2013年成人英语三级完形填空练习及答案解析
【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，终确定个别难题。
