被动语态讲解
被动语态讲解什么是被动语态被动语态（Passive Voice），是英语语法中的一种语态。
这种语态表示主语是动作的承受者，而不是执行者。
换句话说，被动语态将动作的焦点从主动者转移到受动者。
英语的被动语态由be + 过去分词组成，其中be的形式为 am、is、are、was、were、been 和 being。
例如：主动语态：The cat chased the mouse.（猫追逐老鼠。
）被动语态：The mouse was chased by the cat.（老鼠被猫追逐。
）被动语态的结构被动语态的结构是由不同的“助动词”（auxiliary verbs）构成的，并且根据所使用的时态和语气而变化。
以下是不同时态和语气下的被动语态结构：•现在时被动语态：am/is/are + 过去分词–例如：The ball is being thrown.（球正在被扔。
）•过去时被动语态：was/were + 过去分词–例如：The ball was thrown by him.（那个人扔了球。
）•现在完成时被动语态：have/has been + 过去分词–例如：The cake has been eaten.（蛋糕已经被吃了。
）•过去完成时被动语态：had been + 过去分词–例如：The book had been read by her.（那本书被她读过了。
）•将来时被动语态：will be + 过去分词–例如：The package will be delivered tomorrow.（那个包裹明天会被送到。
）•条件语句被动语态：would be + 过去分词–例如：The room would be cleaned if requested.（房间被要求打扫。
）如何使用被动语态被动语态可以用于正式、书面或学术场合中描述一种被动的行为或过程，这种行为或过程是无人为的或与某个人的主观行为无关的。

例His mother gave him a present for his birthday.可改为 He was given a present by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。
