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.
