1、关于高考英语技巧长难句分析第1页，此课件共87页哦前言n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打断和干扰考生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。第2页，此课件共87页哦一、复合从句 n这些句子往往较长，一个从句套着另一个从句，环环相扣，使得考生搞不清楚整个句子结构。其实，不管句子有多长有多复杂，它只由两部分构成，即主干和修饰成分主干和修饰成分。主干是整个句子的骨架，主要指主谓宾结构(如:I

2、 want a ticket.)或主系表结构(如:The man is a teacher.)。而修饰成分在句中只起修饰或补充主干的作用，它既可以是单词，也可以是短语，更常见的则是从句，尤其是定语从句和状语从句。n第3页，此课件共87页哦一、复合从句n这些从句都很常见，考生比较熟悉，但很多时候不少考生分不清单词、短语和从句之间的相互关系，这样会导致整个句子分析混乱。这时，考生应通过仔细分析，将每个修饰成分划出来，找出句子的主干，这样整个句子结构就清晰了。第4页，此课件共87页哦二、分隔结构n为了调整语气和增加补充信息，更主要的是为了平衡句子结构，避免头重脚轻，使语义严密，结构紧凑，可将语法关系

4、高，考生需要熟记。第6页，此课件共87页哦四、改变语序n改变语序主要指倒装句式倒装句式。这种打破相对固定的常规语序的做法，或是为了强调句子的意义表达的重心，或是强调一种表达语气，如虚拟语气、否定语气等。这些句子往往和一些副词、连词相关，有明显的标志。n当然，被动句、双重否定句等句式在阅读考试中也屡屡出现，限于篇幅本文未将其归入。希望考生能结合阅读实践来体会上述句法特征。第7页，此课件共87页哦突破策略 (1)结构分析法n所谓结构分析法，就是通过语法分析，迅速弄清句子的结构，把握住句子的基本框架。n基本步骤是：首先，首先，判断该句是简单句、并列句还是复合句；然后，找出句子的核心成分，分清主语和谓
