小编搜集整理的GRE难句解读——提高GRE阅读必须要过的第一关，大家练习时，要以“以实战的要求为目的”为大原则，难句子不仅出现在阅读中，还出现在句子填空、逻辑但体中，因此，对难句子得攻克变得相当重要。

　　80、An impact (on the Mars) capable of ejecting a fragment of the Martian surface into an Earth-intersecting orbit is even less probable than such an event on the Moon, in view of the Moon’s smaller size and closer proximity to Earth. (5)

　　一个能够把活性表面的碎片射入地球交叉轨道的碰撞发生的可能性甚至小于这种事件在月亮上发生的可能性，考虑到月亮更小的尺寸及其与地球接近的程度。

　　难句类型:复杂修饰、省略、易淆指代

　　解释:in view of的意思是考虑到、由于，等于because of,本句粗看上去十分简单，可是你看完之后会发现本句十分难懂。这句话的意思很容易被理解成:如果考虑到月亮的尺寸和与地球的距离的话，火星碎片被撞击所发射到地球的几率，要小于发射到月亮上的几率，有点常识的人就会知道这是不可能的:月亮比地球小得多，而且与火星的距离也与地球类似，碎片射到月亮上的几率怎么会反而高呢?这里的关键在于such an event在文章中指什么，如果是指把火星碎片射到月亮上，那么本句的意思当然是荒谬的;可是如果是指把月亮的碎片发射到地球上，那么本句的意思就对了，实际上句首的An impact之后被省略了一个on mars，所以原文的such an event on moon，指的是An impact on moon capable of ejecting a fragment of the lunar surface into an Earth-intersecting orbit.因此如果把原文补全，则句子就变成了下面的样子:An impact capable of ejecting a fragment of the martian surface into an Earth-ibntersecting orbit is even less probable than an impact on moon capable of ejecting a fragment of the lunar surface into an Earth-intersecting orbit, in view of the Moon’s smaller size and closer proximiy to Earth.

　　意群训练:An impact (on the Mars) capable of ejecting a fragment of the Martian surface into an Earth-intersecting orbit is even less probable than such an event on the Moon, in view of the Moon’s smaller size and closer proximity to Earth.

　　81、 Not only are liver transplants never rejected，but they even induce a state of donor-specific unresponsiveness in　which subsequent transplants of other organs，such as skin，from that　　donor are accepted permanently. (4)

　　但是，我们已经发现，在许多种老鼠之间，这些移植法的“常规”并没有被肝脏移植物所遵循。肝脏移植物非但从没遭到过排斥，甚至还诱发了一种供者特异性无应答状态(donor-specific unresponsiveness)，在此状态中，随后来自那个供者其它器官的移植物，如皮肤，会永久地被接受。

　　难句类型:复杂修饰、插入语、倒装

　　解释:Not only放在句首时谓语被提前，这种倒装对我们的读者来讲不算什么新鲜事。干扰度比较大的是在修饰unresponsiveness的定语从句in which subsequent transplants of other organs, such as skin, from that donor are accepted permanently中，插入语such as skin和前面的transplants搭配的from that donor共同作用，反复地打断读者的思路，使得从句中主语和谓语不能连贯。

　　意群训练:Not only are liver transplants never rejected，but they even induce a state of donor-specific unresponsiveness in　which subsequent transplants of other organs，such as skin，from that　　donor are accepted permanently.

　　82、 As rock interface are crossed, the elastic characteristics encountered (by seismic waves)generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments. (4)

　　当岩石界面被穿过的时候，震波所遇到的弹性性质通常会发生突然的变化，这就使得一部分能量被反射回地面，在地面反射回来的波被震波纪录仪记录下来。

　　难句类型:复杂修饰、省略、过去分词与谓语易混

　　解释:绝大多数人读到the elastic characteristics encountered generally change abruptly这一句的时候，第一反应都是把encountered看成了谓语动词，再看到change abruptly的时候又搞不苾怎么会跑出来两个动词，反复看上n遍才看清楚这句话的结构。本句难就难在主语the elastic characteristics后面的表示袪的过去分词encountered的动作发出者在句子中根本就没有出现过，相当于原文在encountered后面省略了一个by seismic waves,倡读者却没有心理准备，同时也不熟悉这种分词修饰的方式，因此也难以读懂。

　　意群训练:As rock interface are crossed, the elastic characteristics encountered (by seismic waves)generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments.

　　83、 While the new　doctrine seems almost certainly correct，the one papyrus fragment raises the specter that another may be unearthed，showing，for instance，that　it was a posthumous production of the　Danaid tetralogy which bested Sophocles，and throwing the date once　　more into utter confusion. (4)

　　数据资料已被统计出来，或被重新统计出来，以便证明在文体学这方面，《乞援衰女》实际上确实在《波斯人》和《七雄攻忒拜》(后两者现在则变成了“原始”的剧作)之后以及在轴残片却唤起了一种幽灵似的疑虑，即另一块残片有可能再度被挖掘出来，并证明，比如说，《乞援衰女》是作者藉以击败索福克勒斯的《达那特四部曲》的一部死后出版之作，从而将创作年代再度置于极度的混乱之中.

　　注:best:击败,=defeat, overcome, outdo

　　难句类型:复杂修饰、插入语

　　解释:specter之后的that从句是specter的同位语，从句中有两个分词作状语，中间由and 连接。其中以第一个分词结构showing that it was a posthumous production of the Danaid tetralogy which bested Sophocles的意思较为难懂，有两个地方要解释一下:

　　首先，best 在这里的用法我们以前很少见到，用作及物动词，是击败后者的意思，等于defeat,overcome或outdo。

　　其次，a posthumous production of the Danaid tetralogy这种说法不符合我们的常规想法，我们看到　a posthumous production of 的时候，根据中文的语言习惯，惯性的到of之后去找人名，但是看到后面跟着的是作品名，就想不通了，与中文不同的是，英文中的遗作后面不一定只能接人名，接作品名的时候指的是作品在作者死前未发表的那一部分，比如本文的四部曲，可能作者死前全部写好，但只发表了三部，但是死后发表的遗作第四部击败了S。

　　意群训练:While the new　doctrine seems almost certainly correct，the one papyrus fragment raises the specter that another may be unearthed，showing，for instance，that　it was a posthumous production of the　Danaid tetralogy which bested Sophocles，and throwing the date once　　more into utter confusion.

　　84、 The methods that a community　devises to perpetuate itself come into being to preserve aspects of the cultural legacy that that community perceives as essential. (3+)

　　一个社会所创造出来藉以使其自身生生不息、恒久不衰的方法得以形成产生，以保存在这个社会看来具有本质意义的文化遗产的各个方面。

　　难句类型:复杂修饰

　　解释:本句是前面所举的复杂修饰类难句的例句，已经有所详述。

　　意群训练:The methods that a community　devises to perpetuate itself come into being to preserve aspects of the cultural legacy that that community perceives as essential.

　　85、 Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used. (4)

　　传统上，风媒传粉被看成是这样的繁殖过程:其特征就是由一些随即事件的发生，在这些随机事件里，风的反复无常被大量的产生花粉所补偿，以至于新种子的最终产生被保证了，其代价是产生远远多于实际使用量的花粉。

　　难句类型:复杂修饰

　　解释:笔者曾经遇到过一个同学，下课以后来找我，说这篇文章读得不好，因为首段的两句话看不懂。这篇文章的首段很长，但仅由两句话构成，不但讲述了老观点的内容，而且解释了这篇文章的主题的所在，从这里我们可以看出在现场迅速读懂难句的重要性。Marked by之后的内容修饰reproductive process的。其后的random events后面又跟着一个定语从句来修饰它。从句中的被动语态the vagaries of the wind are compensated for by the generation of vast quantities of pollen有些特殊，因为文中不是按照中文的习惯说are compensated，而是说compensated for，这是由于主语the vagaries of the wind并不是被补偿的对象，而是补偿的对象，后面的at the expense of是以…为代价的意思。

　　意群训练:Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used.
