1、初中重点语法There be句型全解析1. 定义：There be句型表示某处存在某物或某人。2. 结构： (1) There is/was +单数可数名词/不可数名词+ 地点状语. (2) There are/were +复数名词+地点状语.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。eg. There is a bird in the tree. 树上有一只鸟。 There is a teacher and many students
2、in our classroom. There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。3. There be句型与have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。 eg.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。 e
3、g.A week has seven days. =There are seven days in a week. 变脸一：否定句 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.。例如： 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 be
4、hind the tree. There isnt a bike behind the tree. =There is no bike behind the tree.变脸二：一般疑问句 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）。看看下面两句是如何改头换面的吧：There is some water on Mars. Is there any water on Mars?There are some fish in the water. Are there any fish in
5、the water?变脸三：特殊疑问句 There be句型的特殊疑问句形式有以下三种变化： 对主语提问：当主语是人时，用Whos+介词短语?；当主语是物时，用Whats + 介词短语?。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? 对地点状语提问：提问地点当然用Where is / are+主语?啦！例如：There is a computer on the desk. Where is the computer?There are four children on the playground. Where are the four children? 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？第 2 页 共 2 页
