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.
