Work on 4a
Read the sentences. Circle the verbs in the passive voice.
the passive voice
被动语态
含义
被动语态：主语不是发出动作，而是承受、接受这个动作，也就是主语是动作的承受者。
What is the passive voice
Active Focus: Passive Focus:
For example
Engineers design the object on a computer.
(Focus on the people)
The object is designed on a computer.
(Focus on the invention)
Active vs Passive
Raise your left hand for an active sentence and your right hand for a passive sentence.
Marconi invented the radio.
The radio was invented by Marconi!
ACTIVE
PASSIVE
Why do we use the passive voice
Like a movie, every sentence has a star. We use the passive voice when the receiver of the action is the real star of the show.
含义
1. Unknown doer
Example: My bike was stolen last night.
In a film, a prop is stolen. We never see the thief. The stolen prop is the focus, not the unknown bad guy. We put the prop in the “camera spot” as the subject.(e.g., A radio message was sent.)
2. Doer is not important
Example: Rice is grown in the south.
A documentary films rice fields. Everyone knows farmers grow rice. We keep the camera on rice, and do not show farmers on screen. We leave out the well-known doer.
含义
3. Highlight the receiver
Example: The letter was written by Tom.
A letter drives the story. Tom writes it, but the letter is the real star. The camera focuses on the letter. We add “by Tom” to show who works behind it.
4. Objective style for reports
Example: The experiment was conducted under strict conditions.
For news or documentary films, we hide the reporter. We only show facts, not “I / we”. Passive voice helps us sound neutral.
What is the structure of the passive voice
主语 + am /is/are
/was/were done +（by sb）+ 其他。
主语 + am /is/are
/was/were not done +（by sb）+ 其他。
Am / Is /Are/Was
/Were + 主语 + done +（by sb）+ 其他？
疑问词 + am /is/are/was/
were + 主语 + done +（by sb）+ 其他？
结构
Subject + Modal (can/will/must) + be + Past Participle
We clean the classroom every day.

Object becomes the new subject. Use am / is / are + past participle. Add “by…” to show the doer.

Use 4+ correct passive sentences, including had to be done. No mistakes in was/were or past participles.
Speak coherently. Retell in your own words with full key information.
All members speak at least one sentence. Work well together.
Q1: Why are so many passive sentences used in the passage about the Qinghai-Xizang Railway
We focus on the projects and results rather than the builders. Passive voice is often used to introduce great works in news and texts.
Q2: Many great inventions and projects are made by people. Should we remember the people who created them, besides the projects themselves Why
Yes. Amazing achievements come from people’s hard work and wisdom. We should value both the results and the people behind them.

一、教材分析 Analysis of teaching material
What: 本板块为语法聚焦，核心是被动语态，由三项梯度任务构成。1. 4a：阅读例句，圈出句中的被动语态动词。呈现一般现在时、一般过去时、含情态动词的被动语态典型例句，感知 be+过去分词 结构。2. 4b：用括号内动词的正确形式补全单句，在单句层面操练不同时态被动语态，主语与动词的语态匹配。3. 4c：语篇填空，完成关于青藏铁路的短文，在完整语篇语境中运用被动语态，同时生成青藏铁路人物简介，实现语法结合主题语篇输出。语言点：被动语态（一般现在、一般过去、情态动词被动） be + done ；主题词汇与青藏铁路相关背景知识。文本结构与语言特点：由简单例句→单句填空→完整说明文语篇，难度层层递进；例句简短典型；4c文本是事实说明类说明文，句式丰富，融合主动、被动语态，兼具知识性与育人内涵。 Why:1. 语言能力：帮助学生识别、理解被动语态结构，掌握不同时态下被动语态变形，能够在句子、语篇中正确运用被动语态来描述发明、重大工程。2. 思维品质：遵循感知 操练 运用的语法学习逻辑，从识别到单句再到语篇，培养观察归纳、分析推理能力。借助青藏铁路语篇，引导学生感悟我国重大工程成就。3. 文化意识：依托青藏铁路素材，感受中国建设成就，增强民族自豪感。4. 学习能力：学生自主观察归纳语法规则，在真实语篇中运用语法，学会在语境中判断语态，提升语法运用能力。
How:1. 语法感知 4a学生朗读句子，圈画被动语态动词；教师引导学生观察句子，归纳 be+过去分词 被动语态基本结构，区分一般现在、一般过去、情态动词被动形式。 文本特点：4a为简短事实例句，句式精炼，突出语法结构，便于学生聚焦语法形式。 2. 单句操练 4b学生独立完成单句填空，核对答案；重点点拨主语和动词主动、被动关系，区分时态，巩固单句层面被动语态变形。由短句练习夯实语法基础。3. 语篇运用 4c①通读青藏铁路短文，把握说明文文本结构：介绍工程概况→建设难题与解决措施→工程价值意义。语言上大量使用被动语态讲述工程建设。②学生完成语篇动词填空，结合上下文判断时态、语态。③填空完成后，基于短文信息完成青藏铁路简介输出，把语法知识融入主题表达。4. 总结巩固梳理三类被动语态结构，区分主动与被动的使用场景；结合发明、工程主题造句，实现语法服务于主题表达。
二、教学内容 Teaching content
1. 阅读例句，圈画出句中的被动语态动词，感知一般现在时、一般过去时、情态动词的被动语态基本结构。2. 用括号内动词的正确形式补全句子，在单句语境中练习不同时态被动语态，掌握动词变形规则。3. 阅读青藏铁路说明文，结合语境填写动词正确形式，在完整语篇中综合运用被动语态。4. 根据短文信息完成青藏铁路人物简介输出，将语法知识和主题语篇结合，实现语法的综合迁移运用。
