　　2015年北京人大附中小升初分班考試真題：英語

　　With only about 1， 000 pandasleft in the world， China is desperately trying to clone(克隆)the animal and save the endangered species(物種). That’s amove similar to what 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 ofendangered animals and storing them in liquid nitrogen. If certain speciesshould become extinct， Dr. Duane 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 over100 years. The panda， native 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 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(having 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 adog.

　　“They are trying to dosomething that’s never been done， and this is very similar to our work inNoah’s Ark. We’re both tryin

　　ng 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’s a research that is very much needed.”

　　1.The aim of “Noah’s Ark” project is to _______.

　　A. make efforts to clonethe endangered pandas

　　B. save endangeredanimals from dying out

　　C. collect DNA ofendangered animals to study

　　D. transfer the nuclearof one animal to another

　　2.According to Professor Kraemer， the major problem in cloning pandas would bethe lack of _____.

　　A. available pandaeggs B. host animals

　　C. qualifiedresearchers D. enough money

　　3.The best title for the passage may be _______.

　　A. China’s Success inPandas Cloning

　　B. The First ClonedPanda in the World

　　C. Exploring the Possibilityto Clone Pandas

　　D. China —the NativePlace of Pandas Forever

　　4.From the passage we know that _______.

　　A. Kraemer and his teamhave succeeded in cloning a dog

　　B. scientists try toimplant a panda’s egg into a rabbit

　　C. Kraemer will workwith Chinese scientists in clone researches

　　D. about two thousand ofspecies will probably die out in a century

　　【解析】

　　本文講述中國(guó)正在竭力克隆瀕臨絕種的熊貓，這和Texas A & MUniversity 的Noah‘s Ark(諾亞方舟)工程極為相似，都是想拯救瀕臨滅絕的動(dòng)物。

　　1. B。語義理解題。從第2段內(nèi)容可知，“諾亞方舟”工程的目標(biāo)是把瀕臨滅絕的動(dòng)物的蛋(卵)、胚胎、精液和DNA儲(chǔ)存在液體氮中，如果某一種動(dòng)物瀕臨滅絕時(shí)，將來可以重現(xiàn)這一動(dòng)物。

　　2. A。細(xì)節(jié)題。從第6段第1句話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 可以做出正確判斷。

　　3. C。主旨題。從文章內(nèi)容來看，無論是中國(guó)還是世界克隆熊貓還沒有成功，所以排除A、B項(xiàng);D項(xiàng)內(nèi)容明顯與文章內(nèi)容不符，故排除。所以“探索克隆熊貓的可能性”應(yīng)該是這篇文章的標(biāo)題。

　　4. D。判斷題。此題B項(xiàng)的干擾性較強(qiáng)，但由于它沒有說明是Chinesescientists，所以應(yīng)排除。A、C項(xiàng)明顯與原文不符。根據(jù)文章第3段第1句可知答案非D莫屬。
