要做好语法填空题，理解短文是解题的前提，扎实的词汇、句型和语法知识是基础，英语国家背景知识是必要的补充。现以下题为例，谈谈语法填空题的解题思路。
阅读下面短文，根据上下文填入适当的词语，或用括号中的词语的适当形式填空：
A proverb says, “Time is money”. But in my opinion, time is even 1 precious than money. Why? 2 when money is spent, we can earn it back. However, when time is3, it will never return.
4 is known to all that the time we can use is limited. Therefore we should make 5 use of our time to study hard so as to serve our country in 6 future.
But it is a pity that there are a lot of people7 do not realize the value of time. They8their precious time smoking, drinking and playing.
In a word, we should form the good habit of9 (save) time. Do not put off what can be done today10 tomorrow.
1. 根据语法知识进行填充
第1题，由than可知，precious要用比较级，多音节形容词的比较级在前面加more，故此题答案为more。
第7题，因there are…是个句子，do not…应是一个定语从句，缺主语，先行词是人，应填who。
2. 根据逻辑关系进行填充
就是根据上下文的逻辑关系来解题。
第2题，因前句用Why提问，应当用Because往返答，故此题答案是Because。
3. 根据语篇标志进行填充
语篇是指比单个句子长的语言单位（句群、段落、篇章等）。语篇间往往有标明内在联系的词，我们称这些词为“语篇标志词”。如表示结构层次的有first, second, third, finally等；表示逻辑关系的有thus，therefore，so等；表示转折关系或变换话题的有however, but, by the way等。“语篇标志词”对迅速理清文章的脉络，弄清上下文关系很有帮助。
