If you're 70 and overweight, you may live longer
A few extra pounds might help you live longer if you're past your prime(壮年) but otherwise healthy, a new study finds.
Physicians routinely follow guidelines issued by the World Health Organization. Because weight depends on height, they use a standard measure called body mass index (BMI), which is calculated as the weight in kilograms divided by the height in meters squared.
Healthy weight is defined as a BMI anywhere between 18.5 and 24.9 in adults, whereas 25 to 29.9 is overweight and 30+ is obese.
The new study suggests that in the elderly, these boundaries may be too narrow. While no one is questioning that extra fat poses health risks in young and middle-aged adults, it may reduce the impact of frailty and old age, geriatrician(老年医学专家) Dr. Thomas Yoshikawa told Reuters Health.
So far, nobody knows exactly how BMI affects lifespan in older people. Some researchers speculate that it acts as an energy reserve that can help the elderly cope with illness.
For the study, Australian researchers followed more than 9,000 men and women who were between 70 and 75 years old at the beginning. The participants reported their height and weight as well as various factors related to health and lifestyle. about 33 percent of the women and 44 percent of the men were overweight.
Over 10 years, more than 2,000 of the participants died. Women who had an active life and didn't smoke were the most likely to be alive at the end of the study.
But neither health nor lifestyle could fully explain why overweight people of both sexes survived longer than their normal-weight peers, who fared no better than obese individuals. In terms of survival, the best BMI was between 26 and 27, well within the overweight range.
The new results agree with earlier research showing that fat may be beneficial in old age.

生活感悟类的文章就是指能给人心灵以启迪，使人从中受到教育的文章。这类文章的体裁可以是记叙文，如生活中一些感人故事或情感故事，有点类似心灵鸡汤一样的短文。有时故事的结尾会有一句“点睛之笔”，点出全文的中心思想，就像《伊索寓言》里的寓言一样。还可能是夹叙夹议的哲理散文或生活随笔。散文随笔通常会阐述一种朴素易懂，耳熟能详的人生道理或宝贵品质。文章的结构和议论文类似，一般是总分总或总分结构。每段首句或尾句为主题句（论点），其它句子围绕主题展开论述（论据），论证方法多种多样，或举例，或引用名言，或正反对照等。

针对生活感悟类文章的特点，做这类文章的完形填空时，要特别注意以下几点：
1、重点理解全文的首句。如果是记叙文，找出when，where，who，what等基本要素。如果是散文随笔，充分理解文章的中心句—全文的主题。
2、阅读全文的结尾段或结尾句，有助于理解文章所阐述或蕴含的哲理、感悟或忠告等。
