《The earth is heating up》教案(2课时)-2026-2027学年冀教版(三起)(新版)小学英语六年级上册
1、 教学背景
六年级学生已经具备一定英语听说读写基础,接触过一般将来时will,掌握现在进行时基本结构。本课属于人与自然主题语境,围绕全球变暖展开,学生在科学课上已经简单了解地球变暖相关常识,具备一定生活认知,但学生对英语环境类词汇、may表推测的用法接触较少。班级学生语言水平存在分层,部分学生可以流畅进行简单对话,部分学生长句认读、理解will/may将来表达存在困难。学生对环保话题兴趣较高,能够结合生活实例参与课堂讨论,适合依托课文对话,将语言学习与环境认知相结合,落实学科育人。
2、 教材分析
本课是冀教版(三起)新版六年级上册Unit4《Going green》第一课,单元主题为绿色环保生活,属于“人与自然”主题语境,本单元从认识地球变暖环境问题切入,逐步过渡到绿色生活方式的学习与实践。本课主板块Look, listen and say是情景对话,课文原文:
The earth is heating up.
Yes.
In the next hundred years, the temperature of the earth may go up about six degrees.
The earth will go through big changes.
Will it be hard for people to grow food?
For sure.
Some plants and animals will disappear.
Can we find doctors to help?
We are all doctors. We need to live a green life.
语篇以对话形式介绍地球正在变暖这一现状,借助may、will描述未来百年地球温度上升、环境发生巨大改变、粮食种植变难、部分动植物消失等可能发生的后果,最后点明每个人都是地球的“医生”,我们需要践行绿色生活方式,引出单元主题Going green。
本课核心词汇:earth, heat up, temperature, hundred, degree, go through, change, hard, disappear, green life;重点短语:heat up, go up, go through, live a green life;核心语法:现在进行时描述正在发生的现状;will表达将来会发生的事情;may表达将来可能发生的事情。教材配套Read, write and say板块,围绕课文主题设置语段填空练习,巩固本课词汇与时态,为本单元后续学习reduce、reuse、recycle环保原则做好铺垫。

5、 教学过程
第一课时(词汇感知、课文听读理解,处理Look, listen and say主对话板块)
1. 课堂导入,主题激活
教师展示两组图片,一组是蔚蓝健康的地球,一组是地球升温、冰川融化的示意图。
师:Look at these two pictures. What can you see?
生:This is the earth. The earth is not good.
师:Yes, this is our earth. 板书单词earth,带领学生拼读,讲解词义“地球”。We live on the earth. 引导学生跟读句子。
师:Look, something is wrong with our earth. What is happening to it? 板书课题 Lesson1 The earth is heating up.,领读课题,讲解短语heat up,heating up是现在进行时形式,含义“升温、变暖”。
师:Have you learned about this in your science class? What bad things will happen when the earth gets warmer? Please share your ideas.
生1:Ice will melt.
生2:Animals will have no home.
师:Good ideas. Today we will learn a dialogue about our earth, to know what will happen if the earth is heating up.
设计意图:借助图片,联系学生科学课已有认知,引出课题与核心生词earth、heat up,建立生活经验与文本主题的联系,激发学生阅读课文的兴趣。
2. 新知词汇学习,扫清阅读障碍
教师结合课文语境,依次呈现本课重点词汇短语,结合例句开展师生问答,扫清阅读障碍。
师:Now let’s learn new words for our text. First, temperature.板书temperature,领读,词义“温度”。When the earth is heating up, its temperature goes up.板书短语go up,“上升”。

师:disappear,消失。If the earth becomes too hot, some plants and animals will disappear.教师借助简单示意图帮助学生理解词义。
师:green life,绿色环保的生活;live a green life,过绿色环保的生活。
师:Now I will ask you some simple questions to check. If temperature goes up, is it cold or hot?
生:Hot.
师:If animals disappear, can we see them?
生:No.
设计意图:结合课文原句语境学习词汇,搭配简单问答巩固词义,提前突破长难单词,降低后续课文阅读理解难度,避免孤立记忆单词。
3. 初听课文对话,整体感知语篇
师:Open your textbook, turn to Look, listen and say. This is our main dialogue. Let’s listen to the audio for the first time, please listen carefully and answer two simple questions:①What is the problem of the earth? ②What should we do?
播放课文录音,学生看着课本听录音。
师:OK,stop. Who wants to share your answers?
生1:The earth is heating up.
生2:We need to live a green life.
师:Perfect. That is the main idea of this dialogue. Now we will listen to the audio a second time. Please try to find:What may and will happen to the earth?
二次播放录音。
师:What changes will the earth face? Let’s sort them out.教师板书信息梳理表格,引导学生记录听力获取信息。
Present problem(现状)
What may happen(可能发生‑may)
What will happen(将会发生‑will)
Our idea(我们的做法)
设计意图:分层两次听录音,从整体大意到细节信息,训练学生听力抓取关键信息能力;表格搭建文本信息框架,区分may与will,降低将来时文本理解难度。
4. 逐句精讲课文对话,解析文本细节
教师带领学生逐句研读教材原文,依托课本对话,师问生答推进,解析时态、短语、句子含义。
师:Please read the first sentence together:The earth is heating up. 提问:What tense is this sentence?
生:现在进行时。
师:Right,be + doing,is heating up,描述地球此刻正在变暖这个正在发生的现状,填入表格Present problem一栏:The earth is heating up。
师:Next sentence:Yes. In the next hundred years, the temperature of the earth may go up about six degrees.
师:In the next hundred years是什么意思?
生:在接下来一百年里。
师:may go up,may表示“可能”,这是未来有可能发生,但不一定百分百发生的事。未来一百年,地球温度可能会上升大约六度。这是may引导的推测,填入表格may一栏。
师:Next:The earth will go through big changes. 提问:这里用will,what does will mean?
生:将会。
师:will表示将来将会发生。go through big changes,经历巨大的变化。地球将会经历巨大的变化,属于确定将会发生的结果,填入will一栏。
师:Now look at this question:Will it be hard for people to grow food? 这是will引导的一般将来时一般疑问句。What’s the answer?
生:For sure.
师:For sure意为“肯定、毫无疑问”。提问:What does “Will it be hard for people to grow food?” mean?
生:人们种植粮食会变得很困难吗?
师:Yes,答案是For sure,肯定会。种植粮食将会变得十分艰难,这也是将会发生的后果,填入will一栏。
师:Next sentence:Some plants and animals will disappear. 提问:What will disappear?
生:Some plants and animals.
师:Some动植物将会消失。地球变暖,生存环境被破坏,部分动植物就会消失不见,继续填入will一栏。
师:Now look the dialogue:Can we find doctors to help?
师:同学们想一想,这里的doctors是医院看病的医生吗?
生:不是。
师:Good question。Read the reply:We are all doctors. We need to live a green life.
师:这里把我们比作地球的医生,每一个人都可以拯救地球。live a green life,过绿色环保的生活。这就是文本给出的解决方向,填入Our idea一栏。
完整表格全部填充完毕,教师带领学生完整浏览表格,梳理整篇对话逻辑:地球正在变暖→未来可能、将会出现的各类环境恶果→人人都要践行绿色生活。
设计意图:逐句紧扣教材原文讲解,通过连续师生问答解析句子语义,重点辨析现在进行时、may、will不同用法,表格可视化梳理整篇对话逻辑,突破本课语法难点,理清文本内在因果关系。
5. 跟读课文,分层朗读训练
师:Now let’s follow the audio sentence by sentence. Pay attention to pronunciation and intonation.
播放音频,学生逐句跟读课文对话。
师:Now we do group reading. Group one reads the first speaker’s lines, Group two reads the second speaker’s lines. Let’s read the full dialogue.
学生分组分角色齐读整篇对话。
师:Who wants to read the dialogue in pairs in front of class? You may look at your book.
邀请2‑3组学生分角色朗读课文,教师及时纠正长单词发音、语句停顿。
设计意图:模仿录音跟读,分组分角色朗读,夯实课文朗读,内化对话语言,为第二课时语言输出做好铺垫。

设计意图:迁移课文语言框架,把课文知识转化为学生可以交际使用的语言,完成语言从输入到简单输出,落实本课语言能力目标。
4. 文本对比辨析,突破语法难点
教师板书三组句子,结合课文原句,引导学生对比辨析时态。
1 The earth is heating up.(现在进行时,描述现在正在发生)
2 The temperature may go up about six degrees.(may+动词原形,将来可能发生)
3 Some plants and animals will disappear.(will+动词原形,将来将会发生)
师:Please look at these three sentences from our textbook. Tell me their differences.
生:第一句讲现在,may是可能,will是将会。
师:That’s right。第一句is doing,现在进行时,讲此刻正在发生的现状。may和will后面都直接加动词原形,描述未来。may表示事情有发生的可能性,但不确定;will表示事情将会发生,是较为确定的结果。
师:Now look at two questions from the text:
Will it be hard for people to grow food?(will引导一般将来时一般疑问句)
师:在will引导的问句中,will放到句子开头,后面动词使用原形。
师:Please go back to our dialogue, mark all sentences with may, will and is‑doing in your book. Students read them out one by one.
学生在课本对话中标出对应句子,轮流读出句子。
设计意图:针对本课语法难点做对比辨析,依托课文原句,帮助学生理清现在进行时、may、will三者用法,化解教学难点,加深学生对文本语法的理解。
5. 依托表格支架,口头复述课文
师:Now please try to retell the whole dialogue without reading the textbook. You can use our chart on the blackboard as your hint。
给予学生准备时间,学生借助板书表格复述课文故事。
生:The earth is heating up. In the next hundred years, the temperature may go up about six degrees. The earth will go through big changes. It will be hard for people to grow food. Some plants and animals will disappear. We are all doctors. We need to live a green life.
教师针对复述内容做简单纠错引导。
师:Wonderful. You can also try to say one bad thing that the heating earth brings, and one thing we should do.
邀请2‑3名学生简短口头表达自己的观点。
设计意图:复述课文,内化文本内容;引导简单观点输出,呼应单元Going green主题,实现语言输出。
6、 课堂小结
两课时整体小结:本节课我们学习Unit4 Lesson1《The earth is heating up》。通过对话学习,我们读懂地球正在变暖这一环境现状,了解未来地球温度可能上升,地球将会经历巨大变化,粮食种植变得困难,部分动植物将会消失等一系列后果。我们掌握earth、temperature、hundred、degree、disappear等核心词汇,掌握heat up、go up、go through、live a green life重点短语;分清现在进行时描述当下现状,may表达将来可能发生的事情,will表达将来将会发生的事情。课文告诉我们,我们每个人都是地球的“医生”,我们应当践行绿色环保的生活方式,保护我们赖以生存的地球家园。
