5、、分析判断能力、逻辑推理能力和跨文化交际能力。2.体裁分析。近三年高考完形填空的体裁主要以记叙文为主,叙中有议,文章情节完整,语言地道纯正,体现了“跨文化意识”,篇章与语句的结构富有变化,常涉及人物心理活动的细致描写,启迪性强。近几年,高考完形填空的体裁已突破了单一的叙述文体,间或有说明文和议论文出现。这就要求学生在备考中,在关注记叙文练习的同时,也应时常涉猎其他文体的训练。3.话题分析。近四年高考完形填空的话题新颖、时尚,把知识、教育、趣味融为一体,内容贴近学生的学习和实际生活,反映社会现实,体现人文精神,符合高中生的兴趣爱好和认知特点。在备考中,精神信念、人格尊严、生活心态、人间真情、科技

6、进步、人生感悟、合作、赏识、责任等话题仍需关注。4.考点分析。高考完形填空设空以单词填空为主,短语或词组填空为辅;考查以实词为主,虚词为辅。高考完形填空题的命题将继续坚持“考查语境,突出语篇,注重实词”的命题原则,继续加大对实词意义辨析的考查力度,并突出考查考生的分析判断能力、连贯性思维能力和对语境的把握能力。二、完形填空方法指导1.细读首句,预测主题第一句往往是所读文章的主题句。它是文章的窗口,通过它可以大致了解短文与作者的意图。所以细读首句、重视首句、正确理解首句是解题的关键,是正确预测主题的基础。要细心阅读,客观分析,理性思考,以便挖掘出更多有用的潜在信息,为解题打下坚实的基础。2.速读

7、全文,领会大意在这一步要运用跳读技巧。借助首句所给的启示,跳过空格,快速把全文从头到尾通读一遍。力争捕捉文中有用的关键信息,从而了解文章的体裁、背景、内容、结构、情节发展、前因后果、论点论据等,进一步从整体上理解所读文章的大意。同时对空格所选答案进行估计,即试探性的猜测。切忌看一句,选一空。3.细读全文,试填答案根据大意,以全文为背景,以上下文为依托,选取语法上正确、文意贴近的答案填入,初步完成空格上的内容。试填选项时,一定要注意在语境上下功夫,一定要抓住上下文的内容内在的联系和逻辑关系,进行多角度、全方位地分析。在通读时要复读上一句,兼顾着下一句,即“瞻前顾后”。在阅读时不要忽视连接词、代词

8、、插入语、转折语等的作用。因为这些词往往是改变语境的关键词,它们具有因果、让步、递进、转折、指代、列举、承上启下的特殊功能。4.完形完义,立足全局做完形填空有两个程序:一是完形(选择选项,然后填补空白);二是完义(阅读短文,然后理解短文)。但是完形必须在完义的基础上进行,也就是说首先要在阅读理解短文的基础上做好完形。完形必须服从完义,单句必须服从段落,段落必须服从全文,局部必须服从全局。因此,我们在做完形填空题时,不能读一句做一句,更不能看到就填,这样往往要出差错。先从整体到局部完义,再从局部到整体完形,完形完义,立足全局。5.复读全文,验证答案题目做完以后,我们要把“完形”后的全文再读一遍,

9、看看是否“完义”,检查自己对全文的理解是否准确,情节发展是否合理,全文前后上下是否符合逻辑,验证自己完形后的答案是否能使全文贯通流畅,如果读起来流畅而通顺,说明既完形又完义。总之,我们要从完形和完义、语法和语义等方面进行推敲,修正错误,弥补疏漏,从而使自己的答案尽可能地接近或达到完美。拓展阅读Planetary changes which will have an influence on many are drawing near because of the poor ecological1 state of the planet.Actually change has already b
