语法填空的解题技巧

语法填空是通过语篇在语境中考查语法知识的运用能力。我们在解题前应快速浏览短文掌握大意，有把握的空格可以进行填写。在读懂的基础上，再结合短文提供的特定的语言环境去逐句分析逐题解答。按题型设计分三种情况：

1. 纯空格试题的解题技巧

首先分析句子结构，根据所缺成分确定哪类词。然后，根据句子意思，确定具体填什么词，或根据两句间的逻辑关系确定具体用哪个连词。此处考查的冠词a的填写。

2. 给出了动词的试题解题技巧

首先，判断要填的动词是谓语动词还是非谓语动词。若句子没有别的谓语动词或者虽然已有谓语动词，但需填的动词与之是并列关系，所给动词就是谓语动词，若是谓语动词就要考虑时态和语态；若句子有谓语动词则用非谓语动词（动词不定式、现在分词、动名词和过去分词）。

3. 词汇转换题解题技巧

这类题主要考查名词、形容词和副词。根据该词在句中所做句子成分确定用哪种形式。
