After too long on the Net, even a phone call can be a shock. My boyfriend’s Liverpudlian accent suddenly becomes difficult to understand after the (S1) of his words on screen; a secretary’s tone seems more rejecting than I’d (S2) it would be. Time itself becomes fluid-hours become minutes, and alternately seconds stretch into days. Weekends, once a (S3) of my week, are now just two ordinary days. For the last three years, since I stopped working as a (S4) for Charlie Rose, I have done much of my work as a telecommuter. I submit articles and edit them via E-mail and (S5) with colleagues on Internet mailing lists. My boyfriend lives in England; so much of our relationship is (S6) . If I desired, I could stay inside for weeks without wanting anything. I can order food, and (S7) my money, love and work. In fact, at times I have spent as long as three weeks alone at home,going out only to get mail and buy newspapers and groceries. I watched most of the blizzard of ’96 on TV.(S8) . I start to feel as though I’ve merged with my machines, taking data in, spitting them back out, just another mode on the Net. Other on line reports the same symptoms. We start to strongly dislike the outside forms of socializing. It’s like attending an A. A. meeting in a bar with everyone holding a half- sipped drink. We have become the Net opponents’ worst nightmare. What first seemed like a luxury, crawling from bed to computer, not worrying about hair, and clothes and face, has become an avoidance, a lack of discipline. (S9) ,coming back out of the cave can be quite difficult. (S10) . The voices of the programs soothe me,but then I’m jarred by’the commercials. I find myself sucked in by soap operas, or compulsively needing to keep up with the latest news and the weather. "Dateline", "Frontline", "Nightline", CNN, New York 1,every possible angle of every story over and over and over, even when they are of no possible use to us . Work moves from foreground to background. S3
Many people consider the wider use of biofuels a promising way of reducing the amount of surplus carbon dioxide (CO2) being pumped into the air by the world’s mechanized transport. The theory is that plants such as sugar cane, maize (corn, to Americans), oilseed rape and wheat take up CO2 during their growth, so burning fuels made from them should have no net effect on the amount of that gas in the atmosphere.Theory, though, does not always translate into practice, and just as governments have committed themselves to the greater use of biofuels, questions are being raised about how green this form of energy really is. The latest comes from the International Council for Science (ICSU) based in Paris.The ICSU report concludes that, so far, the production of biofuels has aggravated rather than ameliorated global warming. In particular, it supports some controversial findings published in 2007 by Paul Crutzen of the Max Planck Institute for Chemistry in Germany. Dr. Crutzen concluded that most analyses had underestimated the importance to global warming of a gas called nitrous oxide (N2O). The amount of this gas released by farming biofuel crops such as maize and rape probably negates by itself any advantage offered by reduced emissions of CO2.Although N2O is not common in the Earth’s atmosphere, it is a more potent greenhouse gas than CO2 and it hangs around longer. The result is that, over the course of a century, its ability to warm the planet is almost 300 times that of an equivalent mass of CO2.N2O is made by bacteria that live in soil and water and, these days, their raw material is often the nitrogen-rich fertiliser that modern farming requires. Since the 1960s the amount of fertiliser used by farmers has increased sixfold, and not all of that extra nitrogen ends up in their crops. Maize, in particular, is described by experts in the field as a “nitrogen-leaky” plant because it has shallow roots and takes up nitrogen for only a few months of the year. This would make maize (which is one of the main sources of biofuel) a particularly bad contributor to global N2O emissions.But it is not just biofuels that are to blame. The ICSU report suggests N2O emissions in general are probably more important than had been realised. Previous studies, including those by the International Panel on Climate Change (IPCC), a United Nations-appointed body of experts, may have miscalculated their significance — and according to Adrian Williams of Cranfield University, in Britain, even the IPCC’s approach suggests that the global-warming potential of most of Britain’s annual crops is dominated by N2O emissions. What does the word “potent” (Line 1, Para. 4) probably mean（）
