高考英语二轮复习与增分策略 专题三 完形填空 第二节 方法运用于命题

第二节方法运用于命题完形填空的常考命题1记叙文记叙文主要是记人、叙事、写景、状物一类的文章，具体地说，它是借助叙述、描写、抒情等手段记叙社会生活中的人、事、景、物的状态及其发展过程，用以表现作者的思想，抒发某种情感的文章形式。近年来高考记叙文主要以叙事、记人为主，解答记叙文体的完形填空时，应着重把握以下几点：(1)抓住文章中心思想。中心思想是文章的灵魂和统帅，其他的写作要素都紧紧围绕这一中心进行。(2)明确叙述角度。记叙文通常有两大叙述角度：第一和第三人称。第一人称就是从“自我参与”的角度进行叙述；第三人称就是从“旁观者”的角度客观地记人、叙事、状物。(3)理清写作顺序。根据写作的需要作者往往采用顺叙、倒叙或插叙等方法。(4)明确写作要素。包括事件、人物、时间、地点、原因和结果等。 (5)洞悉写作目的。只有心中有了目的，在情节选择和细节描写上才会作出合理的安排。明晰了写作目的，就能抓住文章的主题。2夹叙夹议文该类题目的特点是：作者先叙述一个事件，然后提出自己的见解或揭示蕴含的哲理，或是作者边叙述边议论，揭示社会现象等。文章的显著特点是首句可能在传达一个事件信息或透视一种社会现象，而后对此进行高层次评价，或由此引发一种深层次思考，具有记叙与议论的双重性，文情并茂，发人深思。解题时，应借助上下文乃至全文的语境揣摩作者的心境，及其对各个角色、各个事件的态度。在答题过程中，要理清文章的脉络与结构，把作者叙述的故事和要表达的观点结合起来分析，并且要把握好关联词语，还要把握语气、动作等细节的描写，从而与作者达到共鸣。3议论文议论文通过剖析事物来论述道理、提出主张、发表见解等。这种文体一般由三个要素组成：论点、论据、论证。要做好议论文类的完形填空最重要的是抓住作者的论点。不同的议论文论点的提出方式往往不同，大体有以下三种情况：(1)开门见山式。提出论点引用具体的论据总结全文。(2)导入式。叙述生活中的一件具体的事情或描述生活中的现象针对问题，提出论点用论据说明论点。(3)结尾式。列举生活现象分析具体现象得出结论。对于纯议论形式的完形填空，要在掌握全文主旨的情况下，抓好每段的主旨句。抓住了每段的主旨句也就把握了文章的脉络，理解文章就容易了。4说明文说明文一般语言简练，按照一定的规律介绍事物的类别、性质、特点、构造、成因、关系等。常见的说明文有人物介绍、产品说明、解说词、实验报告、习俗介绍、节日介绍等。说明文的文章多用现在时态，语言平实、准确；常采用客观描述；文章主题明确，层次分明。在解答说明类完形填空时注意下面的解题技巧：(1)明确说明对象，理清段落联系：通读全文，明确作者是针对哪一个说明对象从不同的角度和侧面对其加以说明的。在阅读过程中要概括、总结每一段说明的侧重点，理清各段之间的逻辑联系，加深对说明对象的理解。(2)弄清说明顺序，把握作者态度：在说明的过程中作者会选择合理的说明顺序对说明对象进行有条不紊的解说。把握了说明顺序，就能准确把握文章的脉络，加深对整篇文章的理解。常见的说明顺序有时间顺序、空间顺序、逻辑顺序(如因果关系、先主后次等)和认识顺序(如由此及彼、由浅入深、由局部到整体、由现象到本质、由具体到抽象等)。另外，在理清作者思路的基础上，还要注意反映作者态度的关键词或关键句，把握作者的写作情感和意思。点津无论哪个体裁的文章，考生都应先通读全文、掌握大意，然后多种解题方法并用，即往往是多种方法解一种题，而不是一种方法对应一种题。记叙文(2017全国)In
