时态（Tense）是英语语法的核心，用来表示动作发生的时间和状态。初中阶段主要学习五种基本时态，掌握各时态的用法、区别和相互转换是中考的重点。
一般现在时：习惯性动作、现在状态、客观真理
- 构成：动词原形/第三人称单数
- 标志词：always, usually, often, sometimes, every day
现在进行时：现在正在进行的动作
- 构成：am/is/are + 动词-ing
- 标志词：now, look, listen, at the moment
一般过去时：过去发生的动作或状态
- 构成：动词过去式
- 标志词：yesterday, last..., ago, just now
一般将来时：将来要发生的动作
- 构成：will + 动词原形 / be going to + 动词原形
- 标志词：tomorrow, next..., soon, in the future
现在完成时：过去动作对现在的影响，或从过去持续到现在
- 构成：have/has + 过去分词
- 标志词：already, yet, just, ever, never, since, for
I play / He plays
I am playing
I played
I will play
I have played
时态判断技巧：
1. 看时间状语（最直接）
2. 看上下文语境
3. 注意特殊句型（主将从现等）
易混时态对比：
- 一般现在时 vs 现在进行时：习惯 vs 正在进行
- 一般过去时 vs 现在完成时：具体过去 vs 对现在的影响
- will vs be going to：临时决定 vs 事先计划
时态转换：注意时间状语的相应变化
主将从现：时间、条件状语从句中用一般现在时表将来
