growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is

increasing three times faster than traditional garbage as a whole.

        Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the 

weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the 

concentration (含量) of gold and other precious metals was higher in            So-called e-waste than in naturally 

occurring minerals.

         Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful 

metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which 

allow many poisonous substances to escape into the environment.

         Creating products out of raw materials creates much more waste material, up to 100 times more, than the 

material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced 

those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the

producing process are harmful as well.

        The U.S. Environmental Protection Agency notes that most waste is dangerous in that “the production, 

distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas 

release.” Individuals can reduce their contribution by creating less waste at the start — for instance, buying 

reusable products and recycling.

        In many countries the concept of extended producer responsibility is being considered or has been put in place 

as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their 

products, would they reduce the packaging in the first place?

Governments' incentive to require producers to take responsibility for the packaging they produce is usually

based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气

泡垫) that encased your television?

From the governments' point of view, a primary goal of laws requiring extended producer responsibility is to

transfer both the costs and the physical responsibility of waste management from the government and tax-payers 

back to the producers.

    When it was announced that Patrick Modiano had won the Nobel Prize in Literature on Oct.9, the Swedish Academy had not yet managed to reach the writer himself to tell him the news. as the Telegraph put it, “It was a curious case of missing personhood in an author whose career had been spent in searching others, within the confines (界限) of a single city.”

    Though the 69-year-old French author has had a successful writing career, only six of his books have been translated into English. One reason for this might be that “Modiano's storylines are as slim as the books themselves”, said the BBC.

    While most of Modiano's works don't run for hundreds of pages, they explore serious subjects. The author's signature themes are Germany's occupation during World War II and the evolution of Paris over the past century.

    Modiano's life has been greatly affected by Nazi Germany's occupation during the war, and his family's connections to it. According to New York-based newspaper Forward, his father survived the war dishonorably. When Paris's Jews were rounded up for deportation(驱逐)to concentration camps, the businessman did not join them but spent the time making money from deals with Nazis on the black market.

    “The novelist has a duty to record the traces of the people who were made to disappear,” French writer Clemence Boulouque, also an expert in Jewish Studies, told The New York magazine.

    In his more than three dozen novels, Modiano has returned again and to the same themes: Jewishness, the Nazi occupation, and loss of identity.

    Paris is another recurring(重复的)theme in Modiano's works .Most of his novels are set in the city , from the rich parts of downtown Paris to more remote suburbs where the characters try to live anonymous protect lives.

    Anne Ghisoli, the director of  Librairie Gallimard, a bookstore in Paris, concluded, “Modiano is a master of writing on memory and occupation, which haunt(萦绕)and inform his works. He is a chronicler(年代记录者)of  Paris ,its streets, and its present.”

    For their nick-of-time acts, Toby, a 2-year-old dog, and Winnie, a cute cat, were named Dog and Cat of the Year by the American Society for the Prevention of Cruelty to Animals.

    As Amy Paul choked（哽住）on a piece of apple at her home, her dog jumped up, landing hard on her chest and forcing the piece in her throat out. When the Keesling family of Indiana was about to be killed by carbon monoxide, their cat, Winnie, clawed at the wife Cathy's hair until she woke up and called for help.

    No one could explain their timely heroics.

    Both pets were rescued by their owners in infancy—Toby as a 4-week-old thrown into a garbage bin to die, and Winnie as a week-old orphan hiding under a barn, so helpless that Cathy's husband, Eric, had to feed her milk with an eyedropper.

    As the Keeslings recalled it, a gas-driven pump being used broke down, spreading carbon monoxide through the house. By the time Winnie went to rescue, the couple's 14-year-old son was already unconscious. “Winnie jumped on the bed and was clawing at me, with a kind of angry sound,” Cathy Keesling said. The state police responding to her 911 call said the family was only minutes from death, judging by the amount of poisonous gas in the house.

    Both Toby and Winnie accompanied their owners to the awards luncheon.

    One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem — inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

    Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

    In the U. S. state of Washington, a road called Interstate(州际公路；州际的)90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, busy high- way greatly limits their movements. Animals need to move to find food, to find mates, to find new places to live as their populations expand or just when conditions change, like a fire breaks out. Crossing I-90 – as the road is called – is a risky but sometimes necessary act. But soon, animals will have a safer choice. They will be able to go above it.

    To help the animals, the state is finishing work on its largest - ever wildlife bridge. The 11-meter-tall, 20 - meter - wide bridge begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing anti plants to help guide the animals across the bridge, Two-meter-thick walls will help block noise from vehicles below. Scientists chose the area because it is within a natural migration(迁徙)path for some animals.

    The I -90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges，and some are underpasses. They all aim to keep drivers and animals away from each other.

    A U. S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy (经济)about ＄8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits. Bridges, underpasses and fencing reduce I he area's animal - driver collisions by 80 percent.

    Most of the wildlife bridges are in western states. Many other areas also need such paths. But finding money for more crossings is "the- number - one problem". Patty Garvey — Darda of the U. S. Forest Service has worked on the I - 90 crossing from the start of the project. She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. "If you shut clown Interstate 90, you shut down interstate trade." she adds.
