单选题Coming Soon to a Theater Near You! What are special effects? Do you enjoy movies that use a lot of special effects Dinosaurs(恐龙) from the distant past! Space battles from the distant future! There has been a revolution in special effects, and it has transformed the movies we see. The revolution began in the mid 1970s with George Lucas"s Star Wars, a film that stunned (使震惊) audiences. That revolution continues to the present, with dramatic changes in special-effects technology. The company behind these changes is Lucas"s Industrial Light & Magic (ILM). And the man behind the company is Dennis Muren, who has worked with Lucas since Star Wars. Muren"s interest in special effects began very early. At the age of 6, he was photographing toy dinosaurs and spaceships. At 10, he had an 8 millimeter movie camera and was making these things move through stop-motion. (Stop-motion is a process in which objects are shot with a camera, moved slightly, shot again, and so on. When the shots are put together, the objects appear to move.) Talk to Muren and you"ll understand what ILM is all about: taking on new challenges. By 1989, Muren decided he had pushed the old technology as far as it would go. He saw computer graphics (图像) (CG) technology as the wave of the future and took a year off to master it. With CG technology, images can be scanned into a computer for processing, for example, and many separate shots can be combined into a single image. CG technology has now reached the point, Muren says, where special effects can be used to do just about anything so that movies can tell stories better than ever before. The huge success of Jurassic Park and its sequel (续集), The Lost World, the stars of which were computer-generated dinosaurs, suggests that this may very well be true.

单选题 {{B}}What is Market?{{/B}} The word market is used in a number of ways. There is a stock market and automobile market, a retail market for furniture and a wholesale market for furniture. One person may be going to the market; another may plan to market a product. What, then is a market? A market may be defined as a place where buyers and sellers meet, goods or services are offered for sale, and transfers of ownership occur. A market may also be defined as the demand made by a certain group of potential buyers for a good or service. For instance, there is a farm market for petroleum products. The terms market and demand are often used interchangeably; they, may also be used jointly as market demand. These definitions are not sufficiently precise to be useful to us here. For business purposes we define a market as people or organizations with wants (needs) to satisfy, money to spend, and the willingness to spend it. Thus in the market demand for any given product or service, there are three factors to consider — people or organizations with wants (needs), their purchasing power, and their buying behavior. We shall employ the dictionary definition of needs: the lack of anything that is required, desired, or useful. We do not limit needs to the narrow physiological requirements of food, clothing and shelter essential for survival. In our discussion the words and wants are used synonymously and interchangeably. In a strict interpretation, however, needs would refer to such basic physiological requirements as food, clothing, and shelter, while wants would be such basic preferences. However, in our affluent society, little is to be gained by trying to differentiate between the two. Many of us would see as needs some items that are far beyond food, clothing, and shelter.

单选题Study Helps Predict Big Mediterranean Quake Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365. Using radiocarbon dating techniques, simulations and computer models, the researchers recreated the ancient disaster in order to identify the responsible fault. "We are saying there is probably a repeat time of 800 years for this kind of earthquake," said Ms. Beth Shaw, an earthquake scientist at the University of Cambridge, who led the study. Scientists study past earthquakes in order to determine the future possibility of similar large shocks. "Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region," Ms. Shaw said. "The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1,300, which means the next powerful one could come in the next 100 years," she added in a telephone interview. Ms. Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion, she said. Their computer model suggested an 8 magnitude quake on the fault would produce a tsunami that floods the coastal regions of Alexandria and North Africa, the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik. "This would he similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta, likely killing tens of thousands of people," she said.

单选题 What Is Globalization? It was the anti-globalization movement that really put globalization on the map. As a word it has existed since the 1960s, but the protests against this allegedly new process, which its opponents condemn as a way of ordering people's lives, brought globalization out of the financial and academic worlds and into everyday current affairs. In the late 1980s and early 1990s, the business model called the "globalize" financial market came to be seen as an entity that could have more than just an economic impact on the parts of the world it touched. Globalization came to be seen as more than simply a way of doing business, or running financial markets--it became a process. From then on the word took on a life of its own. So how does the globalize market work? It is modern communications that make it possible; for the British service sector to deal with its customers through a call centre in India, or for a sportswear (运动服) manufacturer to design its products in Europe, make them in southeast Asia and sell them in north America. But this is where the anti-globalization side gets stuck in (关注). If these practices replace domestic economic life with an economy that is heavily influenced or controlled from overseas. Then the creation of a globalize economic model and the process of globalization can also be seen as a surrender of power to the corporations, or a means of keeping poorer nations in their place. Not everyone agrees that globalization is necessarily evil, or that globalize corporations are running the lives of individuals or are more powerful than nations. Some say that the spread of globalization, free markets and free trade into the developing world is the best way to beat poverty the only problem is that free markets and free trade do not yet truly exist. Globalization can be seen as a positive, negative or even marginal process. And regardless of whether it works for good or ill, globalization's exact meaning will continue to be the subject of debate among those who oppose, support or simply observe it.

单选题The No Child Left Behind Act pushed by President George W. Bush unintentionally exacerbated the problem. It required each state to ensure that its students achieve" universal proficiency" in reading and math—but allowed each to define what that meant. The result was that many states made their job easier by setting their bar lower. This race to the bottom resulted in a Lake Wobegon world where every state declared that its kids were better than average. Take the amazing case of Mississippi. According to the standards it set for itself,89% of its fourth - graders were proficient or better in reading, making them the best in the nation. Yet according to the random sampling done every few years by the National Assessment of Educational Progress (NAEP) test, a mere 18 % of the state's fourth- graders were proficient, making them the worst in the nation. Even in Lake Wobegon that doesn't happen. Only in America. The ThomasB. Fordham Institute, led by reformer Chester Finn Jr. , has been analyzing state standards for more than a decade and concludes, "Two - thirds of U. S. children attend schools in states with mediocre standards or worse.
