There Be句型与方位介词
第一部分：There Be句型
一、基本概念
There be句型表示"某处有某物"，用于描述事物的存在。基本结构为：There + be + 名词 + 地点状语。
示例：1. There is a book on the desk. (桌子上有一本书)
2. There are many students in the classroom. (教室里有许多学生)
3. There isn't a computer in my room. (我房间里没有电脑)
二、结构变化
句型 结构 示例
肯定句 There + is/are + 名词 + 地点 There is a map on the wall.
There are two libraries in our school.
否定句 There + is/are + not + 名词 + 地点 There is not (isn't) a clock here.
There are not (aren't) any books on the shelf.
一般疑问句 Is/Are + there + 名词 + 地点 Is there a computer in your classroom
Are there any students in the library
特殊疑问句 疑问词 + is/are + there + 地点 What is there on the desk
How many students are there in your class
三、使用规则
规则 说明 示例
就近原则 be动词的形式由最靠近它的名词决定 There is a book and two pens on the desk.
There are two pens and a book on the desk.
不可数名词 不可数名词用is，some修饰 There is some water in the bottle.
可数名词复数 可数名词复数用are，any/some修饰 There are some apples on the tree.
时态变化 过去时：There was/were；将来时：There will be There was a tree here last year.
There will be a meeting tomorrow.
重要提示：
There be句型表示"存在"，have/has表示"拥有"（There be ≠ have）
疑问句和否定句中常用any，肯定句中用some
回答There be疑问句：Yes, there is/are. 或 No, there isn't/aren't.
第二部分：方位介词
