3、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 ou

4、r classroom.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：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 arent any pictures on the wall. =

5、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 f

6、ish 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 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 c

7、omputer 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+is there+介词短语？【考查点】三there be 句型的时态。 be可以有现在时（there is/are）、过去时(there was/were)、将来时(there is/are going to be或there will b

8、e)和完成时(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. 【考查点】四there be 句型的主谓一致 There be 结构中的be动词要和后面所跟名词保持一致,遵循就近原则。 如：There isnany ri

There are two boys and a girl under the tree. 【考查点】五 there be 句型反意疑问句的构成：be (not) there? 如：There is some milk in the bottle, isnt 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“

10、某人拥有某物/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.

11、um.
