外语教育网的小编整理了成人英语三级专项备考之说明文类完型填空，希望能够对大家的复习有所帮助。

【题型点津】 完形填空解题策略

1、浏览全文，了解大意。首先利用首句，跳过空格，浏览全文，从整体上感知全文，了解文章大意以及故事发展情节，然后再进行试填。由于学位英语完形填空的答案提示信息大多在后文出现，所以切忌看一句填一句。

2、瞻前顾后，先易后难。了解文章大意后，结合各选项的意义和用法，从易到难，先做更有把握的题目。对于少数难题，暂时跳过，结合上下文，仔细推敲后便会迎刃而解。

3、复读全文，查漏补缺。答完全部题目后，要结合自己选择的答案再次阅读短文，围绕文章中心，查看文章内容是否通顺、结构是否完整、搭配是否有误，是否断章取义等。根据短文中句与句，段与段的逻辑关系进行判断，更终确定个别难题。
