宾语是谓语动词的对象.PPTVIP

英语的两大语态：主动语态和被动语态 A.主动语态中主语是谓语动词的发出者。宾语是谓语动词的对象。 B.被动语态中主语是谓语动词的承受者(动作的对象)。 (把主动语态改为被动语态也就是把主动句中的宾语改为被动句的主语，这是最关键的着眼点，同时谓语动词作相应的变化。) 被动语态的谓语构成:　助动词be＋动词过去分词 什么时候要用被动语态呢？ 在下列三种情况之一要用被动语态： ①不知道动作的执行者是谁，用被动语态。 ②没有必要指出谁是动作的执行者，用被动语态。 ③需要强调动作的承受者时，用被动语态 主动句中谓语动词的发出者由by引出，作为by的宾语，也可以省略。 请看以下主动语态和被动语态结构的转换： 主动语态:主语＋谓语＋宾语 被动语态: 例： We clean our classroom every day. （主动） 　　 　　 [注意]①把主动语态改为被动语态时，句子的时态不能变。如上 例，所给的主动句子是一般现在时，改为被动语态时，也 要用一般现在时。 　　　②如果主动句中的主语是人称代词，改为被动句时作介词 by的宾语，要用宾格。如上例中的主语we改为us。 把下列主动句改为被动句 ①Lily writes many letters every day.
