被动语态
的有关信息介绍如下:被动语态是英语语法中的一种语态,表示主语是动作的承受者,即主语是动作的对象而不是执行者。被动语态由“助动词be + 动词的过去分词”构成,其中助动词be有时态、人称和数的变化。被动语态的时态变化主要改变be的形式,而过去分词部分保持不变。被动语态的构成和用法在不同年级的英语课程中会有所不同,通常在初中或高中阶段开始教授。被动语态的基本结构包括:一般现在时:主语 + am/is/are + 过去分词,例如:Trees are planted every year.现在进行时:主语 + am/is/are + being + 过去分词,例如:The road is being repaired.现在完成时:主语 + have/has + been + 过去分词,例如:The work has been finished.一般过去时:主语 + was/were + 过去分词,例如:The story was told by him.过去进行时:主语 + was/were + being + 过去分词,例如:The new house was being painted when I got home.过去完成时:主语 + had + been + 过去分词,例如:He told me that the work had been finished.一般将来时:主语 + will + be + 过去分词,例如:The problem will be discussed tomorrow.过去将来时:主语 + would/should + be + 过去分词,例如:He said that the Christmas tree would be put up soon.被动语态的例句有:Some festivals are held to honour the dead. (有些节日是为了纪念死者而举行的。)Your speech was heard by a group of five judges all of whom agreed that it was the best one this year. (你的演讲由5个评委听了,他们一致认为这是本年度最佳的演讲。)He is being interviewed now. (他正在接受采访。)被动语态在英语学习中非常重要,因为它可以帮助表达不清楚动作执行者的情况,或者强调动作的承受者。此外,了解被动语态的不同时态形式可以帮助更准确地使用英语进行交流和写作。
