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.
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.
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。
(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.
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）。
2. There __________some bread on the table.
3. ________there any maps on the wall

4. There __________twenty desks in our classroom.
5. ________there a cup of tea on the table
