Fiberscopes are one of the most are one of the most important outcomes of he science of fiber optics. Fibers made of glass and transparent acrylic plastic are capable of conveying light energy, and when thousands of these fibers are combined in what is called a fiberscope, they can transmit images. The most common fiberscopes contain about 750,000 fibers, each 0.001 centimeter, or 10 microns, in diameter. For certain uses, the diameter of the fiber may be as small as 5 microns. Fiberscopes have a wide range of applications. In the medical field, physicians use fiberscopes to examine internal organs and as an aid in delicate surgeries. Miniature probes have also been developed to view muscle fiber, skin tissue, and blood cells. Fiberscopes have also found varied uses in industry, particularly to inspect or control operations in inaccessible areas. Bundles of fiberscopes fused together in a solid plate, called a faceplate, are being used in the manufacture of television tubes and other cathode- ray tube devices. The most far reaching applications of fiber-optic technology are in communication. Optical fibers carry voice messages for telephone service. The sound of the voice is electronically broken down into thousands of pulses per second, which causes a transmitting laser to send coordinated pulses of light through the optical fibers. At the receiving end, the light pulses are converted to electrical signals and the voice message is reconstructed. Light-wave communication systems can handle an immensely greater number of telephone calls and television programs than the current system, and they will form the basis of the “electronic superhighway” expected to crisscross the nation in the near future of the information age.

A survey is a study, generally in the form of an interview or a questionnaire, which provides information concerning how people think and act. In the United States, the best-known surveys are the Gallup poll and the Harris poll. As anyone who watches the news during campaigns presidential knows, these polls have become an important part of political life in the United States.
North Americans are familiar with the many “person on the street” interviews on local television news shows. While such interviews can be highly entertaining, they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such samples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the news people select. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population.
In preparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately.
There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interviewer can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions and probe for a subject’s underlying feelings  and reasons. However, questionnaires have the advantage of being cheaper and more consistent.

Read the following passage and choose the best answer (A, B, C, D):
Perhaps the most striking quality of satiric literature is its freshness and its originality of perspective. Satire itself, however, rarely offers original ideas. Instead, it presents the familiar in a new form. Satirists do not offer the world new philosophies. What they do is look at familiar conditions from a perspective that makes these conditions seem foolish, harmful, or affected. Satire jars us out of complacence into a pleasantly shocked realization that many of the values we unquestioningly accept are false. Don Quixote makes chivalry seem absurd; Brave New World ridicules the pretensions of science; A Modest Proposal dramatizes starvation by advocating cannibalism. None of these ideas is original. Chivalry was suspect before Cervantes, humanists objected to the claims of pure science before Aldous Huxley, and people were aware of famine before Swift. It was not the originality of the idea that made these satires popular. It was the manner of expression, the satiric method, that made them interesting and entertaining. Satires are read because they are aesthetically satisfying works of art, not because they are morally wholesome or ethically instructive. They are stimulating and refreshing because with commonsense briskness they brush away illusions and secondhand opinions. With spontaneous irreverence, satire rearranges perspectives, scrambles familiar objects into incongruous juxtaposition, and speaks in a personal idiom instead of abstract platitude. Satire exists because there is need for it. It has lived because readers appreciate a refreshing stimulus, an irreverent reminder that they live in a world of platitudinous thinking, cheap moralizing, and foolish philosophy. Satire serves to prod people into an awareness of truth, though rarely to any action on behalf of truth. Satire tends to remind people that much of what they see, hear, and read in popular media is sanctimonious, sentimental, and only partially true. Life resembles in only a slight degree the popular image of it.

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 from 24 to 28:

In Southeast Asia, many forests have been cut down to produce timber and to clear land for farms and industries. The destruction of forests has reduced the living space of wildlife. Much of Asia’s wildlife is also threatened by over-hunting. Many people kill animals for food or hunt them to sell to zoos, medical researchers, and pet traders. Because of habitat destruction and over-hunting, many large Asian animals, including elephants, rhinoceroses, and tigers, have become endangered.

In China, people have cut down most of the forests for wood, which has caused serious soil erosion. The soil is deposited in rivers and streams, which lowers the quality of the water. The Huang He, or Yellow River, is so named because the light-colored soil gives the water a yellowish color. The soil has also raised the river-bed. As a result, the Huang He often floods, causing great property damage and loss of life along its banks.

   Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing strip to attract the specific insect the orchid has chosen as its pollinator.

   To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.

   Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.

The stylistic innovation in painting known as Impressionism began in the 1870s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated on the play of light over objects, people, and nature, breaking up seemingly solid surfaces, stressing vivid contrast between colors in sunlight and shade, and depiction reflected light in all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoors to complete the work from memory. Some of the Impressionists' painting methods were affected by technological advances. For example, the shift from the studio to the open air was made possible in part by the advent of cheap rail travel, which permitted easy and quick access to the countryside or seashore, as well as by newly developed chemical dyes and oils that led to collapsible paint tubes, which enabled artists to finish their paintings on the spot. Impressionism acquired its name not from supporters but from angry art lovers who felt threatened by the new painting. The term "Impressionism" was born in 1874, when a group of artists who had been working together organized an exhibition of their paintings in order to draw public attention to their work. Reaction from the public and press was immediate, and derisive. Among the 165 paintings exhibited was one called Impression: Sunrise, by Claude Monet (1840- 1926), viewed through hostile eyes, Monet's painting of a rising sun over a misty, watery scene seemed messy, slapdash, and an affont to good taste. Borrowing Monet's title, art critics extended the term "Impressionism" to the entire exhibit. In response, Monet and his 29 fellow artists in the exhibit adopted the same name as a badge of their unity, despite individual differences. From then until 1886 Impressionism had all the zeal of a "church", as the painter Renoir put it. Monet was faithful to the Impressionist creed until his death, although many of the others moved on to new styles.

   Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn’t exist. That changed because of a man named Joseph Merlin. Merlin’s work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.

   One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room. Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention as he dreamed of arriving at the party on wheels while playing the violin.

   On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin’s grand entrance for a long time!

People thought Merlin was a dreamer because he__________.

Read the passage carefully, then decide whether the following statement are true (T) or false (F)

The proverb 'A friend in need is a friend indeed.' means that we shall know who our real friends are when we are in need. Those who desert us when we are in difficulty are just unfaithful friends.

A true friend would remain with us whether we are rich or poor. Some people be friend the rich, simply for the sake of getting benefits from them.

It is useless to have insincere friends because these friends remain with us as long as we are rich or powerful. It is better to have one or two good friends rather than having hundreds of insincere ones.

A true friend will stand by us in our trials and tribulations. He will be a great source of consolation and comfort in our troubles. So we must be careful in choosing our friends. It is difficult to choose a sincere friend overnight; it takes years for us to find a sincere friend.

It's not worth having a lot of friends.

When Malaysia takes the ASEAN chair next year, it will face a huge challenge. Too few of us know enough about this grouping we call the Association of Southeast Asian Nations. We do not know what it means to be a part of ASEAN and why it is important to us. At the same time, pressure is mounting to reinvent ASEAN to make it more people-centric and less government-centric. The Heat speaks to Global Movement of Moderates CEO Saifuddin Abdullah on why ASEAN should mean more to us than just acronyms.
ASEAN people do not feel like they are a part of the community of Southeast Asian nations. This statement, backed up by survey findings, is pretty bizarre, and extremely hurtful too, considering that ASEAN is 47 years old today. “Interview 10 persons on the Street and you would perhaps get only one of them who knows about ASEAN,” says Datuk Saifuddin Abdullah. This CEO of Global Movement of Moderates (GMM) is not running down ASEAN; he’s confronting the truth as it impacts the project he has been entrusted with. Here’s more, in 2012, the ASEAN Secretariat conducted a survey that showed only 34% of Malaysians had heard of the ASEAN community. This compares with 96% of Laotians. Malaysia chairs ASEAN next year, and GMM is a member of the national steering committee organizing the ASEAN People’s Forum (APF), a platform designed to bridge the gap between governments and civil society. Never heard of it? You’re forgiven. The APF actually started off life in the 1990s, except it was called the ASEAN People’s Assembly (APA). It was held back to back with the ASEAN Summit, which is held twice a year. The APA is the forum where 10 leaders of government engage with 10 leaders of civil society in a half-hour meeting. “It was going well until one year when the chairman decided not to hold the APA, so it was discontinued until 2005 when Malaysia took the chairmanship of ASEAN again and founded the ASEAN People’s Forum (APF),” Saifuddin explains. In a perfect world, forums such as the APF or its predecessor APA would have worked perfectly to bridge the gap between government and civil society. However, as Saifuddin points out, Civil Society Organizations (CSOs) often do not see eye to eye with their governments. For instance this year, Myanmar is chair of ASEAN and in the APF, three member nations – including Malaysia – decided not to recognize the CSO leaders chosen as representatives so the APF did not take place. “This is where the GMM wants to play a role in ensuring that this situation does not arise again,” Saituddin says.
7. Which of the following statements is TRUE according to the passage?

By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1860-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.
 Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The common-sense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the nice balance of insulation and circulation needed for an efficient icebox.
 But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

Read the following passage and choose the best answer (A, B, C, D):
Music can bring US to tears or to our feet, drive US into battle or lull US to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that every reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet-sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system - an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For  example, the fact that whale and human music have so much in common even though our evolutionary paths have not interested for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene. Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers - and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazingly, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes - singing the new whales'songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

In many aspects of life, effective communication skills are extremely important. With good communication skills, people can enjoy better interpersonal relationships with friends and family. The following are some guides that can help you improve your communication skills.

Learn to listen

Listening is not the same as hearing; you should learn to listen not only to the words being spoken but also how they are being spoken and the non-verbal messages sent with them. You shouldn't think about what to say next while listening; instead clear your mind and focus on the message being received. Your friends, colleagues and other acquaintances will appreciate your good listening skills.

Try to understand other people's emotions

To understand other people's emotions, you should be sympathetic to other people's misfortunes and congratulate them on their achievements. To do this, you need to be aware of what is going on in other people's lives. It's crucial to maintain eye contact and do not be afraid to ask others for their opinions as this will help to make them feel valued.

Encourage

It's advised that you offer words and actions of encouragement, as well as praise, to others, which make other people feel welcome, valued and appreciated in your communications. If you let others know that they are valued, they are much more likely to give you their best. You should also try to ensure that everyone get involved in an interaction or conversation by using effective body language and open questions.

What should we do to involve everyone in an interaction or conversation?

In 1959, the government of Egypt was working on a plan to build a dam on the River Nile. It was called the Aswan Dam, and it was intended to generate electricity and allow the river water to be used for agriculture. There was one big problem with the plan, though. The dam would flood a nearby valley that contained ancient Egyptian treasures, including two enormous stone temples.
It can be difficult for governments to choose culture and history over economics. However, if countries always made decisions like this, the majority of the world's ancient sites would end up being destroyed. Luckily, UNESCO stepped in. They formed a committee that tried to convince Egypt to protect its ancient treasures. With support from many countries, they were finally successful. The huge temples were carefully removed from their original site and moved to a safe location so that the dam could be built.

After their success in saving the temples in Egypt, UNESCO went on to save more sites around the world. They protected lagoons in Venice, ruins in Pakistan, and temples in Indonesia. With industrialisation changing the world rapidly, there were many sites that needed to be saved. Eventually, UNESCO formed the World Heritage Organisation to protect important natural and historic sites wherever it was necessary.

By now, the World Heritage Organisation has protected hundreds of sites ranging from beautiful natural islands to buildings in large cities and ancient ruins. If you're able to visit any of the many protected sites, you'll agree it was worth it.
