七年级上册Unit 3 My School语法总结 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 一、基本概念 方位介词用于表示事物之间的位置关系，通常与There be句型搭配使用，描述某物在某处的具体位置。 方位介词示意图 桌子 ↑ on (在...上面) ↓ under (在...下面) ← left of (在...左边) → right of (在...右边) ↙ in front of (在...前面) ↗ behind (在...后面) in (在...里面) near (在...附近) between (在...之间) 二、常用方位介词 介词 含义 示例 in 在...里面 The books are in the bag. (书在包里) on 在...上面（接触表面） The pen is on the desk. (钢笔在桌子上) under 在...下面 The cat is under the table. (猫在桌子下面) behind 在...后面 The playground is behind the building. (操场在楼后面) in front of 在...前面 There is a tree in front of our classroom. (教室前有棵树) next to 紧挨着 The library is next to the science lab.

(墙上有张地图) 多个介词使用 描述复杂位置时可使用多个介词 The ball is under the chair in the corner. (球在角落的椅子下面) 易混介词区分 on/above/over; under/below; between/among The picture is on the wall. (接触) A bird is flying above the house. (不接触) ❗ 重要提示： · 注意区分in和on：in表示在内部，on表示在表面 · in front of表示在物体外部的前面，in the front of表示在物体内部的前部 · between用于两者之间，among用于三者或以上之间 · 方位介词后接名词、代词或动名词作宾语 三 练习1：There be句型转换 1.肯定句变否定句：There is a computer in the classroom. ___________________________________________ 2.肯定句变一般疑问句：There are some books on the shelf. ___________________________________________ 3.对划线部分提问：There are thirty students in my class. ___________________________________________ 用正确形式填空：There ______ (be) a pen and two pencils in the box. 用正确形式填空：There ______ (be) some milk in the glass. 练习2：方位介词填空 1.
