Unit 8 Is there a post office near here?,第三课时 (Grammar Focus3c)单元同步语法精讲精练,there be句型 定义：there be句型也称为“存在句”，表示“某地有某人/物”。 句式结构及用法 (1)there be句型的肯定句结构为：There be名词(主语)地点副词/介词短语(表示地点)。there be句型属于倒装句，主语通常放在谓语后面，动词be为谓语。be动词应根据主语的单复数而变化，主语是单数或不可数名词，用there is；若主语是复数用there are。 eg：There are 50 students in our class.我们班有50个学生。 (2)there be句型中的谓语应和后面的主语保持一致，若有两个或两个以上的主语，动词be的形式应由最近的那个主语的数决定，即遵循“就近原则”。,eg：There is a pencil and two books on the desk. There are two books and a pencil on the desk.课桌上有一支铅笔(两本书)和两本书(一支铅笔)。 (3)there be句型的否定句，直接在be动词后加not；其一般疑问句，要将be动词放在句首。肯定回答为“Yes，there is/ are.”；否定回答为“No，there isnt/ arent.”。 【注意】如果在there be句型的否定句和一般疑问句中有some，则应将some改为any。 (4)there be句型一般现在时的特殊疑问句由“特殊疑问词is/arethere地点状语”构成，有时地点状语可省略。答语不能用Yes或No，需根据情况直接回答。 eg：How many apples are there in the bag？包里有多少苹果？,Five.五个。 there be与have/has的区别 there be结构表示客观存在，意为“某地有某物(人)”；have/has表示所属关系，意为“某人拥有某物”。 eg：There is a TV in our classroom.在我们的教室里有一台电视机。 We have a TV in our classroom.我们有一台电视机在教室里。,一、用be动词的适当形式填空。(必要时可加not) 1There a park near here. 2 there any books on the desk?
