Who Built Giza's Pyramids（金字塔）?
1 .For centuries,the pyramids of Giza have been timeless symbols of Egyptian culture.But who actually built them? For years, we did not know for sure.But archeologists（考古学家）recently discovered an ancient village near the pyramids.Close by,there was also a ceme-tery（墓地）where pyramid builders were buried.From studying these places, archeologists can now confirm that the pyramids were not built by slaves or foreigners.Ordinary Egyptians built them.
2 .It took about eighty years to build the pyramids.According to archeologists,about 20,000～30,000 people were involved in completing the task.The workers had different roles.Some dug up the rock,some moved it,and some shaped it into blocks.People also worked on different teams,each with its own name.On a wall in Khufu's Great Pyramid,for example,a group of workers wrote“Friends of Khufu.”Teams often competed to do a job faster.
3.Life for these workers was hard.“We can see that in their skeletons（骨架）,”says Azza Mohamed Sarry El-Din,a scientist studying bodies found in the cemetery.The bones show signs of arthritis（关节炎）,which developed from carrying heavy things for a long time.Archeologists have also found many female skeletons in the village and cemetery.The damage to their bones is similar to the men's.Their lives may have been even tougher:male workers lived to age 40～45,but women to only 30～35.However,workers usually had enough food,and they also had medical care if they got sick or hurt.
4 .The work was challenging,but laborers were proud of their work.“It's because they were not just building the tomb of their king,” says Egyptian archeologist Zahi Hawass.“They were building Egypt.It was a national project,and everyone was a participant.”
The pyramids of Giza were built______.
A.of their king
B.from taking heavy things
C.on different teams
D.by foreigners
E.of their work
F.by ordinary Egyptians

[单选题]When it was built in 1721 beside the River Derwent,in Britain's East Midlands,Lombe's silk mill became something of a tourisl attraclion.Daniel Defoe,one of its many visitors,described its"vast bulk"as"a curiosity of a very extraordinary nature".Employing some 300 people,mostly children in ghastly conditions,the mill was nol large by modern sLandards.But it is widely regarded as the first successful mechanised factory,an innovafion that over the next 100 years transformed the way people lived and worked.Lombe's mill is the natural starting-point for Joshua Freeman's lively chronicle of the factory,which as the title of his book"Behemorth"implies,concentrates on the largesl specimens of cheir time.Mr Freeman,a historian at Queens College in New York,travels from Britam's textile mills to monster steel and carmaking factories in 20th-century America,Europe and the Soviet Union.Mr Freeman rolls up his sleeves and delves into the nitty-gritty of manufaccuring.He successfully melds together those nuggets with social history,on the shop floor and beyond the factory walls,from union bacdes to worker exploitation.Consider,for example,his account of one of the most famous factory bosses of all.Henry Ford launched his Model T in 1908,curning the car from a luxury into a mass-manufactured product.Ford's original facLory used standardised parts and ficted them to vehicles as they travelled along a moving assembly line.The Model T,however,soon became obsolete.As Mr Freeman describes,yhis exposed the weakness of the giant system:it is extremely expensive and slow to switch a giant.factory from one product to another.In 1927 Ford halted produccion and laid o~f 60,000 workers,causing a social crisis in the Delroit area.After six months 15,000 machine tools had been replaced and 25,000 others rebuilt,so that the Rouge was ready to make the new Model
A.At its zenith the factory employed 100,000 people.But it was a brutal place to work,with employees subject to harsh discipline and tyrannical foremen.As the switch from Model T to Model A plunged Ford into loss,Alfred P.Sloan,president of General Motors,presciendy observed that carmakers would need to"adopt the'laws'of Paris dressmakers".That meant bringing out new models more often.The shortening of product cycles and the fickle nature of modern markets has duly seen manufacturing atomise into smaller,nimbler,more specialist facLories.The Rouge,for instance,lives on,but with just 6,000 workers making pick-up trucks.Some see offshoring to low-wage countries,particularly in Asia,as the mega-factory's last hurrah.Yet long supply chains and distant plants are leaving producers vulnerable to rapid changes in their home markets,so production has been trickling back.Meamvhile new materials and manufacturing methods,such as 3D printing,are demolishing the economies-of scale that giant factories have relied on.Although Mr Freeman is not ready to write off his behemoths,he has probably written their obituary.
What is the author's attitude towards the future of the giant factories?
A.Negative.
B.Optimistic.
C.Sympathetic.
D.Tolerant.

Batteries Built by Viruses
What do chicken pox,the common cold,the flu,and AIDS have in common?They're all diseases caused by viruses,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds.
Not everyone runs from the tiny disease carriers,though. In Cambridge,Massachu- setts,scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work,teaching them to build some of the world's smallest rechargeable batteries.
Viruses and batteries may seem like an unusual pair,but they're not so strange for engi-neer Angela Beicher,who first came up with the idea. At the Massachusetts Institute of
Technology(MIT)in Cambridge,she and her collaborators bring together different areas of science in new ways.In the case of the virus-built batteries,the scientists combine what they know about biology,technology and production techniques.
Beicher's team includes Paula Hammond,who helps put together the tiny batteries,and
Yet-Ming Chiang,an expert on how to store energy in the form of a battery.“We're working on things we traditionally don't associate with nature，”says Hammond.
Many batteries are already pretty small. You can hold A,C and D batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year,new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink,ordinary batteries won't be small enough to fit in-side.
The ideal battery will store a lot of energy in a small package. Right now,Belcher's model battery,a metallic disk completely built by viruses,looks like a regular watch battery. But inside,its components are very small一so tiny you can only see them with a powerful microscope.
How small are these battery parts?To get some idea of the size,pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is一 pretty thin,right?Although the width of each person's hair is a bit different,you could probably fit about 10 of these virus-built battery parts,side to side,across one hair. These micro-batteries may change the way we look at viruses.
How tiny is one battery part?
A.Its width is one tenth of a hair.
B.It equals the width of a hair.
C.It is as thin as a piece of paper.
D.Its width is too tiny to measure.
