　　They may be just passing your office, computer bag slung(悬挂)over one shoulder．Or they may be sitting in a car outside it, causally tapping away at a laptop．They look like innocent passers-by．In fact, they are stealing your corporate secrets．

　　Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them．A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way．Security experts patrolled(巡逻)several streets in the City of London seeking evidence of wireless networks in operation．

　　Of 124 that they identified, 83 were sending data without encrypting(加密)them．Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet．

　　The data could include sensitive company documents containing valuable information．Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users．

　　Most companies using wireless networking technology do not take even the simplest of measures to protect their data．Nearly all wireless network technology comes with some basic security features that need only to be activated(激活)in order to give a minimum level of security, for example, by encrypting the data being passed over the network．

　　Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem．People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls．

　　Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in．Switching on the security that comes with the network technology should be automatic．Then there are other basic steps a company can take, says Mr．Kruck, such as changing the passwords on the network from the default(默认)setting．

　　Companies can also install firewalls, which form a barrier between the internal network and the public Internet．They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker．

　　With the Tesla Roadster and other plug-in(插入式)electric vehicles hitting the road，demand is growing for accessible refueling points to recharge them．Carbon Day Automotive, a Chicago-based company，has now demonstrated a solar-powered recharging point, known as the Solar Plug-In Station，which lets motorists easily charge their cars using electricity that has been produced without any environmental damage．

　　The Solar Plug-In Station has gone on show in Chicago as part of the city's bid to host the 2016 Olympic Games．According to Carbon Day Automotive，the Solar Plug-In Station on show in Chicago is part of the vital infrastructure(基础设施)required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee．

　　These solar-powered electricity points will be used daily to fuel the city's electric vehicles with power from the sun．By producing the electricity from pollution-free solar cell, the CO2 emissions are reduced to zero．

　　“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil, ” says Richard Lowenthal, CEO of Coulomb Technologies．Coulomb Technologies recently developed the components(部件)required for individual recharging stations，marketed as ChargePoint Networked Charging Stations．Carbon Day Automotive is the Midwest distributor for the ChargePoint stations．

　　The Solar Plug-In Station consists of giant solar panels(电池板)that shade the tiny ChargePoint Networked Charging Station．The solar panel is connected to an underground battery pack，ready for everyday refueling．

　　“Without these stations it would be like driving around in a traditional car without the availability of gas stations，” says Scott Emalfarb，CEO at Carbon Day．“The day of true plug-in electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate them．”

阅读下列短文，从每题所给四个选项(A、B、C、D)中选出最佳选项。

　　Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water．Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked．Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price．

　　A new study finds that fear of losing your phone is a common illness．About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”．Interestingly, more women worry about losing their phone than men．

　　Fortunately, there's a solution．

　　The first step is to figure out if you have nomophobia．Checking your phone too often is one thing, but the true sign of a problem is that you can't conduct business or go about your routine when the fear becomes so severe．

　　Do you go to unusual lengths to make sure you have your phone? That's another sign of a problem．If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem．

　　Some of the treatments are similar to those for treating anxiety attacks： Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety．Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone．

　　Of course, there are also technological alternatives．Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone．To find it, he can just go to a Web site and see the phone's location．

　　He also insures his phone through a service called Asurion．The company's description of its product reads like a prescription for anxiety： “60 million phones are lost, stolen or damaged each year．You'll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day! ”

　　Anyone who cares about what schools and colleges teach and how their students learn will be interested in the memoir(回忆录)of Ralph W．Tyler, who is one of the most famous men in American education．

　　Born in Chicago in 1902, brought up and schooled in Nebraska, the 19-year-old college graduate Ralph Tyler became hooked on teaching while teaching as a science teacher in South Dakota and changed his major from medicine to education．

　　Graduate work at the University of Chicago found him connected with honorable educators Charles Judd and W．W．Charters, whose ideas of teaching and testing had an effect on his later work．In 1927, he became a teacher of Ohio State University where he further developed a new method of testing．

　　Tyler became well-known nationality in 1938, when he carried his work with the Eight-Year Study from Ohio State University to the University of Chicago at the invitation of Robert Hutchins．

　　Tyler was the first director of the Center for Advanced Study in the Behavioral Sciences at Stanford, a position he held for fourteen years．There, he firmly believed that researchers should be free to seek an independent(独立的)spirit in their work．

　　Although Tyler officially retired in 1967, he never actually retired．He served on a long list of educational organizations in the United States and abroad．Even in his 80s he traveled across the country to advise teachers and management people on how to set objectives(目标)that develop the best teaching and learning within their schools．

　　Visitors to Waikiki Beach may have to look twice at the four-legged sufer boarding in to shore just to make sure they are not dreaming, but the regulars are not surprised．They know the eight-year-old pup is Bugsy, a local legend whose owner, David Yew, taught the dog to surf．

　　Yew, 39, got the idea while he and Bugsy were not walking on the beach and came upon a statue of a surfer．Yew placed the dog down on the surfboard to take a photo, and the scene looked so natural that Yew was inspired to take the next step．Soon the two were surfing together．Bugsy loves the water so much that Yew has trouble keeping up．

　　Bugsy wasn't always so full of energy and fun．Two days after Yew, a doctor of emergency medicine, adopted the 12-week-old puppy from a shelter, Bugsy had a serious cough．Yew rushed the pup to the ICU of a vet hospital, where he stayed until Yew could no longer afford to keep him there．Bugsy needed further treatment, so Yew built his own ICU in his apartment and gave the sick pup treatment himself and Bugsy recovered．

　　Since then, the doctor and dog have been inseparable．"Saving Bugsy's life creat unconditional trust between us, "Yew says．"He knows I'll take care of him no matter what happens．"

　　That may be what fuels Bugsy's spirits．The pair surf together every week and have shared other experiences, including skydiving(高空跳伞)．At Yew's wedding to Aimee Kim last year, a tuxedoed(穿晚礼服的)Bugsy carried the rings for them．

　　Bugsy and Yew have given up skydiving, at the bride's insistence．But hang up the board? No way．"I want this dog to experience the same joy that i have in my life, "says Yew．

　　A “blogger” is a person who writes on an Internet website called a “blog”．The word “blog” is a short way of saying “web log”, or “personal website”．Anyone can start a blog, and they can write about anything they like．

　　There are millions of blogs on the Internet today．They provide news, information and ideas to the people who read them．They contain links to other websites．And they provide a place for people to write their ideas and react to the ideas of others．

　　A research company called Perseus has studied more than 3, 000 web logs．It says that blogs are most popular with teenage girls．They use them to let their friends know what is happening in their lives．The study also says that more than 100, 000 bloggers stopped taking part in the activity after a year．

　　However, some people develop serious blogs to present political and other ideas．For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs．And American companies are beginning to use blogs to advertise their products．

　　At the same time, some long-standing blogs have ended．Last week, blogging leader Dave Winer closed his free blog service “weblogs．com”．He said the site became too costly to continue．He started the blog four years ago, and thousands of people had written on it．They are now upset because they did not know that the site was closed．

　　One blog that is still going strong is called Rebecca's Pocket．Rebecca Blood created the website in 1999,．She wrote about the history of blogs on the site．That article led to a book called The Weblog Handbook．It has been translated into four languages so far．

　　Miss Blood says Rebecca's Pocket get about thirty thousand visitors a month．She writes about anything and everything——politics, culture and movies．She recently provided medical advice．And she wrote about how to prevent being stolen from online bank accounts．

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses．However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat．Now, houses of an old yet new type have been widely built．In some parts of the world, people share their houses with their livestock(家畜)．During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses．The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well．The body heat given off by the animals rises to the second floor of the houses, where people live．By sharing their houses with their live stock, people gain a source of heat．People who live in or near cities do not usually keep livestock．However, home builders use the fact that heat rises．This natural law can be used in building houses in these areas．Instead of keeping livestock on the first floor, builders fill it with large rocks．As they are open to the sun's rays during cold weather, these rocks take in heat．They also give off the heat, and, of course, the warm air rises into the living areas of the houses．So these houses are energy saving．Housebuilding becomes a great challenge to building designers and energy engineers．They try to meet this challenge by learning from old traditions and by using modern technology．And someday in the future, people will be able to live in more energy saving houses．

　　It is probably the strangest sport anyone has ever invented．And at first sight, it looks like the easiest．Competitors have to do two things．The first is to stand still．The second is to place their hands anywhere on the body of a car, and keep it there．

　　This is where things start getting difficult．Lots of people are doing the same thing．And the winner of the “handathon” contest is the person who can carry on doing it for the longest time．That person gets to own the car．

　　It still seems to be an easy thing to do．At the beginning it is．Anyone can stand still．But when the contest has been going for four or five days, standing still seems like the most difficult job in the world．And keeping the hand in place over this time becomes an act of serious attention．After a few days, the hand seems to belong to someone else-someone who wants to go home and get some sleep．

　　Competitors are allowed to take a five-minute break every hour to eat, drink or do whatever else is necessary．No one is allowed to lean on the car for support．Winners need to be able to show great powers of attention．They also need to be able to develop special skills．

　　Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete to enter．Entrants in the Longview handathon certainly don't seem to do much preparation．Most say they will prepare by “getting lots of sleep”．Others say they will “eat healthy food” or “pray for success”．The whole event gives ordinary people the chance to do something interesting and win something in the end．

　　Handathons are competitions, but there is little rivalry(敌对)between competitors．They help each other out and keep each other's spirits up．People who drop out early return with food, drink and encouragement．
