Unit4语法讲解及习题：Using there is _ are ... -2025-2026学年沪教版英语七年级上册

沪教（牛津）英语七上Unit4语法讲解及习题 Using there is / are ... 一、语法核心讲解 本单元语法重点是 there is / are 句型，用于表达“某地存在某物”，核心是根据后面名词的单复数或可数/不可数来选择 is 或 are。 1. 基本用法与结构 there is + 单数可数名词 / 不可数名词 例：There is plastic pollution in the sea.（海里有塑料污染。） 例：There is a bottle on the beach.（沙滩上有一个瓶子。） there are + 复数可数名词 例：There are many bottles on the beach.（沙滩上有很多瓶子。） 例：There are plastic bags in the sea.（海里有塑料袋。） 2. 否定句与疑问句 否定句： there is → there is not (there isn’t) 例：There isn’t much clean water in the river.（河里没有很多干净的水。） there are → there are not (there aren’t) 例：There aren’t any fish in this lake.（这个湖里没有鱼。） 疑问句： Is there ...? → 回答：Yes, there is. / No, there isn’t. 例：Is there any rubbish on the beach?（沙滩上有垃圾吗？） Are there ...? → 回答：Yes, there are. / No, there aren’t. 例：Are there any sea animals in the polluted water?（被污染的水里有海洋生物吗？） 3. 就近原则（重要考点） 当 there be 后面跟多个并列名词时，be动词的形式由离它最近的那个名词决定： 例：There is a lot of plastic rubbish and many paper bags on the beaches. （离be动词最近的是不可数名词rubbish，所以用is） 例：There are many paper bags and a lot of plastic rubbish on the beaches. （离be动词最近的是复数名词bags，所以用are） 4. 常见缩写形式 there is = there’s there is not = there isn’t there are = there’re there are not = there aren’t 二、综合练习题 题型1：单项选择 1.
