杨鹏难句130句 杨鹏难句130句 1. that sex ratio will be favored which maximizes the number of　descendants an individual will have and　hence the number of gene copies　transmitted. （难度系数5，下同） 译文：那种性别比例能在最大程度上增加一个个体所能拥有的后代数量，并因此能在最大程度上增加所传递到后代身上去的基因复制品的数量。 难句类型：倒装、省略 a本句的正常语序应当是：that sex ratio which maximizes the number of descendnts an individuall will have and hence the number of gene copies transmited will be favored.但是因为主语that sex　ratio之后的以which引导的修饰它的定语从句，如果按照以上语序，则有头重脚轻之感。所以原文将此长长的从句倒装成谓语will be favored之后。 b在which引导的从句中，有两处省略：第一处在maximize的第一个宾语the number of descendants that an individuall will have中，　an individuall will have是修饰descendants的定语从句，但是，因为descendants在从句中作have的宾语，所以引导词that可以省略。第二处省略是在第二个the number of 之前，省略了与前面一样的成分that sex ratio which maximizes. and hence在此表示后面的成分作为前面“最大化一个个体的后代的数目的”结果。 意群训练：that sex ratio will be favored which maximizes the number of　descendants an individual will have and　hence the number of gene copies　transmitted. 2. （this is ）a desire to throw over reality a light that never was might give away abruptly to the desire on the part of what we might consider a novelist-scientist to record exactly and concretely the structure and texture of a flower .(5++)复杂+倒装+省略; （这是一种）照亮现实的欲望，此欲望从来就不会唐突的取代后面的那种欲望，后者是我们可以将其部分的理解为一个兼任小说加和科学家的人想要去准确并具体的下一朵花的结构和文理的那种意义上的欲望。 解释：本句子的难度在一切gre、gmat包括lsat考试中所出现的难句中堪称登峰造极，可以确定地讲，类似此句子的难度的语言，在计算机考试的现场绝无可能出现。如果对此句话不感兴趣，可以把其废掉不读。 a、 这句话读起来别扭的第一个原因，是因为它根本就不是一个句子。句首省略了this is 。这种用一个词代替一个句子的方式如果在书面语中出现，只能出现在高级英语中，因此我们以前的英语学习中从未遇到过。其形式类似于我们中文的“精彩”是“这句话真是精彩”的省略形式。 b、 desire后跟着两个大的修饰成分，一个是to throw over reality a light，其中的a light 是被倒装到了over reality之后，正常应是throw a light over reality.不过这个便装部分与throw距离不远，读者看得还算懂。关键是第二个修饰成分。注意：从that开始直到句尾结束的长长的定语从句不是修饰其前的light的，而是修饰一开始的desire的。 c、 第二个修饰成分中又来了一个倒装，由于作者为了强调never,所以将其提前，引发了定语从句中的倒装：正常语序应该是that might never be given away，倒装后系动词was被提前，given因为在情态动词might之后所以变成了原型give。a give way to b，是a让位于b，而a be given way to b，　则是a取代b。on the part of 之后的部分修饰后面的desire，what引导的从句现场阅读时可以看成一个名词。what从句中的不定式to recored exactly and concretely the structure and texture of a flower中又有一个避免头重脚轻的倒装，正常语序应该是to recored the structure and texture of a flower exactly and concretely。 d、 就算能够看懂这句话的结构，可能仍然理解不了意思。本句的意思是，哈代(注：人名老的冲动是一种简单的、说明现实的欲望，新冲动是一种即是小说家又像科学家的仔细研究一个东西的特点那样的欲望（新冲动），前一种欲望是永远也不能取代后者的。 意群训练：（this is ）a desire to throw over reality a light that never was might give away abruptly to the desire on the part of what we might consider a novelist-scientist to record exactly and concretely the structure and texture of a flower . 3. hardy’s weakness derived from his apparent inability to control the comings and goings of these divergent impulses and from his unwillingness to cultivate and sustain the energetic and　risky ones. （3） 难句类型：复杂修饰、省略、抽象词 译文：哈代的缺陷一方面缘起于他的某种明显的无能，无法控制好那结不尽相同的创作冲动的穿梭往来；另一方面缘起于他不愿意去培养和维持那些富于生机活力和风险性强的创作冲动。 解释：介词from的宾语有两个并列的部分，由and所连接，在and之后的第二个from前，省略了前面一样的谓语动词derive。本句之所以难，有两个原因，一是derived from 后面的成分太长，初学者难以一下子看下来；二是作为一篇文科文章，用词抽象，难以迅速理解。 意群训练：hardy's weakenss derived from his apparent inability to control the comings and goings of these divergent impulses and from his unwillingness to cultivate and sustain the energyetic and risky ones. 4. virginia woolf’s provocative statement about her intentions in writing mrs. dalloway has regularly been　ignored by the critics，since it highlights an aspect of her literary interests very different from the traditional picture of the "poetic" novelist concerned with examining states of reverie and vision and with following the intricate pathways of individual consciousness. （5） 难句类型：复杂修饰、省略、抽象词 译文：弗吉尼亚.伍尔夫（virginia woolf）在创作《黛洛维夫人》（mrs. dalloway）时有关其创作意图的这番发人深思的陈述，迄今为止一贯为文学评论家们所忽略，因为它突出反映了她诸多文学兴趣中某一方面，而这一方面则与人们对“诗性”小说家（poetic novelist）所形成的传统见解大相径庭。所谓的“诗性”小说家，所关注的是审视想入非非和白日梦幻的诸般状态，并致力于追寻个体意识的通幽曲径。 解释：本句逗号以前只有复杂修饰的长主语有些难，但总的来讲比较好懂，since引导的原因状语从句较难。 a、 since之后的it指前面的statement，highlight的宾语an aspect之后有两个修饰成分，一个是of her literary interests，　另一个是以that引导的定语从句that is very different from the traditional picture of the poetic novelist，都是修饰an aspect的。novelist后面又有由and 连接的两个介词结构concerned with doing 修饰novelist. b、 句中有两处省略，一是在her literary interests that is very different from当中，修饰interests的定语从句中引导词＋be that is 一起省略了。第二处在and之后，由于concerned with与前面的concerned with重复，所以concerned被省略。 c、 本句另外一个难懂的地方，就是使用了大量的抽象词。这是文学市评论题材的文章的一个特点。 virginia woolf’s provocative statement about her intentions in writing mrs. dalloway has regularly been　ignored by the critics，since it highlights an aspect of her literary interests very different from the traditional picture of the "poetic" novelist concerned with examining states　　of reverie and vision and with following the intricate pathways of individual consciousness. 5. as she put it in the common reader , “it is safe to say that not a single law has been framed or one stone set upon another because of anything chaucer said or wrote ; and yet , as we read him , we are absorbing morality at every pore .”（5-） 抽象词、抽象词组、比喻 就像她在《致普通读者》一书中所表达的那样，“尽管可以毫无疑问的说，没有任何法律被指定出来，也没有任何高楼大厦被建立起来是因为乔叟说了什么或者写了什么；然而，当我们读它的书的时候，我们身上每一个毛孔都充满了道德” 这句话不但用了词抽象，还用了比喻的修辞手法。是指没有因为乔叟的言论而产生任何实际的行为规则或政治机构，但我们受其影响之深，以及其影响力之大。 as she put it in the common reader , “it is safe to say that not a single law has been framed or one stone set upon another because of anything chaucer said or wrote ; and yet , as we read him , we are absorbing morality at every pore .” 6. with the conclusion of a burst activity , the lactic acid level is high in the body fluids , leaving the large animal vulnerable to attack until the acid is reconverted , via oxidative metabolism , by the liver into glucose , which is then sent (in part )back to the muscles for glycogen resynthesis .（4+） 难句类型：复杂修饰、插入语、专有名词 译文：随着爆发出来的运动的结束，再体液中乳酸含量会变得很高，使得大型动物处于容易受到攻击的状态，直到乳酸通过有氧新陈代谢，被肝脏转化成（convert into）葡萄糖，而葡萄糖接下来又会（部分）传送回肌肉中重新合成糖原 。 解释：本句中修饰成分极多，以分词修饰和介词结构修饰为主，作各种类型的状语。前面的状语和主句还好理解，从leaving开始句子变难；leaving引导的直到句末的结构来做整个句子的状语；分词中又包含了三个状语，其中的两个via oxidative metabolism by the liver又起到了插入语的作用，把be converted into拆成两段。 本句的另外一个特征是其中充斥着专有名词。其中的body fluids, oxidative和resynthesis通过字面的意思或者根据词头、词根我们还是应该猜出其意思的，lactic acid, metabolism和muscle这三个词在生物类文章中极其常用，大家应该背下来；而glycogen这种东西则没，只能作一个首字母提炼。但是请记住，gre和gmat文章中只要出现了这种专有名词，出题者是一定会在文章中把它在文章中所乃至的词义解释清楚的，所以读者遇到文章中做了解释的专有名词，应该力求把解释看懂。 意群训练：with the conclusion of a burst activity , the lactic acid level is high in the body fluids , leaving the large animal vulnerable to attack until the acid is reconverted , via oxidative metabolism , by the liver into glucose , which is then sent (in part )back to the muscles for glycogen resynthesis . 7. although gutman admits that forced separation by sale was frequent，he shows that the slaves’ preference，revealed most clearly on plantations where sale was infrequent，was very much for stable monogamy. （3+） 难句类型：插入语 译文：虽然古特曼承认，由于奴隶买卖而造成的被迫离散甚为频繁，但他还是证明，奴隶的偏爱——在那些奴隶买卖并不频繁的种植园上被最为显著地揭示出来——在很大程度上侧重于稳定的一夫一妻制（monogamy）。 解释：本句中插入语的使用revealed most clearly on plantations where sale wa infrequent, 后半个分句中的主语that slaves' preference与系动词was离得太远，造成阅读的困难。 意群训练：although gutman admits that forced separation by sale was frequent，he shows that the slaves’ preference，revealed most clearly on plantations where sale was infrequent，was very much for stable monogamy. 8. gutman argues convincingly that the stability of the black family encouraged　the transmission of-and so was crucial in sustaining-the black heritage of folklore，music，and religious expression from one generation to another，a heritage that slaves were continually fashioning out of their african and american experiences. （4） 难句类型：复杂修饰、插入语 译文：古特曼人令人信服地论辨道，黑人家庭的稳定有助于包括民间传说、音乐、及宗教表达在内的黑人文化遗产一代一代传递下去，因而在维持文化遗产方面也起着至关重要的作用，而对于这种文化遗产，黑奴们不断地从其非洲和美洲的经历中予以丰富发展。 解释：由that引导的宾语从句中，encouraged的宾语the transmission of the black heritage被同时表示并列和转折的and so 分开，给读者造成了阅读上和理解上的困难。最后一个逗号后面的部分是修饰前面的black heritage的同位语。 意群训练：gutman argues convincingly that the stability of the black family encouraged　the transmission of-and so was crucial in sustaining-the black heritage of folklore，music，and religious expression from one generation to another，a heritage that slaves were continually fashioning out of their african and american experiences. 9. this preference for exogamy，gutman suggests， may have derived from　west african rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin. （3+） 难句类型：复杂修饰、插入语 译文：古特曼表示，这种对于外部通婚的偏爱很有可能缘起于西部非洲制约着婚姻的规定，尽管这些规定在一个和另一个部落群体之间不尽相同，但都涉及到某种对近亲联姻（union with close kin）的禁止。 解释：本句有两个插入语，第一个插入语gutman suggests割裂了主句的主语和谓语。west african rules后跟着两个修饰成分，第一个是分词修饰(governing marriage), 第二个是以which引导的非限定性定语从句，从句中出现了第二个插入语though they differed from one tribal group to another，又割裂了从句引导词与谓语之间的联系。 意群训练：this preference for exogamy，gutman suggests， may have derived from　west african rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin. 10. his thesis works relatively well when applied to discrimination against blacks in the united states，but his definition of racial prejudice as "racially-based negative prejudgments against a group generally accepted as a race in any given region of ethnic competition，" can be interpreted as also including hostility toward such ethnic groups as the chinese in california and the jews　in medieval europe. （4+） 难句类型：复杂修饰、插入语、抽象词 译文：该社会学家的命题当被应用于针对美国黑人的歧视时，相对而言尚能适用，但他对种族偏见所下的定义——即“以种族为基础的、针对某个群体的消级的先入之见，而该群体在任何特定的种族竞争地区则被普遍认作一种族”——可被理解成同样也襄括了针对加利福尼亚州的中国人以及中世纪的犹太人这样一些种族群体的敌视态度。 解释：本句长度惊人，插入部分比较长，再加上不乏抽象词，所以较为难懂，在表示转折的后半个分钟中，长长的插入语as raciallybased negative prejudgments against a group generally accepted as a race in any given region of thnic competition作为主语his definition of racial prejudice的同位语，使分句中的主谓相隔千山万水。除此之外，本句用词抽象，语义难以理解，对读者的词汇功底较高。考试现场如无法读懂，宜用合理化原则中的取非读法，but之前的分句说的是其论点对美国黑人的种族歧视是较为管用，转折后的内容就应该说其理论对华人和犹太人相对无用。 意群训练：his thesis works relatively well when applied to discrimination against blacks in the united states，but his definition of racial prejudice as "racially-based negative prejudgments against a group generally accepted as a race in any given region of ethnic competition，" can be interpreted as also including hostility toward such ethnic groups as the chinese in california and the jews　in medieval europe. 11. such variations in size， shape，chemistry， conduction speed， excitation threshold，and the like as had been demonstrated in nerve cells remained negligible in significance for any possible correlation with the manifold dimensions of mental experience.（5） 难免类型：复杂修饰 译文：类似于这些已经被在神经细胞中证明的在大小、形状、化学过程、产生的速度、兴奋阈值及其类似的方面上所发生变化，当他们被用来与大脑的体验以可能的方式联系起来的时候，他们在重要性上仍然是微不足道的。 解释：即使是初练难免的人其实也很熟悉such thing as something这样的语言方式，可是当中间的小东西thing居然变成了一个长达十二个单词的大东西的时候，实在令人搞不清后面的as及其后的something 到底为哪方神圣。再加上以such as 为中心的长主语距离系动词remain太远，更增加了本句的难度。请读者反复阅读，直到读出这样的感觉：顺序阅读原文时，原文似乎就是几大块，就好像是such things as a remain negligible in a certain sense. 意群训练：such variations in size, shape, chemistry, conduction speed, excitation threshold, and the like as had been deomnstrated in nerve cells remained negligible in significance for any possible correlation with the manifld dimensions of mental experience. 12. it was possible to demonstrate by other methods refined structural differences among neuron types ; however , proof was lacking that the quality of the impulse or its condition was influenced by these differences , which seemed instead to influence the developmental patterning of the neural circuits .(5) 有可能通过其他方法来证明神经元种类间的细微的结构差异；可是，这样的证据是缺乏的，即神经冲动的性质或者状态是受这些差异所影响的，而这些差异看起来却能影响神经网络的发育模式。 难免类型：复杂修饰、倒装 解释：与很多人的印象相反，lack从来就不能作形容词，它只有动词或名词的词性。其形容词的形式是lacking,意思是缺乏的、不足的。 本句的在however 之前和之后的两个分句，是两个倒装结构，前一个是小倒装，正常语序是：to demonstrate refined structural differences among neuron types by other methods: however后面是个大倒装，lacking之后的that引导的同位语人名是修饰主语proof的，但是因为它太长，所以为了避免头重脚轻，被放到lacking之后，正常的语序应该是proof that the quality of ..was lacking 意群训练：it was possible to demonstrate by other methods refined structural differences among neuron types; however, proof was lacking that the quality of the impulse or its condition was influenced by these differences, which seemed instead to influence the developmental patterning of the neural circuits. 13. although qualitative variance among nerve energies was never rigidly disproved，the doctrine was generally abandoned in favor of the opposing view，namely，that nerve impulses are essentially homogeneous in quality and are transmitted as "common currency" throughout the nervous system. （4） 尽管在神经能量上存在着质的不同，这一点从来都没有在严格的意义上被反对过，但是以上教条通常被抛弃掉，而转向相反的观点，即：神经冲动从根本上本质相同，而且被当作“一种普通流”在整个神经系统中传播。 难句类型：复杂修饰、双重否定 解释：前半个分句中有一个双重否定，was never rigidly disproved,这种表示法用中文说出来还是比较好懂的，原因是我们熟悉中文的这种表示法，但在英文中出现，因为在以前的学习中见得少，所以感觉上很别扭。因此，同学们的任务，就是通过反复阅读此类句子来熟悉这样的英语。其实在英文表达中，很多双重否定与中文表达是一样的，表示肯定；如not unlimited就等于limited。但是值得读者注意的是在gre和gmat这两种对考生的逻辑有苛刻要求的考试中，如果这种双重否定中所涉及的概念不是dichotomous(即二分法的词汇，比如上面例子中的limited和unlimited)，则双重否定不一定表示肯定；比如本例中的not disprove, 不能理解为agree， 不反对者中，的确有人会同意，但通常心存疑虑，随大流者居多。不但如此，大双重否定中加上限定词以后，在否定的范围上也有所变化，如本句的be never rigidly disproved，没有完全被反对，不能理解为从来都被严格支持的，而应该理解成从来都可能有人支持的。综上所述，对双重否定的句子，简单的把其置换为肯定，不是最精确的理解。而最好的办法，就是通过多读、多练来熟悉其语言表达及其逻辑方式，按照其字面的表达理解成没有完全否定，然后大脑中反应出其目前的生存状态是一个仍未消失的状态；这种理解才是在考试现场既快速又精确的理解。 运用前面所说的用合理化原则中的取非读法，可以很容易的读出作者在后半个分句中想说前面的那种观点被反对了。但是，初学者会对这个分句中的something be abandoned in favor of something else这种语言表达感到突然，如果理解成因为喜后者而抛弃了前者，虽然也能说得通，但是其实原文从来没有这种因果关系，in favor of强调的是这两种动作的同时性；抛弃了前者，而转向后者，namely之后的内容是前面的opposing view的同位语。 意群训练：although qualitative variance among nerve energies was never rigidly disproved, the doctrine was generallyabandoned in favor of the oppsing view, namely, that nerve impulses are essentially homogeneous in quality and are transmitted as "common currency" throught the nervous system 14. other experiments revealed slight variations in the size，number, arrangement，and interconnection of the nerve cells，but as far as psycho neural correlations were concerned，the obvious similarities of these sensory fields to each other seemed much more remarkable than any of the minute differences. （4 -） 尽管其他实验显示在神经细胞的大小、数量、排列和相互连接上有一些小的差异，但是就心理-神经的关系而言，这些感官区域彼此之间的明显的相似性看起来比起微小的差异更为令人注目。 难句类型：复杂修饰、插入语 解释：在前后两个分句之间有一个插入语as far as psychoneural correlations were concerned。在后面的分句中，主语the obvious similarities之后的、修饰主语的成分较长、以至于有很多读者看到相隔很远的more remarkable than时一下子反应不过来是什么比后者更明显。其简化形式应为：similarities seemed more remarkable than differences。 意群训练：other experiments revealed slight variations in the size, number, arrangement, and interconnection of the nerve cells, but as far as psychoneural correlations were concerned, the obvious similarities of these sensory fileds to each other seemed much more remarkable than any of the minute differences. 15. although some experiments show that，as an object becomes familiar，its internal representation becomes more holistic and the recognition process correspondingly more parallel，the weight of evidence seems to support the serial hypothesis, at least for objects that are not notably simple and familiar. （4+） 虽然某些实验表明，随着一个物体变得熟悉起来，其内心再现图像亦更具整体感，辨认过程相应地更趋于平行，但证据的砝码似乎在支持序列假设（serial hypothesis），至少是对于那些不甚简单、不甚熟悉的物体来说。 难句类型：复杂修饰、插入语、省略 解释：在although引导的分句中，谓语shows后面跟着一个长长的宾语从句，从句中先出现一个插入语as an object becomes familiar,之后的内容是由and 连接的两套并列的主谓宾。其实and前后就是两个句子，只不过作者省略了后面的句子中与前面相同的引导词that和谓语become。 句子中有一个生词holistic，其实即使不认识，也能用合理化原则猜出它是后面serial的反义词、parallel的同义词，大约是统一、完整或同时的意思；其实只要能理解到其是与serial相反的意思即可。 意群训练：although some experiments show that，as an object becomes familiar，its internal　representation becomes more holistic and　the recognition process correspondingly more parallel，the weight of evidence　seems to support the serial hypothesis，　　at least for objects that are not notably simple and familiar. 16. in large part as a consequence of　the feminist movement，historians have focused a great deal of attention in recent years on determining more accurately the status of women in　various periods. （3+） 在很大程度上，由于女权主义运动（feminist movement）的缘故，史学家近年来汇聚了大量的注意力，来更为准确地确定妇女在各个历史时期的地位。 focus a on b; 难句类型：倒装 解释：focus a on b指把a集中于b，本句中介词on的宾语determining/more accurately the status of women invarious periods中有一个小倒装，正常语序应该是determining the status of women in various periods more accurately。 意群训练：in large part as a consequence of the feminist movement, historians have focused a great deal of attention in recent years on determining more accurately the status of women in various periods. 17. if one begins by examining why ancients refer to amazons , it becomes clear that ancient greek descriptions of such societies were meant not so much to represent observed historical fact 每real amazonian societies 每 but rather to offer ※moral lessons§ on the supposed outcome of women＊s rule in their own society . (4) 如别我蝇珂旃噶一下为什系嘉人颇提善亚镇逊人ㄛ下面腔一萸憩曹腕清晰剩ㄛ饶憩是嘉希帮勤衾这笱扦颇腔镗睡祥是太嗣腔掩用懂桶湛夤舷腔荡史岈妗＂＂凌正腔亚镇逊扦颇腔＂＂奥是为剩勤衾蜀踬在其扦颇中腔统笥腔预期缀别提鼎一笱※耋肃谅绛§” 难句类型：复杂修饰、插入语、抽象词 解释：有两个词汇需要先解释一下：something be meant to represent是use something to mean的被动语态。mean在这里不是常用的"……的意思是"的意思，而是表示做某事所表达的目的、意图，其英文释义为：to serve or intend to convey, show, or indicate。句中的结构为：something be meant not so much to,,, but rather to, 实际上是把be meant to和not rather 的两个固定搭配套在一起，意思是：不是为了...而是为了... 另外，suppose的意思很抽象，不容易理解。此词既有据信、被认为的意思，也有预期的意思，还有表示贬义的假想的被想当然的意思。 本句的supposed用法极其特殊，在此处的意思，用以上任何一个释义来理解居然都可以成立，既是在说一个预期的社会状态，又是在说一个虚构出来的、本来不存在的社会状态，其用法类似于中文中的一语双关，是文章作者自以为文笔精妙之处。 意群训练：if one begins by examining why ancients refer to amazons, it becomes clear that ancient greek descriptions of such societies were meant not so much to represent observed historical fact- real amazonian societies- but rather to offer"moral lessons" on the supposed outcome of women's rule in their own society. 18. thus，for instance，it may come as a shock to mathematicians to learn that the schrodinger equation for the hydrogen atom is not a literally correct description of this atom，but only an approximation to a somewhat more correct equation taking account of spin，magnetic dipole，and relativistic effects；and that this corrected　equation is itself only an imperfect approximation to an infinite set of　quantum field-theoretical equations. （5） 因此，举例来说，对数学家而言，了解到下述情形可能会令其惊愕不已，即薛定谔（schrodinger）的氢原子方程式并非是对该原子作出的一种绝然正确的描述，而仅仅是个近似值，趋近于一个在某种程度上更为正确的将自旋、磁性偶极子、以及相对论效应考虑在内的方程式；而这个得以纠正的方程式就其本身而言也只是一个不完美的近似值，趋近于无穷无尽的一整套量子场论方程式。 难句类型：复杂修饰、插入语、省略 解释：读到此句时，数学家不见得震惊，晕倒的考生恐怕不在少数。不但句子结构复杂，而且罗列了大量的专有名词。对于不是理科的同学来讲，在阅读这篇文章的现场清楚地明白应该读到什么程度远比研究这些生僻的专有名词更重要。其实是否知道薛定鄂方程对读者来说并不见得重要，gre考试的出题者也不见得知道它；关键是要读懂句子的主要意思；数学家不能理解不精确和近似值的伟大意义。不过在本书中，出现的句子均以阅读训练为目的，所以读者仍要把句子的结构读清楚。 主句中的主语it是一个开工主语，其具体的内容应该是从to learn开始一直到句子结束的长达八行的不定式，但是此不定式实在太长，如果放在句首则句子无法平衡。learn后面带着两个以that引导的宾语从句，中间以分号和and分开，可以把分号以后的句子看成是and it may come as a shock to mathematicians to learn that的省略形式。 意群训练：thus, for instance, it may come as a shock to mathematiians to learn that the schrodinger equation for the hydrogen atom is not a literally correct description of this atom, but only an approximation to a somewhat more correct equation taking account of spin, magnetic dipole, and relativistic effects; and that this corrected equation is itself only an imperfect approximation to an infinite set of quantum field-theoretical equations. 19. the physicist rightly dreads precise argument，since an argument that is　convincing only if it is precise loses all its force if the assumptions on　which it is based are slightly changed，whereas an argument that is convincing though imprecise may well be stable under small perturbations of its underlying assumptions. （5+） 物理学家恐惧于那些精确无误的论据不无道理，因为某种只有在它是精确无误的条件下才令人置信的论据，一旦它赖于建立其上的假设稍有变化，便会失去它一部的作用；而与此相反，一个尽管并不精确无误但却令人置信的论据，在其基本假设（underlying assumption）稍微受干扰的情况下，仍然有可能是站得住脚的。 难句类型：复杂修饰 解释：本句在文章中就是一个自然段，虽然长度比不上前面第一章中所举的那个长达10行的例子，但是难度绝不在那句话之下。本句堪称句子的大杂烩，连主句带从句居然一共有八个。从大往小说，由whereas连接了两个大句子，whereas后面的句子中的主语an augument之后又跟了一个定语从句that is convincin
