第02讲 完形填空专题完形填空对考生在语篇中准确理解和灵活运用词汇的能力的考查尤为突出,主要涉及名词、(短语)动词、形容词和副词的词义理解、一词多义的积累、以及熟词生义的判断。
完形填空的解题过程中,除了需要具备扎实的语言知识之外,还需要一套过硬的解题方法和技巧,很明显,如果掌握了正确的解题思路,就会起到事半功倍的效果,从而大幅度提高正确率。
1. 读透首句,掌握主旨重视首句,明确短文话题,了解篇章结构,预测全文内容。
绝大多数记叙文的作者都会用一句话点明人物的姓名、身份或事件发生的时间、地点,然后再逐渐深入介绍事件的发生、发展,最后得出结论,所以读透句首对学生了解全文至关重要,这就是我们理解文章内在联系的"突破口"。
2. 跳空速读全文,掌握中心速读全文要求一气呵成,跳过空格,快速阅读,领会大意,把握中心。
重点了解记叙文的要素,如:时间、地点、人物和事件等,从整体上把握文章的叙述顺序和结构主线。
3. 身临其境,故事重构采取换位思考的方式,假设自己就是故事的主人公,在此情此景下,模拟故事的情景,体会人物的心情,推理故事的发展,体验作者的心情以及观点和态度等,这样才能对故事或事件有一个贴切的把握,才能选出符合语境的选项。
同时要注意文化背景知识和生活常识。
4. 关注末段,注意感想最后一段通常是作者的有感而发、心理体验或经验教训等。
要注意结合语境选用合适的形容词、副词、内容要求完形填空 1. 句内层次理解2. 句际层次理解3. 语篇层次理解知识讲解学习目标动词或名词等。
5. 浏览全文,复查核定根据记叙文的线索,考生一定要进行回查,仔细推敲,校正全文,使故事恢复原貌。
检查要点是:(1)语意是否前后一致;(2)上下文是否通顺连贯,内容是否完整;(3)所选词汇是否符合语法、句法结构;(4)文化背景和生活常识是否合理。
