在学习英语的过程中，掌握时态和语态是非常重要的。时态用来表示动作发生的时间，而语态则表明动作的执行者和承受者之间的关系。为了帮助大家更好地理解和记忆，下面将通过一个简要的表格来梳理英语中的主要时态及其对应的语态。

| 时态 | 主动语态 | 被动语态 |

|--------------|--------------------------------|----------------------------------|

| 一般现在时| I write letters. | Letters are written by me.|

| 现在进行时| I am writing letters.| Letters are being written by me.|

| 一般过去时| I wrote letters. | Letters were written by me. |

| 过去进行时| I was writing letters. | Letters were being written by me.|

| 将来时| I will write letters.| Letters will be written by me.|

| 过去将来时| I would write letters. | Letters would be written by me. |

| 现在完成时| I have written letters.| Letters have been written by me.|

| 过去完成时| I had written letters. | Letters had been written by me. |

| 将来完成时| I will have written letters. | Letters will have been written by me.|

以上表格展示了英语中常见的几种时态以及它们在主动语态和被动语态下的表达方式。通过对比主动语态和被动语态的形式，我们可以看到，被动语态通常会在句子中加上“by”短语来明确动作的执行者。

熟练掌握这些时态和语态的使用方法，不仅能够提升我们的写作能力，还能让口语交流更加地道流畅。希望这个表格能为大家提供一定的参考价值，在日常学习中不断巩固和完善自己的语法知识。
