    Ao falar da relação entre linguagem e mundo, o professor José Carlos Azeredo (2007) ressalta que a linguagem não é uma simples ferramenta ou instrumento, tampouco o espelho de um mundo de objetos e fenômenos, porque o que nossos textos significam resulta da filtragem e modelação de nossas experiências; em outras palavras, a transformação de nossas experiências de mundo em matéria textual envolve fatores socioculturais de propriedade coletiva.

    Why don’t we take our own advice?
    Oliver Burkeman

    “Why is it so hard to take your own advice?” the psychology writer Melissa Dahl asked in a New York magazine essay some months ago, and the question’s been bugging me ever since. I have the arrogance to imagine that if you followed some of the suggestions made each week in this column, you might be a little happier or more productive, with a little less relationship drama, a little more inner calm. (From my email inbox, I know this happens at least occasionally.) But were you to infer from this that I follow such advice flawlessly myself, you’d be mistaken. When friends mention their difficulties with partners or bosses, Dahl wrote, she always tells them to talk to the person involved. Just say something! “And probably, this is good advice,” she mused. “I wouldn’t know, as it’s something I rarely do myself.” I can understand. I suspect most of us can. As the old wisecrack has it: “Take my advice – I’m not using it.”
    The cynical take on this is that we ignore our own advice because it’s rubbish: we give it to seem wise, when in fact it’s nonsense. (All advice to “try harder” or “snap out of it” or “look on the bright side” fall into this category: if the recipient could do so, he or she already would have, without your so-called help.)
    But a more interesting notion is that the advice is often good – yet something prevents us applying it to ourselves. One such obstacle is simply too much information: inside our own heads, we have access to all manner of details, making us believe that this relationship problem, this job dilemma, is special, so the advice doesn’t apply. Dahl cites work by the psychologist Dan Ariely, showing that when a friend gets a serious medical diagnosis, most people would urge them to get a second opinion. But were it to happen to themselves, they’d be more likely not to do so, for fear of offending their doctor. The fear of offence is something you’d think of only in your own case – and it’s totally unhelpful.
    But there’s another big reason I don’t follow my own advice: the huge gulf between grasping something intellectually and really feeling it in your bones. For example, it was years ago that I first encountered the insight that anxiety and insecurity aren’t reduced by trying to exert more control over the world; in fact, that usually makes them worse. I know this. But apparently I have to keep learning it, over and over. Its correctness isn’t sufficient for it to get into my brain once and for all; that takes repeated experience. As a result, I continue to “suddenly realise” things I already wrote an entire book about.
    If nothing else, this should be a caution against getting too frustrated with that one friend of yours who keeps getting into the same kind of pickle, time and again, deaf to the obviously good advice that everyone keeps offering. You know the type. We’ve all got a friend like that. The 
    scary thought is that, for some of your friends, it’s probably you.

                               Alice Munro’s road to Nobel literature prize was not easy

                                                       Imagem da questão de Inglês, CEDERJ 2014, Interpretação de texto | Reading comprehension

                                             Nobel literature prize winner Alice Munro.

    Alice Munro has been awarded the 2013 Nobel Prize in literature, thus becoming its 13th female recipient. It’s a thrilling honour for a major writer: Munro has long been recognised in North America and the UK, but the Nobel will draw international attention, not only to women’s writing and Canadian writing, but to the short story, Munro’s chosen literary genre and one often neglected.

    The road to the Nobel wasn’t an easy one for Munro. She found herself referred to as “some housewife”, and was told that her subject matter, being too “domestic”, was boring. A male writer told her she wrote good stories, but he wouldn’t want to sleep with her. “Nobody invited him,” said Munro. Maybe as a consequence of this initial reaction towards her, when writers occur in Munro stories, they are pretentious, or exploitative of others; or they’re being asked by their relatives why they aren’t famous, or – worse, if female – why they aren’t better-looking.

    The chances that a literary star would emerge from her time and place would once have been zero. Munro was born in 1931, and thus experienced the Depression as a child and the Second World War as a teenager. This was in south-western Ontario, Canada, a region that also produced equally talented writers and poets such as Robertson Davies, Graeme Gibson, James Reaney, and Marian Engel. It’s this small-town setting that features most often in her stories – the snobberies, the eccentrics, and the jeering at ambitions, especially artistic ones.

    Shame is a common driving force for Munro’s characters just as perfectionism in the writing and courage in her profession have been driving forces for her.

    As in much else, Munro is essentially Canadian. Faced with the Nobel, she will be modest, she won’t get a swelled head. The rest of us, on this magnificent occasion, will just have to do that for her.

                                 Why I took up the cello in my 60s

    Michelle Hanson

    Learning to play a musical instrument at any point in life is good for the brain. Who cares if I sound like a 'sick cow'?

                                       Imagem da questão de Inglês, CEDERJ 2013, Interpretação de texto | Reading comprehension

    It's exciting to know that I have done something right and rewarding – taking up the cello in my 60s. A new study from St. Andrew's University proves it. Taking up a musical instrument, even late in life, is good for the brain, and “can slow, stop, or even reverse, age or illness-related decline in mental functions". Hurrah!

    My efforts have been rewarded, because starting the cello was a bit of a struggle, physically and mentally. Back then, my mother was alive, and rather critical: “You sound like a sick cow," she would cry out in a tormented way, but I persisted, joined an orchestra, and now here I am, with a bigger frontal cortex area than I might have otherwise had, and able to “adjust my behaviour more effectively in conflict-rich situations".

    The more you practise the better, suggests the research. Good. It will spur me on, sick cow or not. Because I desperately need to keep my brain in order. Don't we all, if we're going to live to over 100? Last week I went for a walk with an old friend of mine and her dog. She is 92 and browned off.

    “How are you?" I asked. “Fed up. I want to die." This was my mother's primary aim once she hit 96. “What do you want for your birthday?" we would ask. “To be dead!", she would say. No wonder. What else did life offer? At least my old friend could walk about. My mother could hardly walk, talk or eat.

    If only they had played a musical instrument. You can do it sitting down, on your own, with friends, cheer yourself up, be in control, or wildly emotional. I cannot recommend it highly enough.
