At thirteen, I was diagnosed(诊断) with a kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.

    In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it.” She glanced down at me through her glasses, “You are no different from your classmates, young man.”

    I tried, but I didn't finish the reading when the bell rang. I had to take it home.

    In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots(点), which opened up a whole new world of knowledge to the blind.

    Wasn't I the “blind” in my class, being made to learn like the “sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?

    I didn't expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day—with an “A” on it. At the bottom of the paper were these words: “See what you can do when you keep trying?”

    Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases with his students . The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems. His condition was not improving, and there was not much hope he would live.

    Dr. Mellinkoff asked to see the patient. He introduced himself in Spanish and, in a very gentle voice, asked how he felt. The patient smiled and said everything was all right. Then the doctor asked if he was able to eat. The patient said that he had no desire to eat.

    “ Are you getting food you like? ”

    The patient said nothing.

    “ Do you get the kind of food you have at home? ”

    The answer was no.

    The doctor put his hand on the man's shoulder and his voice was very soft.

    “If , you had food that you liked , would you eat it? ”

    “Yes , yes. ” the patient said.

    The change in the patient's appearance couldn't have been more obvious. Nothing was said, but it was easy to tell that a message had been sent and had also been received.

    Later, the doctor asked why the Guatemalan man wasn't getting food he could eat. One of the students said, “ We all know how difficult it is to get the kitchen to make special meals. ”

    “ Suppose, ” the doctor replied, “ you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request? ”

    “ I would probably insist, ” the student said.

    “ Very well, ” the doctor said. “ You might want to try the same method in the kitchen. It won't be easy, but I can help you. Meanwhile, let's get some food inside this man as fast as possible, and stay with it. Or he'll be killed by hunger. By the way, there must be someone among you who can speak Spanish. If we want to make real progress, we need to be able to talk with him. ”

    Three weeks later, Dr. Mellinkoff told me that the Guatemalan man had left the hospital under his own power. It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.

    Our love of music and appreciation of musical harmony (和声) is learnt and not based on natural ability, a new study by University of Melbourne researchers has found. The researchers said previous theories about how we appreciate music were based on the physical functions of sound, the ear itself and a born ability to hear harmony.

    The study shows that musical harmony can be learnt, and it is a matter of training the brain to hear the sounds. So if you thought that the music of some foreign culture (or Jazz) sounded like the crying of cats, it's simply because you haven't learnt to listen by their rules.

    The researchers used 66 volunteers with a range of (一系列的) musical training and tested their ability to hear combinations (组合) of notes (音符) to determine if they found the combinations familiar or pleasing. They found that people needed to be familiar with combinations of notes. If they couldn't recognize the notes, they found the notes dissonant. This finding put an end to centuries of theories claiming (声称) that physical functions of the ear determine what we find attractive.

    The study found that trained musicians were much more sensitive (敏感的) to unpleasant notes than non-musicians. When they couldn't find the note, the musicians reported that the sounds were unpleasant, while non-musicians were much less sensitive. This shows the importance of training or nurturing (培养) the brain to like particular sound of combinations of notes, like those found in jazz or rock.

    Depending on their training, a strange chord (和弦) sound was pleasant to some musicians, but very unpleasant to others. This showed us that even the ability to hear a musical note is learnt.

    To confirm (证实) this finding, they trained 19 non-musicians to find the notes of a random (随机的) selection of western chords. Not only did the participants' ability to hear notes improve rapidly; the chords they had learnt sounded more pleasant—regardless of (不论) how the chords were played.

    The question of why some combinations of musical notes are heard as pleasant or unpleasant has long been debated. “ We have shown in this study that for music, beauty is in the brain of the beholder(观看者),” a researcher said.

    Since my family were not going to be helpful about my taking a cooking job, I decided I would look for one all by myself and not to tell them about it till I'd got a permanent one.

    I had seen an agency advertised in a local paper, so as soon as there was no one about to say “Where are you going?” I rushed out of the house in search of it. I was wildly excited, and as nervous as if I were going on the stage. Finding the place quite easily, I tore up three flights of stairs, and swung breathlessly through a door which said “Enter without knocking, if you please.”

    The simple atmosphere of the office calmed me, and I sat down on the edge of a chair. The woman at the desk opposite looked carefully at me. Then she questioned me in a low voice. I answered softly and started to feel helpless. She wondered why I was looking for this sort of job, so I felt I had to give her the idea of a widowed mother struggling against poverty. But I felt more helpless when she told me that it would be difficult to get a job without experience or references. Suddenly, the telephone on her desk rang. While having a mysterious conversation, she kept looking at me. Then I heard her say:

    “In fact, I've got someone here who might suit.” She wrote down a number, and my spirits rose as she held out the paper to me, saying: “Ring up this lady. She wants a cook immediately. Cook a dinner for ten people tomorrow. Could you manage that, I wonder?”

    “Oh, yes,” say I—never having cooked for more than four. Then I rushed out and called the lady, Miss Cathy. I said confidently that I was just what she was looking for. “Are you sure?” she kept saying. Anyway she decided to employ me and a permanent position if I carried out the promise of my self-praise. I asked her what tomorrow's menu was to be.

    “Just a small, simple dinner: lobster cocktail, soup, turbot mornay, fruit salad and a savory.” In a rather shaken voice I promised to turn up in good time tomorrow and rang off.

    City people usually think they are a lot smarter than country people. They often laugh at simple country ways. But people do not laugh at country music. It is one of the most popular kinds of music in the United States today.

    Perhaps it is so popular because it is about simple but strong human feelings and events—love, sadness, good times and bad times, it tells real life stories and sounds the way people really talk. As life becomes more and more complicated(复杂的), it is good to hear music about ordinary people.

    Country music, sometimes called country western, comes from two kinds of music. One is the traditional music of the people in the Appalachian Mountains in the eastern United States. The other is traditional cowboy music from the West. The singers usually play the guitars, and in the 1920s they started using electric guitars.

    At first city people said country music was low-class. It was popular mostly in the South. But during World War Ⅱ, thousands of Southerners went to the Northeast and Midwest to work in the factories. They took their music with them. Soldiers from the rest of the country went to army camps in the South. They learned to like country music. Slowly it became popular all over the country.

    Today country music is popular everywhere in the United States and Canada, in small towns and in New York City, among black and white, and among educated and uneducated people. About 1,200 radio stations broadcast country music twenty-four hours a day. People sing it in their languages. The music that started with cowboys and poor farmers is now popular all over the world.

    We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置)well after they go out of style. That's bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life—from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s.Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992.Digital cameras arrived on the scene in 1997.And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones.“The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007.We're not just keeping these old devices—we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放)more than doubling during the 1992 to 2007 window.

    So what's the solution (解决方案)?The team's data only went up to 2007,but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
