Geothermal energy offers enormous potential for direct, low-temperature applications. Unlike indirect applications, this new technology relies on the Earth's natural thermal energy to heat or cool a house or multifamily dwelling directly without the need to convert steam or other high-temperature fluids into electricity, using expensive equipment. A geothermal system consists of a heat pump and exchanger plus a series of pipes, called a loop, installed below the surface of the ground or submerged in a pond or lake. Fluid circulating in the loop is warmed and carries heat to the home. The heat pump and exchanger use an electrically powered vapor-compression cycle - the same principle employed in a refrigerator - to concentrate the energy and to transfer it. The concentrated geothermal energy is released inside the home at a higher temperature, and fans then distribute the heat to various rooms through a system of air ducts. In summer, the process is reversed: excess heat is drawn from the home, expelled to the loop, and absorbed by the Earth. Geothermal systems are more effective than conventional heat pumps that use the outdoor air as their heat source (on cold days) or heat sink (on warm days) because geothermal systems draw heat from a source whose temperature is more constant than that of air. The temperature of the ground or groundwater a few feet beneath the Earth's surface remains relatively stable – between 45°F and 70°F. In winter, it is much easier to capture heat from the soil at a moderate 50°F than from the atmosphere when the air temperature is below zero. Conversely. in summer, the relatively cool ground absorbs a home's waste heat more readily than the warm outdoor air. The use of geothermal energy through heat-pump technology has almost no adverse environmental consequences and offers several advantages over conventional energy sources. Direct geothermal applications are usually no more disruptive of the surrounding environment than a normal water well. Additionally, while such systems require electricity to concentrate and distribute the energy collected, they actually reduce total energy consumption by one-fourth to two-thirds, depending on the technology used. For each 1,000 hones with geothermal heat pumps, an electric utility can avoid the installation of 2 to 5 megawatts of generating capacity. Unfortunately, only a modest part of the potential of this use for geothermal energy has been developed because the service industry is small and the price of competing energy sources is low.
6. The passage implies that a rise in cost of conventional energy would have what effect?

There is a natural balance to all things: life and death, good and bad, happiness and sadness, pleasure and pain. The very idea that you should focus on positives and ignore negatives, likewise with strengths versus weaknesses, is not only delusional; it's a recipe for disaster. Let me tell you a couple of stories to show how dealing with reality as openly and genuinely as possible is the path to success and happiness, while focusing only on the positives and strengths can destroy your career and your company. It's no secret that Steve Jobs was forced out of Apple in 1984 because his management style had become toxic to the company. Much later, Jobs would come to realize that getting fired from the company he cofounded "was the best thing that could have ever happened” to him. He called it “awful-tasting medicine" that "the patient needed." He also likened it to life hitting him in the head with a brick. That forced Jobs to look in the mirror and see the truth - that he wasn't as capable or as strong a leader as he could be. And as he addressed the issues that stood in his way, the result was the founding of NeXT and Pixar, his eventual return to Apple, and the greatest turnaround in corporate history that built the most valuable company on Earth. It's easy to miss the obvious connection staring us right in the face, that it wasn’t just Apple that had hit a wall, fallen on hard times, and found itself in need of a turnaround. The same was true of Jobs. And there was an undeniable connection between the two. It's also easy to miss the insightfulness of Jobs' realization that none of his later achievements would have occurred if he hadn't faced reality. That sort of introspection only comes from someone who's had some sort of intervention and gone through gut-wrenching change as a result. Not to compare myself with Jobs, but the truth is I've gotten a couple of those bricks to the head myself. I've been fired more than once and lost my wife early in our marriage. But in every case I looked in the mirror, faced what I saw, made some changes, and bounced back stronger than ever. If I'd just tried to stay positive, focused on my strengths, and searched for the silver lining in the clouds, I never would have figured out what was wrong and become a better person, a better husband, and a better leader. I never would have achieved so much in my career or won my wife back. While life is full of ups and downs, one thing is certain: If you attempt to filter your consciousness and disallow negative thoughts or make believe the weaknesses holding you back don't exist, you'll never get past those hurdles and get to the next stage in your personal and professional development. And neither will your business.
9. The phrase "filter your consciousness" in the last paragraph mostly means ____.

I spend my days fighting poverty in New York City, so this time of year I get asked a lot at holiday parties what people can do to help the poor. I like the question. At the Robin Hood Foundation, we've spent 27 years trying to answer it.  As with any complex social issue, there are myriad reasons that people are poor. So we break down the problem to create short and long-term change. We aim to make life better for people who are poor while at the same time attacking the root causes of poverty. Once we've identified the various needs, we use empirical data to identify and support programs that create real results.  It's a process that works for our organization, and it can work for charity-minded individuals too. Getting smart about the underlying causes of poverty will allow you to connect on a deeper level, which matters: Donors are more likely to commit to a cause when it resonates emotionally. From there, you can then do a little digging to determine which organization is worthy of your support.  So, in case we don't see each other at a party this season, there are six key barriers poor people regularly face: homelessness, hunger, health, unemployment, immigration, and education. And while they are often interconnected, eliminating just one leads to an improved living standard. Whichever tugs at your heart, there's a group in your area ready to use your time or money effectively.

Despite predictions that the traditional media were going to disappear in the internet age, newspapers, the radio and television have managed to survive. However, their survival has come at a price. Digital technology has given birth to social media, tools that allow ordinary people to create, share and exchange information without the need for the usual news channels. Moreover, social media is also attracting a large share of advertisers' money away from the traditional media. As a result, newspapers, the radio and television are always looking for ways to hurt their new rival and they are more than happy to publish stories that play on people's fears about how untrustworthy and unsafe social media is. As all football fans know, the sports media has to work harder between matches to fill their pages and sites. The most popular method of doing this is by speculating about the players that clubs might buy or sell, especially talented foreigners. However, many readers often suspect that these stories are the products of lazy journalism and, if not completely false, contain very little truth and a lot of exaggeration. One Irish football fan decided to find out by using social media to invent Masal Bugduv, a sixteen-year old football superstar from the small Eastern European country of Moldova. The fan set up a Wikipedia page for the player that explained that Bugduv had already played for his national team and that his nickname was 'Massi'. He then wrote false press agency stories that claimed Bugduv would soon join Arsenal and sent them to sports blogs. The blogs accepted the stories as true, but the big surprise came when The Times newspaper included an article entitled Football's Top 50 Rising Stars. At number thirty on the list was 'Moldova's finest', sixteen-year-old Masal Bugduv, who had been linked with Arsenal and 'plenty of other top clubs as well.' While most people would agree that the traditional press should warn people about the dangers of new technology, it is also good to know that social media can expose the unprofessional practices of some journalists. The more they zoom in on each other's unacceptable practices, the better for the readers

Maria Alcalá of Madrid speaks for many Mediterranean people when she says that “a meal without olive oil would be a bore.” No one knows when the Mediterranean civilizations initially fell in love with olives. That occurred before recorded history. However, there is evidence that the cultivation of olive trees began in countries around the Mediterranean Sea in approximately 4000 B.C., and 2,000 years after that people in the eastern Mediterranean region began to produce oil from olives. The Mediterranean still accounts for 99 percent of all world olive oil production. From ancient times until today, the basic process of producing the oil is the same. First, whole olives are crushed. Then, the liquid is separated from the solids. After that, the valuable oil is separated from the water. Many olive growers maintain their ancient traditions and still harvest the olives by hand. “We harvest in the traditional way,” says Don Celso, an olive farmer from Tuscany, Italy. "It would be less expensive to do it with machines, but it's more a social thing. Twenty people come to help with the harvest, and we pay them in oil." Olive oil has had a variety of uses through its long history. In ancient times, olive oil was used as money and as medicine. It was even used during war-heated up and dropped down on attackers. It is still used in religious ceremonies. It is great for protecting the freshness of fish and cheese. There are even olive oil lamps and olive oil soaps. Olive oil enhances the lives of people everywhere. Its benefits, recently confirmed by science, were already understood in ancient times. Mediterranean people are happy to share their secret with the world.

Welcome to Trang An, Vietnam's newest UNESCO World Heritage Site, a place where the water is crystal clear and pink flowers bloom along the shallows. Temples rest on a precipice of rock and water. Here, for 30,000 years, people have lived amongst these limestone giants. To the unfamiliar, this area is a maze of confusing waterways and impassable hills, a place where one could easily disappear from the world. However, to the emperors of the 10th and 11th centuries, this was the ideal setting for a capital city where the inhabitants could be controlled and enemies rebuffed.  This combination of stunning natural beauty and ancient history has led Trang An to be recognised as Vietnam's eighth World Heritage Site. Unlike the previous seven, Trang An is notable for being the only UNESCO site in Vietnam to be classified for both its cultural beauty and natural integrity.  At the ticket office, we are met by the sight of thousands of wooden boats bobbing along the shoreline. Stepping gingerly into the closest dinghy, we are greeted by a young woman whose ability to paddle three adults - all in the midst of Christmas feasting - for three straight hours left me in awe of her strength. What followed was a string of beautiful caves of varying heights and lengths, interspersed with scenes of a peaceful beauty that can be hard to come by in Vietnam.  Dubbed ‘Halong Bay on land’, Trang An’s landscape is reminiscent of its coastal World Heritage neighbour. Dominated by similar karst geography, Halong Bay and Trang An both provide a stunning backdrop lo a tranquil boat cruise. Unlike Halong, however, the boats at Trang An are small, seating no more than five adults, and weekday crowds are minimal. We emerged from a particularly low cave opening and into a small cove ringed by flowering reeds and waterlilies. The steep limestone cliffs block all outside sounds. Underwater reeds stand tall in the clear water beneath our boat, their green spongy limbs waving gently in the current as we paddle past. Brown-and-gold fish dart between grass, their scales glinting in the sunlight, before plunging into the shadows of the towering hills above. Water movement is imperceptible, with the steep hillsides, plunging valleys and clear sky mirrored in its glassy surface. It is as though a parallel world of deep crevices and underwater mountains exists just below our feet.  A parallel world does, in fact, describe how it seemed as we floated through the caves of Trang An. The journey through the first hollow felt like stepping through the back of the wardrobe and entering Narnia. We were suddenly transported into a beautiful, magical world. So at odds with the industrial limestone factories that dominate the Ninh Binh landscape, this small pocket of serenity is surprising.  With more and more visitors flocking to Vietnam's World Heritage Sites, I worry that Trang An will suffer the consequences of unchecked mass tourism. We can only hope that tourism officials will learn from the experiences of other popular tourist destinations and ensure that this place remains as close to paradise as it was on our visit.

Increasing numbers of parents in the U.S. are choosing to teach their children at home. In fact, the U.S. Department of Education has estimated that in 1999, about 850,000 children were being homeschooled. Some educational experts say that the real number is double this estimate, and the ranks of home-schooled children seem to be growing at the average rate of about eleven percent every year. At one time, there was a theory accounting for home-schooling: it was traditionally used for students who could not attend school because of behavioral or learning difficulties. Today, however, more parents are taking on the responsibility of educating their own children at home due to their dissatisfaction with the educational system. Many parents are unhappy about class size, as well as problems inside the classroom. Teacher shortages and lack of funding mean that, in many schools, one teacher is responsible for thirty or forty students. The children are, therefore, deprived of the attention they need. Escalating classroom violence has also motivated some parents to remove their children from school. Although there have been a lot of arguments for and against it, home-schooling in the U.S. has become a multi-million dollar industry, and it is growing bigger and bigger. There are now plenty of websites, support groups, and conventions that help parents protect their rights and enable them to learn more about educating their children. Though once it was the only choice for troubled children, homeschooling today is an accepted alternative to an educational system that many believe is failing.
