英语的被动语态是一种描述动作或事件的承受者的语法结构，通常由“be”动词的不同形式和过去分词构成。被动语态在各种语境中都很常用，例如描述实验结果、技术规格、表达礼貌或避免责任。然而，有些动词不适合用于被动语态，或者用起来含义不明确。学习者需要掌握被动语态的基本用法和语法规则。
例如，下列句子中的被动语态：
- The cake was made by my mom. (这个蛋糕是我妈妈做的。)
- The book has been read by many people. (这本书被很多人读过。)
- The car will be repaired by the mechanic. (这辆车将由技工修理。)
被动语态在英语中非常常用，它可以用于各种语境和情况。例如，在科技领域，被动语态常用于描述实验结果或技术规格：
- The new software has been tested extensively. (新软件已经经过大量测试。)
- The device will be upgraded next month. (设备将在下个月升级。)
被动语态还可以用于表达礼貌或避免责任：
- The mistake was made, but it will be corrected soon. (错误已经发生，但很快会被纠正。)

需要注意的是，有些动词不适合用于被动语态，或者用起来含义不明确：
