Step2 Presentation
T: Three steps to protect the Earth: I know, I do and I try. Let’s come to the first step.
（1） I know
①T: Here are some riddles:
We can call coal and oil________.——energy
We drink it every day. We can see it in rivers and lakes.——water
They are green. We can see them in the forest.——trees
We can use it to make bottles and bags.——plastic
T: We know they are useful. Can you say the usage of them in Story time
S: We drink water and use water to clean things.
We use energy to drive cars.
We use wood to make tables ,chairs and many other things.
We use plastic to make bags and bottles.
T: Well done! In our daily life, we also use water to water trees and flowers. We use water to cook meals. We use water to wash clothes and dishes. We use coal to warm ourselves. We use oil to make clothes, medicine, food and many other things. We use wood to make paper, toys, chopsticks and many other things. We use plastic to make slippers, raincoat and many other things. We use plastic to decorate house. We also use it to wrap things.
②Read and find:
Rule: use sth. To do sth.
③Think and say: use… to…
water → sit
We use water to plant trees. → We use trees to make wood. → We use wood to make chairs. → We use chairs to sit.
wood → eat
We use wood to make chopsticks. → We use chopsticks to eat.
T: Now it’s your turn to think and say.
water → read plastic → go shopping
活动要求： 1、两人合作，一人说一句。
2、说完一题后，尝试另外一题，看看谁说得最多！
3、说完后，尝试把句子写下来。
water → read wood → eat plastic → go shopping
[设计意图]：通过口头操练，学生对use sth. to do sth. 这一句型已经很熟练，但是落实到笔头很容易漏掉to，设计写一写这一作业，可以帮助学生在练习中减少错误。
T: You did a good job. In our daily life, we use a lot of water, energy, wood and plastic. But overuse of them is harmful. We should do something.
（2） I do
①T: What should we do to protect the earth
Ss: We should save energy, save water, save trees and don’t use too much plastic.
T: Yes. Because the earth is our home. We should protect our home.
So what should we do What should we not do Discuss in pairs.
Ss: 学生回答（板书）
②Read and find
Rules: should/ should not do sth.
T: We shouldn’t use a lot of them. We should reuse them.
③T: First, collect some paper, plastic bags and plastic bottles.
Teach: collect
T: Then, how can we reuse these things
I can reuse paper to make a box. I can reuse a plastic bottle to make a toy.
Teach: reuse sth. to do sth.
T: Look at our friend Sam. He wears special clothes. He collects some bottles. He reuses them to make clothes. And I collect some bottles too. I can reuse bottles to make pen containers. How about you What do you collect How can you reuse these things
④Show time
要求：1、四人一小组，利用以下句型问答，在组内展示各自废物利用作品。
2、派一名代表向大家展示你们组的作品。
S1: What do you collect
S234: I/ We collect some…
S1: How can you reuse these things
S234: I/We can reuse…to make…
Report:We can reuse… to make…
[设计意图]：Fun time这个环节本来就应该是以娱乐为主的，而且这一课时的内容本来就比较少，所以可以让学生把手工制作带进课堂，通过做手工、展示手工和介绍手工的方式，在具体的操作中操练新句型，这样比较有趣。
（3）I try
T: You did an excellent job in reusing the waste. Every one of us can only do a little to protect the earth. But we can try our best to make more people take action to protect it. Let’s make a poster.
要求：1、4人一小组,分工合作，结合课内外知识，设计完成海报。
2、主题明确，对其他人有启示作用。
[设计意图]：保护地球这一主题，学生很愿意去实践，但是光靠他们的力量是远远不够的，所以制作主题相关的海报并宣传，可以让更多的人加入到保护地球的行动中来，学生也可在这一活动中体验成功的喜悦。
Step 3 Homework
1. Finish your poster and try to make more people take action.
小组成员完成海报并张贴，让更多的人加入保护地球的行动中来
2. Try to reuse the things around you in your daily life.
