(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
4、,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 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no
5、t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. =There are no pictures on the wall.

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: Th
7、ere 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 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+
8、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 be)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.

10、 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“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.
