五、语法知识
📌 被动语态系统精讲(一般现在时 & 一般过去时)
【一、什么是被动语态?】
◆ 主动语态:主语是动作的执行者 → The boy broke the window.
◆ 被动语态:主语是动作的承受者 → The window was broken by the boy.
◆ 使用场景:不知道动作执行者/强调动作承受者/客观陈述
【二、被动语态结构公式】
◆ 核心公式:be + 过去分词(be动词随时态变化)
◆ 加by短语引出执行者(可省略):be + 过去分词 + (by + 执行者)
【三、一般现在时被动语态】
◆ 结构:am/is/are + 过去分词
English is spoken in many countries.(许多国家说英语)
The file is read by the 3D printer.(文件被3D打印机读取)
The windows are cleaned every day.(窗户每天被打扫)
◆ 否定:am/is/are + not + 过去分词
English is not spoken in this country.
◆ 疑问:Am/Is/Are + 主语 + 过去分词?
Is English spoken in Japan? — Yes, it is.
【四、一般过去时被动语态】
◆ 结构:was/were + 过去分词
The telephone was invented by Bell in 1876.(电话由贝尔于1876年发明)
The window was broken yesterday.(窗户昨天被打破了)
These houses were built last year.(这些房子是去年建的)
◆ 否定:was/were + not + 过去分词
The message was not sent successfully.
◆ 疑问:Was/Were + 主语 + 过去分词?
Was the telephone invented in 1876? — Yes, it was.
【五、主动变被动的"三步法"(必考!)】
Step 1:找出原句的宾语 → 变为主语
Step 2:把动词变为"be + 过去分词"(be随时态变化)
Step 3:原句主语变为by短语(可省略)
主动:Bell invented the telephone in 1876.
被动:The telephone was invented (by Bell) in 1876.
【六、被动语态高频考点提醒】
◆ ⚠️ 不及物动词无被动!(happen, occur, break out, take place等)
❌ The accident was happened yesterday. → ✅ The accident happened yesterday.
◆ ⚠️ 双宾语动词(give/send/show/tell)变被动,两种均可:
He gave me a book. → I was given a book. / A book was given to me.
◆ ⚠️ make/let/have + 宾语 + do(主动省to)→ 被动时to要还原:
主动:He made me laugh. → 被动:I was made to laugh.(to不能省!)
【七、高频不规则动词过去分词(必背)】
invent → invented(规则) discover → discovered(规则)
make → made write → written send → sent
break → broken build → built speak → spoken
teach → taught think → thought find → found
