Read the following passage and choose the best answer (A, B, C, D):
My children can’t live without media. At age 14, 15 and 18, my daughters Sussy and Anni and my son Bill don’t use media. They inhabit media. And they do so exactly as fish inhabit a pond. Gracefully, and without consciousness and curiosity as to how they got there. They don’t remember a time before email or instant messaging or Google. When my children laugh, they don’t say “Ha, ha”. They say “LOL”. These are children who shrug indifferently when they lose their iPods, with all 5000 tunes plus video clips, feature films, and TV shows (like who watches TV on a television anymore?). “There is plenty more where that came from”, their attitude says. And they seem right. The digital content that powers their world can never truly be destroyed. As a social scientist, journalist, and mother, I’ve always been an enthusiastic user of information technology. But I’d noticed that the more we seemed to communicate as individuals, the less we seemed to function together as a family. And on a broader scale, that the more facts we have at our fingertips, the less we seem to know. That the “convenience” of messaging media (email, SMS, IM) consumes ever larger amounts of our time. That as a culture we are practically swimming in entertainment, yet remain more depressed than any people who have ever lived. Our family’s self-imposed exile from the information age changed our lives infinitely for the better. I watched as my children became more focused. I watched as their attention spans increased, allowing them to read for hours at a time; to hold longer and more complex conversations with adults and among themselves. They probably did no more homework during The Experiment than they had done before, but they all completed it far more efficiently and far more quickly The Experiment also forced us to notice food more. Before, eating had been a side dish. Now it was the main course, or at least one of them. Our approach to cooking changed, too, especially for the girls. They’d started out as reasonably competent cooks, but by the end of The Experiment they were capable of turning out entire meals with ease The Experiment also confirmed my strong suspicion that media has been robbing Sussy of sleep for years. Unplugged, the changes to her sleep patterns were dramatic. The evidence strongly suggests she is no isolated case. One study found that children who spend more time online also drink more caffeinated beverages, with a resulting effect on their prospects of sleeping well

Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on. “It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. One- third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? "Sugar, we believe, is one of the culprits, if not the major culprit," says Johnson. Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us. So what is the solution? It’s obvious that we need to eat less sugar. The trouble is, in today’s world, it’s extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat. But there are those who are fighting back against sugar. Many schools are replacing sugary desserts with healthier options like fruit. Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.

Scientist and inventor George Washington Carver was born into slavery during the American Civil War. After the war, he worked diligently to get an education. He managed to get an advanced degree in Botany, which is the study of plants. After he finished his college degree, he worked in the South. He taught people about botany and about how it could be used to improve farming. Carver learned that there was a problem with cotton farming in the South. Cotton takes nutrients from the soil. If cotton is planted year after year, the quality of the soil decreases. Carver knew that plants like peanuts and sweet potatoes are different from cotton. They add nutrients to the soil rather than take nutrients from the soil. Carver told farmers that it was a bad idea to grow only cotton and no other crops each year. He told them that they should also grow plants like peanuts and sweet potatoes, which improve the quality of the soil. Many farmers followed the advice that Carver offered them. The result was that the production on their farms increased. This increased production of peanuts and sweet potatoes improved the quality of the soil. However, when production of peanuts and sweet potatoes increased, a new problem developed. The new problem was that there were too much peanuts and sweet potatoes. To solve this problem, Carver began working in a laboratory to find new uses for peanuts and sweet potatoes. He developed hundreds of products that could be made from peanuts and sweet potatoes. These hundreds of products included food products, medicines, plastics and fertilizer

Most people think that lions only come from Africa. This is understandable because in fact most lions do come from there but this has not always been the case. If we went back ten thousand years, we would find that there were lions roaming vast sections of the globe. However now, unfortunately only a very small section of the lion's former habitat remains.
Asiatic lions are sub-species of African lions. It is almost a hundred thousand years since the Asiatic lions split off and developed as a sub-species. At one time the Asiatic lion was living as far west as Greece and they were found from there, but in a band that spreads east through various countries of the Middle East, all the way to India. In museums now, you can see Greek coins thathave clear images of the Asiatic lion on them. Most of them are dated at around 500 B.C. However, Europe saw its last Asiatic lions roaming free two thousand years ago. Over the next nineteen hundred years the numbers of Asiatic lions in the other areas declined steadily, but it was only in the nineteenth century that they disappeared from everywhere but in India.
The Gir Wildlife Sanctuary in India was established especially to protect the Asiatic lion. There are now around three hundred Asiatic lions in India and almost all of them are in this sanctuary. However, despite living in a sanctuary, which makes them safe from hunters, they still face a number of problems that threaten their survival. One of these is the ever-present danger of disease. This is what killed more than a third of Africa’s Serengeti lions in 1994, and people are fearful that something similar could happen in the Gir Sanctuary and kill off many of the Asiatic lions there.
India's lions are particular vulnerable because they have a limited gene pool. The reason for this is interesting is because all of them are descended from a few dozen lions that were saved by a prince who took a particular interest in them. He was very healthy, and he managed to protect them; otherwise they would probably have died out completely.
When you see the Asiatic lion in India, what you sense is enormous vitality. They are very impressive animals and you would never guess that they have this vulnerability when you look at them.tatements are correct EXCEPT that .

Read the following passage and choose the best answer (A, B, C, D):
By the end of the third millennium, people will all have access to basic utilities like electricity and the internet. As a type of civilization, the overall energy consumption of everyone in the 30th century will be at a level of around 4×10²⁶ watts. In other words, the energy utilization in a world full of working class consumers will be comparable to the luminosity of our parent star. So, the people of the future will inevitably need to fully harness the output of the Sun through the use of a vast array of satellite mega-structures that encircle the celestial body and capture the radiation it emits. In requiring everyone to work together, the inclusive attitude of the future will cause everyone to grow much closer to one another, improving interpersonal relationships in neighborhoods the world over. By the year 3000, the whole of humanity will become a sort of poly-amorous society of mono-ethnic global citizens, living in a complex egalitarian intercontinental cooperative. Everyone will be part of multicultural communities within communities. Companies and credit unions will even be owned by their employees. People will all be very conscientious. Everyone will support the global economy, as well as ecology, of the world. Humans will inhabit artificial urban jungles filled with buildings and sidewalks, while the other animals will inhabit natural rural jungles filled with wilderness and trails. Friends will walk through the crowded streets of the mega-cities of the future holding hands with one another. Public displays of affection will be customary among everyone. Casual bisexual encounters will be the norm. Everyone will care about everyone else. People will all accept each other, and help each other out, more and more as time goes on. The point is that eventually, everyone will finally get along. Humanity will progress to a point of collective compatibility as everyone sufficiently integrates and assimilates. From now until the year 3000, the several thousand languages currently spoken will reduce down to only about a hundred. More importantly, the nation-state members of the UN will all use the same form of electronic currency. As the countries of the world unify more and more, the metric system will become the universal standard of measurement. Things will become increasingly more common among everyone. This will bring everyone closer and closer together, each step of the way. In the end, cultural memes will all eventually just blend together in the great melting pot that is the world. People will also change physically, along with mentally, too though. For instance, there will be an increase in both height and longevity, among people in general. In the year 3000 people will be about six feet tall, and live to be 120 years old, on average. They will experience a slight reduction in the size of their mouths, too. Improvements in nutritional science will revolutionize the world of medicine and alter the course of human evolution. Everyone will be genetically screened as an embryo to weed out defects and correct mistakes in their personal genome. 8th scale transhuman cyborgs will even go so far as to have 7 th scale robotic integrations, with microscopic machines making them better. This will be terribly important because there will be very little diversity in the gene pool of the superhumans of the future, who are all bred to be what is considered ideal.

Read the following passage and choose the best answer (A, B, C, D):
The British are particular about timings and being late is frowned upon, but being on time is a complicated matter because in some situations, being a few minutes early on others means being exactly on time and in some instances, it is completely acceptable to arrive 10 minutes to a few hours later than the stated time. This can be a minefield for someone who is new to the UK, so here are some basics rules that will help you get your timings right whatever the situation. In formal meetings, such as job interviews, you should arrive at least five minutes before your meeting. This will give you time to compose yourself before your big meeting. In the UK, arriving late for a formal meeting is seen as unprofessional and will reflect badly on you. If you are running late, ring your host to let them know you will be late. On arrival, apologize sincerely and offer a reason for your lateness, such as you got lost or the train was delayed. It will help you redeem yourself. However, if you are late because you set off later than you should have, it’s wise to keep that to yourself! With appointments such as visits to the doctor or dentist, the time you are given for your appointment isn’t necessarily the time you will be seen. It is not uncommon you may have to wait between 15-30 minutes before you are seen by a doctor and that can be much longer if it is a hospital appointment. Nevertheless, you should arrive at least five minutes before your appointment and it is recommended you take a drink and something to read. When you start a new job, you are given your typical working hours. For example, if you are expected to start at 9am, it is not acceptable to arrive after this time. Most employers make an exception if you are late once in a while. If you have an appointment, you need to seek permission from your employer to arrive later on that day. Being late consistently will land you in trouble and you can be sacked from your job if after three warnings you are still late. There is an unsaid rule that you can be a few minutes late for a lecture or seminar once in a while. When you are late, you should enter quietly and find a seat at the back of the room. At the end of lecture or seminar, you should offer your apology to the lecturer. If you have been invited to a dinner party, you should arrive exactly on time as the host will have planned when they will serve the food. You will find that your host will serve their guests a pre-dinner drink, so that gives you a bit of wiggle room, but if you are running later than 10 minutes, you should ring your host and let them know how late you might be. That way they can decide whether to go ahead and serve the other guests. When you arrive you should offer the host and the other guests your apology for being late.
3. According to the second paragraph, what kind of reasons should you offer when you come late for a job interview? -
Read the following passage and choose the best answer (A, B, C, D):
Christmas is around the corner, which means it’s about time you examined carefully your holiday gift list. “Choosing the wrong gift can be kind of risky for relationships because it implies that you and the receiver don’t have anything in common,” says Elizabeth Dunn, a psychology professor at the University of British Columbia in Canada. Her research has also showed that undesirable gifts can sometimes negatively impact the receiver’s perception of a relationship’s future potential. Since you don’t want your holiday gift to cause more harm than good, how can you be sure to choose a gift the receiver will love? Psychology may have the answer. Contrary to common belief, studies have actually shown that spending more does not always guarantee a well-received gift. “It seems quite self-evident to most of us that if you spend more, you’re going to get a better girl. But as it turns out, there’s no evidence that recipients associate the cost of a gift with how much they enjoy that gift,” says Jeff Galak, an associate professor of marketing at the Carnegie Mellon Tepper School of Business in the US city of Pittsburgh. Galak acknowledges that your gift may have to hit a certain price due to tradition or expectations. “But once you meet that cost, it doesn’t matter at all if you buy something even more valuable than that limit,” he says. Galak says the trick for giving a great and unforgettable gift is to think past the moment of handing it over. “When most givers give gifts, they try to make the moment they give the gift perfect and want to see the smile on recipient’s face right in that moment,” says Galak. “But in reality, what most recipients really love about a gift is how much value they’re going to derive from it over an extended time period.” In other words, it might be exciting to watch a friend open a gift of a concert ticket, but since it’s a gift that cannot be enjoyed over time, it may soon be forgotten. It is also suggested that if you can’t think of a good gift, just ask the recipient what they want. “People want to be creative and surprise the recipient,” says Dunn. “but the better gift will be whatever it is they say they like.” At the end of the day, don’t fret too much about giving a terrible gift. Unless something is wildly inappropriate, the recipient will fell some level of appreciation. Galak says that over the course of his research he has asked thousands of participants about gifts they have received, and he rarely hears someone talk about a bad girl. And even if you do give a sub-standard gift to someone you are close to you may be saved by your thoughtfulness. “When someone does something puzzling that needs to be explained – like give a bad gift – that’s when you think about what’s on the other person’s mind,” says Nicholas Epley, a professor at the University of Chicago Booth School of Business. His research shows that if your recipient feels like you at least spent a lot of time making your selection, they’ll appreciate the effort that went into choosing a less desirable gift. In other words, the old saying ‘it’s the thought that counts’ really might be true.

The dramatic growth of the world's population in the twentieth century was on a scale without parallel in human history. Most of this growth had occurred since 1950 and was known as the population 'explosion'. Between 1950 and 1980 the world population increased from 2.5 to over 4 billion, and by the end of the twenty century the figure had risen to about 6.6 billion. Growth of this size cannot continue indefinitely. Recent forecasts suggest that the total population will level out at between 10 and 15 billion in the mid twenty first century. Already there are encouraging signs that the rate of increase in many less developed countries is beginning to slow down.
The phrasal verb 'level out' in line 8 means ______.

Of the six outer planets, Mars, commonly called the red planet, is the closest to Earth. Mars, 4,200 miles in diameter and 55 percent of the size of Earth, is 34,600,000 miles from Earth, and 141,000,000 miles from the Sun. It takes this planet, along with its two moons, Phobos and Deimos, 1.88 years to circle the Sun, compared to 365 days for the Earth.
For many years, Mars had been thought of as the planet with the man-made canals, supposedly discovered by an Italian astronomer, Schiaparelli, in 1877. With the United States spacecraft Viking I's landing on Mars in 1976, the man-made canal theory was proven to be only a myth.
Viking I, after landing on the soil of Mars, performed many scientific experiments and took numerous pictures. The pictures showed that the red color of the planet is due to the reddish, rocky Martian soil. No biological life was found, though it had been speculated by many scientists. The Viking also monitored many weather changes including violent dust storms. Some water vapor, polar ice, and permafrost (frost below the surface) were found, indicating that at one time there were significant quantities of water on this distant planet. Evidence collected by the spacecraft shows some present volcanic action, though the volcanoes are believed to be dormant, if not extinct.

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.
As viewed from space, Earth’s distinguishing characteristics are its blue waters and white clouds. Enveloped by an ocean of air consisting of 78% nitrogen and 21% oxygen, the planet is the only one in our solar system known to harbor life. Circling the Sun at an average distance of 149 million kilometers (93 million miles), Earth is the third planet from the Sun and the fifth largest planet in the solar system.
Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field which, coupled the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors as well, most of which burn up in the Earth’s atmosphere before they can strike the surface. The planet active geological processes have left no evidence of the ancient pelting it almost certainly received soon after it formed about 4.6 billion years ago. The Earth has a single natural satellite – the moon.

Next time your boss asks you to work late and miss your band rehearsal or board game night, point them to a new study in the Journal of Vocational Behavior. Researchers have found that spending more time on a hobby can boost people’s confidence in their ability to perform their job well. Ciara Kelly at Sheffield University and colleagues recruited 129 hobbyists — from amateur climbers to improv comedians — to look at how the time spent on their hobbies shaped their work life. To begin with, the team measured the seriousness of each participant’s hobby, asking them to rate their agreement with statements like “I regularly train for this activity”, and also assessed how similar the demands of their job and hobby were. Then, each month for seven months, participants recorded how many hours they had dedicated to their activity, and completed a scale measuring their belief in their ability to effectively do their job, or their “self-efficacy”, in which they rated themselves on statements like “At work I am able to successfully overcome many challenges”. The researchers found that when participants spent longer than normal doing their leisure activity, their belief in their ability to perform their job increased. But this was only the case when they had a serious hobby that was dissimilar to their job, or when their hobby was similar to their work but they only did it casually. When their hobby was both serious and similar to their job, then spending more time on it actually had a detrimental effect, decreasing their self-efficacy. Why might that be? To maintain a serious hobby, people need to invest significant psychological resources, so if the activity has the same kinds of demands as their work, they may be left drained and unable to perform as well at their job. But if their hobby is quite different from their career, it may not interfere in the same way but instead help them develop other knowledge and skills that can boost their confidence at work. Of course, the data don’t provide conclusive evidence about the direction of the effect. Still, the results suggest that companies may want to encourage employees to pursue interests outside of work, as long as those activities differ from their day-to-day tasks. And they also may give pause to those who dream of packing it all in and turning their hobby into a career.

Globalization can be seen as increased economic, cultural and technological exchange between countries. Examples might be McDonald's in Calcutta and Japanese motor technology in Britain. Many international organizations are pro-globalization, while many others are anti- ones. The main organizations against globalization are the environmental organizations, such as Friends of the Earth and reenpeace, who put forward the belief that globalization harms the environment. In general, these organizations blame global corporations for global warning and the depletion of natural resources. The most obvious is oil and gas, but there are others such as tropical rainforests, which are cut down for timber, and the resources of the sea, which may be affected by pollution. Organizations which represent developing countries, including international aid agencies such as Oxfam, are also against globalization. They are concerned that the global organizations, such as the International Monetary Fund (IMF) and the World Bank, are not doing enough to help the poor and indeed, may be adding to their problems. Some are critical of the World Trade Organization (WTO). They argue that the WTO is making difficult for poor countries to protect and build their own industries. On the contrary, many organizations are in favor of globalization. Perhaps the most important one is the WTO. This organization was set up in 1995 and has 123 member countries. It administers the rules of international trade agreed by its member countries. The WTO's rules make it difficult for a country to favor their own industry over imports from other countries. The WTO argues that the growth of trade between countries increases the wealth of everyone. Trade allows those who can produce goods most cheaply to do so, thus giving everyone the best possible price. Another pro-globalization organization is IMF. This was established after World War II in 1946. It aims to promote international cooperation on finance and provide temporary help for countries suffering financial problems. The IMF has 182 member countries. Finally, the United Nations, which was established after the Second World War, has become a promoter of globalization. It aims to promote a shared set of values in the areas of labour standards, human rights and environmental practices between the UN and the business community.

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:
Accustomed though we are to speaking of the films made before 1927 as “silent”, the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film.
As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before the y were to be shown (if, indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry.
To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications of mood as “pleasant’, “sad”, “lively”. The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next.Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D. w. Griffith’s film Birth of a Nation, which was released in 1915.

Air pollution is the most prominent and dangerous form of pollution. It occurs dues to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities releases a huge amount of chemical substances in the air every day; as a result, these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning. This releases sulphur dioxide into the air making it toxic. The effects of air pollution are evident too. Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain which in turn have increased temperatures, erratic rains and droughts worldwide making it tough for animals to survive. We breathe in every polluted particle from the air, the result is an increase in asthma and cancer in the lungs. Another effect of air pollution is ozone layer depletion. Ozone layer is the thin shield high up in the sky that prevents ultra violet rays from reaching the Earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs) which play a key role, were released into the atmosphere which contributed to the destruction of ozone layer. Water pollution has taken toll of all the surviving species of the earth. Almost 60% of the species live in water bodies. It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species. If you suspect that nearby water sources have been contaminated by a corporation then it might be a good idea to hire an expert to see you options. Moreover, spraying insecticides, pesticides like DDT on plants also pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Eutrophication is another big source; it occurs due to daily activities like washing clothes or utensils near lakes, ponds or rivers; this forces detergents to go into water which blocks sunlight from penetrating, thus reducing oxygen and making it inhabitable. Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependents on these. Waterborne disease like cholera, diarrhea have also increased in all places. Another type of pollution common in the countryside is soil pollution. Soil pollution occurs due to the incorporation of unwanted chemicals in the soil due to human activities. Insecticides and pesticides absorb the nitrogen compounds in the soil making it unfit for plants to derive nutrition. Release of industrial waste, mining and deforestation also damages the soil.7.
