It's 10:00 on a beautiful Sunday morning in California. To my left is some of the most beautiful coastline. I'm walking along a road ordinarily packed with cars on days like this, but today, thanks in part to my $135 entry fee, it is closed to traffic.

    There's only one problem: I should be running, not walking. Over the past year, I've spent hundreds of dollars on running gear(设备) and race entry fees. I've jogged than 1,600 miles training for this event.

    Dozens of runners pass me on either side, each of them experiencing varying degrees of sadness similar to my own. Most of them, like me, have traveled hundreds of thousands of miles to get here, spending $500, $1,000 or more to participate in this event.

    Actually I'm by no means a competitive athlete. My best finish ever was fourth place, in a 5-kftometer race with only 74 participants, many of whom were walking the entire course.

    Last year, over 500,000 runners completed a marathon in the U.S. alone. Nearly all of these runners had absolutely no chance of victory. The PR-personal record-is everyone's definition of a “good race,” whether he finishes in first or 301st.

    I should buy a new watch that not only tracks my location by GPS, but also by counting steps. This can more accurate and much more expensive. Finally, I have reached the finish line. I know that the official race photographers will be taking photos as I cross the line, so I raise my arms in “victory” I finish, in a time of 3:37:55, good for 354th place.

    A few days after the race, the race organizers email me a link to a site where I can preview my official photos 一 and download them, for a fee, of course.

    I wish I could say the feeling was unique; it's probably not Indeed probably a feeling most runners get in most marathons. Running a lot of marathons 9 in fact, may not even be good for your health.

    In America, marathoning is a rich person's sport.

The Scar of Love

    Some years ago on a hot summer day in south Florida a little boy decided to go for a swim in the old swimming hole behind his house.In a hurry to dive into the cool water,he ran out of the back door,leaving behind shoes,socks and shirt as he went.He flew into the water,not realizing that as he swam toward the middle or the lake,an alligator（短嘴鳄）was getting close.The mother in the house was looking out of the window and saw the two as they got closer and closer together.In great fear,she ran toward the water,yelling to her son as loudly as she could.Hearing her voice,the little boy became alarmed and made a U—turn to swim to his mother.It was too late.Just as he reached her, the alligator reached him.From the dock,the mother grabbed her little boy by the arms just as the alligator snatched（抓住）his legs.That began an unbelievable tug-of-war（拔河比赛）between the two.The alligator was much stronger than the mother,but the mother was much too passionate to let go.A farmer happened to drive by,heard their screams;rushed from his truck,took aim and shot the alligator.

    Remarkably,after weeks and weeks in the hospital,the little boy survived.His legs were extremely scarred by the terrible attack of the animal.And on his arms,were deep scratches where his mother's fingernails dug into his flesh in her effort to hang on to the son she loved.

    The newspaper reporter,who interviewed the boy after the trauma（外伤）,asked if he would show him his scars. The boy lifted the pant legs.And then,with obvious pride,he said to the reporter,"Look at my arms.I have great scars on my arms,too.I have them because my mum wouldn't let go."

    You and I can identify with（认同）that little boy.We have scars,too.Not from an alligator,but the scars of a painful past.Some of those scars are unsightly and have caused us deep regret.But,some wounds,my friends,are because we have refused to let go.

    January means it's time for coats and gloves and cold weather. While many of us are preparing ourselves for the cold weeks ahead, in some cities winter is the “hottest” season of all because it's the time for winter festivities.

    Every year 2 million people visit the Sapporo Snow Festival in Japan. This internationally well-known event began in 1950, when some local high-school students built six snow statues in Odori Park. Since then, the festival has grown to include lots of snow sculptures as well as a snow-sculpting contest that draws competitors from all over the world.

    In December, Finland created its 13th annual Snow Village, which will remain open until April, if weather permits. Snow Village lies nearly 200 kilometers north of the Arctic Circle. The village is designed by builders skilled in working with snow and ice. Visitors can take a tour of the village, eat in a restaurant made of ice or go dancing in the disco igloo(拱形圆顶小屋). They can also spend the night in a hotel made of snow. There's even an ice chapel(小礼拜堂) for couples who want to get married in Snow Village.

    Since 1935, the Fur Rendezvous has been held every February in Anchorage, Alaska, America's most northern state. Among the festival's many attractions is the World Championship Sled Dog Race, which draws sled dog teams from many countries. Dogs also take center stage in the Dog Weight Pull, in which dogs compete to see which one can pull the heaviest weight. The festival features sports like skiing, basketball, boxing and softball as well as the Grand Prix Auto Race in downtown Anchorage. True to the festival's name, there's also a fur auction(拍卖), where buyers buy real Alaskan furs. The first Fur Rendezvous lasted only three days. Now it's a 10-day event that attracts thousands of visitors.

Dear Alcohol,

    You've been around forever. I can remember all the pain you've caused for me.

    Do you remember the night you almost took my father's life? I do. He loves you. Sometimes I think he loves you more than he loves me. He's addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn't the only one hurt by you that night.

    Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. "I'm so embarrassed," they said as I held their hair back so that they could vomit. "I'm sorry," they said when I called taxies for them, walking them out and paying the driver in advance. "This won't happen again," they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.

    Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn't realize her brother was in the midst of it all. She never saw him again. And it's all your fault.

    I wish you'd walk out of my life forever. I don't want anything to do with you. Look at all the pain you've caused. Sure, you've made people happy too from time to time. But the damage you've caused in the lives of millions is inexcusable. Stop luring (引诱) in the people I love. Stop hurting me, please.

Sincerely,

Me

    Martha had been working for Miller Laboratories for two years, but she was not happy there. Nothing significant had happened in the way of promotions or salary increases. Martha felt that her supervisor, a younger and less experienced person than she, did not like her. In fact, the supervisor often said unpleasant things to her.

    One day, while talking with her friend Maria, she mentioned how discouraged she was. Maria gave her the name of a cousin of hers who was director of Human Resources Department for a large chemical company. Martha called him the next day and set up an interview on her lunch hour.

    During the interview, Mr. Petri said, "You're just the kind of person we need here. You're being wasted in your other job. Give me a call in a day or two. I'm sure we can find a place for you in our organization." Martha was so happy that she almost danced out of the building.

    That afternoon, Ruth Kenny, her supervisor, saw that Martha had come in ten minutes late from her lunch hour and she said, "Oh, so you finally decided to come back to work today?"

    This was the last straw. She could not take another insult. Besides, Mr. Petri was right: she was being wasted in this job.

    "Look," she said angrily, "if you don't like the way I work, I don't need to stay here. I'll go where I'm appreciated! Goodbye!" She took up her things and stormed out of the office.

    That night she called Maria and told her what had happened and then asked Maria, "What do you think?"

    "Well," said Maria carefully, "are you sure about the other job?"

    "Well, not exactly, but..."

    Maria continued, "Will you be able to get a recommendation from Ms. Kenny if you need one?"

    "A recommendation?…from Ms. Kenny?" hesitated Martha, in a worried tone.

    "Martha, I hope you didn't burn your bridges," Maria said. "I think I would have handled it differently."

    Children exposed to "safe" levels of air pollution in the womb(子宫) develop brain damage that damages their concentration, a study has shown.

    The research is the first too link common pollutants such as nitrogen(氮) dioxide and soot(油烟) to changes in the brains of unborn babies that mean they may struggle to focus at school in later life. The findings suggest that even comparatively clean city air could lead to worse academic performance and an increased risk of mental health problems such as addition or attention deficit hyperactivity disorder(缺陷多动障碍).

    In recent years scientists have found that children who grow up surrounded by air pollution are more likely to have a broad range of "neuro(神经)­developmental" difficulties, including autism and various kinds of cognitive(认知) damage. However, only a handful of studies have looked at the ways in which the poisonous gases and microscopic particles(微粒) that mothers and young children take in affect the brain during critical stages of its growth.

    A group led by Monica Guxens, of the Barcelona Institute for Global Health, found that exposure to air pollution before birth appeared to have slowed the development of several brain regions that play an important role in people's capacity for self­denial and sustained effort. This lack of inhibition could in turn cause "cognitive delays" when the children get older, the scientists argue in Biological Psychiatry.

    "We need this function in our daily life," Dr. Guxens said. "It controls our impulses(冲动) and our selective attention. Children need it to learn and for making decisions in later life. We're interested to see what will happen: is there going to be an impact on their academic work, are there going to be clinical implications? It might be that this will lead to problems later."

    The results were drawn from MRI scans of 873 children between the ages of six and ten in Rotterdam. Even though 99.5 percent of their mothers had lived with nanoparticle pollution levels well below EU legal limits while they were pregnant the pollution still appeared to have taken its toll(伤亡人数).

    Children who had been exposed to more pollution in the womb did worse on a test of their ability to block out irrelevant stimuli(刺激). They also had thinner outer layers in the precuneus(楔前叶) and the rostral middle frontal regions of their brains, both of which are involved in cognitive inhibition, which refers to the mind's ability to tune out stimuli that are irrelevant to the task at hand or to the mind's current state.

    Experiments on animals show that so­called fine particles are able to pass through the placenta and affect the brain of the fetus(胎儿). Dr Guxens said there were probably no such thing as a safe concentration of air pollution.
