1、好好学习 天天向上敎學过程一、复习预习 敎师引导學生复习上节课所學内容;一般疑问句,由一般疑问句Are there any fish in the water? 导入本节课内容,并检查本节课學生预习作业。二、知识讲解知识点:there be 句型【考查点】一 there be 句型基本情况1定义:There be句型表示某处存在某物或某人。2. 结构:(1) There is +单数可数名词/不可数名词+ 地点状语. (2) There are +复数名词+地点状语.注意:there是引导词,在句中不充当任何成分,翻译时也不必译出。句子的主语是某人或某物,谓语动词be要与主语（某人或某物）的数

2、保持一致。当主语是两个或两个以上的名词时,谓语动词要与跟它最近的那个名词一致。如: There is a bird in the tree. 树上有一只鸟。 There is a teacher and many students in our classroom.我们敎室里有一位老师和许多學生。 There are two boys and a girl under the tree. 树下有两个男孩,一个女孩。【考查点】二there be 句型的各种句型转化。1.变成否定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或no即可。注意not和no的不同:n

3、ot是副词,no为形容词,not a/an/any + n. 相当于no+ n.。 如: There are some pictures on the wall. There arent any pictures on the wall. =There are no pictures on the wall. There is a bike behind the tree. There isnt a bike behind the tree. =There is no bike behind the tree.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

4、句尾加上问号即可。但同时要注意:当肯定句中有some时,要将其改为any（否定变化也一样）。如:There is some water on Mars. Is there any water on Mars? There are some fish in the water. Are there any fish in the water? 3.特殊疑问句1）对主语提问:当主语是人的时候,则用who 引导,当主语是物的时候,则用what 引导。注意:无论原句的主语是单数还是复数,对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如: There are many things

5、over there. Whats over there? There is a little girl in the room.Who is in the room? 2)对地点状语提问:则用where 引导。如: There is a computer on the desk. Where is the computer? There are four children on the playground. Where are the four children? 3）对数量提问,一般有两种句型结构: How many+复数名词+are there+介词短语？ How much+不可数名词

6、+is there+介词短语？三、例题精析【例题1】【题干】David, there _ a dictionary and some books on your desk. Please put them away. OK. Mum. Ill do it right away.A. isB. areC. hasD. have【答案】A【解析】本题考查there be句型的就近原则。There be后面接并列名词时,谓语动词 be 应与最邻近的名词在数上保持一致, 首先排除C、D项。又因为句中的名词为单数a dictionary,由此可排除B项。故选A。【例题2】【题干】There_ a foo

7、tball match on CCTV-5 at nine tomorrow evening. A. will have B. is going to be C. is having 【答案】B【解析】本题考查倒装句。There be句型表示“某地有某物”或“某时有某人”;have“有”,指人有,故答案选B。【例题3】【题干】There _ still some milk in the fridge. Its not necessary to go to the store today.A. am B.is C.are D. be【答案】B【解析】考查there be结构的临近原则。 解题思路

8、:这是一个there be结构的句子,离系动词be最近的是不可数名词milk,故根据临近原则,正确答案选B。【例题4】【题干】There _ going to be a basketball match this afternoon.A. are B. is C. have D. will【答案】B【解析】考查there be句型的主谓一致。 在there be句型中be与后面的真正主语保持一致,a basketball match单数形式,故用is。课程小结 本节课围绕there be 句型展开,重点内容为there be句型的各种句型转化、时态、主谓一致、以及there be 句型的反意疑问句。通过讲、练、测结合,使學生掌握了该知识点的基本用法,并重点强调了考点和易错点,使學生能够灵活使用该知识点,从而全面提升了其英语语言应用能力.2
