2024年中考英语复习主动语态 转换成 被动语态课件

当主语是动作的执行者时,动词用主动语态(Active Voice);如果主语是动作的承受者,动词便用被动语态(Passive Voice)。 Many students study English.(主动语态) English is studied by many students.(被动语态) 结构是 be+动词的过去分词 (be+V.P.P) 2)被动语态的结构: 被动语态由“be+动词的过去分词”构成,助动词be有人称、数的变化,其时态变化规则与be作为连系动词时一样。 如:The desk is made of wood. The desks are made of wood. He is asked a question by the teacher. I am given a nice present by my friend. 在改写中应注意: 1.把原来的宾语提到前面作被动语态的主语; 2.把动词变成“be + 过去分词”; 3.主动语态中的主语变为介词by的宾语。 典型题例 例1 将下列句子改为被动语态。 We clean our classroom every day. Our classroom is cleaned (by us) every day. 主变被解题步骤: 1. 找宾语 -即动作的承受者 They make shoes in that factory. Shoes 2. 判断宾语的单复数 -即be动词的单复数. are 3. 判断动词的时态 -即be动词的时态. 4. 修改谓语的形式-即原句动词改为过去分词 made 5. 修改原句的主语 -即by+ 主语.(主格变宾格) by them. 6. 句式同步-即主动句是否定形式,被动句也是否定形式。 主动句是一般疑问,被动句一样。 一般现在时的被动语态: am/are/is + 过去分词 People play football all over the world. 2.
