The ruined temples of Angkor are perhaps one of the most impressive Seven Wonders of the World. Located in modern day Cambodia near Lake Tonle Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire for the ninth to the fifteenth century. The ruins of Angkor are documented as some of the most impressive ones in the world, rivaling the pyramids of Giza in Egypt. Why this mighty civilization died out is a question that archaeologists are now only beginning to ponder. The answer, it turns out, may be linked with the availability of fresh water.
One possible explanation for the downfall of the Khmer Empire has to do with the inhabitant’s irrigation system. The temples and palaces of Angkor were constructed around a series of artificial reservoirs and canals which were annually flooded to capacity by the Mekong River. Once filled, they were used to irrigate the surrounding paddies and farmland during the course of the year. Farmers were completely dependent on the water for their crucial rice crop. Without consistent irrigation, the farmers would have been unable to maintain functional crop production.
Scientists speculate that toward the end of the Khmer Empire the hydraulic system of the reservoirs and canals broke down. The construction of hundreds of sandstone temples and palaces required an enormous amount of physical labor. In addition, as the capital of Khmer Empire, Angkor contained upwards of one hundred thousand people who resided in and around Angkor. In order to feed so many people, the local farmers were driven to grow food more quickly and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and loss of water led to decrease in the food supply. With the less food available, the people of Angkor slowly began to migrate to other parts of Cambodia, thus leaving the marvelous city of Angkor to be swallowed by the jungle. Therefore, it is speculated that the Khmer Empire may have fallen victim to its own decrepit infrastructure.

When I tell people about the idea of moving out, many people’s reaction is like, “what do your parents say?” because they assume the parents would not like their children to leave them. Well I don’t know if my parents like it but I can tell you my parents support and respect my decision. They think it is good for me to try and live on my own and then I would know it is the best to stay with my family. The most important reason for independent living is to save the travelling time to work. It used to take me one hour fifteen minutes to travel to work from my previous living place. From my new apartment, it just takes me thirty minutes so I saved forty-five minutes’ traveling time. I don’t have to get up so early and I save two-third of my traveling cost. It does not only save my time to travel for work but also from most of the places in Hong Kong. In addition, I gain my personal space and freedom by independent living. I make my own decision all the time, I do not have to say whether I would go home for dinner, I can invite my friends to come up and stay late. Of course, there are some trade-offs in living on your own. If you want to rent an apartment, there are lots of preparatory work to do. You have to keep visiting the apartments to search for your ideal one. You have to negotiate with the landlord about the price, furniture inclusion, who is responsible for the maintenance of the furniture and equipment. My experience was that after we moved into the apartment, it was not until the kitchen cupboard was soaked with water that we found out there was water leakage in the kitchen sink. Money is the main issue in living on your own. You have to be responsible for all the expenses, for example, the rent, electricity, gas, water, telephone, internet bills, etc.  Therefore, you’ve got to be well prepared and save up for your bills. Although I find my transportation time much shorter, the saved time is spent on other things, such as cooking and some other household chores. I think preparing and cooking the food do occupy a significant portion of my time, therefore I always try to make simple meals. On the other hand, I have to regularly tidy up my apartment and wash my clothes, so it doesn’t really save much of my time after all. Now everything is settled down, I’m getting used to my new life and I am enjoying it. I feel that moving out makes it easier for me to strike a balance between my work, my social life, my study and my family. It may be troublesome but it may worth

Globalization can be seen as increased economic, cultural and technological exchange between countries. Examples might be McDonald's in Calcutta and Japanese motor technology in Britain. Many international organizations are pro-globalization, while many others are anti- ones. The main organizations against globalization are the environmental organizations, such as Friends of the Earth and reenpeace, who put forward the belief that globalization harms the environment. In general, these organizations blame global corporations for global warning and the depletion of natural resources. The most obvious is oil and gas, but there are others such as tropical rainforests, which are cut down for timber, and the resources of the sea, which may be affected by pollution. Organizations which represent developing countries, including international aid agencies such as Oxfam, are also against globalization. They are concerned that the global organizations, such as the International Monetary Fund (IMF) and the World Bank, are not doing enough to help the poor and indeed, may be adding to their problems. Some are critical of the World Trade Organization (WTO). They argue that the WTO is making difficult for poor countries to protect and build their own industries. On the contrary, many organizations are in favor of globalization. Perhaps the most important one is the WTO. This organization was set up in 1995 and has 123 member countries. It administers the rules of international trade agreed by its member countries. The WTO's rules make it difficult for a country to favor their own industry over imports from other countries. The WTO argues that the growth of trade between countries increases the wealth of everyone. Trade allows those who can produce goods most cheaply to do so, thus giving everyone the best possible price. Another pro-globalization organization is IMF. This was established after World War II in 1946. It aims to promote international cooperation on finance and provide temporary help for countries suffering financial problems. The IMF has 182 member countries. Finally, the United Nations, which was established after the Second World War, has become a promoter of globalization. It aims to  promote a shared set of values in the areas of labour standards, human rights and environmental practices between the UN and the business community.

The cities in the United States have been the most visible sponsors and beneficiaries  of projects that place art in public places. They have shown exceptional imagination in applying the diverse forms of contemporary art to a wide variety of purposes. The activities observed in a number of “pioneer” cities sponsoring art in public places - a broadening exploration of public sites, an increasing awareness among both sponsors and the public of the varieties of contemporary artistic practice, and a growing public enthusiasm - are increasingly characteristic of cities across the country. With many cities now undergoing renewed development, opportunities are continuously emerging for the inclusion or art in new or renewed public environments, including buildings, plazas, parks, and transportation facilities. The result of these activities is a group of artworks that reflect the diversity of contemporary art and the varying character and goals of the sponsoring communities.  In sculpture, the projects range from a cartoonlike Mermaid in Miami Beach by Roy Lichtenstein to a small forest planted in New York City by Alan Sonfist. The use of murals followed quickly upon the use of sculpture and has brought to public sites the work of artists as different as the realist Thomas Hart Benton and the Pop artist Robert Rauschenberg. The specialized requirements of particular urban situations have further expanded the use of art in public places: in Memphis, sculptor Richard Hunt has created a monument to Martin Luther King, Jr., who was slain there; in New York, Dan Flavin and Bill Brand have contributed neon and animation works to the enhancement of mass transit facilities. And in numerous cities, art is being raised as a symbol of the commitment to revitalize urban areas.  By continuing to sponsor projects involving a growing body of art in public places, cities will certainly enlarge the situations in which the public encounters and grows familiar with the various forms of contemporary art. Indeed, cities are providing artists with an opportunity to communicate with a new and broader audience. Artists are recognizing the distinction between public and private spaces, and taking that into account when executing their public commissions. They are working in new, often more durable media, and on an unaccustomed scale.
1. What is the passage mainly about?

Read the following passage and choose the best answer (A, B, C, D):
A generation gap in the workplace can make workers both young and old feel inferior, as well as hamper productivity and teamwork. Differences between generations can be seen in work ethics, habits and communication styles. Younger workers might fear not being taken seriously by their older colleagues, while older workers might fear that their experience is not valued but replaced by workers with knowledge of more current technology. However, members of each generation can close the gap between them if they’re willing to meet one another halfway. Older workers can show respect to the younger set by asking for their opinions and recognizing their contributions to the workplace as valid, or complimenting them on a job well done. Younger workers can show their elders respect by asking for advice on how to manage a situation with work, based on the older worker’s many years of experience. It’s important for both entry- and senior-level workers to see each other as equals, regardless of the type of position in which they work. No one wants to feel inferior or irrelevant just because of their age. Rather, a generation gap at work can be a learning opportunity. Workers can also put themselves in their colleagues’ shoes to determine what might be bothering them about their generational age difference. If a person is much older than another, perhaps it is bitterness about fewer job opportunities, or fear that a younger worker might seem more relevant and edge him out of his job. If workers open their minds to understand where co-workers are coming from, it can help ease any tension between them and appreciate each other’s work contributions.  If age seems to be a problem for someone at the workplace, it can be helpful to do the very opposite of what a co-worker might expect from someone of a different age set due to stereotypes. For example, if a worker is considerably younger such as right out of college, she can share researched information to indicate that she knows what she’s doing, or show curiosity instead of upset to indicate emotional maturity if the person makes a disparaging remark about her youth. Older workers can maintain an enthusiastic attitude about work instead of showing boredom or bitterness from past experiences. Workers can, moreover, directly address the concern of age differences at work with the colleague at odds with them by asking the person for constructive advice on how to handle the issue. For example, older workers who are unfamiliar with new software that younger colleagues understand might acknowledge to them that they did the same tasks differently in years past but show interest in learning the program to keep up with modern technology. Learning to speak their technological language can make them feel more connected. Likewise, a younger worker can admit to being green on the work scene, but eager to gain experience by learning from senior colleagues.

Read the following passage and choose the best answer (A, B, C, D):
Practical experience is a must-have for today’s job seekers. According to Brazen Life’s Huffington Post article titled “Why Gaining Work Experience Is More Important Than Your Education,” many colleges and universities report that students who have completed an internship or gained work experience during their studies have higher rates of getting hired. For example, at Iowa State University, of all students who completed a co-op program to earn a BS in engineering, an astounding 90 percent got jobs after graduation. Why is practical experience so important? There are a number of reasons why you need practical work experience. First, it’s simply the smart thing to do when you’re preparing for a career in a specific field. Let’s say it’s your dream to work as a consultant for an international corporate relocation company because you love international travel and you like organizing things. So you get a part-time job working as an office assistant at a corporate relocation company… and you find out it’s very different from what you expected. In short, you realize this isn’t the job for you-and you can concentrate on finding another job where you can put your passion and skills to work, for example in the tourism industry. Alternatively, you might find out that you enjoy the corporate relocation business. That means you’re gaining invaluable industry experience that will look great on your resumé when you apply for a full-time job.  Second, practical work experience teaches valuable soft skills, such as discipline, perseverance, teamwork, leadership skills, communication skills and problem solving. Employers will look for these in candidates and they’ll want to see proof. If you’ve spent a month as a team leader at Homes for Heroes, the leadership skills, teamwork experience and problem-solving abilities you developed there can add significant value to your candidacy. Third, working helps you build your network and can provide you with contacts in your chosen field. These contacts can be extremely useful when it comes to hearing about job leads and interesting opportunities. In addition, if you’ve impressed someone, he or she might be willing to write you a letter of recommendation for a job or a place in a graduate program.  Finally, the company you’re working for might offer you a position after you’ve graduated. Your employer already knows your skills and abilities, and you’re already acquainted with the company-so it’s a win-win situation!

Herb Hamrol, 103, is among a handful of survivors of the 1906 San Francisco earthquake. Today marks the 100th anniversary of San Francisco’s great earthquake and fire. As the local newspaper Contra Costa Times observes, San Francisco has been “struggling with the difference between commemoration and celebration” leading up to the centennial. The city’s mayor, Gavin Newsom, has acknowledged that the 1906 earthquake was an “awkward” event to mark. Perhaps curiously, along with various exhibitions and lectures, more than one attempt has been made to capture the spirit of the anniversary in dance. The Walnut Creek Diablo Ballet company has produced “Earthquake”, which its creators stress is not just about death and falling buildings, but also the rebuilding of the city. Earlier this month, the San Francisco Ballet held a one-off solo dance performance to the beat of seismic data broadcast live from the Hayward fault. The information triggered sounds such as thunder claps and crashing waves while principal dancer Muriel Maffre improvised. It was “well conceived and beautiful”, the San Francisco Chronicle reported, although not quite as “leading edge” as claimed. At one stage there was a “haunted-house cacophony of screams and clinking chains and running water”, the paper’s critic said. There is a small, dwindling group of survivors from the quake, many of whom were just babies when it struck. A group of five of them - the oldest is 108 - recently met in San Francisco and happily gave interviews to journalists. They will attend a special commemoration breakfast today. One survivor, Della Bacchini, 101, who was one year old in 1906, told the San Francisco Examiner that it was important for the city’s residents to keep the history of the quake alive. "San Franciscans have a lot of guts," she said. “We’ve gone through earthquakes and fires, and the people have stuck together. Certainly, the city’s regeneration after 1906 was remarkable, with three-quarters of the lost buildings replaced within three years. A reinvented San Francisco was unveiled in 1915 with its Panama-Pacific International Exposition. In a commemorative lecture, Kenneth Starr, professor of history at the University of California, compared the compulsion to rebuild in 1906 with the plans to rebuild New Orleans after last year’s disaster: “Once they’re dreamed, once they’ve been there … they never disappear.

Sunlight is solar energy. Sunlight is needed for growing plants that you eat to get energy. Sunlight is also used to make clean electricity. Burning fossil fuels to make electricity pollutes our atmosphere and rivers. Fossil fuels are expensive and limited sources of energy. Nuclear fission is used to create enormous amount of heat and electricity. However, nuclear fission forms dangerous radioactive waste.
Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool

and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators.
Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars.
Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam. CSP power plants can store large amount of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also burn natural gas to provide the heat that is used to turn water into steam.
Sunlight provides the energy needed to grow plants and make large amount of environmentally friendly heat and electricity. Solar energy can provide power today and for a long time in the future.

Which of the following statements is NOT true?

Read the passage carefully and choose the correct answer.

Communication in general is process of sending and receiving messages that enables humans to share knowledge, attitudes, and skills. Although we usually identify communication with speech, communication is composed of two dimensions - verbal and nonverbal. Nonverbal communication has been defined as communication without words. It includes apparent behaviors such as facial expressions, eyes, touching, tone of voice, as well as less obvious messages such as dress, posture and spatial distance between two or more people. Activity or inactivity, words or silence all have message value: they influence others and these others, in turn, respond to these communications and thus they are communicating. Commonly, nonverbal communication is learned shortly after birth and practiced and refined throughout a person's lifetime. Children first learn nonverbal expressions by watching and imitating, much as they learn verbal skills. Young children know far more than they can verbalize and are generally more adept at reading nonverbal cues than adults are because of their limited verbal skills and their recent reliance on the nonverbal to communicate. As children develop verbal skills, nonverbal channels of communication do not cease to exist although become entwined in the total communication process.

The word reading has a close meaning to ________.

A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometres in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the tune it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word "radar" in fact gets its name from the term "radio detection and ranging". "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots radar is essential for air traffic control tracking ships at sea, and for tracking weather Systems and storms.

The history of American newspapers begins in the early 18th century with the publication of the first colonial newspapers. American newspapers began as modest affairs-a sideline for printers. They became a political force in the campaign for American independence. After independence, the first article of U.S. Constitution guaranteed freedom of the press. The U.S. Postal Service Act of 1792 provided substantial subsidies: Newspapers were delivered up to 100 miles for a penny and beyond for 1.5 cents, when first class postage ranged from six cents to a quarter. The American press grew rapidly during the First Party System (1790s-1810s) when both parties sponsored papers to reach their loyal partisans. From the 1830s onward, the Penny press began to play a major role in American journalism and its interests seemed to remarkably surprised the management board in the journal industry. Technological advancements such as the telegraph and faster printing presses in the 1840s also helped to expand the press of the nation as it experienced rapid economic and demographic growth. Editors typically became the local party spokesman, and hard-hitting editorials were widely reprinted. By 1900 major newspapers had become profitable powerhouses of advocacy, muckraking and sensationalism, along with serious, and objective news-gathering. During the early 20th century, prior to rise of television, the average American read several newspapers per-day. Starting in the 1920s, changes in technology again morphed the nature of American journalism as radio and later, television, began to play increasingly important competitive roles. In the late 20th century, much of American journalism became housed in big media chains. With the coming of digital journalism in the 21st century, all newspapers faced a business crisis as readers turned to the Internet for sources and advertisers followed them

In addition to improved physical health, sport plays a primarily positive role in youth  development, including improved academic achievement, higher self-esteem, fewer behavioral problems, and better psychosocial development. Many studies focus on the effects of sport on the five “C’s” - competence, confidence, connections, character, and caring. The many facets of playing sport - the discipline of training, learning teamwork, following the leadership of coaches and captains, learning to lose - provide lifelong skills for athletes.  The literature on youth sport stresses the positive effects of participation in learning the important life skills of goal setting and time management combined with enjoyment; the development of a strong sense of morality; and the development of an appreciation of diversity. Studies have shown that children and youth participating in sport, when compared to peers who do not play sport, exhibit higher grades, expectations, and attainment; greater personal confidence and self-esteem; greater connections with school – that is, greater attachment and support from adults; stronger peer relationships, more academically oriented friends, greater family attachment and more frequent interactions with parents; more restraint in avoiding risky behavior; and greater involvement in volunteer work.  Sport provides opportunities for children and youth to engage in valuable and positive relationships with adults. Thus, it is a missed opportunity for children who are "gated" - or not included in sport - during early stages of childhood because they are less well behaved than other children. These children are being prevented from participating in the very thing that could help them learn to control and regulate their behavior. Sport provides an opportunity for children to safely navigate and negotiate between right and wrong as they learn to interact with peers and adults. Research by Taliaferro et al. suggests that playing sport can even protect against suicide risk in youth. Compared to non-athletes, male athletes exhibit lower levels of hopelessness and suicidal ideation. Young males involved in multiple sports seem to garner even more protection in this regard. Similar results were found for girls. Research on the role of exercise in adults confirms that it improves mood and alleviates many forms of depression. Bartko and Eccles les found that youth who are highly involved in sport are more “psychologically resilient,” that is, better able to recover from problems. Eccles et al. found that sport participation protects young athletes against social isolation

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.

Dr. Daniel Quon has been an oral surgeon in Jackson for over 30 years. “Growing up  in the family business, I knew that in order for you to gain something, you have to give back,” Quon said. “And being in the field of dentistry, we have a special gift that we can help people and I thought that was an appropriate way to help out.”  Quon volunteers his dental services at the Jackson Free Health Clinic to patients who can’t afford it. Through the Mississippi Dental Association, Quon also provides free dental care for the Mission Service of Mercy program. Dental Assistant Carley Welch has been a part of this experience. “We actually did that last year together and we plan on doing that again this year together,” he said. “Best boss you can ask for,” Welch continued. “Very patient, always willing to teach you; even things that most people wouldn’t go very far to teach you, he will. Just so you have the experience.” But Quon serves in other ways too. “Wife and I volunteer at the Stewpot. We serve lunch on Saturdays when we can. I was actually on the board of Stewpot for 3 years until this passed year.” And he donates blood platelet at the Mississippi Blood services. “I’m almost up to 18 gallons right now in donations. That’s a lot of blood! still got a little bit left though.” “It takes very little time to volunteer. It’s a great thing where you can help someone who needs an extra hand or helping hand.” “I think he does his part to contribute as much as possible,” Welch added. “Whether it’s helping dental wise or even just in general with the public.”

Paul Watson is an environmental activist. He is a man who believes that he must do something, not just talk about doing something. Paul believes in protecting endangered animals, and he protects them in controversial ways. Some people think that Watson is a hero and admire him very much. Other people think that he is a criminal. On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd. Watson and the people who work on the Sea Shepherd were hunting on the Atlantic Ocean near Portugal. However, they had a strange prey, instead of hunting for animals, their prey was a ship, the Sierra. The Sea Shepherd found the Sierra, ran into it and sank it. As a result, the Sierra never returned to the sea. The Sea Shepherd, on the other hand, returned to its home in Canada. Paul Watson and his worked thought that they had been successful. The Sierra had been a whaling ship, which had operated illegally. The captain and the crew of the Sierra did not obey any of the international laws that restrict whaling. Instead, they killed as many whales as they could, quickly cut off the meat, and froze it. Later, they sold the whale meat in countries where it is eaten. Paul Watson tried to persuade the international whaling commission to stop the Sierra. However, the commission did very little, and Paul became impatient. He decided to stop the Sierra and whaling ships in any way that he could. He offered to pay $25,000 to an one who sank any illegal whaling ship, and he sank the Sierra. He acted because he believed that the whales must be protected. Still, he acted without the approval of the government; therefore, his action controversial. Paul Watson is not the only environmental activist. Other men and women are also fighting to protect the Earth. Like Paul Watson, they do not always have the approval of their governments, and like Watson, they have become impatient. Yet, because of their concern for the environment, they will act to protect it.
