28、ast （ C） ahead （ D） before 60 Some people just wont shut up. Thats probably been true for a long time maybe even hundreds of thousands of years. Computer reconstructions of ancient skulls (头骨 ) show that our ancestors had ears built like ours as far back as 350,000 years ago. The ears of social mamm

29、als(哺乳动物 ) are typically designed to recognize sounds made by fellow species members. “So, humanlike ears suggest humanlike speech“, say researchers from Spain. Anthropologists(人类学家 ) dont know for sure when people started talking. To get a better idea, the new study focused on a group of fossils(化石

30、 ) from a place in Spain called Sima de los Huesos. The fossils belong to a species(人种 ) called Homo heidelbergensis. Modem people did not evolve from H. heidelbergensis, but an ancient group called Neandertals might have. Using a computerized scanner(扫描机 ), the researchers measured ear structures o

31、n the remains. Then, they used information about living people to make three-dimensional (三维的 )computer models of what the ancient ears looked like. Finally, they measured how sound would pass through the model ears. The results showed that the ears could handle almost exactly the stone range of sou

32、nds that our ears can today. The researchers suggest that hearing and talking developed in a common ancestor shared by both Neandertals and modern people. Other experts are more skeptical(怀疑的 ). Some studies have turned up conflicting results about the ears and vocal chords(声带 ) of Neandertals. And

33、anyway, hearing could have evolved long before talking. The two dont necessarily go together. If its true that our ancestors could talk more than 350,000 years ago, that brings up another question. What kinds of things did they talk about? 60 “Social mammals“ in the second paragraph means “_“. （ A）

34、our ancestors （ B） a kind of ancient human tribe （ C） Homo heidelbergensis （ D） Neandertals 61 Researchers began their research work with the ancient ears most probably because _. （ A） hearing mid talking developed in a common ancestor shared by both Neandertals and modern people （ B） hearing might

35、have evolved long before talking （ C） computers can make three-dimensional models of what the ancient ears looked like （ D） humanlike ears suggest humanlike speech 62 Which of the following sentences is tree accord to this article? （ A） Anthropologists and experts all agree with each other to their

36、findings. （ B） Measuring how sound would pass through the model ears is the second step in the research. （ C） The fossils from Sima de los Huesos belong to H. heidelbergensis. （ D） The fossils from Sima de los Huesos belong to Neandertals. 63 Which of the following is the best title of this article

37、according to your understanding? （ A） Anthropologists Researches. （ B） The Vocal Chords of Our Ancestors. （ C） The Ears of Our Ancestors. （ D） Words of the Distant Past. 64 Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other th

38、ings. Someday, if you dont mind carrying a heavy load, your backpack might also power your MP3 player, keep your cell phone running, and maybe even light your way home. Scientists from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass., have inve

39、nted a backpack that makes electricity from energy produced while its wearer walks. The backpacks electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearers back, and the whole pack moves up and down as the person walks. A mechani

40、sm with gears collects energy from this motion and transfers it to an electrical generator. Surprisingly, the researchers found, people walk differently when they wear the springy packs. As a result, wearers use less energy than when lugging regular backpacks. Also, the way the new packs ride on wea

41、rers backs makes them more comfortable than standard packs, the inventors say. The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. These people often rely on global positioning system (GPS) receivers, night-vision

42、 goggles, arid other battery-powered devices to get around and do their work. Because the pack can make its own electricity, users dont need to give up space in their packs to lots of extra batteries. For the rest of us, power-generating backpacks could make it possible to walk, play video games, wa

43、tch TV, and listen to music, all at the same time. Electricity-generating packs arent on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street! 64 The first paragraph hints (暗示 ) _. （ A） backpacks are convenient （ B） someday backpacks can gener

44、ate electricity （ C） MP3 players and cell phones can also be put into a backpack （ D） backpacks hold things for people so as to free their hands to do other things. 65 In near future people relying on battery-powered devices to get around and do their work dont need to give up space in their packs t

45、o lots of extra batteries because _. （ A） their heavy packs can make electricity （ B） battery-powered devices will be improved a lot （ C） they typically carry heavy backpacks （ D） global positioning system (GPS) receivers and night-vision goggles work themselves 66 The electricity-generating packs a

46、re likely to be dangerous to us _. （ A） while lighting his way （ B） when playing video games, watching TV, and listening to music, all at the same time （ C） while crossing the street （ D） at the time when creating powers 67 The backpacks electricity comes from _. （ A） the gears with battery-powered

47、devices （ B） the motion of the whole backpack while one walks （ C） a mechanism with gears （ D） an electrical generator 68 If youre like most kids, you probably think youll never get old. Achy joints, failing eyesight, heart attacks: These are things you wont have to deal with for a long time, right?

48、 So why worry now? As it turns out, the choices you make now can make a big difference in how you feel later in life. I recently learned this lesson the hard way. It started with an injury: a cracked shinbone caused by too much running on hard pavement. My doctor suggested a bone scan, which showed

49、that my bones axe weaker than average. I dont have osteoporosis, a disease that causes older people to shrink in height and break bones easily. But Im close. For me, the diagnosis was a scary wakeup call. Im just 27 years old, but already Im worried about things that normally happen only to women more than twice my age. Will I break my hip if I slip on a patch of ice? Is it sale for me to go skiing, lift heavy boxes, play Ultimate Frisbee? Pe
