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,illnes-
ses,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 fe-
male 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一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 coun-
terparts.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.
It was found that,compared with female wild elephants,female zoo-born elephants_______________.
A:lived longer
B:grew up faster
C:died much earlier
D:enjoyed the same life spans

Most people think of zoos as safe heavens for animals, where problems such as difficulty finding food and avoiding predators （食肉动物) don’t exist. Therefore, animals in zoos should live to a ripe 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. They develop diseases and they are even unable to have babies. To learn more about how captivity （圈养) affects elephants, a team of international scientists compared the lifespans （寿命) of the zoo-born elephants with the lifespans of thousands of wild elephants. They also compared some Asian elephants living in zoos with some Asian elephants which work in logging camp （伐木场), over almost the same time period. The team found that elephants born in zoos lived an average of 16.9 years, but elephants that died of natural causes lived an average of 56 years. Asian elephants followed a similar pattern. In zoos, they lived 18.9 years, while those in the logging camp lived 41.7 years. Scientists don’t yet know why wild elephants seem to live so much better than their zoo-raised counterparts （同类). Georgia Mason, a biologist at the University of Guelph in Canada, who led the study, thinks stress and obesity （肥胖) may be to blame. Zoo elephants don’t get the same kind of exercise they would in the wild. Elephants’ social lives are also much different in zoos than in the wild, where they live in large family groups. 小题1:Most people believe that________.
A．animals in zoos should live a longer life
B．zoos are not good for animals to live in
C．zoos are not suitable for large animals
D．captivity can affect animals in many ways小题2:The purpose of the international scientists is_____.
A．to compare the lifespans of different animals
B．to find out how captivity affects elephants
C．to learn the lifespans of male and female elephants
D．to compare the lifespans of elephants in different places小题3:Which elephants live the longest according to the study？
A．Elephants born in zoos.
B．Elephants that live in the wild.
C．Elephants that work in logging camps.
D．Female Asian elephants in logging camps.小题4:We can infer from the passage that_____.
A．elephants in zoos suffer less stress than those in the wild
B．elephants in zoos live an easy life
C．social lives are not important to elephants
D．zoo life can be stressful to elephants小题5:What are the advantages to elephants in the wild according to the passage？
A．They face fewer problems.
B．They can find food more easily.
C．They live in large social groups.
D．They are freer to move.
