The LED Lighting Revolution
If you have picked up any electronics magazines recently, you have probably heard about LEDs; yet chances are, you probably don’t realize why they are so special. The truth is that these tiny light bulbs are helping to improve watches, remote controls, televisions, and a host of other projects. Diodes are components that enable energy to flow in one direction, while simultaneously blocking the current from the opposite direction. This is similar to how a valve works on a faucet. If electronic manufacturers require currents to flow in several directions, then multiple diodes will be included in the circuit design. With LEDs, every time a current passes through them, a light is emitted. LED is short for light-emitting diode. Although they have only recently waves in the past decade or so, early models have been around since 1962. There are several benefits that LEDs offer when compared to incandescent or fluorescent lighting. For starters, they have extremely long-life spans in the range of l00,000 hours even in the toughest conditions. They also require far less energy than power sources, which can save users money over the long run. Since LEDs don’t contain moving parts like other bulbs, they can withstand heavy impacts without getting damaged. Finally, they don’t require any _warm-up time_ so they instantly light up when switched on. The only drawback is that they are still a more expensive to purchase at the moment. LEDs were first used on digital clocks, but they have come a long way since then. They have certainly done a lot to improve TV technology. LED TVs have been a hit because they can be built extremely thin, yet also offer power-saving benefits. LED TVs also provide a wider range of colour, which allows for more lifelike and vivid images. In the future, organic LEDs, or OLEDs, will bring additional benefits for viewers. OLEDs are even more flexible than LEDs, so manufacturers will be able to create bent display screens and lights. Therefore, you will be able to roll up your living room TV set and pack it in your suitcase. In other words, LED and OLED technology will likely be lighting up your life for years to come.
8. The tone of the passage is ________

William Sydney Porter (1862-1910), who wrote under the pseudonym of O. Henry, was born in North Carolina. His only formal education was to attend his Aunt Lina’s school until the age of fifteen, where he developed his lifelong love of books. By 1881 he was a licensed pharmacist. However, within a year, on the recommendation of a medical colleague of his Father’s, Porter moved to La Salle County in Texas for two years herding sheep. During this time, Webster’s Unabridged Dictionary was his constant companion, and Porter gained a knowledge of ranch life that he later incorporated into many of his short stories. He then moved to Austin for three years, and during this time the first recorded use of his pseudonym appeared, allegedly derived from his habit of calling “Oh, Henry” to a family cat. In 1887, Porter married Athol Estes. He worked as a draftsman, then as a bank teller for the First National Bank.

   In 1894 Porter founded his own humor weekly, the “Rolling Stone”, a venture that failed within a year, and later wrote a column for the Houston Daily Post. In the meantime, the First National Bank was examined, and the subsequent indictment of 1886 stated that Porter had embezzled funds. Porter then fled to New Orleans, and later to Honduras, leaving his wife and child in Austin. He returned in 1897 because of his wife’s continued ill-health, however she died six months later. Then, in 1898 Porter was found guilty and sentenced to five years imprisonment in Ohio. At the age of thirty five, he entered prison as a defeated man; he had lost his job, his home, his wife, and finally his freedom. He emerged from prison three years later, reborn as O. Henry, the pseudonym he now used to hide his true identity. He wrote at least twelve stories in jail, and after re-gaining his freedom, went to New York City, where he published more than 300 stories and gained fame as America’s favorite short Story writer. Porter married again in 1907, but after months of poor health, he died in New York City at the age of forty-eight in 1910. O. Henry’s stories have been translated all over the world.

Read the following passage and choose the best answer (A, B, C, D):
Glenbrook South (GBS) High School is in a suburb of Chicago, lllinois, in the United States. It is an award-winning school with a highly competent teaching staff. It has over 400 Asian Pacific American students-over 17 percent of the students in the school. Of these, the majority are Korean American. This is very unusual in a state where Korean Americans are less than 1 percent of the population. The interactions of the Korean American students at GBS were the subject of an article in Asian Week magazine. Different Korean American students react differently to being in a high school where most students are white. Professor Pyong Gap Min, an expert on Korean life in America, believes that Korean Americans in this situation can sometimes feel inhibited or ashamed of their Korean identity. Asian Week interviewed a number of GBS students, and each had a different attitude. Eighteen-year-old Alice said that she used to spend time only with Korean American friends. Although she felt secure with those friends, she found herself motivated to form closer relationships with non-Koreans, too. She said that she felt she was missing out on new experiences and challenges. Seventeen-year-old John moved in the opposite direction. In junior high school, most of John's friends were white. After coming to GBS, his sense of his Korean American identity was restored, and he decided to have mainly Korean American friends. He feels that he and his Korean American friends understand each other better. For example, they understand about severe parental pressures to succeed at school; John felt his white friends couldn't really understand. Sixteen-year-old Paul has some Korean American friends, but he says he spends most of his time with his white friends. He is often the only Asian American in the group, but he doesn't mind. What Paul likes about the white culture is that he can be more radical - he can be as loud and funny as he wants to be. He says he doesn't see as much of that among the Asian students. Without belittling the importance of what these students had to say, it's important to remember that their opinions at this phase of their lives are bound to change as they grow into adulthood. But these honest opinions can help US better understand issues of cultural relations, and their honesty might help Americans from different cultural groups to get along better in the future.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
The lack of printing regulations and the unenforceability of British copyright law in the American colonies made it possible for colonial printers occasionally to act as publishers. Although they rarely undertook major publishing project because it was difficult to sell books as cheaply as they could be imported from Europe, printers in Philadelphia did publish work that required only small amounts of capital, paper, and type. Broadsides could be published with minimal financial risk. Consisting of only one sheet of paper and requiring small amounts of type, broadsides involved lower investments of capital than longer works. Furthermore, the broadside format lent itself to subjects of high, if temporary, interest, enabling them to meet with ready sale. If the broadside printer would know this immediately, there would be no agonizing wait with large amounts of capital tied up, books gathering dust on the shelves, and creditors impatient for payment.
In addition to broadsides, book and pamphlets, consisting mainly of political tracts, catechisms, primers, and chapbooks were relatively inexpensive to print and to buy. Chapbook were pamphlet-sized books, usually containing popular tales, ballads, poems, short plays, and jokes, small, both in formal and number of pages, they were generally bound simply, in boards (a form of cardboard) or merely stitched in paper wrappers (a sewn antecedent of modern-day paperbacks). Pamphlets and chapbooks did not require fine paper or a great deal of type to produce they could thus be printed in large, cost-effective editions and sold cheaply.
By far, the most appealing publishing investments were to be found in small books that had proven to be steady sellers, providing a reasonably reliable source of income for the publisher. They would not, by nature, be highly topical or political, as such publications would prove of fleeting interest. Almanacs, annual publication that contained information on astronomy and weather patterns arranged according to the days, week, and months of a given year, provided the perfect steady seller because their information pertained to the locale in which they would be used.

Alemur is a unique animal. When you look at a lemur, it might be hard to tell what you are really looking at. With their huge dark eyes and lush fur, lemurs are very cute, but what animal family are they from? Some lemurs look like a cross between a cat and a dog. Some look a little like squirrels, while others resemble monkeys. Why do they look so strange? To answer to this question we need to understand the lemur's history and genetics. In modern biology, lemurs are called prosimians. This means before monkeys. Remarkably, lemurs, monkeys, apes, and humans all share a common ancestor from about 50 million years ago. Monkeys, apes, and humans developed together in one direction. However, lemurs developed differently and slowly because of their geographical location. All lemurs come from the island of Madagascar, located off the east coast of Africa. Madagascar split off from mainland Africa 50 million years ago. It is believed that the first prosimians traveled to Madagascar on floating trees and plants. The prosimians that traveled to Madagascar were isolated from the rest of Africa. Predators, like dogs or cats, did not make it to Madagascar. Since there were no dangerous threats, prosimians did not have to evolve as quickly as other primates did. (primates: any nimal that belongs to the group of mammals that includes humans, apes, and monkeys.) Over time, the original prosimians evolved into lemurs. Lemurs have changed in some ways over those 50 million years, but they are much more similar to our shared ancestor than either humans, monkeys, or apes. Because of this, their bodies and behaviors hold clues about what out common ancestor looked like. Lemurs have four fingers and a thumb on their hands, and five toes on their feet, just like humans do. They have eyes and jaw bones that are similar to humans as well, but they have a wet nose, like a dog. Lemur behavior is also comparable to human behavior, as they live in social groups. Like apes and humans, lemurs travel together, groom one another, fight each other, and play together. Lemurs, however, have simpler friend and family relationships. Recently, lemurs have been studied in captivity. Like their distant chimpanzee and monkey cousins, they can be taught to use tools and to solve complicated problems. The word lemur means ghost. While the name probably comes from their huge reflective eyes and their strange, haunting cries, lemurs are ghosts in a way. They are living ghosts that remind US where we came from, and also give US clues about how humans evolved.

Genetics is the study of hereditary characteristics that are passed down from one generation of living organisms to another. Although farmers have used selective breeding to improve the resilience of crops and animals, it wasn't until the mid-1800s that Gregor Mendel started the science of genetics as we know it today. Following Mendel's methods, scientists have discovered "chromosomes" and "DNA". With the ability to study DNA, scientists were able to study the genetic differences between races. Modern genetics discovered that all humans are descendants of "Mitochondrial Eve," a woman who lived over 150,000 generations have passed, and many subtle differences are now evident. Humans share at least 99% of their genetic makeup. A 1% difference may not seem like much, but when you consider that a chimpanzee shares 98% of human genes, you realize how much a 1% difference makes! Africans are more closely related to Europeans than any other two groups despite the fact that they differ so much in appearance. The biggest genetic differences are found between Africans and the native populations of Nord America (22%). However, it is essential to note that the genetic differences between people of the same race are much greater than the differences between people of different races. This means that the argument which claims that genets differences make one race superior to another is nothing but a tall story. The differences in various populations may also be the result of circumstances rather than genetic makeup. Factors such as climate, diet, health care, education, and employment as well as other socioeconomic factors are all influential. However, there are some traits which are genetic, for example, then is a much higher incidence of sickle cell anemia among black populations that any other population group. Adult African-Americans and Latinos have twice as many cases of diabetes than Caucasians. In the U.S, Latinos suffer more deaths from liver disease than other races. Europeans suffer more from heart disease and cancer. Genes not only affect our susceptibility to disease, they also affect our physical attributes. The Dinka people from the Sudan are considered to be the tallest people with men having an average height of 6ft 3 in, while women hit the big time with an impressive 5ft 3 in. This contrasts sharply with the Pygmy tribes who get the short end of the stick at only about 4ft 11 in tall. Genetic differences may help US to tailor health service to people of different races or to detect life threatening diseases early. However, they are not significant enough to support the claim that one race is superior to another. In fact, our modern scientific understanding of human genetic diversity flit in the face of almost all our social stereotypes.

Rain pounded down on the roof. I was trying to read but the sound was too loud. I couldn’t help myself from being a little grumpy. I wanted to be outside playing, but the rain was keeping me inside. My mom had gone to the grocery store, and my dad was spending Saturday at the office. I had planned to spend the day hiking, but Mother Nature decided that today was the perfect day for rain. It meant that I would have to entertain myself. I spent most of the morning playing with my stuffed animals and reading. I was sitting next to the window staring out when I got a strange idea: why not just go outside anyway? I put on my boots and a big raincoat and stepped out into the wet world. It was raining hard but it wasn’t cold. All I could hear were raindrops and the wind. I decided to go on my hike anyway. My feet didn’t make any sound on the wet ground and the forest seemed different. I went to my favourite place and sat down. In the summer, my best friend Ellen and I would come here and sit for hours. It was our special place. All of a sudden, I thought I heard someone shouting my name. I turned and saw Ellen walking up behind me. “Oh my Gosh! It’s really you, Martha!” she said. “I can’t believe that you are out here right now. I thought I would be the only person crazy enough to go for a walk in the rain.” I was very happy to have some company. We decided that hiking in the rain was just as fun as hiking in the sunshine. We planned on hiking in the rain again.
