一、底层总逻辑
1. 世界只分两类:人 / 事物
2. 句子只分两类:- 讲状态 → 用 be动词
- 讲动作 → 用 do动词
二、be动词:只表“状态”
1. 三大基础用法
- be + 名词 → 是什么
This is a stone.
- be + 形容词 → 什么样
The stone is grey.
- be + 地点 → 在哪里
The stone is on the ground.
2. There be 句型
- 含义:某地有某物
- 结构:There be + 人/事物 + 地点
- 等价:The book is on the desk.
= There is a book on the desk.
3. be 动词变形口诀
- I → am
- you/复数 → are
- 单数名词/ he/she/it → is
- 过去:was(单)/ were(复)
三、do动词:只表“动作/行为”
1. 基础动作
- 结构:人/事物 + do + 宾语
I move the stone.
2. 能力 / 意愿
- can / will / may + 动词原形
I can move it.
I will move it.
3. 感官感受
- feel / look / sound / smell / taste + 形容词
The stone feels hard.
4. 比较与最高级
- 比较:比较级 + than
- 最高级:the + 最高级
This stone is bigger than that one.
四、动词三大“状态”
1. 持续态:正在做 / 一直做
- be + doing
I am moving the stone.
2. 完成态:已经做完 / 持续到现在
- have/has + done → 已经
I have moved the stone.
- have/has been + doing → 一直做到现在
I have been moving it for an hour.
3. 被动态:被……
- be + done
The stone is moved by me.
- have/get sth done → 把某事做完(让别人做)
I get the stone moved.
五、to do / will 表“将来/未发生”
- to do:想要、计划、目的
I want to move the stone.
- will + 动词原形:将要
I will move it tomorrow.
六、句式结构
1. 简单句
一套主谓:
- 主 + be + 表
- 主 + do + 宾
2. 从句
用引导词连接,修饰主干:
- 定语从句:who / which / that
- 条件从句:if
拆句万能步骤
1. 找主语(人/事物)
2. 找谓语(be / do)
3. 去掉修饰,先看懂主干
4. 再加修饰还原整句
七、最容易错的5点(必背)
1. 状态用be,动作用do,不能混用
✅ I run. ❌ I am run.
2. 第三人称单数动词要加 s/es
✅ He likes. ❌ He like.
3. There be 表“存在”,have 表“拥有”
✅ There is a book. ❌ There have a book.
4. 被动一定有 be
✅ The stone is moved. ❌ The stone moved.
5. 长句先抓主干,不要逐词翻译
