It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong.

    Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas — all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me.

    Then November 1,1991 began her month-long stay in the hospital—she suffered from a rare infection (感染)called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess(脓肿), and Grandma even made it into a local medical journal. Her doctor called her “the brain lady”.

    Grandma celebrated her 85^th birthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother!

If you're secretly worried about your smart phone addiction, then the new NoPhone might be just the thing you need. It looks and feels exactly like a smart phone, but it does nothing. It's just a piece of plastic that you can carry around in your hand to fool yourself.

Dutch designer Ingmar Larsen came up with the idea as a joke along with his two friends. To their great surprise, the idea received a lot of attention online and people from all over the world started placing requests for NoPhones of their own. So that's when the three friends decided to turn to collecting enough fund for mass production.

    NoPhone is currently a prototype (模型) that will cost only $12 once it hits the market It is 5.5 inches high, 2.6 inches wide and 0.29 inches thick, bringing it quite close to the latest smart phones on the market. It is described as “battery free”, “no upgrades necessary,” “shatter-proof (抗震)”, “waterproof” and “an alternative to constant hand-to-phone contact that allows you to stay connected with the real world.”

“Phone addiction is everywhere,” the designers insist. “It's ruining your dates. It's distracting you at concerts. It's blocking sidewalks. Now, there is a real solution. With a thin, light and completely wireless design, the NoPhone acts as a substitute to any smart mobile device, enabling you to always have a phone to hold without giving up potential engagement with your direct environment.”

If you're interested in NoPhone, but concerned about not being able to take selfies (自拍) anymore. Don't feel upset. The makers do have an upgrade at no extra charge—the mirror sticker. That way, they say, you can enjoy “real-time” selfies with your friends when they're standing right behind you.

    A serious problem for today's society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.

    First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs.

    Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.

    In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.

    One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.

    To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.

    The New Caledonia Barrier Reef (新喀里多尼亚堡礁)is located in New Caledonia in the South Pacific, and is the second-longest coral reef in the world, after Australia's Great Barrier Reef. The New Caledonia Barrier reef surrounds Grand Terre, New Caledonia's largest island, as well as the Ile des Pins and several smaller islands, reaching a length of 1, 500 km. The reef encloses(围住) in a lake of 24, 000 square kilometers, which has an average depth of 25 meters. The reefs lie up to 30 kilometers from the shore, but extend almost 200 km to the Entrecasteaux reefs in the northwest. This northwestern extension encloses the Belep Islands. Several natural passages open out to the ocean. The Boulari passage(通道), which leads to Noumea, the capital and chief port of New Caledonia, is noted for the Amedee lighthouse.

    The reef has great species diversity with a high level of endemism(动植物的特有分布), and is home to endangered dugongs, a kind of sea animal, and is an important nesting site for Green Sea Turtle.

    Most of the reefs are generally thought to be in good health. Some of the eastern reefs have been damaged by wastewater from nickel mining(镍开采)on Grand Terre. The waste from mining, agriculture, and grazing(放牧) has affected reefs near river mouths, which has been worsened by the destruction of mangrove forests, which help to keep wastes. Some reefs have been buried under several meters of wastes.

    In January 2002, the French government proposed(提议) listing New Caledonia's reefs as a UNESCO World Heritage Site. UNESCO listed New Caledonia Barrier Reef on the World Heritage List on 7 July 2008.

    More than two thirds of the world's polar bears will be wiped out by 2050, according to a shocking new study. By then, scientists say, global warming will have melted 42 percent of the Arctic sea ice. By 2100, only a very few of these important creatures will be left.

    The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne, who has been asked to put polar bears on the US endangered species list.

    Polar bears depend on floating sea ice as a platform for hunting seals, which are their main food. Without enough ice, polar bears would be forced to go onto the land, where they are poorly skilled hunters, and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.

    The team of American and Canadian scientists spent six months studying bears, on the ground, from spotter planes and in the lab, using computer models. Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all­time low.

    However, not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear­hunting trips.
