   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."

Which of the following volunteer activities is NOT mentioned in the passage?

The Southeast Asian Games owes its origins to the Southeast Asian Peninsular Games or SEAP Games. On May 22, 1958, delegates from the countries in Southeast Asian peninsula attending the 3rd Asian Game's in Tokyo, Japan had a meeting and agreed to establish a sport organization. The SEAP Games was conceptualized by Laung Sukhumnaipradit, then Vice-President of the Thailand Olympic Committee. The proposed rationale was that a regional sports event will help promote cooperation, understanding and relations among countries in the Southeast Asian region.
Thailand, Myanmar, Malaysia, Laos, Vietnam and Cambodia (with Singapore Included thereafter) were the founding members. These countries agreed to hold the Games biennially. The SEAP Games Federation Committee was formed.
The first SEAP Games were held in Bangkok from 12-17 December , 1959 comprising more than 527 athletes and officials from Thailand, Myanmar, Malaysia, Singapore, South Vietnam and Laos participating in 12 sports. 
At the 8th SEAP Games in 1975, the SEAP Federation considered the inclusion of Indonesia and the Philippines. The two countries were formally admitted In 1977, the same year when SEAP Federation changed their name to Southeast Asian Games Federation (SEAGF), and the games were known as the Southeast Asian Games. Brunei was admitted at the 10th SEA Game in Jakarta, Indonesia, and East Timor at the 22nd SEA Games in Hanoi, Vietnam. 
The 2007 Southeast Asian Games were held in the Thailand, which started from 6 December and ended on 15 December 2007, hosting the biennial event for the sixth time and it was also the most protested SEAG ever. The next host for the SEA Games is Laos. It is Laos' first time at the host for the biannual games.

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.

      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 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.

According to the text, The tobacco _______

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.

Scientists chose twins for their study because .......................

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.

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.

Before electricity, what was sometimes passed through pipes to heat rooms?

Games and sports are an important and essential part of a person's life. Along with the study, games, and sports are also important. Hence, most schools conducts various games competitions and sports. Along with the mental development of every person, physical development is also which needs to be taken into consideration. Sports is an important part of a student’s life as well. So, what is the importance of sports and games? 
Sports gives us a good exercise which makes us physically strong and increases our stamina and strength. Regular sports activities make us active and lead to good health. Playing Games makes us aware of our environment i.e. Makes us mentally awake and increases our concentration power. Various Games needs good strategies for better performance and teamwork, so it increases our thinking ability and teaches us the power of teamwork and to find a way out of difficult situations. Games and sports also need a lot of energy. It makes us energetic. Games and Sports needs a lot of cooperation between the players. Hence it increases cooperation with each other.
And at last, all of the games have their own rules and regulations which if not followed, leads to negative points. Hence, we can say that it teaches us the importance of following rules in life.

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.

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 “They” in paragraph 2 refers to _______.

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.

According to the passage, why is light coloring an advantage  to large desert animals?

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.

Based on the information in paragraph 3, what can be inferred about the cellist's  attitude toward playing? 

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 purpose of the passage is to ________.
