Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators. 
Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars. 
Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam. CSP power plants can store large amount of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also burn natural gas to provide the heat that is used to turn water into steam. 
Sunlight provides the energy needed to grow plants and make large amount of environmentally friendly heat and electricity. Solar energy can provide power today and for a long time in the future.

Stars have been significant features in the design of many United States coins and their number has varied from one to forty-eight stars. Most of the coins issued from about 1799 to the early years of the twentieth century bore thirteen stars representing the thirteen original colonies. Curiously enough, the first American silver coins, issued in 1794, had fifteen stars because by that time Vermont and Kentucky has joined the Union. At that time it was apparently the intention of mint officials to add a star for each new state. Following the admission of Tennessee in 1796, for example, some varieties of half dimes, dimes, and half-dollars were produced with sixteen starts. As more states were admitted to the Union, however, it quickly became apparent that this scheme would not prove practical and the coins from A798 on were issued with only thirteen stars-one for each ofthe original colonies. Due to an error at the mint, one variety of the A828 half cent was issued with only twelve stars. There is also a variety of the large cent with only A2 stars, but this is the result of a die breakand is not a true error.

The expression “Curiously enough” is used because the author finds it strange that _______ .

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 early civilizations, citizens were educated informally, usually within the family unit. Education meant simply learning to live. As civilizations became more complex, however, education became more formal, structured and comprehensive. Initial efforts of the ancient Chinese and Greek societies concentrated solely on the education of males. The post-Babylonian Jews and Plato were exceptions to this pattern. Plato was apparently the first significant advocate of the equality of the sexes. Women, in his ideal state, would have the same rights and duties and the same educational opportunities as men. This aspect of Platonic philosophy, however, had little or no effect on education for many centuries, and the concept of a liberal education for men only, which had been espoused by Aristotle, prevailed.

   In ancient Rome, the availability of an education was gradually extended to women, but they were taught separately from men. The early Christians and medieval Europeans continued this trend, and singlesex schools for the privileged classes prevailed through the Reformation period. Gradually, however, education for women on a separate but equal basis to that provided for men was becoming a clear responsibility of society. Martin Luther appealed for civil support of schools for all children. At the Council of Trent in the 16th century, the Roman Catholic Church encouraged the establishment of free primary schools for children of all classes. The concept of universal primary education, regardless of sex, had been born, but it was still in the realm of the single-sex school.

   In the late 19th and early 20th centuries, co-education became a more widely applied principle of educational philosophy. In Britain, Germany, and the Soviet Union the education of boys and girls in the same classes became an accepted practice. Since World War II, Japan and the Scandinavian countries have also adopted relatively universal co-educational systems. The greatest negative reaction to coeducation has been felt in the teaching systems of the Latin countries, where the sexes have usually been separated at both primary and secondary levels, according to local conditions.

   A number of studies have indicated that girls seem to perform better overall and in science in particular in single-sex classes: during the adolescent years, pressure to conform to stereotypical female gender roles may disadvantage girls in traditionally male subjects, making them reluctant to volunteer for experimental work while taking part in lessons. In Britain, academic league tables point to high standards achieved in girls' schools. Some educationalists therefore suggest segregation of the sexes as a good thing, particularly in certain areas, and a number of schools are experimenting with the idea.

The word "espouse” is contextually closest in meaning to "_______"

Question‌ ‌18‌‌ ‌‌(TH):‌ ‌...................

As many as one thousand years ago in the Southwest, the Hopi and Zuni Indians of North America were building with adobe-sun-baked brick plastered with mud.  Their homes looked remarkably like modern apartment houses. Some were four stories high and contained quarters for perhaps a thousand people, along with storerooms for grain and other goods. These buildings were usually put up against cliffs, both to make construction easier and for defense against enemies. They were really villages in themselves, as later Spanish explorers must have realised since they called them "pueblos", which is Spanish for towns. The people of the pueblos raised what are called "the three sisters" - corn,  beans, and squash. They made excellent pottery and wove marvelous baskets, some so fine that they could hold water. The Southwest has always been a dry country, where water is scarce. The Hopi and Zuni brought water from streams to their fields and gardens through irrigation ditches. Water was so important that it played a major role in their religion. They developed elaborate ceremonies and religious rituals to bring rain. The way of life of less - settled groups was simpler and more strongly influenced by nature.
Small tribes such as the Shoshone and Ute wandered the dry and mountainous lands between the Rocky Mountains and the Pacific Ocean. They gathered seeds and hunted small animals such as rabbits and snakes.
In the Far North, the ancestors of today's Inuit hunted seals, walruses, and the great whales. They lived right on the frozen season shelters called igloos built of blocks of packed snow. When summer came, they fished for salmon and hunted the lordly caribou.
The Cheyenne, Pawnee and Sioux tribes, known as the Plains Indians, lived on the grasslands between the Rocky Mountains and the Mississippi River. They hunted bison, commonly called the buffalo. Its meat was the chief food of these tribes, and its hide was used to make their clothing and the covering of their tents and tepees.

It can be inferred from the passage that the dwellings of the Hopi and Zuni were.....................

Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man’s inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.
Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist- skinned, water-loving animals can exist there. Few large animals are found. The giants of the North American desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift-footed running and leaping creatures than the tangled forest. Its population is largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated.
Having adapted to their austere environment, they are as healthy as animals anywhere else in the word. The secret of their adjustment lies in the combination of behavior and physiology. None could survive if, like mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun- baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.

According to the passage, creatures in the desert________.

Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology.
Deep inside the brain there is a "clock" that governs every aspect of the body's functioning: sleep and wake cycles, levels of alertness, performance, mood, hormone levels, digestion, body temperature and so on. It regulates all of these functions on a 24-hour basis and is called the circadian clock (from the Latin, circa "about" + dies "day"). This body clock programmes us to be sleepy twice a day, between 3-5 a.m and again between 3-5 p.m.
Afternoon tea and siesta times are all cultural responses to our natural biological sleepiness in the afternoon.
One of the major causes of the travelers' malady known as jet lag is the non-alignment of a person's internal body clock with clocks in the external world. Crossing different time zones confuses the circadian clock, which then has to adjust to the new time and patterns of light and activity. To make matters more complex, not all internal body functions adjust at the same rate. So your sleep/wake may adjust to a new time zone at one rate, while your temperature adjusts at a different pace. Your digestion may be on a different schedule altogether.
Though we live in a 24-hour day, the natural tendency of the body clock is to extend our day beyond 24 hours. It is contrary to our biological programming to shrink our day. That is why traveling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quantity and quality than eastward flights.
When flying west, you are "extending" your day, thus traveling in the natural direction of your internal clock. Flying eastward will involve "shrinking" or reducing your day and is in direct opposition to your internal clock's natural tendency. One of the more common complaints of travelers is that their sleep becomes disrupted. There are many reasons for this: Changing time zones and schedules, changing light and activity levels, trying to sleep when your body clock is programmed to be awake, disruption of the internal circadian clock and working longer hours.
Sleep loss, jet lag and fatigue can seriously affect our ability to function well. Judgment and decision-making can be reduced by 50%, attention by 75 percent, memory by 20 percent and communication by 30 percent.
It is often suggested that you adjust your watch as soon as you board a plane, supposedly to try to help you adjust to your destination's schedule as soon as you arrive. But it can take the body clock several days to several weeks to fully adjust to a new time zone.

According to the author, which of the following reasons disrupt travelers' sleep?

Read the passage below and choose one correct answer for each question.

It has been thought that women are the second class in citizen, and men are the first. There is not a real equality of opportunity for men and women. Years ago, people were living in a man-dominated society. Women had to obey their husbands and fathers absolutely. Women's place was in the kitchen and women's work was housework. In many places, women were not even allowed to go to school. Women had no rights, even the right to choose husband for themselves. Men usually occupied high positions in society so they thought they were more intelligent than women. Men often considered women as their property. Sometimes, they were mistreated by their husbands and suffered the problem as a fate. Many parents did not even want to daughters.

Despite the progress, there remain outdated beliefs about women's roles, traditionally passed down from generation to generation. Men are commonly seen as the strong bodies, bread-winners in the family and key leaders in society, while women are restricted to being housewives and child bearing and care, and housework such as washing and cooking.

According to social surveys, many women in the 21st century still have to work over 12 hours a day including working in offices and doing countless household chores without any help from their husbands. In some regions, the labor of women is not recognized despite the hardships they endure to support the whole family. Moreover, women are the direct victims of family violence, especially in rural areas.

Thanks to the women's liberation movement, nowadays women have proved that they are equal to men in every aspect. An average woman has weaker muscles than an average man but she may be as intelligent as he is. Women can do everything that men can, and women can do one thing that no man can: they produce children.

Which is not women's role in the former days?

Just as optical fibers have transformed communication, they are also revolutionizing medicine. These ultrathin, flexible fibers have opened a window into the living tissues of the body. By inserting optical fibers through natural openings or small incisions and threading  them along the body's established pathways, physicians can look into the lungs, intestines,  heart and other areas that were formerly inaccessible to   them.
The basic fiber-optics system is called fiberscope, which consists of  two  bundles  of fibers. One, the illuminating bundle, carries light to the tissues. Is is coupled to  a  high- intensity light source. Light enters the cores of the high-purity silicon glass and travels along the fibers. A lens at the end of the bundle collects the light and  focuses  it into the other  bundle, the imaging bundle. Each fiber in the bundle transmits only a tiny fraction of the total image. The reconstructed image can be viewed through an eyepiece or displayed on a television screen.
During the last five years, improved methods of fabricating optical fibers have led to a reduction in fiberscope diameter and an increase in the number of fibers, which in turn has increased resolution. Optical fibers can also be used to deliver laser light. By use of laser beams, physicians can perform surgery inside the body, sometimes eliminating the need for invasive procedures in which healthy tissue must be cut through to reach the site of disease. Many of these procedures do not require anesthesia and can be performed in a physician's office. These techniques have reduced the risk and the cost of medical care.

According to the passage, what is the purpose of the illuminating bundle in a fiberscope?

In addition to their military role, the forts of the nineteenth century provided numerous other benefits for the American West. The establishment of these posts opened new roads and provided for the protection of daring adventurers and expeditions as well as established settlers. Forts also served as bases where enterprising entrepreneurs could bring commerce to the West, providing supplies and refreshments to soldiers as well as to pioneers. Posts like Fort Laramie provided supplies for wagon trains traveling the natural highways toward new frontiers. Some posts became stations for the pony express; still others, such as Fort Davis, were stagecoach stops for weary travelers. All of these functions, of course, suggest that the contributions of the forts to the civilization and development of the West extended beyond patrol duty.
 Through the establishment of military posts, yet other contributions were made to the development of western culture. Many posts maintained libraries or reading rooms, and some – for example, Fort Davis – had schools. Post chapels provided a setting for religious services and weddings. Throughout the wilderness, post bands provided entertainment and boosted morale. During the last part of the nineteenth century, to reduce expenses, gardening was encouraged at the forts, thus making experimental agriculture another activity of the military. The military stationed at the various forts also played a role in civilian life by assisting in maintaining order, and civilian officials often called on the army for protection.
 Certainly, among other significant contributions the army made to the improvement of the conditions of life was the investigation of the relationships among health, climate, and architecture. From the earliest colonial times throughout the nineteenth century, disease ranked as the foremost problem in defense. It slowed construction of forts and inhibited their military functions. Official documents from many regions contained innumerable reports of sickness that virtually incapacitated entire garrisons. In response to the problems, detailed observations of architecture and climate and their relationships to the frequency of the occurrence of various diseases were recorded at various posts across the nation by military surgeons.

Which of the following would a traveler be LEAST likely to obtain at Fort Laramie?

In the fourth paragraph, the word “which” refers to _______ 

A pioneering study by Donald Appleyard made the astounding discovery that a sudden increase in the volume of traffic through an area affects people in the way that a sudden increase in crime does. Appleyard observed this by finding three blocks of houses in San Francisco that looked much alike and had the same kind of middle-class and working-class residents, with approximately the same ethnic mix. The difference was that only 2,000 cars a day ran down Octavia Street (LIGHT street, in Appleyard’s terminology) while Gough Street (MEDIUM street) was used by 8,000 cars daily, and Franklin Street (HEAVY street) had around 16,000 cars a day. Franklin Street often had as many cars in an hour as Octavia had in a day.
Heavy traffic brought with it danger, noise, fumes and soot, directly, and trash secondarily. That is, the cars didn’t bring in much trash, but when trash accumulated, residents seldom picked it up. The cars, Appleyard determined, reduced the amount of territory residents felt responsible for. Noise was a constant intrusion into their homes. Many Franklin Street residents covered their doors and windows and spent most of their time in the rear of their houses. Most families with children had already left.
Conditions on Octavia Street were much different. Residents picked up trash. They sat on their front steps and chatted with neighbors. They had three times as many friends and twice as many acquaintances as the people on Franklin.
On Gough Street, residents said that the old feeling of community was disappearing as traffic increaseD. People were becoming more and more preoccupied with their own lives. A number of families had recently moved and more were considering. Those who were staying expressed deep regret at the destruction of their community.

In what order does the author present detailed discussions of the three streets?

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 growth of cities, the construction of hundreds of new factories, and the spread of railroads in the United Stases before 1850 had increased the need for better illumination. But the lighting in  American homes had improved very little over that of ancient times. Through the colonial period,  homes were lit with tallow candles or with a lamp of the kind used in ancient Rome- a dish of fish oil or  other animal or vegetable oil in which a twisted rag served as a wick. Some people used lard, but they  had to heat charcoal underneath to keep it soft and burnable. The sperm whale provided superior  burning oil, but this was expensive. In 1830 a new substance called "camphene" was patented, and  it proved to be an remained expensive, had an unpleasant odor, and also was dangerously explosive.
Between 1830 and 1850 it seemed that the only hope for cheaper illumination in the United  States was the wider use of gas. In the 1840s American gas manufacturers adopted improved British  techniques for producing illuminating gas from coal. But the expense of piping gas to the consumer  remained so high that until mid- century gas lighting was feasible only in urban areas, and only for  public buildings for the wealthy. In 1854 a Canadian doctor, Abraham Gesner, patented a process for  distilling a pitch like mineral found in New Brunswick and Nova Scotia that produced illuminating  gas and an oil that he called "kerosene" (from "keros", the Greek word for wax, and "ene" because  it resembled camphene). Kerosene, though cheaper than camphene, had an unpleasant odor, and  Gesner never made his fortune from it. But Gesner had aroused a new hope for making illuminating oil from a product coming out of North American mines.

Which of the following is NOT mentioned as a reason why better lighting had become necessary by the mid“ nineteenth century?

Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction. 
Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. 
The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space. In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail.

The author mentions the trail pheromone of the leafcutter ant in line 8 to point out

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 goal of Internet-based encyclopedia Wikipedia (www.wikipedia.org) is to give everyone on the planet access to information. Like other encyclopedias, Wikipedia contains lots of information: more than 2.5 million articles in 200 different languages covering just about every subject. Unlike other encyclopedias, however, Wikipedia is not written by experts, but by ordinary people. These writers are not paid and their names are not published. They contribute to Wikipedia simply because they want to share their knowledge.
Encyclopedias began in ancient times as collections of writings about all aspects of human knowledge. The word itself comes from ancient Greek, and means "a complete general education". Real popularity for encyclopedias came in the nineteenth century in Europe and the United States, with the publication of encyclopedias written for ordinary readers. With the invention of the CD- ROM, the same amount of information could be put on a few computer discs. Then with the Internet, it became possible to create an online encyclopedia that could be constantly updated, like Microsoft's Encarta. However, even Internet-based encyclopedias like Encarta were written by paid experts. At first, Wikipedia, the brainchild of Jimmy Wales, a businessman in Chicago, was not so different from these. In 2001, he had the idea for an Internet-based encyclopedia that would provide information quickly and easily to everyone. Furthermore, that information would be available free, unlike other Internet encyclopedias at that time.
But Wales, like everyone else, believed that people with special knowledge were needed to write the articles, and so he began by hiring experts. He soon changed his approach, however, as it took them a long time to finish their work. He decided to open up the encyclopedia in a radical new way, so that everyone would have access not only to the information, but also to the process of putting this information online. To do this, he used what is known as "Wiki" software (from the Hawaiian word for "fast"), which allows users to create or alter content on web page. The system is very simple: When you open the web site, you can simply search for information or you can log on to become a writer or editor of articles. If you find an article that interests you - about your hometown, for example - you can correct it or expand it. This process goes on until no one is interested in making any more changes.

Food‌ ‌insecurity‌ ‌plays‌ ‌an‌ ‌important‌ ‌role‌ ‌too.‌ ‌Nepalese‌ ‌families‌ ‌that‌ ‌do‌ ‌not‌ ‌have‌ ‌enough‌ ‌food‌ ‌to‌ ‌eat‌ ‌are‌ ‌more‌ ‌likely‌ ‌to‌ ‌marry‌ ‌their‌ ‌daughters‌ ‌at‌ ‌a‌ ‌young‌ ‌age‌ ‌to‌ ‌decrease‌ ‌the‌ ‌financial‌ ‌‌burden‌.‌ ‌One‌ ‌study‌ ‌shows‌ ‌that‌ ‌91%‌ ‌of‌ ‌people‌ ‌who‌ ‌had‌ ‌secure‌ ‌access‌ ‌to‌ ‌food‌ ‌married‌ ‌over‌ ‌the‌ ‌age‌ ‌of‌ ‌19.‌ ‌
Dowry‌ ‌is‌ ‌also‌ ‌a‌ ‌common‌ ‌practice‌ ‌in‌ ‌many‌ ‌communities.‌ ‌Parents‌ ‌marry‌ ‌their‌ ‌daughters‌ ‌as‌ ‌soon‌ ‌as‌ ‌possible‌ ‌because‌ ‌the‌ ‌money‌ ‌they‌ ‌have‌ ‌to‌ ‌pay‌ ‌for‌ ‌the‌ ‌groom's‌ ‌family‌ ‌is‌ ‌higher‌ ‌if‌ ‌their‌ ‌daughter‌ ‌is‌ ‌older.‌ ‌Since‌ ‌2010,‌ ‌the‌ ‌legal‌ ‌age‌ ‌of‌ ‌marriage‌ ‌is‌ ‌20‌ ‌for‌ ‌both‌ ‌men‌ ‌and‌ ‌women,‌ ‌or‌ ‌18‌ ‌with‌ ‌parental‌ ‌consent,‌ ‌according‌ ‌to‌ ‌the‌ ‌Nepalese‌ ‌Country‌ ‌Code.‌ ‌
The‌ ‌law‌ ‌states‌ ‌that‌ ‌punishment‌ ‌for‌ ‌child‌ ‌marriage‌ ‌is‌ ‌‌imprisonment‌ ‌for‌ ‌up‌ ‌to‌ ‌three‌ ‌years‌ ‌and‌ ‌a‌ ‌fine‌ ‌of‌ ‌up‌ ‌to‌ ‌10,000‌ ‌rupees‌ ‌(£102).‌ ‌But‌ ‌reports‌ ‌suggest‌ ‌that‌ ‌this‌ ‌law‌ ‌is‌ ‌rarely‌ ‌applied.‌ ‌There‌ ‌has‌ ‌been‌ ‌quite‌ ‌a‌ ‌lot‌ ‌of‌ ‌progress‌ ‌in‌ ‌Nepal‌ ‌over‌ ‌the‌ ‌past‌ ‌3‌ ‌years‌ ‌with‌ ‌a‌ ‌clear‌ ‌government‌ ‌commitment‌ ‌to‌ ‌ending‌ ‌child‌ ‌marriage‌ ‌and‌ ‌civil‌ ‌society‌ ‌cooperation.‌ ‌The‌ ‌Ministry‌ ‌of‌ ‌Women,‌ ‌Children‌ ‌and‌ ‌Social‌ ‌Welfare‌ ‌is‌ ‌currently‌ ‌developing‌ ‌Nepal's‌ ‌first‌ ‌national‌ ‌strategy‌ ‌on‌ ‌child‌ ‌marriage‌ ‌in‌ ‌collaboration‌ ‌with‌ ‌UNICEF‌ ‌Nepal‌ ‌and‌ ‌Girls‌ ‌Not‌ ‌Brides‌ ‌Nepal.‌ ‌However,‌ ‌the‌ ‌post-earthquake‌ ‌and‌ ‌post-fuel‌ ‌crisis‌ ‌environment‌ ‌has‌ ‌meant‌ ‌progress‌ ‌is‌ ‌slow‌ ‌and‌ ‌the‌ ‌national‌ ‌strategy‌ ‌has‌ ‌been‌ ‌delayed.‌ ‌

The‌ ‌word‌ ‌“‌imprisonment‌”‌ ‌in‌ ‌the‌ ‌last‌ ‌paragraph‌ ‌could‌ ‌be‌ ‌best‌ ‌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 questions.

   Over the past 600 years, English has grown from a language of few speakers to become the dominant language of international communication. English as we know it today emerged around 1350, after having incorporated many elements of French that were introduced following the Norman invasion of 1066. Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as two centuries, English began to spread around the globe as a result of exploration, trade (including slave trade), colonization, and missionary work. Thus, small enclaves of English speakers became established and grew in various parts of the world. As these communities proliferated, English gradually became the primary language of international business, banking and diplomacy.

   Currently, about 80 percent of the information stored on computer systems worldwide is English. Two thirds of the world’s science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and over half of these are nonnative speakers, constituting the largest number of non-native users than any other language in the world..
