Read the following passage and choose the best answer (A, B, C, D):
In the 1960s, it took pop and rock groups one or two days to record other their songs. Nowadays, it can take months and months. Many rock groups begin by recording only one instrument, for example, the voice. Then they record (1)________ instruments – electric piano, synthesizer, guitars, drums and so on. Next, they might use a computer to add special effects. Finally, they ‘mix’ all the instruments until they get the sound that they want. This means that a CD or cassette will always sound very different from a (2) ______ concert. Music engineers have developed a new computer programme that will change the future of music. A computer can analyze a singer’s voice. Then if you give the computer the (3)_________ and music of a song, the computer can ‘sing’ it in that voice. This means that a singer only needs to record one song and the computer can then sing other songs in the singer’s own voice. Singers can sing new songs many years after they have died. Most of us listen to music for pleasure, but for the record companies, music is a product, the same as soap powder. (4)___________ a record company finds a new group (or ‘band’), they first try to develop the band’s ‘profile’. They will try to create an ‘image’ for the band that they think will attract young people. Instead of allowing the band’s full artistic freedom, they will often (5)_______ the band what they should wear, what they should say and how they should sing and play. In recent year, many rock groups have started their own record companies because they say that the big companies are too commercial

It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern ways; that they are possessive and dominant; that they do not trust their children to deal with crises; that they talk too much about certain problems, and that they have no sense of humor, at least in parent-child relationships. I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when they were young. Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers of vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are leaders in style and taste. Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog; you cannot win; but at least you keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself. If you plan to control your life, cooperation can be part of that plan. You can charm others, especially your parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.

Sylvia Plath’s semi-autobiographical 1963 book “The Bell Jar” is most likely to be found in a sophomore English class, pored over by high-school students. But recently at Squarefoot, a commercial real estate company based in Manhattan, it was the chosen book title for the office book club. “People really latched onto [“The Bell Jar”] and talked about women’s roles in the workplace,” says Eliza Bell, people-operations manager. “The book club has been a bonding opportunity. People are able to learn about each other, and it’s really nice to talk about stuff that isn’t work-related. ‘The Bell Jar’ really brought that out, and we were able to talk about diversity initiatives.” Over the summer, the book pick was “The Hate U Give,” the 2017 young adult novel by Angie Thomas. The monthly club meets during a lunch that is provided by the company. In its first iteration, the club met after work and read business books: Not surprisingly, people weren’t quite as enthusiastic about that initiative. The club is the brainchild of CEO Jonathan. Wasserstrum, who is passionate about reading. There are some rules: At the beginning everyone has a chance to express what they liked or didn’t like. “If someone goes on a rant, it’s important to change the topic and move to another one,” says Bell. “When we read ‘The Last Lecture’ [the 2008 bestseller co-authored by the late Randy Pausch] for instance, it got a little heated.” What makes for a good pick? “We need an aspect of it to get people excited. It’s important that the books are ones people will have opinions on. People can learn from all sorts of different books,” says Bell. “And they have to be less than 250 pages.”  
2. The word “diversity” in paragraph 1 can be replaced by ______

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 following questions:
After inventing dynamite, Swedish-born Alfred Nobel became a very rich man. However, he foresaw its universally destructive powers too late. Nobel preferred not to be remembered as the inventor of dynamite, so in 1895, just two weeks before his death·, he created a fund to be used for awarding prizes to people who had made worthwhile contributions to humanity. Originally there were five awards: literature, physics, chemistry, medicine, and peace. Economics was added in 1968, just sixty-seven years after the first awards ceremony.
Nobel's original legacy of nine million dollars was invested, and the interest on this sum is used for the awards which vary from $30,000 to $125,000. Every year on December 10, the anniversary of Nobel's death, the awards (gold medal, illuminated diploma, and money) are presented to the winners. Sometimes politics plays an important role in the judges' decisions. Americans have won numerous science awards, but relatively few literature prizes.
No awards were presented from 1940 to 1942 at the beginning of World War 11. Some people have won two prizes, but this is rare; others have shared their prizes.

The word “legacy” in the second paragraph means most nearly the same as

Read the following passage and choose the best answer (A, B, C, D):
The year was 1810, the place was southern Germany, Bavaria, and life was hard. It was the month of October and all of the countryside had been working day and night to finish their fall harvest and prepare for the onset of winter. While the plow horses were working and the farmers’ days were filled from sun up to sun down, there were some other preparations being made as well. Prince Ludwig I and his entire court were preparing for his upcoming marriage to Princess Therese of Sachsen-Hildurghausen. The grand wedding was to take place on the 12th, right in the middle of the harvest. As you know any wedding can be difficult to plan, but when you’re a prince it can be even more stressful. The invitations had gone out, the garments had been made and the location had been selected. The big event was to be held in a magnificent “Weise” (meadow) just outside the gates of Munich. As the big day approached, the countryside and town, in fact all of Bavaria was a buzz with talk of the big day. Everyone was planning on attending as they were all exhausted from the harvest and it was really the last chance before the long, cold days of winter to get out and blow off some steam. On the 12th, the ceremony went off without a hitch. The weather was perfect, the bride looked beautiful and about 40,000 guests were in attendance. The reception, as you can imagine, was one of the biggest parties history had ever seen with copious amounts of beer and massive quantities of food being devoured. It was a reception fit for a prince. And this prince was absolutely ecstatic. Ludwig I was so taken with all of his guests that he planned a special treat for them. The prince knew that all of his subjects were huge fans of horseracing so he planned to conclude the event with a somewhat impromptu horse race across the great meadow. When the townspeople heard of this they erupted in a jubilant cry Zicke Zacka, Zicke Zacka, Hoy, Hoy, Hoy. This is still chanted in the beer tents of today’s Oktoberfest celebrations. It was then and there that they decided unanimously to rename the wiese Theresiewiese (Therese Meadow) in honor of the Prince’s new bride. This was their humble way of welcoming her to town. To this day that very meadow still bears her name. After a spectacular day and night — and probably more than a couple of hangovers — the great event came to an end. It was the following fall as the townspeople began to reminisce about the great time they had had the previous year (as do many of our Oktoberfest guests tend to do around the fall) that they decided to honor their prince and celebrate his wedding anniversary in much the same way. King Maximillian agreed, but this party was to be even bigger, better and longer than the first. The event became an annual celebration. And that my friends is how the Oktoberfest tradition began and continues today. As a side note, the beer that was poured all those years ago and that has been continually served at every Oktoberfest in Munich since will now be served at the Big Bear Lake Oktoberfest. The very same beer flowing from the taps in Munich, Germany will be the beer flowing from our taps in humble Big Bear Lake. And like the beer, our Burgermeister just happens to be a true German original as well.

Mohammed BK, who aims to connect Somalis in Bristol with their heritage, has been  confirmed for the Somali Week Festival, in 2020. Mohammed BK has been named as “cultural ambassador” for the Somali community. Ayan Mohamoud who is UK’s Somaliland Ambassador told the BBC he will now become a fixed part of the annual festivities. She said: “Young people who don’t speak Somali at all have memorised his music word-for-word and that is something that has never been done before by any Somali artist. He has been touring the country promoting citizenship and cultural unity throughout his career.”  Susan Elmi, 25, has been a fan of Mohammed BK for many years. She said: "In the Somali culture many people communicated their emotions and thoughts through songs and poetry and this is going back centuries. This man is bringing that back and making the younger generation question and explore our rich legacy. I think it’s just what the Somali Diaspora needs to say well connected to the identity.”  Mohammed BK also promotes education and advises young people to “use their time and resources wisely here in the UK because that is something their parents sacrificed fleeing from their homeland”. He added: “I thought to myself if I have that much influence on thousands and thousands of young people from my community, I need to put my platform to good use in encouraging them to do good and seek opportunities”. Festival fan Ameira Hassan, 45, said: “It’s a huge thing for our kids to take part in their history and culture. It’s important to us because they are learning a lot. Twenty years ago we never used to have anything like this in the UK and our kids never had any knowledge of the Somali culture.”

Read the following passage and choose the best answer (A, B, C, D):
A new study shows that urbanization shifts this seasonal cue in nuanced ways, with cities in cold climates triggering earlier spring plant growth and cities in warm climates delaying it. The study also found that the urban heat island effect, the phenomenon in which cities are warmer than their surroundings, is not the only culprit behind the shift, suggesting that other aspects of urbanization, such as pollution, changes in humidity and fertilizer runoff, may also influence plants’ seasonal patterns.  Researchers analyzed millions of observations of 136 plant species across the U.S. and Europe to study how regional temperature and the local density of people-a proxy for urbanization—affect when plants sprout leaves and blossoms. Their results revealed a complex story: Separately, warmer temperatures and higher population density each spurred earlier springs. A 3.6-degree Fahrenheit increase in temperature bumped up plants’ production of leaves and flowers by about five and six days, respectively. A fourfold increase in human population density advanced flowering and leaf production dates by about three days. But the team found that when these two factors worked together, local temperature had an outsized influence. In cold regions—areas with an average November-to-May temperature of about 18 degrees-plants produced leaves and flowers about 20 days earlier in locations with about 26,000 people per square mile, compared with equally frigid wildland. When an area’s average November-to-May temperature jumped to 68, however, leaves and flowers appeared four and six days later, respectively, in locations with about 26,000 people per square mile, compared with equally balmy wildland. In New York, for example, plants are likely sprouting leaves about 9.5 days earlier and blossoms eight days earlier than uninhabited regions with the same temperature. Jacksonville, in contrast, is likely pushing leaf production later by about one day and flowers by about half a day, with leaves appearing two days later and flowers a day later in Houston.  Even after accounting for urban heat islands, the team’s models revealed cities significantly affect plants’ springtime growth. “Not only are there other things going on, but they actually matter quite a lot,” said study co-author Brian Stucky, Florida Museum research scientist. Plants may not be the only organisms affected by seasonal shifts, he added. “Seasons are such a big part of our lives. We define our world around seasonal things. Those rhythms are what we think of as the normal way the world works.”

Read the following passage and choose the best answer (A, B, C, D):
Books have been around for thousands of years. When ancient civilizations first started developing writing systems, they would write on just about anything, from stone to tree bark. Ancient Egyptians were the first to use paper-like materials, called “papyrus”, which they made by pounding flat the woven stems of the papyrus plant. It was not long before the ancient Egyptians began gluing together papyrus sheets to form scrolls, which were the first steps toward books as you know. The birthplace of bookbinding is considered to be India in the 2nd century B.C., where Hindi scribes would bind palm leaves that were etched with religious texts between two wooden boards using twine. The technique became popular in the Middle East and Eastern Asia, and spread to the Romans by the 2nd century A.D. In the mid-15th century, German Johannes Gutenberg invented the first mechanical printing press. His invention was revolutionary because it enabled mass production of booksfor the first time. Before the printing press, a few pages per day could be produced by handcopying. Afterward, printing presses could produce as many as 3,600 pages per day. Today, modern publishers take advantage of incredible advances in technology to produce books in many sizes and shapes very quickly. Although there are many types of processes and machines available, most processes involve similar steps. Printers print the text of a book on large sheets of paper, sometimes as large as a newspaper page. Working with large volumes of paper allows printers to lower costs and produce books more efficiently.The large sheets are then cut into smaller pages that are still about twice the size of a finished book. The smaller pages are then divided into small groups, folded in half, and sewn together. Lastly, the folded and sewn pages are cut down to their finished size and glued to the spine of the final book’s cover. Depending on the quality of the book, additional finishing touches may be added, such as blank pages at the front and back of the book or special tape around the edges of the cover to increase durability. Although printed books may never go away completely, today’s readers will most certainly soon become more familiar with e-books. “E-book” refers to an electronic book, which is simply the text of a book displayed electronically, either via the Internet, a CD-ROM, a tablet, an e-book reader, or even a mobile phone. As electronic devices, such as tablets and mobile phones, become more commonplace, e-books are expected to become more and more popular. One of the benefits of e-books is that they save paper, which helps the environment by reducing the demand for trees

As places transformed, so did the people. When researchers at Yale University and the University of Westminster studied what images people associated with climate change, they found a shift this decade. When they began their study in 2003, the majority of people surveyed thought of melting polar ice. By 2016, more and more people had weather top of mind. Climate, to be clear, is not weather. It’s the difference between a trend and a one-off event. But with wetter storms and hotter summers unfolding over the course of the decade, people were making new connections between climate change and the weather. Seeing climate change through the lens of something they experience every day opens the door for people to see the weight of the issue over their own lives. “Americans are just beginning to connect the dots and to say, wait a second, what’s going on here,” says Anthony Leiserowitz, a lead author of the study and director of the Yale Program on Climate Change Communication. “There’s been this increasing dawning of awareness among many Americans that climate change is actually starting to harm people here and now.” New renewable energy projects outpaced new fossil fuel installations in worldwide growth for the first time in 2015. In a pivotal moment for the whole planet, every country on Earth agreed to take on climate change when they adopted the Paris climate accord in 2015. That committed countries to reducing their greenhouse gas emissions enough to keep the Earth from warming beyond roughly 1.5 degrees Celsius above pre-industrial levels, a threshold that could be catastrophic for people and ecosystems if it’s crossed. It was the culmination of years of political wrangling. “It is rare to have the opportunity in a lifetime to change the world,” former French president François Hollande told delegates gathered on the final day of negotiations. “Seize it so that the planet can live on, so that humanity can live on.” But cooperation, even when the health of the whole planet is on the line, can be a fragile, fleeting thing. After Donald Trump was elected president in 2016, he began the process of formally withdrawing the US from the Paris accord. One by one, Trump backtracked on existing federal efforts to cut down on pollution, too. The words “climate change” began disappearing from government websites and documents

If parents bring up a child with the sole aim of turning the child into a genius, they will cause a disaster. According to several leading educational psychologists, this is one of the biggest mistakes which ambitious parents make. Generally, the child will be only too aware of what his parents expect, and will fail. Unrealistic parental expectations can cause great damage to children.
However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a sensible way, the child may succeed in doing very well — especially if the parents are very supportive of their child. Michael Collins is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers twice a week for violin lessons. Michael's mother knows very little about music, but his father plays the trumpet in a large orchestra. However, he never makes Michael enter music competitions if he is unwilling.
Winston Smith, Michael's friend, however, is not so lucky. Both his parents are successful musicians, and they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him for every piano competition held. They are very unhappy when he does not win. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.

If you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn’t forget the plants, without whose prior invasion of the land, none of the other migrations could have happened. Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thoroughgoing land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales (including the small whales we call dolphins) and dugongs, with their close cousins, the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don’t even come ashore to breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches. There is evidence that all modern turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modern turtles and tortoise. You might wonder how we can tell whether fossil animals lived in land or in water, especially if only fragments are found. Sometimes it’s obvious. Ichthyosaurs were reptilian contemporaries of he dinosaurs, with
fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs.

Russia offers to establish an organization with the participation of Russia, the US, EU  states and other countries in order to resolve the issues in the Persian Gulf, Russian President Vladimir Putin stressed on Thursday during the plenary session of the Valdai Discussion Club.  "I would like to remind you that following this logic, Russia has come up with the concept of ensuring collective security in the Persian Gulf in July of this year. I think that taking into account the volatile and unpredictable situation in the region, the idea remains topical. We offer to put aside our differences and mutual claims and to establish an organization for security and cooperation in the region basically from scratch, which would include the Gulf States and which could involve Russia, China, the US, the EU, India and other interested states as observers," he said.  On July 23, the Russian Foreign Ministry introduced a concept of collective security in the Persian Gulf region. The concept includes forming an initiative group to organize an international conference on security and cooperation in the Persian Gulf area, which would lead to the establishment of an organization for security and cooperation in the region. Besides, Moscow offered to establish demilitarized zones in the region, abandon permanent deployment of units of non-regional states and establish military hotlines. Earlier, during a joint press conference on the outcomes of the talks with Russian Foreign Minister Sergey Lavrov, Iranian top diplomat Mohammad Javad Zarif welcomed the Russian initiative. He added that Iran offers to create a coalition on security in the Persian Gulf, including Iraq, Saudi Arabia, Bahrain, the United Arab Emirates, Qatar, Oman and Kuwait under the auspices of the UN.

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:
Under certain circumstances, the human body must cope with gases at greater-than-normal atmospheric pressure. For example, gas pressures increase rapidly during a drive made with scuba gear because the breathing equipment allows divers to stay underwater longer and dive deeper. The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth in seawater, so that at 39 meters in seawater a diver is exposed to pressure of about 4 atmospheres. The pressure of the gases being breathed must equal the external pressure applied to the body,

otherwise breathing is very difficult. Therefore all of the gases in the air breathed by a scuba diver at 40 meter are present at five times their usual pressure. Nitrogen, which composes 80 percent of the air we breathe, usually causes a balmy feeling of well-being at this pressure. At a depth of 5 atmospheres, nitrogen causes symptoms resembling alcohol intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct effect on the brain of the large amounts of nitrogen dissolved in the blood. Deep dives are less dangerous if helium is substituted for nitrogen, because under these pressures helium does not exert a similar narcotic effect.
As a scuba diver descends, the pressure of nitrogen on the lungs increases. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues The reverse occurs when the diver surfaces, the nitrogen pressure in the lungs falls and the nitrogen diffuses from the tissues into the blood, and from the blood into the lungs. If the return to the surface is too rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles are formed. They can cause severe pains, particularly around the joints.
Another complication may result if the breath is held during ascent. During ascent from a depth of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend and even rupture. This condition is called air embolism.
To avoid this event, a diver must ascend slowly, never at a rate exceeding the rise of the exhaled air bubbles, and must exhale during ascent.

It can be inferred from the passage that which of the following presents the greatest danger to a diver?

Read the following passage and choose the best answer (A, B, C, D):
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime they will dry faster than in winter, when temperatures are colder. The energy used in both cases to change liquid water to water vapor is supplied by heat – supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored in water vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere. In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large-scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere
