二. 完形填空特点及解题思路
（一）题型分类与特点
完形填空试题是在给出的一篇短文中有目的地拿掉若干个词,留下一些空格,要求考生借助短文保留的部分,从所给的短文整体出发,在正确理解短文意思的基础上,根据句子和句子间的内在联系、词的用法和习惯搭配等,用适当的词或词语填空,使补全后的短文意思通顺、前后连贯、结构完整.这种题型测试的内容从形式上看是单词或短语的填空,但它必须注意到短文中上、下文意思连贯、词语搭配和语法结构正确,所以在空格上所填的词必须符合语义适用和语法正确两条原则,只考虑某一侧面都可能导致错误.中考中完形填空试题的基本题型分两类：完形填空选择题和完形填空题.
1. 完形填空选择题：该题型的特点是将一篇短文中若干词语抽掉留下空格,对每一空格提供若干个选择项,要求考生通读短文后,在理解短文意思的基础上,运用所学的词汇、句型、语法等语言知识,从所提供的备选项中选出一个最佳答案,使短文内容完整正确.中考完形填空主要以这种题型为主.它所给的短文一般与初中英语教材难易程度相当,字数在150－200个单词之内,多数设置10个左右空格,所设考点涉及词汇、语法及对短文内容的理解.短文的第一句一般不设空,以期提供一个语境,对每一空格设置的选项基本都属于相同或对等的词类,给判定选择带来一定的干扰,侧重考查了考生准确运用词汇的能力及对短文的整体理解和逻辑推理能力.
2. 选词填空题：该题型的特点是把抽出的词打乱顺序,不按原文顺序排列,放在短文前面或后面的方框内,有时还增加几个文外的词,要求考生从中选出适当的词以正确的形式填入短文空格内.
（A）

完形填空选择题的一般解题思路是：
1. 跳过空格、通读全文、把握大意.先跳过空格,通读试题所给的要完形填空的短文,获得整体印象,做到弄清文脉、抓住主旨,较好地把握短文大意.要在阅读理解短文意思的基础上才开始判定选择,切忌仓促下笔.
2. 结合选项、综合考虑、初定答案.在理解全文意思的基础上,再结合所给备选项细读全文,联系上、下文内容,注意从上、下文的语法结构和词语搭配及从选择项中寻找解题的提示,以词、句的意义为先,再从分析句子结构入手,根据短文意思、语法规则、词语固定搭配等进行综合考虑,对备选项逐一进行分析、比较和筛选,排除干扰项、初步选定答案.
3. 瞻前顾后、先易后难、各个击破.动笔时要瞻前顾后、通篇考虑、先易后难.对比较明显直接的、自己最有把握的答案先做,一下子不能确定答案的,先跳过这一空格,继续往下做,最后回过头来再集中精力解决难点.这时可结合已确定答案的选项再读一遍短文,随着对短文理解的深入,可以降低试题的难度,提高选择的正确率.
4. 复读全文、逐空验证、弥补疏漏.完成各道题选择后,把所选的答案代入原文,再把全文通读一篇,逐空认真复查.看所选定的答案是否使短文意思前后连贯、顺理成章,语法结构是否正确,是否符合习惯表达法.如发现错误答案或有疑问的,应再次推敲、反复斟酌、做出修正.
完形填空试题的一般解题思路是：
1. 跳过空格、通读短文、了解大意.解题时先跳过空格,通读完形填空的短文,了解全篇的内容和要旨.要重视首句,善于以首句的时态、语气为立足点,理清文脉,推测全文主题及大意.
2. 复读短文、确定语义、判断词形.把握短文大意后再认真复读短文,利用上下文的语境,结合所学过的知识,先确定空格处所需词语的意义,再根据空格在句子中的位置,判断其在句中充当的成分,从而确定所填词的词性,再依据词语搭配和语法规则,判断所填的词的正确形式.
3. 三读短文、上下参照、验证答案.在短文的每一空白处填上一个词后,将完成的短文再细读一遍,上下参照,连贯思考.把所填的答案放入短文中进行检验,可从上、下文内容是否协调一致、顺理成章,语法结构是否正确无误等进行综合验证,凡有疑问必须重新推敲考虑.
