Accept 【2c】influence　quality　traffic　creative　worse　challenges 思路点拨：2c 主线：AI 影响（influence）生活质量（quality）→ 交通（traffic）→ 教育 → 更有创造性（creative）的任务 → 变好还是变坏（worse）→ 取决于（depends on）如何使用。 （三）Step 3 3a 读 Mandy 的未来梦想 Pre-writing：What will you do in the future? Imagine how you will live in the future——Transportation 交通运输 / Work place 工作地方 / Environment 环境 / Daily Life 日常生活 / Education 教育 / Housing 居住。Look at the pictures and predict: What will Mandy do in the future? What will her life be like then? Match the main ideas with each paragraph：Part 1 Dream job and activities / Part 2 Place to live and life activities / Part 3 Ways to make dreams come true。 课文原文（课本 p.69 逐字）： My Dreams for the Future——What will my life be like in 20 years? It's not an easy question, but here are a few of my predictions. I love art, so I think I will become an artist. I want to study art in France, and then I will visit all the famous art museums. I will learn a lot about different artists and their works of art, and I will create my own too. As an artist, I will live in the countryside and stay close to nature. There will be flowers and plants around my home. Life there will give me good ideas for making art. At the weekend, I will invite friends to come over and have fun together. I believe these dreams will come true as long as I study hard and keep on trying. 图2　3a-3b Mandy 的梦想信息表 【3a 表格】Future job—Artist；Place to live—in the countryside（stay close to nature）；Free time activity—invite friends to come over and have fun together；How to make dreams come true—Study hard and keep on trying 思路点拨：开头设问自答（What will my life be like in 20 years?）是未来畅想类作文的经典开头。 （四）Step 4 3b-3c 写“20 年后的我” 写作指导：体裁——个人未来畅想类短文（记叙与说明结合）；人称——第一人称（I/My）；时态——主体用一般将来时（will+动词原形）。 结构分析：Beginning 引入主题（What will my life be like in 20 years? It's not an easy question...）→ Body 分述（Future job: I love ..., so I think I will become ...；Study: I want to do sth in ..., and then I will ...；Place to live: As a/an ..., I will live in ... and stay close to ...；Life activities: At the weekend, I will ...）→ Ending 实现途径（I believe these dreams will come true as long as I study hard and keep on trying.） 3b Complete the table about your dreams.（课本 p.69）Future job / Place to live / Free time activity / How to make dreams come true Sample 1（篮球梦）：What will my life be like in 20 years? It's not an easy question. I love sports, so I think I will become a basketball player. I want to play for a great team, and then I will make many fans happy. As a player, I will live in a big city and stay close to my team. There will be a big gym near my home. I will practice there every day. In my free time, I will watch games with my family or help teach children how to play basketball. I believe these dreams will come true as long as I practice hard and never give up. Sample 2（机器人工程师）：What will my future be like? I have some exciting ideas. Because I am deeply interested in technology and helping people, I want to become a robot engineer. I plan to study engineering at university, and then I will design helpful service robots. To find inspiration, I hope to live in a modern and green city. My home will be quiet, with a small garden full of flowers. This peaceful place will help me think clearly. After work, I will not only read science books but also join a music club to relax. I will study hard and keep learning new things. By doing these, I'm sure I can achieve my dreams. 图3　三段式结构：Beginning-Body-Ending 思路点拨：Body 段每句一个信息点：职业→学习→居住→周末活动，四句一段正好。 （五）Step 5 随堂检测 当堂完成，答案见各题下方。 1. He ____________ (mention) a plan to learn German last week. 答案：mentioned（last week 用过去式） 2. It is important for young students to ____________ (develop) skills that will be valuable in the future. 答案：develop 3. Will AI make our life better or ____________ (bad)? 答案：worse（比较级与 better 并列） 4. It depends on how we choose to improve and use AI to meet future _______________ (challenge). 答案：challenges（future 后用复数） 5. My home will be quiet, with a small garden ________ ______ flowers. 答案：full of（be full of 充满） 6. I believe these dreams will come true ______ ______ ______ I study hard and keep on trying. 答案：as long as 7. At the weekend, I will invite friends to ________ ________ (来访) and have fun together. 答案：come over 8. Life there will give me good ideas for ________ (make) art. 答案：making（介词 for 后接动名词） 易错提醒 注意：winner 的反义词是 loser（win→winner / lose→loser），不是 failer——fail 的名词形式是 failure。 注意：Asimov 阿西莫夫是科幻作家——他的机器人思想影响了后辈作家，influence 此处作动词用过去式。 注意：as long as 只要——引导条件状语从句，从句用一般现在时（as long as I study hard），主句用将来时。 注意：come true 不能用被动（dreams come true 不是 are come true）；come over 来访——invite friends to come over 固定搭配。 注意：valuable 是形容词（a valuable skill 宝贵的技能），名词是 value；German 首字母大写指德国人/德语。 答题技巧 否定前缀只加词不变形：impossible 不是一个 impossible 词——possible 加 im-，p 不双写。 2b 第 1、3 题用过去式（讲故事背景）；第 5 题在祈使句句首用原形 Accept。 三段对应三个 Part：职业+学习计划→居住+生活活动→实现梦想的途径。 写作自查三问：三段齐全吗？时态统一将来时吗？结尾有实现途径吗？ 第 3 题 better or ______——better 是 good 的比较级，bad 的比较级 worse 并列。 语言点归纳 开头句式：What will my life be like in 20 years? / I am deeply interested in ..., so I want to be ...； Body 句式：I love ..., so I think I will become ... / I want to do sth in ..., and then I will ... / As a/an ..., I will live in ... and stay close to ... / There will be ... around my home / At the weekend, I will ...； 结尾句式：I believe these dreams will come true as long as I study hard and keep on trying. / By doing sth, I'm sure I can achieve my dreams.； “努力”短语：keep learning / never give up / do my best / keep going。 课堂总结 本课围绕 Vocabulary in Use & 3a-3c 展开： 1. 归纳否定前缀 im-/un-/dis- 的构词规律，完成 2b-2c 两篇词汇填空； 2. 读懂 Mandy 的未来梦想：艺术家→乡下居住→周末聚会→努力学习实现； 3. 完成 3b 梦想表并仿写三段式短文“20 年后的我”； 4. 掌握 as long as 条件句、come true / come over / be full of 等写作高频表达。 第 页 共 页 学科网（北京）股份有限公司 $
