It is hard to get a grip on food. The UN’s World Health Organisation worries about diminishing supplies and increased prices in poor countries; recent riots and near-riots in Haiti, Bangladesh and Egypt were sparked by the growing cost of wheat and rice. But, as Paul Roberts observes in "The End of Food", the developed world has lived through "a near miraculous period during which the things we ate seemed to grow only more plentiful, more secure, more nutritious, and simply better. " 46． In the second half of the 20th century, world output of corn, wheat and cereal crops more than tripled. Yet there is not enough to feed the rich, the aspirational and the poor in the world. A golden age has been transformed quite suddenly into a global crisis.Mr Roberts insists that modern agribusiness is unsustainable and becoming more so. "Precisely at the moment in history when we need to shift our system of food production into overdrive, our agricultural engine is breaking down," he says. The industry has taken cheap oil for granted. Oil fuels transportation and farm machinery, and natural gas is the basis of synthetic nitrogen production ( prices have tripled since 2002). Agriculture accounts for three- quarters of freshwater use, and water is becoming an increasingly scarce and expensive resource. Climate change makes some old assumptions about farming redundant. 47．A combination of these factors, he says, will ultimately force a complete rethinking of the way we make food.For years government subsidies held down grain prices, making food cheaper. 48．Water was also plentiful-it takes 1,000 tonnes of water to produce a tonne of grain-and an ingenious process known as Haber-Bosch makes synthetic nitrogen fertiliser easily available to grain farmers. Ruthless price-cutting at supermarkets means consumers have grown accustomed to eating too much. (In the late 19th century, Europeans already thought Americans ate three or four times more than was necessary. ) The most damaging consequence is that by 2000 31% of American adults were obese, with another 16% defined as overweight. American airlines spend $ 275 million a year more on fuel simply to lift the heavier passengers. Mr Roberts claims that every year obesity causes 400,000 premature deaths in America. Food has become as deadly as tobacco.A fruitful start would be to halve the size of portions in all American restaurants, but most consumers are reluctant rethinkers. 49．Eating organic product could be a partial solution, although one study suggests that the cost of avoiding intensive farm chemicals would mean a 31% increase in food prices. Government scientists believe that genetically modified crops might be the only way out of the crisis, but a majority of consumers are reluctant to listen.Is there a model for the future 50．Fashionably, Mr. Roberts believes that a local system based on easily obtainable seasonal foods that do not need to be transported huge distances would form part of a solution. The economics and greenery of this are far from proven. Mr Roberts can find only one country that has made "serious efforts" in this direction: Cuba, hardly a comforting example. The coming food crisis, warns the author, is as intractable as global warming, and no less urgent. 48

Marsh Cassady: Expect to be the most-hated mother in school because I will not allow my child to have a TV in his/her own room. I will also not use the TV as an electronic" babysitter" as so many parents do. It’s not my place to judge others, but I just don’t feel it is right for a child to sit and stare for horns on end when he could be playing or participating in other activities that are much more appropriate and stimulating.Benjamin Harrison: A lot of parents are not allowing their children any TV at all until they are much older. The reason is that the constant angle change of the camera produces passivity in children. They then expect life to be as "fast and change pace at the level that the TV does. There was once a cartoon where a child picks up a toy and says, "What does it do" That’s the problem with TV and young children. It steals their imaginations.Robert MacNell: TV is not that bad, but it’s not that good either. It has its pros and cons. The word here would be" Control". Got to learn how to have it in moderate amounts, and confirm the information that is gathered. I love TV because it improves my English speaking skills; it tells me different accents of different persons in different countries when speaking it. It makes me laugh sometimes. Discovery channel would be great.David Naster: Basically, I feel freer without a television in my house. I just feel there is something more natural about life without the glowing screens, and when I go several months with no exposure to TV, it feels like I have stepped out of a fishbowl. Of course, to people who watch TV ,the perception may be just the opposite — I do not live in a fishbowl because I have exiled myself from the TV culture that so many share.Adrienne Popper: I watch all types of sitcoms, news, talk shows, documentaries, etc.., in English, Spanish, and a little in German, with a notebook and a pen beside the set, taking notes OFF slang, idiomatic expressions, course words, everything teenagers ask me in the classroom (I mean in English classes ). Otherwise I wouldn’t have access to these things. We don’t have many natives at hand to help with them, books won’t bring them, so TV is my everyday assistant. Now match each of the persons ( 61. to 65) to the appropriate statement. Note: there are two extra statements. Statements[A] TV program is not helpful for the creation of children’s imagination.[B] Life without TV is freer and more natural.[C] Watching TV makes one feel relaxed.[D] Instead of watching TV, children should take part in other activities.[E] TV program is a good source of education.[F] There are advantages and disadvantages for TV.[G] TV is beneficial to child-care for mothers.

Scores of workers from MTV Networks walked off the job yesterday afternoon, filling the sidewalk outside the headquarters of its corporate parent, Viacom, to protest recent changes in benefits. The walkout highlighted the concerns of a category of workers who are sometimes called permalancers: permanent freelancers who work like full-time employees but do not receive the same benefits. Waving signs that read "Shame on Viacom," the workers, most of them in their 20s, demanded that MTV Networks reverse a plan to reduce health and dental benefits for freelancers beginning On Jan. 1st. In a statement, MTV Networks noted that its benefits program for full-time employees had also undergone changes, and it emphasized that the plan for freelancers was still highly competitive within the industry. Many freelancers receive no corporate benefits. But some of the protesters asserted that corporations were competing to see which could provide the most mediocre health care coverage. Matthew Yonda, who works at Nickelodeon, held a sign that labeled the network "Sick-elodeon. " "I’ve worked here every day for three years-I’m not a freelancer," Mr. Yonda said. "They just call us freelancers in order to bar us from getting the same benefits as employees. " The changes to the benefits package were announced last Tuesday. Freelancers were told that they would become eligible for benefits after 160 days of work, beginning in January. While that eased previous eligibility rules, which required freelancers to work for 52 weeks before becoming eligible, it would have required all freelancers not yet eligible for benefits to start the waiting period over again on Jan. 1st. The 401 (k) plan was also removed. On Thursday, acknowledging the complaints, MTV Networks reinstated the 401 (k) plan and said freelancers who had worked consistently since March would be eligible. Fueled by a series of blog posts on the media Web site Gawker-the first post was headlined "The Viacom Permalance Slave System"-a loose cohort of freelancers created protest stickers and distributed walkout fliers last week. Caroline O’Hare, a unit manager who has worked for MTV for more than two years, said the new health care plan-with higher deductibles and a $ 2,000 cap on hospital expenses each year-had provoked outrage. "They think they can treat us like children that don’t have families, mortgages or dreams of retirement," she said. Outside Viacom’s headquarters, several workers held posters with the words, "There’s too many of us to ignore. " It was unclear how many freelancers are on the company’s payroll; an MTV Networks’ spokeswoman said the figure was not known because it rises and falls throughout the year. The company has 5,500 full-time employees, excluding freelancers, around the world. Two freelancers and one full-time employee, who asked not to be identified for fear of retribution, estimated that the percentage of freelancers in some departments exceeded 75 percent. Another labor action is expected to take place outside Viacom later this week. Members of the Writers Guild of America, who have been on strike for five weeks, are expected to picket there on Thursday. Which of the following is NOT true according to the text
Remember Second Life, the virtual world that was supposed to become almost as important as the first one Now populated by no more than 84,000 avatars at a time, it has turned out to be a prime example of how short-lived Internet fads can be. Yet if many adults seem to have given up on virtual worlds, those that cater to children and teenagers are thriving. Several have even found a way to make money. In America, nearly 10 million children and teenagers visit virtual worlds regularly, estimates eMarketer, a market researcher-a number the firm expects to increase to 15 million by 2013．As in January, there were 112 virtual worlds designed for under-18s with another 81 in development, according to Engage Digital Media, a market research firm. All cater to different age groups and tastes. In Club Penguin, the market leader, which was bought by Disney in 2007 for a whopping $ 700 million, primary-school children can take on a penguin persona, fit out their own igloo and play games. Habbo Hotel, a service run from Finland, is a global hangout for teenagers who want to customise their own rooms and meet in public places to attend events. Gala Online, based in Silicon Valley, offers similar activities, but is visited mostly by older teens who are into Manga comics. Not a hit with advertisers, these online worlds earn most of their money from the sale of virtual goods, such as items to spruce up an avatar or a private room. They are paid for in a private currency, which members earn by participating in various activities, trading items or buying them with real dollars. This sort of stealth tax seems to work. At Gala Online, users spend more than $1 million per month on virtual items, says Craig Sherman, the firm’s chief executive. Running such a virtual economy is not easy, which is why Gaia has hired a full-time economist to grapple with problems that are well known in the real world, such as inflation and an unequal distribution of wealth. There are other barriers that could limit the growth of virtual worlds for the young, but the main one is parents. Many do not want their offspring roaming virtual worlds, either because they are too commercial or are thought to be too dangerous. Keeping them safe is one of the biggest running costs, because their sponsors have to employ real people to police their realms. Youngsters are also a fickle bunch, says Simon Levene of Accel Partners, a venture- capital firm. Just as children move from one toy to another, they readily switch worlds or social networks, often without saying goodbye. Even so, Debra Aho Williamson, an analyst at eMarketer, believes "these worlds are a training ground for the three-dimensional web". If virtual worlds for adults, which so far have been able to retain only hardcore users, manage to hang on for a few years, they may yet have a second life. In the first paragraph it says that "Several have even found a way to make money" Which of the following could possibly be the "way"
