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。 基本句型：be + there+某物+地点状语？ 回答：yes, there + be. no, there + be +not. - is there a book on the desk? -yes,there is. - is there an umbrella in the bag? -no,there isn’t. - is there any milk in the cup? -yes,there is. - is there any sheep and a cow on the farm?- no,there isn’t. -are there four chairs in the living room? -yes,there are. - are there a lot of birds and a balloon in the sky?- no,there aren’t.
