In terms of sheer size, the Antarctic Desert is the largest desert on Earth, measuring a total of 13.8 million square kilometers. Antarctica is the coldest, windiest, and most isolated continent on Earth, and is considered a desert because its annual precipitation can be less than 51 mm in the interior.
 It’s covered by a permanent ice sheet that contains 90% of the Earth’s fresh water. Only 2% of the continent isn’t covered by ice, and this land is strictly along the coasts, where all the life that is associated with the land mass (i.e. penguins, seals and various species of birds) reside. The other 98% of Antarctica is covered by ice which averages 1.6 km in thickness.
There are no permanent human residents, but anywhere from 1,000 to 5,000 researchers inhabit the research stations scattered across the continent – the largest being McMurdo Station, located on the tip of Ross Island. Beyond a limited range of mammals, only certain cold-adapted species of mites, algaes, and tundra vegetation can survive there.

What is the size of the Antarctic Desert?

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:
    Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a byproduct of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it.
    Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection. Noise causes effects that the hearer cannot control and to which the body never becomes accustomed. Loud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased.
    Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America‟s number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each other.

Look at the verb accelerate in paragraph 3. Which of the following is the closest in meaning to _____.

Choose the item among A, B, C or D thai best answers the question about the passage:

"Desert is the term applied to regions of the earth that are characterized by less than 254 mm (10. inches) of annual rainfall, an evaporation rate that exceeds precipitation, and, in most cases, a high average temperature. Because of a lack of moisture in the soil and low humidity in the atmosphere, most of the sunlight penetrates to the ground. Daytime temperatures can reach 55° c (131° F) in the shade. At night the desert floor radiates heat back to the atmosphere, and the temperature can drop to near freezing. Deserts are caused by a combination of climate patterns and geological features.
 Because so little water moves through the desert soil to carry nutrients away, desert soils are naturally fertile. Crops are grown on desert lands with water provided by irrigation from rivers or wells. Such transformations of deserts are not without problems. Evaporation of the irrigation water results in the accumulation of salt on the surface soil, eventually rendering it useless for further crop production. By tapping reservoirs of fossil water deep beneath the desert, humans are, in effect, mining water. Once this water is gone, it is irreplaceable. Burning and overgrazing of semiarid lands on the periphery of deserts can irreversibly damage the plants that concentrate moisture and hold the soil together, thus enabling deserts to encroach on arable land. This encroachment, a serious world problem, is called desertification. A 1984 report of a desertification study made for the United Nations stated that 35 percent of the earth’s land surface was at least threatened by such processes."

5. What are the causes of the process of desertification?

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions:
    In the Native American Navajo nation which sprawls across four states in the American south-west, the native language is dying. Most of its speakers are middle-age or elderly. Although many students take classes in Navajo, the schools are run in English. Street sign, supermarket goods and even their own newspaper are all in English. Not surprisingly, linguists doubt that any native speakers of Navajo will remain in a hundred years' time.
    Navajo is far from alone. Half the world's 6,800 languages are likely to vanish within two generations - that's one language lost every ten days. Never before has the planet's linguistic diversity shrunk at such a pace. Isolation breeds linguistic diversity as a result, the world is peppered with languages spoken by only a few people. Only 250 languages have more than a million speakers, and at least 3,000 have fewer than 2,500. It is not necessarily these small languages that are about to disappear. Navajo is considered endangered despite having 150,000 speakers. What makes a language endangered is not that the number of speakers, but how old they are. If it is spoken by children it is relatively safe. The critically endangered languages are those that are only spoken by the elderly, according to Michael Krauss, director of the Alaska Native Language Center, in Fairbanks.
    Why do people reject the language of their parent? It begins with a crisis of confidence, when a small community finds itself alongside a larger, wealthier society, says Nicholas Ostler of Britain's Foundation for Endangered Languages, in Bath. “People lose faith in their culture” he says. "When the next generation reaches their teens, they might not want to be induced into the old tradition.” The change is not always voluntary. Quite often, governments try to kill off a minority language by banning its use in public or discouraging its use in school, all to promote national unity. The former US policy of running Indian reservation in English, for example, effectively put languages such as Navajo on the danger list. But Salikoko Mufwene, who chairs the Linguistics Department at the University of Chicago, argues that the deadliest weapon is not government policy but economic globalisation. "Native Americans have not lost pride in their language, but they have had to adapt to socio-economic pressures" he says. “They cannot refuse to speak English if most commercial activity is in English."
    However, a growing interest in cultural identity may prevent the direct predictions from coming true. ‘The key to fostering diversity is for people to learn their ancestral tongue, as well as the dominant language' says Doug Whalen, founder and president of the Endangered Language Fund in New Haven, Connecticut. “Most of these will live without a large degree of bilingualism” he says.

Choosing a career may be one of the hardest jobs you ever have, and it must be done with care. View a career as an opportunity to do something you love, not simply as a way to earn a living. Investing the time and effort to thoroughly explore your options can mean the difference between finding a stimulating and rewarding career and move from job to unsatisfying job in an attempt to find the right one. Work influences virtually every aspect of your life, from your choice of friends to where you live. Here are just a few of the factors to consider.

Deciding what matters most to you is essential to making the right decision. You may want to begin by assessing your likes, dislikes, strengths, and weaknesses. Think about the classes, hobbies, and surroundings that you find most appealing. Ask yourself questions, such as “Would you like to travel? Do you want to work with children? Are you more suited to solitary or cooperative work?” There are no right or wrong answers; only you know what is important to you. Determine which job features you require, which ones you would prefer, and which ones you cannot accept. Then rank them in order of importance to you.

Read the passage carefully and choose the correct answer.

Approximately one-third of the Earth's land surface is desert, arid land with meager rainfall that supports only sparse vegetation and a limited population of people and animals. Deserts have been portrayed as fascinating environments of adventure and exploration. These arid regions are called deserts because they are dry. They may be hot. They may be cold. They may be regions of sand or vast areas of rocks with occasional plants

Deserts are natural laboratories in which to study the interactions of wind and sometimes water on the arid surfaces of planets. They contain valuable mineral deposits that were formed in the arid environment or that were exposed by erosion. Because deserts are dry, they are ideal places for human artifacts and fossils to be preserved. Deserts are also fragile environments. The misuse of these lands is a serious and growing problem in parts of our world.

There are many animals in the desert. Some are very large, like the kangaroo or the  gazelle. Both are big and have to travel long distances for water at a spring, or an oasis.  Another fairly large animal is the addax. The addax is a desert antelope. They live in the Sahara Desert. All addaxes are herbivores. There are less than 200 of them left because of hunting and tourists. Some animals crawl along. Examples of these are snakes and  lizards. Snakes rarely drink water; they get their moisture from other prey that they eat.  So do others, like the kangaroo rat. Lizards are commonly found in the desert. They stay  out of the sun and move as little as possible. There are also other animals in the desert.  The fennec lives in northern Africa in the Sahara Desert. They are a relative of the fox.  They eat mice, small birds, lizards, and insects. When necessary, they will eat fruit. One  more desert animal is the jerboa. The jerboa is a small, long-distance jumper that lives in the desert. They are free drinking animals and they eat plants, seeds, and bugs.

The last paragraph expresses that ________.

It is not easy to choose a career today. Hundreds of students are leaving schools and universities every year  to  seek  employment  in  the  various  professions,  though  employment  opportunities  are  not  increasing proportionately. As a result, there is a lot of unemployment.   

 The inability of the various professions to absorb all those seeking employment makes the choice of a career more difficult. Before one leaves school or university, one has many plans, confident that choosing a career will not be difficult. But when, the time comes to choose a career, one finds that there are others with better qualifications waiting to enter the same profession.  Disillusioned, one then looks for  any  kind of employment.  In this way,  many  who  wanted  to  become  police  inspectors or field  assistants  in  the  rubber estates in this country,  become  teachers  instead,  and many who  wanted  to  become  teachers,  have  become shop assistants. The lack of institutions where people could acquire the skills necessary for a particular career makes the choice of a career even more difficult. For example, if one desires to become a journalist, one has to receive some training and instruction in a school of journalism. But if there is no such school, one is compelled to think of some other career.

   It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important.

   Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or on the job, whether in a kitchen or on a tractor. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, and one that should be an integral part of one's entire life.

   Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have usually been limited by the boundaries of the subject being taught.

   For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.

   Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing strip to attract the specific insect the orchid has chosen as its pollinator. To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.

   Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.
