英语考研阅读真题

“I've never met a human worth cloning,” says cloning expert Mark Westhusin from the cramped confines of his lab at Texas A&M University. “It's a stupid endeavor.” That's an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two calves and expect to clone a cat soon. They just might succeed in cloning Missy later this year—or perhaps not for another five years. It seems the reproductive system of man's best friend is one of the mysteries of modern science.

Westhusin's experience with cloning animals leaves him vexed by all this talk of human cloning. In three years of work on the Missyplicity project, using hundreds upon hundreds of canine eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted fetuses may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.

Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin's phone at A&M College of Veterinary Medicine has been ringing busily. Cost is no obstacle for customers like Missy's mysterious owner, who wishes to remain unknown to protect his privacy. He's plopped down $3.7 million so far to fund the research because he wants a twin to carry on Missy?s fine qualities after she dies. But he knows her clone may not have her temperament. In a statement of purpose, Missy's owner and the A&M team say they are “both looking forward to studying the ways that her clone differs from Missy.”

The fate of the dog samples will depend on Westhusin's work. He knows that even if he gets a dog viably pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems. “Why would you ever want to clone humans,” Westhusin asks, “when we?re not even close to getting it worked out in animals yet?” [397 words]

长难句分析

1. That's an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy.

该句主干是That's an interesting choice of adjective。现在分词短语coming from... 做后置定语，修饰前面的名词choice，相当于一个定语从句(which is)coming from... ;在分词短语中，定语从句who... 也做后置定语，修饰先行词a man。

2. He knows that even if he gets a dog viably pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems.

该句主干是He knows that... 。that引导的宾语从句是一个主从复合句，且从句位于主句之前，主句是the offspring will face the problems... ;从句是让步状语从句：even if he gets a dog viably pregnant;should they survive是个省略了if的条件状语从句，为插入语，修饰主句。另外，主句的宾语the problems后接有过去分词短语shown... 做后置定语，相当于一个定义从句(that)are shown... ;冒号后的名词短语做the problems的同位语。

语篇分析

本文题材涉及生物技术。作者从克隆动物这个角度间接论证克隆人的不可行性，主张应该慎重对待克隆人研究。它是一篇观点论证型文章，按照“提出观点—论证观点—重申观点”的脉络展开论述，可分成三部分。

第一段为第一部分，提出观点：克隆人是不可行的。

引用专家Mark Westhusin和一位试图克隆其爱犬的富人的话(never met a human worth cloning，a stupid endeavor)表达作者的观点。接着介绍Mark Westhusin所进行的克隆动物的实验(two calves，a cat and a dog)，并特别指出对狗的克隆最具难度(one of the mysteries of modern science)。

第二、三段为第二部分，论证观点。

第二段：指出Mark Westhusin克隆动物的经验使他极力反对克隆人(vexed by talking of human cloning)。首句是段落主题句。段中详细介绍了一个克隆狗的项目(the Missyplicity project)中出现的状况：①从成百上千的卵中只获得一打左右基因匹配的胚胎;②转移到母体时没有一个胚胎存活下来。从这些细节中可以推出，克隆是低效而且危险的。这在末句“Cloning is incredibly inefficient, and also dangerous”得到了证实。该段最后还给出了Mark Westhusin的观点：动物实验中的浪费现象在人的研究中不能被接受。因此，该段将Mark Westhusin反对克隆人的态度表露无疑。

Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all. Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to look forward to. But such gloominess is misplaced. The fossil record shows that many species have endured for millions of years —— so why shouldn't we? Take a broader look at our species' place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years. Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline." So what does our deep future hold? A growing number of researchers and organizations are now thinking seriously about that question. For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence. Perhaps willfully, it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That's one reason why we have launched Arc, a new publication dedicated to the near future. But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves. This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come. 考研英语阅读翻译 几十年前，我们对于未来的看法尽管并不一致，但总的来说颇为乐观。我们相信科学和技术将会治愈人类的一切疾病，使所有人都过上充满机会和成就感的生活。 如今，随着我们对自己所面临的一系列威胁有了更深刻的认识，比如从小行星撞击，到流感，再到气候变化，乌托邦式已经不合时宜。你甚至可能会禁不住要想：人类几乎前途渺茫。 然而，这种担忧不合时宜。化石记录表明，许多物种已经存活了数百万年之久，那么人类为何就不可以呢?从一个更宏观的视角来看一看人类在宇宙中的地位，就会清楚明白，即使人类生存不了几十万年，至少再存活几万年的机会还是很大。在国际自然保护联盟的濒危物种 "红色名录"上查阅"智人"这一条目，你会读到："由于该物种分布非常广泛，适应性强，目前数量持续上升，且不存在导致其整体数量下降的重大威胁，故被列为最无危物种"。 那么，我们的遥远未来会是什么景象呢?越来越多的研究者和组织机构正在认真思考这个问题。比如，今日不朽基金会的旗舰项目是一台机械时钟，该时钟的设计目标是能够在几千几万年后保持计时功能。 这样做或许有些一意孤行，但推想久远的未来要比思考即将发生的未来更为容易。当今技术的可能发展及它的社会影响结果非常复杂，或许最好的办法是让科幻小说家和未来学家去探索我们能想象到的种种可能。这正是我们发行《弧》的原因之一，该新刊物旨在探索不远的未来。 但是，如果采用一个更为长远的视角，我们便能对惊人数量的事情做出很有把握的预测。通常，过去掌握着通向未来的钥匙：目前，我们已经充分了解有关地球历史和人类历史的长期发展模式，这使我们能对子孙后代的生存环境做出有根据的预测。 这种长远的视角使我们对未来的悲观态度更像是一股短暂的风潮。诚然，未来绝非一片光明。不过，我们已经有足够的知识去降低许多曾经威胁前人生存的危险，以及去改善后人的命运。 考研英语阅读词语解析 dedicated['dedi.keitid]adj. 专注的，献身的，专用的 overall[əuvə'rɔ:l]adj. 全部的，全体的，一切在内的 strike[straik]n. 罢工，打击，殴打 v. 打，撞，罢工，划 adaptable[ə'dæptəbl]adj. 能适应的，适应性强的，可改编的 planet['plænit]n. 行星 immediate[i'mi:djət]adj. 立即的，即刻的，直接的，最接近的 pessimistic[.pesi'mistik]adj. 悲观的，悲观主义的 population[.pɔpju'leiʃən]n. 人口 ，(全体)居民，人数 opportunity[.ɔpə'tju:niti]n. 机会，时机 evolution[.i:və'lu:ʃən]n. 进化，发展，演变 猜你喜欢： 1. 考研英语阅读美文双语 2. 考研英语历年阅读真题及答案 3. 考研英语阅读精华美文 4. 高中英语美文带翻译阅读范文欣赏 5. 考研英语阅读篇章的技巧 6. 简单英语阅读短文带翻译
