单选题Like fine food, good writing is something we approach with pleasure and enjoy from the first taste to the last. And good writers, like good cooks, do not suddenly appear full-blown. Quite the contrary, just as the cook has to undergo an intensive training, mastering the skills of his trade, the writer must sit at his desk and devote long hours to achieving a style in his writing, whatever its purpose—school work, matters of business, or purely social communication. You may be sure that the more painstaking the effort, the more effective the writing, and the more rewarding. There are still some remote places in the world where you might find a public scribe to do your business or social writing for you, for a fee. There are a few managers who are lucky enough to have the service of that rare kind of secretary who can take care of all sorts of letter writing with no more than a quick note to work from. But for most of us, if there is any writing to be done, we have to do it ourselves. We have to write school papers, business papers or home papers. We are constantly called on to put words to paper. It would be difficult to count the number of such words, messages, letters, and reports put into the mails or delivered by hand, but the daily figure must be enormous. What is more, everyone who writes expects, or at least hopes, that his writing will be read. We want to arouse (引起) and hold the interest of the readers. We want whatever we write to be read, from first word to last, not just thrown into some "letters-to-be-read" file or into a wastepaper basket. This is the reason we bend our efforts toward learning and practicing the skills of interesting, effective writing.

单选题 A study of nearly 140 000 women in the US showed that regular helpings of a small portion of nuts can have a powerful protective effect against a disease that is threatening to become a global epidemic. Women who consumed a 28 gram packet of walnuts at least twice a week were 24 percent less likely to develop type 2 diabetes than those who rarely or never ate them. Eating walnuts just two or three times a week can reduce the risk of type 2 diabetes by almost a quarter. The latest findings, published in the Journal of Nutrition, are not the first to highlight the anti-diabetic effects of walnuts, with earlier research showing similar benefits. However, this is thought to be one of the largest studies to find regularly snacking on them can help prevent the condition. Although the latest research was carried out on female nurses, it's likely that the same benefits apply to men. According to the charity Diabetes UK, at the current rate of increase, the numbers affected by type 2 diabetes in the UK will rise from around 2.5 million currently to four million by 2025 and five million by 2030. Left untreated, it can raise the risk of heart attacks, blindness and amputation (截肢). Being overweight, physically inactive and having a poor diet are major risk factors for the disease. Scientists at the Harvard School of Public Health in Boston, US, tracked 137893 female nurses aged from 35 to 77 over a ten year period to see how many developed type 2 diabetes. Their dietary habits were closely monitored, including details on how often they ate nuts, particularly walnuts. After allowing for body fat and weight, the researchers found eating walnuts one to three times a month reduced the risk by four percent, once a week by 13 percent and at least twice a week by 24 percent. In a report on the findings the researchers said: 'These results suggest higher walnut consumption is associated with a significantly lower risk of type 2 diabetes in women.' Walnuts are rich in healthy fatty acids (脂肪酸) which have been shown to reduce inflammation (炎症) in the body and protect against heart disease, cancer and arthritis (关节炎). Last year, experts at the University of California Los Angeles also found young men in their twenties and thirties who ate walnuts every day increased their sperm count and boosted their fertility. The research comes just after a Louisiana State University study which showed that eating nuts can reduce people's risk of obesity. The study found that those who consumed varieties such as almonds and pistachios (开心果) demonstrated a lower body weight, body mass index (BMI) and waist circumference compared to non-consumers. They were also at lower risk of developing heart disease, type 2 diabetes and metabolic syndrome.
