时态的被动语态结构
被动语态是指在主语执行动作的时候，受动作影响的对象成为句子的主语，而主语则变为宾语的语法结构。
在英语中，被动语态有不同的时态形式，下面是其常见的时态被动语态结构：
1. 现在时被动语态：am/is/are + 过去分词
例如: The book is being read by me.（这本书正在被我阅读）
2. 过去时被动语态：was/were + 过去分词
例如: The letter was written by him last night.（这封信昨晚被他写了）
3. 将来时被动语态：will + be + 过去分词
例如: The work will be finished by the end of this week.（这项工作将在本周末完成）
4. 现在完成时被动语态：have/has + been + 过去分词
例如: The house has been built for two months.（这幢房子已经建成两个月了）
5. 过去完成时被动语态：had + been + 过去分词
例如: The decision had been made by the committee before I arrived.（这个决定在我到达之前已经被委员会做出了）
注意，在使用被动语态时，主语变为宾语，谓语动词的过去分词形式放在be 动词后面。
同时，主语在句子中通常会被放在by 后面，表示动作执行的对象。
但有时候，by 短语也可以省略。
现在完成时的被动语态句型结构
现在完成时的被动语态句型结构现在完成时的被动语态是英语中常用的一种句型结构，它表示某个动作或状态已经发生，并且强调其结果或影响。
下面将详细介绍现在完成时的被动语态句型结构。
1. 结构现在完成时的被动语态由“have/has been + 过去分词”组成。
其中，“have/has”表示主语已经经历了某个过程，而“been”则表示这个过程是以被动形式进行的。
“过去分词”则是指原来的动词变为了过去式形式。
例如：- The book has been read by many people.（这本书已经被很多人读过了。
）- The car has been repaired by the mechanic.（这辆车已经被修理工修好了。
）2. 用法现在完成时的被动语态通常用于以下情况：(1) 强调结果：该句型可以强调一个行为、事件或状态所带来的结果，而不关注具体执行者。
例如：- The cake has been eaten.（蛋糕已经吃掉了。
）- The report has been submitted to the manager. （报告已提交给经理。
）(2) 描述事实：该句型也可以描述一件事情发生后留下来的事实和状况。
例如：- Many houses have been destroyed in the earthquake.（地震摧毁了许多房屋。
）- A lot of money has been spent on this project so far. （到目前为止，在这个项目上花费了大量资金。
）(3) 表示重复性行为：有些行为可能会反复进行，此时使用现在完成时的被动语态可以更准确地表达出这种意思。
例如：- This room hasn't been cleaned for weeks! （这间房子几周没打扫过啦！）- How many times have you been told not to touch that? （你听说那东西不能碰多少次啦？）3. 注意点当使用现在完成时的被动语态时需要注意以下几点:(1) 主要谓语必须是“have/has”，否则就不符合该句型结构规范；(2) 被强调对象应放置于“by”的后面；(3) 当没有明确提及执行者或无需知道执行者身份时，则可省略“by”。
