One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem — inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

    Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

    Thomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius,” Edison said. He said that what people called genius was mostly hard work.

    But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.

    Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.

    Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work,” he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫 苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands. But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader, the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates a serious inflammation(炎症) throughout the body. But the worst is still to come.

    Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

The Greatest show on Earth

    The Olympic Games are the greatest festival of sports in the world. Every four years, many countries send their best sportsmen to compete for the highest honour in sport. As many as 6, 000 people take part in over 20 sports. For the winners, there are gold medals and glory. But there is honour, too, for all who compete, win or lose. That is in the spirit of the Olympics—to take part is what matters.

    The Olympic Games always start in a bright colour and action. The teams of all the nations parade in the opening ceremony and march round the track. The custom is for the Greek team to march in first, for it was in Greece that the Olympics began. The team of the country where the Games are being held—the host country—marches in last.

    The runner with the Olympic torch (火炬) then enters the stadium and lights the flame. A sportsman from the host country takes the Olympic oath (宣誓) on behalf of all the competitors. The judges and officials also take an oath. After the sportsmen march out of the stadium, the host country puts on a wonderful display.

    The competitions begin the next day. There are usually more than twenty sports in the Games. The rule is that there must be at least fifteen. The main events are in track and field, but there are a few days before these sports start. Each day the competitors take part in different sports, like riding, shooting, swimming, and cross-country running. Points are gained for each event. Medals are awarded for the individual winners and for national teams.

    More and more women are taking part in the Games. They first competed in 1900, in tennis and golf. Women's swimming events were introduced in 1912. But it was not until 1928 that there were any track and field events for women. Now they compete in all but half a dozen of the sports. In horse riding, shooting, and boat racing, they may compete in the same events as men.

The Kendama World Cup

Old-fashioned fun is making a comeback!

Many kids are putting down their electronic devices and picking up an ancient toy. It is called a kendama, and it possibly dates back to the 16th century.

The kendama is a small wooden hammer with three cup-shaped ends and a spike on top. A wooden ball with a center hole is attached by string to the hammer. The goal is to make the ball land in a cup or on the spike. It sounds simple, but there are over 1,000 kendama techniques and tricks to master.

The game's popularity began to grow after the Japan Kendama Association was started in 1975. Today all ages participate in various competitions, including the Kendama World Cup(KWC).

The two-year-old event, which opens in Hatsukaichi, attracts people from all over the world. Players choose 10 different tricks from an approved list. They are then awarded points corresponding to the level of each trick.

A new Kendama World Cup winner will be named tomorrow in this popular sporting event.

According to a new Agriculture Department report, U. S. forests could exacerbate global warming because they are being destroyed by natural disasters and are losing their ability to absorb planet-warming gases as they get older. The report predicts that the ability of forests to absorb carbon will start declining after 2025 and that forests could release up to 100 million metric tons of carbon a year as their emissions (排放) from decaying (腐烂的) trees go beyond their carbon absorption. Forests could become a "substantial carbon source" by 2070, the USDA report says.

The loss of carbon absorption is driven in part by natural disasters such as wildfires, tornadoes and hurricanes, which are increasing in frequency and strength as global temperatures rise. The disasters destroy forestland, destroying their ecosystem and decreasing their ability to absorb carbon, according to Lynn Riley, a senior manager of climate science at the American Forest Foundation. Aging forests also contribute. The report found that older, mature trees absorb less carbon than younger trees of the same species, and U. S. forests are rapidly aging.

This trend is likely to continue, as forests come under increasing threat from climate change and exploitation (开采). The typical tropical (热带的) forest may become a carbon source by the 2060s, according to Simon Lewis, professor in the school of geography at Leeds University. "Humans have been lucky so far, as tropical forests are cleaning up lots of our pollution, but they can't keep doing that indefinitely," he said. "We need to cut down fossil fuel emissions before the global carbon cycle starts working against us."

U. S. forests currently absorb 11 percent of U. S. carbon emissions, or 150 million metric tons of carbon a year, equal to the combined emissions from 40 coal power plants, according to the report. The loss of forests as natural carbon absorbers will require the U. S. to cut emissions more rapidly to reach net zero. "As we work to decarbonize (碳减排), forests are one of the greatest tools at our handling. If we were to lose that, it means we will contribute that much more in emissions." Riley said.
