To get an extra 14 years of life, don’t smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn’t．
“We’ve known for a long time that these behaviors are good things to do, but we’ve not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain’s Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”
Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
“We can’t say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what’s theoretically（理论上地）possible．”
“Most people know that things like a good diet matter and that smoking isn’t good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”

(答案→)D【小题1】A【小题1】C【小题1】C
解析：
【小题1】第一段第一句话已列出健康的生活方式是don’t smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount，与四个选项对比后可得知D项的睡前吸烟不是健康生活方式。所以选D。
【小题1】从第三段第二行的Susan Jebb, head of Nutrition and Health at Britain’s Medical Research Council可得知Susan Jebb并非是该研究的发起者University of Cambridge的一员，所以她并未参与此研究。所以选A。
【小题1】最后一段的最后一句话We need to work on providing people with much more practical support to help them change告诉我们本文是在呼吁社会帮助人们改掉坏习惯，其他三个选项均不全面。所以选C。
【小题1】这一题可以从原文第一段第一句话To get an extra 14 years of life得出选择C，其次C选项中的may也和文章正在研究中不是非常确定的态度相吻合。所以选择C。
