《There be 句型》微课教学设计 学校：口镇中心小学 设计者： 时间： 知识点名称There be 句型 学科类型及其对象语法 小学英语四年级下册 微课基本信 息 上课时间长度10 分钟 教学资源 与环境 PPT 教学目标 1、讲授 There be 句型的定义及结构 2、正确使用 There be 句型的肯定，否定及一般疑问形式 教学过程 Today we’ll learn “there be”. 一：There be 句型的定义及结构 1、定义：There be 句型表示某地有某物或某人 2、结构：一共分为三种 (1) There is +单数可数名词+ 地点状语. There is a book on the desk. There is an umbrella in the bag. (2) There is +不可数名词+ 地点状语. There is some milk in the cup. There is some sheep and a cow on the farm. (3) There are +复数名词+地点状语. There are four chairs in the living room. There are some birds and a balloon in the sky. 从以上例句中我们可以发现 there 是引导词，在句中不充当任何成 分，翻译时也不必译出。

句子的主语是某人或某物，be 动词表示 “有”，谓语动词 be 要与主语（某人或某物）的单复数保持一致 Some 既可用于可数名词也可用于不可数名词 二：There be 句型的变化 1：变成否定句 There be+not+某物+地点状语 There be 句型的否定式的构成和含有 be 动词的其它句型一样，在 be 后加上 not. 注意，is not 的缩写是 isn’t，are not 的缩写是 aren’t. 当肯定句中有 some 时，要将其改为 any（疑问变化也一样） There isn’t a book on the desk. There isn’t an umbrella in the bag. There isn’t any milk in the cup. There isn’t any sheep and a cow on the farm. There aren’t four chairs in the living room. There aren’t a lot of birds and a balloon in the sky. 2：变成一般疑问句 ,. There be 句型的一般疑问句变化是把 be 动词调整到句首，再在句 尾加上问号即可。
