教学过程

教学准备

Step1. Before-reading (课前播放自编的歌曲:What can we do to keep our city clean? We can plant trees to keep the air clean. We can do some cleaning to keep the streets clean. We can put rubbish in the bin. We can plant trees to keep the air clean. We can put rubbish in the bin.) 【设计意图】通过自编的英文歌曲，营造轻松的学习氛围，歌曲贴近本单元主题，为接下来学习语言知识做铺垫。

1.

Look and say a.

T: Do you like pictures? S: Yes. T: Today I bring some pictures of a city in the past. Look!

What do you think of this city? S: It’s nice/beautiful/clean…

b.

T: Good. Now there’s a little different.

Is the city clean now?

S: No, it isn’t.

T: Do you like it? S: No. T: So we should keep our city clean. (Lead in the title: Unit6 Keep our city clean) 【设计意图】学生在图配乐的情境中对比城市环境的优美和不干净，在强烈的视觉冲突中初步激发学生的环保意识。由此引入本单元环保的主题，揭示课题。

Step2. While-reading 1.

Think and guess T: Look at this picture, who are they? S: Miss Li and her students. T: Yes. They live in the city we talked about before. We know the city is not clean. Guess, what questions are

they talking about? S: What makes our city dirty? / What can we do to keep our city clean? / How do we keep our city clean? /

Why do we keep our city clean? / Where is dirty? ... T: Wow, you have so many questions.

【设计意图】教师鼓励学生积极思考，预测李老师和学生们讨论的问题，发散学生的思维，提高自主学习的能力，体现“先学后教”的教学理念。

2.

Listen and answer T: Let’s listen to the tape, then tell me, what questions are they talking about?

S1: What makes our city dirty? (学习dirty,出示句子并跟读。)

S2: What can we do to keep our city clean? (出示句子并跟读，板：What makes…dirty? What can we do to…?)

【设计意图】教师改变了以往先看动画后回答问题的固定模式，学生能在倾听中搜索关键信息，在大脑中整理好语言后进行语言输出，很好地训练了学生的听的能力。同时，这也是学生的猜测得到验证的过程，能更好地激发学生的求知欲。

3.

Read and match T: First, what makes our city dirty? What problems? Try to read the sentences in groups of four and then

match the pictures. If you meet new words, you can learn from others. Now take out your paper and pictures.

(Work in groups and check the answer)

T: First, let’s focus on the air. Look at the two pictures, is the air clean?

S: No.

(Learn: air) 4.

Scene One(picture 1,2) a.

T: Everyone needs air. What makes the air dirty? S1: Smoke from cars makes the air dirty. (出示句子, 板: smoke from cars) T: Look, it’s smoke. It’s bad for us. (Learn: smoke)

S2: Black smoke from factories makes the air dirty too. (出示句子，板: black smoke from factories) T: Let’s read.

b.

T: Smoke makes the air dirty. What other places is smoke from? (出示: smoke from_______) S: Smoke from buses/taxis/trains/planes…

T: Well done. And smoke from…makes… (出示: Smoke from ______ makes______.) S: Smoke from buses/taxis/trains makes the air dirty. T: We know the first problem is “smoke”. Anything else?

【设计意图】学生围绕第一个镜头“空气污染”，聚焦到第一、二两幅图，思考烟雾还可以来自其他什么地方，由smoke到smoke from…,再到Smoke from…makes…的语言的叠加，在丰富学生表达的同时，帮助学生理解文本的内涵。

5.

Scene Two(picture 3,4) a.

T: Next, let’s focus on the streets and the river. Are they clean?

S: No. They’re dirty.

T: Yes, they’re messy and dirty. Which one is messy? S: Choose B. T: That’s it. It means messy.

(Learn: messy)

What makes the streets and the river messy and dirty? (板: messy) S: Rubbish. (板: rubbish) T: Yes. There’s a lot of rubbish. Look, the fish can’t swim, they’re dead.

(Learn: rubbish, dead, 出示: Rubbish makes…dead.)

T: Let’s read.

b.

T: What other places does rubbish make messy and dirty? (出示: Rubbish makes _________messy and dirty.) S: Rubbish makes the park/cinema/supermarket/bus stop/station/school/zoo/house/forest/lake…messy and dirty. c.

T: We can say the second problem is “Rubbish”. In fact, smoke and rubbish are harmful to us. For example,

we have no fresh air to breath, no green vegetables to eat. Anything else? You can discuss in pairs, then tell me.

S: We have no beautiful flowers/trees/parks/gardens to see/no fruit to eat/no clean schools to see/no lovely birds and fish to see/no blue sky to see…

【设计意图】学生围绕第二个镜头“垃圾污染”，聚焦到第三、四幅图，展开讨论。学生能在图片对比中理解messy,同时，思考出现垃圾的地点，以及环境污染给人们带来的危害，激发学生进行头脑风暴，激活了学生已有的知识储备。

6.

Look and think a.

T: There are some problems which make our city dirty. What can we do to keep our city clean? Do you have

any ideas? S: We can grow some flowers/plant green trees/vegetables/do some cleaning/walk to school…

T: How to solve the first problem? Look, we can… (板: take the bus and the metro, walk to school)

How do you go to school? S: I go to school…

T: I think…

(Tip1: Walking is more environmental.) T: How about this one? We can…

(Learn: move…away from, 板: move factories away from) T: Listen and read. b.

T: How to solve the second problem? Look, we can…

T: Look, it’s recyclable, it’s other waste.

(Tip2: We should classify the rubbish.)

(Learn: put rubbish in the bin, plant more trees并板书) T: Listen and read. T: The students have so many ideas. If you are Miss Li, what can you say? S: So great! / Wonderful! (跟读: Your ideas…class!)

【设计意图】教师先让学生谈谈自己关于环境污染的建议，接着，在师生互动交流中构建语言知识。针对文本中提出的问题与建议割裂开来讨论，学生理解起来有困难。教者对文本大胆进行重组，把问题和建议结合起来让学生有针对性的理解，这样会让学生的理解更直观深入。同时，教师渗透相关的环保理念，如：步行更环保，我们要对垃圾进行分类，种更多的树等等。

Step3. Post-reading 1.

Complete the proposal

a.

T: Today we talked about the environment, we should keep our city clean. In our school, some city guards are

talking about the environment too. They do a survey in Rudong, and draw many pictures, let’s enjoy.

b.

Do you want to be a city guard? It’s your turn. Take out your paper, you can discuss in groups, use your own

words to complete it, then show us. Dear friends: Our city is not clean now. ___________makes the air dirty. ___________makes ______________________ dirty.________________________________.

To keep our city clean, we can ________________________________.____________________________. ___________________________________. Let's do it right now. __________(name) 【设计意图】教师将文本中的环保镜头拉回到现实生活中，以儿童画配英文解说的形式为完成倡议书埋下伏笔，学生在真实的情境中，通过小组讨论，内化语言知识，并输出目标语言。

2.

Present the slogan T: If we do that, our city will be more beautiful in the future. Let’s say “Better city, better life!”

Step4. Homework 1. Appeal to your friends to keep our city clean. 2. Search for more about environment on the Internet and give a speech in the next lesson. 【设计意图】学生在课后向朋友们宣传环保理念，将课内知识延伸到课外，并通过上网的形式，搜索更多关于环境方面存在的问题和解决的措施，准备下节课演讲。
