“语法填空”从样题的命题形式来看，“语法填空”题仍属于国外一直使用的一种完形填空题，在国内的传统练习和测试中也很常见。一般认为，这种不提供选择项的“语法填空”题比这些年来高考采用的提供选择项的完形填空题的难度略大。但也有人认为，这种无选择项“语法填空”题由于没有干扰项反倒有利于考生更好地发挥其英语水平。
解“语法填空”题的一般步骤是：
一、浏览全文 把握语篇
浏览全文的目的是把握其大意，为下一步“填空”做好“语义”上的准备，因为“语义”决定着空白处应填一个什么意思的词语并采用什么样的语法形式。在通读全文的过程中，为较好地把握其大意，很有必要弄清该文的体裁、题材（语题）、中心思想、写作主线、段落大意、段落层次等。这些有利于考生真正读懂全文大意，也有利于在“填空”时进行必要的逻辑推理。
二、边读边填 先易后难
在通读全文，基本了解文章大意之后，就可以动手填空了。填空的过程是一个判断空白处应填词语的“语义”（已给出词语的除外）和正确的语法“形式”的思维过程。遇到一时想不起来的空，先跳过去，等检查时再仔细对付，不要用太多的时间停留在一个单词上。
三、验证复查 清除难点
有时间的话，进行复查是必要的。复查的方法是：将所有答案“填进”短文并进行通读，以最后确定答案。
另外，一题多解也是此种题型常遇到的问题之一。
