语法填空学案一、考查语法
每一个空格的设置都必定涉及到某一条或某几条语法规则，不会单纯考查单词的拼写和词组的用法
例 1 In Greece, women had l ittle freedom
Wealthy women hardly left their houses, but they______ (allow) to attend weddings and some festivals例 2 The ______ why I was sad was that he didn't understand me
二、考虑语境
既然采用短文的形式来考查语法，其目的就是要利用短文有较强语境的特点来命题，否则，就不如用单句来考查语法了
也就是说，考生要填出正确答案，至少需理解整个句子的意思或各分句之间的逻辑关系，或者需要理解前后几个句子，甚至整个段落或篇章
例 3 Several changes have brought wild animals to the
Foremost, air and water quality in many cities have improved as a res ult of the 1970's pollution control efforts…三、考点分散
基本上一个空格代表一个语法点，10 个空有可能涉及到 10 个语法点，至少也得有 7 个语法点
笔者认为，即使对一些非常重要的语法项目，如动词时态、非谓语动词、不定代词等，单独一项也可能是一空，至多两空，设三空的可能性是极小的
四、适当提示
但是若涉及到动词的时态、语态、非谓语动词、词类转换等需要词形变化的空格
例 4 Oil prices have risen by 32 percent since the start of the year, _____
