there be微课教案.doc

There be句型微课教学设计教学目标:1、掌握Therebe结构所表达的意义。2. 正确使用There be句型的肯定，否定及一般疑问句形式3.掌握Therebe结构的回答方式。重点难点therebe句型的肯定式、否定式一般疑问句及其回答方式。教学方法:讲授法、分组讨论法、任务型教学法、多媒体教学教学过程一、 导入：翻译下列句子。w There is a zoo in my neighborhood.w There is a big park across from the supermarket. There be 结构w There are some books on the desk.w There are many people in the hall.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There is +可数名词单数形式/不可数名词 There is a book on the desk. 桌子上有一本书。 There is some water in the bottle. 瓶子里有一些水。There are +可数名词的复数形式 There are some pictures on the wall. 墙上有些图画。 There are two apples in the basket. 篮子里有两个苹果。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。There are some books and a pen on the desk. 书桌上有一些书和钢笔。练一练：看名词1. There _a clock on the table. A. is B. are 2. There _some water in the bottle. A. are B. is3. There _some students in the classroom. A. are B. is 4. There _ a pencil, a book and two pens on the table. A. is B. are 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isnt，are not的缩写是arent. 当肯定句中有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 isnt.2. There are some shoes under the bed.Are there any shoes under the bed? Yes, there are. / No, there arent.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有特点， 主语放在be后面。be可变身is/are， there永远不变化。单数is复数are， 不可数的还是is它。变疑问很简单， be须大写来提前。变否定也不难， be后要把not添。肯定句中用some， 否定疑问any换。多个主语并列用， 就近原则来通融。地点是位大个子， 排队站在最后面。五、Homework 语法整理一遍背诵六、教学反思本节课知识量较大，需要同学们掌握的知识点不少，但同时一般现在时是我们所接触的第一个时态来讲不是太难。且我们从刚接触英语就是一般现在时，其中的很多知识结构我们已经在
