2. 让学生读对话,找到答案并进行讨论。教师可引导学生说:
Ss: The bird is sad because it lost its home and the fish is sad because the water is dirty. Our home is becoming worse and worse, so we should care for our earth.
T: What should we do? Today, we will learn some activities and you can see they are right or wrong.
II. 课程展示活动和过程的设计建议(Presentation)
i. 新课展示Part A Let’s learn
1. 学习短语pick flowers
教师出示所准备的一束花并与学生进行对话:
T: Look. What are these?
Ss: They are flowers.
T: What color are they?
Ss: They are...
T: In which seasons can we see many flowers?
Ss: Spring and summer.
T: Well. We can see many beautiful flowers in the garden. I want to pick some flowers and take them home. Can I do that?
Ss: No.
T: No. We can’t pick flowers.
教师板书并领读短语pick flowers,注意纠正学生的错误读音。
2. 学习短语cut down trees
教师出示一次性筷子并与学生进行对话:
T: Look at these chopsticks. What can we do with them?
Ss: We can eat with them.
T: Well. People often use them in our daily life, but where are they from?
Ss: They are from trees.
T: Yes. Trees are cut down to make chopsticks. Usually, we use them only once. Every year, people cut down many trees. Do you think it is right?
Ss: No.
T: So we can’t cut down too many trees.
教师板书并领读短语cut down trees,学生边做动作边说短语。
3. 学习短语drive a car
教师假装摘花,问学生:What am I doing? Can I pick flowers? 然后问学生:Can we cut down many trees? 教师再做开车的样子,通过问答,用不同的句式反复介绍短语:
T: What am I doing, can you guess?
I’m driving. I’m driving a car. I can drive a car.
可连续和几个学生进行问答活动:
T: Can you drive a car, S1?
Can you show us how to drive a car?
教师板书并领读短语drive a car,要求学生边说短语边做动作。

5. 通过图片引导学生认读词汇the earth.
教学小贴士
the earth, the sun, the moon这三个表示天体的名词前都要用定冠词the。教师要特别提醒的是,earth的发音是以元音因素开头的,其前面所用的定冠词读[ei?]
6. 教师播放Let’s learn部分的录音,让学生模仿其语音语调跟读词汇。
ii. 巩固活动
教师再次播放Let’s learn部分的录音,可注意在每个短语之后停顿几秒,让学生听音拼写词汇。
III. 操练活动的设计与实施建议(Practice Activities)
i. 看图抢读
1. 教师先将学生分成若干组,然后出示所准备的短语卡片,让学生看图快速抢读出相应的短语。
2. 教师也可以请每组派出一个代表出示卡片,其他成员抢读短语。
ii. 句型转换:对不文明行为说“不”
教师说出一个本单元的短语,学生听后判断认为是不文明行为,说: Please don’t...根据学生掌握情况,可添加一些类似于play sports, eat healthy food等短语,学生若认为是文明行为,就说:Let’s...

II. 课程展示活动和过程的设计建议(Presentation)
i. 新课展示 Part A Let’s talk
教师出示此部分的教学挂图,引导学生观察图片。
T: Oh. Let’s take out the books and open them. It’s time to go to school. Let’s see how Su Nan is going to school today. How is he going there? Let’s listen to the dialogue.
(1)教师播放录音,并就对话提出第一个问题。
Question 1: How will Su Nan go to school?
听完对话后,教师请学生回答问题。教师引导学生用完整的句子说出问题的答案:He is going to school by bike.
(2)教师让学生根据所查找的资料讨论世界无车日的相关背景知识,然后教师再予以补充。
教学小贴士
世界无车日
2000年2月,欧盟委员会及欧盟的9个成员国确定9月22日为“无车日”。这是一个旨在改善城市空气质量、减少城市交通压力和改变城市交通观念的环保活动。截至2006年,全世界已有37个国家的近1500个城镇参与其中。2007年9月22日是中国的第一个“无车日”,活动主题为 “绿色交通与健康”。需要强调的是:“世界无车日”活动并不是拒绝汽车,而是要唤起民众对环境问题的重视。
(3)教师再次播放对话的前两句录音,并就本段对话进一步提出问题,让学生找出更多问题的答案。
Question 2: Does Su Nan have some more soup? Why?
教师引导学生回答:No, he doesn’t. Because he has no time. He has to clean his bike. 然后让学生找出文中的原句:I have no time. I have to clean my bike.
教师板书句型:I have to clean my bike.并讲解have to的用法,即:have to do ...表示“不得不做某事”。并引导学生练习用have to造句:I have to get up early /do my homework /cook breakfast /wash my clothes...
(4)教师再次播放剩余部分,然后引导学生会话,进一步帮助学生理解对话:
T: Why will Su Nan not go to school in his dad’s car?
Ss: We shouldn’t drive the car today.
T: Why?
Ss: Because today is World Car Free Day.(教师帮助学生说出答案)
教师板书并讲解句型:Why not go in your dad’s car? Why not do …?
教师要注意创设具体的情境帮助学生理解Why not…?的用法。
It’s hot today. You are wearing your shirt and pants. Why not wear your T-shirt and shorts?
It’s Sunday today. We don’t have any classes. Why not go skating?
教学小贴士
Why...? 和Why not.
1. ---Why?
---Because...
这是典型的就原因问答的句型结构。当我们不明白某种现象原因时,可直接用Why?或Why构成的特殊疑问句进行询问;回答时可直接陈述理由或用because引导出原因。
---Why are you late for class?
---Because I went to bed very late last night and got up late this morning.
2. Why not do…?表示“何不……为什么不……?”是一种用来向别人提出建议的句型,也可用来反问。如:
We are free tomorrow. Why not go to the park together?
教师板书并讲解句型:
We shouldn’t drive the car today.
我们今天不应该开车。
We should do something for our earth.
我们该为我们的地球做点事。
We should /shouldn’t do ...我们应该/不应该……常用来陈述个人对某种现象的看法和观点,而something在这里指“一些事情”。
教师拿出play sports, do eye exercises, have a rest, pick flowers, cut down trees, make the air dirty, waste water这些词汇的图片,引导学生做出判断,运用句型We should /shouldn’t do ...说话造句子。
ii. 听读练习
教师播放Let’s talk部分的录音,让学生听录音跟读对话。教师注意纠正学生的错误发音。以下方式供教师教学参考:
1. 学生集体听录音跟读对话,要求学生指读。
2. 学生分组听录音交叉跟读对话,要求学生指读。
3. 学生分角色朗读对话,教师及时给予评价。
II. 操练活动的设计与实施建议(Practice Activities)
i. 看关键词表演对话
1. 教师先在黑板上写一些关键词,引领学生根据这些关键词的提示进行对话练习。
2. 教师和一位学生看关键词进行对话示范。
3. 学生看关键词分组进行对话练习。

参考答案:(1) many, mountains (2) too many (3) too much, dirty
2. 教师让学生勾画出各自在阅读课文时遇到的不熟悉的词语,先请同学们根据语境猜猜这些词语的意思,之后教师解疑答惑,讲解短语care for, do bad things to.
(1)care for关心、爱护;如:
Alice has a white rabbit and she cares for it.
(2)do bad things to对……做坏事,损坏……;如:
We are friends. We shouldn’t do bad things to each other.
教师鼓励学生试着用care for、do bad things说话,或教师给出汉语让学生说出英语:
1. 爸爸妈妈都很爱护我。
2. 我们要爱护这些小树木。

There is too much bread on the table. (修饰名词bread)
I’m very busy today, because I have too many things to do.(修饰名词things)
