Unit 1 Science Fiction Discover Useful Structures 被动语态复习 教案-2026-2027学年人教版（2019）高中英语选择性必修第四册

人教版（2019）选择性必修第四册 Unit 1 Science Fiction Period 2 Discover Useful Structures 被动语态复习 教案 教材分析 本节课是人教版（2019）选择性必修第四册 Unit 1 Science Fiction 的 Period 2 Discover Useful Structures，语法点为被动语态的综合复习。学生在初中和前面几个单元已经接触过被动语态的基本形式，但对进行时被动、情态动词被动以及不同时态被动的混合运用掌握不牢。课本这部分以科幻作品为载体，本节课紧扣单元科幻主题，以武汉城市发展与光谷科技未来为情境重新组织例句和练习，让学生在贴近生活又充满未来感的语境中梳理被动语态的各种形式和语用功能，避免单纯讲规则的枯燥感。 教学目标 1. 通过观察例句，归纳被动语态的各种形式（各时态、情态动词、非谓语动词）。 2. 在描述武汉城市建设、光谷科技与未来生活的语境中正确运用被动语态。 3. 判断被动语态的使用场景，体会被动语态在书面表达中的语用功能。 教学重难点 重点：各时态被动语态（一般现在/过去/将来、现在完成、现在进行）及情态动词被动的结构与基本用法。 难点：① 现在进行时被动语态（is/are being done）的结构；② 主动语态与被动语态的语用选择（写作中何时用被动）。 Teaching Procedures Step 1 Lead-in（约5分钟） Teacher: Good morning, class. Today we're going to review passive voice. Let's start with some places we all know in Wuhan. Look at the sentences and fill in the blanks with the correct form. Two minutes. Look at the scenes of Wuhan and fill in each blank with the correct form of the word in brackets. 1. The East Lake Greenway ____________ (build) and opened to the public in 2016. Now it is loved by people of all ages. 2. More high-tech companies ____________ (attract) to Wuhan's Optics Valley nowadays. The city is becoming a hub of innovation. 3. Wuhan hot dry noodles （热干面） ____________ (enjoy) by local people for breakfast every morning. 【设计说明】用学生天天经过的武汉地标引入，不急于讲规则，先让学生在熟悉的语境中感知被动语态的不同形式，为后面的归纳做铺垫。 Step 2 Analyze and Identify（约15分钟） Task 1 Complete the sentences Teacher: Now look at these sentences about Wuhan. Complete them with the correct passive form. Five minutes, then we check together. 1. The Yellow Crane Tower ____________ (visit) by millions of tourists every year. 2. The Wuhan Yangtze River Bridge ____________ (build) in the 1950s. It is called “the First Bridge over the Yangtze River”. 3. The 7th Military World Games ____________ (hold) in Wuhan in 2019. Many new sports facilities were built for it. 4. Right now, more intelligent manufacturing robots ____________ (use) in factories across Wuhan. 5. The cherry blossoms at Wuhan University ____________ (enjoy) by thousands of visitors every spring. 6. A new science fiction exhibition hall in East Lake High-tech Development Zone ____________ (design) now. It will open to the public next year. 【设计说明】这6句覆盖一般现在、一般过去、现在进行三种最常用的被动形式，先让学生独立填，做完直接核对答案，为后面归纳形式攒下例句。 Task 2 Active vs Passive Teacher: Good. Now, change this sentence into active voice. What's the difference? Which one puts more focus on the event? The 7th Military World Games was held in Wuhan in 2019. 【设计说明】让学生通过主动和被动的对比，自己体会被动语态的语用功能——强调动作的承受者或事件本身，而不是动作的发出者。 Task 3 Find different forms Teacher: Read these sentences again. Can you find all the different forms of passive voice? Discuss with your partner. Three minutes. 1. The Yellow Crane Tower is visited by millions of tourists every year. 2. The Wuhan Yangtze River Bridge was built in the 1950s. 3. A new artificial intelligence research center in Optics Valley is being built and will be put into use next year. 4. The Yangsigang Yangtze River Bridge has been praised as one of the longest bridges of its kind in the world since it opened in 2019. 5. A future technology experience center along the Yangtze will be completed and opened to the public next year. 6. The broken playground facilities must be repaired before the school sports meeting. 【设计说明】把不同时态和情态动词的被动放在一起让学生找，比一条一条讲规则印象更深。学生自己找出来的形式，后面总结的时候更容易记住。 Step 3 Summarize（约10分钟） Teacher: Now work with your partner. Based on the sentences we just read, summarize all the forms of passive voice. I give you one minute to think, then we share. Task 1 Summarize the forms Basic form: be + v.-ed • Present simple: am/is/are done • Past simple: was/were done • Future simple: will be done • Present perfect: have/has been done • Present continuous: am/is/are being done • Modal verbs: must/can/should be done • Non-finite: to be done Task 2 When do we use passive voice? Teacher: Now think about this question. When do we use passive voice instead of active? Discuss in pairs. 【设计说明】形式总结放第二步之后，学生已经有了足够的例句支撑，归纳水到渠成。语用功能（什么时候用被动）单独拿出来讨论，因为学生往往只记形式不记用法，写作文的时候乱用被动。 Step 4 Practice（约12分钟） Task 1 Talk about Wuhan Teacher: Now practice. Work in pairs. Talk about one place in Wuhan that you like best. Use at least 3 passive sentences. Four minutes, then I'll ask some pairs to share. Example: The East Lake Greenway was built in 2016. It is used by people for running and cycling. More trees have been planted along the lake. Task 2 Complete the passage Teacher: Next, read the introduction to Wuhan and complete the passage with the correct forms. Five minutes. locate build visit connect consider Wuhan ____________ in central China. It ____________ as one of the most important transportation hubs in China. The three towns of Wuhan ____________ by bridges and tunnels across the two rivers. For thousands of years, many famous bridges ____________ across the rivers. The most famous one, the Wuhan Yangtze River Bridge, ____________ in 1957. Now, Wuhan ____________ by more and more tech companies and visitors from all over the world every year. Task 3 Write a short paragraph Teacher: Finally, suppose you are introducing Wuhan to a foreign friend. Write 5-6 sentences. Use passive voice as much as possible. Three minutes, then we read a few aloud. 【范文参考】Wuhan is a wonderful city located in central China. It is known as the "River City" because the Yangtze River and the Han River are connected here. The Wuhan Yangtze River Bridge is called "the First Bridge over the Yangtze River". The East Lake Greenway is loved by local people for running and cycling. More high-tech companies are being attracted to Optics Valley every year. The Yellow Crane Tower is visited by millions of tourists annually. The cherry blossoms at Wuhan University are enjoyed by thousands of visitors every spring. I hope you will be shown around this amazing city soon! 【设计说明】Task 1是口头输出，Task 2是语篇填空输入，Task 3是笔头输出，从易到难层层递进。全部围绕武汉本地话题，学生有话可说，不会觉得没东西写。 Step 5 Summary（约3分钟） Teacher: OK, take one minute. Think about what we reviewed today. Can anyone tell me two key points about passive voice? 学生口头总结，教师补充并板书要点。 【设计说明】让学生自己说比教师直接念板书印象深，教师只在学生说不全时补漏，最后把形式和语用两条线落回板书。 Homework 1. Write a short introduction (80-100 words) to your favourite place in Wuhan. Use at least 5 passive sentences. 2. Finish the exercises on Workbook “Reviewing useful structures”. Blackboard Design Passive Voice Review Basic form: be + v.-ed Forms: • tenses: am/is/are done / was/were done / will be done have/has been done / am/is/are being done • modal verbs: must/can/should be done • non-finite: to be done Use: • don't know the doer • emphasize the receiver / the action 教学反思 这节课用武汉本地例子贯穿，学生的反应比预想的好一些，黄鹤楼和长江大桥的句子一出来，确实有学生在下面小声说“这我熟”；讲到光谷人工智能中心和科幻展厅那几句时，后排几个男生明显抬头了，科技话题比纯城市地标更能抓住他们。Lead-in 和形式归纳这两块进展顺利，大部分学生能自己说出被动语态的基本结构。 进行时被动（is being done）花的时间比预计多，有几个学生一直搞不清为什么要加 being，后来用“光谷人工智能中心正在被建”这个例子才勉强讲通，但我感觉他们还是半懂不懂，后面练习中还得再碰到几次才能真正消化。 语用功能（什么时候用被动）是这节课的重头戏。有学生问“那我写作文是不是多用被动显得高级”，说明他们对被动的使用场景理解还不到位，光靠讲一遍不够，得在后面的写作课里反复强化。语篇填空的第4题“many famous bridges have been built”，班上错的人不少，好多人写了 were built，这个题以后讲之前可以先做个小铺垫，提示学生注意时间状语。 时间上还是前松后紧。Step 2 的句子核对给了5分钟但实际用了快7分钟，导致最后写作输出的分享比较仓促，只点了两个学生读。下次口头对话活动可以放课后，课堂上只做语篇填空和写作，把时间省给输出环节。基础弱的几个学生在非谓语被动部分明显跟不上，这个只能课后单独补，课堂上照顾不过来。 参考答案 Step 1 Lead-in 1. was built 2. are being attracted 3. are enjoyed Step 2 Analyze and Identify Task 1 1. is visited 2. was built 3. was held 4. are being used 5. are enjoyed 6. is being designed Task 2 Active: Wuhan hosted the 7th Military World Games in 2019. The passive sentence emphasizes the event itself, not the doer (Wuhan). We use passive when the action or the receiver of the action is more important. Task 3 Varied forms: present simple passive, past simple passive, present continuous passive, present perfect passive, future simple passive, modal verb passive. Step 3 Summarize Task 1 Basic form: be + v.-ed • Present simple: am/is/are done • Past simple: was/were done • Future simple: will be done • Present perfect: have/has been done • Present continuous: am/is/are being done • Modal verbs: must/can/should be done • Non-finite: to be done Task 2（参考答案） 1. When we don't know who performed the action. 2. When we want to emphasize the receiver of the action. 3. When the action itself is more important than the doer. Step 4 Practice Task 2 is located; is considered; are connected; have been built; was built; is visited 学科网（北京）股份有限公司 $
