Longer Lives for Wild Elephants
Most people think of zoos as safe places for animals， where struggles such as having difficulty finding food and avoiding predators （猛兽） don"t exist. Without such problems， animals in zoos should live to a ripe （成熟的） old age.
But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often suffer from poor health. Sometimes， they even become unable to have babies.
To learn more about how captivity （圈养） affects elephants， a team of international scientists compared the life spans of female elephants born in zoos with female elephants living outdoors in their native lands. Zoos keep detailed records of all the animals in their care， documenting factors such as birth dates， illnesses， weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 African and Asian elephants in zoos across Europe. The scientists compared the life spans of the zoo-born female elephants with the life spans of thousands of wild female elephants in Africa and Asian elephants that work in logging camps （伐木场）， over approximately the same time period.
The team found that female African elephants born in zoos lived an average of 16.9 years.
Their wild counterparts who died of natural causes lived an average of 56 years——more than three times as long. Female Asian elephants followed a similar pattern. In zoos， they lived 18.9 years，while those in the logging camps lived 41.7 years.
Scientists don"t know yet why wild elephants seem to get on so much better than their zoo-raised counterparts. Georgia Mason， a biologist at the University of Guelph in Canada who led the study，thinks stress and obesity （肥胖症） may be to blame. Zoo elephants don"t get the same kind of exercise they would in the wild， and most are very fat. Social lives of elephants are also much different in zoos than in the wild， where they live in large herds and family groups.
The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce （生殖） successfully and maintain healthy populations， that doesn"t appear to be the case with elephants.
Unlike other animals in zoos， zoo-raised elephants __________ . 查看材料

Style， Not Fashion
Style. goes way beyond fashion: It is the distinctive way we put ourselves together. It is a unique blend of spirit and substance-personal identity imposed oil and created throughthe world of things. ___________ （46）. It is what people really want when they aspire to be fashionable. （if they aren"t just adorning （装饰） themselves in status symbols）.
Through clothes， wereinvent ourselves every time we get dressed. Our wardrobe is our visual vocabulary. Style. is our distinctive pattern of speech， our individual poetry.
Fashion is the least of it. Style. is， for starters， one part identity: self-awareness and self-knowledge. ___________ （47）. And style. requires security-feeling at home in your body，physically andmentally. Of course， like all knowledge， self-knowledge must be updated as yougrow evolve; style. takes ongoing self-assessment.
Style. is also one part personality: spirit: verve， attitude， wit， inventiveness. It demands the desire and confidence to express whatever mood one wishes. Such variability is not only necessary but a reflection of a person"s unique complexity as a human being. ___________ （48）. In order to work， style. must reflect the real self， thecharacter and personality of the individual; anything less appears to be acostume？
Lastly， style. is one partfashion. It"s possible to have lots of clothes and not an ounce of style.
But it"s also possible to have very few clothes and lots of style. Yes， fashion is the means through which we express style， but it takes fewer clothes to be stylish than you might imagine.
Whatever else it is， style. is optimism made visible. Style. presumes that you are a person of interest: that the world is a place of interest that life is worth making the effort for. It also shows that you are morally responsible. It shows that you don"t buy things at the whim （突然的念头） of the market place or the urging of marketers. ___________ （49）. Style. exposes people"s ambivalence（矛盾心理） over good looks. It always demonstrates that appearances do count. Deep down we suspect this， since we ourselves make judgments about others from how they look.
No one should be penalizedfor not having style， of course， but those who have it are distinctive and thus more memorable. ___________ （50）. They announce to the world that they are in command of themselves.
