教学课件 沪教（牛津）英语七年级上册 Unit 4 语法专项—— There is / there are 全解精讲+分层练习 1 学习目标 1.理解 there be 句型表示“某地存在某物”。 2.掌握 there is 与 there are 的用法区别。 3.熟练使用 否定句与一般疑问句结构。 4.掌握并运用 就近原则解题。 5.能完成单选、句型转换、填空、情景对话。 6.能正确描述环境、垃圾、物品的存在。 There be 句型—核心定义 There be 句型表示“某地有某物/某人”。 它强调存在，不强调所属关系。 结构：There + be + 名词 + 地点。 注意：there 在这里没有实际意义。 be动词的形式由后面的名词决定。 There is 用法 there is 用于： 1.单数可数名词前（a / an + 名词） 2.不可数名词前（water, rubbish, pollution） 例句：There is a bottle on the beach. 例句：There is pollution in the sea. be动词只能用is。 There are 用法 there are 用于： 复数可数名词前（名词+s/es）。 常见标志词：many, some, lots of + 复数。 例句：There are many fish in the river. 例句：There are some bags on the floor. be动词只能用are。 否定句构成 否定句在 be动词后 + not。 there is → there is not = there isn’t there are → there are not = there aren’t 否定句中 some 常变为 any。 例句：There isn’t any water here. 例句：There aren’t any parks nearby. 一般疑问句构成 疑问句把 be动词提到 there 前面。 Is there + 单数/不可数名词…? 回答：Yes, there is. / No, there isn’t. Are there + 复数名词…? 回答：Yes, there are. / No, there aren’t. 就近原则（最重要考点） 当有多个名词并列时，be动词由最近的名词决定。 靠近单数 → 用is 靠近复数 → 用are 例句：There is a pen and two books. 例句：There are two books and a pen. 只看离be最近的那一个名词。 some & any 在 there be 中的用法 some 用于肯定句：表示“一些”。 There is some milk. any 用于否定句和疑问句。 There isn’t any milk. Is there any milk? 这是考试常考细节。 There be 与 have/has 的区别（重点） 核心区别：There be 表“存在”，have/has 表“所属”。 1. There be：强调某地有某物，无所属关系，主语是“存在的事物”。 例句：There is a book on the desk.（桌上有一本书，书不属于桌子） 2. have/has：强调某人/某物“拥有”某物，有明确所属关系，主语是人/物。 例句：I have a book. ；He has a pen. 易错提醒：两者不可连用，不能说“There has a book”或“I there have a book”。 对比练习：There be vs have/has Our school ________ a big library. ________ ________ a big library in our school.
