内容正文:
《Unit 4 Safety first》教案(3课时)-2026-2027学年译林版(三起)(新版)小学英语五年级上册
一、学情分析
五年级学生已经积累两年多的英语学习经验,能够听懂、认读简单对话,掌握部分行为类动词,具备基础的情景问答能力。学生在校园生活中接触楼梯、体育课、泳池等真实安全场景,对安全行为有生活认知,但缺少用英语表达安全建议的语言储备。本单元核心语法should/shouldn’t属于全新语法点,学生容易忽略情态动词后接动词原形这一规则。该学段学生乐于图片观察、情景演绎、案例讨论,具备小组合作学习能力,但在连贯输出完整英语建议语句时会存在卡顿,需要教师搭建句式支架,降低语言输出难度。
二、教材分析
本单元主题为Safety first安全第一,教材围绕校园、体育课、泳池多个真实生活场景展开,板块包含Story time、Cartoon time、Sound time等。Story time以校园体育课、楼梯通行作为载体,呈现should、shouldn’t核心句型,学习push、pull、jump、warm up等行为词汇,教会学生用英语给出安全劝告。Cartoon time借助游泳小故事复现单元语法,拓展hurt、swimming pool等词汇。Sound time落实字母组合gr发音/ɡr/。整套教材将语言知识与生命安全教育融合,语言学习服务于真实生活交际,引导学生用英语谈论安全规则,落实学用结合,是语言能力与育人价值相结合的单元内容。

生:They are on the stairs. They are on the playground.
师:Great. When we are at school, we need to keep safe. Today we will learn Unit4 Safety first. 板书课题Safety first,带领学生齐读课题,讲解safety是名词,表示安全,safe是形容词安全的。
师:What things are not safe at school? Please look at the pictures in our book.
学生观察教材插图,自由口头说一说图片里看到的危险行为。
设计意图:依托教材插图创设校园真实情境,引出单元主题,激活学生已有的生活经验,自然导入新课学习。
词汇初步感知
教师出示教材Story time中出现的行为图片,依次教学单词push、pull、jump、warm up、stairs。教师结合动作示范,带领学生认读单词,板书单词。
师:Look at the picture. What is he doing? He is pushing others. Read after me push.
生:push。
师:What about this one? He pulls his classmate’s clothes. Read pull.
生:pull。
师:When we have PE class, we should warm up first. Warm up,热身。
学生跟着教师做热身动作朗读短语warm up。
师:Look,these are stairs. We walk on stairs. Read stairs.
生:stairs。
教师把单词和对应的教材图片一一对应,让学生看图识词,完成词汇初步输入。

师:Open your English book, turn to the Story time page. Now let’s listen to the dialogue of Story time. Think about one question:What should we do and what shouldn’t we do at school and in PE class?
播放教材Story time录音,学生边看课本插图和课文文字边听录音。听完录音之后,教师抛出问题,组织学生尝试回答。
师:Who can tell me your answer? What shouldn’t we do on the stairs?

第一部分研读楼梯场景文本:
教材原文:It’s time for PE. Let’s go to the sports ground. You shouldn’t run on the stairs. It’s not safe. We should also keep to the right. And we shouldn’t jump from the stairs.
师:Boys and girls,look at our book. It’s time for PE,翻译为该上体育课了。同学们要前往操场,途中要经过楼梯。请大家找一找句子里面should和shouldn’t。
学生在课本上圈画should、shouldn’t。
教师进行语法讲解:should意思是应该,shouldn’t=should not,意思是不应该。它们属于情态动词,后面必须加上动词原形,没有人称变化。举例,We should keep… keep使用原形;We shouldn’t run… run使用原形,这是本单元最重要的规则,大家在书上做好标记。
师问:Why shouldn’t we run or jump from the stairs?
生:Because it’s not safe.
教师带领学生分角色朗读这一部分对话。
第二部分研读体育课场景教材原文:
教材原文:How can we keep safe in PE class? We should warm up first. We shouldn’t push others. You shouldn’t pull his clothes, Mike. You may hurt him. I’m sorry.
师:Now we arrive at the sports ground. The big question in our book is How can we keep safe in PE class? 我们如何在体育课保证安全?请大家默读课本这一小段,找出体育课上我们应该做什么,不应该做什么。
学生默读课文,勾画关键语句。
师:What should we do first in PE class?
生:We should warm up first.
师:Yes,warm up first,先热身。What shouldn’t we do?
生:We shouldn’t push others. We shouldn’t pull others’ clothes.
师:Why shouldn’t we pull clothes? Look at the sentence “You may hurt him.” hurt意思是使受伤,你可能会弄伤他。
教师结合课本当中Mike拉扯同学衣服的插图进行案例分析,引导学生理解该行为带来的危险后果。
师:If you pull your deskmate’s clothes in PE class, what will happen?
生:He may fall down and hurt himself.
学生跟读本段课文,教师纠正学生单词发音,重点提醒should后动词使用原形。
课文跟读与角色朗读

师:What should we do on the stairs?
学生集体回答:We should keep to the right.
师:What shouldn’t we do in PE class?
生:We shouldn’t push others.
教师出示表格,表格分为Should do、Shouldn’t do两栏,引导学生结合课文内容,口头梳理课本里面的安全行为,口头完成表格内容梳理。
设计意图:依托教材文本,把课文信息转化为表格,帮助学生梳理文本信息,强化should / shouldn’t句型记忆。
第2课时 Cartoon time 新授课

学生完整朗读Story time与Cartoon time两篇教材文本,开展小组齐读、男女生分读。教师针对学生高频易错点进行点拨,重点指出学生容易出现的语法错误,比如You should warming up这种错误,再次强调should后接动词原形。
单元句式结构化梳理

should do:warm up first;keep to the right;listen to others
shouldn’t do:run on the stairs;jump from stairs;push others;pull clothes;swim in the park
学生看着思维导图,口头进行连贯表达,把课本碎片化的句子整合起来。

师:Now work in groups. Talk about safety rules in our school. Use “You should… You shouldn’t…”,参考我们课本Story time中学到的内容。
小组开展讨论,教师在教室巡回,帮助学生梳理句子,提示学生参考课本当中的词汇句型。讨论结束后邀请小组代表做口头汇报。
生示例:You should keep to the right on stairs. You shouldn’t push your classmates in PE class. You should warm up before sports.
六、小结
