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.

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.

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.

   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.

A typical African woman spends _______ collecting firewood every day.

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.

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 many sports were there in The 24th SEA Games?

The best explainer videos are realized by great background score. When was the last time you watched a silent movie? Never? Not for a while? A long while? Even if you remember watching one, it would still have had a background score, or you’ve accidentally pressed the mute button!
The importance of background music and sound effects for your explainer video, therefore, cannot be overstated. You may not need a full blown orchestra or classy jazz tones to create the mood, but whether going for a subtle effect, a professional demonstration or simply trying to attract customers, music is a must. Explainer videos have the emotional quotient working for them and music is just going to add more to make the viewers relate to the pain points you are highlighting in your video. Imagine if your favorite video game has no background music or sound effects to back the amazing graphics? Would you play it with the same feel and excitement? Nah! Same is the case with your explainer videos. They need to and should have apt sound effects to make them worth your viewer’s time.
While the focus of explainer videos production is more on passing the desired information and explaining technical and complex procedures easily, it doesn’t mean you’ll be distracting your viewers with the background music. The sound effects and music is not going to take the message away from your explainer, it’s just going to enhance it and turn it more watchable and share-able. Even if your video doesn’t require a background score, it must include some sound effects or else it would be not so good an experience for those who choose to watch it

The word “score” in paragraph 1 can be replaced by ______.

The primary attraction of snorkeling is the opportunity to observe underwater life in a natural setting, such as coral reefs, fish, starfish, and mollusks. Other organisms that can be seen while snorkeling include various forms of seaweed, jellyfish, shrimp and sea turtles. Snorkeling requires no special training, only the ability to swim and to breathe through the snorkel. However, it is considered advisable that one get some instruction from a tour guide, dive shop, or equipment rental shop, any of which often can be found around popular snorkeling locations. Instruction generally covers equipment usage, basic safety, what to look for, and what to look out for, including how not to damage fragile organisms such as coral. As with scuba diving, it is always recommended that one, should not snorkel alone, but rather with a friend, a guide, or a tour group

Swim fins used in snorkeling are usually longer than those used in diving. Snorkel is a tube about thirty centimeters (twelve inches) long, usually J-shaped, fitted with a mouthpiece, and constructed of rubber or plastic. It is used for breathing air from above the water surface when the mouth and nose are submerged, either when snorkeling or during a surface swim before or after scuba diving. The snorkel usually has a piece of rubber that attaches the snorkel to the outside of the strap of the diving mask, as sticking the snorkel in between the strap and the mask could cause the mask to leak, or risk losing the snorkel should the diver choose to switch to scuba.

Typically, the diving mask also serves to prevent breathing through the nose, so that one is forced to breathe through the snorkel. This also provides some negative pressure which helps keep the .mask sealed against the face, though attempting to breathe out through the nose can break this seal and fog the mask.

A snorkeler should not ________.

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine, Beyond these simple and direct uses, those forms have not much adaptability.
On the other hand, we make use of electricity in thousands of ways. From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator,   and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace, or to boil a jug for a  cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances.
To generate electricity, huge turbines or generators must be turned. In  Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation.
Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

Psychologists have debated a long time about whether a child's upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however, argue that the potential for great achievement can be developed. The truth lies somewhere between these two extremes.
It seems very obvious that being born with the right qualities from gifted parents will increase a child's ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, "To have a fast car, you need both a good engine and fuel.” Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical twins that were separated shortly after birth and brought up by different pa rents. They found that achievement was based on intelligence, and later influenced by the child's environment
One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every possible opportunity to develop its abilities. That twin, though starting out with the same degree of intelligence as the other, performed even better.
This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child's intelligence and ability are developed. However, there is no link between intelligence and the socioeconomic level of a child's family.  In other words, it does not matter how poor or how rich a family is, as this does not affect intelligence.
Gifted people cannot be created by supportive parents, but they can be developed by them.
One professor of music said that outstanding musicians usually started two or three years earlier than ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years' hard work and training in order to reach the level they were capable of attaining.
People who want to have very gifted children are given the following advice:
- Marry an intelligent person.
- Permit children to chase their own interests rather than the interests of the parents.
- Start a child's education early but avoid pushing the child too hard.
- Encourage children to play; for example, playing with musical instruments is essential for a child who wants to become an outstanding musician.

The remark: "To have a fast car, you need both a good engine and fuel." in the passage means that in order to become a genius, ............................

   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.

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.

In paragraph 1, what does the world it refer to in the sentence, "I took off my shirt and  tried it again."?

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.

All of following are mentioned in paragraph 2 as part of the cellist's new way of  playing EXCEPT ...................

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. 
      New research shows that long-term changes in diseases in ocean species coincides with decades of widespread environmental change. The paper, "Increases and decreases in marine disease reports in an era of global change," was published Oct. 9 in Proceedings of the Royal Society B.
      Understanding oceanic trends is important for evaluating today's threats to marine systems, and disease is an important sentinel of change, according to senior author Drew Harvell, professor of marine biology at Cornell University. "Disease increases and decreases can both be bad news," said lead author Allison Tracy, who studied with Harvell. "The long-term changes in disease that we see here may result from anthropogenic pressure on plants and animals in the ocean." The researchers examined marine infectious disease reports from 1970 to 2013, which transcend short-term fluctuations and regional variation. They examined records of corals, urchins, mammals, decapods, fish, mollusks, sharks, rays, seagrass and turtles.
       For corals and urchins, reports of infectious disease increased over the 44-year period. In the Caribbean, increasing coral disease reports correlated with warming events. It is widely known that coral bleaching increases with warming, but Harvell said they have established a long-term connection between warming and coral disease. "We've finally linked a coral killer like infectious disease to repeated warming bouts over four decades of change," she said. "Our study shows that infectious disease reports are associated with warm temperature anomalies in corals on a multi-decadal scale." These results improve understanding of how changing environments alter species interactions, and they provide a solid baseline for health of marine life in the period studied.

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