US.More than 62,000 people in the US.alone are waiting to _1_ donated hearts，lungs and so on.The number of human donors falls far short of _2_.Pig organs are of a（n）_3_ size to human organs，and some scientists hope they might be used to help meet the _4_.But previous attempts to transplant pig tissue into humans have _5_.The five pigs _6_ a gene that adds a sugar to the surface of pig cells.The sugar would _7_ immune（免疫的）rejection of the tissue.“This advance provides a neartime _8_ for overcoming the problem that there is not enough human organs for transplants，”says an expert.“This is the _9_ gene for overcoming the _10_ stage of rejection.”_11_，scientists warn that much more work is necessary _12_ organs from copies of the pigs could be transplanted into humans.Human genes will need to be added，to _13_ rejection of the organ in the long term.There are also _14_ that pig viruses could infect patients.Cloning techniques were _15_ to the production of the pigs.Genes can only be knocked out（去除）in a single cell.Cloning of these single cells then allowed the _16_ of a whole animal in which the gene was knocked out in every cell.But the PPL researchers have _17_ in knocking out only one copy of the gene.The team will now attempt to knock out both copies of the gene.The team will also _18_ tests to investigate whether a virus from the pigs could infect human cells.“Although a lot of the work is very _19_，were still very far off being able to grow an organ，” says Julia，who is working on this project and quite _20_ to creating similar knockout pigs with researchers at the University of Missouri.1AexchangeBcheckCpossess Dreceive2Adiscussion BdemandCdoubt Ddistance3Abeneficial BidenticalCsimilar Dcertain4Ashortage BconditionCsatisfaction Dargument5Acontinued

animals have been cloned?Scientists have 1._ cloning animals for many years.In 1952，the first animal，a tadpole（蝌蚪），was cloned.2._ the creation of Dolly，the first mammal（哺乳动物）cloned from the cell of an adult animal，clones were created 3._embryonic（胚胎的）cells.Since Dolly，researchers have cloned a number of large and small animals 4._（include）sheep，goats，cows，mice，pigs，cats，rabbits，and a gaur（野牛）All these clones were created using nuclear transfer technology.Hundreds 5._ cloned animals exit today，but 6._ number of different species is limited.Attempts 7._ cloning certain species such as monkeys，chickens，horses，and dogs，have been unsuccessful.Some species may be 8._ resistant to somatic（躯体的）cell nuclear transfer than others.The process of stripping（剥离）the nucleus from an egg cell and replacing it 9._ the nucleus of a donor（供体）cell is traumatic（创伤的）one，and improvements in cloning technologies may be needed before many species can be cloned 10._（success）参考答案一、 1答案：compulsory2答案：regulations 3答案：assumption 4答案：flour 5答案：bothered二、 1答案：thatwhich2答案：whetherwhat3答案：whathow4答案：WhyWhat5答案：whatthat6答案：whetherthat7答案：howwhat三、 1答案：The fact disappoints us that our basketball team is defeated.2答案：They are having an argument whether we can clone human beings.3答案：Every one should have the belief that nature should never be destroyed.4答案：She has made a promise that she will make experiments on cloning a monkey.四、 1答案：that all his hard work had finally paid off2答案：such as maths and physics3答案：whether we should continue to do the experiment4答案：The story goes that5答案：that smoking should be forbidden in public places6答案：that the school library provide more books五、 1答案：D解析：由本段内容可知，应是等待接受器官的移植。2答案：B解析：器官捐献不能满足人们的需求，demand符合语境。3答案：C解析：根据上下文可知，克隆猪的器官可以被移植到人体内，它们的器官应该和人类的器官大小相似。4答案：A解析：根据本段第二句“The number of human donors falls far short of _.”可知，克隆猪的器官是为了弥补人类可移植器官的不足。5答案：B解析：上一句提到科学家期望克隆猪的器官能够应用于人类器官移植领域，“But”表示转折，说明以前类似的试验失败了。6答案：A解析：由下文“.a gene that adds a sugar to the surface of pig cells.The sugar would _ immune（免疫的）rejection of the tissue.”可推测，这一基因会导致不好的结 果，又根据“This advance provides.”可知，这五只克隆猪没有这一基因，因此选lack。7答案：B解析：根据上下文可知，这种糖分可能会使器官产生免疫排斥，cause符合语境。8答案：D解析：根据后面“overcoming the problem”的提示可知，这一进步对人类可移植器官不足的问题提供了一个解决办法。9答案：C解析：根据上文“.a gene that adds a sugar to the surface of pig cells.”可知，这一基因对克服器官排斥问题很关键，所以选key。10答案：D解析：根据下一段第二句“Human genes will need to be added，to _ rejection of the organ in the long term.”可知，对这一基因的处理只能解决器官排斥早期的一些问题。11答案：A解析：根据下文“.scientists warn that much more work is necessary.”可知，本段内容与上一段意思是转折
