Unit1 information and Media语法讲解与练习 被动语态语法详细讲解 1. 被动语态定义 英语语态分为主动语态和被动语态。主动语态强调动作的发出者；被动语态强调动作的承受者。 例：People check news every day.（主动，强调人们） News is checked every day.（被动，强调新闻） 2. 被动语态基本结构 核心公式：be +及物动词过去分词（done）+（by +动作执行者） 关键：be动词随时态、人称、单复数变化，过去分词永远不变 3. 结构（Unit1必考） 时态 被动语态结构 单元例句 一般现在时 am/is/are + done News is released on smartphones every day. 一般过去时 was/were + done The old news stand was shut down last year. 一般将来时 will be / am/is/are going to be + done False news will be checked strictly. 情态动词 情态动词(can/must/should) + be + done Information should be cross-checked. 4. 主动变被动核心步骤 ① 主动宾语 → 被动主语（代词变主格） 规则：主动句里作宾语的名词/代词，放到被动句开头，充当新主语；如果是代词，宾格必须改为主格。 例1（代词）：Active: We help him. Passive: He is helped (by us). 例2（代词）：Active: The story moves her. Passive: She is moved (by the story). ② 谓语动词 → be +过去分词（匹配时态、单复数） 规则：删掉主动谓语动词，换成 be + done（过去分词）；be动词的时态、单复数，跟着被动句新主语变化。 例1（一般现在时）：Active: They write articles. Passive: Articles are written (by them). 例2（一般过去时）：Active: He saved the old photo. Passive: The old photo was saved (by him). ③ 主动主语 → by +宾格；日常/新闻文本中常省略by短语 规则：原来主动句的主语，放在介词by后面，代词要变回宾格；当动作执行者不重要、未知或者无需强调时，by+执行者可以直接省略（阅读、新闻高频）。 例1（保留by+宾格）：Active: She finished the task. Passive: The task was finished by her. 例2（省略by短语，新闻常用）： Active: Someone discovered the secret. Passive: The secret was discovered.（by someone省略） 5. 必考特殊考点 ❶ 不及物动词无被动语态：happen, take place, appear, break out（新闻场景高频） ❷ 感官/使役动词被动还原to：make/let/have/see/hear 主动省to，被动必须加to 例：People see him report news. → He is seen to report news. ❸ 固定搭配不丢介词：look after, listen to, take care of 等短语动词变被动，介词不可省略 ❹ 无被动特殊句型：sell/write/read 等动词+副词（well/easily），主动表被动 例：This news app sells well.（不用is sold） 第二部分 配套专项练习 大题一：用所给单词适当形式填空 根据句意和被动语态规则，填写单词正确形式 1.
