核心语法：There be句型 + 方位介词与介词短语

一、There be句型

1. 基本规则

表示"某地有某物"，be动词与最近主语一致(就近原则)

- 单数/不可数名词：There is (There's)

- 复数名词：There are

2. 句型结构

句型	结构	例句
肯定句	There is + 单数/不可数名词	There is a book on the desk.
肯定句	There are + 复数名词	There are three pens in the bag.
否定句	There isn't + 单数/不可数名词	There isn't any water.
否定句	There aren't + 复数名词	There aren't any students.
疑问句	Is there + 单数/不可	Is there a library?

	数名词?
疑问句	Are there + 复数名词?	Are there any computers?

3. 就近原则

There is a pen and two books on the desk. (be动词随a pen变化)

二、方位介词及短语

介词	含义	例句
on	在...上面	The cup is on the table.
in	在...里面	My keys are in the bag.
under	在...下面	The ball is under the chair.

课堂练习

语法点1：There be句型

一、基础题

1.               ______ there any water in the bottle?（ ）
   A. Is     B. Are     C. Do      D. Does
   答案：A
   解析：考查There be句型的一般疑问句，主语water是不可数名词，用is。

二、培优题

（ ）1.There ______ some books and a pen in my schoolbag.
A. is   B. are    C. have   D. has
答案：B
解析：考查There be句型的就近原则，靠近be动词的主语some books是复数，故用are；易错点延伸：区分There be与have（表示“拥有”），避免出现There have/has的错误表达。

三、易错题

（ ）1.—There isn't a library in our school. —______.
A. Yes, there is  B. No, there is  C. Yes, there isn't  D. No, it isn't
答案：A
解析：考查There be句型否定句的肯定回答，结构为“Yes, there is/are.”；易错点：误选D，用it替代there，或出现Yes与isn't、No
