1、第二篇知识运用攻略专题三完形填空第一部分 解题技法总论【考情透析】1.选材体现新课标理念文章的选材注重原汁原味,内容体现了新课标的“关注学生情感,提高人文素养”这一理念,对环境保护、心理问题、校园生活、奇闻趣事等热点话题继续关注。2.题目难度有所上升文章体裁以记叙文(夹叙夹议文)和说明文为主。文章的长度在250词左右,首句不设空。设空的密度相对稳定,平均每14词挖一个空格,通常不会出现两个空格前后相连或同一句子挖空超过三个的情况。试题设置注重“低头翘尾”,第一空难度较低,有助于考生融入语境,但后半段逐渐升华全文主题,难度往往较大。3.强调学生的综合阅读能力文章注重考查学生对语篇的理解,而单纯对

2、词语搭配和语法知识的考查极少。考生在解题时,要站在语篇的角度,结合对上下文的理解,通过具体的语言环境来做出选择,一定要注意“上下联系”和“前思后想”。4.考查重点明晰完形填空多重视考查语言的内容,与承载具体信息的实词紧密相关,所以设空以考查实词为主,包括动词、名词、形容词和副词等,对冠词、连词和介词等虚词考查较少。【策略点睛】解完形填空题的4个步骤 步骤1.细读首句,预测主题 完形填空所选短文首句通常不设空格,因此它往往是了解文章全貌的“窗口”;根据首句可判断文章体裁,推测文章大意,对理解全文有重要的启示作用。步骤2.通览全文,掌握大意 做完形填空时考生应根据首句给予的提示,借助文中的关键词,

3、全面理解全文大意。快速通读全文,理清脉络,抓住主线,做到全局在握是正确解答完形填空题的首要前提。步骤3.瞻前顾后,先易后难(1)瞻前顾后,不要忘记首尾照应。在注意到首句重要性的同时,也不要忽视尾句画龙点睛的作用。要牢记文章的中心思想,每个空格处的含义与前后句的意思要联系起来理解。文章最前面的空格提出的问题很有可能要到文章的末尾才能找到答案。(2)先易后难,就是首先选出那些只根据上下文就能确定的、直接的、明显的答案,诸如固定词组、常见句型等。这就增强了信心,减轻了心理压力,以便集中精力解决难度较大的选项。步骤4.复核验证,敲定答案 填空全部完成后,还要通读一遍,根据文章的中心思想以及各段落之间、

4、前后句之间的内在逻辑关系,检查文章的整体;也可以从语法、词义、习惯用法、固定搭配、背景知识等方面进一步验证和修改答案。一、设空特点细识别,有的放矢稳拿分二、精通五种答题技巧,有效提高解题效率三、科学思维早养成,考场实战得高分(2019全国卷)The small town of Rjukan in Norway is situated between several mountains and does not get direct sunlight from late September to mid-March1six months out of the year.“Of course,we
