《There be句型》微课教学设计学校：口镇中心小学                           设计者：            时间：微课基本信息知识点名称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。
