Memory, they say, is a matter of practice and exercise. If you have the wish and really made a conscious（自觉的）effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory “trick” work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber（理发师）shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing（有趣的）in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never got tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when “trick” of our memory can cause us great trouble.

    Not all bodies of water are so evidently alive as the Atlantic Ocean, an S-shaped body of water covering 33 million square miles. The Atlantic has, in a sense, replaced the Mediterranean as the inland sea of Western civilization. Unlike real inland seas, which seem strangely still, the Atlantic is rich in oceanic liveliness. It is perhaps not surprising that its vitality has been much written about by ancient poets.

     “Storm at Sea”, a short poem written around 700, is generally regarded as one of mankind's earliest artistic representations of the Atlantic.

    When the wind is from the west

    All the waves that cannot rest

    To the east must thunder on

    Where the bright tree of the sun

    Is rooted in the ocean's breast.

    As the poem suggests, the Atlantic is never dead and dull. It is an ocean that moves, impressively and endlessly. It makes all kinds of noise—it is forever thundering, boiling, crashing, and whistling.

    It is easy to imagine the Atlantic trying to draw breath—perhaps not so noticeably out in mid-ocean, but where it meets land, its waters bathing up and down a sandy beach. It mimics(模仿) nearly perfectly the steady breathing of a living creature. It is filled with symbiotic existences, too: unimaginable quantities of creatures, little and large alike, mix within its depths in a kind of oceanic harmony, giving to the waters a feeling of heartbeat, a kind of sub-ocean vitality. And it has a psychology. It has personalities: sometimes peaceful and pleasant, on rare occasions rough and wild; always it is strong and striking.

    This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.

    The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.

    Sensors（传感器）record each movement and send it by an ankle transmitter（脚踝发射器）to a smart phone.  Then a "virtual coach" application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.

    The socks should be useful to athletes and weekend joggers. "People think running is so easy and of course everybody can do it but not necessarily safely and well, "Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such as golf, or even to help to teach women to walk better in high heels.

    Mr. Vigano said, "People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely. "

    Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around￡120, which will go on sale in March.

    Londoners are great readers. They buy vast numbers of newspapers and magazines and of books-especially paperbacks, which are still comparatively cheap in spite of ever­increasing rises in the costs of printing. They still continue to buy "proper" books, too, printed on good paper and bound (装订) between hard covers.

    There are many streets in London containing shops which specialize in book­selling. Perhaps the best known of these is Charring Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being "the biggest bookshop in the world" to the tiny, dusty little places which seem to have been left over from Dickens' time. Some of these shops stock, or will obtain, any kind of books, but many of them specialize in second­hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written. One shop in this area specializes only in books about ballet!

    Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest. For the really cheap second­hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London. Here there is nothing so impressive as bookshops. The booksellers come along each morning and pour out their sacks of books onto small handcarts. And the collectors, some professionals and some amateurs, have been waiting for them. In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.

    You've heard of the fat suit and the pregnancy suit; now meet AGNES—the old person suit.

    AGNES stands for "Age Gain Now Empathy(换位体验)System" and was designed by researchers at MIT's AgeLab to let you know what it feels like—physically—to be 75 years old. "The business of old age demands new tools," said Joseph Coughlin, director of the AgeLab. "While focus groups and observations and surveys can help you understand what the older consumer needs and wants, young marketers never get that ‘Ah ha!' moment of having difficulty opening a jar, or getting in and out of a car. That's what AGNES provides. "

    Coughlin and his team carefully adjusted the suit to make the wearer just as uncomfortable as an old person who has spent a lifetime eating poorly and not doing much exercise. Special shoes provide a feeling of imbalance, while braces on the knees and elbows limit joint mobility. Gloves give the feeling of decreased strength and mobility in the hands and wrists, and earplugs make it difficult to hear high-pitched sounds and soft tones. A helmet with straps(带)attached to it presses the spine(脊柱).

    VAGNES has been used most recently by a group of students working on a design of an updated walker. By wearing the suit they could see for themselves what design and materials would make the most sense for a physically limited older person. Coughlin said the suit has also been used by clothing companies, car companies and retail goods companies to help them understand the limitations of an older consumer. An unexpected benefit they've found with AGNES is that it has become a powerful tool to get younger people to invest in their long-term health.

Dawn Loggins of Lawndale, N. C. is on her way to Harvard, one of the eight world­famous universities in the eastern US. Nobody encouraged her to study or paid for her special classes. This girl created her own future.

The teen was abandoned by her family last summer, when her parents and two sisters moved to Tennessee. She found herself homeless and had to spend the night on friend's sofas.

The school bus driver learned about Dawn's situation and invited Dawn to move in with her family. Soon, Dawn had a job at Burns High School. She worked from 6 a. m. to 7：40 a. m. before the first school bell rang. She swept floors and picked up trash again in the afternoons, before diving into her studies in the evenings.

Dawn's hard work paid off. She finished school with a 3. 9 GPA and scored 2, 110 on the SAT.

"There were times when I felt like it would be easiest if I gave up," the 18­year­old said." But it was never in me to give up, because I realized that I was never going to be successful unless I got an education."

Even before Dawn's family left her, she led a difficult life. Her family was poor and cups of noodles were often the only food. Dawn" studied by candlelight" because her parents couldn't afford to pay the electricity bill(电费).

Dawn has now reconnected with her family. They are proud of her accomplishments(成就)and are attending her high school graduation.
