There be结构教学设计
——
一、教学内容:There be 结构的形式
二、教材学情分析:
我们当下使用的是PEP人教版教材,在小升初的复习中反复出现过There be 句型的各种时态句式,但学生对这个句型没有一个整体的把握和认识,对其肯定句、否定句和一般疑问句等方面的掌握还存在着漏洞。
??三、教学目标与要求:
1.????知识与能力:掌握该句型的基本用法,能读懂会运用。
2.????过程与方法:学会总结归纳和探索。
3.????情感态度与价值观:培养对英语学习和探究的兴趣。
四.????????教学重难点分析:
重点:There be 句型的各种句式且能在实际情境中灵活运用。
难点:There be 句型的疑问句。
五.????????课前准备:教案和PPT课件。
六.????????教学过程:
1.????Warm-up:
Free talk :
I have a room , there is / are ________ in it.
There is/are _____in my school.
(设计意图:通过这个环节,回顾there be 的用法)
2.????Presentation:
Step 1: There be 结构的肯定式
There be 结构的肯定式主要有以下两种形式:
There is +可数名词单数/不可数名词+地点/时间状语。如:
There is a book on the desk.
There is some water in the bottle.
(2)There are +可数名词复数+地点/时间状语。如:
There are some flowers in the vase.
Step 2: There be 结构的否定式
There be 结构的否定式是在谓语动词后加“not”或“no”,表示“没有”之意。如果句子中有some,变否定句时需将some变为any。如:
There are not any /no flowers in the vase.
花瓶里没有花。
There are not any /no flowers in the vase.
花瓶里没有花。
Step 3: There be 结构的疑问式
(1)一般疑问句及其答语
There be 结构变成一般疑问句时,要把be动词提至there前,首字母大写,句末用问号。其肯定回答用“Yes,there is /are.”;否定回答用”No,there isn't/aren't.”。如:
—Is there a computer in your room?
—Yes,there is./—No,there isn't.
(2)特殊疑问句及其回答
①提问句子的主语(包括主语前的修饰语)时,句型一律用:What is +地点介词短语?(无论主语是单数还是复数都用is)。如:
There are some birds in the tree.
→What's in the tree?
②提问可数名词(主语)前的数量时,用how many,句型结构为:How many +复数名词+are there+其他?(主语无论是单数还是复数,be动词通常要用are)。如: There is a cat under the bed.
→How many cats are there under the beds?
温馨提示:There be 结构变为疑问句时,如果句中有some要将其改为any。
就近原则:(there be 是个近视眼)
如果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保持一致。如:
There is a pen and two rulers on the desk.
There are two rulers and a pen on the desk.
(设计意图:这个环节内容相对较多,知识点也多,所以采用小组合作学习的模式,在每位同学认真学习思考的前提下,充分与小组成员交流,取长补短,培养学生的合作探究能力。用从具体到抽象再到具体的模式,让学生通过例子总结出句型结构,在运用句型结构进行语言的再造,这样可以一方面加深学生对所学知识的印象,另一方面更能培养学生的语言运用能力和学习能力。)
3. Practice:
Ss do the exercise individually.
一、用is或are填空。
1. There________ three cups of coffee on the table.
2. There________some pencils in the pencil box.
3. There________nothing in the bag.
二、用所给单词的适当形式填空。
1. There is some ________(bread) on it.
2. There are 5 basketball________(play) in every team.
3. There aren't________(some) knives in the room.
4. There ______ (be) an English evening(晚会) next Tuesday.
5. There________(be) not a bird in the sky.
三、按要求改写句子。
1. There was a wallet on the seat just now.
(改为否定句和一般疑问句)
(1)There________ ________ a wallet on the seat just now.
(2)______ _______ a wallet on the seat just now?
Check the answers according to the teacher’s.
(Ss discuss in groups.T give help if necessary.)
(设计意图:练习是必要的巩固阶段,让学生知道答案,更应该让学生知道选择这个答案的原因,学生自己探究出的答案,比老师告诉的要更加意义深刻理解透彻)
