This unit is about our earth and green life. Who can tell me, what does “going green” mean?生1：Going green means protecting our earth.生2：We should save resources.师：Perfect! Going green means living an eco‑friendly life, protecting our earth. In this unit, we learned many environment problems and green actions. Now let’s think, what environment problems do we know?生：global warming, pollute, waste water, cut down trees.师板书以上环境问题词汇，黑板绘制简易表格，表格分为两列：Environment problems（环境问题）、Green actions（环保行动）。师：Now work together, recall what green actions we can do to protect our earth. Let’s fill in this table together.教师引导学生回忆Lesson1‑Lesson4内容，学生举手作答，教师同步把plant trees, save energy, reuse and recycle, use less plastic bags, save water等短语填写表格，带领全班齐读表格当中全部词汇短语。设计意图：以单元主题开启复习课堂，借助表格将单元词汇按照问题、行动两大维度归类，唤醒学生旧知，搭建语言支架，改变零散记忆词汇的模式，为本课对话文本学习做好语言储备。师：Great job. These are the key words we learned in Unit4. When we see these problems, we will give advice. We often use “should” and “shouldn’t”. Now open your textbooks, turn to Unit review page. Today we will study the Look, read and talk dialogue.（二）Look, read and talk核心对话文本精讲学习教师出示教材Look, read and talk完整对话文本：Look! Our earth is getting warmer and warmer.Yes. Global warming is a big problem. What should we do?We should plant more trees. Trees can help cool the earth.What else should we do?We should save energy and water. We shouldn’t waste things.And we should reuse and recycle. We shouldn’t use too many plastic bags.Good ideas. Small things can make a big difference.Yes. Let’s start with small things in our daily life.师：Please look at the dialogue on your book. First, I will read the whole dialogue slowly, please listen carefully to my pronunciation and intonation.教师完整范读对话一遍。师：Now look at the first sentence：Look! Our earth is getting warmer and warmer. Boys and girls, pay attention to this structure “warmer and warmer”. What’s its meaning?生：越来越暖。师：Excellent！“比较级+and+比较级”，表示“越来越……”。warm的比较级是warmer，warmer and warmer就是越来越暖和。我们还可以学类似表达taller and taller，越来越高。“is getting”在这里表示正在变得，描述事物正在发生变化。Who can tell me, what is the big problem in the dialogue?生：Global warming.师：Yes, global warming全球变暖，这是Lesson1当中的核心话题。Now look at the question：What should we do? 这个句型用来询问我们应该做些什么，用来征求解决问题的建议。师板书核心句型：‑What should we do?‑We should…师：“should”是情态动词，后面要直接加上动词原形，表示“应该”，用来提出建议。Now follow me to read this sentence together：What should we do?全班学生齐读。师：What is the first suggestion in the dialogue? Who can read the answer for us?生读：We should plant more trees. Trees can help cool the earth.师：Well done. plant more trees多种树；cool the earth帮助地球降温。Why should we plant more trees?生：Because trees can help cool the earth.师：Now look at next round of dialogue：What else should we do? We should save energy and water. We shouldn’t waste things.师：What else should we do? “what else”意思是“还有别的什么”，用于追问其他建议。Please watch this word “shouldn’t”. What is its full form?生：should not。师：Right，shouldn’t = should not，表示“不应该”，用来提出否定建议，后面同样接动词原形。We should…我们应该做；We shouldn’t…我们不应该做。save energy节约能源，save water节约用水，waste things浪费东西。师带领学生齐读短语save energy, save water, shouldn’t waste things。师提问：What should we do? What shouldn’t we do? Please answer me in English.生：We should save energy and water. We shouldn’t waste things.师：Now look at the next sentences：And we should reuse and recycle. We shouldn’t use too many plastic bags.师：reuse重复利用，recycle回收利用，这两个是Lesson2绿色生活的重点短语。too many用来修饰可数名词复数，too many plastic bags太多塑料袋。师：Now I want you to think. Why shouldn’t we use too many plastic bags?生：Because plastic bags are bad for our earth.师：Now look at the last two sentences：Good ideas. Small things can make a big difference. Yes. Let’s start with small things in our daily life.师：“Small things can make a big difference.”是本单元重要语句，意思是小事也能产生很大影响。make a big difference产生很大作用、带来很大改变。start with small things从身边小事做起，呼应Lesson4课文主题。in our daily life在我们的日常生活当中。师：Please circle these key phrases and sentences in your books：warmer and warmer, global warming, plant more trees, save energy and water, reuse and recycle, make a big difference, start with small things。同时标记should / shouldn’t，提醒学生should、shouldn’t后面都接动词原形。设计意图：逐句精讲教材原生对话文本，针对比较级结构、情态动词should / shouldn’t、核心问答句型、单元重点短语进行细致拆解，依托教材原句开展师问生答，引导学生从对话文本当中抓取环境问题与环保建议信息，落实对话文本理解，夯实本课语言基础。（三）对话分层朗读操练师：Now we understand every sentence of this dialogue. Let’s do reading practice step by step.第一步，教师分句领读，学生逐句跟读，重点纠正global warming、reuse、recycle发音。师：Pay attention to “recycle”, read after me, re‑cy‑cle.全班跟读。第二步，全班齐读完整对话两遍。第三步，男女分角色朗读，男生负责提出问题，女生读出建议，完成一轮之后互换角色再次朗读。师：Boys read the questions, girls read the advice. Ready, go.一轮结束后，师：Now change roles, girls ask questions, boys give advice.第四步，小组内部分角色朗读。四人小组分配对话角色，小组内朗读对话，教师巡视课堂，走到各个小组，倾听学生朗读，提醒学生注意should后面动词使用原形，注意语句停顿。师：In your group, take turns to read the dialogue. Try your best to read fluently.小组练习结束，教师邀请2‑3组学生起立，展示分角色朗读教材对话。师：Which group would like to show your reading?师：Very good. Now let’s do fill‑in‑the‑blanks practice. I give you incomplete dialogue sentences, you fill in the missing words orally.课件出示挖空对话文本：A: Look! Our earth is getting ____ and ____.B: Yes. ____ is a big problem. What ____ we do?A: We ____ plant more trees. Trees can help cool the earth.B: What else should we do?A: We should save ____ and water. We ____ waste things.B: And we should ____ and recycle.
