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:
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime, they will dry faster than in winter, when the temperature is lower. The energy used in both cases to change liquid water to water vapor is supplied by heat - supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored as vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere.
In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large - scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere.

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 America, when dining, people consider it rude for a guest or dining partner to belch or burp, eat with an open mouth, smack, or lick your fingers. Napkins, generally provided are available at every meal and should be placed in one's lap and then used throughout the meal to   clean one's fingers and mouth.
It is acceptable to refuse additional servings of food by saying "No, thank you" and the host  or hostess will not be insulted if you do so. Similarly, if you leave a small amount of uneaten food on your plate at a restaurant or in a home, it is not considered an insult. If you eat everything on the plate, a host or hostess may possibly feel that they have not prepared enough food and might be embarrassed. People in the United States serve and eat food with either hand, but never take food from a communal serving dish with their hands. Generally, a serving utensil is used.
Americans typically use forks, spoons and knives to eat, but there are some types of foods that   are acceptable to eat with one's fingers, like sandwiches or pizza. When in doubt, look to see what others are doing. In formal dining situations, if you wonder whether or not it is acceptable to begin eating, you should wait until the oldest woman (or oldest man if no  women  are  present) begins to eat. When  eating, do not pick up the bowl or plate from the table to hold underneath your mouth, Even noodles, soup, and rice are eaten with the plate or bowl remaining on the table. When consuming soup and hot liquids, it is considered impolite to slurp - do not do this. When consuming noodles, twirl them around your fork and then put it in your mouth.
If you are a man taking out a woman for dinner, you are almost always expected to pay. This is for the woman to gauge your intentions and interest with her. For example, taking a woman for coffee, versus tacos, versus a fancy dinner, versus for drinks at 11:30pm, all signal many different things to them. So, the date is a -test- of many. Paying is just as important as where you take her, and how late. So, don't assume she is just trying to get a "free meal". Most girls aren't. Also, if you are going out with a friend to eat, almost always, the bill is expected to be split in half, or each person pays for themselves.
If you are eating in a restaurant, you will be expected to add a 15 to 20 % tip for the server to  your bill. In America, wait staff might occasionally stop by your table to ask how your meal is, which is considered good service. They will also bring you your check when it seems reasonable that you are finished with your meal, however this is not necessarily an indication that you must leave right away (Do not be too embarrassed to ask for the check either waiters and waitresses cannot read minds.) Take your time to finish your meal, and unless there is a line of people waiting at the door, it is not considered  rude to linger at your table for as long as you like.

When will the bill be divided for the people having the meal?

U.N. diplomats abandoned efforts to draft a treaty that would outlaw human cloning. They will likely settle for a weaker statement, and won’t seek a widespread ban, officials said. The debate began when Italy introduced a document into the UN. to stop any attempt at cloning human life. The Belgians objected to the use of the term “human life” in the document, because they feared it would put a stop to all forms of human cloning.
[1] There is near universal support among the United Nations’ 191 members for a ban on reproductive cloning-creating cloned babies. [2] Many countries have wrestled over whether to allow cloning for stem cell and other types of research. [3] Indeed, many researchers believe that stem cells could be used to repair nerve tissue or cure diseases, including Alzheimer’s. [4] Stem cells are taken from embryos and cloned, but extracting these cells kills the embryo. Opponents say that this is equal to murder.

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 desert animals will drink water if confronted with it, but many of them never have any opportunity. All living things must have water, or they will expire. The herbivores find it in desert plants.
The carnivores slake their thirst with the flesh and blood of living prey. One of the most remarkable adjustments, however, has been made by the tiny kangaroo rat, who not only lives without drinking but subsists on a diet of dry seeds containing about 5% free water. Like other animals, he has the ability to manufacture water in his body by a metabolic conversion of carbohydrates. But he is notable for the parsimony with which he conserves his small supply by every possible means, expending only  minuscule amounts in his excreta and through evaporation from his respiratory tract.
Investigation into how the kangaroo rat can live without drinking water has involved various experiments with these small animals. Could kangaroo rats somehow store water in their bodies and slowly utilize these resources in the long periods when no free water is available from dew or rain? The simplest way to settle this question was to determine the total water content in the animals to see if it decreases as they are kept for long periods on a dry diet. If they slowly use up their water, the body should become increasingly dehydrated, and if they begin with a store of water, this should be evident from an initial high water content. Results of such experiments with kangaroo rats on dry diets for more than 7 weeks showed that the rats maintained their body weight. There was no trend toward a decrease in water content during the long period of water deprivation. When the kangaroo rats were given free access to water, they did not drink water. They did nibble on small pieces of watermelon, but this did not change appreciably the water itent in their bodies, which remained at 66.3 % to 67.2 % during this period. This is very close to the water content of dry-fed animals (66.5 %), and the availability of free water, therefore, did not lead to any “storage” that could be meaningful as a water reserve. This makes it reasonable to conclude that physiological storage of water is not a factor in the kangaroo rat’s ability to live on dry food.

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 number of factors related to the voice reveal the personality of the speaker. The first is the broad area of communication, which includes imparting information by use of language, communicating with a group or an individual and specialized communication through performance. Aperson conveys thoughts and ideas through choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, by the rhythm that is inherent within the language itself, and by speech rhythms that are flowing and regular or uneven and hesitant, and finally, by the pitch and melody of the utterance. When speaking before a group, a person’s tone may indicate uncertainty or fright, confidence or calm. At interpersonal levels, the tone may reflect ideas and feelings over and above the words chosen, or may believe them.Here the participant’s tone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack of concern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are usually discernible by the acute listener. Public performance is a manner of communication that is highly specialized with its own techniques for obtaining effects by voice and /or gesture. The motivation derived from the text, and in the case of singing, the music, in combination with the performer’s skills, personality, and ability to create empathy will determine the success of artistic, political, or pedagogic communication. Second, the voice gives psychological clues to a person’s self-image, perception of others, and emotional health. Self- image can be indicated by a tone of voice that is confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a few personality traits. Also the sound may give a clue to the facade or mask of that person, for example, a shy person hiding behind an overconfident front. How a speaker perceives the listener’s receptiveness, interest, or sympathy in any given conversation can drastically alter the tone of presentation, by encouraging or discouraging the speaker. Emotional health is evidenced in the voice by free and melodic sounds of the happy, by constricted and harsh sound of the angry, and by dull and lethargic qualities of the depressed.

According to the passage, an overconfident front may hide    .

Life expectancy is the period of time that a person can expect to live. Life expectancy varies greatly between genders and cultures. It used to be that women had a lower life expectancy than men (1 in every 4 women died in childbirth), but now they live an average of four to five years longer than men. Life expectancy has been increasing rapidly over the last centuries. With the advent of such modern miracles as sewers, medicine and a greater understanding of how diseases are spread, our life expectancy has increased by 25-30 years.
In developing countries like Swaziland, where there is a high HIV/ AIDS rate, life expectancy is as low as 32.6 years. In developed countries like Australia, life expectancy rates are as high as 81 years. There are an increasing number of factors which can cancel out the disadvantages you have. The one that we are looking at now is how your career can affect your life expectancy. Choosing the wrong career can result in a shorter life!
If you want your career to positively influence your life expectancy, you have to be made of money. That's right. Rich people in wealthy areas of England and France live 10 years longer than the people in poorer areas. Having a successful career has its drawbacks, too if the result of hard work is stress.
Stress can lead to a number of psychological disorders such as depression, anxiety, fatigue, tension and aggression. These conditions may result in a lack of concentration and an increase in serious injuries at work. They can also lead to high blood pressure and heart attacks which seriously affect life expectancy.
If you are worried that your job might decrease your life expectancy, you probably need to avoid careers on "dangerous jobs" list such as timber cutters, pilots, construction workers, roofer, truck drivers.
So if you don't want to kick the bucket at an early age, choose a career in something other than timber cutting, but above all, remember to relax.

In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.
Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.

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:
Diversity is a hallmark of life, an intrinsic feature of living systems in the natural world. The demonstration and celebration of this diversity is an endless rite. Look at the popularity of museums, zoos, aquariums and botanic gardens. The odder the exhibit, the more different it is from the most common and familiar life forms around us, the more successful it is likely to be. Nature does not tire of providing oddities for people who look for them. Biologists have already formally classified 1.7 million species. As many as 30 to 40 million more may remain to be classified. (1)
Most people seem to take diversity for granted. If they think about it at all they assume it exists in endless supply. Nevertheless, diversity is endangered as never before in its history. Advocates of perpetual economic growth treat living species as expendable. As a result an extinction crisis of unprecedented magnitude is under way. Worse yet, when diversity needs help most, it is neglected and misunderstood by much of the scientific community that once championed it. (2)
Of the two great challenges to the legitimacy of this diversity, the familiar one comes primarily from economists. Their argument, associated with such names as Julian Simon, Malcolm McPherson and the late Herman Kahn, can be paraphrased: "First, if endangered species have a value as resources - which has been greatly exaggerated - then we should be able to quantify that value so that we can make unbiased, objective decisions about which species, if any, we should bother to save, and how much the effort is worth. Secondly, the global threat to the diversity of species, particularly in the tropics, has been overestimated. Thirdly, we have good substitutes for the species and ecosystems that are being lost, and these substitutes will nullify the damage caused by the extinctions". (3)
The structure of the argument seems to me to be identical in form to that of an old joke from the American vaudeville circuit. One elderly lady complained to another about her recent vacation at a resort in the Catskill Mountains in New York State. "The food was terrible", she moaned. "Pure poison, I couldn't eat a bite. And the portions were so tiny!" (4)
Species may be valuable, but not especially so, and the threat to them has been exaggerated. But this does not matter anyway, say the economists, because we can replace any species that vanishes.(5) 
It is not clear how much of an impact this argument has on the informed public, but it has certainly provoked an outcry among scientific conservationists. It has set the terms for, and dominated, most of the pro-diversity literature of the past few years, making it a literature of response, thus limiting its scope and creative force.

In 1826, a Frenchman named Niépce needed pictures for his business. He was not a good artist, so he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph.
The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything clearly, even the smallest details. This kind of photograph was called a daguerreotype.
Soon, other people began to use Daguerre's process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities, and mountains.
In about 1840, the process was improved. Then photographers could take pictures of people and moving things. The process was not simple and photographers had to carry lots of film and processing equipment. However, this did not stop photographers, especially in the United States. After 1840, daguerreotype artists were popular in most cities.
Matthew Brady was one well-known American photographer. He took many portraits of famous people. The portraits were unusual because they were lifelike and full of personality. Brady was also the first person to take pictures of a war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible.
In the 1880s, new inventions began to change photography. Photographers could buy film ready- made in rolls, instead of having to make the film themselves. Also, they did not have to process the film immediately. They could bring it back to their studios and develop it later. They did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With a small camera, anyone could be a photographer. People began to use cameras just for fun.
They took pictures of their families, friends, and favorite places. They called these pictures "snapshots".
Documentary photographs became popular in newspapers in the 1890s. Soon magazines and books also used them. These pictures showed true events and people. They were much more real than drawings.
Some people began to think of photography as a form of art. They thought that photographycould do more than show the real world. It could also show ideas and feelings, like other art forms.

She wants to be a singer; you think she should go for a long–term career with job security and eventually retire with a good pension. But a new report suggests that in fact she’s the practical one. Why do parents make terrible career advisers?
Today’s 14 and 15–year–olds are ambitious. They are optimistic about their prospects, but their career ideas are rather vague. Although 80% of them have no intention of following in their parents’ footsteps, 69% still turn to their parents for advice. They look at their working future in a different way to their parents.
A job for life is not in their vocabulary; neither is a dead–end but secure job that is boring but pays the bills. Almost half the boys surveyed expected that their hobbies would lead them into the right sort of job, while most girls seemed determined to avoid traditionally female careers such as nursing.
In the past, this might have counted as bad news. Certainly when I was 15, my guidance counsellors were horrified at my plans to become a writer. I’m glad I didn’t change my plans to suit them. Even so, their faith in rigid career paths was well–founded. In those days, that was the way to get ahead.
But the world has changed. The global economy is not kind to yesterday’s diligent and dependable worker. The future belongs to quick–thinking people who are resourceful, ambitious and can take the initiative. This means that a 14–year–old who sees her working future as a kind of adventure, to be made up as she goes along is not necessarily being unrealistic.
However, she has to have the training and guidance to help her develop the right skills for today’s market; not the rigid preparation for a workplace that disappeared twenty years ago. Many young people are very aware of the pitfalls of the flexible workplace; they understand that redundancy, downsizing and freelancing are all part of modern working life, but no one is telling them how they might be able to turn the new rules of the employment game to their advantage. This is what they need to know if they are to make a life for themselves.

So what is to be done? A good first step would be to change the way in which schools prepare young people for adult life. The education system is becoming less flexible and more obsessed with traditional skills at just the time that the employment market is going in the opposite direction.
Accurate, up–to–date information on new jobs and qualifications can help guidance counsellors to help their students. Young people need solid information on the sort of training they need to pursue the career of their dreams. Also, a little bit of encouragement can go a long way. If nothing else, a bit of optimism from an adult can serve as an antidote to the constant criticism of teenagers in the press.
What, then, can we as parents do to help them? The best thing is to forget all the advice that your parents gave you, and step into your teenager’s shoes. Once you’ve done that, it’s easier to see how important it is that they learn how to be independent, resourceful and resilient. Give them the courage to follow their dreams –however odd they might sound right now. In a world that offers economic security to almost no one, imagination is a terrible thing to waste.

The writer uses the phrase “aware of the pitfalls” to show that young people     .

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:
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime, they will dry faster than in winter, when the temperature is lower. The energy used in both cases to change liquid water to water vapor is supplied by heat - supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored as vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere.
In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large - scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere.

It can be inferred from the passage that terra-cotta had which of the following advantages?
