科目：高中英語 來源： 題型：

Christopher Charles studied Health Science at a university in Canada. After graduation,he went to Cambodia and lived in a small village. There,he studied a serious health condition called anaemia(貧血癥) . People with anaemia do not have enough iron in their bodies. Charles did blood tests on many people and discovered something shocking. About 90% of women and children had anaemia. He knew he could not leave Cambodia.

Iron medicine is the usual treatment for anaemia,but it costs a lot. Cooking with iron pots (鍋) could help because it would release iron into every meal. But iron pots are heavy and expensive. Also,food goes bad if it is left in an iron pot. So Charles added an iron bar to a cooking pot. It didn't cost much money and it did release lots of iron. However,instead of cooking with it,people usfed it to hold down papers or support a table with a broken leg.

Finally Charles created the iron fish. People in Cambodia eat fish every day and they believe fish are lucky. So people are willing to put the iron fish in their cooking pots.

I't turned out that,the iron fish not only improved people's health,but also helped the local economy (經濟) . People who use the iron fish miss fewer days at work. And some people even get jobs from the iron fish. They make and supply the iron fish.

More and more people are using the lucky iron fish in Cambodia now. But anaemia is a worldwide problem,which affects one in three people in the world. In some places people do not eat fish. Charles says this is not a problem. “The iron could be shaped in a different form. What is important is that it is right for each culture. So people will use it and it will improve their lives,” he says.
