微课说明文档我录制的是模块七第二单元的语法系动词的用法：首先，找好需要讲解的内容，然后制作成 PPT。第二步，下载安装录制微课的 Camtasia Studio 软件第三部，找一个安静的地方，装好耳机后开始录制 PPT，边播放边讲解第四部，录完后按照提示完成生成制作就可以咯。以下是我录制的内容：What’s a linking verb?• 系动词，亦称连系动词（Linking Verbs）。作为系动词，它本身有词义，但不能单独用作谓语，后边必须跟表语，构成系表结构. 说明主语的状况、性质、特征等情况。• 分类: 状态系动词; 持续系动词; 表像系动词 感官系动词; 变化系动词; 终止系动词 状态类系动词：用来表示主语性质或状态，只有 be 一词• He is a teacher. •I am ill.
