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 (保護(hù)區(qū)) 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.
32.Why were the three northern white rhinos brought to the conservancy in Kenya?B
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 本文考察環(huán)境保護(hù)類短文閱讀,主要向我們講述了北部白犀牛由于人們的掠殺現(xiàn)在幾乎快要滅絕了,如今只剩下了三只,人們正在努力采取措施來培育犀牛.
解答 32.B 細(xì)節(jié)理解題,根據(jù)第二段Workers hoped they would have a better chance of survival in a more natural habitat.可知將犀牛送走是希望他們在自然的環(huán)境中生活的更好,故選B.
33.B 推理判斷題,根據(jù)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護(hù)區(qū)死亡,另一只死于美國的一個動物園,因此犀牛的數(shù)量下降到3只,故選B.
34.A 細(xì)節(jié)理解題,根據(jù)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.可知犀牛被殺是因?yàn)樵趤喼藓芏嗳讼胍,他們認(rèn)為這個角會幫助醫(yī)療問題,因此人們獵殺犀牛是想得到犀牛角用于醫(yī)療用途,故選A.
35.A 推理判斷題,根據(jù)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.如果交叉育種成功,一部分的北白犀牛物種有希望還活著,最后一段介紹了三種培育犀牛的方法,所以從最后一段可知將來將采取其他措施培育犀牛,故選A.
點(diǎn)評 考查學(xué)生的細(xì)節(jié)理解和推理判斷能力.做細(xì)節(jié)理解題時一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確選擇.在做推理判斷題時不要以個人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.
