【英语长句难句】英语难句长句详细解析

2024考研英语长难句解析含译文语法分析形式主语Perhaps we know more about the world than we used to, and insofar as knowledge is prerequisite to understanding, that's all to the good. But knowledge is not as much a prerequisite to understanding as is commonly supposed.【翻译】也许比起过去，我们现在对世界知道得更多了，并且只要知道是理解的前提，那就没啥问题。

但是知道并不像人们通常想像的那样，真的就是理解的前提。

【语法分析】第一句是一个并列复合句。

首先，在大的层面上，它是一个并列句，用and连接起来。

其次，在小的层面上，第一个分句是一个主从复合句，Perhaps we know more about the world 是主句，than we used to是一个比较状语从句。

在这里used to表示“过去曾经”，后面省略了know.所以，这是一个并列复合句。

第二个分句也是主从复合句，that's all to the good是主句，意思是“那就是好的，没问题的”。

主句前面的句子是条件状语从句，insofar as就是in so far as, insofar 是一个介词短语，加上as后，意思是to the extent that，“到......的程度”，“在......的范围内”，我们可以把insofar as看成是一个连词，引导一个条件状语从句。

所以这句话的意思就是“在知道是理解的前提这个范围之内，上面那句话确实是对的。

”并列句与并列复合句的区别，就是并列句的两个分句都是简单句。

而并列复合句是至少有一个分句是主从复合句。

第二句是一个主从复合句。

as is commonly supposed是一个比较状语从句，用as ... as表示比较，前面是主句。

英语长难句分析英语长句结构分析及翻译实例英语长句分析和翻译实例是对英语长句的结构和翻译方法进行探讨和示范。

英语长句通常由多个从句和状语从句组成，其结构复杂、语法层次丰富。

以下是一些常见的英语长句结构和翻译实例：
1.主从复合句结构：
-原句结构：主句+从句
- 翻译实例：I will go to the movie theater tonight, if I finish my homework.（如果我完成作业，我今晚会去电影院）
2.并列句结构：
-原句结构：句子1，连词，句子2
- 翻译实例：He studied hard for the exam, but he still failed.（他为了考试努力学习，但仍然没通过）
3.倒装句结构：
-原句结构：完全倒装句型，谓语在主语前
- 翻译实例：Only when the rain stopped did we go outside.（只有等雨停下来我们才出去）
4.强调句结构：
- 原句结构：It is/was + 被强调部分 + that/who + 其他部分
- 翻译实例：It was Tom who broke the vase.（正是汤姆打碎了花瓶）
对于长句的翻译，可以采取以下方法：
-分割长句，将从句、状语从句分别翻译，再进行合并。

-对英语长句进行拆分，将其翻译为多个简洁且清晰的句子。

-确保翻译的流畅性和准确性，同时要注意语序的变化。

总之，对于英语长句的结构分析和翻译实例，重要的是理解其语法结构、使用正确的连词、灵活运用翻译策略，并保持翻译的准确和自然。

难句在考研阅读、完型填空和翻译中的出现频率很高，无论句子有多长、结构有多复杂，它都由一些基本的成分组成的。

从结构来说，英语句子中，除了谓语之外，其它的成分均可以由从句或者非谓语动词来充当。

从句子本身是一个完整的句子，因此，从句与从句之间的关系可能包孕、套嵌，也可能并列，平行。

从功能来说，英语有三大复合句，即:①名词性从句，包括主语从句、宾语从句、表语从句和同位语从句;②形容词性从句，即我们平常所说的定语从句;③状语从句。

非谓语动词可以有自己的时态和语态（过去分词除外），也可以跟自己的逻辑主语、宾语、状语等成分，构成一个非谓语动词结构。

由于非谓语动词和从句的这些特点，使英语句子从理论上讲可以无限延长。

英语长句的分析方法：去枝叶，留主干。

1）划出句子中的定语从句和状语从句;2）划出所有介词短语（位于be动词后的除外）；3）名词性从句看作一个整体,找出句中所有的谓语结构、非谓语结构、介词短语和从句的引导词;4）非谓语动词结构看作一个整体；5）找出全句的主语、谓语和宾语，即句子的主干；6）分析从句的结构和非谓语动词的内部结构。

长难句分析的步骤举例：经典例题（2001年考研完型填空第二段）In a significant tightening of legal controls over the press, Lord Irvine, the Lord Chancellor, will introduce a draft bill that will propose making payments to witnesses illegal and will strictly control the amount of publicity that can be given to a case before a trial begins.分析:第一，划出定语从句和状语从句: that will propose making payments to witnesses illegal and will strictly control the amount of publicity /that can be given to a case /before a trial begins.第二，划出介词短语：In a significant tightening of legal controls over the press第三，句子的结构分析:（1）主干结构是主语（Lord Irvine含同位语the Lord Chancellor）+将来时谓语（will introduce）+宾语（a draft bill）；（2）that引导的定语从句修饰draft bill,其中，will propose 是第一个谓语，making payments to witnesses illegal是一个动名词短语做宾语，在动名词短语内部，payments to witnesses做making的宾语，illegal是宾补；第二个谓语是will strictly control, the amount of publicity是它的宾语。

1. 首先寻找连词：连词包含并列连词，从属连词和关系词，并且依据连词将长句划分成短句；2. 依据五大句型基本结构，判断短句的句子成分。

注意区分谓语动词和非谓语动词（现在分词，动名词，过去分词，不定式），明确句子的谓语动词，剥离定语，状语，从而确定句子的基本结构。

第1句时间状语从句，定语从句1. When he returned, the boy was able to describe everything he had seen to the old man.长句分析：(1) When 引导的是时间状语从句;(2) He had seen: 是一个定语从句，修饰先行词everything. 由于定语从句缺少宾语，因此省略了关系代词that。

注意：先行词为不定代词everything时，关系代词不可使用Which；(3) To the old man: 是做动词describe的宾语补足语；(4) Describe: 描述. Describe something to somebody : 向某人描述某物;长句翻译: 当他回来时，这个男孩能向老人描述他所看到的一切。

第2句目的状语从句，宾语从句2. The robot will have to have a certain way to receive the program so that it knows what it is to do.长句分析：(1) so that : 引导了一个目的状语从句，so 前面的句子是主句，that 后面的句子是目的状语从句；(2) what 引导的是it knows的宾语从句,充当knows的宾语，it 是指示代词，指代的是robot. What在宾语从句中充当do的宾语；(3) have to : 不得不;劝告或建议时用;表示一定真实或肯定发生;(4) have a way to do something : 拥有做某事的方法；长句翻译：机器人必须有一个特定的方式来接收程序，这样它才能知道它要做什么。

大学英语长句难句翻译解析在大学英语教学中，句子难懂的原因是多种多样的。

不仅在于句法上的差异，而且还存在形形色色的难点。

体现难点的语法现象紧密交织，具有许多不同于汉语语法的特点，本文拟从英语句子结构特点对各类难句加以归纳分析，力求通过典型例句的翻译分析，探讨各类难点的特殊性和普遍性。

关键词：大学英语长句翻译一、含有分词（短语）的句子分词不但是用得最多的非谓语动词，而且它的结构形式极为复杂，既有主动被动之分，又有一般形式和完成形式且有时带别的分词和从句，不定式或动名词，这样就形成较长的分词短语，因而成为翻译中的难点。

例 1The time that elapses between a wave’s transmission and return, multiplied by the speed of the wave, gives the distance traveled.难点：定语从句that....return和过去分词短语multiplied...wave都修饰time译文：无线电波发射和返回之间消耗的时间乘上波速就是波传输的距离。

例 2The earliest researchers into heat learned by experimenting with gases, watching now differences in temperature made them change.难点：作方式状语的现在分词短语watching...change 包含宾语从句how...change译文：最早研究热的学者用气体做实验，观察温差如何使气体发生变化而进行研究。

例 3For example, lectures are often televised, enabling students to hear and see the lecturer without all being crowded into a single lecture hall.难点：分词短语enabling...lecturer,同时又出现了介词短语without...hall译文：例如，经常用电视转播讲课，使学生们用不着挤在一间课堂里也能听到和看到老师讲课。

英语长难句分析他山之石 2009-09-11 13:08 阅读144 评论0字号: 大中小在阅读中，我们经常会遇到一些长而难的句子。

长难句通常含有较多、较长的修饰成分、并列成分或从句。

长难句的丰富内容和复杂结构往往会导致理解的困难。

理解长难句的关键是了解长难句的类型，理清句子成分，抓住句子中的关键部分。

一、长难句的分类1、带有较多成分的简单句。

如:Having chosen family television programs and women’s magazines，the toothpaste marketer，for instance，must select the exact television programs and stations as well as the specific women’s magazines to be used. 例如，决定选择家庭电视节目和妇女杂志后，牙膏经销商还必须挑选出要用的确切的电视节目和电视台，以及那些具体的妇女杂志。

在这个有30多个词的简单句中，动词-ing形式短语用作时间状语，不定式to be used修饰的不仅是w omen’s magazine，而且还修饰television programs and stations。

exacttelevision同时修饰programs和stations两个词，这在翻译中可以看出来。

插入语for instance把主语和谓语分隔开了。

2、含有多个简单句的并列句。

如:In the 1970s he was a surgeon at Yale，had a wonderful wife and five beautiful children，but he was terribly unhappy.在20世纪70年代，他在耶鲁当外科医生，有位出色的太太和5个漂亮的孩子，但他那时过得却很不开心。

在第二个并列句中，即在had前面省略了and he。

翻译一本通：难句解析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。

【英语长句难句】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 descendants an individual will have and hence the number of gene copies transmitted 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 individual will have中，an individual 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记录下一朵花的结构和文理的那种意义上的欲望。

高考英语阅读长难句分析方法与实例一、长句难句是如何产生的1、分支多，短语多英语句子主干是构成五种基本句型的基础：这五种结构之所以为基本结构，因为这五种结构是构成英语语句子的主干，英语长句都是通过这五种基本结构演变而来的，掌握句子五种基本结构是分析和理解英语句子的基础。

英语句子的特点是除了词可以做句子成分外，短语和句子都可以做句子成分。

就算是一个单句，如果都是以短语为句子成分，再加上句子如果分支较多的话，也可以构成比较复杂的句子。

2、分句多，从句多英语复合句可分为并列复合句与从属复合句。

并列复合句是在结构和意思上都可以相互独立的两个或多个单句构成的复合句；从属复合句是一个句子做另外一个句子的句子成分，两个句子不可以相互独立成为句子，如果两个句子拆分会导致句子意思不完整，或句子成分残缺。

在英语复合句中特别是从属复合句，从句中还可以有从句或其它并列句，有些复合既有并列句，又有从属句。

复合句也是构成英语长句难句的重要原因。

二、长句难句的分析方法长句难句的分析方法可以概括为：先主句再从句，先主干再分支。

先主句再从句就是对有从句的长句难句，先不看从句，先找出句子的主句并分析主句的句子主干，再分析从句；先主干再分枝就是先分析主句与从句的句子主干，再分析句子的分枝，句子的分支主要是指定语和状语。

三、长句难句分析实例实例1：Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography.本句是含有定语从句的复合句，根据先主句再从句的分析方法，我们先去掉从句（who had got to within 100 miles of the South Pole in 1908），把句子简化为：Shackleton, a onetime British merchant-navy officer started a business before his 1914 voyage to make money from movie and still photography.再根据先主干再分支，把句子分支(主语同位语a onetime British merchant-navy officer，时间状语before his 1914 voyage，目的状语to make money from movie and still photography)都去掉，进一步简化为：Shackleton started a business.那么这个句子的几层意思就很明确了①Shackleton何许人，a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908②做了什么事，Shackleton started a business③什么时间做的，其目的为何 before his 1914 voyage to make money from movie and still photography实例2：These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic, which brings with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.本句也是含有定语从句的复合句，根据先主句再从句的分析方法，先去掉从句（which brings with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.），再根据先主干再分支，把句子分支（offered by the modern French Republic过去分短语做定语）去掉简化为：These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle.那么这个句子表达了两层意思：①当地市民得在传统自给自足的狩猎生活与现在生活方式之间找平衡。

长难句突破【长难句的套路】插入语、同位语、分隔现象、各种从句或较长的非谓语动词短语1找谓语，找定语一般情况下，一个谓语形式的动词对应其动作的发出者(主语)，我们可以根据谓语动词的意义来确定其主语。

而且，如果一个句子中出现两个或两个以上的谓语形式的动词，则该句可以是并列句或复合句(并列谓语动词的情况除外)。

如：People feared that weakening a 21-year-old ban on the sale of ivory would encourage illegal hunting and hurt elephant populations.【句意】二十一年来，象牙交易一直被明令禁止，人们担心削弱这一禁令会助长非法捕猎，导致大象数量减少。

【分析】that引导宾语从句，从句中谓语动词是encourage和hurt，根据逻辑意义，可知encourage和hurt 的主语是动名词短语weakening a 21-year-old ban on the sale of ivory。

变式1：People feared that weakening a 21-year-old ban on the sale of ivory would encourage illegal hunting，which would lead to hurting elephant populations.[非限制性定语从句只用which不用that]变式2：People feared that weakening a 21-year-old ban on the sale of ivory would encourage illegal hunting，leading to hurting elephant populations.[分词作结果状语]2提主干，去枝叶一般情况下，一个句子中的主句所表达的信息为主要信息，从句、状语和定语等所表达的信息为次要信息。

英语长难句子及解析10例以下是10个英语长难句及其解析：1. "Having been informed of the situation, the president immediately convened a meeting to discuss possible solutions."解析：这是一个复杂的过去分词短语作为时间状语的句子。

句子的主语是"the president"，动词是"convened"，而过去分词短语"having been informed of the situation"修饰整个动作。

2. "Despite the heavy rain and strong winds, the athletes persevered and successfully completed the marathon."解析：这是一个含有并列连词"despite"的复合句。

主句是"the athletes persevered and successfully completed the marathon"，连词"despite"表示对比关系，引导一个状语从句"the heavy rain and strong winds"，描述了困难条件。

3. "Not only did she win the award, but she also set a new world record in the process."解析：这是一个包含倒装结构的并列句。

主句是"she won the award"，后面使用了倒装结构，形式为"not only + auxiliary verb + subject"，另一个并列成分是"she set a new worldrecord"。

英语长难句解析一、定语从句【难句】1. Even China’s population will be declining by the early 2030s, according to the UN, which projects that by 2050 populations will be lower than they are today in 50 countries. (The Economist Jun.5, 2006)【结构分析】本句结构清晰，是一个复合句。

主句为Even China’s population will be declining by the early 2030s, according to the UN，其后的定语从句which projects that by 2050 populations will be lower than they are today in 50 countries修饰先行词UN，关系代词在从句中作主语，注意这里project作动词用，译为“指出”，且从句里使用了比较级。

【参考译文】联合国有关报告指出，即便是中国，到2030年初期人口也将开始递减。

这份报告同时还指出，到2050年，将有50个国家的人口低于今天的水平。

【难句】2. That is surely how history will judge modern criticism of video games, which are accused of turning young people into violent criminals. (The Economist Jun.18, 2006)【结构分析】本句的主句That is surely how history will judge modern criticism of video games是主系表结构，其中表语由how引导的名词性从句充当，定语从句which are accused of turning young people into violent criminals修饰先行词video games，关系代词which指代先行词video games在从句中作主语，这里使用了被动语态be accused of，在翻译时我们译成主动。

外教一对一英语长难句分析1. Pumas are large, cat-like animals which are found in America.美洲狮是一种体形似猫的大动物，产于美洲。

这个句子比较简单：主系表结构;稍稍复杂的就是有一个定语从句而已。

2. When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.当伦敦动物园接到报告说，在伦敦以南45英里处发现一只美洲狮时，这些报告并没有受到重视。

第一层分析：这个句子主干其实就三个成分：时间状语(从句)，主语+谓语(被动语态)+方式状语。

第二层分析：但状语从句比较复杂：When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London,状语从句结构：when(引导词，不做成分)+主语+谓语+状语+同位语从句(作主语reports的同位语)第三层分析：这是一个同位语从句(名词性从句作同位语)that a wild puma had been spotted forty-five miles south of London从句的结构比较简单：that(引导词，不做成分)+主语+谓语+状语3. However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.可是，随着证据越来越多，动物园的专家们感到有必要进行一番调查，因为凡是声称见到过美洲狮的人们所描述的情况竟是出奇地相似。

考研英语长难句经典200 句解析1．Tight-lipped elders used to say, “It’s not what you want in this world, but what you get.”结构分析：本句的主干是elders used to say…。

直接引语中是主系表结构, 注意not…but 结构。

”2．You can make a mental blueprint of a desire as you would make a blueprint of a house, and each of us is continually making these blueprints in the general routine of everyday living.结构分析：这句话是and 连接的两个并列句。

在第一个分句中，as 是连词，引导比较状语从句，把a mental blueprint of a desire 和a blueprint of a house 相比较。

第二个分句中的主干结构是：each of us is…making blueprints…。

第二个分句中用一般进行时表示经常发生的事情。

这样的结构常常用来表达经常发生的令人不快的、令人讨厌的事情。

参考译文：你可以在脑子里为你的愿望画一幅蓝图，就象给房子画蓝图那样。

实际上，在日常生活中，我们每一个人都在不断地描绘着这些蓝图。

3 ．While talking to you, your could-be employer is deciding whether your education, your experience, and other qualifications will pay him to employ you and your “wares” and abilities must be displayed in an orderly and reasonably connected manner.结构分析：and 连接两个并列句。

11. To really develop empathy, you’d better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a“sharing circle”with your family, or spend time caring for pets at an animal shelter.【句式翻译】要真正开发同理心，你最好在养老院或医院做志愿者，加入一个有多样化的会员的俱乐部或团队，与你的家人有一个“共享圈”，或者在动物收容所照顾宠物。

【句式分析】本句是复合句，that引导一个非限制性定语从句，修饰先行词a club or a team，volunteer, join, have和spend是并列的谓语动词，To really develop…在句中作目的状语。

【词语点拨】volunteer v.志愿n.志愿者Some graduates volunteer to work in the countryside.一些大学生自愿到农村去。

She now helps in a local school as a volunteer three days a week.目前她在当地的一家学校做志愿工作，一周去3天。

【语法点拨】不定式to do可以作目的状语（其否定形式：not to do），相当于in order to do 和so as to do (so as to do只能放在句中，不能位于句首)。

如：One should get enough exercise to keep healthy.为了维持身体健康，一个人要有足够的锻炼。

To find a better job, a lot of people choose to go to the big cities.为了找份更好的工作，很多人愿意到大城市去。

1. The American economic system is, organized around a basically private-enterprise, market- oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most.[参考译⽂] 美国的经济是以基本的私有企业和市场导向经济为架构的，在这种经济中，消费者很⼤程度上通过在市场上为那些他们最想要的货品和服务付费来决定什么应该被制造出来。

2. Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, that together determine what shall be produced and how resources are used to produce it.[参考译⽂] 因此，在美国的经济体系中，个体消费者的需求与商⼈试图化其利润的欲望和个⼈想化其收⼊效⽤的欲望相结合，⼀起决定了什么应该被制造，以及资源如何被⽤来制造它们。

考研英语历年真题阅读长难句100句精析1. While warnings are often appropriate and necessary — the dangers of drug interactions,for example—and many are required by state or federal regulations,itisn't clear that they actually protect the manufacturers and sellers from liabilityif a customer is injured.【译文】尽管警告常常是适当而且必须的——比如对于药物相互作用的危险提出警告——许多警告还是按州或联邦政府规定要求给出的，然而(我们) 并不清楚，如果顾客受到伤害时，这些警告是不是确实可以使得生产者和销售者豁免责任。

【分析】在这个主从复合句中，it isn't clear that they actually protect themanufacturers and sellers from liability if a customer is injured是主句。

主句用了一个形式主语it，真正的主语是that引导的从句，而that从句之后是一个if引导的条件从句。

从句由两个部分组成，中间用and连接。

破折号之间的部分是举例说明warnings 的内容。

注意：many are required by state or federal regulations中的many是指many warnings。

2. Additional social stresses may a lso occur because of the population explosion or problems arising from mass migration movements—themselves made r elatively easy nowadays by modern means of transport .【译文】由于人口猛增或大量人口流动(现代交通工具使大量人口流动变得相对容易) 所引起的各种问题也会对社会造成新的压力。
