          One early morning, I went into the living room to find my mother reading a thick book called Best Loved Poems to Read Again and Again. My interest was aroused only by the fact that the word “Poems”appeared in big, hot pink letters.

      “Is it good?” I asked her.

“Yeah,” she answered. “There's one I really like and you'll like it, too.' I leaned forward.

“‘Patty Poem,'” she read the title. Who is Patty? I wondered. The poem began:

She never puts her toys away,

                Just leaves them scattered(散乱的)where they lay,…      

The poem was just three short sections. The final one came quickly:

          When she grows and gathers poise(稳重),        

           I'll miss her harum-scarum(莽撞的) noise,        

           And look in vain(徒劳地) for scattered toys.       

And I'll be sad.      

    A terrible sorrow was hed over me. Whoever Patty was, she was a mean girl. Then,the shock.

“It'syou, honey,” My mother said sadly.

    To my mother, the poem revealed a parent's affection when her child grows up and leaves. To me, the “she” in the poem was horror. It was my mama who would be sad. It was so terrible I burst out crying.

    “What's wrong?” my mother asked.

    “Oh Mama,” I cried. “I don't want to grow up ever!”

      She smiled. “Honey, it's okay. You're not growing up anytime soon. And when you do, I'll still love you, okay?”

    “ Okay,”I was still weeping. My panic has gone. But I could not help thinking about that silly poem. After what seemed like a safe amount of time, I read the poem again and was confused. It all fit so well together, like a puzzle. The language was simple, so simple I could plainly understand its meaning, yet it was still beautiful. I was now fascinated by the idea of poetry, words that had the power to make or break a person's world.

        I have since fallen in love with other poems, but “Patty Poem” remains my poem. After all, “Patty Poem” gave me my love for poetry not because it was the poem that lifted my spirits, but because it was the one that hurt me the most.

    In France, a man walks on what can only be described as a human-sized hamster wheel. The wheel moves around and around, as the man keeps walking. What is he doing? He is lifting a heavy object to the top of a tower the same way workers moved such objects 800 years ago.

    In the 13th century, workers did not have the 100-meter tall cranes they now use to build tall buildings. So they had to be creative and come up with simple machines to get their work done.

    The man on the large wheel is walking at a reasonable speed. The wheel turns and pulls a rope connected to a pulley(滑轮)at the top of the tower. Another rope tied to the pulley lifts supplies from the ground.

    This is just one way skilled craftsmen arc building a 13th-century castle without using modern tools. Crew have been working on the castle since 1997. It is being built in the Burgundy area of central France. Organizers expect the work to last another 10 to 15 years. That means it will take close to 30 years to finish the project.

    The crew are making progress at about half the speed of the workers from 800 years ago. That is because many of them are accustomed to using modern tools. When the crew use heavy chisels(凿子）and hammers to break rock, as they did hundreds of years ago, they are learning as they go. The goal of the project is to learn more about old building techniques in case they might be of use today.

    Clement Guerard, 44,is a stonemason; he cuts and builds with stone. He has been working on the tower for 17 years. He said one way he is able to work on something like this for so long is by forgetting “some of the pace of modern life", he is able to adapt to working by hand.

    French surgeons have performed what they said on Wednesday was the world's first partial face transplant— giving a new nose, chin and lips to a woman attacked by a dog.

    Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation.

    “The patient is in an excellent state and the transplant looks normal,” the hospitals said in a brief statement after waiting three days to announce the pioneering surgery.

    The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are “extremely difficult, if not impossible” to repair using normal surgical techniques, the statement said.

    The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to resemble the woman who had been the source of her new face.

    The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants.

    Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area's high sensitivity to foreign tissue.

    Teams in France, the United States and Britain had been developing techniques to make face transplants a reality.

    There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers.

    Experts say that although such medical advances should be celebrated, the transplant had thrown up moral（道德的）and ethical(伦理的) issues. Little is known about the psychological effect of the transplant.

    It was dark. As John was walking on his way home, he suddenly found an ugly old man staring at him.

    The old man said, "Son, why don't you get a book? It will keep you company."

    John noticed all the books the old man had were related to the super nature (超自然界). Trying to act bravely, he found one and the old man said, "That's an interesting book. It's $25."

    The old man kept staring at John, which almost frightened him. He quickly searched his pockets and found $25.

    John quickly paid for it. Then the old man called out, "Whatever happens, don't turn to the last page. Do remember, or you will regret it!"

    Reaching home, John heard his parents talking about a strange old book seller that appeared only at night during a full moon and then disappeared. Nervously, he ran straight to his room.

    At midnight, as he was sound asleep in bed, a blast (股) of cold wind blew in through the window and woke him up. He looked at his table and saw the book. For a while, he was frozen in fear, but he was so curious. Slowly he got out of bed and carefully picked up the book.

As he took a look at the last page, he cried out and fainted (晕倒).

    This is what he read on the last page!

    While it's books that make a library, being in lovely surroundings may provide inspiration and help you work a little bit harder. Here are some of the coolest libraries of the world.

    Library of Birmingham – Birmingham, U.K.

    The new Library of Birmingham is said to be not only Britain's biggest public library, but also the largest in Europe. Designed by Dutch architects, this replacement for the Birmingham Central Library was opened in 2013 and has a wealth of resources within its walls, including adults and kids' libraries, music collections, a Shakespeare Memorial Room, and even a gym room. Gardens crown the roof, while the changing seasons bring variations in the shadows and reflections inside.

    National Library of France – Paris, France

    The National Library of France, which now contains an astonishing collection of 30 million, dates back to the 14th century and this royal library was set up at the Louvre by King Charles V. The Library was moved to Rue de Richelieu site in 1868, with major design work carried out by French architects Henri Labrouste and, following his death, Jean-Louis Pascal. Here, the reading rooms are elegance itself. There are more than just books to be found.

    State Library of New South Wales – Sydney, Australia

    The public State Library of New South Wales holds the honor of being the oldest institution of its kind in Australia. It was originally set up as the Australian Subscription Library in 1826, but it wasn't until 1942 that its permanent home was ready. Designed by Sydney architect Walter Liberty Vernon and completed in 1910, the magnificent sandstone Mitchell Wing is one of the architectural highlights.

Seattle Central Library – Seattle, Washington, USA

    Seattle Central Library's distinctive design ensures it stands out. Architect Rem Koolhaas is one of the names attached to its design. Architects sought to envelop the 11-story building with "a layer of transparency", using a skin of glass and metal. The finished article houses about 1.45 million books and other things, as well as more than 400 computers available for public use. The building, which opened in 2004, was included on the American Institute of Architects' list of America's 150 favorite buildings in 2007.

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have-in just two years-nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable (商业可行性) generation of solar fuels that could replace coal, oil, and other fossil fuels.

Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and carbon dioxide. Researchers are exploring a range of possible target fuels, but one possibility is to produce hydrogen by splitting water.

Each water molecule (分子) consists of one oxygen atom and two hydrogen atoms. The hydrogen atoms are extracted, and then can be reunited to create highly flammable hydrogen gas or combined with CO 2 to create hydrocarbon fuels, creating a plentiful and renewable energy source. The problem, however, is that water molecules do not simply break down when sunlight shines on them-if they did, the oceans would not cover most of the planet. They need a little help from a solar-powered catalyst (催化剂).

To create practical solar fuels, scientists have been trying to develop low-cost and efficient materials that perform the necessary chemistry using only visible light as an energy source.

A new method was developed through a partnership between the Joint Center for Artificial Photosynthesis (JCAP) and Berkeley Lab's Materials Project, using resources at the Molecular Foundry and the National Energy Research Scientific Computing Center (NERSCC). JCAP focused on developing a cost-effective method of turning sunlight, water, and carbon dioxide into fuel. It is led by Caltech with Berkeley Lab as a major partner. The Materials Project is a program based at Berkeley Lab that aims to remove the guesswork from materials design in a variety of applications.

"What is particularly significant about this study, which combines experiment and theory, is that in addition to identifying several new compounds for solar fuel applications, we can also learn something new about the basic electronic structure of the materials themselves." says Neaton, the director of the Molecular Foundry.
