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:
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 3S 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 car-dependent 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.

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:
We first learn about loving and caring relationships from our families. Family is  defined as   a domestic group of people with some degree of kinship - whether through blood, marriage, or adoption. Ideally, each child is nurtured, respected, and grows up to care for others and develop strong and healthy relationships. This does not mean that it is always easy to make and keep friends; it just means that we share the goal of having strong relationships.
"Family" includes your siblings and parents, as well as relatives who you may not interact with every day, such as your cousins, aunts, uncles, grandparents, and stepparents.
These are probably the people you are closest to and with whom you spend the most time.  Having healthy relationships with your family members is both important and difficult.
Families in the 21st century come in all shapes and sizes: traditional, single parent, blended  (more than one family together in the same house], and gay and lesbian parents -just to name a few. No matter the "type" of family you have, there are going to be highs and lows - good times and bad. Many times, however, families become blocked in  their relationships by  hurt, anger, mistrust, and confusion. These are natural and normal, and few families do not have at  least  a  few experiences with them. The worst time for most families, is during a divorce. By making a few  simple changes in the way we look at the world and deal with other people, it is possible to create happier, more stable relationships. Families need to be units of mutual caring and support; they can   be sources of lifelong strength for all individuals.

 Ideally, each child is nurtured, respected, and grows up to     ?

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:
By mid-century, there will likely be 9 billion people on the planet, consuming ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence advance? Will global warming trigger catastrophic changes, or will we be able to engineer our way out of the climate change crisis?
Making predictions is, by nature, a dicey business, but to celebrate the 40th anniversary of Smithsonian magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is our latest special series, Life in 20 50. Demographic changes in world population and population growth will certainly be dramatic. Rockefeller University mathematical biologist Joel Cohen says it's likely that by 2050 the majority of the people in the world will live in urban areas, and will have a significantly higher average age than people today. Cities theorist Richard Florida thinks urbanization trends will reinvent the education system of the United States, making our economy less real estate driven and erasing the divisions between home and work.
Large migrations from developing countries like Indonesia, Malaysia, Bangladesh, Mexico, and countries in the Middle East could disrupt western governments and harm the unity of France, Germany, Spain, the Netherlands, Poland, and the United Kingdom under the umbrella of the European Union.
And rapidly advancing technology will continue ever more rapidly. According to Bill Mitchell, the late director of MIT's Smart Cities research group, cities of the future won't look like "some sort of science -fiction fantasy" or "Star Trek" but it's likely that "discreet, unobtrusive" technological advances and information overlays, i.e. virtual reality and augmented reality, will change how we live in significant ways. Self-driving cars will make the roads safer, driving more efficient, and provide faster transports. A larger version of driverless cars-driverless trucks-may make long haul drivers obsolete.
Meanwhile, the Internet will continue to radically transform media, destroying the traditional model of what a news organization is, says author and former New York Times Public Editor, Daniel Okrent, who believes the most common kinds of news organizations in the future will be "individuals and small alliances of individuals” reporting and publishing on niche topics.

There are many mistakes that people make when writing their resume (CV) or completing a job application. Here are some of the most common and most serious.
The biggest problem is perhaps listing the duties for which you were responsible in a past position: all this tells your potential employers is what you were supposed to do. They do not necessarily know the specific skills you used in executing them, nor do they know what results you achieved - both of which are essential. In short, they won’t know if you were the best, the worst or just average in your position.
The more concrete information you can include, the better. As far as possible, provide measurements of what you accomplished. If any innovations you introduced saved the organization money, how much did they save? If you found a way of increasing productivity, by what percentage did you increase it?
Writing what you are trying to achieve in life - your objective - is a waste of space. It tells the employer what you are interested in. Do you really think that employers care what you want? No, they are interested in what they want! Instead, use that space for a career summary. A good one is brief - three to four sentences long. A good one will make the person reviewing your application want to read further.
Many resumes list ‘hard' job-specific skills, almost to the exclusion of transferable, or ‘soft’, skills. However, your ability to negotiate effectively, for example, can be just as important as your technical skills.
All information you give should be relevant, so carefully consider the job for which you are applying. If you are applying for a job that is somewhat different than your current job, it is up to you to draw a connection for the resume reviewer, so that they will understand how your skills will fit in their organization. The person who reviews your paperwork will not be a mind reader.
If you are modest about the skills you can offer, or the results you have achieved, a resume reader may take what you write literally, and be left with a low opinion of your ability: you need to say exactly how good you are. On the other hand, of course, never stretch the truth or lie.

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. 
      The Trump campaign ran on bringing jobs back to American shores, although mechanization has been the biggest reason for manufacturing jobs’ disappearance. Similar losses have led to populist movements in several other countries. But instead of a pro-job growth future, economists across the board predict further losses as AI, robotics, and other technologies continue to be ushered in. What is up for debate is how quickly this is likely to occur.
      Now, an expert at the Wharton School of Business at the University of Pennsylvania is ringing the alarm bells. According to Art Bilger, venture capitalist and board member at the business school, all the developed nations on earth will see job loss rates of up to 47% within the next 25 years, according to a recent Oxford study. “No government is prepared,” The Economist reports. These include blue and white collar jobs. So far, the loss has been restricted to the blue collar variety, particularly in manufacturing.
       To combat “structural unemployment” and the terrible blow, it is bound to deal the American people, Bilger has formed a nonprofit called Working Nation, whose mission it is to warn the public and to help make plans to safeguard them from this worrisome trend. Not only is the entire concept of employment about to change in a dramatic fashion, the trend is irreversible. The venture capitalist called on corporations, academia, government, and nonprofits to cooperate in modernizing our workforce.
       To be clear, mechanization has always cost us jobs. The mechanical loom, for instance, put weavers out of business. But it also created jobs. Mechanics had to keep the machines going, machinists had to make parts for them, and workers had to attend to them, and so on. A lot of times those in one profession could pivot to another. At the beginning of the 20th century, for instance, automobiles were putting blacksmiths out of business. Who needed horseshoes anymore? But they soon became mechanics. And who was better suited?
         Not so with this new trend. Unemployment today is significant in most developed nations and it’s only going to get worse. By 2034, just a few decades, mid-level jobs will be by and large obsolete. So far the benefits have only gone to the ultra-wealthy, the top 1%. This coming technological revolution is set to wipe out what looks to be the entire middle class. Not only will computers be able to perform tasks more cheaply than people, they’ll be more efficient too.
       Accountants, doctors, lawyers, teachers, bureaucrats, and financial analysts beware: your jobs are not safe. According to The Economist, computers will be able to analyze and compare reams of data to make financial decisions or medical ones. There will be less of a chance of fraud or misdiagnosis, and the process will be more efficient. Not only are these folks in trouble, such a trend is likely to freeze salaries for those who remain employed, while income gaps only increase in size. You can imagine what this will do to politics and social stability.

Though Edmund Halley was most famous because of his achievements as an astronomer, he was a scientist of diverse interests and great skill. In addition to studying the skies, Halley was also deeply interested exploring the unknown depths of the oceans. One of his lesser-known accomplishments that was quite remarkable was his design for a diving bell that facilitated exploration of the watery depths.
The diving bell that Halley designed had a major advantage over the diving bells that were in use prior to his. Earlier diving bells could only make use of the air contained within the bell itself, so divers had to surface when the air inside the bell ran low.
Halley's bell was an improvement in that its design allowed for an additional supply of fresh air that enabled a crew of divers to remain underwater for several hours.
The diving contraption that Halley designed was in the shape of a bell that measured three feet across the top and five feet across the bottom and could hold several divers comfortably; it was open at the bottom so that divers could swim in and out at will. The bell was built of wood, which was first heavily tarred to make it water repellent and was then covered with a half-ton sheet of lead to make the bell heavy enough to sink in water. The bell shape held air inside for the divers to breathe as the bell sank to the bottom.
The air inside the bell was not the only source of air for the divers to breathe, and it was this improvement that made Halley's bell superior to its predecessors. In addition to the air already in the bell, air was also supplied to the divers from a lead barrel that was lowered to the ocean floor close to the bell itself. Air flowed through a leather pipe from the lead barrel on the ocean floor to the bell. The diver could breath the air from a position inside the bell, or he could move around outside the bell wearing a diving suit that consisted of a lead bell-shaped helmet with a glass viewing window and a leather body suit, with a leather pipe carrying fresh air from the diving bell to the helmet.

Amelia Earhart was born in Kansas in 1897. Thirty one years later, she received a phone call that would change her life. She was invited to become the first woman passenger to cross the Atlantic Ocean in a plane. The flight took more than 20 hours – about three times longer than it routinely takes today to cross the Atlantic by plane. Earhart was twelve years old before she ever saw an airplane, and she didn’t take her first flight until 1920. But she was so thrilled by her first experience in a plane that she quickly began to take flying lessons. She wrote, “As soon as I left the ground, I knew I myself had to fly.”
After that flight Earhart became a media sensation. She was given a ticker tape parade down Broadway in New York and even president Coolidge called to congratulate her. Because her record – breaking career and physical appearance were similar to pioneering pilot and American hero Charles Lindbergh, she earned the nickname “Lady Lindy.” She wrote a book about her flight across the Atlantic, called 20 Hrs, 40 Min.
Earhart continued to break records, and also polised her skills as a speaker and writer, always advocating women’s achievements, especially in aviation. Her next goal was to achieve a transatlantic crossing alone. In 1927 Charles Lindbergh became the first person to make a solo nonstop flight across the Atlantic. Five years later, Earhart became the first woman to repeat that feat. Her popularity grew even more and she was the undisputed queen of the air. She then wanted to fly around the world, and in June 1973 she left Miami with Fred Noonan as her navigator. No one knows why she left behind important communication and navigation instruments. Perhaps it was to make room for additional fuel for the long flight. The pair made it to New Guinea in 21 days and then left for Howland Island, a tiny island in the middle of the Pacific Ocean. The last communication from Earhart and Noonan was on July 2, 1937 with a nearby Coast Guard ship. The United States Navy conducted a massive search for more than two week but no trace of the plane or its passengers was ever found. Many people believe they got lost simply ran out of fuel and died.

People in the UK enjoy fewer years of good health before they die than the citizens of most comparable European countries as well as Australia and Canada, a major report shows. While life expectancy has improved by 4.2 years in the UK over the two decades, other countries have improved faster. In 2010, Spain topped the league. Its people could expect 70.9 years of healthy life - before disease and disability began to take a toll. Second came Italy, with 70.2 years and third was Australia, on 70.1 years. In the UK, we can expect 68.6 healthy years of life.
Hunt said the UK was a long way behind its global counterparts and called for action by local health commissioners to tackle the five big killers - cancer, heart disease, stroke, respiratory and liver diseases. Drinking and drug use have been the main issues behind the worsening of the UK's ranking in early deaths among adults aged 20-54. In 2010, drugs were the sixth leading cause of death in this age group and alcohol was 18th - up from 32nd and 43rd place respectively 20 years earlier.
Hunt will on Tuesday announce a strategy to tackle cardiovascular disease, which he says could save 30,000 lives a year. "Despite real progress in cutting deaths, we remain a poor relative to our global cousins on many measures of health, something I want to change," he said. "For too long we have been lagging behind and I want the reformed health system to take up this challenge and turn this shocking underperformance around.” However, the problem is only in part to do with hospital care - much of it is about the way we live. Our diet, our drinking and continuing smoking habits all play a part, which assumes its responsibilities on 1 April.

The word “cardiovascular” in paragraph 2 could be best replaced by     .

Paul Watson is an environmental activist. He is a man who believes that he must do something, not just talk about doing something. Paul believes in protecting endangered animals, and he protects them in controversial ways. Some people think that Watson is a hero and admire him very much. Other people think that he is a criminal.
On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd. Watson and the people who work on the Sea Shepherd were hunting on the Atlantic Ocean near Portugal. However, they had a strange prey; instead of hunting for animals, their prey was a ship, the Sierra. The Sea Shepherd found the Sierra, ran into it and sank it. As a result, the Sierra never returned to the sea. The Sea Shepherd, on the other hand, returned to its home in Canada. Paul Watson and his workers thought that they had been successful.
The Sierra had been a whaling ship, which had operated illegally. The captain and crew of the Sierra did not obey any of the international laws that restrict whaling. Instead, they killed as many whales as they could, quickly cut off the meat, and froze it. Later, they sold the whale meat in countries where it is eaten.
Paul Watson tried to persuade the international whaling commission to stop the Sierra. However, the commission did very little, and Paul became impatient. He decided to stop the Sierra and other whaling ships in any way that he could. He offered to pay $25,000 to anyone who sank any illegal whaling ship, and he sank the Sierra. He acted because he believes that the whales must be protected. Still, he acted without the approval of the government; therefore, his actions were controversial.
Paul Watson is not the only environmental activist. Other men and women are also fighting to protect the Earth. Like Watson, they do not always have the approval of their governments, and like Watson, they have become impatient. Yet, because of their concern for the environment, they will act to protect it.

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

A leading question among anthropologists is: what exactly led to the development of human cities? Basically, modern humans have existed on earth for over 100,000 years. Yet it is only in the last 8,000 years that they have begun to gather in significant numbers and form cities. Prior to that period, humans existed in small family or tribal groups, generally consisting of fewer than 100 individuals. What, then, led humans to make the dramatic shift from living in small groups to living in large, organized cities? It seems that the development of cities required a particular set of circumstances.
First, it required a minimum population density. For much of their early history, humans existed only in small numbers. This is due to the fact that early humans relied on hunting and gathering wild foods for their survival. Even the most fertile land would only support a relatively small number of predators, so it was not until humans began to practice agriculture that they were able to gather in large enough numbers to form cities.
Furthermore, the development of a city could only be possible if a large number of people shared a common language, culture and religion. Without such unifying factors, a cooperative, peaceful existence among large numbers of people would have been impossible.
Finally, it seems that early humans needed to be faced with a large problem, which one small group of individuals could not solve on its own. Only when large-scale cooperation was needed to overcome a problem would humans come together to form cities.

Which of the following enabled people to live together in peace?

There are many different metaphors used to describe culture. My favorite one is the iceberg. I think, it demonstrates so vividly what can happen to us if we believe only in the visible and ignore or underestimate the invisible part. The hidden part of our culture is that part which we know instinctively because we absorbed it from childhood on. It's handed down to us from generation to generation. We could also say, it's the "thinking" and "feeling" part of culture: habits, assumptions, attitudes, desires, values, tastes, etc.
Now, if we are in a new culture, our customary evaluations and interpretations are likely not to be on target because we see everything through our own cultural glasses. Imagine yourself in a new city trying to get around with a map from your own hometown. It wouldn't take long for you to get lost and completely frustrated! When we experience an encounter in the new culture that puzzles us, the most common reaction is to judge it through our own cultural glasses. 
I want to propose an alternate approach to our initial gut reaction. Instead of immediately and instinctively judging a situation through our own glasses, we might first just pause and notice what is happening and then realize that this is a cultural learning situation. Remember the iceberg metaphor! The new culture becomes your mirror that shows you a hidden part of your own culture. What an opportunity for personal growth and new insight! You can compare two different approaches, that of the new culture and of your own culture. This gives you a choice. Now you can decide what fits best for you or even take the best from both sides.

Human memory, formerly believed to be rather inefficient, is really more sophisticated than that of a computer. Researchers approaching the problem from a variety of points of view have all concluded that there is a great deal more stored in our minds than has been generally supposed. Dr. Wilder Penfield, a Canadian neurosurgeon, proved that by stimulating their brains electrically, he could elicit the total recall of specific events in his subjects’ lives. Even dreams and other minor events supposedly forgotten for many years suddenly emerged in detail.
The memory trace is the term for whatever is the internal representation of the specific information about the event stored in the memory. Assumed to have been made by structural changes in the brain, the memory trace is not subject to direct observation but is rather a theoretical construct that we use to speculate about how information presented at a particular time can cause performance at a later time. Most theories include the strength of the memory trace as a variable in the degree of learning, retention, and retrieval possible for a memory. One theory is that the fantastic capacity for storage in the brain is the result of an almost unlimited combination of interconnections between brain cells, stimulated by patterns of activity. Repeated references to the same information support recall. Or, to say that another way, improved performance is the result of strengthening the chemical bonds in the memory.

The word “elicit” is closest in meaning to...........................

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:
Urban populations interact with their environment. Urban people change their  environment through their consumption of Food, energy, water, and land. And in turn, the polluted urban environment affects the health and quality of life of the urban population. People who live in urban areas have very different consumption patterns than residents in rural areas. For example, urban populations consume much more food, energy, and durable goods than rural populations. In China during the 1970s, the urban populations consumed twice as much pork as the rural populations who were raising the pigs. With economic development,  the difference  in  consumption declined as the rural populations ate better diets. But even a decade later, urban populations had 60 percent more pork in their diets than rural populations. The increasing consumption of meat is a sign of growing affluence in Beijing; in India where  many  urban  residents are vegetarians, greater prosperity is seen in higher consumption of milk.
Urban populations not only consume more food, but they also consume more durable goods, In the early 1990s, Chinese households in urban areas were two times more likely to have a   TV, eight times more likely to have a washing machine, and 25 times more likely to have a refrigerator than rural households. This increased consumption is a function of urban labor markets, wages, and household structure.
Urban consumption of energy helps create heat islands that can change local weather patterns and weather downwind from the heat islands. The heat  island  phenomenon is created because cities radiate heat back into the atmosphere at rate 15 percent to 30 percent less than rural areas. The combination of the increased energy consumption and difference in albedo (radiation) means that cities are warmer than rural areas (0.6 to 1.3 C), And these heat islands become traps for  atmospheric pollutants. Cloudiness and fog occur with greater frequency. Precipitation is 5 percent to 10 percent higher in cities; thunderstorms and hailstorms are much  more frequent, but snow days in cities are less common.
Urbanization also affects the broader regional environments. Regions  downwind  from  large industrial complexes also see increases in the amount of precipitation, air pollution, and the number of days with thunderstorms. Urban areas affect not only the weather patterns, but also the runoff patterns for water. Urban areas generally generate more rain, but they reduce the infiltration of water and lower the water tables. This means that runoff occurs more rapidly with greater peak flows. Flood volumes increase, as do floods and water pollution downstream.
Many of the effects of urban areas on the environment are not necessarily linear. Bigger  urban areas do not always create more environmental problems. And small urban areas can cause large problems. Much of what determines the extent of the environmental impacts is how the urban populations behave - their consumption and living patterns - not just how large they are.

Which of the following is TRUE about the food consumption of Chinese urban inhabitants?
