Read the following passage and choose the best answer (A, B, C, D):
We live in a world of tired, sleep deprived people. In his book Counting Sheep, Paul Martin - a behavioral biologist - describes a society which is just too busy to sleep and which does not give sleeping the importance it deserves. Modern society has invented reasons not to sleep. We are now a 24/7 society where shops and services must be available all hours. We spend longer hours at work than we used to, and more time getting to work. Mobile phones and email allow us to stay in touch round the clock and late-night TV and the Internet tempt us away from our beds. When we need more time for work or pleasure, the easy solution is to sleep less. The average adult sleeps only 6.2 hours a night during the week, whereas research shows that most people need eight or even eight and a half hours’ sleep to feel at their best. Nowadays, many people have got used to sleeping less than they need and they live in an almost permanent state of “sleep debt”. Until the invention of the electric light in 1879 our daily cycle of sleep used to depend on the hours of daylight. People would get up with the sun and go to bed at nightfall. But nowadays our hours of sleep are mainly determined by our working hours (or our social life) and most people are woken up artificially by an alarm clock. During the day caffeine, the world’s most popular drug, helps to keep us awake. 75% of the world’s population habitually consume caffeine, which up to a point masks the symptoms of sleep deprivation. What does a chronic lack of sleep do to us? As well as making us irritable and unhappy as humans, it also reduces our motivation and ability to work. This has serious implications for society in general. Doctors, for example, are often chronically sleep deprived, especially when they are on “night call”, and may get less than three hours’ sleep. Lack of sleep can seriously impair their mood, judgment, and ability to take decisions. Tired engineers, in the early hours of the morning, made a series of mistakes with catastrophic results. On our roads and motorways lack of sleep kills thousands of people every year. Tests show that a tired driver can be just as dangerous as a drunken driver. However, driving when drunk is against the law but driving when exhausted isn’t. As Paul Martin says, it is very ironic that we admire people who function on very little sleep instead of criticizing them for being irresponsible. Our world would be a much safer, happier place if everyone, whatever their job, slept eight hours a night

Read the following passage and choose the best answer (A, B, C, D):
Ask about “the population problem” to people of a certain age, and the first and perhaps only thing that comes to mind is the “population bomb” or “population explosion.” And they would be right - for their time. In the second half of the 20th century, rapid population growth - especially but not exclusively in the developing countries - created unprecedented increases in the number of people on the earth. And this growth was accompanied by crowding, malnutrition, disease, and poverty. Indeed, for many Americans, the coming “population explosion” was, along with the Cold War, the most unsettling fact about our world. But “population problems” have been part of American discourse for over 100 years. In the 1930s and 1940s, for instance, many observers feared that depopulation due to plummeting birth rates would cause chronic economic depression as the numbers of U.S. consumers and workers declined. In the 1920s, the U.S. “population problem” was rapid urbanization, reflected in a 1920 census count showing that for the first time more than onehalf the population lived in urban areas. Rural incumbents in the House of Representatives, fearing they would be voted out of office by their new urban constituents, succeeded in blocking reapportionment of the House’s seats on the basis of the census counts as mandated by the U.S. Constitution. The century’s first “population problem” was mass xenophobia about immigration. Beginning in 1880, wave after wave of European immigrants was creating congestion and social change at an unprecedented rate. In response to widespread anxiety and anger, Congress in 1924 passed the country’s most restrictive immigration legislation ever. Each problem was based in hard numbers. Each generated private emotions and public fears. Each suffered exaggeration and manipulation. And each commanded the attention of opinion leaders and elected officials.

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.
3. What can be inferred from the passage? -
Most Americans still get married at some point in their lives, but even that group is shrinking. Among current generations of adult American - starting with those bom in 1920s - more than 90 percent have married or will marry at some point in their lives. However, based on recent patterns of marriage and mortality, demographers calculate that a growing share of the younger generations are postponing marriage for so long that an unprecedented number will never marry at all.
More Americans are living together outside of marriage. Divorced and widowed people are waiting longer to remarry. An increasing number of single women are raising children. Put these trends together with our increasing life expectancy, and the result is inevitable. Americans are spending a record low proportion of their adult lives married.
Married rates for unmarried men and women have dropped from their post-195Os high to record lows. Part of this fall is due to the change in the age at which people first marry. The median age at first marriage is the age by which half the men or women who will ever marry have done so. It fell almost continuously from the time it was first measured, in 1890, at 22.0 years for women and 26.1 for men, to a low of 20.3 for women and 22.6 for men between 1947 and 1962. Since then, it has risen at a rapid pace, to a record high for 23.8 for women and 26.2 for men in 1994.
The length of time between marriages is also increasing, and more divorced people are choosing not to remarry. In 1990, divorced men had waited an average of 3.8 years before remarrying, and divorced women had waited an average of 3.5 years, an increase of more than one year over the average interval in 1970.
Data on cohabitation and unmarried childbearing suggest that marriage is becoming less relevant to Americans. 2.8 million of the nation's households are unmarried couples, and one-third of them are caring for children, according to the Census Bureau

Read the following passage and choose the best answer (A, B, C, D):
During the past half-century, our species has embarked on a remarkable social experiment. For the first time in human history, great numbers of people – at all ages, in all places, of every political persuasion – have begun settling down as singletons. Until the second half of the last century, most of us married young and parted only at death. If death came early, we remarried quickly; if late, we moved in with family, or they with us. Now we marry later. We divorce, and stay single for years or decades. The rise of living alone has produced significant social benefits, too. Young and middle-aged solos have helped to revitalise cities, because they are more likely to spend money, socialise and participate in public life. Contemporary solo dwellers in the US are primarily women: about 18 million, compared with 14 million men. The majority, more than 16 million, are middle-aged adults between the ages of 35 and 64. The elderly account for about 11 million of the total. Young adults between 18 and 34 number increased more than 5 million, compared with 500,000 in 1950, making them the fastest-growing segment of the solo-dwelling population. Despite fears that living alone may be environmentally unsustainable, solos tend to live in apartments rather than in big houses, and in relatively green cities rather than in cardependent suburbs. There’s good reason to believe that people who live alone in cities consume less energy than if they coupled up and decamped to pursue a single-family home.

Have you ever been cycling? This spring my elder brother and I left the busy city and spent a long weekend cycling in the countryside. Our average speed was only around 14 kph, but that didn’t matter. We hadn’t come to break any speed records, or to get fit and healthy. All we wanted was some fresh air and a break from schoolwork. My bike only once went more than 30 kph, and that was when I raced my brother down the only hill on our route. We really enjoyed cycling along flat, traffic-free country paths. There was plenty of spring sunshine, but it was quite cold, especially in the morning. We didn’t mind, though - and we soon warmed up as we rode along. Our only problem was when my brakes started making a terrible noise. But I didn’t mind as it gave us an excuse to visit a cafe while a helpful bike mechanic had a look at it. That was one of the best things about our route: every few kilometres there was a village where we could find everything we needed. All the local people were really friendly, too. However, most places we stopped at served chips with the meals, which soon got fairly boring. One night we were woken at 4 a.m. by a group of rugby fans singing loudly in the hotel corridor. We were tired and bad-tempered when we set off the next morning and very nearly got lost, but soon felt more cheerful when the sun came out. That’s what I like about cycling - it’s simple and it’s fun. If you’re looking for a short break that’s active and cheap, then cycling is a great choice!

Read the following passage and choose the best answer (A, B, C, D):
Advertising helps people recognize a particular brand, persuades them to try it, and tries to keep them loyal to it. Brand loyalty is perhaps the most important goal of consumer advertising. Whether they produce cars, canned foods or cosmetics, manufacturers want their customers to make repeated purchases. [2] The quality of the product will encourage this, of course, but so, too, will affect advertising. Advertising relies on the techniques of market research to identify potential users of a product. [3] Are they homemakers or professional people? Are they young or old? Are they city dwellers or country dwellers? Such questions have a bearing on where and when ads should be placed. By studying readership breakdowns for newspapers and magazines as well as television ratings and other statistics, an advertising agency can decide on the best way of reaching potential buyers. Detailed research and marketing expertise are essential today when advertising budgets can run into thousands of millions of dollars. [4] Advertising is a fast-paced, high-pressure industry. There is a constant need for creative ideas that will establish a personality for a product in the public’s mind. Current developments in advertising increase the need for talented workers. In the past, the majority of advertising was aimed at the traditional white family - breadwinner father, non-working mother, and two children. Research now reveals that only about 6 percent of American households fit this stereotype. Instead, society is fragmented into many groups, with working mothers, single people and older people on the rise. To be most successful, advertising must identify a particular segment and aim its message toward that group. Advertising is also making use of new technologies. Computer graphics are used to grab the attention of consumers and to help them see products in a new light. The use of computer graphics in a commercial for canned goods, for instance, gave a new image to the tin can

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
In the United States, it is important to be on time, or punctual, for an appointment, a class, a meeting, etc... This may not be true in some other countries, however. An American professor discovered this difference while teaching a class in a Brazilian university. The two-hour class was scheduled to begin at 10 a.m, and end at 12 a.m. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after 11 a.m. Although all of the students greeted the professor as they arrived, few apologised for their lateness. Were these students being rude? He decided to study the students’ behavior.
In American university, students are expected to arrive at the appointed hour. On the other hand, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but they also end at the scheduled time. In the Brazilian class, only a few students left the class at noon, many remained past 12:30 to discuss the class and ask more questions. While arriving late may not be important in Brazil, neither is staying late.
The explanation for these differences is complicated. People from Brazilian and North American cultures have different feelings about lateness. In Brazil, the students believe that a person who usually arrives late is probably more successful than a person who is always on time. In fact, Brazilians expect a person with status or prestige to arrive late, while in the United States, lateness is usually considered to be disrespectful and unacceptable. Consequently, if a Brazilian is late for an appointment with a North America, the American may misinterpret the reason for the lateness and become angry.
As a result for his study, the professor learned that the Brazilian students were not being disrespectful to him. Instead, they were simply behaving the appropriate way for a Brazilian student in Brazil. Eventually, the professor was able to adapt his own behavior to feel comfortable in the new culture.In general, what did the Brazilian students think about people who are late?

Read the following passage and choose the best answer (A, B, C, D):
Most languages have several levels of vocabulary that may be used by the same speakers. In English, at least three have been identified and described. Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both colloquial usage and slang are more common in speech than writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population. Finally, it is worth noting that the terms "standard", "colloquial", and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use three types of expressions.

Coal, oil and gas get more than $370bn a year in support, compared with $100bn for renewables, the International Institute for Sustainable Development (IISD) report found. Just 10-30% of the fossil fuel subsidies would pay for a global transition to clean energy, the IISD said. Ending fossil fuel subsidies has long been seen as vital to tackling the climate emergency, with the G20 nations pledging in 2009 to phase them out, but progress has been limited. The new analysis shows how redirecting some of the fossil fuel subsidies could decisively tip the balance in favour of green energy, making it the cheapest electricity available and instigating a rapid global rollout. The transition from polluting fossil fuels to clean energy is already under way. Annual investment in renewables has been greater than that in fossil fuel electricity generation since 2008 and new renewable capacity has exceeded fossil fuel power each year since 2014. But progress is slow compared with the urgency required, said Bridle. “There is no question that renewables can power the energy system,” he said. “The question now is can we transit quickly enough away from fuels like coal, and subsidy reform is a very obvious step towards that. Reform of fossil fuel subsidies could have a significant impact on global heating. An earlier IISD study of 20 countries with large fossil fuel subsidies found that a 30% swap to renewables would lead to emissions reductions of between 11% and 18%. Most experts define fossil fuel subsidies as financial or tax support for those buying fuel or the companies producing it. The IMF also includes the cost of the damage fossil fuel burning causes to climate and health, leading to an estimate of $5.2tn of fossil fuel subsidies in 2017, or $10m a minute. Ending the subsidies would cut global emissions by about a quarter, the IMF estimates, and halve the number of early deaths from fossil fuel air pollution. Bridle said funding fossil fuel subsidies was “madness”, but said ending them could cause short-term price rises and political difficulties, as the benefits of lower costs in the future and reduced air pollution are less obvious. “There are political problems but it is worth persevering because the prize is so big,” he said. “You have to bring people along with you.” Gençsü said governments must ensure that the most vulnerable people were not adversely affected by changes.

Read the following passage and choose the best answer (A, B, C, D):
How busy is too busy? For some it means having to miss the occasional long lunch; for others, it means missing lunch altogether. For a few, it is not being able to take a “sickie” once a month. Then there is a group of people for whom working every evening and weekend is normal, and frantic is the tempo of their lives. For most senior executives, workloads swing between extremely busy and frenzied. The vice-president of the management consultancy AT Kearney and its head of telecommunications for the Asia-Pacific region, Neil Plumridge, says his work weeks vary from a “manageable” 45 hours to 80 hours, but average 60 hours. Three warning signs alert Plumridge about his workload: sleep, scheduling and family. He knows he has too much on when he gets less than six hours of sleep for three consecutive nights; when he is constantly having to reschedule appointments; “and the third one is on the family side”, says Plumridge, the father of a three-year-old daughter, and expecting a second child in October. “If I happen to miss a birthday or anniversary, I know things are out of control.” Being “too busy” is highly subjective. But for any individual, the perception of being too busy over a prolonged period can start showing up as stress: disturbed sleep, and declining mental and physical health. National workers’ compensation figures show stress causes the most lost time of any workplace injury. Employees suffering stress are off work an average of 16.6 weeks. The effects of stress are also expensive. Comcare, the Federal Government insurer, reports that in 2003-04, claims for psychological injury accounted for 7% of claims but almost 27% of claim costs. Experts say the key to dealing with stress is not to focus on relief – a game of golf or a massage – but to reassess workloads. Neil Plumridge says he makes it a priority to work out what has to change; that might mean allocating extra resources to a job, allowing more time or changing expectations. The decision may take several days. He also relies on the advice of colleagues, saying his peers coach each other with business problems. “Just a fresh pair of eyes over an issue can help,” he says. Executive stress is not confined to big organizations. Vanessa Stoykov has been running her own advertising and public relations business for seven years, specializing in work for financial and professional services firms. Evolution Media has grown so fast that it debuted on the BRW Fast 100 list of fastest-growing small enterprises last year – just after Stoykov had her first child. Stoykov thrives on the mental stimulation of running her own business. “Like everyone, I have the occasional day when I think my head’s going to blow off,” she says. Because of the growth phase the business is in, Stoykov has to concentrate on short-term stress relief – weekends in the mountains, the occasional “mental health” day – rather than delegating more work. She says: “We’re hiring more people, but you need to train them, teach them about the culture and the clients, so it’s actually more work rather than less.”

Perfectly smart adults feel intimidated by numbers and aren’t ashamed to say, “I hate math.” The new book “Math Art” could help change that by making the dreaded topic relevant and accessible to naturalists, artsy types, the philosophically inclined, and committed calculators alike. It illuminates an old lesson your math teachers probably tried to convey when you were a kid: Math dominates our lives even while we try with all our might to ignore it. In Math Art, released in April, science writer Ornes examines creative works inspired by math. It’s an aesthetically pleasing book with a delightfully tactile cover and satisfyingly thick and glossy pages that make it as fun to flip through as a fashion magazine. Chapters are dedicated to different concepts like pi, the golden ratio, equations in nature, and hyperbolic geometry. All of which may sound scary to the uninitiated but gain appeal when illustrated through sculpture, crochet, and painting. As Ornes explains in the introduction, math art isn’t new. Since ancient times, humans have visualized math in creative works. He argues that what is new is the mutual recognition that mathematicians and artists now show each other, increasingly gathering together at events dedicated to the intersection of aesthetics and numbers. “This is art by way of math and math by way of art, beauty at the crossroads,” Ornes writes. His exploration begins with pi, the irrational mathematical constant 3.14159, plus some, ad infinitum. Pi, the ratio of the circumference of a circle to its diameter, represents mystery itself. Because the sequence never repeats, pi hints at the vastness of the universe. “It speaks to a world without bounds, since its digits go on forever,” Ornes explains. Pi is used for calculations in math and physics, and employed by math artist John Sims to make music, videos, drawings, paintings, quilts, clothing, and stories. Sims created and taught a math curriculum for students at the Ringling College of Art and Design in Sarasota, Florida, and has spent much of his career at the intersection of math and creativity. In Ornes’ book, he explains how he’s also used this fascination to connect with other people he might not otherwise meet, such as the Amish quilters who joined him to make pi quilts with each colored panel representing a number in the mathematical sequence.

Nowadays, dozens of interventions are known that extend the lifespan of various living organisms ranging from yeast to mammals. They include chemical compounds, genetic interventions, and diets. Some targets of these interventions have been discovered. However, there is still no clear understanding of the systemic molecular mechanisms leading to lifespan extension. A group of scientists from Skoltech, Moscow State University and Harvard University decided to fill this gap and identify crucial molecular processes associated with longevity. To do so, they looked at the effects of various lifespan-extending interventions on the activity of genes in a mouse, a commonly used model organism closely related to humans. “In our lab, we subjected mice of different sexes and ages to 8 longevity interventions and analyzed gene expression changes induced by these treatments. After aggregating our data with the datasets published by other groups, we obtained gene activity profiles of 17 interventions. Although in general the effects produced by individual treatments turned out to be rather specific, a certain group of genes changed its expression in a similar way in response to different lifespan-extending interventions,” says the first author of the study, Alexander Tyshkovskiy. The scientists then applied the discovered biomarkers to search for other interventions with the same effect on their activity and, therefore, high potential for lifespan extension "Currently, we are validating these hits by testing their effect on the mouse lifespan. We hope that our biomarkers will significantly facilitate the search for new longevity interventions and help improve the healthspan and lifespan in rodents and, in the long term, in humans," says Alexander.
