Read the following passage and choose the best answer (A, B, C, D):
There are three valid arguments to support the preservation of endangered species. Aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world. Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us. Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for Nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

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

Câu 9:

Read the following passage and choose the best answer (A, B, C, D):
One of the major problems in the art world is how to distinguish and promote an artist. In effect, a market must be created for an artist to be successful. The practice of signing and numbering individual prints was introduced by James Abbott McNeill Whistler, the nineteenth-century artist best known for the painting of his mother, called "Arrangement in Grey and Black", but known to most of US as "Whistler's Mother". Whistler's brother-in- law, Sir Francis Seymour Haden, a less well-known artist, had speculated that collectors might find prints more attractive if they knew that they were only a limited number of copies produced. By signing the work in pencil, an artist could guarantee and personalize each print. As soon as Whistler and Haden began the practice of signing and numbering their prints, their work began to increase in value. When other artists noticed that the signed prints commanded higher prices, they began copying the procedure. Although most prints are signed on the right-hand side in the margin below the image, the placement of the signature is a matter of personal choice. Indeed, prints have been signed within the image, in any of the margins, or even on the reverse side of the print. Wherever the artist elects to sign it, a signed print is still valued above an unsigned one, even in the same edition.

1. What was true about the painting of Whistler's mother?

Câu 19:

Read the following passage and choose the best answer (A, B, C, D):
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.

Câu 21:

Read the following passage and choose the best answer (A, B, C, D):
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.

1. Why did lemurs develop more slowly and quite differently?

Câu 28:

Read the following passage and choose the best answer (A, B, C, D):
Some technological developments are the results of years of diligent work. Others are stumbled upon by accident. The discovery of X-rays is in the second category. In 1895, X-ray radiation was accidentally discovered by a physicist named Wilhelm Rontgen, while he was working in his lab. Rontgen discovery greatly advanced medical science. One night in 1895, Wilhelm Rontgen was working with an electric device called a Crookes tube. A Crookes tube is a glass tube with metal components inside it. When turned on, the tube produces a stream of electrons. Rontgen and other scientists observed a new form of energy escaping from the front end of the Crookes tube. Rontgen wanted to be the first to discover this new mysterious energy. To do this, he needed to make sure the tube was covered with black cardboard. This would make the room completely dark and allow him to better see this new form of energy. Rontgen was hoping to observe this new energy on a special screen that would be placed right in front of the Crookes tube. Amazingly, before the screen was placed near the Crookes tube, Rontgen already noticed the screen was glowing. He bought the screen closer, and the glow became brighter. (1) He then placed a book between the end of the tube and the screen-the glow was still there. (2) Rontgen realized that a new and different form of radiation must be causing the screen to glow. (3) As he didn't know what kind of radiation it was, he named it "X". (4) Rontgen soon started studying the new type of radiation. He designed experiments which allowed him to test how far X- rays could penetrate. He also had the bright idea of trying to take photographs with X-rays. One day, he tested his theories by asking his wife to put her hand between a photographic plate and a Crookes Tube. Sure enough, the resulting image of the bones in his wife's hand was the first ever X-ray photograph of the human body. After taking that first photograph, Rontgen understood how X-rays could benefit doctors and patients. He shared his discovery, and soon X-ray machines were appearing in hospitals. X-rays were very useful for medicine because they let doctors see a patient's bones. If a patient had a broken bone, it was made visible by the X-ray image. This let doctors know the right way to repair the fracture. Wilhelm Rontgen's accidental discovery has now been helping people for over one hundred years. Thanks to X-rays, broken bones can be repaired reliably and effectively. We should be grateful to Wilhelm Rontgen for making his discovery freely available and greatly advancing medical science. Because of this, we humans are able to live longer, healthier lives.

(1) He then placed a book between the end of the tube and the screen-the glow was still there. (2) Rontgen realized that a new and different form of radiation must be causing the screen to glow. (3) As he didn't know what kind of radiation it was, he named it "X". (4) Rontgen soon started studying the new type of radiation. He designed experiments which allowed him to test how far X- rays could penetrate. He also had the bright idea of trying to take photographs with X-rays. One day, he tested his theories by asking his wife to put her hand between a photographic plate and a Crookes Tube. Sure enough, the resulting image of the bones in his wife's hand was the first ever X-ray photograph of the human body. After taking that first photograph, Rontgen understood how X-rays could benefit doctors and patients. He shared his discovery, and soon X-ray machines were appearing in hospitals. X-rays were very useful for medicine because they let doctors see a patient's bones. If a patient had a broken bone, it was made visible by the X-ray image. This let doctors know the right way to repair the fracture. Wilhelm Rontgen's accidental discovery has now been helping people for over one hundred years. Thanks to X-rays, broken bones can be repaired reliably and effectively. We should be grateful to Wilhelm Rontgen for making his discovery freely available and greatly advancing medical science. Because of this, we humans are able to live longer, healthier lives.

Some technological developments are the results of years of diligent work. Others are stumbled upon by accident. The discovery of X-rays is in the second category. In 1895, X-ray radiation was accidentally discovered by a physicist named Wilhelm Rontgen, while he was working in his lab. Rontgen discovery greatly advanced medical science. One night in 1895, Wilhelm Rontgen was working with an electric device called a Crookes tube. A Crookes tube is a glass tube with metal components inside it. When turned on, the tube produces a stream of electrons. Rontgen and other scientists observed a new form of energy escaping from the front end of the Crookes tube. Rontgen wanted to be the first to discover this new mysterious energy. To do this, he needed to make sure the tube was covered with black cardboard.

Read the following passage and choose the best answer (A, B, C, D):
Prehistoric mammoths have been preserved in the famous tar pits of Rancho La Brea (Brea is the Spanish word for tar) in what is now the heart of Los Angeles, California. These tar pits have been known for centuries and were formerly mine for their natural asphalt, a black or brown petroleum-like substance. Thousands of tons were extracted before 1875, when it was first noticed that the tar contained fossil remains. Major excavations were undertaken that established the significance of this remarkable site. The tar pits were found to contain the remains of scores of species of animals from the last 30,000 years of the Ice Age. Since then, over 100 tons of fossils, 1.5 million from vertebrates, 2.5 million from invertebrates, have been recovered, often in densely concentrated tangled masses. The creatures found range from insects and birds to giant ground sloths, but a total of 17 proboscideans (animals with a proboscis or long nose) - including mastodons and Columbian mammoths - have been recovered, most of them from Pit 9, the deepest bone-bearing deposit, which was excavated in 1914. Most of the fossils date to between 40,000 and 10,000 years ago. The asphalt at La Brea seeps to the surface, especially in the summer, and forms shallow puddles that would often have been concealed by leaves and dust. Unwary animals would become trapped on these thin sheets of liquid asphalt, which are extremely sticky in warm weather. Stuck, the unfortunate beasts would die of exhaustion and hunger or fall prey to predators that often also became stuck. As the animals decayed, more scavengers would be attracted and caught in their turn. Carnivores greatly outnumber herbivores in the collection: for every large herbivore, there is one saber-tooth cat, a coyote, and four wolves. The fact that some bones are heavily weathered shows that some bodies remained above the surface for weeks or months. Bacteria in the asphalt itself would have consumed some of the tissues of other than bones, and the asphalt itself would dissolve what was left, at the same time impregnating and beautifully preserving the saturated bones, rendering them dark brown and shiny.

Television has transformed politics in the United States by changing the way in which information is disseminated, by altering political campaigns, and by changing citizen's patterns of response to politics. By giving citizens independent access to the candidates, television diminished the role of the political party in the selection of the major party candidates. By centering politics on the person of the candidates, television accelerated the citizen's focus on character rather than issues. Television has altered the forms of political communication as well. The messages on which most of US reply are briefer than they once were. The stump speech, a political speech given by travelling politicians and lasting 1/2 to 2 hours, which characterized nineteenth-century political discourse, has given way to the 30-second advertisement and the 10 second "sound bite" in broadcast news. Increasingly the audience for speeches is not that standing in front of the politician but rather the viewing audience tvho will hear and see a snippet of the speech on the news. In these abbreviated forms, much of what constituted the traditional political discourse of earlier ages has been lost. In 15 or 30 seconds, a peaker cannot establish the historical context that shaped the issue in question, cannot detail the probable causes of the problem, and cannot examine alternative proposals to argue that one is preferable to others. In snippets, politicians assert but do not argue. Because television is an intimate medium, speaking through it require a changed political style that was more conversational, personal, and visual than that of the old-style stump speech. Reliance on television means that increasingly our political world contains memorable pictures rather than memorable words. Schools teach US to analyze words and print. However, in a word in which politics is increasingly visual, informed citizenship requires a new set of skills. Recognizing the power of television's pictures, politicians craft televisual, staged events, called pseudo-event, designed to attract media coverage. Much of the political activity we see on television news has been crafted by politicians, their speechwriters, and their public relations advisers for televised consumption. Sound bites in news and answers to questions in debates increasingly sound like advertisements.

By centering politics on the person of the candidates, television accelerated the citizen's focus on character rather than issues. Television has altered the forms of political communication as well.
