It's no secret that the world has become a very fastpaced place. Free time has been replaced by cyber (网络的) time to the point where my family feels the need to comment on my presence at the dinner table. With all these options and distractions (使人分心的事) it can be hard to spend quality time with the people you love. My Dad and I have always worked around this. Over years we've learned how to watch in silence while enjoying each other's company and by now we know what to comment on during the commercials. Once we were watching one of our favourite shows. At the commercial he turned to me and asked if I liked going to school. I thought about the question for a few moments before admitting that I did. "Do you look forward to going?" This question seemed easier to answer, but I thought it over. "Not all the time. Sometimes, there are classes that I dread. But then there are people I want to see or things I want to do, so I guess it evens out." Dad nodded. "You see these characters on the show? They like going to work. They look forward to it. They are so idealistic that they go to work every day, believing they can change the world. That's why we like to watch them." I thought about what he was saying. "Do you look forward to going to work?" I asked. Dad paused. "I honestly don't think about it. It's not something I anticipate or dread. It's just something that I do. I always looked forward to going to school, though. I wanted to learn. Now that I think about it, when I first started working I did look forward to it. That's what's important. Do something that you enjoy doing. Do something that you will look forward to. Otherwise, what's the point?" Now I have learned that sometimes it's not the length of the talk that's important but what's said during the talk. It is still possible to have quality time during a commercial break. |

Claims of a "water apartheid," where poor people pay more for water than the rich, are bound to attract attention. But what are the economics behind the problem, and how can it be fixed? In countries that have trouble delivering clean water to their people, a lack of infrastructure is often the culprit. People in areas that are not served by public utilities have to rely on costlier ways of getting water, such as itinerant water trucks and treks to wells. Paradoxically, as the water sources get costlier, the water itself tends to be more dangerous. Water piped by utilities - to the rich and the poor alike - is usually cleaner than water trucked in or collected from an outdoor tank.
The problem exists not only in rural areas but even in big cities, said Hakan Bjorkman, program director of the UN agency in Thailand. Further, subsidies made tolocal water systems often end up benefiting people other than the poor, he added.
The agency proposes a three-step solution. First, make access to 20 liters, or 5 gallons, of clean water a day a human right. Next, make local governments accountable for delivering this service. Last, invest in infrastructure to link people to water mains.The report says governments, especially in developing countries, should spend at least 1 percent of gross domestic product on water and sanitation. It also recommends that foreign aid be more directed toward these problems. Clearly, this approach relies heavily on government intervention, something Bjorkman readily acknowledged. But there are some market-based approaches as well.
By offering cut-rate connections to poor people to the water mainline, the private water utility in Abidjan, Ivory Coast, has steadily increased access to clean water, according to the agency&39;s report. A subsidy may not even be necessary, despite the agency&39;s proposals, if a country can harness the economic benefits of providing clean water.
People who receive clean water are much less likely to die from water-borne diseases - a common malady in the developing world - and much more likely to enjoy long, productive, taxpaying lives that can benefit their host countries. So if a government is trying to raise financing to invest in new infrastructure, it might find receptive ears in private credit markets - as long as it can harness the return. Similarly, private companies may calculate that it is worth bringing clean water to an area if its residents are willing to pay back the investment over many years.
In the meantime, some local solutions are being found. In Thailand, Bjorkman said, some small communities are taking challenges like water access upon themselves. "People organize themselves in groups to leverage what little resources they have to help their communities," he said. "That&39;s especially true out in the rural areas. They invest their money in revolving funds and saving schemes, and they invest themselves to improve their villages. "It is not always easy to take these solutions and replicate them in other countries, though. Assembling a broad menu of different approaches can be the first step in finding the right solution for a given region or country.

In the(3)that von Neumann proposed, the basic instruction cycle is for the processor to fetch the instruction pointed at by the program counter,(4)the program counter, and then execute the instruction. Because instructions are executed strictly sequentially, there is little inherent parallelism, and(5)opportunity to employ large numbers of processors to gain speed.
