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.

   Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication – having a mobile phone shows that they are cool and connected.

   The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

   On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn’t remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer’s doctor didn’t agree.

   What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

   As the discussion about their safety continues, it appears that it’s best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it’s wise not to use your mobile phone too often.

A study was set up to examine the old marriage advice about whether it's more important to be happy or to be right. Couples therapists sometimes suggest that in an attempt to avoid constant arguments, spouses weigh up whether pressing the point is worth the misery of marital discord. The researchers from the University of Auckland noticed that many of their patients were adding stress to their lives by insisting on being right, even when it worked against their well-being.
The researchers then found a couple who were willing to record their quality of life on a scale of 1 to 10. They told the man, who wanted to be happy more than right, about the purpose of the study and asked him to agree with every opinion and request his wife had without complaint, even when he profoundly didn't agree. The wife was not informed of the purpose of the study and just asked to record her quality of life.
Things went rapidly downhill for the couple. The man's quality-of-life scores fell, from 7 to 3, over the course of the experiment. The wife's scores rose modestly, from 8 to 8.5, before she became hostile to the idea of recording the scores. Rather than creating harmony, the husband's agreeableness led to the wife becoming increasingly critical of what he did and said (in the husband's opinion). After 12 days he broke down, and the study was called off because of severe adverse outcomes."
The researchers concluded, shockingly, that humans need to be right and acknowledged as right, at least some of the time, to be happy. They also noted this was further proof that if given too much power, humans tend to "assume the alpha position and, as with chimpanzees, they become very aggressive and dangerous." It is often said that there can be no peace without justice, and that's true of domestic sphere.
Obviously the results are to be taken with extreme caution, since this was just one couple with who-knows-what underlying issues beforehand. But the study's chief author, Dr. Bruce Arroll, maintains that the question of happiness vs. rightness, theoretically, could be settled by scientific inquiry with a wider sample. "This would include a randomized controlled trial,” he says. "However, we would be reluctant to do the definitive study because of the concern about divorce."

   In the 1960s, The Beatles were probably the most famous pop group in the whole world. Since then, there have been a great many groups that have achieved enormous fame, so it is perhaps difficult now to imagine how sensational The Beatles were at that time. They were four boys from the north of England and none of them had any training in music. They started by performing and recording songs by black Americans and they had some success with these songs. Then they started writing their own songs and that was when they became really popular. The Beatles changed pop music. They were the first pop group to achieve great success from songs they had written themselves. After that it became common for groups and singers to write their own songs. The Beatles did not have a long career. Their first hit record was in 1963 and they split up in 1970. They stopped doing live performances in 1966 because it had become too dangerous for them - their fans were so excited that they surrounded them and tried to take their clothes as souvenirs! However, today some of their songs remain as famous as they were when they first came out. Throughout the world, many people can sing part of a Beatles song if you ask them.

   Most languages have several levels of vocabulary that may be used by the same speakers. In English, at least three have been identified and described.

   Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the levels of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both Colloquial usage and slang are more common in speech than in writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events.

   It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population.

   Finally, it is worth noting that the terms "standard", "colloquial" and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressions.

Which of the following is the main topic of the passage?

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.

   Supernovas are the most powerful and spectacular outbursts known in nature. What is called a Type II supernova is due to the collapse of a massive star, at least eight times as massive as the sun, that has used up its main nuclear fuel and produced a nickel-iron core. When this core can no longer support the pressure of the star’s outer layer, it collapses to form a neutron star of immense density. Over 2,500 million tons of neutron star packed into a matchbox. Its temperature is around 100,000 million degrees centigrade.

   Multitudes of neutrons are produced in the collapsed star, which pass directly through the star into space, and this release of neutrons causes the core to respond with a shock wave that moves outward.

   When it meets the material that is falling inward, the result is a catastrophic explosion. Sometimes most of the star’s material is blown away, leaving only a small, incredibly dense remnant that may be a neutron star or, in extreme cases, a black hole.

   A supernova is often more than 500 million times as luminous as the sun. A supernova remnant (SNR) may be detectable as a pulsar, an example of which is the Crab Nebula, known to be a remnant of the supernova observed in the year 1054. The 1987 supernova in the Large Cloud of Magellan had a low peak luminosity by supernova standards, only about 250 million times that of the sun. As its brightest the supernova shone as a star between magnitudes 2 and 3, even though it was 170,000 light-years away.

What can be inferred from the passage about supernovas?

Walt Disney was born in 1901 in Chicago, but soon moved to a small farm near Marceline, Missouri. From this rural and rather humble beginning he later became one of the most famous and beloved motion-picture producers in history. Although he died in 1966, his name and artistic legacy continue to influence the lives of millions of people throughout the world.

After several years of barely making ends meet as a cartoon artist operating from his Los Angeles garage, Disney had his first success in 1928, with his release of a Mickey Mouse cartoon. Throughout the next decade, he continued to produce a number of cartoons, and develop more of his highly profitable and enduring creations, such as Donald Duck and Pluto. In the late 1930s, he issued full-length cartoon film. Snow White became an instant commercial and critical success. This was only the first of many films, both animated and not, produced by Disney and his studio.

But as renowned as Disney name is for cartoon and monies, it is probably best known for a string of spectacular amusement and theme parks. Starting with California's Disneyland in 1955 and culminating with the fantastically successful Disney World and EPCOT Center in Florida, Disney became a household name. In recent years, the theme park concept became international, with openings in Toyo and Paris. With the continuing success of Disney, the creation of future theme park are under discussion.

For more than six million American children, coming home after school means coming  back to an empty house. Some deal with the situation by watching TV. Some may hide. But all of  them have something in common. They spend part of each day alone. They are called “latchkey children”. They are children who look after themselves while their parents work. And their bad  condition has become a subject of concern. 
Lynette Long was once the principal of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was  constantly telling them to put the keys inside shirts. There were so many keys; it never came to  my mind what they meant.” Slowly, she learned that they were house keys. She and her husband began talking to the children who had keys. They learned of the effect working couples and single parents were having on their children. Fear was the biggest problem faced by children at home alone. One in three latchkey children the Longs talked to reported being  frightened. Many had nightmares and were worried about their own safety. The most common way latchkey children deal with their fears is by hiding. They may hide  in a shower stall, under a bed or in a closet. The second is TV. They often turn the volume up. It’s  hard to get statistics on latchkey children, the Longs have learned. Most parents are slow to admit  that they leave their children alone

Synchronized swimming is a hybrid form of swimming, dance and figure skating which consists of swimmers (either individuals, duets, trios, teams or combos) performing a synchronized routine of elaborate and dramatic moves in the water, accompanied by music. Synchronized swimming demands advanced water skills, and requires strength, endurance, flexibility, grace, artistry and precise timing, not to mention exceptional breath control while upside down underwater.

Developed in the early 1900s in Canada, it is a sport performed almost exclusively by women, although there is some participation by men. In its early form it was sometimes known as “water ballet”.

It is a Summer Olympic Games sport. First demonstrated in 1952, it has been an official event since 1984. Olympic and World Championship competition is not currently open to men, but other international and national competitions allow male competitors. Both USA Synchro and Synchro Canada allow men to compete with women. In competition, competitors show off their strength, flexibility, and aerobic endurance required to perform difficult routines. Swimmers perform two routines for the judges, one technical and one free.

Synchronized swimming is a harmonious combination of swimming, dance and figure skating.

Choose the letter A, B, C or D to answer these following questions:

Choose the letter A, B, C or D to answer these following questions: Most of us tend to think of production when we think of mass media industries. After all, it is the output of this production – the papers we read, the cable TV shows we watch – that grab our attention, make us happy or angry, interested or bored. Moreover, most public discussion about communication tends to be about production. The latest gossip about that actor will be in what film, the angry comments a mayor makes about the violence on local TV news, the newest CDs by an up-and-coming group – these are the kinds of topics that focus our attention on the making of content, not its distribution or exhibition.
Media executives know, however, that production is only one step in the arduous and risky process of getting a mass media idea to an audience. Distribution is the delivery of the produced material to the point where it will be shown to its intended audience. The activity takes place out of public view. We have already mentioned the NBC acts as a distributor when it disseminates television programming via satellite to TV stations. When Philadelphia Newspapers Inc. delivers its Philadelphia Inquirer to city newsstands, when Twentieth – Century – Fox moves its Musicland stores, they are involved in distribution to exhibitions.

   Traditionally in America, helping the poor was a matter for private charities or local governments. Arriving immigrants depended mainly on predecessors from their homeland to help them start a new life. In the late 19th and early 20th centuries, several European nations instituted public-welfare programs. But such a movement was slow to take hold in the United States because the rapid pace of industrialization and the ready availability of farmland seemed to confirm the belief that anyone who was willing to work could find a job.

   Most of the programs started during the Depression era were temporary relief measures, but one of the programs Social Security – has become an American institution. Paid for by deductions from the paychecks of working people, Social Security ensures that retired persons receive a modest monthly income and also provides unemployment insurance, disability insurance, and other assistance to those who need it. Social Security payments to retired persons can start at age 62, but many wait until age 65, when the payments are slightly higher. Recently, there has been concern that the Social Security fund may not have enough money to fulfill its obligations in the 21st century, when the population of elderly Americans is expected to increase dramatically. Policy makers have proposed various ways to make up the anticipated deficit, but a long-term solution is still being debated. In the years since Roosevelt, other American presidents have established assistance programs. These include Medicaid and Medicare; food stamps, certificates that people can use to purchase food; and public housing which is built at federal expense and made available to persons on low incomes. Needy Americans can also turn to sources other than the government for help. A broad spectrum of private charities and voluntary organizations is available. Volunteerism is on the rise in the United States, especially among retired persons. It is estimated that almost 50 percent of Americans over age 18 do volunteer work, and nearly 75 percent of U.S. households contribute money to charity.

That Social Security payments will be a burden comes from the concern that ______.
