In her new book, “The Smartest Kids in the World,” Amanda Ripley, an investigative journalist, tells the story of Tom, a high-school student from Gettysburg, Pennsylvania, who decides to spend his senior year in Warsaw, Poland. Poland is a surprising educational success story: in the past decade, the country raised students' test scores from significantly below average to well above it. Polish kids have now outscored(超过……分数) American kids in math and science, even though Poland spends, on average, less than half as much per student as the United States does. One of the most striking differences between the high school Tom attended in Gettysburg and the one he ends up at in Warsaw is that the latter has no football team, or, for that matter, teams of any kind.

    That American high schools waste more time and money on sports than on math is an old complaint. This is not a matter of how any given student who plays sports does in school, but of the culture and its priorities. This December, when the latest Program for International Student Assessment (PISA) results are announced, it's safe to predict that American high-school students will once again display their limited skills in math and reading, outscored not just by students in Poland but also by students in places like South Korea, Belgium, the Netherlands, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.

    Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader—a mother with three children in the school—was asked about the school's flaws(瑕疵). When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”

    One of the ironies(讽刺) of the situation is that sports reveal what is possible. American kids' performance on the field shows just how well they can do when expectations are high. It's too bad that their test scores show the same thing.

    First it was worry about second-hand smoke, now there's major concern over third-hand smoke which gets into hair, clothes, furniture or a car rather than directly from a cigarette or someone breathing it out.

    To be honest, I've always been worried about the health dangers of this even though I didn't know it had a name. My worry made me reluctant to let smokers hold my babies even though they didn't smoke in my house.

    Tests for its effects have been only carried out on mice, but I don't think they can be ignored. Researchers at California University last month suggested third-hand smoke (THS) could cause type 2 diabetes, liver and lung damage.

    They analyzed how people are affected by taking in smoke from another person's clothing, hair, home, or car. They say they can see an impact on the brain and liver. Lead author Manuela Martins-Green said: “Our goal was to decide the smallest amount of time required to cause physiological changes in mice when they are exposed(暴露) to THS.” This was done using an exposure system that is the same as human exposure.

    “We found THS exposure as early as one month caused liver damage. Exposure for two months lead to further molecular(分子的) damage, and at four to six months caused even more such damage. We also found the mice showed insulin resistance（抗胰岛素） after long-term exposure.”

    “THS is a hidden danger, a silent killer. Pollutants can be absorbed through the skin and through breathing.”

    “Although our research was not done on humans, people should be aware that hotel rooms, cars and homes that were used by smokers are very likely to be polluted with THS.” Martins-Green believes most people don't know they're being exposed to THS, or don't believe in the damage it can do.

    THS toxins(毒素) remain on surfaces for many years, and resist even strong cleaning agents.

    Sweat (汗水)rail its way down my cheek. It was hot, but the air was still and wet. One final play and the State Softball Championship was ours.

    I looked towards people who were watching the game. Sure enough, I found my mom. I always wished my dad were here. The farm needed his full attention, but I did not care.

    Finally, we won! State Champs! I let out a scream of happiness, fall of tears. My mom made a “V” to celebrate my success and smiled. I smiled back at her.

    We all received medals (奖牌), but I cannot remember any of it. I concentrated my thoughts on my dad, I ran to my mom, asking for her cell phone. I had to tell my dad about the happiest day of my life, and complained (抱怨）about how he did not care.

    The phone rang twice, and no one answered. My heart sank with sadness, but I tried again anyway.

    “Hello?” My dad answered.

    “Dad!” I cried. “We won State!” Silence.

    “Dad?” I could hear something on the other end. “Are you crying?”

    “I'm just really happy for you, Meggie,” he said. “And I'm sorry I couldn't be there.”

    An apology（抱歉）was all I needed. I hung up the phone feeling relaxed, and I began to understand how it must feel to be a father. I forgave him for never being there. He worked so I could play. My father loved me enough to let me experience life^ happiest moments without him.

    A man going abroad to work leaves his young lady crying. "Don't worry, I will write to you every day," he said. For years he did write to her. But since he was happy with his job, he had no immediate plans of going home. One day, he received a wedding invitation. His girlfriend was scheduled to be married. To whom? To the mailman bringing regularly the letters of her boyfriend! Indeed, distance does make hearts struggle.

    While presents are important, love demands what is basic: presence of the beloved.

    Martha was busy with her job. She believed she had to work harder because she loved her father who had serious disease. She had to provide for his expensive medicine. Her brothers and sisters meanwhile stayed with their father most of the time. They bathed him, sang for him, spoon­fed him or simply kept him company.

    One day Martha was hurt. She overheard her father telling her mother, "All our children love me except Martha." "How can this be?" Martha thought. "Am I not the one killing myself in my work to earn money to buy for his medicine? My brothers and sisters do not even provide their share in the expenses as much as I do."

    One night, as Martha was as usual late in going home, she peeped for the first time in the room where her father was lying. She noticed that her father was still awake. She decided to come close at his bedside. Her father held her hands and said, "I miss you. I don't have much time. Stay with me." And she stayed with her father holding his hand the whole night.

    The next morning Martha said to everyone, "I have taken a leave of absence. I would like to be with my father. I will bathe him and sing for him from now on." Her father had a beautiful smile. He knew this time Martha loved him.

    As children, we need the assuring presence of our loved ones. Adult people need no less.

    The cold and icy land that is the Eskimo's home is a dangerous one. The Eskimo once believed that to be safe from danger he had to obey taboos(禁忌). Taboos were rules that told him what he must do and must not do.

    The Eskimo had taboos connected with almost everything he did. He had to keep them in mind at all times. He believed that to break one would bring disaster. For the Eskimo, it was taboo to store reindeer(驯鹿) and seal (海豹) meat together. He could not even eat them on the same day. He believed the Goddess Sedna had separated the land animals from the sea animals. He thought bringing them together would cause the hunting to be bad.

    There were other taboos concerning animals. When a dead seal was brought into the house, the women had to stop working. They had to give its spirit a drink of water. If they did not, the spirit would be angered. It would keep other animals from being caught.

    When the Eskimo broken a taboo, he believed a black cloud formed around his head. He had to tell the others in the village what he had done. He thought that if he did not tell his neighbors, they would catch the black cloud. Then the whole village would have bad luck.
