单选题A few years ago, when environmentalists in Washington State began agitating to rid local dumps of toxic old computers and televisions, they found an unexpected ally: Hewlett-Packard Co. Teaming up with greens and retailers, hp took on IBM, Apple Computer, and several major TV manufacturers, which were resisting recycling programs because of the costs. Aided by hp's energetic lobbying, the greens persuaded state lawmakers to adopt a landmark program that forces electronics companies to foot the bill for recycling their old equipment. "This bill puts our market-based economy to work for the environment," said Washington Governor Christine O. Gregoire as she signed the plan into law on Mar 24. The movement to recycle electronic refuse, or "e-waste," is spreading across the nation, and so is hp's clout. The company helped the greens win a big battle in Maine, In 2004 when the state passed the nation's first e-waste "take-back" law. Washington followed suit. Now, Minnesota and New Jersey are preparing to act, and 19 other states are weighing legislation. Activists hope to banish high-tech junk from landfills and scrub the nation's air and water of lead, chromium, mercury, and other toxins prevalent in digital debris, hp's efforts have made it the darling of environmentalists. They say take-back laws are more effective at getting digital junk recycled than point-of-sale fees, which tax consumer electronics products to fund state-run recycling programs. They're also pleased because effective programs in the U. S. reduce the likelihood that the products will be shipped to less developed countries and disassembled under unsafe conditions. But hp's agenda isn't entirely altruistic. Take-back laws play to the company's strategic strengths. For decades the computer maker has invested in recycling infrastructure, a move that has lowered its production costs, given it a leg up in the secondary market for equipment, and allowed it to build a customer service out of "asset management," which includes protection of dam that might remain on discarded gear. In 2005, hp recycled more than 70 000 tons of product, the equivalent of about 10% of company sales and a 15% increase from the year before. And it collected more than 2.5 million units (in excess of 25 000 tons) of hardware to be refurbished for resale or donation. No other electronics maker has a resale business on this scale. But the others may soon wish to emulate hp. "We see legislation coming," says David Lear, hp's vice-president for corporate, social, and environmental responsibility. "A lot of companies haven't stepped up to the plate.... If we do this right, it becomes an advantage to us./

单选题TEXT B A closer observer of the small screen once called it a "vast wasteland of violence, sadism and murder, private eyes, gangsters and more violence-and cartoons." That is how Newton Minow, a US television regulator, described it in 1961. Since then television language has become more colourful, violence more explicit and sex more prevalent. Lady Chatterley's Lover has moved from the banned book shelf to a classic BBC serial. Concern over such changing standards has shaped our view of television and masked its broader influence in developing countries. To illustrate its effects, Kenny cites the case of Brazil. When television there began to show a steady diet of local soaps in the 1970s, Brazilian women typically had five or more children and were trapped in poverty. As the popularity of the soaps grew, birth rates fell. According to researchers, 72% of the leading female characters in the main soaps had no children and only 7% had more than one. One study calculated that such soaps had the same effect on fertility rates as keeping girls in school for five years more than normal. It is not just birth rates that are affected. Kenny notes: "Kids who watch TV out of school, according to a World Bank survey of young people in the shanty towns of Fortaleza in Brazil, are considerably less likely to consume drugs." Television appears to have more power to reduce youth drug use than the strictures of an educated mother and Brazilian soaps presenting educated urban women running their own businesses are thought to be compelling role models. Television can also improve health, In Ghana a soap opera line that warned mothers they were feeding their children "more than just rice" if they did not wash their hands after defecating was followed by a seemingly permanent improvement in personal hygiene. Why do such changes happen? Simple, says Kenny: soap operas, whether local versions of Ugly Betty or vintage imports of Baywatch, open up new horizons. "Some hours could he better spout planting trees, helping old ladies across the road or playing cricket," he said. "But watching TV exposes people to new ideas and different people. With that will come greater opportunity, growing equality and a better understanding of the world. Not bad./

单选题If by any chance someone comes to see me, ask them to leave a______.

单选题A young student like him cannot have ______.

单选题What do we mean by a satisfactory standard of living? Obviously, it must include the basic necessities of life such as food, clothing and shelter. To get these necessities on regular basis, a person must have a reliable income. But we have other needs which would probably also be included as basic, such as health and education facilities. We may think of all of these as our needs. Yet most of us would be far from satisfied if we had nothing more than these which are supplied for us. We all enjoy extra income to spend on things like books, sports or hobbies. Sometimes we save some of this extra income to pay for future expense of this type on holidays. So we must add our wants to our basic needs. Our standard of living is the degree, to which these needs and wants are satisfied. But as time goes on, what we think of as our basic needs change. Twenty years ago a television would have been a luxury, and still is in many countries now. Even now we cannot say it is a need in the same sense as food, clothing and shelter. Yet if most of the people of a country have one, it comes to be accepted as a need. It is possible therefore to have food, clothing and shelter and still be poor by the standards of our own society.

单选题Society can be broken up into three classes: the Elite, the Meek and the Masses. The Elite are (51) of the top 10% of society, those that don't need anyone's help (52) it comes to getting what they want. They have the status, the money, the power, and the respect to (53) whatever they need. In spite of the fact that they enjoy the upper hand, people outside of this class will still go to great (54) to help them even further. The Meek are comprised of the bottom 10% of society, those who need our help, and badly at that. But (55) so many of us are eager to get in well with the Elite, few actually care enough to provide any (56) to the Meek. The Masses are the largest class, (57) up the middle 80% between the Meek and the Elite. Most of the Masses could use some help getting by, and (58) it would usually improve their lives considerably, but they (59) get it. Why do most people would rather help the Meek or the Elite? Because they are (60) with instant gratification or the anticipation of future benefits. We rarely help the Masses because there is nothing really in it for us, and this shows humanity's true colors.
