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 turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world.

    About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria.

    The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles (微粒) of silver. The pages can be used as filters（过滤器）to remove harmful microorganisms (微生物) that can pollute drinking water. The filter kills the organisms that pass throughit.

    Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages aremade of filter paper. They are designed to be torn from the book. Water can bepoured through the paper to be cleaned.

    Ms. Dankovich, the inventor, says eachpage can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages.

    "The idea of classic texts—that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through that part," she says.

    Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful.

    Water for Life, a non-government alorganization, has provided financial support for the project.

    Hey, ladies! It's summer again and it's time for a new you! No more make-up, no more pretending! Yes, that's right! It's time to stop making ourselves beautiful for the camera, and start posting confident pictures without all the make-up and extra tricks we add onto ourselves in the hope of appearing more attractive and beautiful. Because believe it or not, we already are!

    After we wash our face and go to bed, it is not so perfect. You know it the face we should confidently be showing to the world! Who cares if you have pimples（面痕）or your eyes look small, or if you have crow's feet? Guess what? Those are actually what make you such a beautifully grown woman. And any person who doesn't think so is just not as strong as you.

    Nowadays we tend to do anything and everything to make us look as young and perfect as possible. Yet the truth is, by doing this, we are actually making our true skin get worse and badly affected by all the junk we put on. We are making ourselves believe that by changing our appearance we will be more accepted and seem more attractive to other people. And yet, our final goal is to find that without all of the make-up. What kind of twisted（扭曲的）game are we really playing with ourselves?

    So I would like to make a suggestion for all women out there to give yourself a break at least this summer. Take a couple of pictures without all of that make-up on. You don't need it every single day, especially not this hot summer! You'll be surprised that the more confident you are about showing the real side of you, the more attractive you will be to everyone else.

    Yes, the saying, “Beauty comes from within” is an old one, definitely still holds some truth today. So be brave, carefree, and make-up free! Let the world see you for who you really are!

    This is a true story that happened in Japan. In order to repair the house, a Japanese tore open the walls. Japanese houses normally have an empty space between the wooden walls. When pulling down the walls, he found that there was a lizard(蜥蜴) staying there because a nail(钉子) from outside was hammered into one of its feet. He saw this, feeling pity and curious. When he checked the nail, he found it was nailed 10 years ago when the house was first built.

    What happened? The lizard had survived in such a position for 10 years! It has been in a dark wall partition(夹层) for 10 years without moving! Then he wondered how this lizard survived for 10 years without moving a single step—since its foot was nailed! So he stopped his work and observed the lizard: What has it been doing? What and how has it been eating? Later, he didn't know from where another lizard appeared, with food in its mouth. Ah! He was astonished and touched deeply. The free lizard had been feeding it for the past 10 years.

    Such love, a beautiful love! Such love happened with this tiny creature… What can love do? It can do wonders! Just think about it: one lizard had been feeding the other for 10 long years, without giving up hope on its partner. If a small creature like a lizard can love like this, just imagine how we can love if we try.

    In many businesses, computers have largely replaced paperwork, because they are fast, and do not make mistakes. And they are honest. Many banks say that their business is “untouched by human hands” and therefore safe. But they have no thought that the growing number of computer crimes (犯罪) show they can be used to steal.

    Computer criminals (罪犯) don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller(出纳主管) at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account (账户) to another. Each time a customer whose money he had stolen questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else's account. This man was caught at last.

    Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she stole all the company's computerized records.

    Most computer criminals have been common workers. Now police wonder if this is “the tip of iceberg”. As one official says, “I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing—the ones who really know a computer works.”

    Today the Nobel Prize in Literature awarded journalist Svetlana Alexievich approximately $970,000 in recognition of a lifetime of excellence. The 67-year-old author of Voices From Chernobyl and War's Unwomanly Face was praised by the Swedish Academy "for her polyphonic(复调式的) writings, a monument to suffering and courage in our time."

    Prizes like the Nobel inspire much expectations before the announcement. People give their best guesses as to who will win, look back on past winners, and even place bets as if spectators at a Derby(赛马会).

    Literary prizes reward artistic brilliance. They help writers earn a decent living. But is the public's fascination with prize-winning authors healthy? Our impulse seems to increasingly contribute to a culture of turning authors into celebrities, where readers follow the author instead of the book.

    A story should stand on its own, as a considered, complete book, without biographical information from author. It's an idea perhaps best conveyed in Roland Barthes's 1968 essay The Death of the Author. "The image of literature to be found in contemporary culture is arbitrarily centered on the author, his person, his history, his tastes, his passions."

    Nearly 50 years later, a few still agree. "I believe that books, once they are written, have no need of their authors," New York Times bestselling author Elena Ferrante once wrote. "If books have something to say, they will sooner or later find readers; if not, they won't, "she continued. "True miracles are the ones whose makers will never be known."

    ①But the rules for submission for the Man Booker International Prize, for example, strongly encourage authors to "make themselves available for publicity". And the foundation behind the National Book Award requires finalists to participate in their "website-related publicity".

    ② In 2007, a reporter who showed up uninvited at Doris Lessing's house was the first to inform her that she had been awarded the Nobel Prize in Literature. Today the Twitterati came knocking on Alexievich's digital door hour before the award was even official. To be considered for a prize is to be a public figure.

    ③ Harry Potter series author J. K. Rowling, with over 5.6 million Twitter followers, has actively addressed readers through public appearances and social media, revealing much more than we could have imagined when we closed the final Harry Potter book. We now know the house Harry's children will be sorted into, that Dumbledore is gay," Voldemort" is actually pronounced with a silent "t", and a whole host of the other minor and major details about the backstory of the characters.

    The magical world Rowling created in her books—a relatively tight mystery with well-laid clues that led to a satisfying conclusion, which had to prove their merits to the reader based on an internal logic—is being unraveled by her own hand.

    ④ Of course, public attention also has very important benefits for authors. For three months after receiving the 2011 Pulitzer Prize in fiction, Jennifer Egan's A Visit from the Goon Squad sold about triple its print sales from before the prize, Publishers Weekly reports. On Oct. 5, 2010, in the first FT/Oppenheimer Funds Emerging Voices Awards, as Nigerian-born Chigozie Obioma accepted the prize for fiction with an easy smile, his excitement was appreciable. Given the cash prize of $40,000 for each winner, it's hard to downplay the importance of such an honor. Such awards bring necessary visibility and funding to writers facing a literary landscape dominated by white men.

    But our culture of celebrity is often too wrapped up in the way we read: How might the meaning of a work change if the author really didn't grow up in a poor neighborhood, or if he or she was abused in childhood? Readers studied the author's life as if it were the key to interpreting his or her novels.

    Behind our fascination is the question that drives all such questions: What did the author intend? By all means, let us praise brilliant work and in doing so trust that the author has already told us enough, and that the story he or she meant to tell ended with the final page.
