Article: Televisiozn ---- that most widespread and persuasive of modern technologies, marked by rapid change and growth ---- is moving into a new era, an era of extraordinary advancement and diversity, which promises to reshape our lives and our world. It is an electronic revolution, made possible by the marriage of television and computer technologies. The word 'television', coming from its Greek ( tele: distant) and Latin ( vision: sight) roots, can literally be interpreted as sight from a distance. , it works in this way: through an advanced system of electronics, television provides the capability of changing an image ( focused on a special photoconductive plate within a camera ) into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reorganized into that same image. Television is more than just an electronics system, however. It is a means of expression, as well as a tool for communication, and as such becomes a powerful tool for reaching other human beings. The field of television can be divided into two categories determined by its means of transmission(,). First, there is broadcast television, which reaches the masses through airwave transmission of television signals. Second, there is nonbroadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques. Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us for about thirty-seven years in a form similar to that exists today. During those years, it has been controlled, for the most part, by the broadcast networks, ABC, NBC, and CBS, who have been the major providers of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our understanding of it as well. We have come to look upon the picture tube as a source of entertainment, placing our role in this dynamic...

Read the following article and select the best answer. Article: As China becomes increasingly urbanized , it has to find space for its urban and rural citizens as both groups become increasingly integrated. Experts suggest a possible model way may be "re-inventing" a "garden city". China's mega-cities are bursting at the borders and the country is now undergoing the quickest and biggest urbanization in the history of mankind. It is estimated that by 2025, China will have 400 million more people living in its cities, raising its urban population to 900 million. Besides, new satellite towns are mushrooming on the urban fringes while city ring roads are rippling outwards into the countryside at amazing speed. Satellite maps collected by Professor Joshua Bolchover at the University of Hong Kong bring the problem sharply into focus. They track the changing rural-urban framework in the past 30 years, and suggest that cities are cruelly destroying surrounding rural land and rapidly reducing the amount of arable land, which gives way to new residential blocks, new industrial zones, new financial centers and the other inevitable signs and signatures of economic growth. This, however, is not sustainable growth pattern, especially when China has the world's largest population to feed. So concerned urban planners are starting to note the social and physical effects of diaspora when replaced rural communities are forced into the cities. On the other hand, a trend of thought is gradually taking shape and this is the concept of the "garden city", a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a long-term study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education. The concept is... Question: In Hua Li's opinion, a combination of country and city will _ . - benefit the environment and lower living costs - become a project that needs a long-term study - lead to more rural communities being replaced - attract more farmers to take tours in cities
benefit the environment and lower living costs

Read the following article and select the best answer. Article: Emily and her boyfriend had just had a fight. She felt alone and hopeless. Then she went into the kitchen and grabbed what she needed before going back up to her room quietly. She switched on the TV and started eating...and eating...for hours, until it was all gone. What Emily didn't know at the time was that she was suffering from an illness called binge-eating disorder(BED) . For years, Emily didn't tell anyone what she was doing. She felt ashamed, alone, and out of control. Why don't famous people confess to BED, as they do to _ ? It's simple: There's a stigma involved. "Overeating is seen as very bad, but dieting to be skinny is seen as positive and even associated with determination," says Charles Sophy, a doctor in Beverly Hills , California. "Some parents or friends may look at a teen with BED and think, 'Oh, a good diet and some will-power will do the trick.' But that's not true," says Dr.Ovidio Bermudez , a baby doctor at the Eating Recovery Center in Denver. "Eating disorders are real physical and mental health issues; it's not about willpower." The focus in treating BED shouldn't be on weight, because as with all eating disorders, the behaviors with food are a symptom of something deeper. Like most other diseases, genetics may play a big part in who gets BED and who doesn't. If you have a close relative with an eating disorder, that means you're more likely to develop an eating disorder of your own. Besides, many people with BED have tried at some point or another to control it by going on a diet, but paying more attention to food doesn't help. And it might even make things worse, like it did for Carla, who's 15 now and is recovering from BED. "My parents would always tease me about my weight, so when I was 14, I went on a very restrictive diet," she says. When you can't have something, you only want it more, so every time Carla would have a bite of something that wasn't allowed on her strict diet. She would quickly lose control and binge . Question: What can we learn from Carla's story? - BED is an incurable disease. - BED has something to do with genes. - Going on a diet won't help BED patients. - BED patients should pay attention to their food.
Going on a diet won't help BED patients.
