Unit 7 When Disaster Strikes Period 6 Period 1 Learning Plan Learning objectives: 学习目标: By the end of this lesson, you will be able to: 1. Identify common modal verbs (can, could, should, must, have to, may, might) and their basic functions. 2. Distinguish between using modal verbs to express ability, advice, obligation, and possibility. 3. Use modal verbs correctly to complete sentences and give instructions related to disaster scenarios. 【课前预习案】 I. 回顾与思考 1. 在本单元中,你见过以下情态动词吗?请从课文中找出含有这些词的句子(写出一句即可)。 - should: _________________________________________ - can: ___________________________________________ - must: __________________________________________ - may/might: ______________________________________ 2. 你认为这些情态动词分别表达什么意思?试着连线: (1) should ______ A. 能力、可能性 (2) can ______ B. 建议、应该 (3) must ______ C. 必须、一定 (4) may/might ______ D. 可能、也许 3. 情态动词后面的动词要用什么形式?(如:原形、to do、-ing)请写出规则: ___________________________________________________ II. 试试身手 用适当的情态动词填空: 1. During a typhoon, we ______ stay away from windows. 2. You ______ help clean the streets after the earthquake if you have time. 3. I ______ speak a little English, so I can talk to foreign volunteers. 4. The weather report says it ______ rain heavily tonight. 5. For your safety, you ______ follow the evacuation instructions. --- 【课中学习案】 Step 1: 发现规律——从课文中找情态动词 1. 两人一组,快速浏览Unit 7的课文和对话,找出至少5个含有情态动词的句子,并抄录下来。 2. 全班分享找到的句子,并将它们写在黑板上。 3. 观察讨论:这些句子中的情态动词分别表达了什么含义?(是能力、建议、义务还是可能性?) Step 2: 功能学习与归纳 1. 学习情态动词的核心功能表: | 功能 | 情态动词 | 例句(结合灾害主题) | |------|----------|---------------------| | 能力 / 可能性 | can, could, may, might | We can distribute supplies. It might rain tomorrow. | | 建议 / 应该 | should, ought to, could | You should prepare an emergency kit. | | 必要 / 义务 | must, have to, need to | You must evacuate immediately. | 2. 语法规则重点: - 情态动词 + 动词原形 (如:should go, can help) - 第三人称单数不加-s (He should prepare. 不是 He should prepares.) - 构成疑问句:将情态动词提前 (Can you help? Should we leave?) Step 3: 控制性练习——巩固理解 1. 功能匹配练习: 判断下列句子中情态动词的功能。 - "You must turn off the gas." ( ) - "She can speak three languages." ( ) - "We should check our supplies." ( ) - "It may flood this weekend." ( ) (选项:A. Ability B. Advice C. Obligation D. Possibility) 2. 选词填空: 选择正确的情态动词完成句子。 - Before an earthquake, you (should/must) secure heavy furniture. - I (can/must) swim, so I can help during floods. - They (may/should) need more volunteers tomorrow. Step 4: 小组任务——制作“灾害应对指南” 1. 小组分配:每个小组选择一种灾害(地震、台风、火灾、洪水)。 2. 任务:制作一份简单的《灾害应对指南》海报,必须使用至少4个不同的情态动词。 3. 模板提示: - 准备工作 (Preparedness): 使用 should/can (建议/能力) *例句:You should prepare a flashlight.* - 发生时行动 (During the disaster): 使用 must/have to (必须) *例句:You must stay calm.* - 可能性说明 (Possibilities): 使用 may/might (可能) *例句:Phone lines might be busy.* 4. 小组合作,在海报纸上完成指南。 Step 5: 展示与反思 1. 画廊漫步: 将所有小组的海报贴在墙上。轮流观看其他小组的作品,找出他们正确使用的情态动词,并给予一个“点赞”贴纸。 2. 总结与输出: 完成“出口票”任务: - 用 should 写一条防灾建议:_________________________ - 用 must 写一条灾害发生时的必须行动:_________________________ --- 【课后巩固案】 I. 基础达标 1. 整理本课学习的情态动词功能表(包括动词、功能和1个例句)。 2. 完成练习:将5条中文的灾害应对指令翻译成英文,并使用正确的情态动词。 (1) 你应该准备一个应急包。 → ________________________________________ (2) 地震时你必须躲在坚固的桌子下。 → ________________________________________ II. 能力提升 1. 录制一段30秒的英文音频,模拟播报一条台风预警,并使用至少3个不同的情态动词(如:may, should, must)。 2. 检查你在Step 4中小组制作的海报,将使用的情态动词标注出来,并注明其功能。 III. 拓展思考 1. 比较 must 和 have to:它们都表示“必须”,但在情感上有什么细微差别?在灾害指令中,使用哪一个更合适?为什么? 2. could 既可以表示“过去的能力”,也可以表示“委婉的建议”。请分别造一个与灾害相关的句子。 答案 【课前预习案】 I. 回顾与思考 1. 示例: - should: "We should make some preparations." (Li Wei) - can: "We can clean the streets." (Wu Lin) - must: (课文直接示例可能较少,可从指令中引申:You must stay indoors.) - may/might: "It may cause more floods." (For Better Performance 部分) 2. (1)-B, (2)-A, (3)-C, (4)-D 3. 情态动词后接动词原形。 II. 试试身手 1. should / must 2. can 3. can 4. may / might 5. must 【课中学习案】 Step 3: 1. 功能匹配: - "You must turn off the gas." (C. Obligation) - "She can speak three languages." (A. Ability) - "We should check our supplies." (B. Advice) - "It may flood this weekend." (D. Possibility) 2. 选词填空: - should - can - may Step 5: (出口票答案示例) - You should have an emergency plan for your family. - You must not use the elevator during an earthquake. 【课后巩固案】 I. 基础达标 2. 翻译示例: (1) You should prepare an emergency kit. (2) You must take shelter under a strong table during an earthquake. III. 拓展思考 1. must 更多表达说话人主观认为的“必须”,带有强烈建议或命令的语气;have to 更多表达客观规则或情况要求的“必须”。在正式的灾害指令中,常用 must 以体现权威性和紧急性。 2. 示例: - 过去能力:My grandfather could build a safe shelter when he was young. - 委婉建议:You could also store some bottled water. --- 说明: 本导学案可直接复制到Word文档中使用,已优化格式便于打印分发。练习答案可供教师参考或学生自检。 学科网(北京)股份有限公司 $
