Scientists have developed a water treatment system that they say is a powerful but simple way to save lives. Four grams of chemicals can treat ten liters of dirty water for a low cost, about ten cents.
Experts say infections from dirty water kill several thousand children in developing countries every day. The Procter and Gamble company has been developing the "PUR Purifier of Water" system since 1995. The company has been working with the United States Centers for Disease control and Prevention(C.D.C.).
C.D.C. researchers tested it in Guatemala, Pakistan and Kenya. Procter and Gamble researcher Greg Allgood says cases of diarrhea(腹泻) in those studies fell by about 50 percent. Researchers from Johns Hopkins University in Maryland tested the system at a refugee camp in Liberia. Mr. Allgood says that study found a reduction of more than 90 percent. Use of the system is being expanded worldwide.
The treatment contains bleach(漂白剂) to kill disease-causing organisms. It also contains something that dirt and other particles stick to. Mr. Allgood says the chemicals can remove lead and other dangerous metals and even agricultural poisons like D.D.T.
Mr. Allgood heads the Children's Safe Drinking Water program at Procter and Gamble. He says about forty million packets of the treatment have been given to countries for free. They have been used in emergencies and in areas with limited supplies of clean water.
Clean water is a limited resource in many parts of the world. Delegates from about 130 nations attended the Fourth World Water Forum last month in Mexico City. Scientists, policy experts and others discussed ways to provide clean water to the world’s poor. Organizers say more than twenty percent of the world population lacks clean drinking water. The final declaration did not go so far as to declare water a human right. But it did say that governments, not private companies, must take the lead in improving the public’s ability to have clean water.

I love charity(慈善) shops and so do lots of other people in Britain because you find quite a few of them on every high street. The charity shop is a British institution, selling everything from clothes to electric goods, all at very good prices. You can get things you won't find in the shops anymore. The thing I like best about them is that your money is going to a good cause and not into the pockets of profit-driven companies, and you are not damaging the planet, but finding a new home for unwanted goods.

The first charity shop was opened in 1947 by Oxfam. The famous charity's appeal to aid postwar Greece had been so successful it had been flooded with donations(捐赠物). They decided to set up a shop to sell some of these donations to raise money for that appeal. Now there are over 7,000 charity shops in the UK. My favourite charity shop in my hometown is the Red Cross shop, where I always find children's books, all 10 or 20 pence each.

Most of the people working in the charity shops are volunteers, although there is often a manager who gets paid. Over 90% of the goods in the charity shops are donated by the public. Every morning you see bags of unwanted items outside the front of shops, although they don't encourage this, rather ask people to bring things in when the shop is open.

The shops have very low running costs: all profits go to charity work. Charity shops raise more than ￡110 million a year, funding（资助）medical research, overseas aid, supporting sick and poor children, homeless and disabled people, and much more. What better place to spend your money? You get something special for a very good price and a good moral sense. You provide funds to a good cause and tread lightly on the environment.

In the age of reality television, success isn’t the only way to the public eye. Failure can also create fame, just like William Hung, 21, a native of Hong Kong.

Hung recently has made an agreement with US-based entertainment firms Koch Records and Fuse Music Network. They will publish a full-length record, titled “The True Idol” on April 6.

The idol is a civil engineering student at the University of California at Berkeley. He did a version（改写本）of Ricky Martin’s “She Bangs” on the television show “American Idol 3”, on January 27. The Fox TV singing contest searches for pop stars among ordinary people. In the case of Hung, however, his act was so bad that the judges cut him off in mid-act.

Hung’s response? “I already gave my best, so I have no regrets at all.” That’s good, because any common person would have found plenty to regret: the off-key singing; the blue Hawaiian shirt worn with pants pulled up too high; the terrible dancing; the hips jerking（摇摆）to a beat that did not belong to the song, maybe not even to this planet. It was, by all accounts, bad. But, it was this very bad act that sold well.

Marc Juris, president of Fuse, explained it this way: “Every one of us is happily guilty of singing our favorite song at the top of our lungs with complete freedom, completely off-key and completely unworried. That’s what William did and immediately won the hearts of America. ”

Whatever it is, for the moment it’s big. Three websites devoted to Hung have gone up on the Internet in the past few weeks. Versions of his performance have been remixed with hip hop and techno music and have made it to the top 10 request list at a Chicago radio station.

So, what does Hung think of this?

“There were all these people saying things about me. A lot were saying I was very courageous and that I was great on the show, but some didn’t have much respect for me and some were kind of mean ”

Now, he says he’s not so sure whether to distance himself from the glamour（魅力）or to accept it. Returning to normal hasn’t been easy.

       A．Sometimes an idol behaves quite foolishly.

       B．Hung’s performance attracted the public eye.
