Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
Garbage cans are not magical portals. Trash does not disappear when you toss it in a can. Yet, the average American throws away an estimated 1,600 pounds of waste each year. If there are no magic garbage fairies, where does all that trash go? There are four methods to managing waste:
Recycling, landfilling, composting, and incinerating. Each method has its strengths and weaknesses. Let’s take a quick look at each.
Recycling is the process of turning waste into new materials. For example, used paper can be turned into paperboard, which can be used to make book covers. Recycling can reduce pollution, save materials, and lower energy use. Yet, some argue that recycling wastes energy. They believe that collecting, processing, and converti g waste uses more energy than it saves. Still, most people agree that recycling is better for the planet
than landfilling.
Landfilling is the oldest method of managing waste. In its simplest form, landfilling is when people bury garbage in a hole. Over time the practice of landfilling has advanced. Garbage is compacted before it is thrown into the hole. In this way more garbage can fit in each landfill. Large liners are placed in the bottom of landfills so that toxic garbage juice doesn't get into the ground water. Sadly, these liners don't always work. Landfills may pollute the local water supply. Not to mention that all of that garbage stinks. Nobody wants to live next to a landfill. This makes it hard to find new locations for landfills.
Compositing is when people pile up organic matter, such as food waste, and allow it to decompose. The product of this decomposition is compost. Compost can be added to the soil to make the soil richer and better for growing crops. While composting is easy to do onsite somewhere, like home or school, it's hard to do after the garbage gets all mixed up. This is because plastic and other inorganic materials must be removed from the compost pile or they will pollute the soil. There's a lot of plastic in garbage, which makes it hard to compost on a large scale.
One thing that is easier to do is burning garbage. There are two main ways to incinerate waste. The first is to create or harvest a fuel from the waste, such as methane gas, and burn the fuel. The second is to burn the waste directly. The heat from the incineration process can boil water, which can power steam generators. Unfortunately, burning garbage pollutes the air. Also, some critics worry that incinerators destroy valuable resources that could be recycled.
Usually, the community in which you live manages waste. Once you put your garbage in that can, what happens to fit is beyond your control. But you can make choices while it is still in your possession. You can choose to recycle, you can choose to compost, or you can choose to let someone else deal with it. The choice is yours.According to the passage which of the following best defines "fincineTaittion"?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Film is an illusion because the moving pictures seen on the screen are not moving at all. A film is actually a series of tiny still pictures, or flames. They appear to be moving because the retina of the human eye retains the impression of an object for a split second after that object has actually disappeared. This principle is known as the persistence of vision. When we look at a single frame of film, the image persists in the brain's visual center for a fraction of a second. Then, the next frame comes along and the brain has to catch up with the new image. Thus, our eyes and brain trick US into thinking that we see a smoothly moving image rather than a series of still ones.
Another illusion of film is known collectively as special effects, the tricks and techniques that filmmakers use when makeup, costume, and stunts are still not enough to make a scene convincing. Special effects artists apply science to filmmaking, showing US things that no plain camera could ever photograph. Even since the introduction of computer graphics in recent decades, the films of today still rely on some special effects that have existed since the early years of cinema.
One category of special effects is called optical or visual effects, tricks made with the camera. One of the pioneers of optical effects was the French filmmaker Georges Méliès, who invented a technique called stop-motion photography. With this technique, a scene is filmed, the camera is stopped, the scene is changed in some way, and then the camera rolls again. Stop motion photography can create the illusion of an actor disappearing on screen. In one short film, an actor's clothes keep returning to his body as he tries to get undressed. Méfiés also invented a technique known as split screen. By putting a card over the camera lens, he prevented half of the frame of film from being exposed. He filmed a scene on the uncovered half of the frame and then backed up the same strip of film in his camera. For the second shot, he covered the exposed half and took another series of pictures on the half that had been covered the first time. With the technique of split screen, it is possible to achieve illusions such as having the same actor play twins.
Mechanical effects are another category of special effects. Mechanical effects are objects or devices used during the filming to create an illusion, such as feathers or plastic chips to simulate snow, and wires to create the illusion that people are flying. Many sound effects are mechanical effects. Wood blocks create a horse's hoof beats, and a vibrating sheet of metal sounds like thunder. During the silent film era, the music machine called the Kinematophone was popular because it could produce the sounds of sirens, sleigh bells, gunfire, baby cries, and kisses-all at the press of a key.
Other mechanical effects are puppets, robots of all sizes, and tiny copies of buildings or cities. To reduce the cost of studio sets or location photography, special-effects technicians create painted or projected backgrounds, which replace the set or add to it. For example, in a long shot of a town, the set might be only a few feet high, and the remainder of the town is painted onto a sheet of glass positioned in front of the camera during filming. In a 1916 silent film called The Flying Torpedo, mechanical effects created the appearance of an enemy invasion of the California seacoast. Technicians threw small contact- rigged explosives into toy cities, scattering the tiny buildings into the air. An artist painted a row of battleships on a board that was only six feet long. Carpenters drilled small holes in the ships, which were filled with small charges of flash powder to simulate guns. An electrician wired the charges so they could be fired on cue from a small battery. For audiences of t -
Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
In today's competitive world, what responsible parent would not want to give their children the best possible start in life? For this reason, many parents want their children, often as young as ten months old, to become familiar with computers. They seem to think that if their children grow up with computers, they will be better equipped to face the challenges of the future.
No one has proved that computers make children more creative or more intelligent. The truth may even be the opposite. Educational psychologists claim that too much exposure to computers, especially for the very young, may negatively affect normal brain development. Children gain valuable experience of the world from their interaction with physical objects. Ten–month–old babies may benefit more from bumping their heads or putting various objects in their mouths than they will from staring at eye–catching cartoons. A four–year–old child can improve hand–eye coordination and understand cause and effect better by experimenting with a crayon than by moving a cursor around a computer screen. So, as educational psychologists suggest, instead of government funding going to more and more computer classes, it might be better to devote resources to music and art programs.
It is ludicrous to think that children will fall behind if they are not exposed to computers from an early age. Time is too precious to spend with a "mouse". Now is the time when they should be out there learning to ride a bike. There will be time later on for them to start banging away at keyboards.The pronoun “they” in paragraph 2 refer to .

Martin Luther King, Jf, is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhooD. M.L., as he was called, was bom in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was bom. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.
M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.When was M.L. bom?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Sharks have gained an unfair reputation for being fierce predators of large sea animals. Humanity's unfounded fear and hatred of these ancient creatures is leading to a worldwide slaughter that may result in the extinction of many coastal shark species. The shark is the victim of a warped attitude of wildlife protection; we strive only to protect the beautiful, non-threatening parts of our environment. And, in our efforts to restore only non-threatening parts of our earth, we ignore other important parts.
A perfect illustration of this attitude is the contrasting attitude toward another large sea animal, the dolphin. During the 1980s, environmentalists in the United States protested the use of driftnets for tuna fishing in the Pacific Ocean since these nets also caught dolphins. The environmentalists generated enough political and economic pressure to prevent tuna companies from buying tuna that had been caught in driftnets. In contrast to this effort on behalf of the dolphins, these same environmentalists have done very little to help save the Pacific Ocean sharks whose population has decreased nearly to the point of extinction.
Sharks are among the oldest creatures on earth, having survived in the seas for more than 350 million years. They are extremely efficient animals, feeding on wounded or dying animals, thus performing an important role in nature of weeding out the weaker animals in a species. Just the fact that species such as the Great White Shark have managed to live in the oceans for so many millions of years is enough proof of their efficiency and adaptability to changing environments. It is time for US humans, who may not survive another 1,000 years at the rate we are damaging the planet, to cast away our fears and begin considering the protection of sharks as an important part of a program for protection of all our natural environment.The phrase “to cast away” means most nearly .

The tourist looking at the African savannah on a summer afternoon might be excused for thinking that the wide yellow grass plain was completely deserted of life, almost a desert. With only a few small thorn trees sticking out through the veldt, there seems to be almost no place for a living creature to hide.
However, under those trees you might find small steenbok, sleeping in the shade, and waiting for the night to fall. There may even be a small group of lions somewhere, their bodies exactly the same shade as the tall grass around them. In the holes in the ground a host of tiny creatures, from rabbits and badgers to rats and' snakes are waiting for the heat to finish.
The tall grass also hides the fact that there may be a small stream running across the middle of the plain. One clue that there may be water here is the sight of a majestic Marshall eagle circling slowly over the grassland. When he drops, he may come up with a small fish, or maybe a grass snake that has been waiting at the edge of a pool in the hope of catching a frog.
The best time to see the animals then, is in the evening, just as the sun is setting. The best time of the year to come is in late September, or early August, just before the rains. Then the animals
must come to the waterholes, as there is no other place for them to drink. And they like to come while it is still light; so they can see if any dangers are creeping up on them.
So it is at sunset, and after the night falls, that the creatures of the African veld rise and go about their business.By "go about their business" the writer means:

According to some accounts, the first optical telescope was accidentally invented in the 1600s by children who put two glass lenses together while playing with them in a Dutch optical shop. The owner of the shop, Hans Lippershey, looked through the lenses and was amazed by the way they made the nearby church look so much larger. Soon after that, he invented a device that he called a “looker”, a long thin tube where light passed in a straight line from the front lens to the viewing lens at the other end of the tube. In 1608 he tried to sell his invention unsuccessfully. In the same year, someone described the “looker” to the Italian scientists Galileo, who made his own version of the device. In 1610 Galileo used his version to make observations of the Moon, the planet Jupiter, and the Milky Way. In April of 1611, Galileo showed his device to guests at a banquet in his honor. One of guests suggested a name for the device: telescope
When Isaac Newton began using Galileo’s telescope more than a century later, he noticed a problem. The type of telescope that Galileo designed is called a refractor because the front lens bends, or refracts, the light. However, the curved front lens also caused the light to the separated into colors. This meant that when Newton looked through the refracting telescope, the images of bright objects appeared with a ring of colors around them. This sometimes interfered with viewing. He solved this problem by designing a new type of telescope that used a curved mirror. This mirror concentrated the light and reflected a beam of light to the eyepiece at the other end of the telescope. Because Newton used a mirror, his telescope was called a reflector
Very much larger optical telescopes can now be found in many parts of the world, built on hills and mountains far from city lights. The world’s largest refracting telescope is located at the Yerkes Observatory in Williams Bay, Wisconsin. Another telescope stands on Mount Palomar in California. This huge reflecting telescope was for many years the largest reflecting telescope in the world until an even larger reflecting telescope was built in the Caucasus Mountains. A fourth famous reflector telescope, the Keck Telescope situated on a mountain in Hawaii, does not use a single large mirror to collect the light. Instead, the Keck uses the combined light that falls on thirty- six mirrors
Radio telescopes, like optical telescopes allow astronomers to collect data from outer space, but they are different in important ways. First of all, they look very different because instead of light waves, they collect radio waves. Thus, in the place of lenses or mirror, radio telescopes employ bowl-shaped disks that resemble huge TV satellite dished. Also, apart from their distinctive appearance, radio telescope and optical telescopes use different methods to record the information they collect. Optical telescopes use cameras to take photographs of visible objects, while radio telescopes use radio receivers to record radio waves from distant object in space.What did Newton do with Galileo’s telescope?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
Urbanization degrades the environment, according to conventional wisdom. This view has led many developing countries to limit rural - urban migration and curb urban expansion. But this view is incorrect. There are a number of reasons urbanization can be good for the environment, if managed properly.
First, urbanization brings higher productivity because of its positive externalities and economies of scale. Asian urban productivity is more than 5.5 times that of rural areas. The same output can be produced using fewer resources with urban agglomeration than without. In this sense, urbanization reduces the ecological footprint. The service sector requires urbanization because it needs a concentration of clients. As services generally pollute less than manufacturing, this aspect of urbanization is also beneficial to the environment.
Second, for any given population, the high urban density is benign for the environment. The urban economics literature shows that compactness is a key determinant of energy use. High density can make public transport more viable and reduce the length of trips. Urban living encourages walking and cycling rather than driving. Third, environment-friendly infrastructure and public services such as piped water, sanitation, and waste management are much easier and more economical to construct, maintain, and operate in an urban setting. Urbanization allows more people to have access to environment-friendly facilities and services at affordable prices.
Fourth, urbanization drives innovation, including green technologies. In the long term, environment-friendly equipment, machines, vehicles, and utilities will determine the future of the green economy. Green innovations in Asia's cities will be supported by the region's vast market as the billions of people who will be buying energy-efficient products will create opportunities and incentives for entrepreneurs to invest in developing such products. Finally, the higher standard of living associated with urbanization provides people with better food, education, housing, and health care. Urban growth generates revenues that fund infrastructure projects, reducing congestion and improving public health. Urbanization fosters a pro-environment stance among property owners and the middle class, which is crucial for the introduction and enforcement of environmental laws and regulations.
Of course, urbanization also comes with costs. Millions of people are migrating to Asian cities and companies are locating there to employ them. Urban sprawl and industrial activities, such as power generation, transportation, construction, garbage and waste disposal, harm the environment. An assessment of the impact of urbanization on the environment must balance its benign and adverse effects.The word “footprint” in paragraph 2 is closest in meaning to ______.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
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.According to the passage, the following are measures to overcome the generation gap, EXCEPT .

As Chinese society changes, higher education is undergoing major transformations. The university model of the United States and other Western countries has a powerful influence. New trends in Chinese higher education are attracting the attention of global educators. Since the establishment of Western-oriented modern universities at the end of nineteenth century, Chinese higher education has continued to evolve. Over the past two decades, however, tremendous economic development in China has stimulated reforms in higher education that have resulted in some remarkable changes.
The first modern institution, Peiyang University, was founded in Tianjin. The university changed its name to Tianjin University in 1951 and became one of the leading universities in China: Next, Jiaotong University was founded in Shanghai in 1896. In the 1950s, most of this university was moved to Xi'an, an ancient capital city in northwest China, and became Xi'an Jiaotong University; the part of the university remaining in Shanghai was renamed Shanghai Jiaotong University.
Tianjin University celebrated its hundredth anniversary in 1995, followed by Xi'an Jiaotong and Shanghai Jiaotong Universities in 1996. Other leading universities, such as Zhejiang University (1897), Beijing University (1898), and Nanjing University (1902) also recently celebrated their hundredth anniversaries, one after another. These celebrations marked the beginning of a new chapter in Chinese higher education.

Dolphins are one of the most intelligent species on the planet, which makes them a very interesting animal to scientists. In their natural habitats, dolphins use various vocalization techniques. They whistle and squeak to recognize members of their pod, identify and protect their young, and call out warnings of danger. They also make clicking sounds used for echolocation to find food and obstacles in dark and murky waters.
Amazingly, the whistling sound that the bottlenose dolphin makes has been found to have a similar pattern to human language. They always make conversational sounds when they greet each other. If you listen to dolphins' squeaks and squeals, it will sound like they are having a conversation.
Dolphins usually use both sound and body language to communicate with each other. It is through gesture and body language, however, that most of their communication with humans comes. Dolphins can be trained to perform complicated tricks. This suggests they have a high level of intelligence and communication capacity. If they work for a long time with a trainer, they are able to recognize and understand human commands.
A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication. After all, dolphins are one of the most intelligent animals. Their ability to communicate is impressive and worthy of study.The word “flick through” in paragraph 4 is closest in meaning to .

Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.
Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.
Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut down.What was initially planned for the nation’s fuel supply in the 1950s and in the early 1960s?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Advertising helps people recognize a particular brand, persuades them tro try it, and tries to keep them loyal to it. Brand loyalty is perhaps the most important goal of consumer advertising. Whether they produce cars, canned foods or cosmetics, manufacturers want their customers to make repeated purchases. The quality of the product will encourage this, of course, but so, too, will affect advertising.
Advertising relies on the techniques of market research to identify potential users of a product. Are they homemakers or professional people? Are they young or old? Are they city dwellers or country dwellers? Such questions have a bearing on where and when ads should be played. By studying readership breakdowns for newspapers and magazines as well as television ratings and other statistics, an advertising agency can decide on the best way of reaching potential buyers. Detailed research and marketing expertise are essential today when advertising budgets can run into thousands of millions of dollars.
Advertising is a fast-paced, high-pressure industry. There is a constant need for creative ideas that will establish a personality for a product in the public’s mind. Current developments in advertising increase the need for talented workers.
In the past, the majority of advertising was aimed at the traditional white family – breadwinner father, non- working mother, and two children. Research now reveals that only about 6 percent of American households fit this stereotype. Instead, society is fragmented into many groups, with working mothers, single people and older people on the rise. To be most successful, advertising must identify a particular segment and aim its message toward that group.
Advertising is also making use of new technologies. Computer graphics are used to grab the attention of consumers and to help them see products in a new light. The use of computer graphics in a commercial for canned goods, for instance, gave a new image to the tin can.The phrase “in a new light” in bold type in paragraph 5 is closest in meaning to .
