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:
Dear Editor,
I read with interest the article on American families. In general I agree with it, but there are some important things it left out. It didn't tell the reader much about the life of a househusband. It's not an easy life. I know, because I'm now a househusband myself. A househusband has to change many of his ideas and his ways.
First of all, he has to change the way he thinks about time. Before I was a househusband, I worked full-time for the New York Times. I was a reporter, and time was always important. We had to finish our article quickly and give them to the editor. Everyone was always in a hurry. This is the way, many other men work, too. Businessmen, lawyers, bankers, and doctors all have to work quickly.
At home it's different. The househusband cannot be in a hurry all the time. If you rush around, you will make everyone unhappy! The children will be unhappy because they don't understand. For them, time is not important. Your wife will be unhappy because the children are unhappy. You will be unhappy, too, because they are all unhappy. So you have to learn to slow down. That is the first and most important rule for a househusband.
There is something else the househusband must learn. You must learn to show how you feel about things. At work, men usually do not talk about feelings. If they do, people think they are strange. So, many men are not used to telling anyone about their feelings. They do not know how to talk about their anger, worries, or love. But children need to know how you feel. They need to know how much you love them. If you are angry, they need to know why. Your wife also needs to know about your feelings. If you do not say anything, your family may get the wrong idea. Then there may be serious problems.
People talk a lot about househusbands these days. Usually they talk about men doing the housework, the cooking, cleaning, and shopping. But in my opinion, these are the easiest things to learn. It was much harder for me to change the way I think and the way I act with my family. I think, other men will also find this harder, but, like me, will find it necessary if they want to have a happy family!

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:
Sometimes people add to what they say even when they don't talk. Gestures are the "silent language" of every culture. We point a finger or move another part of the body to show what we want to say. It is important to know the body language of every country or we may be misunderstood. In the United States, people greet each other with a handshake in a formal introduction. The handshake must be firm. If the handshake is weak, it is a sign of weakness or unfriendliness. Friends may place a hand on the other's arm or shoulder. Some people, usually women, greet a friend with a hug.
Space is important to Americans. When two people talk to each other, they usually stand about two and a half feet away and at an angle, so they are not facing each other directly. Americans get uncomfortable when a person stands too close. They will move back to have their space. If Americans touch another person by accident, they say, "Pardon me." or "Excuse me." Americans like to look the other person in the eyes when they are talking. If you don't do so, it means you are bored, hiding something, or are not interested. But when you are stare at someone, it is not polite. For Americans, thumbs-up means yes, very good, or well done. Thumbs down means the opposite. To call a waiter, raise one hand to head level or above. To show you want the check, make a movement with your hands as if you are signing a piece of paper. It is all right to point at things but not at people with the hand and index finger. Americans shake their index finger at children when they scold them and pat them on the head when they admire them. Learning a culture's body language is sometimes confusing. If you don't know what to do, the safest thing to do is to smile.The word “them” in paragraph 2 refers 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:
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.The word "circumstances" in paragraph 1 mostly means .

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.According to paragraph 3, the following are mentioned as examples of durable goods, EXCEPT .

The tradition of gift giving is a worldwide (1)_________ that is said to have been around since the beginning of human beings. Over time, different cultures have developed their own gift giving customs and traditions.
In France, the gift of wine for the hostess of a dinner party is not an appropriate gift as the hostess would prefer to choose the vintage for the night. In Sweden, a bottle of wine or flowers are an appropriate gift for the hostess. In Viet Nam, a gift of whisky is appropriate for the host, and some fruit or small gifts for the hostess, children or elders of the home. Besides, gifts should never be wrapped in black paper because this color is unlucky and associated with funerals in this country.

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:
More often than not, you can't just "order up a job" by responding to an online posting and have it delivered in one or two days as if you were buying whatever your heart desires on Amazon. Even as employers are hiring at a higher rate than they have in the last several years, it can often take months to work your way through the job search process. If you are a new graduate yet to receive a job offer, if you recently moved to a new locale with your spouse or partner or if you are unemployed for any other reason, you may find success in your job search by spending time volunteering at a nonprofit organization.
Both the nonprofit and for-profit worlds need people with many of the same talents. The best volunteer jobs for you to consider are ones where the experience you acquire will be applicable in the "for-pay" position you want to attain. It's often the case that once you display your passion for the organization and its mission, and have demonstrated your abilities, you'll earn strong consideration when a paying position opens up that can benefit from your talents. Even if you don't have a path to employment at the place you volunteer, by highlighting your volunteer experience on your resume, you can demonstrate that you haven't been wasting your time away staying at home watching the grass grow.
There are a few strategies you might adopt when considering at which organization you'll want to volunteer. You' ll probably want to make a priority of volunteering to do what you've already done, or want to do, in the for-profit sector. Alternatively, however, it might make sense to volunteer to do something where you can turn an area of professional weakness into a new strength. Remember, as well, that nonprofit organizations maintain strong relationships with their corporate sponsors, and you might look for a volunteer position that would enable you to be that nexus point between the two. And, especially if you are recently out of school, you should look for positions that let you learn about an occupation, a field of interest or an industry.
As you try to determine what you want to volunteer to do, and where you want to do it, make three lists: your marketable skills, the roles you seek and the kinds of charitable organizations you would want to support. For example, perhaps your skills cluster around accounting, marketing or event planning. Think about how these might come in handy for organizations that need financial help figuring out how to brand the organization to attract other volunteers or donors or run anything from charitable golf tournaments to gala dinners.Which of the following could best describe the author's attitude about volunteering when being unemployed?

Read the passage below and decide whether the statements are TRUE or FALSE?
In 1981, the Association of Zoos and Aquariums (AZA) created a Species Survival Plan (SSP) in order to help preserve specific endangered and threatened species through captive breeding. With over 450 SSP Plans, there are a number of endangered species that are covered by the AZA with plans to cover population management goals and recommendations for breeding for a diverse and healthy population, created by Taxon Advisory Groups. These programs are commonly created as a last resort effort. SSP Programs regularly participate in species recovery, veterinary care for wildlife disease outbreaks, and a number of other wildlife conservation efforts. The AZA's Species Survival Plan also has breeding and transfer programs, both within and outside of AZA - certified zoos and aquariums. Some animals that are part of SSP programs are giant pandas, lowland gorillas, and California condors.

These days it is easy for most of us to get a hold of the latest books or magazines. We can go to bookstores, order them through the Internet, or borrow them from the local libraries. Now imagine having to walk miles and miles through a hot sandy desert just to borrow a book. This is the reality for people living in the villages of the Carissa region of Kenya in East Africa.
In 1996, librarian Wycliffe Oluoch used to spend each day waiting for people to come to borrow some of the 24,000 books in his library in Carissa. The library had no shortage of books, but people weren’t coming to read them. It was too much effort to walk through the desert just to borrow books. Oluoch racked his brain for ways to entice people into the library. After a lot of thought, he hit upon a great idea. If people wouldn’t come to the library, then he would have to take the library to them. Oluoch strapped boxes of books onto the backs of camels, and created the Mobile Camel Library.
Starting with three camels in 1996, but more recently expanding the service to six camels, the Mobile Camel Library serves over one million people. Twice a month, the camel library can be seen carrying books all around the Carissa region. These hard-working animals need little water and can carry up to 500 pounds of books across the sands. A librarian, a library assistant, a herdsman, and a lookout all travel with the camels. The lookout helps protect the books from thieves.
The children of Carissa love the camel library and appreciate Oluoch’s effort. Eleven-year-old Mohamud Mohamed reads his library books carefully and always returns them on time. He knows the Carissa library punishes people for losing books, just like any other library. However, the punishment is very stiff compared to that of other libraries. If a village loses a book, the camel library stops visiting.aThe word “stiff” 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.
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.The word “downtime” in paragraph 3 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.
There are already many, many people who have passed the landmark age of 100. In fact, there are now so many healthy, elderly people that there's a new term for them: the wellderly. These are people over the age of 80 who have no diseases such as high blood pressure, heart disease or diabetes and have never taken medicines for these conditions.
There have been many scientific studies of communities where a healthy old age is typical. These include places like Calabria in southern Italy and the island of Okinawa in Japan.
The small village of Molochio in Calabria has about 2,000 inhabitants. And of these there are at least eight centenarians. When researchers ask people like this the secret of their long life, the answer is almost always to do with diet and is almost always the same: 'I eat a lot of fruit and vegetables.' 'A little bit, but of everything.’ ‘No smoking, no drinking.’
While in the past scientists have looked at things such as diet and lifestyle for an explanation of long life, these days they are investigating genetics. One such researcher is Eric Topol, who says, "There must be genes that explain why these individuals are protected from the aging process."
The new research into long life looks at groups of people who have a genetic connection. For example, one group of interest lives in Ecuador. In one area of the country there are a number of people with the same genetic condition. It's called Laron syndrome. The condition means that they don't grow to more than about one, but it also seems to give them protection against cancer and diabetes. As a result, they live longer than other people in their families. Meanwhile, on the Hawaiian island of Oahu, there's another group of long-lived men, Japanese-Americans. They have a similar gene to the Laron syndrome group.
Back in Calabria, scientists are trying to work out exactly how much of the longevity is due to genetics and how much to environment. By checking public records going back to the 19th century, researchers have reconstructed the family trees of 202 nonagenarians and centenarians. They concluded that there were genetic factors involved. 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.

Before the grass has thickened on the roadside verges and leaves have started growing on the trees is a perfect time to look around and see just how dirty Britain has become. The pavements are stained with chewing gum that has been spat out and the gutters are full of discarded fast food cartons. Years ago I remember travelling abroad and being saddened by the plastic bags, discarded bottles and soiled nappies at the edge of every road. Nowadays, Britain seems to look at least as bad. What has gone wrong?
The problem is that the rubbish created by our increasingly mobile lives lasts a lot longer than before. If it is not cleared up and properly thrown away, it stays in the undergrowth for years; a semi-permanent reminder of what a tatty little country we have now. Firstly, it is estimated that 10 billion plastic bags have been given to shoppers. These will take anything from 100 to 1,000 years to rot. However, it is not as if there is no solution to this. A few years ago, the Irish government introduced a tax on non-recyclable carrier bags and in three months reduced their use by 90%. When he was a minister, Michael Meacher attempted to introduce a similar arrangement in Britain. The plastics industry protested, of course. However, they need not have bothered; the idea was killed before it could draw breath, leaving supermarkets free to give away plastic bags.
What is clearly necessary right now is some sort of combined initiative, both individual and collective, before it is too late. The alternative is to continue sliding downhill until we have a country that looks like a vast municipal rubbish tip. We may well be at the tipping point. Yet we know that people respond to their environment. If things around them are clean and tidy, people behave cleanly and tidily. If they are surrounded by squalor, they behave squalidly. No much of Britain looks pretty squalid. What will it look like in five years?The word “alternative” in the last paragraph is closest in meaning to _.

It weighed about 10,000 tons, entered the atmosphere at a speed of 64,000 km/h and exploded over a city with a blast of 500 kilotons. But on 15 February 2013, we were lucky. The meteorite that showered pieces of rock over Chelyabinsk, Russia, was relatively small, at only about 17 metres wide. Although many people were injured by falling glass, the damage was nothing compared to what had happened in Siberia nearly one hundred years ago. Another relatively small object (approximately 50 metres in diameter) exploded in mid–air over a forest region, flattening about 80 million trees. If it had exploded over a city such as Moscow or London, millions of people would have been killed.
By a strange coincidence, the same day that the meteorite terrified the people of Chelyabinsk, another 50m–wide asteroid passed relatively close to Earth. Scientists were expecting that visit and know that the asteroid will return to fly close by us in 2046, but the Russian meteorite earlier in the day had been too small for anyone to spot.
Most scientists agree that comets and asteroids pose the biggest natural threat to human existence. It was probably a large asteroid or comet colliding with Earth which wiped out the dinosaurs about 65 million years ago. An enormous object, 10 to 16 km in diameter, struck the Yucatan region of Mexico with the force of 100 megatons. That is the equivalent of one Hiroshima bomb for every person alive on Earth today.
Many scientists, including the late Stephen Hawking, say that any comet or asteroid greater than 20 km in diameter that hits Earth will result in the complete destruction of complex life, including all animals and most plants. As we have seen, even a much smaller asteroid can cause great damage.
The Earth has been kept fairly safe for the last 65 million years by good fortune and the massive gravitational field of the planet Jupiter. Our cosmic guardian, with its stable circular orbit far from the sun, sweeps up and scatters away most of the dangerous comets and asteroids which might cross Earth’s orbit. After the Chelyabinsk meteorite, scientists are now monitoring potential hazards even more carefully but, as far as they know, there is no danger in the foreseeable future.According to the last paragraph, scientists say that .

The ocean bottom - a region nearly 2.5 times greater than the total land area of Earth - is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.
Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.
The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world.. The Glomar Challenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth.
The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world’s past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change - information that may be used to predict future climates.The word “they” refers ................

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:
Mark Zuckerberg was born in 1984, in New York, into a prosperous, professional family. He developed an interest in computers at an early age and when he was twelve, he created a messaging program which he named "Zucknet". His dentist father used it in his surgery so that his receptionist could inform him of the arrival of a patient without yelling across the room. Together with his friends, Mark spent much of his spare time as a boy designing and making computer games just for fun.
In 2002, Mark enrolled at Harvard University. By his second year at the institution, he had acquired a reputation on the campus as a developer of software. It was at that time he invented "Facemash" which compared pictures of female students and allowed users to vote on which one was the most attractive. The program became very popular on campus, but was later shut down by the university authorities who deemed it 'inappropriate'.
Based on the buzz of "Facemash", three of Mark's fellow students, Divya Narendra, and twins, Cameron and Tyler Winklevoss, asked him to work with them on an idea for a social networking site called "Harvard Connection". This site was designed to use information from Harvard's student networks to create a dating site for the university's elite. Mark was initially enthusiastic about the complex project but boredom soon set in
and he backed out of it to work on his own social networking site. He created a site that allowed users to produce their own profiles, upload photos, and communicate with other people beyond the confines of the university. He called the site "Facebook" and he operated from one small college room until June 2004 when he finally abandoned his studies to devote himself fully to Facebook and moved the company to California. By the end of 2004, Facebook had one million users and Mark was climbing high.Which of the following best serves as the title for the passage?

Dinosaurs were reptiles that lived during a period of earth’s history called the Mesozoic Era, which is also known as the Age of Reptiles. The first dinosaurs appeared more than 200 million years ago. For many millions of years, they dominated the land with their huge size and strength. Then about 65 million years ago, they died out rather suddenly, never to re-emerge. The word “dinosauras” comes from two Greek words meaning “terrible lizard”. Dinosaurs were not lizards, but their appearance could be truly terrifying. The biggest ones weighed more than ten times as much as a mature elephant and nearly equalled the size of most modern-day whales. The famous kinds of dinosaurs, including the brontosaur and tyrannosaurus rex, reached 80 to 90 feet in length. Not all dinosaurs were giant, however, some were actually not larger than a chicken. Scientists still do not know what caused dinosaurs to disappear. One theory involves a change of the earth’s climate. It is believed that temperatures dropped significantly towards the end of the Cretaceous protection, it is possible that the climate became too chilly for dinosaurs. In contrast, other species having protection, such as the mammals and birds, were able to survive.
