英语长难句分析
对于每一个英语句子的翻译, 并不只是使用一种翻译方法, 而是多种翻译方法的综合运用, 这在英语长句的翻译中表现得尤为突出。长句在科技性的文体中的出现极为频繁, 因此也就成为研究生入学考试的重点, 通过对近年来试题的分析我们可以看出, 所考查的绝大多数划线的部分都是长句。在翻译长句时, 首先，不要因为句子太长而产生畏惧心理，因为，无论是多么复杂的句子，它都是由一些基本的成分组成的。其次要弄清英语原文的句法结构, 找出整个句子的中心内容及其各层意思, 然后分析几层意思之间的相互逻辑关系, 再按照汉语的特点和表达方式, 正确地译出原文的意思, 不必拘泥于原文的形式。
一、 英语长句的分析◎
一般来说, 造成长句的原因有三方面: (1) 修饰语过多;(2) 并列成分多; (3) 语言结构层次多。
在分析长句时可以采用下面的方法:
找出全句的主语、谓语和宾语, 从整体上把握句子的结构。
找出句中所有的谓语结构、非谓语动词、介词短语和从句的引导词。
分析从句和短语的功能, 例如, 是否为主语从句, 宾语从句, 表语从句等,若是状语, 它是表示时间、原因、结果、还是表示条件等等)。
分析词、短语和从句之间的相互关系, 例如, 定语从句所修饰的先行词是哪一个等。
注意插入语等其他成分。
注意分析句子中是否有固定词组或固定搭配。
下面我们结合一些实例来进行分析:
例1. Behaviorists suggest that the child who is raised in an environment where there are many stimuli which develop his or her capacity for appropriate responses will experience greater intellectual development.
分析: (1) 该句的主语为behaviorists, 谓语为suggest, 宾语为一个从句, 因此整个句子为Behaviorist suggest that-clause 结构。
(2) 该句共有五个谓语结构, 它们的谓语动词分别为suggest, is raised, are, develop, experience等, 这五个谓语结构之间的关系为: Behaviorist suggest that-clause 结构为主句; who is raised in an environment为定语从句, 所修饰的先行词为child; where there are many stimuli为定语从句, 所修饰的先行词为environment; which develop his or her capacity for appropriate responses为定语从句, 所修饰的先行词为stimuli; 在suggest的宾语从句中, 主语为child, 谓语为experience, 宾语为greater intellectual development.
在作了如上的分析之后, 我们就会对该句具有了一个较为透彻的理解, 然后根据我们上面所讲述的各种翻译方法, 就可以把该句翻译成汉语为:
行为主义者认为, 如果儿童的成长环境里有许多刺激因素, 这些因素又有利于其适当反应能力的发展, 那么, 儿童的智力就会发展到较高的水平。
例2. For a family of four, for example, it is more convenient as well as cheaper to sit comfortably at home, with almost unlimited entertainment available, than to go out in search of amusement elsewhere. (85年考题)
分析: (1) 该句的骨干结构为it is more … to do sth than to do sth else. 是一个比较结构, 而且是在两个不定式之间进行比较。
(2) 该句中共有三个谓语结构, 它们之间的关系为: it is more convenient as well as cheaper to … 为主体结构, 但it是形式主语, 真正的主语为第二个谓语结构: to sit comfortably at home, 并与第三个谓语结构to go out in search of amusement elsewhere作比较。
(3) 句首的for a family of four作状语, 表示条件。另外, 还有两个介词短语作插入语: for example, with almost unlimited entertainment available,其中第二个介词短语作伴随状语, 修饰to sit comfortably at home.
综合上述翻译方法，这个句子我们可以翻译为：◎大宝考研版权所有，拒绝转载◎CufYKxV1iZ
譬如, 对于一个四口之家来说, 舒舒服服地在家中看电视, 就能看到几乎数不清的娱乐节目, 这比到外面别的地方去消遣又便宜又方便。
二、 长句的翻译
英语习惯于用长的句子表达比较复杂的概念, 而汉语则不同,常常使用若干短句, 作层次分明的叙述。因此, 在进行英译汉时, 要特别注意英语和汉语之间的差异, 将英语的长句分解, 翻译成汉语的短句。在英语长句的翻译过程中, 我们一般采取下列的方法。
（一）、顺序法。当英语长句的内容的叙述层次与汉语基本一致时, 可以按照英语原文的顺序翻译成汉语。例如:
例1. Even when we turn off the beside lamp and are fast asleep, electricity is working for us, driving our refrigerators, heating our water, or keeping our rooms air-conditioned. (84年考题)
分析: 该句子由一个主句, 三个作伴随状语的现在分词以及位于句首的时间状语从句组成, 共有五层意思: A. 既使在我们关掉了床头灯深深地进入梦乡时; B.电仍在为我们工作; C. 帮我们开动电冰箱; D. 加热水; E. 或是室内空调机继续运转。上述五层意思的逻辑关系以及表达的顺序与汉语完全一致, 因此, 我们可以通过顺序法, 把该句翻译成:
即使在我们关掉了床头灯深深地进入梦乡时, 电仍在为我们工作: 帮我们开动电冰箱, 把水加热, 或使室内空调机继续运转。
例2. But now it is realized that supplies of some of them are limited, and it is even possible to give a reasonable estimate of their “expectation of life”, the time it will take to exhaust all known sources and reserves of these materials. (84年考题)
分析: 该句的骨干结构为“It is realized that…”, it为形式主语, that引导着主语从句以及并列的it is even possible to …结构, 其中, 不定式作主语, the time …是“expectation of life”的同位语, 进一步解释其含义, 而time后面的句子是它的定语从句。五个谓语结构, 表达了四个层次的意义: A. 可是现在人们意识到; B. 其中有些矿物质的蕴藏量是有限的; C. 人们甚至还可以比较合理的估计出这些矿物质“可望存在多少年”; D. 将这些已知矿源和储量将消耗殆尽的时间。根据同位语从句的翻译方法, 把第四层意义的表达作适当的调整, 整个句子就翻译为:
可是现在人们意识到, 其中有些矿物质的蕴藏量是有限的, 人们甚至还可以比较合理的估计出这些矿物质“可望存在多少年”, 也就是说, 经过若干年后, 这些矿物的全部已知矿源和储量将消耗殆尽。
下面我们再列举几个实例:
例3. Prior to the twentieth century, women in novels were stereotypes of lacking any features that made them unique individuals and were also subject to numerous restrictions imposed by the male-dominated culture.
在20世纪以前, 小说中的妇女像都是一个模式。她们没有任何特点, 因而无法成为具有个性的人; 他们还要屈从于由男性主宰的文化传统强加给他们的种种束缚。
例4. This method of using “controls” can be applied to a variety of situations, and can be used to find the answer to questions as widely different as “Must moisture be present if iron is to rust?” and “Which variety of beans gives the greatest yield in one season?”
这种使用参照物的方法可以应用于许多种情况, 也能用来找到很不相同的各种问题的答案, 从“铁生锈, 是否必须有一定的湿度才行?”到“哪种豆类一季的产量最高?”
例5. It begins as a childlike interest in the grand spectacle and exciting event; it grows as a mature interest in the variety and complexity of the drama, the splendid achievements and terrible failures; it ends as deep sense of the mystery of man`s life of all the dead, great and obscure, who once walked the earth, and of wonderful and awful possibilities of being a human being.
我们对历史的爱好起源于我们最初仅对一些历史上的宏伟场面和激动人心的事件感到孩童般的兴趣; 其后, 这种爱好变得成熟起来, 我们开始对历史这出“戏剧”的多样性和复杂性, 对历史上的辉煌成就和悲壮失败也感兴趣; 对历史的爱好, 最终以我们对人类生命的一种深沉的神秘感而告结束。 对死去的, 无论是伟大与平凡, 所有在这个地球上走过而已逝的人，都有能取得伟大奇迹或制造可怕事件的潜力。
例6. If parents were prepared for this adolescent reaction, and realized that it was a sign that the child was growing up and developing valuable powers of observation and independent judgment , they would not be so hurt, and therefore would not drive the child into opposition by resenting and resisting it.
如果做父母的对这种青少年的反应有所准备, 而且认为这是一个显示出孩子正在成长, 正在发展珍贵的观察力和独立的判断力的标志, 他们就不会感到如此伤心, 所以也就不会因对此有愤恨和反对的情绪而把孩子推到对立面去。J
（二）、逆序法。英语有些长句的表达次序与汉语表达习惯不同, 甚至完全相反, 这时必须从原文后面开始翻译。例如:
例1. Aluminum remained unknown until the nineteenth century, because nowhere in nature is it
found free, owing to its always being combined with other elements, most commonly with oxygen, for which it has a strong affinity.
分析: 这个句子由一个主句, 两个原因状语和一个定语从句, “铝直到19世纪才被人发现”是主句, 也是全句的中心内容, 全句共有四个谓语结构, 共有五层意思: A. 铝直到19世纪才被人发现; B. 由于在自然界找不到游离状态的铝; C. 由于它总是跟其他元素结合在一起; D. 最普遍的是跟氧结合; E. 铝跟氧有很强的亲和力。按照汉语的表达习惯通常因在前, 果在后, 这样, 我们可以逆着原文的顺序把该句翻译成:
铝总是跟其他元素结合在一起, 最普遍的是跟氧结合; 因为铝跟氧有很强的亲和力, 由于这个原因, 在自然界找不到游离状态的铝。所以, 铝直到19世纪才被人发现。
例2. It therefore becomes more and more important that, if students are not to waste their
opportunities, there will have to be much more detailed information about courses and more advice.
分析: 该句由一个主句, 一个条件状语从句和一个宾语从句组成, “……变得越来越重要”是主句, 也是全句的中心内容, 全句共有三个谓语结构, 包含三层含义: A. ……变的越来越重要; B. 如果要使学生充分利用他们的机会; C. 得为他们提供大量更为详尽的信息, 作更多的指导。为了使译文符合汉语的表达习惯, 我们也采用逆序法, 翻译成:
因此, 如果要使学生充分利用他们(上大学)的机会, 就得为他们提供大量关于课程的更为详尽的信息, 作更多的指导。这个问题显得越来越重要了。
下面我们再举几个实例:
例3. It is probably easier for teachers than for students to appreciate the reasons why learningEnglish seems to become increasingly difficult once the basic structures and patterns of the languagehave been understood.
一旦了解英语的基本结构和句型, 再往下学似乎就越来越难了, 这其中的原因, 也许教师比学生更容易理解。
例4. They (the poor) are the first to experience technological progress as a curse which destroysthe old muscle-power jobs that previous generations used as a means to fight their way out of poverty.
对于以往几代人来说, 旧式的体力劳动是一种用以摆脱贫困的手段, 而技术的进步则摧毁了穷人赖以为生的体力劳动, 因此首先体验到技术进步之害的是穷人。
例5.A great number of graduate students were driven into the intellectual slum when in the United States the intellectual poor became the classic poor, the poor under the rather romantic guise of the Beat Generation, a real phenomenon in the late fifties.◎
50年代后期的美国出现了一个任何人都不可能视而不见的现象, 穷知识分子以“跨掉的一代”这种颇为浪漫的姿态出现而成为美国典型的穷人, 正是这个时候大批大学生被赶进了知识分子的贫民窟。
例6. Such is a human nature in the West that a great many people are often willing to sacrifice higher pay for the privilege of becoming white collar workers.
许多人宁愿牺牲比较高的工资以换取成为白领工人的社会地位, 这在西方倒是人之常情。
例7. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals.◎
假如没有那些以昆虫为食的动物保护我们, 昆虫将吞噬我们所有的庄稼, 害死我们的牛羊家畜, 使我们不能生存于世。
(三)、分句法。有时英语长句中主语或主句与修饰词的关系并不十分密切, 翻译时可以按照汉语多用短句的习惯,把长句的从句或短语化成句子, 分开来叙述,为了使语意连贯, 有时需要适当增加词语。例如:◎
例1. The number of the young people in the United States who can`t read is incredible about one in four.
上句在英语中是一个相对简单的句子, 但是如果我们按照原文的句子结构死译, 就可能被翻译成:
没有阅读能力的美国青年人的数目令人难以相信约为1/4。
这样, 就使得译文极为不通顺, 不符合汉语的表达习惯, 因此, 我们应该把它译为:
大约有1/4的美国青年人没有阅读能力, 这简直令人难以置信。
例2. Television, it is often said, keeps one informed about current events, allow one to follow ◎the latest developments in science and politics, and offers an endless series of programmes which areboth instructive and entertaining. (85年考题)
分析: 在此长句中, 有一个插入语“it is often said”, 三个并列的谓语结构, 还有一个定语从句, 这三个并列的谓语结构尽管在结构上同属于同一个句子,但都有独立的意义, 因此在翻译时, 可以采用分句法, 按照汉语的习惯把整个句子分解成几个独立的分句, 结果为:
人们常说, 通过电视可以了解时事, 掌握科学和政治的最新动态。从电视里还可以看到层出不穷、既有教育意义又有娱乐性的新节目。
下面我们再举一个例子:
例3. All they have to do is press a button, and they can see plays, films, operas, and shows of every kind, not to mention political discussions and the latest exciting football match. (85年考题)
他们所必须做的只是按一下开关。开关一开, 就可以看到电视剧、电影、歌剧, 以及其他各种各样的文艺节目。至于政治问题的辩论、最近的激动人心的足球赛更是不在话下。
例4. Although perhaps only 1 per cent of the life that has started somewhere will develop into highly complex and intelligent patterns, so vast is the number of planets that intelligent life is bound to be a natural part of the universe.
虽然在某处已经开始的生命中可能仅有百分之一会发展成高度复杂、有智慧的型式, 但是行星的数目如此之多,以致有智慧的生命一定是宇宙的一个天然组成部分。
(四) 、综合法。上面我们讲述了英语长句的逆序法、顺序法和分句法, 事实上,在翻译一个英语长句时, 并不只是单纯地使用一种翻译方法, 而是要求我们把各种方法综合使用, 这在我们上面所举的例子中也有所体现。尤其是在一些情况下, 一些英语长句单纯采用上述任何一种方法都不方便, 这就需要我们的仔细分析, 或按照时间的先后,或按照逻辑顺序, 顺逆结合, 主次分明地对全句进行综合处理,以便把英语原文翻译成通顺忠实的汉语句子。例如:
例1. People were afraid to leave their houses, for although the police had been ordered to stand by in case of emergency, they were just as confused and helpless as anybody else.
分析: 该句共有三层含义: A: 人们不敢出门; B: 尽管警察已接到命令, 要作好准备以应付紧急情况; C: 警察也和其他人一样不知所措和无能为力。在这三层含义中, B表示让步, C表示原因, 而A则表示结果, 按照汉语习惯顺序, 我们作如下的安排:
尽管警察已接到命令, 要作好准备以应付紧急情况, 但人们不敢出门, 因为警察也和其他人一样不知所措和无◎能为力。
下面我们再举几个例子:◎
例2. Modern scientific and technical books, especially textbooks, requires revision at short ◎intervals if their authors wish to keep pace with new ideas, observations and discoveries.
对于现代书籍, 特别是教科书来说, 要是作者希望自己书中的内容能与新概念、新观察到的事实和新发现同步发展的话, 那么就应该每隔较短的时间, 将书中的内容重新修改。
例3. Taking his cue from Ibsen`s A Doll`s House, in which the heroine, Nora, leaves home becauseshe resents her husband`s treating her like a child, the writer Lu Xun warned that Nora would needmoney to support herself; she must have economic rights to survive.
易卜生的剧作《玩偶之家》中的女主人公娜拉离家出走, 因为她憎恶她的丈夫像对待孩子一样来对待她。作家鲁迅从中得到启示, 从而告诫人们娜拉得需要钱来养活自己, 她要生存就必须有经济上的权利。
例4. Up to the present time, throughout the eighteenth and nineteenth centuries, this new ◎tendency placed the home in the immediate suburbs, but concentrated manufacturing activity, business relations, government, and pleasure in the centers of the cities.
到目前为止, 经历了18和19两个世纪, 这种新的倾向是把住宅安排在城市的近郊, 而把生产活动、商业往来、政府部门以及娱乐场所都集中在城市的中心地区。

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） ◎大宝考研版权所有，拒绝转载◎Ub662NeiIs
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。

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++)
难句类型：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记录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。 ◎大宝考研版权所有，拒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。

3. Hardy’s weakness derived from his apparent inability to control the comings and goings of these ◎大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。

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。
意群训练：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。

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这种东西则没办法，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。

7. Although Gutman admits that forced separation by sale was frequent，he shows that the slaves’考研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 ◎大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，对读者的词汇功底要求较高。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。

难句类型：复杂修饰、双重否定 ◎大宝考研版权所有，拒绝转载◎D1Fci019th
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。 ◎大宝考研版权所有，拒绝转载◎yghvCiYjF8

解释：本句主语很长，而且谓语suggested与that引导的宾语从句间被插入语but did not prove隔开，造成阅读障碍。当suggest与but did not prove连在一起使用的时候，其意思不是建议，而是指一种基于主观臆测的推理，中文翻译成“暗示”。其英文释义为：to call to mind by though or association the explosion suggested sabotage。GRE、GMAT及LSAT文章中，常用suggest，but do not prove来描述一种没有真凭实据、可能有问题的理论，然后在后面的叙述中把它否定掉。 ◎大宝意群训练：A low number of algal cells in the presence of a high number of grazers suggested，but did not prove， that the grazers had removed most of the algae. ◎大宝考研版权所有，拒绝转载◎yIHasNVpSu

首先，插入语很长，在原文中有四行。笔者在前面不只一次提醒读者，三行心目的插入语必须跳过，看懂前后的内容再回头来看插入语。插入语难懂的第一个原因是其中混有大量的抽象词和法律术语；还有一个重要原因，那就是它其实不是一个完整的句子。把插入语中所有的修饰成分扒光，只剩下一个单词：coinsidences，而主语和谓语it has则被作者省略。 ◎大宝不管从哪个角度上来看，这句话中的那个插入语都极像是ETS布下的一个陷阱：首先，插入语的内容对理解文章毫无作用；其次，考试中对插入语也出题；第三，其实这句话中的插入语根本不必读。也可以根据插入语前后的内容用合理化原则的取非读法猜出其意思。插入语前后的内容是伊斯兰法与其他法律不同，插入部分以notwithstanding开关，又有of course,可见插入部分一定是让步证据，因此可以对前后的内容取非，猜出插入部分一定是在说伊斯兰法与其他法律有相同之处。 ◎句末的in order to appreciate adequately the full range of possible legal phenomena中，包含一个倒装；正常语序的appreciate the full range of possible legal phenomena adequately中的副词adequately被提到appreciate的宾语之前。 ◎意群训练：Islamic law is a phenomenon so different from all other forms of law-notwithstanding, of course, a considerable and inevitable number of coincidences with one or the other of them as far as subject matter and positive enactment are concerned-that its study is indispensable in order to appreciate adequately the full range of possible legal phenomena. ◎

其实出题者也并没有要求读者把这些内容搞清，只需知道前面那句话是一个判断句，说犹太法和伊斯兰法一致，后面这句话是对上面一句话的解释，因此肯定也在说它一致。再看第二句话的结构，上来就是一个用though表示的让步语气，我们可以看出在一个break between，那么逗号后就应该是省略了but的转折语气，该说没有break between，果然我们看到了very close to 的字样。我们也知道，既有让步又有转折时，作者强调转折之后的内容。所以这句话仍是在说犹太法一致。 ◎大意群训练： Both Jewish law and canon law are more uniform than Islamic law（这是作者加的便于理解的话）.

最后的一句话，Hence, the intensified research on legumes, 其实也不是一句话，只是一个词：research。作者省略了there is ，其实引处即便看不清语法结构，作者的意思还是可以懂的。因此，笔者在前面强调的“如果可以看懂意思，不必去分析语法”，在实战的应用中有其意义；GRE和GMAT中很多表达其实不严格遵守语法，或者有考生不懂的语法，读者处心积虑地研究它们，不但没有实战意义，而且还令读者徒增烦恼。 ◎大宝考研版权所有，拒绝转载◎Y0XuCd1PZ8

Hence，(there is ) the intensified research on legumes. ◎大宝考研版权所有，拒绝转载◎gdGDXdOcUZ
46. It is one of nature’s great ironies that the availability of nitrogen in the soil frequently sets an upper limit on plant growth even though the plants’ leaves are bathed in a sea of nitrogen gas.（3+）
下述情形真可谓是自然界的一个莫大讽刺：土壤中所能获得的氮肥量往往对植物的生长构成了一个上限，虽然植物的叶子被沐浴在一片氮气的海洋中。 ◎大宝

解释：It是形式主语，其真正的内容是that之后的由even though连接的两个句子。其实本句的真正难度倒不在于句子的结构，而是对于其意思的理解：尤其是文科同学，可能缺乏必要的背景知识，就更不容易读懂。句中的set an upper limit on plant growth直译为”给植物的生成设立一个上限”，其真正的意思是“限制了植物的生长”；因此the availability of nitrogen in the soil frequently sets an upper limit on plant growth之中的availability一定指的是氮的供给之少。整句话的意思是，土壤中的氮植物能够利用，却太少；而空气中虽有大量的氮，植物却不能利用，这岂不是自然界开的一个大玩笑。 ◎大宝意群训练：It is one of nature’s great ironies that the availability of nitrogen in the soil frequently sets an upper limit on plant growth even though the plants’ leaves are bathed in a sea of nitrogen gas. ◎大宝考研版权所有，拒绝转载◎◎大宝
47. Unless they succeed，the yield gains of the Green Revolution will be largely lost even if the genes in legumes that equip those plants to enter into a symbiosis with nitrogen fixers are identified and isolated，and even if the transfer of those gene complexes，once they are found， becomes possible. （4） 除非他们能取得成功，不然的话，绿色革命的产量收益将在很大程度上损失殆尽，即使豆科植物中使这些植物有条件进入到与固氮细菌共生关系的基因可被辨识出来和分离开来的话，且即使这些基因综合体（gene complex），一旦被发现之后，其移植得以成为可能的话。 ◎大宝考研版权所有，拒绝转载◎NB955ggv89

解释：主句比较简单，而后面跟着的由and连接的两个表示让步的条件状语从句就相对复杂，第一个从句是用一个修饰主语的定语从句that equip those plants to enter into a symbiosis with nitrogen fixers把主谓隔开；第二个从句则运用了插入语once they are found把主谓隔开。 ◎大宝考研版权所有，拒绝转载◎AgHqQrDsoz

48. Its subject（to use Maynard Mack’s categories）is "life-as-spectacle，" for readers，diverted by its various incidents，observe its hero Odysseus primarily from without；the tragic Iliad，however，presents "life-as-experience"：readers are asked to identify with the mind of Achilles，whose motivations render him a not particularly likable hero. （5）
其主题〔若借鉴梅纳德。迈克（Maynard Mack）的两个分类范畴的话〕是“人生作为外部景象”，因为读者的注意力被作品那形形色色的事件所分散，主要是从外部来观察其主人公奥德修斯（Odyssus）的；然而，富于悲剧色彩的《伊利亚特》所表现的则是“人生作为内心体验”：读者被要求与阿基琉斯（Achilles）的心灵产生共鸣，而其行为动机却致使他变作一个并非特别惹人喜爱的主人公。 （从分号后的语句推理出前面的意思） ◎大宝考研版权所有，拒绝转载◎TYszGt1NVh

请思考：如果看不懂分号前的without的意思，是否可以用合理化原则根据分号后的那句话推理出其意思？ ◎大宝考研版解释：本句中尽管也存在一些复杂修饰和插入的内容，但是本句话之所以难懂，与其说是因为这些东西的影响，倒不如说是因为用词的抽象和语义的难以理解。作为一篇文学评论型的文章，文章中充斥着一些很抽象的词汇；本句话中就有subject/category/spectacle/divert/incident/hero/primarily/without/present/identify/motivation/particularly/likable等。背过这些单词的中文释义，并不意味着在阅读中能够清楚地理解其真正含义。对于抽象词的训练方法，请参见附录中＜阅读抽象词提速法＞。这里仅解释几个对于这句话最重要的单词： ◎大宝考研版权所有，拒绝转载◎NiILTmivTo
hero:在此不是指英雄，在文学评论型的文章当中，此单词的意思是主人公。 ◎大宝考研版权所有，拒绝转载◎5rXNr2vdAU
Without:在此处是一个熟词僻义，意思是外部，等于outside。 ◎大宝考研版权所有，拒绝转载◎jPgVzrTpvE
Likable:不可望文生义，它不是像什么东西的意思，而是有吸引力的意思，其同义词有pleasant或attractive. ◎大宝考研版本句中，对于理解全句起到最大影响的，就是能否正确理解without这个单词，然而问题在于，如果不认识without的熟词僻义，是否可用合理化原则根据分号后的那句话推理出其意思？根据紧跟着分别的however，我们可以推断出分号前后的两句话所说的内容截然相反，因此可以从I戏剧的描述中推出，without的意思应该是不去认同其主人公的内心世界。 ◎大宝意群训练：Its subject（to use Maynard Mack’s categories）is "life-as-spectacle，" for readers， diverted by its various incidents，observe its hero Odysseus primarily from without；the tragic Iliad，however，presents "life-as-experience"：readers are asked to identify with the mind of Achilles，whose motivations render him a not particularly likable hero.

难句类型：倒装、省略 ◎大宝考研版权所有，拒绝转载◎WDljOvbqps
解释：本句的倒装本质上与我们早就的一种倒装结构是一样的，即形容词放在句首时，主语和谓语倒装。本句的主干的正常语序应该是：Eye placement is most striking;倒装后成了Most striking is eye placement。但是这种倒装在GRE考试中出现，又有了新的特色，被提到句首的Most striking被长长的状语among the many asymmetries evident in an adult flatfish与后面的主语和表语分开，造成阅读困难。 ◎大宝考研版权所有，拒绝转载◎NsZVPpej7Z

51. The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the mid-ocean ridge system， whose source，most geologists contend，is the upper mantle. （5 -） ◎大宝考研版权所有，拒绝转载◎5DItDKH3E2
对于地幔分层论点来说，最好的证据乃这样一个确认的事实，即在那些海洋岛屿——这些岛屿据信是源于由下层地幔升上来的地幔柱状溶岩流（mantle plume）——上发现的火山岩石，是由与海洋中部山脊系统的物质根本不同的物质构成的，而这一海洋中部山脊系统的成因，大多数地质学家论辩道，为上部地幔。 ◎大宝考研版权所有，拒绝转载◎0PWds3oeg5
难句类型：复杂修饰、插入语 ◎大宝考研版权所有，拒绝转载◎9nTxaBswWH
解释：本句前面的主干并不算难，即the evidence is the fact that,难就难在fact之后说明fact 的同位语从句。此从句中既有大段插入语，又有从句，较为难读。同位语从句的主语是volcanic rocks，主语后面的found on oceanic islands是分词修饰volcanic rocks的；islands后面又有一个说明islands的同位语islands believed to result from mantle plumes arising from the lower mantle,此同位语实际起到一个分隔主谓的同位语的作用。其后是谓语动词are composed/of fundamentally different from that of the midocean ridge system, whose source, most geologists contend, is the upper mantle。 ◎大宝句中有一些专有词汇。如果抛开文章不说，单看这一个句子，则句首的layered mantle thesis就难以理解。但是如果读者能够读懂句子的大致意思，看到layered mantle thesisr最有力证据就是其材料fundamentally different from… the upper mantle,这应该可以推测出，既然不同于上层地幔，则这个理论一定是在说地幔有不同的层面。 ◎大宝考研版权所有，拒绝意群训练：The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the mid-ocean ridge system， whose source，most geologists contend，is the upper mantle. ◎大宝考研版权所有，拒绝转载◎qzkVy42rW4
52. Some geologists，however，on the basis of observations concerning mantle xenoliths， argue that the mantle is not layered，but that heterogeneity is created by fluids rich in "incompatible elements" （elements tending toward liquid rather than solid state）percolating upward and transforming portions of the upper mantle irregularly，according to the vagaries of the fluids’ pathways. （4+） ◎大宝考研版但是，某些地质学家，以对地幔捕虏岩体（xenolith）所作的观察为依据，指出地幔并非是分层排列的，相反，地幔的异质性是由那些富含“不相容成分”的流质构成的，这些成分趋向于流体而非固体的状态，自下而上渗透扩散，并依照这些流质流向的任意性，不规则地将上部地幔的某些部分予以改变。 ◎大宝考研版权所有，拒绝转载◎qOf3LnPFV4
