教学重there be 句型的肯定式、否定式一般疑问句及其回答方式。

难点

一、导入：

There is a book in the desk. There is a water bottle on the desk. There are two pens on the floor.

二、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：一共分为两种

①There is

+可数名词单数形式/不可数名词

There is a book on the desk.

3、就近原则

如果there be 句型中有两个或两个以上的主语时，be动词要和最靠近它的那个主语在数上保持一致。

如：

There is a pen and some books on the desk. 书桌上有一支钢笔和一些书。

主要教学过程

三、There be 句型的变化

1、变成否定句

There be+not+某人/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.

肯定句中有some时，要将其改为any。

如：

(1). There is a knife in the kitchen. 否定:There is not a knife in the kitchen.

(2)There are five apples on the tree.

否定:There are not five apples on the tree.

(3)There is some ink in the bottle.

否定:There is not any ink in the bottle.

练一练：把下列句子改成否定句

1.There are two cups on the table.

_______________________________

2.There are some beautiful flowers in the park._______________________ 3.

There is a tree in the garden.

________________________________

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. 如：

（1）There is a radio on the desk.

Is there a radio on the desk?

Yes, there is. / No, there isn’t.

（2）There are some shoes under the bed.

Are there any shoes under the bed?

Yes, there are. / No, there aren’t.

练一练：把下列句子改成一般疑问句:

1.There are four apples on the ground.

一般疑问句:____________________________________

2.There are some birds in the tree.

一般疑问句:____________________________________

3.There is a bird in the tree.

一般疑问句:____________________________________

四、总结:

There be口诀

There be 句型有特点，主语放在be后面。

主语三单用is, 主语复数要用are。

变否定，很简单，be后要把not添。

变问句，也不难，把be提到there 前。

肯定句中要用some, 否定疑问any换。
