Foot racing is a popular activity in the United States. It is seen not only as a competitive sport but also as a way to exercise, to enjoy the camaraderie of like-minded people, and to donate money to a good cause. Though serious runners may spend months training to compete, other runners and walkers might not train at all. Those not competing to win might run in an effort to beat their own time or simply to enjoy the fun and exercise. People of all ages, from those of less than one year (who may be pushed in strollers) to those in their eighties, enter into this sport. The races are held on city streets, on college campuses, through parks, and in suburban areas, and they are commonly 5 to 10 kilometers in length.
The largest foot race in the world is the 12-kilometer Bay to Breakers race that is held in San Francisco every spring. This race begins on the east side of the city near San Francisco Bay and ends on the west side at the Pacific Ocean. There may be 80,000 or more people running in this race through the streets and hills of San Francisco. In the front are the serious runners who compete to win and who might finish in as little as 34 minutes. Behind them are the thousands who take several hours to finish. In the back of the race are those who dress in costumes and come just for fun. One year there was a group of men who dressed like Elvis Presley, and another group consisted of firefighters who were tied together in a long line and who were carrying a fire hose. There was even a bridal party, in which the bride was dressed in a long white gown and the groom wore a tuxedo. The bride and groom threw flowers to bystanders, and they were actually married at some point along the route.

In 1959 Xerox created the first plain paper copy machine. It was one of the most  successful products ever. The company name Xerox grew into a verb that means “to copy,” as in “Bob, can you Xerox this for me?” Around 50 years later, the same thing happened to Google. Their company name grew into a verb that means “to do an internet search.” Now everyone and their grandma knows what it means to Google it.  Unlike Xerox, Google wasn’t the first company to invent their product, not by a long shot. Lycos released their search engine in 1993. Yahoo! came out in 1994. AltaVista began serving results in 1995. Google did not come out until years later, in 1998. Though a few years difference may not seem like much, this is a major head start in the fast moving world of tech. So how did Google do it? How did they overtake their competitors who had such huge leads in time and money? Maybe one good idea made all the difference.  There are millions and millions of sites on the internet. How does a search engine know which ones are relevant to your search? This is a question that great minds have been working on for decades. To understand how Google changed the game, you need to know how search engines worked in 1998. Back then most websites looked at the words in your query. They counted how many times those words appeared on each page. Then they might return pages where the words in your query appeared the most. This system did not work well and people often had to click through pages and pages of results to find what they wanted.  Google was the first search engine that began considering links. Links are those blue underlined words that take you to other pages when you click on them. Larry Page, cofounder of Google, believed that meaningful data could be drawn from how those links connect. Page figured that websites with many links pointing at them were more important than those that had few. He was right. Google’s search results were much better than their rivals. They would soon become the world’s most used search engine.  It wasn’t just the great search results that led to Google becoming so wellliked. It also had to do with the way that they presented their product. Most of the other search engines were cluttered. Their home pages were filled with everything from news stories to stock quotes. But Google’s homepage was, and still is, clean. There’s nothing on it but the logo, the search box, and a few links. It almost appears empty. In fact, when they were first testing it, users would wait at the home page and not do anything. When asked why, they said that they were, “waiting for the rest of the page to load.” People couldn’t imagine such a clean and open page as being complete. But the fresh design grew on people once they got used to it.

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:
In the course of its history, human inventions have dramatically increased the average amount of energy available for use per person. Primitive peoples in cold regions burned wood and animal dung to heat their caves, cook food, and drive off animals by fire. The first step toward the developing of more efficient fuels was taken when people discovered that they could use vegetable oils and animal fats in lieu of gathered or cut wood. Charcoal gave off more intensive heat than wood and was more easily obtainable than organic fats. The Greeks first began to use coal for metal smelting in the 4th century, but it did not come into extensive use until the Industrial Revolution.
In the 1700s, at the beginning of the Industrial Revolution, most energy used in the United States and other nations undergoing industrialization was obtained from perpetual and renewable sources, such as wood, water streams, domesticated animal labor, and wind. These were predominantly locally available supplies. By mid-1800s, 91 percent of all commercial energy consumed in the United States and European countries was obtained from wood. However, at he beginning of the 20th century, coal became a major energy source and replaced wood in industrializing countries. Although in most regions and climate zones wood was more readily accessible than coal, the latter represents a more concentrated source of energy. In 1910, natural gas and oil firmly replaced coal as the main source of fuel because they are lighter and, therefore, cheaper to transport. They burned more cleanly than coal and polluted less. Unlike coal, oil could be refined to manufacture liquid fuels for vehicles, a very important consideration in the early 1900s, when the automobile arrived on the scene.
By 1984, non-renewable fossil fuels, such as oil, coal, and natural gas, provided over 82 percent of the commercial and industrial energy used in the world. Small amounts of energy were derived from nuclear fission, and the remaining 16 percent came from burning direct perpetual and renewable fuels, such as biomass. Between 1700 and 1986, a large number of countries shifted from the use of energy from local sources to a centralized generation of hydropower and solar energy converted to electricity. The energy derived from non-renewable fossil fuels has been increasingly produced in one location and transported to another, as is the case with most automobile fuels. In countries with private, rather than public transportation, the age of non-renewable fuels has created a dependency on a finite resource that will have to be replaced.
Alternative fuel sources are numerous, and shale oil and hydrocarbons are just two examples. The extraction of shale oil from large deposits in Asian and European regions has proven to be labor consuming and costly. The resulting product is sulfur-and nitrogen-rich, and large scale extractions are presently prohibitive. Similarly, the extraction of hydrocarbons from tar sands in Alberta and Utah is complex. Semi-solid hydrocarbons cannot be easily separated from the sandstone and limestone that carry them, and modern technology is not sufficiently versatile for a large-scale removal of the material. However, both sources of fuel may eventually be needed as petroleum prices continue to rise and limitations in fossil fuel availability make alternative deposits more attractive.

The National Automobile Show in New York has been one of the top auto shows in the United States since 1900. On November 3 of that year, about 8,000 people looked over the "horseless carriages." It was the opening day and the first opportunity for the automobile industry to show off its wares to a large crowd; however, the black-tie audience treated the occasion more as a social affair than as a sales extravaganza. It was also on the first day of this show that William McKinley became the first U.S. president to ride in a car.
The automobile was not invented in the United States. That distinction belongs to Germany. Nikolaus Otto built the first practical internal-combustion engine there in 1876. Then, German engineer Karl Benz built what are regarded as the first modern automobiles in the mid-1880s. But the United States pioneered the merchandising of the automobile. The auto show proved to be an effective means of getting the public excited about automotive products.

By happenstance, the number of people at the first New York show equaled the entire car population of the United States at that time. In 1900,10 million bicycles and an unknown number of horse-drawn carriages provided the prime means of personal transportation. Only about 4,000 cars were assembled in the United States in 1900, and only a quarter of those were gasoline powered. The rest ran on steam or electricity.

After viewing the cars made by forty car makers, the show's audience favored electric cars because they were quiet. The risk of a boiler explosion turned people away from steamers, and the gasoline-powered cars produced smelly fumes. The Duryea Motor Wagon Company, which launched the American auto industry in 1895, offered a fragrant additive designed to mask the smells of the naphtha that it burned. Many of the 1900 models were cumbersome—the Gasmobile, the Franklin, and the Orient, for example, steered with a tiller like a boat instead of with a steering wheel. None of them was equipped with an automatic starter.

These early model cars were practically handmade and were not very dependable. They were basically toys of the well-to-do. In fact, Woodrow Wilson, then a professor at Princeton University and later President of the United States, predicted that automobiles would cause conflict between the wealthy and the poor. However, among the exhibitors at the 1900 show was a young engineer named Henry Ford. But before the end of the decade, he would revolutionize the automobile industry with his Model T Ford. The Model T, first produced in 1909, featured a standardized design and a streamlined method of production—the assembly line. Its lower costs made it available to the mass market.

Cars at the 1900 show ranged in price from $1,000 to $1,500, or roughly $14,000 to $21,000 in today's prices. By 1913, the Model T was selling for less than $300, and soon the price would drop even further. "I will build cars for the multitudes," Ford said, and he kept his promise

Read the following passage and choose the best answer (A, B, C, D):
Coal, oil and gas get more than $370bn a year in support, compared with $100bn for renewables, the International Institute for Sustainable Development (IISD) report found. Just 10-30% of the fossil fuel subsidies would pay for a global transition to clean energy, the IISD said. Ending fossil fuel subsidies has long been seen as vital to tackling the climate emergency, with the G20 nations pledging in 2009 to phase them out, but progress has been limited. The new analysis shows how redirecting some of the fossil fuel subsidies could decisively tip the balance in favour of green energy, making it the cheapest electricity available and instigating a rapid global rollout. The transition from polluting fossil fuels to clean energy is already under way. Annual investment in renewables has been greater than that in fossil fuel electricity generation since 2008 and new renewable capacity has exceeded fossil fuel power each year since 2014. But progress is slow compared with the urgency required, said Bridle. “There is no question that renewables can power the energy system,” he said. “The question now is can we transit quickly enough away from fuels like coal, and subsidy reform is a very obvious step towards that.  Reform of fossil fuel subsidies could have a significant impact on global heating. An earlier IISD study of 20 countries with large fossil fuel subsidies found that a 30% swap to renewables would lead to emissions reductions of between 11% and 18%. Most experts define fossil fuel subsidies as financial or tax support for those buying fuel or the companies producing it. The IMF also includes the cost of the damage fossil fuel burning causes to climate and health, leading to an estimate of $5.2tn of fossil fuel subsidies in 2017, or $10m a minute. Ending the subsidies would cut global emissions by about a quarter, the IMF estimates, and halve the number of early deaths from fossil fuel air pollution. Bridle said funding fossil fuel subsidies was “madness”, but said ending them could cause short-term price rises and political difficulties, as the benefits of lower costs in the future and reduced air pollution are less obvious. “There are political problems but it is worth persevering because the prize is so big,” he said. “You have to bring people along with you.” Gençsü said governments must ensure that the most vulnerable people were not adversely affected by changes.

Read the following passage and choose the best answer (A, B, C, D):
Naturalists in the developed countries were largely split between conservationists and  preservationists. This battle is no better demonstrated in the US than during the Progressive Era of 1890-1920.  While the existing economic paradigm was one of laissez-faire economics that many felt was damaging the natural environment and integrity of natural resources, the conservationist movement led by Theodore Roosevelt was deeply concerned about the wastage and harm it was doing to the land, leading to a large number of game species in the US on the brink of extinction in less than a century. Then there were the preservationists who argued that the proposals of the emerging conservationists did not go far enough. This was certainly the view of John Muir who believed that there was still too much concern for the economic value of land rather than the need for preservation of pristine landscapes. Muir’s Sierra Club made a stand with the development of the Hetch Hetchy Dam in Yosemite, arguing that the land should be kept pristine and the valley protected.  As president, Roosevelt pushed strongly for conservation issues which may be the reason they eventually won the day. During his term in office, around 230m acres of land were put under Federal protection, established the US Forestry Service, and created five national parks, and several national forests. That’s not to say that preservationists did not have their victories. In the 1960s, the Wilderness Actset aside large tracts of land with minimal human impact and of particular cultural, scientific, or natural interest. In these areas, logging, mining and other industrial activities are prohibited and there are strong protections in place to maintain the integrity of natural water sources partly for the ecosystem and partly for industrial and commercial developments downstream of the water flow.

An American game that has traveled well is basketball, now played by more than 250 million people worldwide in an organized fashion, as well as by countless others in “pick-up” games. Basketball originated in 1891 when a future Presbyterian minister named James Naismith (1861-1939) was assigned to teach a physical education class at a Young Men’s Christian Association (YMCA) training school in Springfield, Massachusetts. The class had been noted for being disorderly, and Naismith was told to invent a new game to keep the young men occupied. Since it was winter and very cold outside, a game that could be played indoors was desirable.  Naismith thought back to his boyhood in Canada, where he and his friends had played “duck on a rock,” which involved trying to knock a large rock off a boulder by throwing smaller rocks at it. He also recalled watching rugby players toss a ball into a box in a gymnasium. He had the idea of nailing up raised boxes into which players would attempt to throw a ball. When boxes couldn’t be found, he used peach baskets. According to Alexander Wolff, in his book 100 Years of Hoops, Naismith drew up the rules for the new game in “about an hour.” Most of them still apply in some forms today.  Basketball caught on because graduates of the YMCA school traveled widely, because Naismith disseminated the rules freely, and because there was a need for a simple game that could be played indoors during winter. Naismith’s legacy included the first great college basketball coach, Forrest “Phog” Allen (1885-1974), who played for Naismith at the University of Kansas and went on to win 771 games as a coach at Kansas himself. Among Allen’s star players was Wilt Chamberlain, who became one of professional basketball’s first superstars – one night in 1962, he scored a record 100 points in a game.  The first professional basketball league was formed in 1898; players earned $2.50 for home games, $1.25 for games on the road. Not quite 100 years later, Juwan Howard, a star player for the Washington Bullets (now called the Washington Wizards), had competing offers of more than $100 million over seven seasons from the Bullets and the Miami Heat.  Many teams in the National Basketball Association now have foreign players, who return home to represent their native countries during the Olympic Games. The so-called Dream Team, made up of the top American professional basketball players, has represented
the United States in recent Olympic Games. In 1996 the Dream Team trailed some opponents until fairly late in the games. In Athens in 2004 Argentina took home the gold, the first time a Latin American country won the basketball honor.

Read the following passage and choose the best answer (A, B, C, D):
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.

The relationship between Britain and the US has always been a close one. Like all close relationship it has had difficult times. The US was first a British colony, but between 1775 and 1783 the US fought a war to become independent. The US fought the British again in the War of 1812. In general, however, the two countries have felt closer to each other than to any other country, and their foreign policies have shown this. During World War I and World War II, Britain and the US supported each other. When the US looks for foreign support, Britain is usually the first country to come forward and it is sometimes called “the 51st state of union”. But the special relationship that developed after 1945 is not explained only by shared political interests. An important reason for the friendship is that the people of the two countries are very similar. They share the same language and enjoy each other’s literature, films and television. Many Americans have British ancestors, or relatives still living in Britain. The US government and political system is based on Britain’s, and there are many Anglo-American businesses operating on both sides of the Atlantic. In Britain some people are worried about the extent of US influence, and there is some jealousy of its current power. The special relationship was strong in the early 1980s when Margaret Thatcher was Prime Minister in Britain and Ronald Reagan was President of the US.

Like many social and political movements, the green movement has been  strengthened and annealed by the forces that oppose it. After James Watt was appointed to lead the Department of the Interior, for instance, membership in the Sierra Club grew from 183,000 to 245,000 in just 12 months.  Today, the green movement is again defined and galvanized by its command of issues like global warming and climate change, wetlands preservation, the Keystone pipeline, nuclear proliferation, hydraulic fracturing or “fracking,” fisheries depletion, species extinction and other important environmental concerns.  What distinguishes the green movement today from the earlier conservation movement is its emphasis on science and research. Speaking in spiritual tones and using religious metaphors, early environmentalists like Muir and Thoreau celebrated nature for its profound impact on man’s emotions and our souls. When Hetch Hetchy Valley in California was threatened by a dam, Muir exclaimed, “Dam Hetch Hetchy! As well dam for water-tanks the people’s cathedrals and churches, for no holier temple has ever been consecrated by the heart of man.”  Now, however, we are far more likely to call upon scientific data and empirical research to buttress arguments in favor of wilderness preservation, or against polluting industries. Politicians cite the work of polar researchers and use computerized climate models  o battle global warming, and medical researchers rely on public health statistics to argue against mercury pollution. Whether these arguments succeed or fail, however, still depends on the vision, the passion and the commitment of the people who make up the green movement

Insects’ lives are very short and they have many enemies but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look “inedible” by imitating plants is a way frequently used by insects to survive. Mammals rarely imitate plants, but many fish and invertebrates do. The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called “measuring worm” or “inchworm”. It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind fed forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed. Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection: they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live. Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the plants that they resemble

Few political and social issues generate as much passion and controversy as immigration. One of the most prominent concerns among anti-immigration campaigners is the idea that immigration breaks down the host society’s cultural traditions and harms its cultural identity. Central to these debates is what academics call “acculturation”. This term refers to behavioural or psychological changes in immigrants or their descendants that follow migration. They are typically changes that make behaviour or ways of thinking more similar to members of the adopted society. Recent studies typically measure behavioural or psychological traits in first generation migrants, second generation migrants, and non-migrants who have been living in the host area for several generations. The evidence suggests that acculturation is common, but generational. While first generation migrants typically retain the values of their society of origin, later generations shift about 50% of the way from their parents’ values towards nonmigrant values. This even occurs in communities that form large, cohesive minorities. Migration with no acculturation breaks down distinct host cultures. This is the scenario envisioned by anti-immigration campaigners. Even a little migration, without acculturation, soon creates a homogeneous worldwide blend of the cultural traits that were originally unique to different societies. But adding just a small amount of acculturation to the simulations could preserve cultural differences. For example, even for relatively high migration rates where ten per cent of the society migrates in each time period, just a 20% probability of acculturation is needed to maintain distinct cultural variation between societies. This suggests that the 50% acculturation level observed in the real-world is strong enough to preserve distinct cultures.  These results held for both “neutral” traits such as dress or dance, and for costly cooperative traits, such as building bridges or paying taxes, where individuals pay initial costs to benefit the entire society. Much concern over immigration centres on the latter – that immigrants take benefits without paying costs. There were, however, levels of migration at which no level of acculturation could preserve cultural traditions. When 50% or more of the societies migrate, then distinct traditions cannot be maintained. While this exceeds modern levels of migration, we might think of historical cases of colonisationas examples where high levels of migration broke down traditions. Whatever future research finds, it would surely be better if immigration policy and media coverage of immigration, were better informed by the available evidence concerning migrant acculturation

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.
