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:
The hard, rigid plates that form the outermost portion of the Earth are about 100 kilometers thick. These plates include both the Earth's crust and the upper mantle. The rocks of the crust are composed mostly of minerals with light elements, like aluminum and sodium, while the mantle contains some heavier elements, like iron and magnesium. Together, the crust and upper mantle that form the surface plates are called the lithosphere. This rigid layer floats on the denser material of the lower mantle the way a wooden raft floats on a pond. The plates are supported by a weak, plastic layer of the lower mantle called the asthenosphere. Also like a raft on a pond, the lithospheric plates are carried along by slow currents in this more fluid layer beneath them.
With an understanding of plate tectonics, geologists have put together a new history for the Earth's surface. About 200 million years ago, the plates at the Earth's surface formed a “supercontinent” called Pangaea. When this supercontinent started to tear apart because of plate movement, Pangaea first broke into two large continental masses with a newly formed sea that grew between the land areas as the depression filled with water. The southern one — which included the modern continents of South America, Africa, Australia, and Antarctica — is called Gondwanaland. The northern one — with North America, Europe, and Asia — is called Laurasia. North America tore away from Europe about 180 million years ago, forming the northern Atlantic Ocean. Some of the lithospheric plates carry ocean floor and others carry land masses or a combination of the two types. The movement of the lithospheric plates is responsible for earthquakes, volcanoes, and the Earth's largest mountain ranges. Current understanding of the interaction between different plates explains why these occur where they do. For example, the edge of the Pacific Ocean has been called the “Ring of Fire” because so many volcanic eruptions and earthquakes happen there. Before the 1960's, geologists could not explain why active volcanoes and strong earthquakes were concentrated in that region. The theory of plate tectonics gave them an answer.

The author compares the relationship between the lithosphere and the asthenosphere to which of the following?

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 the early 1800s, less than 3% of the world's population lived in cities; today, more than half of the global population is urban and by 2050, the proportion will rise to three quarters. There are thousands of small and medium-sized cities along with more than 30 megacities and sprawling, networked metropolitan areas with 15 million residents or more. Yet despite these massive transformations in how people live and interact, our international affairs are still largely dictated by national states, not cities.
       Cities are beginning to flex their muscles on the international stage. They are already displacing nation states as the central nodes of the global economy, generating close to 80% of global GDP. Cities like New York and Tokyo are bigger in GDP terms than many G-20 countries. Metropolitan regions and special economic zones are linking global cities through transnational supply chains. A growing number of mega-regions, such as those linking cities in Mexico and the U.S., transcend borders. In the process, cities are collectively forging common regional plans, trading partnerships, and infrastructure corridors.
      The spectacular rise of cities did not happen by accident. Cities channel creativity, connect human capital, and when well governed, they drive growth. That many cities and their residents are rolling up their sleeves and getting things done - where nations have failed - are grounds for optimism. In the future, we hope that it is our proximate, accountable, and empowered city leaders who will define our fates. 

Which of the following is NOT true according to the writer?

MOBILE PHONES: ARE THEY ABOUT TO TRANSFORM OUR LIVES?
We love them so much that some of us sleep with them under the pillow, yet we are increasingly concerned that we cannot escape their electronic reach. We use them to convey our most intimate secrets, yet we worry that they are a threat to our privacy. We rely on them more than the Internet to cope with modern life, yet many of us don’t believe advertisements saying we need more advanced services. Sweeping aside the doubts that many people feel about the benefits of new third generation phones and fears over the health effects of phone masts, a recent report claims that the long-term effects of new mobile technologies will be entirely positive so long as the public can be convinced to make use of them. Research about users of mobile phones reveals that the mobile has already moved beyond being a mere practical communications tool to become the backbone of modern social life, from love affairs to friendship to work.
The close relationship between user and phone is most pronounced among teenagers, the report says, who regard their mobiles as an expression of their identity. This is partly because mobiles are seen as being beyond the control of parents. But the researchers suggest that another reason may be that mobiles, especially text messaging, were seen as a way of overcoming shyness. The impact of phones, however, has been local rather than global, supporting existing friendship and networks, rather than opening users to a new broader community. Even the language of texting in one area can be incomprehensible to anybody from another area.
Among the most important benefits of using mobile phones, the report claims, will be a vastly improved mobile infrastructure, providing gains throughout the economy, and the provision of a more sophisticated location-based services for users. The report calls on government to put more effort into the delivery of services by mobile phone, with suggestion including public transport and traffic information and doctors’ text messages to remind patients of appointments. There are many possibilities. At a recent trade fair in Sweden, a mobile navigation product was launched. When the user enters a destination, a route is automatically downloaded to their mobile and presented by voices, pictures and maps as they drive. In future, these devices will also be able to plan around congestion and road works in real time. Third generation phones will also allow for remote monitoring of patients by doctors. In Britain, scientists are developing an asthma management solution using mobiles to detect early signs of an attack.
Mobile phones can be used in education. A group of teachers in Britain use third generation phones to provide fast internet service to children who live beyond the reach of terrestrial broadband services and can have no access to online information. ‘As the new generation of mobile technologies takes off, the social potential will vastly increase,’ the report argues.

Why do teenagers have such a close relationship with their mobile phones?

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:
By mid-century, there will likely be 9 billion people on the planet, consuming ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence advance? Will global warming trigger catastrophic changes, or will we be able to engineer our way out of the climate change crisis?
Making predictions is, by nature, a dicey business, but to celebrate the 40th anniversary of Smithsonian magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is our latest special series, Life in 20 50. Demographic changes in world population and population growth will certainly be dramatic. Rockefeller University mathematical biologist Joel Cohen says it's likely that by 2050 the majority of the people in the world will live in urban areas, and will have a significantly higher average age than people today. Cities theorist Richard Florida thinks urbanization trends will reinvent the education system of the United States, making our economy less real estate driven and erasing the divisions between home and work.
Large migrations from developing countries like Indonesia, Malaysia, Bangladesh, Mexico, and countries in the Middle East could disrupt western governments and harm the unity of France, Germany, Spain, the Netherlands, Poland, and the United Kingdom under the umbrella of the European Union.
And rapidly advancing technology will continue ever more rapidly. According to Bill Mitchell, the late director of MIT's Smart Cities research group, cities of the future won't look like "some sort of science -fiction fantasy" or "Star Trek" but it's likely that "discreet, unobtrusive" technological advances and information overlays, i.e. virtual reality and augmented reality, will change how we live in significant ways. Self-driving cars will make the roads safer, driving more efficient, and provide faster transports. A larger version of driverless cars-driverless trucks-may make long haul drivers obsolete.
Meanwhile, the Internet will continue to radically transform media, destroying the traditional model of what a news organization is, says author and former New York Times Public Editor, Daniel Okrent, who believes the most common kinds of news organizations in the future will be "individuals and small alliances of individuals” reporting and publishing on niche topics.

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:
Most sources of illumination generate light over an appreciable period, and indeed if an object is lit for a very brief time (1ess that 1/25 second), the human eye will not react in time to see the object. A photographic emulsion - that is, a light-sensitive coating on photographic film, paper, or glass - will, however, record much shorter bursts of light. A photographic flash can therefore be used to capture high- speed movement on film as well as to correct deficiencies of the normal surrounding lighting. Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containing magnesium wire and some oxygen-rich substance, such as potassium chlorate. When the bag was ignited, the metal burned with an intense flash. A contemporary observer reported that "this quite unsafe device seems to have done nothing worse that engulf the room in dense smoke and lead to pictures of dubious quality and odd poses.”
The evolution of the photoflash was slow, flashbulbs, containing fine wire made of a metal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920's. In the earliest type, the metal was separated from the oxygen by a thin glass bulb. The flash was fired by piercing the bulb and allowing the oxygen to come into contact with the metal, which ignited spontaneously. Later bulbs were fired by an electric battery, which heated the wire by passing a small current through it. Other combinations, such as the pairing of oxygen difluoride with zirconium, have also been used. In each case enough energy is given out to heat the oxidizable metal momentarily to a white hot emission of visible light. The smoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still glowing neighbors. A slightly bigger form of the metal will burn for a longer time.

According to the passage, an advantage of using a photoflash is that it     .

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:
Human memory, formerly believed to be rather inefficient, is really more sophisticated than that of a computer. Researchers approaching the problem from a variety of points of view have all concluded that there is a great deal more stored in our minds than has been generally supposed. Dr. Wilder Penfield, a Canadian neurosurgeon, proved that by stimulating their brains electrically, he could elicit the total recall of specific events in his subjects’ lives. Even dreams and other minor events supposedly forgotten for many years suddenly emerged in detail.
The memory trace is the term for whatever is the internal representation of the specific information about the event stored in the memory. Assumed to have been made by structural changes in the brain, the memory trace is not subject to direct observation but is rather a theoretical construct that we use to speculate about how information presented at a particular time can cause performance at a later time. Most theories include the strength of the memory trace as a variable in the degree of learning, retention, and retrieval possible for a memory. One theory is that the fantastic capacity for storage in the brain is the result of an almost unlimited combination of interconnections between brain cells, stimulated by patterns of activity. Repeated references to the same information support recall. Or, to say that another way, improved performance is the result of strengthening the chemical bonds in the memory.

How did Penfield stimulate dreams and other minor events from the past?

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:
The concept of being environmentally conscious, or “green”, has become more prevalent in twenty first-century U.S culture. It has begun to affect the manufacturing of everything from non-toxic household cleaning products to motor vehicles powered by alternative sources of energy. However, one way of being “green” that is perhaps not as apparent to the viewer but of equal importance in being environmentally conscious, is the construction of buildings that are considered “sustainable”. Sustainable buildings are those that do not impose on the environment or rely on the over-utilization of energy or natural resources. There are four main principles of sustainability, which includes consideration of the health and stability of all living things and their environmental diversity, as well as the economic opportunities of humanity.
Sustainable architecture consists of environmentally conscious design techniques. In the past, the demolition of an old building meant that all or most of the debris of the building would end up in a landfill or a waste disposal site. Today, architects can plan and design a building that uses recycled materials, such as wood, concrete, stone, or metal. These materials are salvaged from the demolition of an older building and can be appropriately incorporated into a new construction. Architects and construction supervisors may also choose to recycle more organic parts of demolished buildings, such as wooden doors, windows and other glass, ceramics, paper, and textiles.
A problem that has often arisen has been with how a site crew-whether it is demolition or construction crew determines and sorts what is “waste” and what is recyclable. Architects and environmental scientists have to decide whether or not a material is appropriate for use in new construction and how it will impact the environment. They must evaluate the materials from the demolition and determine what those materials contain, and if they meet the standards set by the U.S, government’s Environmental Protection Agency (the EPA). If the debris from the demolition contains hazardous materials that are harmful to the environment or to the consumer, such as asbestos, then the material is not salvageable. Use of the asbestos for insulation and as a form of fire retardation in buildings and fabrics was common in the nineteenth century. Asbestos was once used in shingles on the sides of buildings, as well as in the insulation in the interior walls of homes or other construction. In new “green” construction, insulation that once asbestos- based can be replaced with recycled denim or constructed with cellulose-a fibrous material found in paper products. The same-assessment applies to wood or wallboard painted with toxic lead-based paints. In addition, gas-flow regulators and meters on both water and gas heating systems constructed prior to 1961 must be carefully evaluated to determine that they do not contain dangerous substances such as mercury. Mercury can be harmful to humans and the environment if it is spilled during the removal of these devices.

You have learned about dinosaurs in school. Maybe you have seen them in museums. But how much do you really know about these animals? Not all dinosaurs were just big reptiles. For years, scientists thought dinosaurs were big, dumb, and cold blooded - in other words, just giant reptiles. Some dinosaurs were huge. But many were about the size of modern-day birds or dogs. Were dinosaurs warm- or cold blooded? Paleontologists- are not sure. But they believe some were intelligent. Of course, no dinosaur was as smart as a human or even a monkey. However, some smaller dinosaurs - like the two- meter (six-foot) Troodon — had fairly large brains.
Was Tyrannosaurus rex a powerful predator? Some scientists think the opposite is true. In the movies, T.rex is often a speedy giant, but in fact, this dinosaur could not run very fast. Physically, it was too large. In reality, T.rex probably moved as fast as an elephant. Also, T. rex had very small arms. Without strong legs or arms, this dinosaur probably wasn’t a powerful hunter. It may have been a scavenger instead, only eating animals that were already dead.
Did an asteroid kill the dinosaurs? An asteroid hit Mexico’s Yucantan Peninsula about 65 million years ago. It created a 180-kilometer (HO-mile) wide crater called Chicxulub. Many believe this asteroid caused the extinction of the dinosaurs. But even before this, dinosaurs were already dying out around the world, for many reasons. At the end of the Cretaceous period, for example, the global climate was changing and Earth's temperature was getting colder.Dinosaurs completely disappeared about 65 million years ago. However, scientists believe modern-day birds are descendants of certain dinosaurs. If this  true, then dinosaurs' relatives are still walking - and flying - among us!

In most families, conflict is more likely to be about Clothing, music, and leisure time than about more serious matters such as religion and core values. Family conflict is rarely about such major issues as adolescents' drug use and delinquency. Nevertheless, it has been estimated that in about 5 million American families (roughly 20 percent), parents and adolescents engage in intense, prolonged, unhealthy conflict. In its most serious form, this highly stressful environment is associated with a number of negative outcomes, including juvenile delinquency, moving away from home, increased school dropout rates, unplanned pregnancy, membership in religious cults, and drug abuse (Steinberg & Morris, 2001).
Many of the changes that define adolescence can lead to conflict in parent- adolescent relationships. Adolescents gain an increased capacity for logical reasoning, which leads them to demand reasons for things they previously accepted without question, and the chance to argue the other side (Maccoby, 1984). Their growing critical-thinking skills make them less likely to conform to parents' wishes the way they did in childhood. Their increasing cognitive sophistication and sense of idealism may compel them to point out logical flaws and inconsistencies in parents' positions and actions. Adolescents no longer accept their parents as unquestioned authorities. They recognize that other opinions also have merit and they are learning how to form and state their own opinions. Adolescents also tend toward ego- centrism, and may, as a result, be ultra-sensitive to a parent's casual remark. The dramatic changes of puberty and adolescence may make it difficult for parents to rely on their children's preadolescent behavior to predict future behavior. For example, adolescent children who were compliant in the past may become less willing to cooperate without what they feel is a satisfactory explanation.

There are many different metaphors used to describe culture. My favorite one is the iceberg. I think, it demonstrates so vividly what can happen to us if we believe only in the visible and ignore or underestimate the invisible part. The hidden part of our culture is that part which we know instinctively because we absorbed it from childhood on. It's handed down to us from generation to generation. We could also say, it's the "thinking" and "feeling" part of culture: habits, assumptions, attitudes, desires, values, tastes, etc.
Now, if we are in a new culture, our customary evaluations and interpretations are likely not to be on target because we see everything through our own cultural glasses. Imagine yourself in a new city trying to get around with a map from your own hometown. It wouldn't take long for you to get lost and completely frustrated! When we experience an encounter in the new culture that puzzles us, the most common reaction is to judge it through our own cultural glasses. 
I want to propose an alternate approach to our initial gut reaction. Instead of immediately and instinctively judging a situation through our own glasses, we might first just pause and notice what is happening and then realize that this is a cultural learning situation. Remember the iceberg metaphor! The new culture becomes your mirror that shows you a hidden part of your own culture. What an opportunity for personal growth and new insight! You can compare two different approaches, that of the new culture and of your own culture. This gives you a choice. Now you can decide what fits best for you or even take the best from both sides.

Ambient divers are, unlike divers who go underwater in submersible vehicles of pressure resistant suits, exposed to the pressure and temperature of the surrounding ambient water. Of all types of diving, the oldest and simplest is free diving. Free divers may use no equipment at all, but most use a face mask, foot fins, and a snorkel. Under the surface, free divers must hold their breath. Most free divers can only descend 30 to 40 feet, but some skilled divers can go as deep as 100 feet.
Scuba diving provides greater range than free diving. The word scuba stands for self-contained underwater breathing apparatus. Scuba divers wear metal tanks with compressed air or other breathing gases. When using open-circuit equipment, a scuba diver simply breathes air form the tank through a hose and releases the exhaled air into the water. A closed-circuit breathing device, also called a rebreather, filters out carbon dioxide and other harmful gases and automatically adds oxygen. This enables the diver to breathe the same air over and over. In surface-supplied diving, divers wear helmets and waterproof canvas suits. Today, sophiticated plastic helmets have replaced the heavy copper helmets used in the past.These divers get their air from a hose connected to compressors on a boat. Surface-supplied divers can go deeper than any other type of ambient diver.

When using closed-circuit devices, divers .............

Carnegie Hall, the famous concert hall in New York City, has again undergone a restoration. While this is not the first, it is certainly the most extensive in the building’s history. As a result of this new restoration, Carnegie Hall once again has the quality of sound that it had when it was first built.
Carnegie Hall owes its existence to Andrew Carnegie, the wealthy owner of a steel company in the late 1800s. The hall was finished in 1891 and quickly gained a reputation as an excellent performing arts hall where accomplished musicians gained fame. Despite its reputation, however, the concert hall suffered from several detrimental renovations over the years. During the Great Depression, when fewer people could afford to attend performances, the directors sold part of the building to commercial businesses. As a result, a coffee shop was opened in one corner of the building, for which the builders replaced the brick and terra cotta walls with windowpanes. A renovation in 1946 seriously damaged the acoustical quality of the hall when the makers of the film Carnegie Hall cut a gaping hole in the dome of the ceiling to allow for lights and air vents. The hole was later covered with short curtains and a fake ceiling, but the hall never sounded the same afterwards.
In 1960, the violinist Isaac Stern became involved in restoring the hall after a group of real estate developers unveiled plans to demolish Carnegie Hall and build a high-rise office building on the site. This threat spurred Stern to rally public support for Carnegie Hall and encourage the City of New York to buy the property. The movement was successful, and the concert hall is now owned by the city. In the current restoration, builders tested each new material for its sound qualities, and they replaced the hole in the ceiling with a dome. The builders also restored the outer walls to their original appearance and closed the coffee shop. Carnegie has never sounded better, and its prospects for the future have never looked more promising.
