I call my story the story of a bad boy, partly to distinguish myself from those faultless young gentlemen, and partly because I really was not an angel. I may truthfully say I was a friendly, impulsive(易冲动的)teenager. I didn't want to be an angel. In short, I was a real human boy, such as you may meet anywhere in New England.

Whenever a new scholar came to our school, I used to ask him "My name's Tom Bailey; what's your name?" If the name struck me favorably, I shook hands with the new pupil cordially, but if it didn't, I would turn and walk away, for I was particular on this point.

I was born in Rivermouth almost fifty years ago, but, before I became very well acquainted with that pretty New England town, my parents moved to New Orleans. I was only eighteen months old at the time of the move, and it didn't make much difference to me where I was, because several years later, when my father proposed to take me North to be educated, I had my own view on the subject. I instantly kicked over the little boy, Sam, who happened to be standing by me at the moment, and declared that I would not be taken away to live among a lot of Yankees! You see I was what is called "a Northern man with Southern principles," I had no recollection of New England: my earliest memories were connected with the South. I knew I was born in the North, but hoped nobody would find it out. I never told my schoolmates I was a Yankee, because they talked about Yankees in a scornful way which made me feel that it was quite a shame not to be born in the South.

And this impression was strengthened by Aunt Chloe, who said, "There wasn't no gentlemen in the North no way."

    With this picture of Northern civilization in my eye, the readers will easily understand my terror at the bare thought of being transported to Rivermouth to school, and possibly will forgive me for kicking over little Sam, when my father announced this to me. As for kicking little Sam, I always did that, more or less gently, when anything went wrong with me.

    My father was greatly troubled by this violent behavior. As little Sam picked himself up, my father took my hand in his and led me thoughtfully to the library. He appeared strangely puzzled on learning the nature of my objections to going North.

"Who on earth, Tom, has filled your brain with those silly stories?" asked my father calmly.

"Aunt Chloe, sir, she told me."

My father devoted that evening and several evenings to giving me a clear account of New England: its early struggles, its progress, and its present condition. I was no longer unwilling to go North; on the contrary, the proposed journey to a new world full of wonders kept me awake nights. Long before the moving day arrived I was eager to be off. My impatience was increased by the fact that my father had purchased for me a fine little Mustang pony, and shipped it to Rivermouth two weeks before the date set for our own journey. The pony completely resigned me to the situation. The pony's name was Gitana, which is the Spanish for "gypsy", so I always called her Gypsy.

    Finally the time came to leave the vine-covered mansion among the orange-trees, to say goodbye to little Sam(I am convinced he was heartily glad to get rid of me), and to part with Aunt Chloe. I imagine them standing by the open garden gate; the tears are rolling down Aunt Chloe's cheeks; they and the old home fade away. I am never to see them again!

    Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street.

    Adult(成年人) drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, and the life of American people. Most of the radio programmers（节目）are music.

    Pop or popular music singers make much money. They make a CD or tape which radio stations use in many places. Once the popular singer is heard all over the country, young people buy his or her tapes. Some of the money from these tapes goes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.

    There are other kinds of music that are important to Americans. One is called folk music. It tells stories about the common life of Americans. Another is called western or country music. This is started by cowboys（牛仔）who would sing at night to the cows they were watching. Today, any music about country life and the love between a country boy and his girl is called western or country music.

    Frequently, we speak about people being “color-blind” but very few of us are. Even those who describe themselves as color-blind are normally just color lack. A strongly, color-blind person will still be able to tell 20 different colors, compared to the 100 or so that normal-sighted people see.

    Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a genetic trouble. It is known as Color-blind Island because so many people who live on this remote island can only see black and white.

    Not being able to see colors is bad enough. But one islander, Herrol, who's a fisherman, also struggles in full sunlight because all he sees is a painful burnt-out image. “I find it difficult to go outside in the sun,” he says, “because when it's sunny I cannot see to do my work.”

    But if being truly color-blind is rare, why is it that around 10% of the population of Pingelap live in a totally black and white world?

    Well, we know that in 1780 the population of Pingelap was all but wiped out by a tsunami (海啸). As few as 20 people survived, one of whom was the king. It's believed he had a genetic fault that causes colour-blindness and he passed this fault on to his many generations.

    There is one advantage. Herrol can see well, really well, in the dark. So when it gets dark, Herrol and his friends get in their boats and hunt flying fish. They hang up flaming torches and the fish are attracted to the flames. “This type of fishing is fun,” Herrol says, “especially if we catch plenty. So even though it's hard work we enjoy it.”

    It was May 23, 2016. Arnot, the 32-year-old mountain guide, reached the top of Everest without the use of oxygen (O2) equipment. It was achieved after seven years, three previous attempts, and fourteen straight hours of climbing.

After 15 minutes at the top, Arnot began her descent (下坡). Eight hours later, she reached the camp at 7, 600 meters and became the first American woman-and only the seventh woman ever—to successfully reach Mount Everest without oxygen equipment.

    "There are so many reasons for her impressive achievement, especially the physical and emotional efforts that she has put forth over the years to make this happen," says the professional climber and photographer Richards, "The mental courage that it requires is something very few people have."

    Arnot didn't start climbing until she was 19 years old. Money was tight in her family, and climbing mountains never occurred in her mind. After graduating from college, Arnot was invited by her friend to climb a mountain. "It totally changed my life," says Arnot. I always know that if you want something, you can achieve it, but knowing what you want is a whole different thing," she says. "I am athletic but not competitive. After my first climbing, I knew immediately that mountains are what I want—as that is where I felt home for the first time in my life."

    After that first climb, she devoted herself to learning how to climb and move through mountain. It was during her second trip to Everest in 2009 that she first set her sights on a no-oxygen attempt. However, while hiking into Everest Base Camp that year, she hurt her leg and wasn't able to climb without oxygen. In 2013 she nearly made it to the top, but was forced to take oxygen at 8,504 meters while helping another climber.

    When Arnot finally stood at the top Everest, she called her best friend, "I reached the top and I'm not using any oxygen." Then, tears began to stream down from her eyes. So much of Arnot's life has been about pushing the limits of her abilities, and in this case, she's also pushed up against the outer limits of the human spirit.

    Reality TV show has been charged with making the nation silly, but a study suggests part of the show could be good for children.

    Massey University PhD student Jacinta Hawkins looked at the influence of TV programs on kids' health knowledge, attitudes and behavior. She said programs which showed overweight people on TV is making children say "I don't want to grow up like that'."

    The research was part of Ms Hawkins' paper on how schools improve health. She spoke to 92 children, ages from 7 to 13, from six Auckland primary schools to find out how they received information on nutrition and physical activity. Some said they learnt from TV news programs, but most of them mentioned reality shows such as Fat Chance, Honey We're Killing the Kids and Downsize Me.

    "Earlier studies had looked at the effect junk-food advertising had on children," Ms Hawkins said, "but messages within TV programs had not been explored. Children from the six schools largely recognized program content, rather than advertising, as a source of food and physical activity messages. They are learning habits of eating and exercise from TV programs. "

    The children also recognized that their parents had a role to play in shaping health behavior. Talking about Honey We're Killing the Kids, which shows how people will look if they continue with good habits, children said they developed attitudes from their family's habits. MMs Hawkins said children remembered what they had seen and thought it was the parents' duty to lead by example.

Tropical cyclones (热带气旋), including hurricanes and typhoons, are now moving at a slower speed than they did decades ago, new research shows.

While having a cyclone travel with less speed may seem like a good thing, it's actually just the opposite. Wind speeds within the storm remain high, but the whole system itself moves slower, allowing punishing rains to stay longer over communities. "Nothing, good comes out of a slowing storm," says James Kossin, author of the paper. "It can increase the amount of time that buildings suffered from strong wind. And it increases rainfall."

In his paper, Kossin showed that from 1949 to 2016, tropical cyclones across the globe slowed their movement by 10 percent on average. In some regions (地区), the speed of those storms slowed even more as they hit land. In the western North Pacific, the decrease was much more manifest ― almost a third. That means a storm that may already hold more moisture (水分) will have time to drop more of it in each spot.

Kossin's work was based on details of almost 70 years' worth of storms, but he didn't try to determine what was causing the slowdown. Still, the change is exactly what he and other cyclone experts said, which would be expected from climate change. With the polar regions warming fester than other parts of the globe, that is changing the pressure and reducing the winds that push these storms.

Christina Patricola, a scientist, called Kossin9s work important and new and said she found it reliable. "I was not surprised by his findings," she says. "But I was surprised by the speed of the slowdown."

Kossin hopes that scientists will begin building models that show which places are likely to face the most risk. Given that storms in some regions are moving towards polar regions and already increasing in intensity (强度), cyclones causing unusually powerful rain may threaten places not normally in their paths. Scientists must take action to make those places suffer less from the disasters.
