2019春中考英语复习课件：第九章被动语态(共19张PPT)

语态是动词的一种形式，用以说明主语与谓语动词之间的关系。动词的语态有两种：主动语态和被动语态。主语是动作的执行者时为主动语态，主语是动作的承受者时为被动语态。被动语态是动词的一种特殊形式，一般说来，只有及物动词和一些相当于及物动词的词组才有被动语态。汉语往往用 “被、受、给” 等词来表示被动意义。 第九章　被动语态 1．被动语态的构成 被动语态由 “be＋过去分词 (p.p.)” 构成。人称、数和时态的变化是通过be动词的变化来表现出来的，过去分词部分不变。疑问句和否定句的变化也如此。 时态 被动语态的结构 举例 主动语态 被动语态 一般现在时 am / is / are＋p.p. I clean the room. The room is cleaned by me. 一般过去时 was / were＋p.p. He cleaned the room. The room was cleaned by him. 一般将来时 will / be going to＋be＋p.p. He will clean the room. The room will be cleaned by him. 2.被动语态的用法 用法 举例 (1) 当不知道动作的执行者是谁，或没必要指出动作的执行者是谁时 The book is written for children. (2) 强调或突出动作的承受者时，而不强调动作的执行者时 The window was broken yesterday. (3) 当动作的执行者不是人而是无生命的事物时 Many houses were destroyed by the accident. 考点1　一般现在时的被动语态 (主语＋am / is / are＋p.p.) 肯定句 否定句 一般疑问句 The floor is cleaned every day. The floor isn't cleaned every day.
