Book Pages Could Provide Safe Drinking Water
The expression "a thirst for knowledge" may soon have a new meaning for millions of people who have no way to get clean water. Researchers have developed a book with specially treated pages that can make water safe to drink. The researchers say their invention could improve the lives of many in the developing world.
An estimated 600 to 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is infected with harmful bacteria or other contaminants.
But researcher Teri Dankovich has developed a special book that could turn dirty water into clean, drinkable water.
The Drinkable Book was developed to filter polluted water.
The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles of silver. The pages can be used as filters to remove harmful microorganisms that can pollute drinking water. The filter kills the organisms that pass through it.
Ms. Dankovich says each page can treat up to 100 liters of water.
Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be decontaminated.
Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful.
Ms. Dankovich recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she has considered adding classic literature on the book's pages.
"The idea of classical texts - that's of interest maybe later. But we have discussed a little bit more exciting text. But we really haven't had the time to go through that part," she says.
Water for Life, a non-governmental organization, has provided financial support for the project.

1.millions of 上百万的；数百万；数以百万计的
Millions of people were immolated in World War I.
2.developing world 发展中国家
For many people living in poverty in the developing world, however, these options are not available.
3.pass through 穿过…；通过…
If you drink too much all at once or too fast, it will simply pass through you, with little or no benefit to your body.
4.financial support 财政支持；经济支援
Adding to the pressure to obey, many young adults rely on their parents for financial support.

proved to be 结果是，证明为
Ladies and gentlemen, I believe that Beijing will prove to be a land of wonders to athletes, spectators and the worldwide television audience alike.
Few could have foreseen how far-reaching that decision would prove to be.

I have nothing more to add on this case, since it is a legal issue. I think you will understand.
When you’re already fairly productive, you can’t simply add on more work.
对于数百万喝不到干净饮用水的人来说，“求知（纸）若渴”这一表达将被赋予一种新的意义 。研究人员已经研发出一种经过特殊处理过，可过滤出安全饮用水的书页 。研究人员称他们的发明可以改善许多发展中国家的生活水平 。
全世界大约有6到7亿人因饮用不干净的水患病甚至死亡 。这些水都受到了有害细菌或其他污染源的污染 。
如今，研究员Teri Dankovich发明出了一种特殊的书，可以将脏水转化为干净的可饮用的水 。
这本书总共25页 。每一页的厚度大约一毫米 。书页中含有非常小的银粒子 。因此书页可以作为过滤器来消除有害微生物，达到净化污水的目的 。过滤的过程中可将细菌清除干净 。
书页上的一张张图片是为了帮助那些不识字的人理解关于污水的危害以及如何使用该书 。书页是由过滤纸制成 。使用时把书一页页地撕掉，这样通过纸的污水便得到净化 。
Teri Dankovich和另一名研究人员在孟加拉国，加纳以及南非进行了试用 。实验的结果很成功 。
Dankovich女士最近在波士顿马萨诸塞州举行的美国化学学会的会议上展示了她的这一发明 。甚至有记者问到是否考虑在书的页面上增加一些经典的文学作品 。
Dankovich女士表示“增加经典文学作品的建议，以后可能会考虑 。目前我们已经讨论出一些比较令人兴奋的刊登内容 。只是我们还没有时间去处理这一部分 。”
