Peter Byford was born in a stone house in Honley，and when he was tiny his dad，a former miner，got a job in the textile trade and the Byford's moved to Skelmanthorpe.Life was tough but fun，and young Peter spent his days in the rolling countryside，rafting on the river，making tree camps or playing on his own with his model railway and soldiers.

     His world was rocked by tragedy when his mother died，which destroyed young Peter，a shy child who suddenly had to grow up fast.Though grieving，he went up the road to live with his aunt and uncle，and returned home much too young to face the next challenge，that of looking after his dad，who had lost an arm in an accident in a factory.

     By then he had taken the nickname as Biff.The younger Biff struggled at school because of his shyness，but loved the music lessons and became friends with a classmate whose brother had a guitar.At the same time a young man who had a banjo(班卓琴)moved into the house opposite where he lived and he taught young Biff how to play it.The seeds had been sown and music began to influence his life.

     But even so，his working career began，in typical fashion for 1960s West Yorkshire.After a short time as an apprentice(学徒)carpenter，he went to work in the local weaving factory.And this was where Biff Byford，soon to become a legend in the world of rock，first learned to sing.The machines would run all day，clickety­clack，clickety­clack.The noise was incredible，and the workers would spend their time trying to lip read each other.

     It was just so noisy in there.It was really heavy metal.The only thing to do was sing to yourself.So sing to himself he did，the melodies(旋律)locking in place in his head，not to be forgotten.His dream first exploded into a rocking reality.

    Are we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are.  You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she would be one of the brightest among us,” Crabtree told The Guardian.

    At the heart of Crabtree's thinking is a simple idea. In the past, intelligence was critical for survival when our ancestors had to avoid dangerous animals and hunt for food. The difference of being smart or stupid is often life or death. However, after the spread of agriculture, when our ancestors began to live in dense ( 稠密的）farming communities, the need to keep their intelligence in peak condition gradually reduced. This is not hard to understand. Most of the time,pressure is what keeps us going – you need the pressure from your teachers to finish your homework; the pressure of looking pretty prompts(促使) you to lose weight when summer comes. And the same is also true of our intelligence – if we think less, we become less smart.

    These mutations(变) are harmful to our intelligence and they were all developed in the past 3,000 years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to 5,000 genes that we have that determine human intelligence , there are two or more mutations in each of us. However, Crabtree's theory has been criticized by some who say that early humans may have better hunting and surviving abilities, but people today have developed a more diverse intelligence. For example, spearing a tiger doesn't necessarily require more brainpower than playing chess or writing a poem. Moreover, the power of modern education means a lot more people have the opportunity to learn nowadays. “You wouldn't get Stephen Hawking 2,000 years ago. He just wouldn't exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights(洞察力) that we would never have achieved in our environment of evolutionary adaptation.”

    When I was about 12, I had an enemy, a girl who liked to point out my shortcomings (缺点). Wee k by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, then he asked. “Are the things she says true or not? Janet, didn't you ever wonder what you're really like ? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I went to a fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it. “That's just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”

    Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    Galdwell's book, Blink, is all about first impressions and what he calls “rapid cognition（认知）”. In his own words, “It's a book about the kind of thinking that happens in a short time. When you meet someone for the first time or read the first few sentences of a book, your mind takes about two seconds to jump to a series of conclusions.”

    Galdwell points out that most scientific tradition is based on a great deal more than two seconds' thought though years of scientific study can come from a quick observation. As for rapid cognition, Gladwell realizes some first impressions don't seem to be based on anything. He noticed that Americans support taller candidates（候选人）. In fact, since 1900, only four candidates have beaten men who are taller than themselves. With this in mind Gladwell got in touch with 500 companies in the US and found that almost all of their managers were tall. Gladwell said, “That's weird. There is no connection between height and intelligence or height and decision-making…But for some reason companies chose tall people for leadership roles. I think that's an example of bad rapid cognition.”

    As an example of good rapid cognition, he tells the story of the Emergency Room doctors at Cook County Hospital in Chicago. A few years ago, the hospital changed the way they diagnosed（诊断）heart attacks. Their doctors took no notice of the patient's age, weight and medical history and gave most of their attention to a few really important pieces of information, such as blood pressure and heart rate. And what happened? Cook County is now one of the best places in the United States for diagnosing chest pain.

    Gladwell believes the power of first impressions should be studied further. “The first task of Blink is to show the fact: decisions made very quickly can be as good as decisions made slowly and carefully.”

    Once upon a time, there was a lovely vegetable field, on which grew a very thick tree. Both the vegetables and the tree gave the place a wonderful appearance, which was the joy of the garden's owner. What no one knew was that the vegetables in the field and the tree couldn't stand each other. The vegetables hated the tree's shadow, because it left them only just enough light to survive. The tree, on the other hand, hated the vegetables because they drank nearly all the water before it could get to him, leaving him with just enough to survive.

    The situation became so extreme that the vegetables got totally fed up and decided to use up all the water in the ground so that the tree would dry up. The tree answered back by refusing to give the vegetables shadow from the hot midday sun, so they both began to dry up. Before long, the vegetables were really thin and the tree's branches were drying up.

    Neither of them thought that the gardener, on seeing his vegetable field becoming worse, would stop watering it. When he did that, both the tree and the vegetables really learned what thirst was. There seemed to be no solution, but one of the vegetables, a small courgette（小胡瓜）, understood what was going on, and decided to deal with it. Despite the little water and the unbearable heat, the little courgette did all he could to grow, grow... He managed to grow so big that the gardener started watering the field again. The gardener wanted to enter that beautiful big courgette in some gardening contest.

    They should really learn how to live in harmony）with those around them, doing the best they could. So they decided to work together, and help each other instead of fighting, using both the shadow and the water in the best combination to grow good vegetables. Seeing how well they were doing, the gardener now gave the best of care to his vegetable field, watering it better than any other field for miles around.

Having a study partner has many advantages. Of course, you can always study alone at home. But you'll miss the benefits that come from learning with a friend or two. Why should you think of finding a study partner or a study group? {#blank#}1{#/blank#}

It can reduce distractibility(注意力分散).

Staying focused is one of the biggest challenges students have to overcome. When you have a study partner, it will be easier to achieve. With common goals in mind, you will focus on the result. 

You understand the material faster than alone.
