Rachel Carson was born in 1907 in Springdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master's degree in 1933. In 1936, she was hired by the US Fish and wildlife service, where she worked most of her life. Carson's first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around Us, which provided a fascinating look beneath the ocean's surface, emphasizing human history as well as geology and marine biology. Her language had a poetic quality. Carson consulted no less than 1,000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers. In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokes men for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work was vindicated by a 1963 report of the President's Science Advisory Committee.

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

Read the following passage and choose the best answer (A, B, C, D):
Human’s avarice for ivory has resulted in thousands of unfathomable elephant atrocities and senseless suffering that has pushed the species to the brink of extinction. In 2015, the U.S. and China announced they will work together to enact a near complete ban on the import and export of ivory. As an industry that has largely been driven by China and, if substantiated, these claims could be a ray of light for one of the most endangered animals in the kingdom. However, as the famous saying goes, “for every action, there is an equal and opposite reaction.” With the worldwide attention on elephant ivory, hippo teeth, which can grow up to three-feet-long, have become the next target. Since the United Nations Convention on International Trade in Endangered Species officially imposed a ban on ivory trading in 1990, about 30,000 pounds per year of hippo teeth have been exported from Africa. On a recent trip to Kenya, I had the unfortunate displeasure of meeting these facts face-to-face. On the banks of the Mara River, the infamous transient point of the great wildebeest migration, I met a Conservancy Ranger, a local Kenyan, named Ivan. He led me along a narrow path above the riverbed to view pods of hippos. They clumped together in the river, every few minutes lifting their heads above the waterline to welcome my arrival. Despite their label as one of the most dangerous animals in Africa, they were playful to watch. Their tiny ears and eyes would appear from the murky river and then, with a splash, they would disappear. The river is everything to the hippo, Ivan explained, it is their lifeline. The only real time they leave the river is during their nightly ritual of traveling to nearby plains to consume grasses. Contrary to their aggressiveness, they are vegetarians. As we neared the end of our trek, we reached the Mara Bridge, spanning the divide between Kenya and Tanzania. An undeniable stench filled the air. Our gaze fell to the water beneath the structure, and as if to mark the metaphorical significance of the passage, lay a poached hippo. It had been killed the previous night, probably as it grazed unsuspectingly under the cover of darkness. They had found spear punctures in its body, and its teeth were missing. It had somehow, in unthinkable pain, made its way back to the river, its home, to die.

Read the following passage and choose the best answer (A, B, C, D):
In all the debate about conservation of natural landscapes, we must not forget that the 19th century also saw the development of interest in the cultural past. Although archaeology was around 100 years old at this point, at least in the Old World, it was largely an exercise in treasure hunting - digging up the treasures of the past as curiosities for museums or for the private collections of those who funded the dig. Changes in attitudes and law throughout the 19th century meant that monuments and artefacts were becoming part of the study of the past, no longer merely trinkets and curiosities, but indicators of a culture’s development and identity. Modern archaeology would not arrive until the 20th century and the concept of an archaeological landscape is younger still. The first laws to protect and conserve cultural heritage came into place in the late 19th and early 20th centuries in the developed countries. In the US, the first such law was the Antiquities Act in 1906 which gave the office of president the power to set aside areas of land as protected cultural assets, known as “National Monuments”. This law was in place until 1979 when it was replaced with the Archaeological Resources Protection Act but several other laws came into place before then that  required archaeologists to label and give proper contexts to monuments and artefacts. There was also a global movement to protect by law and provide resources and funds for monuments that were nationally important, but also those deemed significant to human civilization as a whole. Founded in 1945, has many responsibilities, one of the most important as far as archaeological conservation is concerned is the World Heritage List. The list began in 1975 as a recognition of globally important sites. The first 12 added on that first day included: L’Anse Aux Meadows in Canada, The Galapagos Islands, Quito in Ecuador, Krakow, and Mesa Verde National Park in the US. Today, there are over 1,000 cultural monuments and natural landscapes on this list. In the 21st century, it is common for countries to have laws in place to protect monuments, sites, and landscapes of cultural or historical importance and governmentestablished charities or government departments assigned to their management, upkeep or conservation. The threats to them and their conservation go beyond the issues of the 19th century (plunder and theft)

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:
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.

The phrase "crazy about" in the passage mostly means     .

Political and economic reforms launched in 1986 have transformed the country from  one of the poorest in the world, with per capita income around US $100, to lower middle income status within a quarter of a century with per capita income of around US$ 2,100 by the end of 2015.  Vietnam’s per capita GDP growth since 1990 has been among the fastest in the world, averaging 5.5 percent a year since 1990, and 6.4 percent per year in the 2000s. Vietnam’s economy continued to strengthen in 2015, with estimated GDP growth rate of 6.7 percent for the whole year.  The Vietnamese population is also better educated and has a higher life expectancy than most countries with a similar per capita income. The maternal mortality ratio has dropped below the upper-middle-income country average, while under-five mortality rate has fallen by half, to a rate slightly above that average. Access to basic infrastructure has also  improved substantially. Electricity is now available to almost all households, up from less than half in 1993. Access to clean water and modern sanitation has risen from less than 50 percent of all households to more than 75 percent.  Vietnam’s Socio-Economic Development Strategy (SEDS) 2011-2020 gives attention to structural reforms, environmental sustainability, social equity, and emerging issues of macroeconomic stability. It defines three “breakthrough areas”: promoting human resources/skills development (particularly skills for modern industry and innovation), improving market institutions, and infrastructure development. In addition, the five-year Socio-Economic Development Plan 2011-2015 focused on three critical restructuring areas - the, banking sector, state-owned enterprises and public investment that are needed to achieve these objectives. The recent draft of the SEDP 20162020 acknowledges the slow progress of the reform priorities of the SEDP 2011-2015. With agriculture still accounting for almost half the labor force, and with significantly lower labor productivity than in the industry and services sectors, future gains from structural transformation could be substantial. The transformation from state to private ownership of the economy is even less advanced. The state also wields too much influence in allocating land and capital, giving rise to heavy economy wide inefficiencies. So, adjusting the role of the state to support a competitive private sector-led market economy remains a major opportunity. This will be important for enhancing productivity growth which has been stagnating for a long time.

Pollution is a threat to many species on Earth, but sometimes it can cause species to thrive. Such is the case with Pfiesteria piscicida. A one-celled creature called a dinoflagellate, Pfiesteria inhabits warm coastal areas and river mouths, especially along the eastern United States. Although scientists have found evidence of Pfiesteria in 3,000-year-old sea floor sediments and dinoflagellates are thought to be one of the oldest life forms on earth, few people took notice of Pfiesteria.
Lately, however, blooms – or huge, dense populations – of Pfiesteria are appearing in coastal waters, and in such large concentrations the dinoflagellates become ruthless killers. The blooms emit powerful toxins that weaken and entrap fish that swim into the area. The toxins eventually cause the fish to develop large bleeding sores through which the tiny creatures attack, feasting on blood and flesh. Often the damage is astounding. During a 1991 fish kill, which was blamed on Pfiesteria on North Carolina’s Neuse River, nearly one billion fish died and bulldozers had to be brought in to clear the remains from the river. Of course, such events can have a devastating effect on commercially important fish, but that is just one way that Pfiesteria causes problems. The toxins it emits affect human skin in much the same way as they affect fish skin. Additionally, fisherman and others who have spent time near Pfiesteria blooms report that the toxins seem to get into the air, where once inhaled they affect the nervous system, causing severe headaches, blurred vision, nausea, breathing difficulty, short-term memory loss and even cognitive impairment.
For a while, it seemed that deadly Pfiesteria blooms were a threat only to North Carolina waters, but the problem seems to be spreading. More and more, conditions along the east coast seem to be favorable for Pfiesteria. Researchers suspect that pollutants such as animal waste from livestock operations, fertilizers washed from farmlands and waste water from mining operations have probably all combined to promote the growth of Pfiesteria in coastal waters.

What is true of Pfiesteria?

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

Read the following passage and choose the best answer (A, B, C, D):
The word noise is derived from the Latin word nausea, meaning “seasickness”. Noise is among the most pervasive pollutants today. Noise pollution can broadly be defined as unwanted or offensive sounds that unreasonably intrude into our daily activities. Noises from traffic, jet engines, barking dogs, garbage trucks, construction equipment, factories, lawn mowers, leaf blowers, televisions, boom boxes and car radios, to name a few, are among the audible litter that is routinely broadcast into the air. One measure of pollution is the danger it poses to health. Noise negatively affects human health and well-being. Problems related to noise include hearing loss, stress, high blood pressure, sleeplessness, fright, distraction, and lost productivity. Noise pollution also contributes to a general reduction in the quality of life and eliminates opportunities for tranquility. We experience noise in a number of ways. On some occasions, we can be both the cause and the victim of noise, such as when we are operating noisy appliances or equipment. There are also instances when we experience noise generated by others, just as people experience secondhand smoke. In both instances, noise is equally damaging physically. Secondhand noise is generally more troubling, however, because it is put into the environment by others, without our consent. The air into which secondhand noise is emitted and on which it travels is “a commons”. It belongs not to an individual person or a group, but to everyone. Please, businesses and organizations, therefore, do not have unlimited rights to broadcast noise the as they please, as if the effects of noise were limited only to their private property. Those that disregard the obligation to not interfere with other’ use and enjoyment of the commons by producing noise pollution are, in many ways, acting like a bully in a schoolyard. Although they may do so unknowingly, they disregard the rights of others and claim for themselves rights that are not theirs. The actual loudness of a sound is only one component of the negative effect noise pollution has on human beings. Other factors that have to be considered are the time and place, the duration, the source of the sound, and even the mood of the affected person. Most people would not be bothered by the sound of a 21-gun salute on a special occasion. On the other hand, the thump-thump of music coming from the apartment downstairs at 2a.m, even if barely audible, might be a major source of stress. The sound of neighbor’s lawn mower may be unobjectionable on a summer afternoon, but if someone is hoping to sleep late on a Saturday morning, the sound of a lawn mower starting up just after sunrise is an irritant

Read the following passage and choose the best answer (A, B, C, D):
The climate crisis is poised to deliver a severe blow to America’s most threatened animals, with a new study finding that almost every species considered endangered is vulnerable in some way to global heating. Of the 459 animal species listed as endangered by the US government, researchers found that all but one, or 99.8%, have characteristics that will make it difficult for them to adapt to rising temperatures. The California condor, once close to being completely wiped out, faces increased risk of contamination in hotter conditions. Key deer, found only in the Florida Keys, face losing habitat to the rising seas. Whole classes of animals including amphibians, mollusks and arthropods are sensitive to the greatest number of climate-related threats, such as changes in water quality, shifting seasons and harmful invasive species that move in as temperatures climb. Mammals, such as the north Atlantic right whale and Florida panther, also face increased hardships, albeit on fewer fronts than amphibians, mollusks and arthropods.  Despite the overwhelming peril faced by America’s endangered species due to the climate crisis, the report, published in Nature Climate Change, found a patchy response from the US government. Federal agencies consider just 64% of endangered species to be threatened by the climate crisis, while just 18% of listed species have protection plans in place. Astrid Caldas, a study co-author and a climate scientist at the Union of Concerned Scientists said: “While agencies have increasingly listed climate change as a growing threat to species whose survival is already precarious, many have not translated this concern into tangible actions, meaning a significant protection gap still exists.” Nearly half of Australian species are threatened by the climate crisis, researchers have found. A spokesman for the US Fish and Wildlife Service, which oversees the endangered species list, said that while a species may be sensitive to changes in the climate, this sensitivity may not be so severe as to warrant being put on the list. “Our process for determining this looks at five factors: threats to a species’ habitat, overutilization, disease or predation, existing regulatory mechanisms, and other factors that may affect its continued existence,” he said. “Through this scientifically rigorous process we examine and account for the effects of climate change.

In 2018 the Tchaikovsky Competition celebrated its 60th anniversary. While many things have changed in the country, in the world and in the people, the art of music has been showing its amazing vital power helping the performing art go through difficult times and contributing to its amazing ability to revive. It appears that the history of the Tchaikovsky Competition can be divided into three periods which in the terms of a well-known critic can be defined as the rise, the soaring and the descent. The rise refers to the first three Competitions (1958, 1962 and 1966) when the structure of the Competition was formed (the First Competition comprised two categories, the Second – three and the Third – four categories). The competition jury was a pool of renowned cultural figures. Under the special focus were the amazingly talented competitors and they exceeded all expectations. The winner of the piano contest of the I Competition became Van Cliburn, a US piano player who just after finishing his first program items became the object of admiration and a legend that was passed down in Russia and America for generations. His impressive performance was something that couldn’t be judged only from the professional point of view; our listener’s perception was almost irrational. Also, for long we remembered by names the other piano players taking part in the I Competition. Truly, Toyoaki Matsuura and Daniel  Pollack were brilliant virtuosos, if not genius. Besides, both Daniel Pollack and Van Cliburn studied under Rosina Levina, a famous Russian educator, i.e. they were kindred spirits for Russians. What was happening gave an impression of something truly exceptional and unmatched, and this was proved to be true during the many years of the Tchaikovsky Competition in the future. The II Competition was also truly amazing. In the piano category won Vladimir Ashkenazi, the Soviet virtuoso piano player, and an eccentric Englishman John Ogdon. In the violin contest the winner was Leningrad native Boris Gutnikov who had won all the competitions in which he had participated. At the III Competition there was a sensation: a Leningrad native 16-year-old Grigory Sokolov while not being considered by the critics as the most likely winner won the first prize in the piano contest; his charmingly fresh musicality and magical pianism turned the jury’s opinion in his favor despite the dissatisfaction of the Moscow audience over the jury’s choice.  
4. The word “jury” in paragraph 2 is closest in meaning to _______

Read the following passage and choose the best answer (A, B, C, D):
The term “generation gap” may have been coined not long ago but the problem itself is as old as the hills. All sorts of conflicts and misunderstanding between younger and older generations occur in probably every family. Adults complain about arrogance and insensitivity of young people whereas the latter claim that their parents have no idea about what they are going through. There seems to be no perfect solution to this problem as the young and the old find it difficult, if not impossible, to communicate and accept opposite views. The fact that teenagers develop different values from those held by their parents leads to numerous conflicts. There are many reasons why the problem of generation gap arises. First of all, the period of adolescence is difficult. Teenagers are not children any longer, but they are no adults yet. They search for a sense of identity and crave independence. On the other hand, they depend on their parents financially and still need their parent consent when they want to go out, go for holidays, buy something expensive, invite friends home, etc. Very often teenagers treat their parents like enemies especially when they are not permitted to do one thing or another. Obviously, it is understandable when parents insist a teenager returns home before midnight. They have a wide knowledge of the world and all kinds of risks involved – reckless youngsters see no danger in walking alone in the middle of the night or getting a lift from a stranger who might be a serial killer. When children grow up and start their own families they are able to admit that their parents were usually right, although a bit overprotective at times  However, we must remember that adolescence is the period of making important decisions. Sixteen or seventeen-year-olds want to choose their career path or at least develop their talents, which in turn will enable them to decide upon a job later on. Secondly, it is in their late teens when they form their lifelong friendships, go for their first dates, analyze what qualities they will look for in their future partners. Unfortunately, a lot of parents do not want to accept the fact that their child is growing up and has the sole right to choose who she or he wants to become in the future. Such mothers and fathers often have their own idea what their child’s life should be. To my mind, this kind of behavior is really harmful and it can result in a very serious family conflict. Every now and then we meet forty-year-old people who accuse their parents of making them study the subject they hated or marrying the person they never loved. The generation gap problem, which usually disappears a few years later, in such families turns into an emotional wound which might never heal and the feeling of a wasted life on both parts. To sum up, although conflicts between teenagers and their parents are unavoidable, they definitely do not have to lead to an open war. My advice to parents is to try and treat teenagers as their equal partners and to accept their ideas. Teenagers should respect their mothers and fathers more, and be always ready to discuss serious problems with them. All in all, who else loves them more than their parents do?
