理工 第三十八篇 Longer Lives for Wild Elephants(B级) Most people think of zoos as safe places for animals，where struggles such as difficulty finding food and avoiding predators食肉动物 don't exist. Without such problems, animals in zoos should live to a ripe old age l．

人们通常认为动物园对于动物来说是安全的，因为他们没有猎食的困难，也不受其他肉食动物的威胁，所以动物园内的动物应该寿命较长。

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．They develop diseases，joint problems and behavior changes．Sometimes, they even become infertile不生殖, or unable to have babies婴儿．

但世界上最大的陆地动物却并非如此。科学家已经发现大象面临着很多健康问题，例如生病、关节问题和行为改变等，有时甚至会失去生育能力。

To learn more about how captivity affects elephants, a team of international scientists compared the life spans of female elephants born in zoos with female 3

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 elephants with the life spans of thousands of female wild elephants in Africa and Asian elephants that work in logging camps3，over approximately the same time period． The team found that female African elephants born in zoos lived an average of l 6.9 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 l 8．9 years, while those in the logging camps lived 41.7 years． Scientists don't yet know why wild elephants seem to fare 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 may be to blame4．Zoo elephants don't get the same kind of exercise they would in the wild，and most are very fat．Elephant social lives are also much different in zoos than in the wild，where they live in large herds and family groups． Another finding from the study showed that Asian elephants born in zoos were more likely to die early than Asian elephants captured in the wild and brought to zoos．Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive． The study raises some questions about acquiring more elephants to keep in zoos．While some threatened and endangered species living in zoos reproduce successfully and maintain healthy populations，that doesn't appear to be the case with elephants．"Currently，zoos are net consumers of elephants，not net producers，" Mason says． 练习： 1．According to the first two paragraphs，unlike other zoo animals，zoo elephants A．have difficulty eating food． B．1ive to a ripe old age． C：are not afraid of predators． D．develop health problems．

2．Which of the following about the international scientists' research on the life spans of elephants is NOT true? (See paragraph 3)? A．They compared zoo elephants with wild elephants． B．They kept detailed records of all the elephants in their care． C．They analyzed the records of the elephants kept in zoos． D．The zoo-born elephants they studied are kept in European zoos．
