比较级最高级基础学案

形容词-副词的比较基础教学案

教学重点教学难点教学过程：adj 、adv 的比较级：比较级的倍数表达法

用于两者（人或物）之间，表示“其中一个比另一个更⋯⋯”或“较⋯⋯”，后面通常用连词than 连结另一个比较的对象，其基本句型是：

主语＋谓语（系动词）＋形容词比较级＋than ＋对比对象。

ex. Jim is than Mike. （tall ）

Mike is than Jim. （short）

It ' s today than it was yesterday. （hot）

形容词、副词比较级和最高级的构成

1. 形容词比较等级的规则变化：

2.部分形容词的比较等级变化时不规则的：
