He's an old cobbler（修鞋匠）with a shop in the Marais,a historic area in Paris.When I took him my shoes,he at first told me: “I haven't time.Take them to the other fellow on the main street ; he'll fix them for you right away.”

    But I'd had my eye on his shop for a long time.Just looking at his bench loaded with tools and pieces of leather,I knew he was a skilled craftsman（手艺人）.“No,” I replied,“the other fellow can't do it well.”

     “The other fellow” was one of those shopkeepers who fix shoes and make keys “while-U-wait”-without knowing much about mending shoes or making keys.They work carelessly,and when they have finished sewing back a sandal strap（鞋带）you might as well just throw away the pair.

    The man saw I wouldn't give in,and he smiled.He wiped his hands on his blue apron（围裙）,looked at my shoes, had me write my name on one shoe with a piece of chalk and said,“Come back in a week.”

    I was about to leave when he took a pair of soft leather boots off a shelf.

     “See what I can do?” he said with pride.“Only three of us in Paris can do this kind of work…”

    When I got back out into the street,the world seemed brand-new to me.He was something out of an ancient legend,this old craftsman with his way of speaking familiarly,his very strange,dusty felt hat,his funny accent from who-knows-where and,above all,his pride in his craft.

    There are times when nothing is important but the bottom line,when you can do things any old way as long as it “pays”,when,in short,people look on work as a path to ever-increasing consumption（消费）rather than a way to realize their own abilities.In such a period it is a rare comfort to find a cobbler who gets his greatest satisfaction from pride in a job well done.

Yawning（哈欠）sends out certain messages—either “Oh, this movie is boring" or "I probably need to get some sleep". But did you know that a yawn can also help your brain to cool down when it is so overheated?

    A new study, led by a research team of Princeton University, has indicated（表明）that yawning could be the brain's natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily.com.

    The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.

    When people yawn, their jaw is also stretched, which increases blood flow and may also help cool the brain.

    The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawn. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.

    However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.

    According to Gallup, this is the first report to show that yawning frequencies(频率) change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.

    Yesterday I went to the nursing home to visit my grandma. She just got out of the hospital recently where she had some serious operations. I wanted to surprise her after work so I stopped by for a quick visit.

    When I got there, she was so happy to see me. We hugged, kissed and exchanged greetings. Then I heard a woman crying. It was my grandma's roommate. The curtain was drawn so I could not see her. She started calling out a name that wasn't mine but she was certainly talking to me, begging me to go to her side of the room.

I ignored her at first and continued talking with my grandma. Then she started begging and saying, "Please, come to see me!" So I went to see her.

    When I drew the curtain back, she looked so old but flashed me the biggest smile! She opened her arms wide for me to hug her so I bent low and gave her a hug. I sat on her bed and talked with her for a few minutes. She kept calling me by the other name, but I did not correct her. She told me stories as if I had been there when they happened.

Finally I went back to talk with my grandma. Then the woman started crying again, saying, "Please, come back." She finally slept.

    I stopped by the nurse's station and the nurse told me that the lady suffers from Alzheimer's (老年痴呆症). I mentioned the name she had called me. The nurse told me it was the lady's daughter's name. Then I understood why she wanted me to go to visit her.

    We will all get old some day. Some of us will have broken minds like the lady and some of us will have broken bodies like my grandma. As I was leaving, I promised I would go back and visit the lady, even after my grandma moved back to her home.

    A family is a collection of people who share the same genes but cannot agree on a place to pull over for lunch. Ed and I, plus his parents and sister Doris and eight-year-old niece Alisha, are on a road trip to Yosemite. Ed wants Subway, I want. In-N-Out Burger, Doris wants Sonic. In the end, we compromise on McDonald's, where Alisha will get an action figure.

    It's a three-hour drive to Yosemite, but we're taking a little longer, as we're working in a tour of Highway 80's public restrooms. As the saying goes, "Not one bladder（膀胱）empties but another fills." Many of these restrooms belong to gas stations. I prefer them to the high-tech ones on planes.

    We get back on the road. Ed is driving now. When all the tabloids（小报）have been read, the travel has grown tedious and anyone under age 12 asks "Are we there yet?" at ever-shortening internals. Just outside Manteca, California, we stop for coffee. At a Starbucks checkout, Ed buys a CD of Joni Mitchell's favorite musical picks. The hope is that it will have a calming effect.

    As we pull back onto the highway, it starts to pour. Then something amazing happens. As we climb the mountain, the rain turns to snow. The pines are spotted with white. We're struck dumb（说不出话）by the scene outside. For a solid 15 minutes, everyone forgets about their bladder, their blood sugar and the temperature. Alisha has never seen snow, so we pull over to make snowmen and catch snowflakes on our tongues. Then Ed realizes we need tire chains, and we have to turn back and drive 30miles to Oakhurst. "Good," says Doris. "There was a very nice restroom there."

    A famous doctor once received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.

The child's mother was very much obliged to the doctor, and she called on him to thank him for what he had done for her child. "Doctor," she said, "you have saved my little son. I don't know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it." The doctor stood up and said coldly, "Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done." The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, "Perhaps you will tell me how much your fee is?"

    "Fifty pounds", he answered.

    The lady opened the little purse and took out four fifty-pound bank notes. She handed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying good bye to the doctor, went out of the room.

    In an unmanned supermarket, a customer waits to pay. With the use of advanced digital payment technology, including biological recognition and in-depth learning, the man leaves in a minute. There's no cashier in the store. At a large university, students use a hand-scanning machine that authorizes their entry into the gym. Those people are using "smart machines" which identify people by their physical characteristics. These new devices use fingers, hands, faces, eyes and voices. Some machines may even use smells. This new technology, called biometrics, gets information from parts of the body.

    In the past, biometric machines were used mainly in government agencies or in prisons. But now that the cost of the technology is lower, these machines are starting to be used everywhere, from border services to schools.

    Some people, however, are concerned that these machines will mean the destruction of personal privacy. They worry that the machines will get personal information about them, know it seems like these machines are invading our privacy, but actually, biometric machines help to protect it," says Jay Tarkett, who works at a company that develops the machines, "They can be used instead of passwords on a computer, for example. They can also identify criminals at airports. So, really, they help to promote public safety, and all the information stored is kept confidential by the machine itself."

    Some people don't like the idea of using fingerprints because they associate them with criminals, and feel like they are being accused of something, In addition, they don't work for some people, such as bricklayers, who wear down their fingerprints. Yet, face recognition does work well because the subject doesn't really have to do anything, To cash a check at a bank, for example, the customer has to do nothing more than look at a machine similar to an automatic teller. If the face matches the picture kept on file, the customer gets the money with no problems, The need to carry identification with you from place to place, then, would all but cease. It has been found that the hand scan works well ill the college gym. Before this machine was used, students at the college entered the gym using cards similar to credit cards. The problem was that students often lost or forgot their cards. With the hand-scanning machine, however, the problem was solved right away.

    But the machines are still new, and there can be problems. For example, voice recognition works on the phone, but it is not precise, and can be tricked. Another constraint(限制)we notice；, with machines that use face recognition in particular, is that they can be fooled if people color their hair or gain a lot of weight. However, this particular problem may be solved by a new type of technology that scans a person's iris, the colored part of the eye. It can even identify the person from a few feet away, recognizing a customer as he or she approaches the ATM.
