①跳过空格、通读短文、了解大意

解题时先跳过空格，通读初二英语完形填空的短文，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。
