　　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(猛獸)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(圈養(yǎng))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(伐木場),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(肥胖癥)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.

　　41.Unlike other animals in zoos,zoo-raised elephants

　　A.live a long life.

　　B.give birth to many babies.

　　C.develop poor health.

　　D.have difficulty getting food.

　　42.Which of the following about the scientists'study is NOT true?

　　A.They compared zoo-born elephants with wild elephants.

　　B.They analyzed the records of 800 elephants kept in zoos.

　　C.The zoo-born elephants they studied were kept in European zoos.

　　D.They kept detailed records of all the elephants in their care.

　　43.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.

　　44.One of the possible reasons for the zoo-raised elephants'problems is that

　　A.they do not get proper food.

　　B.they do too much exercise.

　　C.they live in large herds.

　　D.they do not live in family groups.

　　45.It can be inferred from the last paragraph that

　　A.zoo-born elephants should be looked after more carefully.

　　B.zoos should keep more animals except elephants.

　　41.C 題意：不像動(dòng)物園內(nèi)的其他動(dòng)物，園內(nèi)飼養(yǎng)的大象_________。

　　題干中的關(guān)鍵詞為“unlike不像;zoo-raised elephants動(dòng)物園飼養(yǎng)的大象。”

　　根據(jù)文中第2段的1—2行：“科學(xué)家們已經(jīng)發(fā)現(xiàn)動(dòng)物園內(nèi)的大象面臨著很多的健康問題。”以此判斷應(yīng)選C項(xiàng)。

　　42.D 題意：有關(guān)科學(xué)家們的研究，下列哪一項(xiàng)不真實(shí)?

　　題干中的'關(guān)鍵詞為“thescientists'study科學(xué)家們的研究;NOTtrue不真實(shí)。”

　　A項(xiàng)在3段的1—3行;B項(xiàng)和C項(xiàng)在3段的5—6行。是“動(dòng)物園”而不是“科學(xué)家們”保留了詳盡紀(jì)錄，因此該題應(yīng)選D項(xiàng)。

　　43.C 題意：已發(fā)現(xiàn)，與野生雌性大象相比，園內(nèi)所生雌性大象……。

　　題干中的關(guān)鍵詞為“comparedwith與…相比較;female wild elephants野生雌性大象;female zoo- born elephants園內(nèi)所生雄性大象。”

　　根據(jù)文中第4段的1—3行研究小組發(fā)現(xiàn)，動(dòng)物園出生的非洲雌象平均壽命是16.9年。而自然死亡的野生大象平均壽命是56年，是動(dòng)物園大象的3倍多。”以此判斷應(yīng)選C項(xiàng)。

　　44.D 題意：動(dòng)物園內(nèi)飼養(yǎng)大象所存在問題的一個(gè)可能原因是_________。

　　題干中的關(guān)鍵詞為“reasons原因;the zoo-raised elephants'problems園內(nèi)飼養(yǎng)大象的問題

　　根據(jù)文中第5段的最后一句：“動(dòng)物園大象的社會(huì)生活也很不同，不像野生大象那樣過著群居的生活。”以此可以判斷應(yīng)選D項(xiàng)。

　　45.C 題意：從最后一段可以推斷出_________。

　　題干中的關(guān)鍵詞為“beinferred from從……可以推斷出;the last paragraph最后一段。”

　　最后一段“該項(xiàng)研究提出了是否應(yīng)該把更多的大象關(guān)在動(dòng)物園內(nèi)的問題雖然…似乎大象并非如此。”以此判斷應(yīng)選C項(xiàng)。
