He writes an email to John for help. decorate v. 装饰；装潢。装饰准备：paint the wall 刷墙 / hang up the photo 挂照片 / put up some posters 张贴海报 / buy some flowers 买花 3a Read the email and find out what Zhang Peng asks his friend to do.（课本 p.19） Hi John, It was fun to decorate your room last month. I share a room with my brother. We want to decorate it too. Can you help us? Right now, the walls are blue. There are cute animals on them, but the animals look too young for us. We want to cover the animals and paint the walls light green. What do you think about the colour? On Sunday, we can meet at the paint shop near the shopping centre and choose the paint together. Then we can paint the room with my brother. I loved the brushes we used for your room. Can you bring them? After painting, could you help choose some photos to hang on the walls? Let me know what you think. Best, Zhang Peng 邮件结构标注：greeting 打招呼（Hi John）→ body 正文 → closing 结尾（Best）→ signature 署名（Zhang Peng）；收信人 To、邮件主题 Subject。 Zhang Peng 请 John 做的三件事：choose the paint 挑油漆 / bring the brush 带刷子 / hang up the photos 挂照片。 思路点拨：邮件正文四段对应“目的—现状—计划—请求”，条理清晰。 （五）Step 5 3b 排序与写作组织 3b Put the things in order to see how Zhang Peng organizes his ideas in writing.（课本 p.19） 1 ask John to help decorate the room（开门见山，表明写信目的） 2 describe how the room looks now（描述房间现状） 3 tell John about the plan for the walls（告知装饰计划） 4 ask John to meet on Sunday at the paint shop（时间、地点） 5 ask John to bring the brushes（具体请求） 6 ask John to help choose some photos to hang on the walls（具体请求） 写作组织图：decoration→main decoration idea→action→ask for help→specific requests。 图3　3b 邮件写作的六步组织顺序（课本 p.19） 思路点拨：对比你自己写信：把请求放在最前面反而显得突兀，先铺垫再请求更得体。 （六）Step 6 3c 仿写求助邮件 3c Write an email to ask a friend to help decorate your room.（课本 p.19）可求助事项：buy some flowers / make a poster / go shopping / bring a pair of scissors / buy glue / bring a brush / make paper-cuts / bring a painting ... 写作指导：体裁——求助邮件（仿写阅读邮件），内容涉及装饰计划，侧重记叙；人称时态——以第一人称为主，一般现在时和将来时为主。 结构框架：Dear ______（称呼）→ How is it going? I want to decorate... Could you give me a hand?（表明目的）→ Right now, it's...（房间现状）→ We want... We can...（装饰计划）→ Could you please...（具体请求：时间、地点、事情）→ Best, ______（结尾敬语+署名） 范文（Lily）：Hi Peter, How's everything going? I want to decorate my room this weekend. Could you give me a hand? Right now, my room looks empty. I want to buy some flowers and make a poster to brighten it up. Could you go shopping with me to choose supplies? Also, could you bring a pair of scissors and glue? We'll need them for paper cuttings. Let's meet at my house on Saturday morning. Thank you so much! I know we'll make my room amazing together. Best, Lily 图4　求助邮件写作结构框架（课本 p.19） 思路点拨：仿写时换齐四个要素：新目的、新现状、新计划、两三个具体请求。 （七）Step 7 随堂检测 当堂完成，答案见各题下方。 1. —I made a lot of food, so feel free ________ what you like. —OK. A. eat B. eats C. eating D. to eat 答案：D（feel free to do sth. 随意做某事） 2. —What do you think we should do to make our classroom cleaner? —It's important to ________ rubbish and put it into the rubbish bin. A. put up B. hurry up C. cut up D. pick up 答案：D（pick up rubbish 捡起垃圾） 3. —The fish was dead. It started to smell ________. Could you take it out now? —OK. A. bad B. badly C. good D. well 答案：A（smell 系动词后接形容词 bad） 4. —How is your leg, Maria? —The doctor said there was ________. But I will be well soon. A. anything wrong B. something wrong C. wrong anything D. wrong something 答案：B（肯定句用 something；修饰词 wrong 后置） 易错提醒 注意：scissors 恒用复数（a pair of scissors），glue 不可数；Could you please 后接动词原形。 答题技巧 先做有把握的（hunt/nod/dead），用交叉字母验证长词（community/journey）。 ①后句 keep it clean 提示是浴室；②starting to smell 提示是垃圾；④on the wall+Grandma in it 提示是照片。 ①修饰动词 feel 用副词 soon；②Your 后接名词 arrival；⑤⑥记搭配 be ready to do 与 feel free to do。 find out what he asks John to do：抓三个请求句 Can you bring them? / could you help choose some photos... 排序口诀：先目的、再现状、后计划，具体请求放最后并给出时间地点。 第 3 题 smell 是系动词（闻起来），后接形容词不接副词；第 4 题复合不定代词修饰语后置。 语言点归纳 求助邮件三要素：礼貌请求（Could you please...?）+ 具体安排（时间、地点）+ 感谢结尾（Thank you so much!）； 常用短语：give me a hand 帮我一把 / brighten it up 让它亮起来 / a pair of scissors 一把剪刀 / paper cuttings 剪纸； 人称第一人称为主，时态一般现在时+将来时。 课堂总结 本课围绕 Vocabulary in Use & 3a-3c 展开： 1. 通过字谜与释义联想掌握 hunt、nod、community 等十个新词； 2. 掌握 pack up / clean up / hang up / take out 四组动副短语搭配； 3. 读懂 Zhang Peng 的求助邮件，梳理“目的—现状—计划—请求”写作顺序； 4. 会仿写求助邮件：礼貌请求+具体安排+感谢结尾。 第 页 共 页 学科网（北京）股份有限公司 $
