Unit4语法(there be句型)讲解与练习-2026-2027学年沪教版英语七年级上册暑假衔接预习

Unit4 The Earth语法讲解与练习 there be 句型（一般现在时）详细讲解 一、核心定义（课本必考） there be 句型含义：表示 某地有某人/某物（强调“存在”） ⚠️ 重点区分： have / has：强调拥有、所属（人/物拥有某物） there be：强调存在、坐落（某地存在某物，无所属关系） 单元例句：There are many forests on the Earth. 地球上有许多森林。 二、一般现在时 there be 核心结构 一般现在时中，there be 只有两种形式：there is / there are 1. There is +单数名词/不可数名词+地点 适用：单数物品、水、空气、土地、时间等不可数名词 例句：There is clean air in the forest. 森林里有清新的空气。 例句：There is a river near the village. 村子附近有一条河。 2. There are +可数名词复数+地点 适用：多个可数人或事物 例句：There are many animals on the Earth. 地球上有很多动物。 例句：There are different plants in the world. 世界上有各种各样的植物。 三、三大完整句式（考试100%必考） 1. 肯定句 公式：There is / There are + 名词 + 地点状语 There is some water on the ground. 地上有一些水。 There are many trees around our school. 我们学校周围有很多树。 2. 否定句 公式：There is / are + not + 名词 + 地点 缩写：isn’t / aren’t 例句：There isn’t any clean water here. 这里没有干净的水。 例句：There aren’t many wild animals in this area. 这个区域没有很多野生动物。 ⚠️ 必考细节：否定句中 some 必须改为 any 3. 一般疑问句（问答口诀：用什么问，用什么答） 公式：Is / Are + there + 名词 + 地点？ 肯定回答：Yes, there is. / Yes, there are. 否定回答：No, there isn’t. / No, there aren’t. 例句：— Is there a park near your home? 你家附近有公园吗？ — Yes, there is. / No, there isn’t. 例句：— Are there many flowers in the garden? 花园里有很多花吗？ — Yes, there are. / No, there aren’t. 四、就近原则（单元最大考点、易错点） 就近原则口诀：be动词看最近的名词，不看后面所有名词 1. There is a book and two pens on the desk.（最近a book单数→is） 2. There are two pens and a book on the desk.（最近two pens复数→are） 五、some & any 必考用法（搭配there be专用） 1. some：用于肯定句，一些 2. any：用于否定句、疑问句，一些/任何 ✅ There issome rain in summer.（肯定） ✅ There isn’t any rain in winter here.（否定） ✅ Is there any water in the bottle?（疑问） 六、there be 和 have/has 终极辨析 ❌ 绝对错误：there have / there has（中式英语，考试零分） ✅ 正确区分： 1. There be + 地点：某地有…（存在） There are many trees on the Earth. 2. 主语 + have/has：某人/某物拥有…（所属） The Earth has many beautiful forests. 七、单元话题满分例句（背诵适配Unit4地球主题） 1.
