  A Great Quake Coming?

  Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area--and they can be devastating. In 1906, for example, a major quake destroyed about 28,000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when the next "Big One" will strike. It's bound to happen someday. At least seven active fault( 断层 ) lines run through the San Francisco area. Faults are places where pieces of Earth's crust( 地壳 ) slide past each other. When these pieces slip, the ground shakes.

  To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.

  One new finding about the 1906 quake is that the San Andreas fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture( 断裂 ) at about 2.7 kilometers per second. During bigger quakes, however, recent observations show that ruptures can happen at rates faster than 3.5 kilometers per second.

  At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco, these pressure pulses( 脉冲 ) traveled away from the city during the 1906 event. As bad as the damage was, it could have been far worse.

  Looking ahead, scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.

  New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city's buildings are old and weak. Analyses suggest that another massive earthquake would cause extensive damage.

  People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while. According to the new research, however, it's not a matter of "if" the Big One will hit. It's just a matter of when.

  Cell Phones

  1Believe it or not, cell phones have been around for over a quarter of a century. The first commercial cell phone system was development by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big and heavy but they have developed into small and light palm-sized models. There have been huge developments in their functions, too: we have had call forwarding, text messaging, answering services and hands-free use for years, but now there are countless new facilities, such as instant access to the Internet and receiving and sending photos.

  2Cell phones have become very common in our lives: recent statistics suggest as many as one in three people on the planet now have a cell phone, and most of them say they couldn’t live without one. Cell phones are used in every area of our lives and have become a necessary tool, used for essential arrangements, social contact and business. They have made it easier to call for help on the highway. They have made it possible to keep in touch with people “on the move” – when people are traveling.

  3Cell phones have made communication easier and have reduced the need for family arguments! We can use cell phones to let our family know we’ll be late or if there’s a sudden change of plan or an emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late: they can now contact their children at nay time.

  4This does not mean that cell phones are all good news. They have brought with them a number of new headaches for their owners: it coasts a lot to replace stolen phones, something that is becoming a frequent occurrence, and have you ever seen such huge phone bills? More serious, however, is the potential health problem they bring: there are fears that radiation from the phones may cause brain tumor ( 肿瘤 ). This may be a time bomb waiting to happen to younger people who have grown up with cell phones that they simply can’t live without!

  Arctic( 北极 ) Melt

  Earth's North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean( 北冰洋 ) fell to a record low.

  Normally, ice builds in Arctic waters around the North Pole each winter and shrinks( 萎缩 ) during the summer. But for many years, the amount of ice left by the end of summer has been declining.

  Since 1979, each decade has seen an 11.4 percent drop in end-of-summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness — becoming 1.13 meters thinner.

  Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That's 38 percent less area than the average cover at that time of year. And it's a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has scientists concerned.

  There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer( 海洋学家 ) at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.

  Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5°Celsius warmer than average and 1.5°C warmer than the previous record high.

  With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea( 波弗特海 ), north of Alaska and western Canada, ice that measured 3.3 m thick at the beginning of the summer measured just 50 centimeters by season's end.

  The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist( 地球物理学家 ) at the U.S. Army Cold Regions Research and Engineering Laboratory in Hanover, N.H.

  Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover.

  Sharing Silence

  Deaf teenagers Orlando Chavez and German Resendiz have been friends since kindergarten( 幼儿园 ). Together the two boys , who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear

  Orlando lost his hearing at the age of one. German was born deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kindergarten.

  “We were in a special class with about 25 other deaf kids.” German remembers. “Before then, I didn’t know I was deaf and that l was different.”

  “Being young and deaf in regular classes was very hard,” signs Orlando. “The other kids didn’t understand US and we didn’t understand them. But we’ve all grown up together, and today, I’m popular because I’m deaf. Kids try hard to communicate with me.”

  Some things are very difficult for the two boys. “We can’t talk on the phone, so if we need help, we can’t call an emergency service,” German signs. “And we can’t order food in a drive-thru.”

  Despite their difficulties, the two boys have found work putting food in bags at a local supermarket. They got their jobs through a “workability” program, designed for teenagers from local schools with different types of learning disabilities .

  German has worked in the supermarket since August, and Orlando started in November.

  “The other people who work here have been very nice to us,” Orlando signs. “They even sign sometimes. At first, we were nervous, but we’ve learned a lot and we’re getting better.”

  The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute for the Deaf in New York.

  Walking to Exercise the Brain

  Do you think sitting and studying all the time will improve your grades? Think again. Getting some exercise may help, too.

  New research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercise.

  Previous research had shown that mice learn, remember, and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don't. Their brain cells also make more connections.

  Neuroscientists from the University of Illinois at Urbana-Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked 1 mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.

  Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less-fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.

  In a second study, 15 elderly people who completed a 6-month aerobic-training course were faster at attention tasks compared with 14 seniors who just did stretching and toning exercises for the same amount of time.

  So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for your grandparents.

  The effects of exercising on the brains of younger people haven't been studied yet. Still, it can't hurt to take occasional study breaks and go for a walk or run around with your friends. You might even do better in school.

  Whatever you do, though, don't try to read and walk at the same time. You could end up hurting yourself!

  Houses of the Future

  What will houses be like in thirty years’ time? No one really knows, but architects are tying to predict.(46)

  Future houses will have to be flexible. In thirty years’ time even more of us will be working from home. So we will have to be able to use areas of the houses for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home.(47). Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.

  Everyone agrees that in thirty years’ time we will be living in “intelligent” house. We will be able to talk to our kitchen machines and discuss with them what to do. Like this “we’ll be having a party this weekend. What food shall we cook?”(48). We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.

  The house of the future will be personal – each house will be different (49). You won’t have to paint them – you’ll be able to tell the wall to change the color! And if you don’t like the color the next day, you will be able to have a new one.(50)
