There be结构

教学目标：

1．学习There be结构的定义。

2．理解掌握There be的各种结构：肯定式、否定式、一般疑问句及肯否定回答的知识框架。

教学重难点：

There be的否定式、疑问句中，当句子中有“some”的时候，需把“some”变为“any”。

教学用具：实物各种水果、学习用具、卡片、杯子等

教学流程：

一、课前导入.

1、师生日常会话，谈自己的教室内的物品布置,让学生用There be 句型描述教室有什么物品。

T: Hello, children. What’s in our classroom S1: There is/are…

2、教师揭示引出There be结构的定义。

There be结构又称存在句，表示某地存在某物。

如：There is a book on the desk. There are four desks in the classroom. 二、教授新课。

步骤1：教师拿出水果描述，引出There be结构的肯定式。

、教师展示水果。

T：Do you like fruits S:Yes, I do.

T:What do you like fruits S:I like .....

T：What’s this/these S:It’s a pear./pears.

T:How many pears are there on the desk S:There is /are .. On the desk.

看例句：There is a pen on the desk.

There is some water in the cup. There are two pens on the desk

师生互动练习,找规律：（注意some用在肯定句中）

There is a computer on the desk. There is some bread on the plate.

There are two boys under the tree.

结构：There is+单数或不可数名词+某地 There are+可数名词的复数形式+某地

.表示：在某地有某物或某人。

小结There be结构的肯定式：

板书： There be (is/are)+名词（单数/复数）+地点状语。

2.就近原则：

(1)看例句

There is a pen and two books on the desk. There are two books and a pen on the desk. (2)找规律

在there be 句型中，如有几件物品，be 动词的选择取决于最靠近它的那个名词，我们常称之为“就近原则”。There is a computer and two cups on the desk. There are two cups and a computer on the desk.

步骤2：教师拿出学习用具描述，引出There be结构的否定式。

、教师展示文具。

T:I have many pencils in my can Count it

S: one、two.......

T:How many pencils are there in my hand.

S:There are ......in your hand.

T:How many pens are there in my hand(此时教师并非手中拿钢笔）

S：No......

教师让学生两人一组，拿出文具进行对话练习。（注意any用在否定句中）

There is not a duck in the river.

小结There be结构的否定式：there be句型的否定句在be 动词后加not ,

板书：There be (is/are)+not+名词（单数/复数）+地点状语。

步骤3：教师拿杯子（分有水还是无水）描述，引出There be结构的一般疑问句及肯否定回答。

、教师拿出两个杯子中的水进行描述。

T：Everyone，Look at my are some water in the this one.(指名学生说另一个空杯子）S：There......

T：Is there any milk in the glass S:Yes,There is/There isn’t.

T:There are some water in the cup. S:Are there any water in the cup

T: are/There aren’t

师生互动练习。（注意any用一般疑问句中）

小结There be结构的疑问式。

板书：Be(is/are)+there+名词（单数/复数）+地点状语。

步骤4：教师以班级男生和女生的数量，引出There be结构的特殊疑问句形式。

、教师分别叫一名男生和女生对本班学生进行数一数。

S1：Boys....... S2: girls.......

师生互动练习。

小结There be结构的特殊疑问句。针对数量提问的特殊疑问句的基本结构是：

How many +名词复数 + are there + 介词短语

How much + 不可数名词 + is there + 介词短语

特殊疑问词+be(is/are)+there+地点状语。

三、巩固练习。

1、把下列句子变成否定句、疑问句及做肯否定回答。

There is a house on the farm。 There are some chairs in the classroom.

2、看图说句子。

四、课后思考。Homework
