Unit 3 Environmental Protection Using language 写作课导学案-2025-2026学年高中英语人教版选择性必修第三册

2025-2026学年高二下学期 人教版（2019）选择性必修第三册 Unit 3 Environmental Protection Period 4 Reading for Writing 导学案 编制单位 XX中学高二英语备课组 适用年级 高二（下） 备课人 __________ 审核人 / 适用班级 __________ / 高二（ ）班 教材依据 人教版（2019）选必第三册 Unit 3, Page ____ 课时 Period 4 / 1 课时（45′） 姓名：__________ 小组：__________ 日期：__________ 【Learning Aims】 1. 快速读完课文，能说出漓江曾经遇到什么污染、政府采取了哪些主要措施。 2. 理清文章四段结构（问题→原因→措施→展望），能自己画出简单的结构图。 3. 从课文里找出至少5个因果和措施类的表达，写作文时能用得上。 4. 照着四段结构，写一篇100词左右的身边环境问题小报道。 【学情备忘（上次作文暴露的问题）】 上次Unit 2作文收上来批改，班里同学写环保话题主要有三个毛病： ① 句子之间没连接词，一句一句像流水账，读着散——比如只写“The river is dirty. Many fish die.”，中间不加because / as a result。 ② 时态混用，写“已经采取的措施”还在用过去式——上次作文里一半同学写“The government took action since 2020”，应该用现在完成时。 ③ 写成口号式议论文，动不动就“We must protect the environment!”，不会客观地分层陈述问题、原因、措施。 这节课不要求背多少好句，核心是把四段框架搭起来，以后遇到环保类写作直接套。 课前小测（5 分钟，上课铃响即做） Diagnosis 1 选词填空（because / as a result / thanks to，每词只用一次）： (1) The river is dirty __________ too much waste is poured into it. (2) __________, many fish have died. (3) __________ the new rules, the water is getting cleaner. Diagnosis 2 改错： The local government took action to protect the river since 2020. ______________ Diagnosis 3 头脑风暴： Write down TWO environmental problems you can see around you. (1) __________________ (2) __________________ ⏱ 收上来快速扫一眼：Diagnosis 1错得多→课上重点带因果连接词；Diagnosis 2错得多→写作文时反复提醒现在完成时。两个都不错就直接进课文，别浪费时间。 【Key Points & Difficulties】 ★ 重点：读懂课文，理清结构；下面这几个表达写作必须会用—— · 因果类：have a bad effect on / do harm to / lead to / contribute to · 措施类：take measures to... / steps should be taken to... / ... be carried out （后面Step 2表格里的句子也可以用，不局限于上面这几个。） ▲ 难点：别照着课文抄，要能把课文里的表达迁移到自己身边的话题上；因果措施之间要有逻辑链，别光罗列事实。 Part Ⅰ Lead-in 导入（约 5 分钟） ⏱ 老师课前找个30秒漓江风光短视频（或者直接翻课本插图），上课先放，叫学生用一个英语形容词说第一印象。没人举手就点前排的，别冷场。 Activity 1 生词过一遍 左边单词连右边释义，给1分钟，同桌互相对答案。错得多的词课上带读两遍，别单独讲。 1. volume a. an official rule 2. regulation b. the amount of sth. 3. sustainable c. to deal with a problem 4. tackle d. able to last a long time 5. disposal e. getting rid of sth. Activity 2 看图聊两句 Guilin is on the Li River. Every year millions of visitors go there. Work in pairs and talk: What may happen to a clean river when too many tourists come? Who do you think should be responsible for the dirty river — visitors, boatmen, factories or the government? ⏱ 叫2组说思路就行，老师别急着给标准答案——故意留着疑问，等读完课文自己去印证。基础弱的班就降低难度，只问第一个问题。 Part Ⅱ While-reading 读中活动（约 15 分钟） Task 1 略读（3分钟）——找两段大意 快速读，别逐字抠，填完就举手： The text mainly tells us the serious ①__________ along the Li River and the ②__________ that the government has taken. Task 2 扫读（5分钟）——判断对错 读完全文判断T/F，在原文里划出依据句。 (1) Every year a great many Chinese and foreign tourists visit the Li River. (2) Workers on tour boats poured cooking waste straight into the river. (3) All the factories along the river were closed at once. (4) Under the new rule, top officials are made responsible for river water quality. (5) China"s waterways have already become completely clean. ⏱ 阅读技巧提醒：看到all / already completely这种绝对词要警惕——原文通常没说得这么满，高考阅读最爱在这里设坑。 Task 3 细读（7分钟）——回答问题 (1) As tourism grew, what other two things also grew and made the river dirtier? (2) The local government did a lot to fix the problem. Write down at least THREE measures. (3) What is the "River Chief System"? Why does the writer think it works? Part Ⅲ 结构分析（约 8 分钟） Task 1 文章是怎么分段的？ 把每段和它的作用连起来。注意右边选项打乱了顺序，别按行对号入座。 Para. Job（选项已打乱） Para 1 ( ) c. The pollution problems in detail Para 2 ( ) a. More long-term measures (the River Chief System, media, etc.) Para 3 ( ) d. The first group of measures taken Para 4 ( ) b. Bring up the topic — the Li River and its pollution Task 2 画思维导图：污染从哪儿来？ 中间写CAUSES，往外至少画四个分支。老师先在黑板上示范一个： tourists → throw rubbish; tour boats → pour cooking oil; people → more household waste; factories → more industrial waste Task 3 再画一张：政府做了什么？ 中间写MEASURES，往外至少五个分支。时间不够就只画这张，另一张课后补。示范： water pipes built; polluting factories moved/closed; new rules + fines; TV/newspaper ads; River Chief System Task 4 写作框架（以后环保作文直接套） 以后写环境类报道，就按这个四段来： Para. What to write Para 1 Lead-in: name the issue and where it happens. Para 2 Causes and their effects. Para 3 Measures already taken (be specific — avoid "some measures"). Para 4 Evaluation and future actions. Part Ⅳ Writing (17 min) Step 1 选个你身边的话题 从下面挑一个，或者自己选：校园外卖盒 / 冬天雾霾 / 垃圾分类 / 学校里水电浪费。写之前先在脑子里过一遍这几个问题：（基础差的班统一选“校园外卖盒”，别让他们自己选，免得跑题） • 问题是什么？哪儿最严重？ • 为什么会这样？谁的责任？ • 已经做了什么？管用吗？ • 还能怎么做？ Step 2 可用句型（直接抄进作文也行） Function Sentence patterns Raising the issue ... has become a serious problem around us. / It is now affecting... Stating causes This is mainly because... / ... plays a big part in it. Describing effects It does great harm to... / As a result, ... Listing measures Luckily, action has been taken. / The government has made rules to... Looking ahead Thanks to these steps, things are getting better. / However, more effort is still needed. ★ 时态敲黑板：说“已经采取的措施”用has / have done；说过去某次具体动作（比如2020年开了个会）才用did。上次作文这错了一堆，这次注意。 Step 3 动笔写（12分钟） 按四段框架写，100词左右。写完自己先查一遍拼写和标点。老师巡视时重点盯：连接词有没有加、现在完成时用对没。 Step 4 同桌互改（3分钟）——按下面五条打分 和同桌交换作文，每条满分2分（总共10分），再写一条具体的修改建议。别光写“good”，要指出哪里可以改。 Item Score Mark ① Structure: four paragraphs (problem → causes → measures → outlook) 2 ② Cause/effect: at least one linking word used 2 ③ Tense: present perfect used for measures already taken 2 ④ Measures: at least two concrete measures listed 2 ⑤ Word count: 90–150 words 2 Total 10 给同桌的一条建议：________________________________________ Step 5 根据同桌意见改2分钟；写得好的我下课投影给大家看。 【Homework 课后作业】 1. 把课上写的报道改一改，扩到120词左右，抄在作文本上，下周一交； 2. 采访1-2个同学或家里人，问问他们对“校园外卖盒问题”怎么看，整理成3条中文要点，下节课上来做1分钟口头分享； 3. （选做）从课本词汇表里挑5个环保相关的词，各造一个句子。 参考答案与解析 课前小测（学情诊断）参考答案 Diagnosis 1： (1) because (2) As a result (3) Thanks to Diagnosis 2： took → has taken（since加过去时间点，主句要用现在完成时，表从那时候到现在一直持续）。 Diagnosis 3： 开放题，能写出2个就行，比如：plastic waste / smog / waste sorting / wasted food in canteen。 Part Ⅰ Activity 1： 1—b 2—a 3—d 4—c 5—e Activity 2： 参考思路——游客多了扔垃圾、游船排油；沿岸人口和工厂也多了，废水跟着涨。政府、游客、船家、工厂都跑不掉。 Part Ⅱ Task 1： ① problems / pollution ② measures Task 2： (1) T (2) T (3) F (4) T (5) F 讲题提醒： (3) 原文是“dozens of polluting businesses were moved or closed”，不是all factories were closed at once——以偏概全，高考常考。 (5) 原文是“are heading towards a clean and sustainable future”，是“正走向”，不是“已经完全干净了”。 Task 3 参考答案： (1) The local population grew, and the number of enterprises rose, so there was more household and industrial waste. (2) ① 污水处理和垃圾收集改进了；② 几十家污染工厂搬的搬、关的关；③ 出台了新的垃圾处理规定，违规要罚款；④ 用媒体做宣传。（任写三条就行） (3) 就是senior officials每人负责一段河道。管用是因为每个人都有明确的责任，没人能甩锅。 Part Ⅲ Task 1： Para 1—b；Para 2—c；Para 3—d；Para 4—a Task 2 思维导图参考分支： tourists: rubbish on banks; tour boats: cooking oil into water; local people: more household waste; factories: industrial waste. Task 3 思维导图参考分支： pipes & treatment built; polluting businesses moved/closed; new rules + fines; TV/newspaper campaigns; River Chief System. Part Ⅳ 参考范文 （话题：学校周边外卖塑料盒） Plastic takeaway boxes have become a real problem near our school. Every day, lots of empty boxes are thrown on the street after lunch, and they do great harm to the neighbourhood. This is mainly because students are too busy to cook, so they order takeaway every day. The shops nearby give out plastic boxes by default. As a result, a mountain of plastic waste is produced each day. Luckily, action has been taken. The school dining hall has lowered its price, and several shops now offer paper boxes for a little extra money. Our school has also put up posters to ask us to bring our own lunch boxes. Thanks to these steps, the street is getting cleaner. However, more effort is still needed — only when we stop using plastic boxes for good can we see a truly green school. ⏱ 范文旁批（叫学生在自己作文里也把这些地方圈出来）： Para1 点题，开门见山说问题在哪儿。 Para2 用了because / As a result把因果串起来，不是孤立罗列。 Para3 用了action has been taken / has put up（现在完成时！），措施写得具体，不说空话。 Para4 用了Thanks to / However收尾，最后Only when倒装加分。 【学生初稿常见毛病】别写成这样： × The plastic boxes are bad. We must stop using them. It is important to protect our environment.（全是口号，没有原因和具体措施） × The government took action since 2020.（时态错，应该用has taken） × There are many problems. The river is dirty. The air is bad.（没连接词，流水账） 附录：教师版思维导图（可直接投影或板书用） CAUSES（污染来源） 分支 要点 Tourists millions of visitors; litter on banks; more tour boats Tour boats cooking oil / kitchen waste poured directly into the river Local people population grew → more household waste Factories enterprises increased → industrial waste not properly treated MEASURES（治理措施） 分支 要点 Infrastructure wastewater treatment plants; household waste collection & transport Businesses dozens of polluting factories moved or closed Rules & fines new regulations on waste disposal; heavy fines for law-breakers Public awareness TV / newspaper campaigns Long-term system River Chief System — senior officials personally responsible 原创声明 本人声明：本文属本人原创作品，著作权授予北京今日学易科技有限公司、中学学科网独家所有，本人保留署名权。本文未粘贴任何其他网站 Logo、二维码、QQ / 微信 / 公众号等引流信息。 学科网（北京）股份有限公司 $
