小学五年级英语:There be句型精讲
一、什么是There be句型?
There be句型是英语中最常用的句型之一,用来表示"某地有某物/某人"。它描述的是存在的关系。
📌 在五年级考试中,There be句型是必考点,掌握它能让你的英语表达更加地道!
基本结构
There be + 名词 + 地点状语
│ │ │
│ 什么东西 在哪里
│
表示"有"
例如: - There is a book on the desk. → 书桌上有一本书。 - There are many students in the classroom. → 教室里有很多学生。
二、There be句型的三种核心句型
句型1:肯定句
| 结构 | 用法 | 例句 |
|---|---|---|
| There is + 可数名词单数/不可数名词 + 地点 | 后面跟单数或不可数名词 | There is an apple on the table. |
| There are + 可数名词复数 + 地点 | 后面跟复数名词 | There are two cats under the chair. |
句型2:否定句
在be动词(is/are)后面加 not。
| 肯定句 | 否定句 |
|---|---|
| There is a dog in the room. | There is not (isn't) a dog in the room. |
| There are books on the shelf. | There are not (aren't) books on the shelf. |
小技巧: - is not = isn't - are not = aren't
句型3:一般疑问句
把be动词(is/are)提到句首,句尾加问号。
| 肯定句 | 一般疑问句 | 肯定回答 | 否定回答 |
|---|---|---|---|
| There is a pen in the bag. | Is there a pen in the bag? | Yes, there is. | No, there isn't. |
| There are apples on the tree. | Are there apples on the tree? | Yes, there are. | No, there aren't. |
三、There be句型的"就近原则"
这是There be句型最重要的规则!🔥
就近原则: There be句型中,be动词的单复数由最靠近be动词的名词决定。
规则对比
| 句子 | be动词 | 原因 |
|---|---|---|
| There is a book and two pens on the desk. | is | 最近的名词"a book"是单数 |
| There are two pens and a book on the desk. | are | 最近的名词"two pens"是复数 |
口诀记忆
就近原则要记牢,is还是are看最近; 单数不可数用is,复数名词用are。
四、There be vs. Have的区别
这是同学们最容易混淆的知识点!❌
| 句型 | 含义 | 用法 | 例句 |
|---|---|---|---|
| There be | 某处有某物 | 表示"存在",强调位置 | There is a park near my home. |
| Have/Has | 某人有某物 | 表示"拥有",强调归属 | I have a new bicycle. |
判断口诀:
天上地下有什么,要用There be来述说; 人拥有什么东西,have/has来把握。
练一练: 1. 我有一本有趣的书。 → I have an interesting book. ✓ 2. 书桌上有一本有趣的书。 → There is an interesting book on the desk. ✓
五、There be句型的时态变化
| 时态 | 结构 | 例句 |
|---|---|---|
| 一般现在时 | There is/are... | There is a park near my school. |
| 一般过去时 | There was/were... | There was a party yesterday. |
| 一般将来时 | There will be... | There will be a test next week. |
注意: 将来时中,无论后面是单数还是复数,都用 There will be(will后面跟动词原形)。
六、趣味练习

- There ___ three birds in the tree.
- There ___ some milk in the glass. (milk是不可数名词)
