and rest.

C．Mothers’labour is of a higher value than it is realised.

D．Mothers should be freed from housework for social life.

Nothing could stop Dad. After he was put on disability for a bad back, he bought a small farm in the country, just enough to grow food for the family. He planted vegetables, fruit trees and even kept bees for honey.
And every week he cleaned Old Man McColgin's chicken house in exchange for manure(肥料). The Smell really burned the inside of your nose. When we complained about the terrible smell, Dad said the stronger the manure, the healthier the crops, and he was right. For example, just one of his cantaloupes filled the entire house with its sweet smell, and the taste was even sweeter.
As the vegetables started coming in, Dad threw himself into cooking. One day, armed with a basket of vegetables, he announced he was going to make stew(炖菜).Dad pulled out a pressure cooker and filled it up with cabbages, eggplants, potatoes, corns, onions and carrots. For about half an hour. the pressure built and the vegetables cooked. Finally, Dad turned off the stove, the pot began to cool and the pressure relief valve sprayed out a cloud of steam. If we thought Dad's pile of chicken manure was bad, this was 10 times worse. When Dad took off the lid, the smell nearly knocked us out.
Dad carried the pot out and we opened doors and windows to air out the house. Just how bad was it? The neighbors came out of their houses to see if we had a gas leak!
Determined, Dad filled our plates with steaming stew and passed them around. It didn’t look that bad, and after the first wave had shut down my ability to smell, it didn’t offend the nose so much, either. I took a taste. It would never win a prize in a cooking competition, but it was surprisingly edible and we drank up every last drop of soup.
Why did Dad clean Old Man Mocolgin’s chicken house regularly?

A．To earn some money for the family.

B．To collect manure for his crops.

C．To get rid of the terrible smell.

D．To set a good example to us.

What can we infer about Dad’s stew?

A．It is popular among the neighbors.

B．It contains honey and vegetables.

C．It looks very wonderful.

D．It tastes quite delicious.

What does the underlined word “offend” in the last paragraph mean?

A．To attract	B．To upset
C．To air	D．To shut

What can we learn about Dad form the text?

A．He is an experienced cook.

B．He is a troublesome father.

C．He has a positive attitude to life.

D．He suffers a lot from his disability.
