2、hat a Texas A M University researchers have beenundertaking for the past five years in a project called Noah’s Ark.Noah’s Ark is aimed atcollecting eggs, embryos （胚胎）， semen and DNA of endangered animals and storing themin liquid nitrogen. If certainspeciesshould become extinct, Dr. Duan

3、e Kraemer, a professor in Texas A M’sCollege of Veterinary Medicine , says there would be enough of the basicbuilding blocks to reintroduce the species in the future.It is estimated that asmany as 2, 000 species of mammals, birds reptiles will become extinct in overlOO years. The panda, native

4、 only to China, is in danger of becoming extinct inthe next 25 years.Thisweek, Chinese scientists said they grew an embryo by introducing cells from adead female panda into the egg cells of a Japanese white rabbit. They are nowtrying to implant the embryo into a host animal.The entire procedurecould

5、 take from three to five years to complete.The nuclear transfer (核子移植)of one species to another is not easy , and the lack of available (capable ofbeing used) panda eggs could be a major problem, Kraemer believes. They willprobably have to do several hundred transfers to result in one pregnancy (hav

6、ing a baby). It takes a long time and it’ s difficult, but this could begroundbreaking science if it works. They are certainly not putting any livepandas at risk, so it is worth the effort, adds Kraemer, who is one of theleaders of the Project at Texas A M, the first-ever attempt at cloning ad

7、og.They are trying to dosomething that’snever been done, and this is very similar to our work inNoah’s Ark. We’re both tryinng to save animals that face extinction. I certainlyappreciate their effort and there’s a lot we can learn from what they areattempting to do. It’

11、 a century【解析】本文讲解并描述中国正在竭力克隆面临绝种的熊 猫，这和 Texas A MUniversity 的 Noahs Ark（诺亚方舟） 工程极为相像，都是想挽救面临灭亡的动物。1. Bo语义理解题。从第2段内容可知，诺亚方舟 工程的目标是把面临灭亡的动物的蛋（卵）、胚胎、精液和DNA 储存在液体氮中，假如某一种动物面临灭亡时，将来可以重 现这一动物。2. Ao细微环节题。从第6段第1句话The nuclear transfer （核子移植）of one species toanother is not easy, and the lack of available （capable of being used ） pandaeggs could be a major problem 可以做出正确推断。3. Co主旨题。从文章内容来看，无论是中国还是 世界克隆熊猫还没有胜利，所以解除A、B项;D项内容明显 与文章内容不符，故解除。所以探究克隆熊猫的可能性应当 是这篇文章的标题。4. Do推断题。此题B项的干扰性较强，但由于它 没有说明是Chinesescientists,所以应解除。A、C项明显 与原文不符。依据文章第3段第1句可知答案非D莫属。2
