2、的承受者 2. 被动语态的构成 被动语态由助动词 be+及物动词的过去分词构成。助动词 be 有人称、时态和数的变化。 3. 被动语态的用法：当说话者不知道动作的执行者或没有必要指出动作的执行者时，只需要强调动作的承 受者，可以使用被动语态。如果需要在被动语态中指出动作的执行者时一般用介词 by 引出。 Chinese is spolen by the largest number of people in the world. 汉语是世界上为最多人所讲的语言。 4. 一般现在时的被动语态 （1）一般现在时的被动语态的构成：在一般现在时态的句子中，被动语态由be(am/is/are) + 及物
