（Lesson 25 Smiths kitchen） Teach Plan组员： 教学对象：初一年级学生，学生成绩较差，部分学生学生比较沉闷，需要老师多关注和提醒。学情：他们已学过了how many, where 引导的特殊疑问句以及由be动词引导的一般疑问句及其肯否回答，这些知识点可以为本节课服务。同时，他们能够听到课堂指令语和日常交际用语，并能够做出相应的回应和回答。Teaching aims:1. 学生能够掌握There be 句型的单数形式句型（肯定句，否定句和一般疑问句）。2. 学生能够对There be 句型的复数形式句型（肯定句，否定句和一般疑问句）有一定的了解，为下节课做铺垫。3. 复习冠词a, an, the的用法。4学生能够了解介词in, on的用法及介词短语in the kitchen, on the left, on the right, on the table 的含义。5学生能够了解以下扩充词语的含义：right, left, cook, room。Teaching keys and difficult points:1. 学生能够掌握There be 句型的单数形式句型（肯定句，否定句和一般疑问句）。 Teaching aids:1.

Great！One for you.(在教师多次输入there be 句型后引导学生口头输出 there be 句型)We can say “There is a boy on the left of the ground.” Follow me. There is a boy on the left of the ground.S S: There is a boy on the left of ground.T：What can you see on the left of the boy?One! Two! Hands up!S b: Snowman. （抽举手手最快学生回答，回答正确以作为奖励机制，回答错误，及时纠正）T: Clever! We can say “There is a snowman on the left of the boy”. Follow me! There is a snowman on the left of the boy.S b: There is a snowman on the left of the boy.T: Great. One for you.T：What else can you see on the snow?Ss: Some boxes.T: Yes, there are some boxes on the snow. So, you should say “There are some boxes on the snow.” T: Great. One for you. T: All of you read the five sentences please. One, two, go.（播放有以下5个句子的PPT）Sentence 1: There is some snow on the ground.Sentence2: There is a boy on the left of the ground. Sentence 3: There is a snowman on the left of the boy.Sentence4: There are some boxes on the snow.Sentence5: There are some Christmas trees on the snow.T: Good! 看这几个句子，大家能发现什么？Ss: 前3个句子都有 there is， 后2个句子都有there are.（给回答问题的学生奖励）T: 是的，is 和are都是什么词？Ss:都是be动词T:我们可以用一句话来概括这五个句子，都由there be 构成,T: 那我们一起来看这几句话是什么意思。谁愿意翻一下这几个句子呢？（老师先引导学生翻译前两个句子，再让学生自主翻译后3个句子，若学生翻译错时，老师给予及时纠正）Ss: (老师给回答正确的组加分奖励，并将ppt 播放到有汉语翻译的一页。)T:非常棒，从刚才的几个句子的意思来看，都表示“某地有某物”。 因此there be句型翻译为“某地有某物”。 T:现在一起观察这几个句子（引导学生一起找出句子的主语和谓语及主语后面的句子成分）Sentence 1: There is some snow (主语) on the ground（介词短语）.Sentence2: There is a boy(主语) on the left of the ground（介词短语）. Sentence 3: There is a snowman (主语)on the left of the boy（介词短语）.Sentence4: There are some boxes(主语) on the snow（介词短语）.Sentence5: There are some Christmas trees (主语)on the snow（介词短语）.T: 从刚才的分析中，我们可以得出there be 句型肯定句的结构是：There be + 主语 + 介词短语。T:在例句中我们看到了be动词的哪2种形式，Ss:is 和are。T: 那什么时候用is,什么时候用are呢？(引导学生观察be 动词和主语的变化以发现并总结there be 句型的3种结构。)T: 第一句中主语是？Ss: a boy T: 谓语呢？Ss：是is, T: a boy是几个人？Ss: 一个。T:那a boy 是单数还是复数？Ss: 单数。(用同样的方法分析其他句子。第二句中主语是a snowman , 是单数，谓语是is。第三句中主语是some snow, snow是不可数名词，前面用some来修饰，谓语是is。第四句的主语是some boxes , 是复数，谓语是are。第五句的主语是some Christmas trees ， 是复数，谓语是are。) T：因此，我们可以得出there be 句型的两种结构：There be +可数名词单数+介词短语；There be + (some)+不可数名词+介词短语；There be + (some)+可数名词复数+介词短语。都翻译为“某地有某物”。（将ppt 播放到有there be 句型定义、结构的页）T:大家抄下来。Ss：抄笔记T: Are you finished?Ss: Yes.T：现在我们用“there be + 主语 + 时间地点” 这个结构在造个句。比如：桌子上有一本书。我们就可以说：T and Ss: There is a book on the desk.(口头翻译即可)T:有一支钢笔在手里呢？Ss：There is a pen in my hand. (口头翻译即可)T: 那再来看着几个例句。我们要怎样把他们变为一般疑问句呢？T:我们之前学过变一般疑问句的口诀，大家一起来回顾一下。T: 那这几个句子都有be 动词，所以我们要按照be动词的句子来变换句子。我们前面说了对有be 动词的陈述句变一般疑问句的口诀（be 提前并大写，其余照抄，句末问，若遇 some 变 any），这儿我们用它来对there be 句型进行句型转换。（通过引导学生通过复习由be 动词构成谓语动词的句子变一般疑问句的方法，否定句以及肯否回答来引出并呈现there be 句型的引导的一般疑问句，否定句，以及引出there be 句型的一般疑问句的肯否回答Yes, there is. No, there are.）T: 之前我们学习由be动词引导的一般疑问句时，讲到了把陈述句变成一般疑问句，有个口诀就是：有be提be，有情找情，无情五be就借助,把陈述句变为否定句，直接在be动词的后面加“not”。因此there be 句型里面本身含有be动词，把陈述句变成一般疑问句时，直接把be动词提到there的前面。把肯定句变成否定句直接在be动词后面加“not”就可以了，其结构为：一般疑问句：Be there + 主语 + 时间地点（板书） 否定句：There be + not + 主语+时间 肯定回答：Yes，there is.否定回答：No，there isnt (is not)T：比如，桌子上有一本书吗？我们就可以说 Is there a book in the desk?T：那桌子上没有书。这个句子该怎么表达？Ss：There is not a book in the desk.T: Very good! Ok, listen，I have a question for you.Step3: Drills and PracticeT: What are there in the classroom?Sa: There are some desks in the classroom.T: Well done! One for your group.T: What else？Ss：There is a whiteboard on the wall.SS: There are some chairs in the classroom.SS: There is a door on the wall.SS: There are two windows on the wall.T: Good job! 现在老师要求你们把你们所表达的句子变为一般疑问句，那应该怎么表达呢？Ss：here isnt a whiteboard on the wall.SS: There arent some ch
