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. 
      To quote CREST founder Dr. Martha Honey, we earnestly believe that ecotourism is “simply a better way to travel.” Here’s a look at how this transformational approach to travel benefits conservation, increases cross-cultural understanding, and ultimately turns travelers into environmental advocates:
       To see how ecotourism benefits nature and wildlife, let’s look at endangered species such as African Elephants. Ivory from Elephant tusks is worth $1500 a pound on the black market, which has led to a dramatic increase in poaching. But Elephants are worth 76 times more alive than dead. When you consider the revenue from wildlife photography tours, luxury safari camps, and other ecotourism offerings, a single Elephant is worth $1.3 million over the course of its lifetime! Ecotourism offers a long-term alternative to exploitation, generating sustainable revenue and ensuring better overall health of the ecosystem.
       Nature reserves and national parks help prevent deforestation and pollution, while also protecting the habitat of endemic species. The revenue that ecotourism provides can help replace profits from exploitative practices such as mining or slash ‘n’ burn agriculture. It can also help ensure the long-term financial viability of the area. Naturalist guides also help travelers understand the value of a pristine ecosystem, and teach them about the importance of conservation. This ultimately help to create a more mindful and conscious legion of travelers.
      When managed properly, ecotourism can offer locals alternative revenue streams. In wildlife-rich countries such as Rwanda, former poachers are often employed as guides or trackers, capitalizing on their knowledge of the animals and their habitat. In Costa Rica, unemployment has fallen to less than 10% since the country started building its ecotourism infrastructure in the 1970s. Involving local communities in tourism management empowers them by ensuring that more revenue is reinvested locally. Ecotourism also offers indigenous peoples an opportunity to remain on ancestral land, conserve it, and preserve traditional culture.
      Sure, being a responsible traveler takes a greater level of commitment to being conscious and mindful of the impact we have on the destinations we visit. But ecotourism also offers us incredible, transformative experiences, allowing us to develop closer personal relationships to the nature, wildlife, and local people we encounter during our adventures. Learning about ecotourism can permanently change your understanding of mankind’s role in our planetary ecosystem. And once you’ve had that sort of travel experience, you’ll never want to travel the traditional way again.

The word “pristine” in paragraph 3 most likely means _______.

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.

   A rather surprising geographical feature of Antarctica is that a huge freshwater lake, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warmed by geothermal heat from the earth’s core. The thick glacier above Lake Vostok actually insulates it from the frigid temperatures on the surface.

   The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

   The discovery of such a huge freshwater lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas. The downside of the discovery, however, lies in the difficulty of conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated samples from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

The word “microbes” in paragraph 3 could best be replaced by which of the following?

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. 
No matter how much you’ve trained, performance anxiety before or during a competition may occur, hindering the results of your match. 
While you can tell yourself to stay calm prior to a competition, managing performance anxiety may not be as simple as. Research has shown that strategies such as meditation and guided imagery are great places to start; both require your brain to rehearse what you will do during your competition. Your imagination holds much more power than you may expect, helping you focus on how to beat your opponent, instead of other factors that contribute to your anxiety. Adequate preparation also plays a large role.
To master the mental game, it takes time. Starting one month before your competition, consider sitting in solitude in a comfortable position for 15 minutes each day. Focus first on breathing in and out deeply. Then, begin to imagine competition situations and visualize yourself in a fight with your competitor. Be mindful of your anxiety and return your focus to breathing if you feel yourself tense up. Sometimes, you may find yourself thinking self-deprecating or negative thoughts, at which point you should consciously replace any negative self-talk with positive self-talk. During these visualizations, also be sure to think about your posture and form and create cues — mental and verbal — that will help you review and correct your technique.
Pre-competition jitters are completely normal and it’s important to acknowledge that. Accepting that this excitement and/or nervousness is normal will help your body also understand that what you are experiencing is not fear, but perhaps part of your adrenaline response to competition. With more experience, mindful visualization and mental/physical preparation can help you manage and overcome performance anxiety.

The word “hindering” in paragraph 1 is closest in meaning to ______.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

   In developing countries, where three fourths of the world's population live, sixty percent of the people who can’t read and write are women. Being illiterate doesn’t mean they are not intelligent. It does mean it is difficult for them to change their lives. They produce more than half of the food. In Africa eighty percent of all agricultural work is done by women. There are many programs to help poor countries develop their agriculture. However, for years, these programs provided money and training for men.

   In parts of Africa, this is a typical day for a village woman. At 4:45 a.m, she gets up, washes and eats. It takes her a half hour to walk to the fields, and she works there until 3:00 p.m. She collects firewood and gets home at 4:00. She spends the next hour and a half preparing food to cook. Then she collects water for another hour. From 6:30 to 8:30 she cooks. After dinner, she spends an hour washing the dishes and her children. She goes to bed at 9:30 p.m.

   International organizations and programs run by developed nations are starting to help women, as well as men, improve their agricultural production. Governments have already passed some laws affecting women because of the UN Decade for Women. The UN report will affect the changes now happening in the family and society.

The 24th SEA Games was held from 6th to 15th December, 2007 in three provinces in Thailand, namely Nakhon Ratchsima, Bangkok, and Chon Buri. In fact, the 2007 SEA Games was to be hosted by Singapore, but Singapore gave up the chance, as its new national sports stadium is under construction and will not be completed in time for the next SEA Games. Thailand was then asked by The SEA Games Federation to host this regional sport event in place of Singapore.
The SEA Games takes place every two years, with 11 countries in Southeast Asia participating. Each member country, in alphabetical order, takes turn hosting this event. Let’s look at the number of sports and gold medals in The SEA Games in recent years. The 21st SEA Games, hosted by Malaysia in 2001, had 32 sports with 391 gold medals. There were 32 sports with 439 gold medals in The 22nd SEA Games, held in Vietnam in 2003. The 23rd SEA Games, in The Philippines in 2005, had 40 sports with 439 gold medals.
The 24th SEA Games in Thailand this year, featuring 43 sports and 485 gold medals, had the highest number of sports and gold medals in The Asian Games and The Olympic Games. So The SEA Games is regarded as the largest regional sporting event in the world in terms of number of sports and medals

How often does the SEA Games take place? Every ___________.

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.

   Thanksgiving is celebrated in the US on the fourth Thursday in November. For many Americans it is the most important holiday apart from Christmas. Schools, offices and most businesses close for Thanksgiving, and many people make the whole weekend a vacation.

   Thanksgiving is associated with the time when Europeans first came to North America. In 1620 the ship the Mayflowers arrived, bringing about 150 people who today are usually called Pilgrims. They arrived at the beginning of a very hard winter and could not find enough to eat, so many of them died. But in the following summer Native Americans showed them what foods were safe to eat, so that they could save food for the next winter. They held a big celebration to thank God and the Native Americans for the fact that they had survived.

   Today people celebrate Thanksgiving to remember these early days. The most important part of the celebration is a traditional dinner with foods that come from North America. The meal includes turkey, sweet potatoes (also called yams) and cranberries, which are made into a kind of sauce or jelly. The turkey is filled with stuffing or dressing, and many families have their own special recipe. Dessert is pumpkin made into a pie.

   On Thanksgiving there are special television programs and sports events. In New York there is the Macy's Thanksgiving Day Parade, when a long line of people wearing fancy costumes march through the streets with large balloons in the shape of imaginary characters. Thanksgiving is considered the beginning of the Christmas period, and the next day many people go out to shop for Christmas presents.

In the second paragraph, the pronoun "them" refers to which of the following?

Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. One adaptation is to be light in color,  and to reflect rather than absorb the Sun's rays. Desert mammals also depart from the normal mammalian practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside the body, which would involve the expenditure of water and energy,  desert mammals allow their temperatures to rise to what would normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in Grant's gazelles. The overheated body then cools down during the cold desert night, and indeed the temperature may fall unusually low by dawn,  as low as 34 degrees Celsius in the camel. This is an advantage since the heat of the first few hours of daylight is absorbed in warming up the body, and an excessive buildup of heat does not begin until well into the day.

Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight as water without harm to itself, whereas human beings die after losing only 12 to 13 percent of their body weight. An equally important adaptation is the ability to replenish this water loss at one drink. Desert animals can drink prodigious volumes in a short time, and camels have been known to imbibe over 100 liters in a few minutes. A very dehydrated person, on the other hand, cannot drink enough water to rehydrate at one session, because the human stomach is not sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the further ability to feed normally when extremely dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst.

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 our connected globalized world, the languages which dominate communications and business, Mandarin, Hindi, English, Spanish and Russian amongst others, are placing small languages spoken in remote places under increasing pressure. Fewer and fewer people speak languages such as Liki, Taushiro and Dumi as their children shift away from the language of their ancestors towards languages which promise education, success and the chance of a better life. While to many parents, this may appear a reasonable choice, giving their offspring the opportunity to achieve the sort of prosperity they see on television, the children themselves often lose touch with their roots. However, in many places the more reasonable option of bilingualism, where children learn to speak both a local and a national language, is being promoted. This gives hope that many endangered languages will survive, allowing people to combine their links to local tradition with access to wider world culture. 
While individuals are free to choose if they wish to speak a minority language, national governments should be under no obligation to provide education in an economically unproductive language, especially in times of budget constraints. It is generally accepted that national languages unite and help to create wealth while minority regional languages divide. Furthermore, governments have a duty to ensure that young people can fulfil their full potential, meaning that state education must provide them with the ability to speak and work in their national language and so equip them to participate responsibly in national affairs. People whose language competence does not extend beyond the use of a regional tongue have limited prospects. This means that while many people may feel a sentimental attachment to their local language, their government’s position should be one of benign neglect, allowing people to speak the language, but not acting to prevent its eventual disappearance.
Many PhD students studying minority languages lack the resources to develop their language skills, with the result that they have to rely on interpreters and translators to communicate with speakers of the language they are studying. This has a detrimental effect on the quality of their research. At the same time, they have to struggle against the frequently expressed opinion that minority languages serve no useful purpose and should be allowed to die a natural death. Such a view fails to take into account the fact that a unique body of knowledge and culture, built up over thousands of years, is contained in a language and that language extinction and species extinction are different facets of the same process. They are part of an impending global catastrophe which is beginning to look unavoidable.

What can be inferred from the sentence “their government’s position should be one of benign neglect” in paragraph 2?

Which statement is NOT true according to the passage?

Almost as soon as World War II ended, the debate began over who had actually done the  most on the Allied side to ensure the defeat of the Axis powers. The Russians only needed to point to their twenty million plus war dead to justify their rights in Eastern Europe and their new  position as a great power on the world stage. Yet, Americans could also claim that they had done as much, if not more, as the Russians to defeat the Axis enemy. In hindsight, it is obvious that  despite its greater number of dead, the Russian effort ranks second place to the American. In  particular, the American effort seems greater in light of three crucial points: it was fighting at  extreme distances from its home territory; it simultaneously fought three different enemies on a multitude of complex fronts with air, naval, land forces; and finally, it supplied many other fighting  forces, including the Russians, with massive amounts ofmaterial. 

The main fronts of World War II were in North Africa, Italy, Western and Eastern Europe, the Pacific Ocean, China, and India. The United States military forces fought on or supported  every front, all of which were at extreme distances from the continental United States. A great logistical effort required to support both its own forces and those of many other nations. Above all,  supply ships were essential because without the supply ships, all would have been in vain.  Keeping the world's sea lanes free was one of the great accomplishments of the United States  Navy and her allies, especially the British and Canadians. This allowed ships to traverse great  distances and bring American and other Allied fighting forces to face the Axis powers. The Russians, on the other hand, were  fighting in their own country for much of the war and were close to their supply lines. They fought on one continuous font and did not have to travel far to meet the enemy.

The United States fought all three great Axis powers during the war: Germany, Japan, and  Italy. While it cannot be denied that the Russian did the lion's share of the fighting against  Germany and the lesser Axis powers of Finland, Hungary, Romania, and Bulgaria for a longer  time, it was not until the last days of the war that Russia attacked Japan. As for the Italians, the  Russians only met the reluctant few whom Hitler managed to coerce for his Russian campaign. Another area to take into consideration is the strategic bombing campaign that the Americans and  British waged against German industry, something that the Russians did not take part in at all.  Finally, with the exception of the Baltic Sea, the Russian navy played a very minor role in the war  compared to American's navy. Despite significant aid from the British, Australians, and New Zealanders, the Americans bore the brute of the Pacific fighting. 

The Chinese tied down a massive number of Japanese troops on the Asian mainland, but  they were supplied almost exclusively by the United States. American arms, support equipment,  food, and clothing went to the four corners of the world during the war even before American officially entered it in 1941. Indeed, the Russian Red Army rode into Eastern Europe on the wheels  of over 300,000 American trucks, fed itself on a diet of American canned ham, and wore 

American boots. Coupled with all this were billion-dollar loans with generous terms of interest, which America gave to its allies. American was the only Allied nation that did not need to borrow  any money during the war.

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 mineral particles found in soil range in size from microscopic clay particles to large boulders. The most abundant particles - sand, silt, and clay - are the focus of examination in studies of soil texture. Texture is the term used to describe the line composite sizes of particles in a soil sample, typically several representative handfuls . To measure soil texture, the sand, silt, and clay particles are sorted out by size and weight. The weights of each size are then expressed as a percentage of the sample weight.

   In the field, soil texture can be estimated by extracting a handful of sod and squeezing the damp soil into three basic shapes; (1) cast, a lump formed by squeezing a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil between the palms; and (3) ribbon, a flatfish shape formed by squeezing a small sample between the thumb and index finger. The behavioral characteristics of the soil when molded into each of these shapes, if they can be formed at all, provides the basis for a general textural classification. The behavior of the soil in the hand test is determined by the amount of clay in the sample. Clay particles are highly cohesive, and when dampened , behave as a plastic. Therefore the higher the clay content in a sample, the more refined and durable the shapes into which it can be molded.

   Another method of determining soil texture involves the use of devices called sediment sieves, screens built with a specified mesh size. When the soil is filtered through a group of sieves, each with a different mesh size, the particles become grouped in corresponding size categories. Each category can be weighed to make a textural determination. Although sieves work well for silt, sand, and larger particles, they are not appropriate for clay particles. Clay is far too small to sieve accurately; therefore, in soils with a high proportion of clay, the fine particles are measured on the basis of their settling velocity when suspended in water. Since clays settle so slowly, they are easily segregated from sand and silt. The water can be drawn off and evaporated, leaving a residue of clay, which can be weighed.

It can be inferred from the passage that a soil sample with little or no clay in it ______.

   Mandatory volunteering made many members of Maryland's high school class of 97 grumble with indignation. They didn't like a new requirement that made them take part in the school's community service program. Future seniors, however, probably won't be as resistant now that the program has broken in. Some, like John Maloney, already have completed their required hours of approved community service. The Bowie High School sophomore earned his hours in eighth grade by volunteering two nights a week at the Larkin-Chase Nursing and Restorative Center in Bowie.He played shuffle board, cards, and other games with the senior citizens. He also helped plan parties for them and visited their rooms to keep them company.

   John, fifteen, is not finished volunteering. Once a week he videotapes animals at the Prince George's County animal shelter in Forestville. His footage is shown on the Bowie public access television channel in hopes of finding homes for the animals. "Volunteering is better than just sitting around," says John, "and I like animals; I don't want to see them put to sleep." He's not the only volunteer in his family. His sister, Melissa, an eighth grader, has completed her hours also volunteering at Larkin-Chase.

   "It is a good idea to have kids go out into the community, but it's frustrating to have to write essays about the works," she said. It makes you feel like you're doing it for the requirement and not for yourself." The high school's service learning office, run by Beth Ansley, provides information on organizations seeking volunteers so that students will have an easier time fulfilling their hours.

   "It's ridiculous that people are opposing the requirements," said Amy Rouse, who this summer has worked at the Ronald McDonald House and has helped to rebuild a church in Clinton.

   "So many people won't do the service unless it's mandatory," Rouse said, "but once they start doing it, they'll really like it and hopefully it will become a part of their lives - like it has become a part of mine."

The 22nd SEA Games, hosted this year by Vietnam, has joined the international movement to rid sports of tobacco. For the first time, the regional sporting event will be tobacco-free under a landmark cooperative agreement signed in April 2003 between the World Health Organization (WHO), the 22nd SEA Games Organizing Committee and the Vietnamese Ministry of Health. Hanoi Health Department has organized a press seminar to celebrate and raise awareness about the tobacco-free SEA Games.

The 22nd SEA Games is the first games hosted by Vietnam and 10 countries from the Southeast Asian region with nearly 8,000 athletes and coaches will participate. It will be the first tobacco-free international sporting event in Vietnam, joining other international tobacco-free sporting events such as the FIFA World Cup 2002, and the Winter Olympic Games 2002.

The 22nd SEA Games will ban all sales, advertising and other promotion of tobacco products, and restricts smoking in all Games venues. The aim is to protect spectators, athletes, event staff, media and other visitors from the serious health hazards of second-hand tobacco smoke, as well as to change public attitudes about the social acceptability of smoking. Madame Pascale Brudon, WHO Representative in Vietnam, stated, "Vietnam has established 3 years ago a comprehensive, ambitious national tobacco control policy and a national tobacco control program. The tobacco-free 22nd SEA Games will be yet another area where Vietnam is leading the way for other countries in the region and the world in protecting its citizens from the debilitating and disastrous consequences of tobacco use."

WHO has provided funding and technical assistance to the SEA Games Organizing Committee and Vietnamese Ministry of Health to train of over 4,000 SEA Games organizers and volunteers on the implementation of the tobacco-free policy. An international team of trainers from the Ministry of Health, International Organization for Good Temper (lOGT), WHO and International Development Enterprises (IDE) began a series of national training workshops for volunteers in April, 2003. The tobacco-free SEA Games are an inspiration and a model for other sport events, big and small, not only in Vietnam but also in the Southeast Asian and Western Pacific Region.

Which sentence is not true when talk about SEA Games?

Almost as soon as World War II ended, the debate began over who had actually done the  most on the Allied side to ensure the defeat of the Axis powers. The Russians only needed to point to their twenty million plus war dead to justify their rights in Eastern Europe and their new  position as a great power on the world stage. Yet, Americans could also claim that they had done as much, if not more, as the Russians to defeat the Axis enemy. In hindsight, it is obvious that  despite its greater number of dead, the Russian effort ranks second place to the American. In  particular, the American effort seems greater in light of three crucial points: it was fighting at  extreme distances from its home territory; it simultaneously fought three different enemies on a multitude of complex fronts with air, naval, land forces; and finally, it supplied many other fighting  forces, including the Russians, with massive amounts ofmaterial. 

The main fronts of World War II were in North Africa, Italy, Western and Eastern Europe, the Pacific Ocean, China, and India. The United States military forces fought on or supported  every front, all of which were at extreme distances from the continental United States. A great logistical effort required to support both its own forces and those of many other nations. Above all,  supply ships were essential because without the supply ships, all would have been in vain.  Keeping the world's sea lanes free was one of the great accomplishments of the United States  Navy and her allies, especially the British and Canadians. This allowed ships to traverse great  distances and bring American and other Allied fighting forces to face the Axis powers. The Russians, on the other hand, were  fighting in their own country for much of the war and were close to their supply lines. They fought on one continuous font and did not have to travel far to meet the enemy. 

The United States fought all three great Axis powers during the war: Germany, Japan, and  Italy. While it cannot be denied that the Russian did the lion's share of the fighting against  Germany and the lesser Axis powers of Finland, Hungary, Romania, and Bulgaria for a longer  time, it was not until the last days of the war that Russia attacked Japan. As for the Italians, the  Russians only met the reluctant few whom Hitler managed to coerce for his Russian campaign. Another area to take into consideration is the strategic bombing campaign that the Americans and  British waged against German industry, something that the Russians did not take part in at all.  Finally, with the exception of the Baltic Sea, the Russian navy played a very minor role in the war  compared to American's navy. Despite significant aid from the British, Australians, and New Zealanders, the Americans bore the brute of the Pacific fighting. 

The Chinese tied down a massive number of Japanese troops on the Asian mainland, but  they were supplied almost exclusively by the United States. American arms, support equipment,  food, and clothing went to the four corners of the world during the war even before American officially entered it in 1941. Indeed, the Russian Red Army rode into Eastern Europe on the wheels  of over 300,000 American trucks, fed itself on a diet of American canned ham, and wore 

American boots. Coupled with all this were billion-dollar loans with generous terms of interest, which America gave to its allies. American was the only Allied nation that did not need to borrow  any money during the war. 

An idea came to me, and I turned off the lights in the studio. In the dark ness, I put the  cello's spike into a loose spot on the carpet, tightened the bow and drew it across the open strings.  I took off my shirt and tried it again; it was the first time in my life I'd felt the instrument against  my bare chest. I could fell the vibration of the strings travel through the body of the instrument to  my own body. I'd never thought about that; music scholars always talk about the resonating properties of various instruments, but surely the performer's own body must have some effect on the sound. As I dug into the notes I imagined that my own chest and lung were extensions of the sound box; I seemed to be able to alter the sound by the way I sat, and by varying the muscular tension in my upper body. 
After improvising for a while, I started playing the D minor Bach suite, still in the  darkness. Strangely freed of the task of finding the right phrasing, the right intonation, the right bowing, I heard the music through my skin. For the first time I didn't think about how it would sound to anyone else, and slowly, joyfully, gratefully, I started to hear again. The note sang out,  first like a trickle, then like a fountain of cool water bubbling up from a hole in the middle of the desert. After an hour or so I looked up, and in the darkness saw the outline of the cat sitting on the floor in front of me, cleaning her paws and purring loudly. I had an audience again, humble as it was. 
So that's what I do now with the cello. At least once a day I find time to tune it, close my eyes, and listen. It’s probably not going to lead to the kind of come back I'd fantasized about for so long – years of playing badly have left scars on my technique, and, practically speaking, classical  musicians returning from obscurity are almost impossible to promote – but might eventually try giving a recital if I feel up to it. Or better yet, I may pay for Dr. Polk if our date at the concert goes well. Occasionally I fell a stab of longing, and I wish I could give just one more concert on the  great stage before my lights blink off, but that longing passes more quickly now. I take solace on the fact that, unlike the way I felt before, I can enjoy playing for myself now. I fell relaxed and expansive when I play, as if I could stretch out my arms and reach from one end of the apartment to the other. A feeling of the completeness and dignity surrounds me and lifts me up.

American music, in most of its various forms, can be traced back to the music of the  earliest African- Americans. Even though these Americans came here under the worst of  circumstances, they still brought with them traditions, and developed new traditions of their own, that have grown into what is recognized around the world today as American music. 

Musicians, like other artists, are usually quick to give credit where credit is due. Just as a  writer quotes his sources, a musician credits those musicians who inspired him. In the case of the  early African-Americans, that is not always easy. Many of the slaves who brought musical  traditions from Africa will never be known by name. No one wrote their history. Many of the slaves who sang work songs in the fields will never be known by name. No one wrote their history either. 

However, there is a lot that we do know. 

The first well-recognized form of African-American music was spirituals. Spirituals are religious songs. They are songs that tell a story or express emotions. Spirituals have a strong  rhythm. They are often sung by a group, sometimes with a leader who sings a line or two alone and a chorus that sings the refrain. Spirituals originated in the Southern United States. Spirituals sung by slaves often expressed the hope for freedom that was so important in their lives. Well know spirituals include "Go Down Moses," "Deep River," and "Swing Low SweetChariot." After slavery ended, spirituals began to spread to other parts of the United States. Harry  Thacker Burleigh was one of the first singers to perform spirituals on stage in a concert. Marian Anderson, well known for her classical singing, helped spirituals to gain a wider audience too.  Spirituals influenced the development of another well-known form of American music - the blues. The blues were a more individual style of music than spirituals. Blues were often sung  solo, and sometimes they were accompanied by guitar music. As the name suggests, the blues were often about sadness and facing troubles. However, the blues could also be funny, positive, and  even defiant. One blues singer, loved for her strong, beautiful voice, was Bessie Smith. Another  early blues musician was W. C. Handy. Handy was not only a musician, he also wrote music,  promoted concerts, and published bluessongs. 

During the time that the blues were spreading across the country, another style of music  was also quickly gaining in popularity. Ragtime was energetic music with a complicated,  syncopated beat. Often played on the piano, ragtime was the latest and most sophisticated in American popular music. The best-known  ragtime musician was probably Scott Joplin, who wrote many hit ragtime pieces for the piano  including "Maple Leaf Rag." 

Eventually, elements from all of these forms of music and more came back together. In  their own kind of melting pot, African rhythms, slave work songs, spirituals, blues, ragtime, and  other influences recombined to form the beginnings of that truly American art form - jazz. In the late 1800’s jazz was just beginning, but not long after the turn of the century, it would be the most popular American music. It would go on from there to worldwide popularity. Jazz would branch  out into many forms, and it would influence future styles of Americanmusic. 

Many musicians today credit earlier musicians such as Scott Joplin or Bessie Smith with inspiring their music. It’s a shame that they can’t also name the earliest African-Americans who  really began the traditions that led to the American music of today.
