逻辑是四级阅读解题的关键吗(阅读理解逻辑推理)

Passage 1

With 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 ill 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 eggs 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's a research that is very much needed.”
