《Unit 8 Then and now》教案(3课时)-2026-2027学年译林版(三起)(新版)小学英语六年级上册 1、 学情分析 六年级学生已经积累一定英语基础,前期接触过一般过去时,掌握部分动词过去式,具备基础听说读能力,能够进行简单情景对话。本单元主题为过去与现在的变化,需要同时切换一般过去时与一般现在时,学生容易混淆两种时态动词形式,不规则动词变形记忆存在困难。学生对生活、通讯方式变迁话题有生活体验,乐于结合自身、家人真实经历表达,但连贯运用…years ago、could/couldn’t、now进行完整语段输出的能力不足,书面表达时容易出现时态混用错误。学生具备小组合作、看图提取信息的学习能力,适合借助表格、时间轴、课文文本开展对比式课堂学习。 2、 教材分析 本单元主题Then and now(过去和现在),围绕个人能力、通讯方式、生活方式的时代变化展开,单元板块包含Story time、Grammar time、Fun time、Sound time、Checkout time,以祖孙对话的课题探究为故事主线,呈现过去与现在生活的对比语篇。核心词汇围绕通讯、信息获取:then, now, ago, telephone, mobile phone, radio, newspaper, Internet, letter, email;核心语法为could/couldn’t(can过去式),…years ago过去时间标志词,一般过去时与一般现在时对比,不规则动词过去式;语篇讲述Mike采访爷爷奶奶,对比过去获取新闻、沟通交友、购物出行的方式,感悟科技带来生活改变,亲情不会改变的内涵。教材由故事理解,过渡语法归纳,再到口语操练,最后综合输出,层层递进,引导学生用英语描述变化,落实学科育人。本单元安排3课时完成教学,第1课时Story time语篇理解,第2课时Grammar time、Fun time语法操练,第3课时Sound time、Checkout time综合运用。 3、 核心素养教学目标 (1) 语言能力 1. 能听懂、认读、朗读本单元核心词汇、短语,读懂Story time完整语篇,获取文本时间、事件细节信息; 2. 掌握句型…years ago, sb could / couldn’t… Now sb can…,In the past,… Now…,能区分could/couldn’t和can/can’t,辨别…ago、now时态标志词,正确使用常见不规则动词过去式; 3. 能朗读复述课文片段,口头描述个人、家人过去与现在的变化,完成简单书面语句输出。 (2) 文化意识 了解通讯、生活方式随时代发展发生的改变,体会科技给生活带来便利,懂得时代不断进步,感悟无论生活如何改变,亲情与情感沟通始终重要,尊重不同时代的生活方式,建立热爱生活的情感。 (3) 思维品质 借助表格、时间轴对比过去、现在的信息,训练对比分析、归纳整理信息的逻辑思维;能区分过去与现在不同状态,发现时态使用规律,学会从文本中提取关键信息,进行简单推理思考。 (4) 学习能力 学会借助时间标志词判断时态,掌握“阅读—找关键词—归纳句型”的阅读策略;乐于参与小组对话、文本研读活动,主动联系生活实际运用单元语言知识,养成跟读、整理动词变形的学习习惯。 4、 教学重难点 教学重点 1. Story time课文理解、朗读;掌握通讯、变化主题核心词汇; 2. 掌握句型…years ago, sb could/couldn’t… Now sb can…,识别…ago、in the past、now时间标识; 3. 理解could是can的过去式,区分一般过去时、一般现在时基本用法。 教学难点 1. 在语境中正确切换一般过去时和一般现在时,不混淆动词形式; 2. 不规则动词过去式read‑read, write‑wrote等在句子中准确使用; 3. 结合真实生活,连贯口头描述人或者生活发生的变化。 5、 教学过程 第一课时 Story time 课时任务:学习Story time课文,掌握单元核心词汇,读懂祖孙对话课题语篇,梳理文本中爷爷、奶奶过去与现在生活方式变化,会朗读课文,理解重点句型。 1. 课堂导入,话题激趣 教师展示两组图片,一组老式电话、收音机、纸质信件,一组智能手机、网络电脑、电子邮件。 师:Look at these pictures. What can you see? 生:I can see a telephone / a mobile phone… 师:Very good. One is long long before, one is today. We can say “then” and “now”. 板书板书课题Unit8 Then and now,带读then / now。 师:What does “then” mean? 生:It means long ago, in the past. 师:Yes. “Now” means today. Boys and girls, what changes can you find between then and now? 生自由简单发言,说一说看到的不同。 师:Great. Today Mike does a project. A project about life in the past and now. 板书短语do a project,讲解project“课题”。Mike asks his grandpa and grandma many questions. Let’s go into the story。 设计意图:直观图片引出单元主题then与now,激活学生已有生活经验,引出故事背景Mike做生活变迁课题,自然导入Story time课文。 2. 初读课文,整体感知 教师播放Story time完整录音,学生看书静听。 师:Now listen carefully, try to answer one big question:What is Mike’s project about? 播放录音结束,请学生作答。 生:His project is about life in the past and now. 师:Perfect. Open your books, turn to Story time。请学生默读课文,圈出文中出现的人物。 师:Who are in this story? 生:Mike, Grandpa, Grandma. 师:Right. Mike talks with his grandparents. He wants to know changes in their life。板书单词changes,释义“变化”。 师:Please skim the text, draw two kinds of time words in the article,把表示过去、现在的时间短语画横线。 学生默读勾画,教师巡视。 师:Who can tell me which words mean “past”? 生:six years ago, thirty years ago, twenty years ago。 师:Excellent。…years ago表示……年以前,用于讲述过去,是过去时间标记。and which words mean now? 生:Now, these days。 教师板书时间标志短语,带领全班齐读,搭建时间轴简易板书,左侧写…years ago(then / in the past),右侧写now / these days,区分两大时间场景。 设计意图:听读、默读文本,训练学生获取主旨、定位文本信息能力,抓时间关键词,为本课时态对比搭建支架。 3. 分段研读课文,文本细节解析 段落一(课文开头对话) 文本原文:Hi, Grandpa and Grandma. I’m doing a project on life in the past and now. Can you tell me about the changes in your life? 师:Let’s read the first paragraph together。教师领读句子,讲解短语tell sb about sth告诉某人关于某事。 师:Why does Mike talk with grandpa and grandma? 生:Because he is doing a project about life in the past and now. 段落二:Grandpa的变化(获取新闻的方式) 文本:Thirty years ago, Grandpa listened to the radio for news. He read newspapers for news. Now he reads news on the Internet. 教师出示本部分课文,重点词汇教学radio, newspaper, Internet,教师带读三遍,纠正发音。 师:Look at this sentence “Thirty years ago, Grandpa listened to the radio for news.” Thirty years ago,三十年前,是过去,动词要用过去式。listen过去式listened;read原形read /riːd/,过去式仍然拼写read,读音变为 /red/,这个是不规则变化,请大家做好笔记。 师提问:How did Grandpa get news thirty years ago? 生:He listened to the radio and read newspapers for news. 师:Good。What about now? How does he get news now? 生:Now he reads news on the Internet. 教师在黑板简易表格填写爷爷的信息: Time Grandpa get news Thirty years ago listened to the radio, read newspapers Now reads news on the Internet 师:Please read these two sentences in groups,小组内分角色朗读爷爷的片段。 段落三:Grandma的变化(写信交友、购物) 文本:Twenty years ago, Grandma wrote letters to her friends. She made friends at school. Now she writes emails to her e‑friends. She does shopping on the Internet. 师:Twenty years ago,二十年前,同样讲述过去。重点单词letter, email, e‑friend,动词write‑wrote、make‑made不规则过去变形,板书原形和过去式,强调过去时间句子动词用过去式。 师问:What did Grandma do twenty years ago? 生:She wrote letters to her friends and made friends at school. 师:Now, what does she do? 生:Now she writes emails to her e‑friends and does shopping on the Internet. 师点拨:twenty years ago是过去,wrote、made;now是现在,主语she第三人称单数,动词write‑writes,do‑does。继续完善黑板表格,补充奶奶内容。 段落四:Mike自身能力变化 文本:Six years ago, Mike could read and draw, but he could not write. Now he can do many things. 师:Look here,could是can的过去式,表示“过去能够”;could not = couldn’t,过去不能够。 师:Six years ago,六年前,Mike很小。What could Mike do six years ago? 生:He could read and draw. 师:What couldn’t he do? 生:He could not write. 师:Now, what can Mike do? 生:Now he can do many things. 师:“but”在这里起到转折作用,过去会做某事,但是不会做另一件事。请同学们齐读句子,体会but转折含义。 继续表格补充Mike的能力变化。 段落五课文结尾感悟 文本:With new technology, life becomes easier and faster. But one thing never changes: the love in the family. 师讲解technology科技。师提问:What becomes easier and faster? 生:Life becomes easier and faster with new technology. 师:What never changes? 生:The love in the family. 师:Yes. Technology changes our life, but family love is always there。 设计意图:逐段解析课文原文,依托教材文本,师问生答逐层挖掘细节,借助表格梳理人物过去与现在,重点突破词汇、不规则动词、could/couldn’t句型,把语法知识融入课文语境,不脱离文本单独讲语法。 4. 课文跟读、朗读巩固 播放完整课文录音,学生逐句跟读,注意过去式读音,尤其read /red/。之后开展分层朗读,全班齐读、小组分角色朗读Mike、Grandpa、Grandma对话。 师:Now, let’s read the whole story together。读完后,教师针对表格,引导学生看着表格尝试口头复述课文主要信息。 师:Who wants to try to talk about grandpa’s changes according to our table? 学生尝试口头复述片段。 5. 课时小结 师:In this lesson, we read Story time.

I couldn’t skate. now can / can’t Now I can swim. I can skate too. 师再出示另外两组课本例句,区分实义动词过去式和现在时: Thirty years ago, Grandpa listened to the radio. Now he reads news on the Internet. Twenty years ago, Grandma wrote letters. Now she writes emails. 师:Look at the verbs。过去句子动词要用过去式,now句子用动词原形或者三单形式。提醒学生重点记忆本单元不规则动词清单,板书: write‑wrote;read‑read /red/;make‑made。 师:Let’s do sentence practice。教师给出情景:五年前我会骑车,不会游泳。现在我会骑车,也会游泳。请学生口头造句。 生1:Five years ago, I could ride a bike. I couldn’t swim. Now I can ride a bike and I can swim. 师点评纠正。再进行2组口头造句训练。 设计意图:依托教材Grammar time原句,引导学生自主观察、归纳语法规则,而不是教师直接灌输,表格直观对比,把情态动词、实义动词时态变化讲清,结合口头造句巩固句型。 3.
