14.Wildlife conservationists in Kenya are trying to save a rare kind of rhinoceros (犀牛).So many northern white rhinos have been hunted and killed that they are almost dying out.There were only five northern white rhinos left.So the workers hoped they could save the rhinos by helping them produce young.
Three northern white rhinos lived at The Ol Pejeta Conservancy (保护区) in Kenya.Workers with military weapons guarded the rhinos as they walked,played and ate over a large area of natural grass and trees.The three rhinos were brought to the conservancy in 2009from a zoo in the Czech Republic.Workers hoped they would have a better chance of survival in a more natural habitat.
But breeding has not been as successful as they had hoped.And the number of northern white rhinos continues to decrease.One of the rhinos at the conservancy died in October.Another died at a zoo in the US city of San Diego,California earlier this month.The San Diego zoo still has one northern white rhino left.The zoo in the Czech Republic also has one.
The last wild northern white rhinos were hunted and killed during conflicts in the Democratic Republic of Congo over the past ten years.Rhinos are killed because many people in Asia want the animals'horns (角).They believe the horns will help with medical problems.But researchers say there is no medicine in the horn,just a kind of hair.
The last male northern white rhino is 41years old.He has been unsuccessful in producing young with a female rhino.So conservationists will use artificial methods to make a young female become pregnant.If that is not successful,they will try to fertilize a northern rhino egg and put it into a southern white rhino,who will act as a surrogate(代孕) mother.The last solution would be cross-breeding between the northern and southern white rhino species.If cross-breeding is successful,there is hope that some part of the northern white rhino species may still live on.

A.To protect them from being killed by the armed guards.
B.To ensure that they live better in a natural environment.
C.To keep the conservation a good balance of nature.
D.To attract more visitors to come to this area.
33.In Paragraph 3,it's inferred that the number of the rhinos falls down toB.
A.1B.3C.5D.7
34.People hunted and killed rhinos becauseA.
A.they wanted to get rhinos'horns for medical use
B.rhinos ate natural grass and trees on their farmland
C.get rid of the threat of rhinos from their life
D.they wanted to do researches on producing young for rhinos
35.From the last paragraph,we can learn thatA.
A.other measures will be taken to breed rhinos
B.the conservationists lead a busy life in Congo
C.breeding a baby white rhino is quite an easy job
D.cross-breeding is an effective way to produce young.
分析 本文考察环境保护类短文阅读,主要向我们讲述了北部白犀牛由于人们的掠杀现在几乎快要灭绝了,如今只剩下了三只,人们正在努力采取措施来培育犀牛.
解答 32.B 细节理解题,根据第二段Workers hoped they would have a better chance of survival in a more natural habitat.可知将犀牛送走是希望他们在自然的环境中生活的更好,故选B.
33.B 推理判断题,根据第一段There were only five northern white rhinos left一共有五只犀牛;第三段One of the rhinos at the conservancy died in October;Another died at a zoo in the US city of San Diego;十月有一只犀牛在保护区死亡,另一只死于美国的一个动物园,因此犀牛的数量下降到3只,故选B.
34.A 细节理解题,根据第四段Rhinos are killed because many people in Asia want the animals'horns (角).They believe the horns will help with medical problems.可知犀牛被杀是因为在亚洲很多人想要犀角,他们认为这个角会帮助医疗问题,因此人们猎杀犀牛是想得到犀牛角用于医疗用途,故选A.
35.A 推理判断题,根据最后一段If cross-breeding is successful,there is hope that some part of the northern white rhino species may still live on.如果交叉育种成功,一部分的北白犀牛物种有希望还活着,最后一段介绍了三种培育犀牛的方法,所以从最后一段可知将来将采取其他措施培育犀牛,故选A.
