30、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150200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

31、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。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
