Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.
Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.
Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.
The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.

EAT YOUR VEGETABLES.　Wash your hands.　Always say "please"　and　"thank you　".We are full of advice for our children,　but when it comes to money,　we often have little to say.　As a result,　our children may grow up with clean hands and good manners,　but without any idea how to　manage their money.Here are some basics that will help guide them their entire lives：

Show them the future.　If your 13-year-old girl were to save $1.000,invest(投资)it at 8% and add $100 every month,　by the time she's 65,she would have $980,983!zxxk

Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history,　but they must be used responsibly,　which means paying off your debt in time.　Explain to your children that when you buy something using a credit card,　you can easily end up paying two or three times what you would have paid if you used cash.

Teach patience.　Suppose your child wants a new bicycle that costs $150.Rather than paying the cash,　give him some regular pocket money and explain that by putting aside,say,$15 each week,　he will be able to buy it for himself in only ten weeks.

Provide incentive.　Tell your children the importance of saving.　"For every dollar he or she agrees to save and invest rather than spend,　you agree to add another dollar to the pot,　"says Cathy Pareto,　expert in money planning.

Explain your values.　Values and money are deeply intertwined(缠结在一起),　says 　Eilleen 　Gallo,　co-author of The Financially Intelligent Parent.　When your child demands that you buy something,　explain why you really don't want to buy it.　"You might say, 'I'd rather save that money for your education,'"　advises Gallo.　Every time you spend or don't spend money,　you have a chance to share your values.

    The link between environment and poverty is central to that great race for sustainability. It is a pity, then, that several powerful fallacies (谬论) keep getting in the way of sensible debate. One popular myth is that trade and economic growth make poor countries' environmental problems worse: Growth, it is said, brings with it urbanization, higher energy consumption and industrialization —all factors that contribute to pollution and pose health risks.

    Another common view is that poor countries should pollute now and clean up later. Certainly poor countries should not be made to adopt American or European environmental standards. But there is evidence to suggest that poor countries can and should try to tackle some environmental problems now, rather than wait till they have become richer.

    One powerful—and until recently ignored—weapon in the fight for a better environment is local people. Much academic research has shown that the poor are often victims of resource depletion (损耗) : it tends to be rich locals or outsiders who are  responsible for the worst exploitation (开发). Local people usually have a better knowledge of local ecological conditions than experts in faraway capitals, as well as a direct interest in improving the quality of life in their village.
