初中英语中，动词的时态是非常重要的语法点，它帮助我们表达动作发生的时间。其实初中阶段掌握好这9种时态就可以了。以下是英语中几种基本的动词时态，以及它们的用法和例句：
1. 一般现在时（Simple Present Tense）
- 用法：表示经常性或习惯性的动作，或表示普遍真理。
- 例句：She works at a school.（她在一所学校工作。）
2. 一般过去时（Simple Past Tense）
- 用法：表示过去某个时间发生的动作或状态。
- 例句：He visited the museum last week.（他上周参观了博物馆。）
3. 一般将来时（Simple Future Tense）
- 用法：表示将来要发生的动作或状态。
- 例句：They will travel to Japan next year.（他们明年将去日本旅行。）
4. 现在进行时（Present Continuous Tense）
- 用法：表示现在正在进行或发生的动作。
- 例句：We are having a class meeting now.（我们现在正在开班会。）
5. 过去进行时（Past Continuous Tense）
- 用法：表示过去某个时间正在进行的动作。
- 例句：It was raining when I left the house.（我离开房子时正在下雨。）
6. 将来进行时（Future Continuous Tense）
- 用法：表示将来某个时间点正在进行的动作。
- 例句：She will be working at 10 a.m. tomorrow.（明天上午10点她将在工作。）
7. 现在完成时（Present Perfect Tense）
- 用法：表示过去发生的动作对现在有影响或结果。
- 例句：They have finished their homework.（他们已经完成了作业。）
8. 过去完成时（Past Perfect Tense）
- 用法：表示在过去某个时间或动作之前已经完成的动作。
- 例句：She had left before I arrived.（我到达之前她已经离开了。）
9. 将来完成时（Future Perfect Tense）
- 用法：表示在将来某个时间点之前会完成的动作。
- 例句：We will have learned 3000 words by the end of this term.（到这个学期结束时，我们将学习3000个单词。）
每种时态都有其特定的构成方式，通常是通过变化动词的形式来表达。例如，一般现在时中，主语是第三人称单数时，动词要加-s或-es；进行时态中，使用“be”动词的相应形式加上“-ing”形式的主动词。
