一、什么是简单谓语？
简单谓语是英语句子的核心成分，指由单个动词或动词短语构成的谓语，用来表达主语的动作或状态。它不包含多个动词并列或复合结构，而是最简单直接的谓语形式。
核心定义：简单谓语 = 单个动词（或动词短语）充当句子谓语，表示主语执行的动作或存在的状态
| 谓语类型 | 构成方式 | 示例 |
|---|---|---|
| 简单谓语 | 单个动词/动词短语 | She works efficiently. |
| 复合谓语 | 情态动词+动词原形 | She can work efficiently. |
| 并列谓语 | 多个动词并列 | She works and studies every day. |
二、简单谓语的构成形式
简单谓语主要由实义动词构成，通过时态、语态、人称和数的变化来适应不同语境的需要。
1. 时态形式变化
| 时态 | 构成方式 | 示例 |

| 一般现在时 | 动词原形/第三人称单数 | He writes a letter. |
| 一般过去时 | 动词过去式 | He wrote a letter. |
| 现在进行时 | am/is/are + 现在分词 | He is writing a letter. |
| 现在完成时 | have/has + 过去分词 | He has written a letter. |
2. 语态形式变化
| 语态 | 构成方式 | 示例 |
|---|---|---|
| 主动语态 | 主语执行动作 | The cat caught the mouse. |
| 被动语态 | be动词+过去分词 | The mouse was caught by the cat. |
