Question

【題目】閱讀下列短文，從每題所給的四個選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。

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 2009 from 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 41 years 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.

A. they wanted to get rhinos’ horns for medical use

【解析】

試題分析：本文講的是北部白犀牛由于人們的掠殺幾乎快滅絕了，現(xiàn)如今只有3只，人們正努力采取措施來培育犀牛。

【1】B細(xì)節(jié)理解題。根據(jù)The three rhinos were brought to the conservancy in 2009 from a zoo in the Czech Republic. Workers hoped they would have a better chance of survival in a more natural habitat. 三只犀牛在2009年從捷克動物園被帶到保護(hù)區(qū)。工人們希望他們在更自然的環(huán)境中有更好的生存機(jī)會�？芍�被帶到肯尼亞是為了保證他們在自然環(huán)境中生活得更好。故選B

【2】B細(xì)節(jié)理解題。根據(jù)There were only five northern white rhinos left. 北部白犀牛只有五只 和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。另一個死于在美國市的一個動物園�？赏茢嘞�牛數(shù)量下降到3只。故選B

【3】A細(xì)節(jié)理解題。Rhinos are killed because many people in Asia want the animals’ horns (角). They believe the horns will help with medical problems. 犀牛被掠殺是因?yàn)樵趤喼藓芏嗳讼胍�犀角。他們認(rèn)為這個角會幫助醫(yī)療問題�？芍�人們獵殺犀牛因?yàn)樗麄兿氲玫较�牛角用于醫(yī)療用途。故選A

【4】A推理判斷題。If cross-breeding is successful, there is hope that some part of t he northern white rhino species may still live on. 如果交叉育種是成功的，一些部分的北白犀牛物種有希望還活著。最后一段介紹了3種培育犀牛的方法，所以從最后一段我們可以得知將采取其他措施培育犀牛。故選A
