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 claroom? 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 claroom.
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 hand.Who 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 cup.There are some water in the cup.But this one.(指名学生说另一个空杯子) S:There......T:Is there any milk in the gla? S:Yes,There is/There isn’t.T:There are some water in the cup.S:Are there any water in the cup? T:Yes.There 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。
