高中英语长难句分析（附历年高考长难句100例）阅读理解得分低，往往是因为文章看不懂，文章中的句子之所以难以理解，有许多原因，其中一个主要原因是句子太长或者句子结构复杂。
句子过长或者复杂通常是该句除了主干之外还包含了一些附加部分，如插入语、同位语、分隔现象、各种从句或较长的非谓语动词短语等等。
下面我们来谈谈几种英语阅读长难句的处理方法。
如何处理长难句？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，则该句可能是并列句或复合句(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。
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。
若句子的主干提炼不出来，就不能完全把握句子的核心意义，从而导致思维混乱，主次不分。
如：Economists from the University of Sussex analysed findings from the National Longitudinal Study of Adolescent Health, a 15-year research project charting the fortunes of a group of thousands of teenagers who attended high schools in the US in the mid-1990s.【句意】来自萨塞克斯大学的经济学家们分析了国家青少年健康纵向研究的研究结果，这项研究是一个历时15年的课题，它记录了数千名在美国20世纪90年代中期上中学的一组青少年的财产情况。
