单选题{{B}}Passage Three{{/B}} Is Wal-Mart going wobbly? Over the past couple of weeks, America's largest company--linchpin of the low-wage, no-benefit economy that is increasingly the norm in America--has announced some surprising reversals of course. In a series of speeches and interviews, chief executive H. Lee Scott unveiled four initiatives that he clearly hopes will polish the company's increasingly tarnished image. Wal-Mart, he said, will shift to more environmentally responsible practices--demanding better packaging of its products. It will offer more affordable health insurance to its employees, cutting the monthly premium in some cases to just ＄11. It will monitor the environmental and health and safety practices of its foreign suppliers. And it will lobby for a higher federal minimum wage. Scott's timing is anything but accidental. The sweatshop conditions in which thou-sands of employees of Wal-Mart's suppliers routinely work, and the depressive effect that Wal-Mart has on working-class living standards here in the United States, are receiving increasing scrutiny--enough to impede the company's growth. Wal-Mart's at-tempts to open stores in the major cities of the Northeast and West Coast have been largely checked by a coalition of fearful and irate unions, smaller retailers, churches and liberal activists. Wal-Mart's stock is down 13 percent this year. And worse is still to come. So the leopard realized it was time to change its spots-up to a point. Only 44 percent of Wal-Mart's nearly 1. 3 million U.S. employees are covered under its health insurance plan. Now the company says it will make its insurance more affordable. Of all Scott's commitments, the one that does merit belief is his out-of-the-blue declaration of support for a higher minimum wage. For Wal-Mart is bumping up against a serious problem at least partly of its own making: Because it pitches its products to a disproportionately low-income client, its revenue rises and falls with the fortunes of the lower end of the American working class. And those fortunes these days are anything but bright. The coming crunch in heating oil prices, the decimation of American manufacturing, the steady decline of median family incomes over the past several years, the failure to raise the federal minimum wage since 1997--all these are combining to limit the ability of Wal-Mart shoppers to buy as much as they used to. Wal-Mart, could, of course, raise its workers' wages, but Scott has dismissed that out of hand. So now it's the feds' responsibility to rescue Wal-Mart from the consequences of the low-wage, low-consumption economy that Wal-Mart, with such fanatical devotion, has created. For, in Wal-Mart's America, it's not clear that even Wal-Mart can thrive.

单选题People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 21 problem. They often accept the opinion or ideas of other people. Other times they begin to act without (22) ; they try to find a solution by trial and error. However, when all of these methods (23) , the person with a problem has to start analysing. There are six (24) in analysing a problem. (25) , the person must recognize that there is a problem. For example, Sam' s bicycle is broken, and he cannot ride it to class as he usually does. Sam must (26) that there is a problem with his bicycle. Next the person must (27) the problem. Before Sam can repair his bicycle, he must know why it does not work.

(32) , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully. After (33) the problem, the person should have several suggestions for a possible solution. Take Sam as an example (34) , his suggestions might be tighten or loosen the brakes; buy new brakes and change the old ones. In the end, one (35) seems to be the solution to the problem. Sometimes the final idea comes quite unexpectedly because the thinker suddenly sees something in a different way. Finally the solution is tested. Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

单选题 The technology revolution may be coming to poor countries via the mobile phone, not the personal computer, as it did in rich ones. And just as the Internet encouraged an entrepreneurial philosophy, and with it the creation of a few too many dotcom firms, Africa's surge in mobile-phone use may {{U}}unleash{{/U}} the same sort of business energy, but tailored to local needs. One such initiative is about to begin. TradeNet, a software company based in Accra, Ghana, will unveil a simple sort of eBay for agricultural products across a dozen countries in West Africa. It lets buyers and sellers indicate what they are after and their contact information, which is sent to all relevant subscribers as an SMS text message in one of four languages. Interested parties can then reach others directly to do a deal. Listing offers is free, as is receiving the texts. TradeNet plans to earn revenue by putting advertisements in the messages, though it hopes the service will become so useful that recipients will eventually want to pay. For the moment, though, the company is busy signing up users and swallowing the cost of sending the messages. Mobile-phone use in sub-Saharan Africa is soaring. Whereas only 10% of the population had network coverage in 1999, today more than 60% have it, a figure expected to exceed 85% in the coming year, according to the GSM Association, an industry trade group. This provides the infrastructure for businesses like TradeNet to function. TradeNet is the brainchild of Mark Davies, a British dotcom tycoon who gave up the rat race and went to Africa in 2000. In 2005, he started the prototype for TradeNet using around ＄600,000 of his own money and about ＄200,000 from aid agencies. An early set of trials last year generated a surplus of trades, such as a sale of organic fertilizer between a person in Yemen and another in Nigeria. A number of other mobile-phone market-places taking shape also started as aid projects. For example, Trade at Hand, a project funded by the UN's International Trade Centre in Geneva, provides daily price information for fruit and vegetable exports in Burkina Faso and Mali, with plans to add more countries. And Manobi, a telecoms firm based in Senegal, providing real-time agricultural and fish prices to fee-paying subscribers, is also backed by aid money. But TradeNet's approach is unique so far because it collects valuable economic data-names, locations, business interests and telephone numbers-and then sells them to advertisers. The price of economic development may be junk mail by mobile phone.
