100个考研真题中的长难句总结
100个真题中的长难句总结1. Such large, impersonal manipulation of capital and industry greatly increased the numbers and importance of shareholders as a class , an element in national life representing irresponsible wealth detached from the land and the duties of the landowners; and almost equally detached from the responsible management of business.[句子主干]Such large, impersonal manipulation of capital and industry greatly increased …shareholders as a class, (which was) an element…[语法难点]本句是典型的非限定性定语从句，难点在其主语和宾语都有较长的短语和of结构限定，并且分句是由两个and相连的3个部分组成的。
分句an element…landowners 又带有两个定语从句，一个是（which was）representing… ，另一个是(which was)detached…。
可见，定语从句的难点在于经常省略“引导词+be”的结构，从而在理解上容易和分词结构相混淆。
[句子翻译] 对资本和企业的这种大规模的非个人操纵大大增加了股东作为一个阶级的数量和重要性。
这个阶层作为国计民生的一部分，代表了非个人责任的财富与土地及土地所有者应尽义务的分离，而且也几乎与责任管理相分离。
[翻译技巧] 实际上定语从句并不符合汉语的使用习惯。
所以翻译时遇上定语从句，一定不要机械地按照原来的顺序生搬硬套。

新航道考研英语长难句100句解析(经典)
长难句是英语考试中必考的容，许多同学之所以英语成绩不高，正是因为阅读习惯和思维方式受到句子长度和难度的干扰，这也是出题者的意图所在。
下面给大家介绍几种常见的英语长难句，方便大家复习。
1.含有分隔结构的句子分隔结构在英语表达中经常出现，它的作用主要是调整语气、补充信息以及平衡句子结构。
在阅读长难句中出现较多的分隔形式是插入语。
插入语有很多不同的类型，可以是一个词，比如形容词(strange，etc)、副词(personally，honestly，fortunately，luckily，etc)；可以是短语，比如形容词短语(worst still，sure enough，etc)、介词短语(of course，in short，as a matter of fact，by the way，etc)、分词短语、动词不定式(to be sure，to tell you the truth， etc)；也可以是句子，比如if I may say so，if you don't mind，that is(to say)等都是非常常见的插入语。
通常，去掉句中这些插入成分不会影响句子的完整性。
如：I say /hear，I think /hope / believe，you know / see，what's more，I'm afraid，do you think / suppose等。
如：His journey to the hell began innocently enough when, as chairman of Computer Associates International，a software company，he first heard how quickly his employees had accepted their new electronic-mail system. 这是一个典型的含有多个插入语的长句。
