问题 Global life expectancy averages out to 71.4 years. That means, of course, that some parts of the world see much shorter life spans, while others enjoy far greater longevity. Five places, in particular, fall into the latter category. They’re known as Blue Zones—named for the blue circles researchers drew to identify the first one on a map—and they’re home to some of the oldest and healthiest people in the world. Dan Buettner, author of The Blue Zones and The Blue Zones Solution, told TIME why residents of these places live so long—and how you can steal their habits.
SARDINIA, ITALY
A largely plant-based diet, daily physical activity and familial closeness have given this Blue Zone the highest concentration of male centenarians in the world. (Sheep herders, who tend to walk at least five miles a day, and men with daughters, who may get especially tender care as they age, live even longer than most in this area.) It also doesn’t hurt that the M26 marker, a genetic variant linked to extreme longevity, has been passed down through generations in this secluded community.
OKINAWA, JAPAN
Many Blue Zones emphasize family and community, but bonding reaches its peak in this Japanese culture. Okinawans are supported by their moai, a small but tight-knit social circle meant to be there through all of life’ s ups and downs, which provides social support strong enough to dull mental stressors and reinforce shared healthy behaviors. The result? A culture that boasts the longest-living women in the world, with many surpassing 100.
NICOYA, COSTA RICA
Most Blue Zone residents avoid processed food, but Nicoyans take it to another level. The Costa Rican people traditionally get the majority of their caloric intake from beans, squash and corn, plus tropical fruits. This plant-forward, nutrient-dense diet—and plenty of time outdoors—makes for strong, well-nourished bodies. Meanwhile, a plan devida, or guiding life purpose, helps Nicoyans stay mentally and spiritually fulfilled to age 90 and beyond.
LOMA LINDA, CALIF., USA
The U.S. ’s only Blue Zone is a haven for the Seventh-day Adventist Church, a Protestant denomination. A shared set of principles, emphasis on community and adherence to the Sabbath—a day of rest, reflection and recharging—Many avoid meat and eat plenty of plants, whole grains and nuts help Loma Linda Adventists live 10 years longer than their fellow Americans.
IKARIA, GREECE
A fierce sense of island pride keeps Ikarians invested in their community. That, combined with late bedtimes offset by daily naps and a strict adherence to the Mediterranean diet—eating lots of fruits, vegetables, beans, whole grains, potatoes and olive oil—propels 1 in 3 Ikarians to live into their 90s, often free of dementia and chronic disease.
Why do people in blue circles have greater longevity?
选项 A、Because people usually live in the form of community.
B、Because people only eat plenty of plants and avoid meat.
C、Because people have a rest all the year.
D、Because people live in cold zone environment.
答案A
解析 推断题。题干大意为：为什么生活在蓝圈的人们寿命更长?分析各个选项可知，A项意为“因为人们通常以社区形式居住”，B项意为“因为人们只吃各种蔬菜，不吃肉类”，C项意为“因为人们全年休息”，D项意为“因为人们居住在寒带环境中”。根据全文大意可知，五个地区的人们长寿的共同点都是采用社区形式生活。长寿的人大都以蔬菜、谷物、水果等为食，B项中only一词可以排除。C项谈到休息，可以定位到第五段，美国加州的人遵从着一套共同的原则，他们重视社区，重视对安息日的贯彻——用这一天来休息、反思和充电——这些做法让罗马琳达复临信徒比他们的美国同胞长寿了10年，而非C项提到的全年都休息。D项人们都住在寒带地区这一说法是错误的。这里涉及的五个地方不属于寒带地区，意大利属于亚热带，日本属于温带气候，哥斯达黎加属于热带和亚热带，美国加州属于亚热带，希腊属于温带。故选A。
