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.

How many researchers inhabit this cold 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. 
Long gone but not forgotten are those carefree student days of shared showers, derelict rental properties and parties where the booze always ran out before midnight. Being a student was quite a privilege in the good old days when local authorities and the government footed the bill and there was almost certainly a job at the end of it.
In the early 1960s, only 4% of school leavers went to university, rising to around 14% by the end of the 1970s. Nowadays, more than 40% of young people start undergraduate degrees – but it comes at a cost. Today’s students leave with debts of £40,000 and upwards to pay back over their working lives.
So how has the student experience changed over the years? Parents looking back on their university lives are amazed at the luxuries their sons and daughters enjoy, such as en suite bathrooms, flatscreen TVs and leather sofas. Student accommodation has improved but rents have soared and take up a bigger whack of the living cost loans, leaving today’s undergraduates little better off than their parents.
They still party and have a good time, but students are working harder and more consistently, their parents believe. Partly, it is the move away from “big bang” finals to continuous assessment, they say, but also the pressure to get that all-important 2:1 or above degree classification. One-third of students were awarded firsts or 2:1s in 1970. Last year it was over two-thirds: 70%.
Today’s students are more career-orientated and under pressure to take on extracurricular activities, more responsibilities and work experience to compete in the graduate jobs market. Meeting people, making friends for life and discovering new interests: these are the things that have not changed for students who are following the same route to independence as their parents.

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.

One must find that ________.

   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.

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 word They in paragraph 2 refers to ________.

     Many of us worry about the effects of television on family life. We think that we spend too much time watching television and that it takes us away from more important activities, such as reading, exercising and talking to family and friends. But is this really true? 
      Studies have shown that people in the United States do spend a lot of time in front of their television sets. About 98% of American homes have at least one TV set, and in the average home the TV is on more than six hours a day. But how much attention do people actually pay to the programs? And do people who watch TV really spend less time on other free-time activities? Recently some researchers in New York City tried to find the answers to these questions by conducting a telephone survey. They phoned more than a thousand people all over the United States and asked them questions about how they spend their free time.
      No one was surprised to find out that watching TV is the most popular free-time activity in the United States. More than 70% of those asked said that they watch TV every day or almost every day. The second most popular activity that they mentioned was reading the newspaper. Listening to music at home was third, talking on the phone to friends and relatives was fourth and doing some form of exercise was fifth. 
      But the researchers discovered an interesting fact about Americans' TV habits. According to this survey, although most people turn the TV on every day, they do not actually watch it very much. Six out of ten people said that when the TV is on, they seldom pay attention to it. During a typical television program, they may eat dinner, do housework, read a newspaper or magazine, talk to their children or even read to them. The TV may be on, but it is just background music.
      The researchers therefore concluded that television does not take Americans away from more important activities. It doesn't keep them from doing other free-time activities. In fact, when they compared people who frequently watch TV and those who seldom watch TV, they found that there were no great differences in their other activities. The frequent watchers read to their children and talk to their families just as much as the others.

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.

If you’ve done any traveling at all, you’re likely quite aware that customs and etiquette differ from one culture to another: what may be perfectly innocuous in one place may be hideously offensive in another, and vice-versa. Granted, even if you haven’t traveled at all, you’re probably aware of the fact that certain types of behavior aren’t exactly acceptable in other countries: belching at the table may be a sign of gratitude in some places, but in most areas of North America and Europe, such a display will earn you a fair bit of ire. Whether you plan on traveling to any of the places listed below or just doing business with a foreign client, it’s important to educate yourself on the standards of politesse and etiquette beforehand—the last thing you want to do is offend someone with any ignorant, boorish behavior. Here’s how to be polite in different countries.
When dealing with Japanese clients, be sure to dress fairly conservatively, and make sure that you bow lower than they do upon meeting them. Accept gifts with both hands and open them later, not in front of the giver, and never blow your nose at the dining table. Avoid asking and answering direct questions: it’s better to imply rather than ask, and to answer with vagueness during conversations.
In Mexico, when meeting others, women should initiate handshakes with men, but all people should avoid making too much eye contact; that can be seen as aggressive and belligerent behavior. If sharing a meal with others, keep your elbows off the table and try to avoid burping at all costs. Keep your hands off your hips, and make sure you never make the “okay” sign with your hand: it’s vulgar.
In Kenya, when greeting someone older or of a higher status than yourself, grip their right wrist with your left hand while shaking it; it’s a sign of respect and deference. Do ask questions about their health, family, business etc. before getting to major topics, as skipping these niceties is seen as impolite. If sharing meals, do not begin eating until the eldest male has been served and starts to eat.
Turning down an alcoholic drink is considered terribly offensive in Russia, so it’s a good idea to fortify yourself with some greasy food before heading out for a meal with Russian or Ukrainian clients. Don’t smile at strangers or they’ll think you’re deranged, and when paying for items, place your money on the counter rather than trying to hand it directly to the cashier.

According to the passage, which of the following behavior should be avoided when sharing meals with others?

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.
There are many theories of aging, but virtually all fall into the category of hypotheses with a minimum of supporting evidence. One viewpoint is that aging occurs as the body's organ systems become less efficient. Thus failures in the immune system, hormonal system, and nervous system could all produce characteristics that we associate with aging. Following a different vein, many current researchers are looking for evidence at the cellular and sub cellular level. It has been shown that cells such as human fibroblasts (generalized tissue cells) grown in culture divide only a limited number of times and then die. Only cancer cells seem immortal in this respect. Fibroblast cells from an embryo divide more times than those taken from an adult. Thus some researchers believe that aging occurs at the cellular level and is part of the cell's genetic makeup. Any event that disturbs the cell's genetic machinery such as mutation, damaging chemicals in the cell's environment, or loss of genetic material, could cause cells to lose their ability to divide and thus bring on aging. Other theories of aging look at different processes. 
Chronological aging refers to the passage of time since birth and is usually measured in years. While chronological age can be useful in estimating the average status of a large group of people, it is a poor indicator of an individual person's status because there is a tremendous amount of variation from one individual to the next in regard to the rate at which biological age changes occur. For example, on the average, aging results in people losing much of their ability to perform strenuous activities, yet some elderly individuals are excellent marathon runners.
Another type of aging is cosmetic aging, which consists of changes in outward appearance with advancing age. This includes changes in the body and changes in other aspects of a person's appearance, such as the style of hair and clothing, the type of eyeglasses, and the use of a hearing aid. Like chronological aging, it is frequently used to estimate the degree to which other types of aging have occurred. However, it is an inaccurate indicator for either purpose because of variation among individuals and because a person's appearance is affected by many factors that are not part of aging, including illness, poor nutrition, and exposure to sunlight.

"The deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay or small stones. They are not flat, either; they often have high hills and deep valleys. There is some plant life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants. The deserts of the world are not uninhabited. People also live outside oases, but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.
 The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, put them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable. No man in the desert would ever refuse to give a stranger food and water."

   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.
