高考英语阅读长难句分析
纵观历年高考英语试题，可以发现阅读文章中出现了许多结构复杂的句子。不难理解，
命题者在句子难度上大做文章，无非是想通过增加句子长度和使用复杂结构来打断和干扰考
生正常的阅读习惯和思维方式，从而达到考查考生综合阅读能力的目的。下面我们来了解长
难句最常见的形式。
1、带有较多成分的简单句。如：
，the toothpaste marketer，Having chosen family television programs and women’s magazines
for instance，must select the exact television programs and stations as well as the specific women 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，______________短语用作时间状语，不定式to be used 修饰的不仅是_______________，而且还修饰__________________________. exact television 同时修饰______________和______________两个词，这在翻译中可以看出来。插入语
____________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_______ ________.
Discrimination(歧视) isn’t their only concern；almost everyone testing positive for the gene(基因) develops symptoms(症状) during middle age，and doctors can do Huntington’s
nothing to help.
担心受到歧视并不是他们唯一的忧虑，几乎所有遗传性亨廷顿病基因检测呈阳性的人
在中年时症状都会显现出来，而医生对此却无能为力。
三个分句均为简单句，分别用分号和and连接。其中，第二个句子中的分词短语testing positive for the Huntington’s gene
是做everyone的___________;
3、含有多个从句的复合句。如：
ows and we use more and
I can’t live in fear of the possibility that as the earth’s population gr more of our nonrenewable(不能再生的) resources，our children may have to lead poorer lives.
我不能总是生活在对这种可能性的忧虑中：由于地球上人口的不断增长，由于我们正在
消耗掉越来越多的非再生资源，我们的孩子可能不得不过着更加贫穷的生活。

高考英语阅读理解中的长难句3
如何克服高考英语阅读理解中的长难句障碍-A 高考英语阅读理解题所选短文均选自英语原版文章，原汁原昧”，考生普遍感觉较难理解。那么，这些阅读材料到底难在哪儿呢除了生词量大、篇幅长、信息量大以外．就是短文中的句子结构较为复杂，搀杂了大量的长、难句。句法掌握不好的考生很难理清头绪，影响其对短文内容的理解。 1 When a woman's closest female friend might be the first to tell her to leave a failing marriage，it was n’t unusual to hear a tan say he didn’t know his friend’s marriage was in serous trouble until he appeared one night asking if he could sleep on the sofa． 2 He found out that Kit Williams had spent his childhood near Ampthill，in Bedfordshire，and thought that he must have tried the hare in a place he knew well，but he still could not see the connection with Katherine of Aragon, until one day he came across two stone crosses in Ampthill Park and learnt that they had been built in her honor in 1773． 一、抓住结构引导词分析其长难句结构和功能 任何一个复杂长句都不外乎由一个或多个并列结构和复合句构成。并列结构一般有连词and，but，or等连接；复合句按其在句中的作用可分为名词性从句、形容词性从句(定语从句)和副词性从句(状语从句)三大类。任何一个复合句都有一个至几个反应逻辑、意义及结构关系的引导词，找出这些引导词就能分析出复合句的完整句子结构，清理出完整意义。平时要注意积累表示各种逻辑关系的连词和短语。表示目的： 《 so that，for the purpose that，in order that等；表示结果：so…that…，such…that…，as a result，therefore，thus等；表示条件：if，on condition that，unless等；表示原因：because，since，as等。 【例l】Another good thing about the use of noise-killing systems is that it saves the need for a silencer, which not only reduces the weight of a car, but also makes the motor burn less oil and work better．(NMETl995 C篇) 析：这是一个含有that引导的表语从句的复合句。并且表语从句后接了which 引导的非限制性定语从句。非限制性定语从句内有not only…but also…连接的并列结构。句意：噪音消除系统应用的另一好处就是没有必要使用消声器．这不仅减轻了轿车的重量。而且使发动机耗油更少，运转更好。 【例2】We even have different words for some tools, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked, which shows the fact that the Saxon peasants were doing the farming，while he upper-class Normans were doing most of the eating．(NMET2001D篇) 析：whether…or…表示判断选择的搭配结构，which 引出定语从句，指代前文中的事实，that引出同位语从句，while引出状语从旬，表示对比。句意：我们甚至用不同的词语来表示食物，特别是肉类，取决于它们是否还在田问里，还是即将就厨。这表明撒可逊农民干的是农活而上层的诺曼人干的是吃喝。 【例3】A Swedish Kennel Club official explains what this means: if your dog runs out on the road and gets hit by a passing car，as the owner，you have to pay for any damage done to the car，even if your dog has been killed in the accident．(NMETl997 C篇)

高中英语阅读英语长难句分析方法
高中英语阅读英语长难句分析方法 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women’s magazine，而且还修饰television programs and stations. exact television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. Discrimination(歧视) isn’t their only concern；almost everyone testing positive for the Huntington’s gene(基因) develops symptoms(症状) during middle age， and doctors can do nothing to help. 担心受到歧视并不是他们唯一的忧虑，几乎所有遗传性亨廷顿病基因检测呈阳性的人在中年时症状都会显现出来，而医生对此却无能为力。 三个分句均为简单句，分别用分号和and连接。 3、含有多个从句的复合句。如： I can’t live in fear of the possibility that as the earth’s population grows and we use more and more of our nonrenewable(不能再生的) resources，our
