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 elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 25 percent helium by weight and somewhat less than 75 percent hydrogen.
Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic rays are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn’t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.
Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significant greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.
However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperature were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled so sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formations of helium went on for only relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.Most of the helium in the universe was formed

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:
Why are there so many grandmothers and so few grandfathers? In other words, why do men die younger than women? Is this because men are afraid of getting old and helpless and so they prefer to die before that happens? Perhaps they fear to be left alone by their women and so decide to do the leaving first.
Many explanations are given for the fact that men die earlier than women. Men are stronger physically, yet women can hang on longer to life. Both men and women are emotional creatures but women are not afraid or ashamed to cry while men refuse to do so. They are afraid of being thought "soft". Some men, when they are upset, play loud music or dig in the garden to relieve their feelings. Many men like an orderly life so that they bury themselves in their work or want a wife with some children or long to take part in wars where there is a definite chain of command. There is a leader to give orders and a known enemy to fight against and defeat. All these make men feel they live in a rational world.
So the majority of men like a rational world. Rationality is fine but it does not include everything that makes life joyful and fun or even messy and frustrating. When a man refuses to cry he is refusing to accept that his emotions are part of him. Of course some men do not follow this pattern. Bob Hawke is capable of crying in public whereas Margaret Thatcher is probably incapable of crying at any time.
We need to cry because that shows our ability to suffer. If we do not suffer we are not really alive at all. Suffering can be creative or destructive. If we can all learn to cry and laugh and shout and dance openly, we are living creatively and adding something to the human race. We often say men suffer more from stress and therefore they die earlier. Are we not saying in another way that they do not know how to suffer in the right way – with tears and laughter instead of silence – and so they are miserable and just give up? That is just my theory of course. Have you a better one?What’s the writer’s opinion toward crying?

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:
In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.
Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.From the passage, it can be inferred that to solve our energy problems .

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:
If you ask any Vietnamese girl right now who she has a crush on, chances are you will encounter the name of the 20-year-old goalkeeper who plays for Vietnam national team. Bui Tien Dung made a name for himself in the AFC U23 Championship where he accurately blocked opponents' shots time after time and saved Vietnam’s chance at the championship in the process. Bui Tien Dung was born on February 28th, 1997 in a poor farming family in Thanh Hoa Province. Dung has loved soccer since he was a kid, but his family was so poor that they could not even
afford a plastic soccer ball for him and his brother. The Bui brothers had to resort to playing with balls made from scrap papers and old grapefruits.
Dung's parents recognized the brothers' passion for football and used the little money they had to support their sons' early training. When a big football club in the city announced a recruitment event, Dung convinced his younger brother to go to the tryout. He passed on the opportunity knowing that his parents could not afford to have both their sons gone to city.
While his younger brother training in the city, Dung's local training center went bankrupted and abruptly ended Dung's football career. For a year, instead of kicking balls, the young man worked as a construction worker to support his parents. He seemingly gave up on football.
Fate finally smiled on Dung when a football coach rediscovered him and sent him to train with a local football team. Reentering the football field, Dung wanted to play in a defense position but he was pushed to goalkeeping because of his height. At first, Dung was unhappy about his new position, but his parents advised him to follow and make the best out of it. And Dung did.
The young goalkeeper trained hard for his new position and patiently climbed up the ranks the following years. Through hard work, he was named the best goalkeeper of Vietnam's U19 division. Those who have worked with Dung described him as a likable young man. He is very respectful to others and speaks very little. However, when the gloves are on, the nice young man transforms into a fierce competitor and an unyielding goalkeeper.
At AFC U23 Championship, Dung finally reunited with his brother on the field. They fought battle after battle together with other amazing players on the team and helped Vietnam made history for Southeast Asian football.
Even though Vietnam came short of winning the championship, Dung and his teammates are already heroes and legends in the heart of Vietnamese people. They played fairly and lost with glory and grace.What is the passage mainly about?

Did you ever watch a video on the Internet? Maybe you used YouTube. YouTube is a Website where people can share their video. Today, YouTube is an important part of the Internet. However, that wasn’t always true.
YouTube started with a young man named Jawed Karim and two friends. One day, Karim was on the Internet. He wanted information about the 2004 tsunami in Southeast Asia. He found news stories about it, but he couldn't find any videos. This gave Karin an idea. He wanted to help people put video on the Internet. Karim told his friends about this idea. Together, they created a company - YouTube.
YouTube become a global success. Millions of people around the world Visited the Website. It was clear to Google, another Internet company, that YouTube had a lot of value. Google made a deal. It bought YouTube for $1.65 billion. As a result, YouTube investors and its employees made a lot of money. The three friends who started YouTube were very big investors. Therefore, they made an enormous amount of money.
Karim became very rich, and he continued to work toward his PhD. There was something else he wanted to do. He wanted to help young people go into business. He used money and experience to start a new company called Youniversity Ventures. This company helps young people who have good business ideas. It gives them advice and money to start Internet businesses. Milo is one business that students started with the help of Youniversity Ventures.
Milo is a shopping Website. It helps people find products in stores near their homes. Another example is AirBoB. This Web site helps people find for video conferences. People in different places can use this site to have business meetings.
Karim has some advice for students who want to start business. First, find a successful company. Do a lot of research about the company and the top people in the company. There, copy the way they do things. For students who wants to start Interner business, Karim is probably a very good example to copy.What does the word “This” 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.
Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.
In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.
High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.
A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time – consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.
According to the passage, the frame buffers mentioned in the third paragraph are used 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:
Dark matter in the universe is believed by some scientists to be a substance that is not readily observable because it does not directly refract light or energy. Its existence can only be deduced because of the effect that it has on surrounding matter. In fact, some members of the scientific community have argued that dark matter does not actually exist. Others, however, believe in its existence, in part because the scientific community does not have a complete understanding of gravita science. On the other hand, some would argue that it is the understanding of gravitational science that leads most scientists to believe in the existence of dark matter, because without dark matter, there are many cosmological phenomena
that are difficult to explain.
For example, dark matter in the universe may have a peculiar effect on the Milky Way galaxy. Some scientists believe that the interaction between dark matter and other smaller, nearby galaxies is causing the Milky Way galaxy to take on a warped profile. It has been asserted that not only does dark matter exist, it may also be responsible for the Milky Way’s unusual shape. The interaction referenced involves two smaller galaxies near the Milky Way, called Magellanic clouds, moving through an enormous amount of dark matter, which, in effect, enhances the gravitational pull that the two Magellanic clouds could have on the Milky Way and other surrounding bodies. Without the existence of the dark matter, the Magellanic clouds would not have sufficient mass to have such a strong effect on the bend of the Milky Way galaxy.
The strongest evidence for the validity of this hypothesis rests in Newtonian physics, and the hypothesis that anything with mass will exert a gravitational pull. The Milky Way and other galaxies with peculiar warped shapes are being molded by a gravitational force. However, there is nothing readily observable with sufficient mass that could cause such a high level of distortion via gravitational pull in the vicinity of the Milky Way. Therefore, something that is not easily observed must be exerting the necessary force to create the warped shape of the galaxy.
Aaron Romanowsky and several colleagues have questioned the effect that dark matter might have on galaxies. They point to the existence of several elliptical galaxies surrounded by very little dark matter as evidence that dark matter is not, in fact, the cause of the warped galaxies. While they do not claim that their findings should be interpreted to conclude that dark matter does not exist, they apparently believe that the results of their studies cast doubt on some of the conventional theories of galaxy formation and manipulation.
Several models constructed by researchers from the University of California at Berkeley, however, point to the idea that dark matter is the most likely explanation for the distorted shape of the Milky Way and other galaxies. Using computer models, they have mapped the likely interactions between certain galaxies and the surrounding dark matter, and those models have shown not only the possibility that dark matter is responsible for the warped shape of the Milky Way, but that the relationship between the dark matter and the Magellanic clouds is dynamic; the movement of the clouds through the dark matter seems to create a wake that enhances their gravitational influence on the Milky Way.The passage states that some members of the scientific community are reluctant to believe in the existence of dark matter because:

The Owners of the "News”
The role of the media is essentially defined by the manipulation of information-oriented towards the control of "public opinion", but their goals are not social as described in the mythology of "journalistic objectivity".
The famous ethical flags of journalism: fairness, objectivity and freedom of expression, are nothing more than myths concealing the billionaire media business that moves daily market information on a global scale. The process of manufacturing and distributing information is not motivated by the need to "inform" but by the capitalist need to sell news. To do this, the media, like any capitalist company, generates massive consumer needs in society and plots information strategies aimed at encouraging business growth, positioning themselves in order to successfully compete in the market.
First, information is a commodity to produce economic returns like any other commercial product offered in the capitalist market. In functional terms (and beyond the legend that is produced around it) the newspaper businesses are not guided by social purposes but for the pursuit of economic gain. Secondly, in the light of the strategic nature of the communication function to develop from the point of view of preservation of the "governance", system the media is a key tool for the control and manipulation of the economic, political and social processes.
In the news business, like any business venture, the media only works for those who can pay for their "informative" services. This is why a relationship of mutual survival between the media, governments and major economic groups exists. These groups decide what is news and what is not and use this strategy to control political, economic and social trends.
True or False:
Journalism is a billion dollar business that moves information on a global scale.

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:
After twenty years of growing student enrollments and economic prosperity, business schools in the United States have started to face harder times. Only Harvard’s MBA School has shown a substantial increase in enrollment in recent years. Both Princeton and Stanford have seen decreases in their enrollments. Since 1990, the number of people receiving Masters in Business Administration (MBA) degrees, has dropped about 3 percent to 75,000, and the trend of lower enrollment rates is expected to continue.
There are two factors causing this decrease in students seeking an MBA degree. The first one is that many graduates of four-year colleges are finding that an MBA degree does not guarantee a plush job on Wall Street, or in other financial districts of major American cities. Many of the entry- level management jobs are going to students graduating with Master of Arts degrees in English and the humanities as well as those holding MBA degrees. Students have asked the question, “Is an MBA degree really what I need to be best prepared for getting a good job?” The second major factor has been the cutting of American payrolls and the lower number of entry-level jobs being offered. Business needs are changing, and MBA schools are struggling to meet the new demands.Which of the following descriptions most likely applies to Wall Street?

Researchers in the field of psychology have found that one of the best way to make an important decision, such as choosing a university to attend or business to invest in, involves the utilization of a decision worksheet. Psychologists who study optimization compare the actual decisions made by people to theretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets cam take, they are all similar in their essential aspects.
Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that all possible solutions to the problem. Next, the pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision.
Since most important problems are multifaceted, there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question "What will I do after graduation?" A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year.
A decision-making worksheet begins with a succinct statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones. Focusing on long-range goals, a graduating student might revise the question above to "What will I do after graduation that will lead to a successful career?"
Of the following steps, which occurs BEFORE the others in making a decision worksheet?

Martin Luther King, Jf., is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhood.
M.L, as he was called, was born in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was born. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.
M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.
M.L. was _______ by the atmosphere in which he grew up.

The concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. (A)
Three-quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. (B)
Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. (C)
The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water.

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:
Life expectancy is the period of time that a person can expect to live. Life expectancy varies greatly between genders and cultures. It used to be that women had a lower life expectancy than men (1 in every 4 women died in childbirth), but now they live an average of four to five years longer than men. Life expectancy has been increasing rapidly over the last centuries. With the advent of such modern miracles as sewers, medicine and a greater understanding of how diseases are spread, our life expectancy has increased by 25-30 years.
In developing countries like Swaziland, where there is a high HIV/ AIDS rate, life expectancy is as low as 32.6 years. In developed countries like Australia, life expectancy rates are as high as 81 years. There are an increasing number of factors which can cancel out the disadvantages you have. The one that we are looking at now is how your career can affect your life expectancy. Choosing the wrong career can result in a shorter life!
If you want your career to positively influence your life expectancy, you have to be made of money. That's right. Rich people in wealthy areas of England and France live 10 years longer than the people in poorer areas. Having a successful career has its drawbacks, too if the result of hard work is stress.
Stress can lead to a number of psychological disorders such as depression, anxiety, fatigue, tension and aggression. These conditions may result in a lack of concentration and an increase in serious injuries at work. They can also lead to high blood pressure and heart attacks which seriously affect life expectancy.
If you are worried that your job might decrease your life expectancy, you probably need to avoid careers on "dangerous jobs" list such as timber cutters, pilots, construction workers, roofer, truck drivers.
So if you don't want to kick the bucket at an early age, choose a career in something other than timber cutting, but above all, remember to relax.The phrase "kick the bucket" in the passage 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:
Less than a year ago marketing director, David Smith, 33 was behaving like a secet agent. He used to secretly taped all his conversations, he refused to sign his name and he would ask his secretary to check all his emails. Anything he wrote was photocopied and kept as “evidence”. But David isn’t mad, or even mildly eccertric. He suffers from ‘resposibility OCD’, one of more common form of obsessive compulsive disorder, or OCD, as it is usually known.
OCD is now recognized as the second most prevalent mental-health problem, after depression – and the number of reported cases is soaring. Experts estimate that 2% - 3% of the population suffer from the full-blown syndrome, with as many as one in five suffering from a milder form.
OCD sufferers are tortured by obsessional thoughts, such as worrying that their hands are contaminated by germs. The terrible anxiety is only relieved by performing a particular set of behaviours. Unfortunately, any sense of relief is short-lived, which is why the behaviour must be repeated again and again. OCD sufferers know their behavior is irrational, yet feel powerless to stop.
Common treatments are either antidepressants or behavioral therapy with a psychologist, but only 60% of patients show some improvement. However, a new treatment from America is bringing fresh hope to sufferers.
One of the OCD gurus and neuropsychiatrists, Jeffrey Schwartz, has designed the Four Steps program which employs meditation teachniques with the aim of teaching sufferers to manage their symptoms by themselves. “The goal is to learn to override false brain messages”, explains Schwartz.
There are different theories about what causes the disorder. Most experts recognize a genetic element that can be triggered by a stressful event. Schwartz believes that the OCD ‘worry circuit’ is a
direct result of faulty brain chemistry. ‘When someone experiences an OCD thought, one part of the brain knows quite clearly that the hand are not dirty’, explains Schwartz ‘Some part of the brain is standing apart from the symptoms, reflecting on the sheer bizarreness of it all. The objective is to harness this impartial spectator so that patients can use this healthy part of their brain to resist the compulsions.’
