Staring at a computer semen,Patty Hall noticed all e-mail from Christopher Mutuku,a driver she knew when volunteering in Kenya.People in his village of Kathmlgu were  36  ,he wrote.”The river has dried up and there is no water.Do you know anyone who can raise  37  to build a dam(坝)?”

Imagining a huge expensive concrete dam,Hall   38   .At 57 ,she was about to retire.after  35 years of  39  .Much as she wanted to help Kenya, she didn’t want to get  40  in a time-consuming project like this.She knew, 41  ,that the lack of clean water was a life-and-death problem in rural villages.Animals contaminated(污染)the rivers,the main  42  of drinking water.In summer,the rivers dried up completely.

“How much would it  43  .”she wrote to Mutuku.”About $7,000,”he answered.

That might be doable(可做的),she  44  .

Hall showed her students slides of Kenyan mud huts(棚屋)and asked them to  45  living without running water.She shared photos of young girls carrying h11ge containers of  46  on their backs. The girls were  47  to attend school because they spent most of their day walking  48  four miles to and from rivers,springs,orthe well in a nearby village.

49  to help,the ClaSS decided on a name—H2O for Life—and set to work.Students  50  H2O for Life wristbands(手带),holiday crafts and African-themed note cards.A student pianist held a  51  that brought in $400.A group of girls sold valentines(情人节卡)and collected $300.

In just six months,the kids  52  over $12,000.

Later, Hall flew to Kenya and visited Kathungu.The villagers held a  53  to welcome her and then showed her the dam that traps and filters(过滤)water so that it's  54  and drinkable all the year round.

Since that first e-mail,H2O for Life has  55  to 14 schools and raised $130,000 to bring clean water to communities in Africa and Central America.

Apparently,we are safe neither at home nor in the business office.We use water in both places,but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap,spraying from garden pipes,or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

       Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

       These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

       We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”
