[EX Q]: Article: Musa Kayairanga of Rwanda is a traditional healer. He uses natural medicines to treat his patients. He learned how to use computers at a rural telecommunications center in his country. Musa Kayairanga says he exchanges information with doctors as far away as Canada. He also says the computer has improved his knowledge of using plants to treat diseases. Many people in rural areas are now able to communicate with the rest of the world. This is one example of how technology is changing life in developing countries. Andrew Burns is an economist at the World Bank in Washington, D.C. He led a recent study of technology in developing countries. The study found that technology has spread faster in such countries than in rich nations. It also found that technological progress has helped raise wages in developing countries. And it reduced the percentage of people living in extreme poverty from twenty-nine percent in 1990 to eighteen percent in 2004. Progress in communications technology has aided the growth of call centers in developing countries. Call centers are offices where most telephone calls for a business can be answered. For example, a woman in the United States who calls her computer company about a problem might speak with someone in India or Pakistan. Call centers serve businesses in local and international markets. And they have added to economic growth by providing well-paid jobs and new skills for workers who might not have had such employment. Ahsan Saeed is a young call center worker in Karachi, Pakistan. He says the job improves his language skills, his sales skills and his ability to deal with people.( from VOA Special English )

[EX Q]: Article: Sir, The majority(=Most) of your readers must have been surprised and shocked to read a letter from Mr.R.Hogg,published in last Wednesday's Herald.Mr.Hogg seems to think that his own convenience and that of motorists in general are the only things that matter in our city. I would have supported Mr.Hogg if he had just made suggestions to improve the situation.No doubt his problems would be partly solved if the local government built a multi-storey car park in the city center,instead of encouraging motorists to use public transport.All the same,judging from the tone of Mr.Hogg's letter,I suspect that motorists who are so careless of pedestrians' safety that they would rather park their ears on the pavement than hold up the traffic would probably be too lazy to use a multi-storey car park if they had to walk a few hundred yards to their destination afterwards. My main reason for writing,however,is much more important.Does Mr.Hogg realize that,according to figures showed by the Department of Transport,13,000 people were knocked down in Britain last year because of ears being illegally parked either on the pavement or on crossings? In fact,although the total pedestrian casualty rate has fallen over the last ten years,there has been an increase in accidents caused when pedestrians have to step out into the mad to avoid parked cars on the pavement and cannot see oncoming traffic. I cannot share Mr.Hogg's view that the government have paid little attention to"long-suffering motorists":and I think the punishment for dangerous parking should be made severe enough to stop all motorists from breaking the law in this way.

[EX Q]: Article: All around the world, shoppers flock to Wal-Mart to buy everything. In Texas, they come for another reason: to see the wind turbine , which supplies 5% of the store's electricity. It along with other facilities, such as exterior walls coated with heat-reflective paint, makes this Wal-Mart a green giant. The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods. It throws its weight behind environmental responsibility, and the impact could be amazing. "One little change in product packaging could save 1, 500 trees," says Wal-Mart CEO Lee Scott."If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference." Scott wants Wal-Mart to do its part too. He has promised to cut the existing greenhouse-gas emissions over the next few years and promised to construct new stores that are more efficient. He wants Wal-Mart's fleet of more than 7, 000 trucks to get twice as many miles per gallon by 2015. Factories that show Wal-Mart they're cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it's working with consumer-product manufacturers to reduce their packaging and will reward them if they do so. Some people may doubt it is a bid to attract attention from Wal-Mart's controversial labor and health-insurance practices. But it's not just window dressing, because Wal-Mart sees profits in going green. Scott says, " _ . We don't go where we don't think there's a great interest in change." Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart's image at a time when his company's reputation is declining. He acknowledges that he launched the plan partly to shield Wal-Mart from bad press about its contribution to global warming. "By doing what we're doing today, we avoid the headline risks that are going to come for people who did not do anything," he says. "At some point businesses will be held responsible for the action they take." Meanwhile, should Wal-Mart succeed at shrinking its environmental footprint and lowering prices for green products, both the planet and the company will profit.
