College is a new and different experience for me. I’m away from home, so I have  many things to adjust to. Being on my own, talking with friendly people, and having Fridays off - these are just some things I like about college.  Living at college, first of all, gives me a sense of responsibility, of being on my own. My parents are not around to say, “No, you’re not going out tonight.” Or “Did you finish your homework?” Everything I do has to be my decision, and that gives me the responsibility of handling my own life. During the second week I was at college, I had to go out and look for a bank where I could open an account. Before that I looked in the phone book since I had no clue about any banks around here or where they were located. Someone told me to go to a bank named Continental Federal Savings. And I had to make my own decision - whether to have a checking or saving account and whether or not to get a card. I’m on my own to make my own decisions.  I also love to have Fridays off. I wouldn’t be able to deal with five days of classes in a row. I love to sleep in. One Thursday night, my roommates and I went to Georgetown. We got in rather early the next morning, and my roommates and I decided to sleep in, something I couldn’t do in high school.  I do like things about college - being on my own and having Fridays off, but this doesn’t mean I don’t think about things at home. Although I like college, I can still get homesick: New York is a pretty good place, too.

Modern civilization is heavily dependent on energy. Without reliable power sources, e coulnt operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy.
Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward.
Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap.
The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. I they happen to have a meltdown, this could destroy the surrounding area for years to come.
The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

My children can’t live without media. At age 14, 15 and 18, my daughters Sussy and Anni and my son Bill don’t use media. They inhabit media. And they do so exactly as fish inhabit a pond. Gracefully, and without consciousness and curiosity as to how they got there. They don’t remember a time before email or instant messaging or Google. When my children laugh, they don’t say “Ha, ha”. They say “LOL”. These are children who shrug indifferently when they lose their iPods, with all 5000 tunes plus video clips, feature films, and TV shows (like who watches TV on a television anymore?). “There is plenty more where that came from”, their attitude says. And they seem right. The digital content that powers their world can never truly be destroyed. As a social scientist, journalist, and mother, I’ve always been an enthusiastic user of information technology. But I’d noticed that the more we seemed to communicate as individuals, the less we seemed to function together as a family. And on a broader scale, that the more facts we have at our fingertips, the less we seem to know. That the “convenience” of messaging media (email, SMS, IM) consumes ever larger amounts of our time. That as a culture we are practically swimming in entertainment, yet remain more depressed than any people who have ever lived. Our family’s self-imposed exile from the information age changed our lives infinitely for the better. I watched as my children became more focused. I watched as their attention spans increased, allowing them to read for hours at a time; to hold longer and more complex conversations with adults and among themselves. They probably did no more homework during The Experiment than they had done before, but they all completed it far more efficiently and far more quickly The Experiment also forced us to notice food more. Before, eating had been a side dish. Now it was the main course, or at least one of them. Our approach to cooking changed, too, especially for the girls. They’d started out as reasonably competent cooks, but by the end of The Experiment they were capable of turning out entire meals with ease The Experiment also confirmed my strong suspicion that media has been robbing Sussy of sleep for years. Unplugged, the changes to her sleep patterns were dramatic. The evidence strongly suggests she is no isolated case. One study found that children who spend more time online also drink more caffeinated beverages, with a resulting effect on their prospects of sleeping well

The Internet is very much like television, in which it takes time away from other pursuits, provides entertainment and information, but in no way can compare with the warm, personal experience of reading a good book. This is not the only reason why the Internet will never replace books, for books provide the in-depth knowledge of a subject that sitting in front of a computer monitor cannot provide. We can download text from an Internet source, but the aesthetic quality of sheets of downloaded text leave much to be desired. A welldesigned book enhances the reading experience. The book is still the most compact and inexpensive means of conveying a dense amount of knowledge in a convenient package. The easy portability of the book is what makes it the most user-friendly format for knowledge ever invented. The idea that one can carry in one’s pocket a play by Shakespeare, a novel by Charles Dickens or Tom Clancy, Plato’s Dialogues, or the Bible in a small paperback edition is mind-boggling. We take such uncommon convenience for granted, not realizing that the book itself has undergone quite an evolution since the production of the Gutenberg Bible in 1455 and Shakespeare’s First Folio in 1623, just three years after the Pilgrims landed at Plymouth to colonize the New World. Not only has the art and craft of printing and book manufacturing been greatly improved over the centuries, but the great variety of subject matter now available in books is astounding, to say the least. In fact, the Internet requires the constant input of authors and their books to provide it with the information that makes it a useful tool for exploration and learning.  Another important reason why the Internet will never replace books is because those who wish to become writers want to see their works permanently published as books - something you can hold, see, feel, skim through, and read at one’s leisure without the need for an electric current apart from a lamp. The writer may use a word processor instead of a typewriter or a pen and pad, but the finished product must eventually end up as a book if it is to have value to the reading public. The writer may use the Internet in the course of researching a subject just as he may use a library for that purpose, but the end product will still be a book.

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
Being aware of one's own emotions - recognizing and acknowledging feelings as they happen - is at the very heart of Emotional Intelligence. And this awareness encompasses not only moods but also thoughts about those moods. People who are able to monitor their feelings as they arise are less likely to be ruled by them and are thus better able to manage their emotions.
Managing emotions does not mean suppressing them; nor does it mean giving free rein to every feeling. Psychologist Daniel Goleman, one of several authors who have popularized the notion of Emotional Intelligence, insisted that the goal is balance and that every feeling has value and significance. As Goleman said, "A life without passion would be a dull wasteland of neutrality, cut off and isolated from the richness of life itself." Thus, we manage our emotions by expressing them in an appropriate manner. Emotions can also be managed by engaging in activities that cheer us up, soothe our hurts, or reassure us when we feel anxious.
Clearly, awareness and management of emotions are not independent. For instance, you might think that individuals who seem to experience their feelings more intensely than others would be less able to manage them. However, a critical component of awareness of emotions is the ability to assign meaning to them - to know why we are experiencing a particular feeling or mood.
Psychologists have found that, among individuals who experience intense emotions, individual differences in the ability to assign meaning to those feelings predict differences in the ability to manage them. In other words, if two individuals are intensely angry, the one who is better able to understand why he or she is angry will also be better able to manage the anger.
Self-motivation refers to strong emotional self-control, which enables a person to get moving and pursue worthy goals, persist at tasks even when frustrated, and resist the temptation to act on impulse. Resisting impulsive behavior is, according to Goleman, "the root of all emotional self- control."
Of all the attributes of Emotional Intelligence, the ability to postpone immediate gratification and to persist in working toward some greater future gain is most closely related to success - whether one is trying to build a business, get a college degree, or even stay on a diet. One researcher examined whether this trait can predict a child's success in school. The study showed that 4-year-old children who can delay instant gratification in order to advance toward some future goal will be “far superior as students” when they graduate from high school than will 4-year-olds who are not able to resist the impulse to satisfy their immediate wishes.

In paragraph 3, the author explains the concept of awareness and management of emotions by     .

Read the following passage and choose the best answer (A, B, C, D):
The era of “smart cities”, controlled by an ecosystem of sensors, cameras and  algorithms, is fast approaching. In China, state media claim 500 are under construction. In Canada, Alphabet has plans for turning parts of Toronto into a timber-framed tech town as a prototype. Incremental steps are also making cities smarter. Last week, Transport for London announced plans to track Tube passengers through WiFi to monitor congestion. In the US, fast-food drive-throughs will trial number plates scanners to make ordering faster. Individually these services can improve daily life. Integrating them will create something more powerful than the sum of its parts.  Though convenience and safety are the end goals, serious questions about how city authorities will both store and share vast bodies of data must be answered. The fact that surveillance is built into key transport infrastructure will also make it increasingly difficult to avoid without disrupting daily life. The smart city risks creating a panopticon in the name of an easier and better life. The risks of anonymity disappearing will be increased by the use of different data sets, making it more likely that identifiable characteristics may appear. Closely linked to this is the question of data storage and sharing. The treasure trove of personal information will be a tempting target for hackers. This information might also be used by law enforcement, feeding into the existing dangers of mass surveillance and profiling, as is already the case in China.  These concerns have long been levelled at social media and internet-enabled home appliances. Smart city surveillance can be even more insidious. Users can avoid Facebook or hardware such as Alexa. Avoiding basic infrastructure will be near impossible without seriously affecting day-to-day life. TfL has put up signs warning customers of the WiFi tracking, yet the only choice is between tracking and having no signal. Reports on the facial recognition at airports in America suggest that avoiding being automatically scanned will be tough as well. As these systems become more closely enmeshed, avoiding snooping will become increasingly tricky.  The inevitable rise of smart cities is not inherently negative. Harnessing the power of technology and data can potentially help urban environments adapt to challenges such as climate change and overcrowding. Politicians, programmers and academics must work to ensure that does not come at the cost of all-seeing, 24-hour surveillance.

Carefully guiding a needle that's longer than his tiny fingers, a young boy in Pakistan stitches together the leather pieces of a soccer ball. He sits crouched in the corner of a hot, airless shed for 12 hours. For his long day's work, he will earn 60 cents.
The boy is one of more than 200 million children who work at hard, sometimes dangerous jobs all over the world. Child labor exists in two-thirds of the world's nations. From Indonesia to Guatemala, poor children as young as six are sent off to work. Often they are mistreated and punished for not working hard enough. Children mix the gunpowder for firecrackers in China and knot the threads for carpets in India, all for pennies a day. Sometimes they are sold as slaves.
In a speech to the Child Labor Coalition when he was U.S. Secretary of Labor, Robert Reich expressed gratitude for the organization's work to end abuse of child labor, "You turned up the heat, and you got results." He also congratulated Craig Kielburger, then 13, of Canada, who traveled the world for a year fighting for kids' rights. Craig believes kids can make a difference. He offers this advice, "Write letters to companies and government officials. Put pressure on leaders to make changes and to stop the misuse of children."
One solution to the child-labor problem in poor countries is education. "The future of these countries," Secretary Reich declared, "depends on a work force that is educated. We are prepared to help build schools."
Education has helped to make the world a brighter place for one youth, Aghan of India. When he was nine, Aghan was kidnapped from his home and sold to a carpet maker. Aghan's boss was very cruel. "I was always crying for my mother," he recalls. Aghan's dream was to learn to write so that he could send letters to his parents. Fortunately, a group that opposes child labor rescued Aghan from the factory. He was sent to a shelter in New Delhi where he worked hard to learn to write.

According to the article, what is the best way to keep many children from falling victim to the abuse of child labor in the future?

The National Automobile Show in New York has been one of the top auto shows in the United States since 1900. On November 3 of that year, about 8,000 people looked over the "horseless carriages." It was the opening day and the first opportunity for the automobile industry to show off its wares to a large crowd; however, the black-tie audience treated the occasion more as a social affair than as a sales extravaganza. It was also on the first day of this show that William McKinley became the first U.S. president to ride in a car.
The automobile was not invented in the United States. That distinction belongs to Germany. Nikolaus Otto built the first practical internal-combustion engine there in 1876. Then, German engineer Karl Benz built what are regarded as the first modern automobiles in the mid-1880s. But the United States pioneered the merchandising of the automobile. The auto show proved to be an effective means of getting the public excited about automotive products.

By happenstance, the number of people at the first New York show equaled the entire car population of the United States at that time. In 1900,10 million bicycles and an unknown number of horse-drawn carriages provided the prime means of personal transportation. Only about 4,000 cars were assembled in the United States in 1900, and only a quarter of those were gasoline powered. The rest ran on steam or electricity.

After viewing the cars made by forty car makers, the show's audience favored electric cars because they were quiet. The risk of a boiler explosion turned people away from steamers, and the gasoline-powered cars produced smelly fumes. The Duryea Motor Wagon Company, which launched the American auto industry in 1895, offered a fragrant additive designed to mask the smells of the naphtha that it burned. Many of the 1900 models were cumbersome—the Gasmobile, the Franklin, and the Orient, for example, steered with a tiller like a boat instead of with a steering wheel. None of them was equipped with an automatic starter.

These early model cars were practically handmade and were not very dependable. They were basically toys of the well-to-do. In fact, Woodrow Wilson, then a professor at Princeton University and later President of the United States, predicted that automobiles would cause conflict between the wealthy and the poor. However, among the exhibitors at the 1900 show was a young engineer named Henry Ford. But before the end of the decade, he would revolutionize the automobile industry with his Model T Ford. The Model T, first produced in 1909, featured a standardized design and a streamlined method of production—the assembly line. Its lower costs made it available to the mass market.

Cars at the 1900 show ranged in price from $1,000 to $1,500, or roughly $14,000 to $21,000 in today's prices. By 1913, the Model T was selling for less than $300, and soon the price would drop even further. "I will build cars for the multitudes," Ford said, and he kept his promise

How busy is too busy? For some it means having to miss the occasional long lunch;  for others, it means missing lunch altogether. For a few, it is not being able to take a “sickie” once a month. Then there is a group of people for whom working every evening and weekend is normal, and frantic is the tempo of their lives. For most senior executives, workloads swing between extremely busy and frenzied. The vice-president of the management consultancy AT Kearney and its head of telecommunications for the Asia-Pacific region, Neil Plumridge, says his work weeks vary from a “manageable” 45 hours to 80 hours, but average 60 hours.  Three warning signs alert Plumridge about his workload: sleep, scheduling and family. He knows he has too much on when he gets less than six hours of sleep for three consecutive nights; when he is constantly having to reschedule appointments; “and the third one is on the family side”, says Plumridge, the father of a three-year-old daughter, and expecting a second child in October. “If I happen to miss a birthday or anniversary, I know things are out of control.” Being “too busy” is highly subjective. But for any individual, the perception of being too busy over a prolonged period can start showing up as stress: disturbed sleep, and declining mental and physical health. National workers’ compensation figures show stress causes the most lost time of any workplace injury. Employees suffering stress are off work an average of 16.6 weeks. The effects of stress are also expensive.  Comcare, the Federal Government insurer, reports that in 2003-04, claims for psychological injury accounted for 7% of claims but almost 27% of claim costs. Experts say the key to dealing with stress is not to focus on relief – a game of golf or a massage – but to reassess workloads. Neil Plumridge says he makes it a priority to work out what has to change; that might mean allocating extra resources to a job, allowing more time or changing expectations. The decision may take several days. He also relies on the advice of colleagues, saying his peers coach each other with business problems. “Just a fresh pair of eyes over an issue can help,” he says. Executive stress is not confined to big organizations. Vanessa Stoykov has been running her own advertising and public relations business for seven years, specializing in work for financial and professional services firms. Evolution Media has grown so fast that it debuted on the BRW Fast 100 list of fastest-growing small enterprises last year – just after Stoykov had her first child. Stoykov thrives on the mental stimulation of running her own business. “Like everyone, I have the occasional day when I think my head’s going to blow off,” she says. Because of the growth phase the business is in, Stoykov has to concentrate on short-term stress relief – weekends in the mountains, the occasional “mental health” day – rather than delegating more work. She says: “We’re hiring more people, but you need to train them, teach them about the culture and the clients, so it’s actually more work rather than less.”

Social networking sites such as Facebook and MySpace do not help you make more  genuine close friends, according to a survey by researchers who studied how the websites are changing the nature of friendship networks. Although social networking on the internet helps people to collect hundreds or even thousands of acquaintances, the researchers believe that face to face contact is nearly always necessary to form truly close friendships.  “Although the numbers of friends people have on these sites can be massive, the actual number of close friends is approximately the same in the face to face real world,” said psychologist Will Reader, from Sheffield Hallam University. Social networking websites such as Facebook, Bebo and MySpace have taken off rapidly in recent years. Facebook was launched initially in 2004 for Harvard University members but has since expanded to more than 34 million users worldwide. MySpace, which was set up in 2003, has more than 200 million users and was bought by Rupert Murdoch’s News Corporation in 2005 for $580m (£285m). Previous research has suggested that a person’s conventional friendship group consists of around 150 people, with five very close friends but larger numbers of people whom we keep in touch with less regularly. This figure is so consistent that scientists have suggested it is determined by the cognitive constraints of keeping up with large numbers of people. But Dr. Reader and his team have found that social networking sites do allow people to stretch this figure. The team asked more than 200 people to fill in questionnaires about their online networking, asking for example how many online friends they had, how many of these were close friends and how many they had met face to face. The team found that although the sites allowed contact with hundreds of acquaintances, as with conventional friendship networks, people tend to have around five close friends. Ninety per cent of contacts whom the subjects regarded as close friends were people they had met face to face. “People see face to face contact as being absolutely imperative in forming close friendships,” added Dr. Reader. He told the British Association Festival of Science in York that social networking sites allow people to broaden their list of nodding acquaintances because staying in touch online is easy. “What social network sites can do is decrease the cost of maintaining and forming these social networks because we can post information to multiple people,” he said.  But to develop a real friendship we need to see that the other person is trustworthy, said Dr. Reader. "What we need is to be absolutely sure that a person is really going to invest in us, is really going to be there for us when we need them … It’s very easy to be deceptive on the internet."

Environmentalists often fear that tourists will trample all over sensitive natural resource areas, but tourism may bring the needed and only economic incentives to help drive conservation, said Bynum Boley. Ecotourism and natural resource conservation already have a mutually beneficial relationship that is ideal for creating a sustainable partnership. “Ecotourism destinations benefit in the form of enhanced tourism competitiveness from the protection of quality natural resources,” he said. "Meanwhile, the conservation of these natural resources is increasingly valued since these pristine natural resources are the foundation of the ecotourism industry and the driver of all economic benefits associated with ecotourism." Tourism is a $7.6 trillion global industry, provides 277 million jobs and is a primary income source for 20 of the world’s 48 least-developed countries. It also subsidizes environmental protection and helps protect, conserve and value cultural resources that might otherwise be undervalued by the host community, Boley said. In the newpaper, Boley and coauthor Gary Green said that despite past tension between the tourism industry and environmentalists, the two should team up as allies to fight off increasing conversion of land away from its natural state. Ecotourists not only provide a boost to the economy in such places, they can also motivate landowners into keeping the environment in its natural state instead of converting it into something unsustainable. They could also influence the public perception of conservation, Boley explained, which does not often favor environmental protection. “The public has become increasing less prone to respond to environmental messages,” he said. “Economic messages are needed in order to attract the public’s interest.” Too often, Boley and Green said, unique natural resource areas are converted into urban, suburban and agricultural developments without considering their ecotourism potential. In addition to the lost ecotourism revenue, there are a host of negative environmental consequences such as biodiversity loss, water and food shortages and the land being unable to mitigate the effects of climate change. These areas are not valued for their unique attributes or the valuable natural resources they provide, Green said, “so we lose them.” Tourists have historically been seen as having a negative impact on the environment. Critics complain that they violate fragile and threatened natural environments while contributing to greenhouse gases from the increased number of flights to these exotic and often remote locales. While these criticisms are justified, Boley and Green said responsible programs promote education of ecological conservation and environmental sustainability, fostering a greater understanding and appreciation of these exotic areas

Certainly no creature in the sea is odder than the common sea cucumber. All living creature, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by gourmets? For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to such up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of colors, ranging from black to reddish-brown to sand-color and nearly white. One form even has vivid purple tentacle. Usually the creatures are cucumber-shaped-hence their name-and because they are typically rock inhabitants, this shape, combine with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents. Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become quiescent and live at a low metabolic rate-feeding sparingly or not at all for long periods, so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in a short time and would probably starve themselves out of existence. But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs, when attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attached or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.
