3、考察点】一 there be 句型根本情况1定义：There be句型表示某处存在某物或某人。2. 构造：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 classro

4、om.我们教室里有一位老师和许多学生。 There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。【考察点】二there be 句型的各种句型转化。1.变成否认There be句型的否认式的构成和含有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：not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 aren't any pictures on the wall. =Ther

5、e are no pictures on the wall. There is a bike behind the tree. There isn't 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否认变化也一样。如：There is some water on Mars. Is there any water on Mars? There are some fi

6、sh 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，那么用who 引导，当主语是物的时候，那么用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的单数形式答复时却要根据实际情况来决定。如： There are many things over there. What's over there? There is a little girl in the room.Who is in the room? 2对地点状语提问：那么用where 引导。如： There is

7、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,一般有两种句型构造： How many+复数名词+are there+介词短语？ How much+不可数名词+is there+介词短语？【考察点】三there be 句型的时态。 be可以有如今时there is/are、过去时there was/were、将来时there is/are going to be或there will be和完

8、成时there have/has been；还可用there must be ,there cant be, there used to be等。 如： -There is going to /will be a concert this evening. -Yeah. Exciting news! There is going to / will be a football match on TV this evening. 【考察点】四there be 句型的主谓一致 There be 构造中的be动词要和后面所跟名词保持一致,遵循就近原那么。 如：There isnany rice in

9、 the bowl. There is a teacher and many students in our classroom. There are two boys and a girl under the tree. 【考察点】五 there be 句型反意疑问句的构成：be not there? 如：There is some milk in the bottle, isn't there? 【易错点】六 there be 句型与have句型的区别1 There be 句型和have都表示“有的含义。区别如下：There be表示“某处存在某物或某人；have表示“某人拥有某物

10、/某人，它表示所有、拥有关系。 如： He has two sons. 他有两个儿子。There are two men in the office. 办公室里有两个男人。2当have表示“包括、“存在的含义时，There be 句型与其可互换。如： A week has seven days. =There are seven days in a week. 一个星期有七天。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

11、it right away.A. isB. areC. hasD. have【答案】A【解析】此题考察there be句型的就近原那么。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。应选A。【例题2】【题干】There_ a football match on CCTV-5 at nine tomorrow evening. A. will have B. is going to be C. is having 【答案】B【解析】此题考察倒装句。There be句型表示“某地

12、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】考察there be构造的临近原那么。 解题思路：这是一个there be构造的句子，离系动词be最近的是不可数名词milk，故根据临近原那么，正确答案选B。【例题4】【题干】There _ going to be a basketball match this afternoon.A. are B

13、. is C. have D. will【答案】B【解析】考察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。四、课堂运用【根底】一 将以下句子变成否认句和一般疑问句。1.There is some water in the bottle.2.There are many apples in the box.二. 对句子划线部分提问。1.There are seven days in a week. 2.There are lots of books in our library.3.There i
