Passage 1With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That's a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a project called “Noah's Ark.”Dr. Duane Kraemer, a professor in Texas A&M's College of Veterinary Medicine a nd a pioneer in embryo(胚胎) transfer work and related procedures, says he salut es the Chinese effort and “I wish them all the best success possible. It's a wo rthwhile project, certainly not an easy one, and it's very much like what we're attempting here at Texas A&M—to save animals from extinction.”Noah's Ark is aimed at collecting eggs, embryos, semen(精子) and DNA of endang ered animals and storing them in liquid nitrogen. If certain species should beco me extinct, Kraemer says there would be enough of the basic building blocks to r eintroduce the species in the future.It is estimated that as many as 2,000 species of mammals, birds and reptiles w i l l become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.This week, Chinese scientists said they grew an embryo by introducing cells fr om a dead female panda into the egg cells of a Japanese white rabbit. They are n ow trying to implant the embryo into a host animal.The entire procedure could take from three to five years to complete.“The nuclear transfer of one species to another is not easy, and the lack of available panda egg s could be a major problem,” Kraemer believes. “They will p robably have to do several hundred transfers to result in one pregnancy. It take s a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth t he effort,” adds Kraemer, who is one of the leaders of the Missyplicity Project at Texas A&M, the first ever attempt at cloning a dog.“They are trying to do something that's never been done, and this is very sim ilar to our work in Noah's Ark. We're both trying to save animals that face exti nction. I certainly applaud their effort and there's a lot we can learn from wha t they are attempting to do. It'sa research that is very much needed.”61.

【参考译文】如果某些物种灭绝了，Kraemer说这将会有足够的基础建设材料再造这些物种。

答案精解提纲挈领本文为新闻报导类文章。

第一段为全文导语。

从第二段起具体介绍Duane Kraemer对中国科学家克隆大熊猫的做法的评价，并与美国科学家正在从事的“诺亚方舟”计划做了对比。

文章最后一段表达了他们对中国同行所做的工作的高度评价，由此也向读者介绍了中国科学家在克隆大熊猫这个项目上所做的努力。

61. C)。

细节题。

题意是：“诺亚方舟”项目的目的是什么。

迷途点津 A)把胚胎植入受体动物体内；B)赞扬中国连拯救大熊猫上付出的努力；C) 拯救濒危动物使其不敢于灭绝；D)把死去的雌性熊猫的细胞导入一只日本白鬼的卵细胞中。

第三段第一、二句指出，“诺亚方舟”项目的目的在于收集濒临灭绝的动物的卵子、胚胎、精子和DNA，并且液体氮将它们储存起来。

万一某些物种灭绝了，将会有足够的基础建设材料再造这些物种。

第一段的第一、二句也说，中国正努力克隆大熊猫以拯救这些濒危动物。

而这与“诺亚方舟”是类似的。

最后一段第二句又一次提到了这个项目的目的，即拯救濒临灭绝的物种。

62. B)。

细节题。

题意是：根据文章，中国的克隆大熊猫项目要用多长时间。

迷途点津 A)一年；B)三至五年；C)两年；D)二十五年。

第六段指出，整个程序需要三至五年完成。

本句中的procedure指的就是克隆大熊猫的过程。

63. B)。

词义题。

题意是：第七段里的groundbreaking可解释为什么意义。

迷途点津 A)全新的；B)开创性的；C)进化的；D)划时代的。

break ground原意为“ 破土；创建”。

groundbreaking所在句子的意义为：这需要很长时间，而且难度很大，但是一旦成功，便会成为开创性的科学。

64. A)。

细节题。

题意是：根据Kraemer教授的观点，克隆大熊猫的主要问题是什么。

迷途点津 A)缺少可得到的熊猫卵子；B)缺少受体动物；C)缺少合格的科研人员；D) 缺少资金。

由第七段第一句可知，将一个物种的细胞核移植到另外一个物种是件不容易的事，缺少大熊猫的卵子可能会成为一个重要问题。
