1. Greeting.

2. Revision.

S: Protect the Earth.

T: So, today, let's go on learning this unit.

(先让学生说说story time是从哪四个方面来保护地球的。)

S: Save water, save trees, save energy and don't use too much plastic.

(师根据学生的回答进行板书。)

T：They are more useful to our daily life. What can we do with them?

(PPT呈现课件)

S1: We use water to...

S2: We use wood to...

S2: We use coal to...

T: They are really important to us.

（设计意图：复习旧知，巩固We use ...to...句型，为进一步学习做铺垫。）

Step 2: Checkout time

1.T:课件呈现水枯竭，树木被伐光等地球被破坏的图片，师讲解。

T: Save the world, save our lives. So, do you want to be the “environmental small guard” to protect the Earth?

(课件呈现“环保小卫士”的图片)

  S：Yes.

  T: If you want to be the "environmental small guard ". You should pass two tests, understand?

1.Test 1 (课件出示Test1的过关条件)

T：（出示书76页的图片）Look at the pictures, can we do like that?

S: No.

T: What should they not do? Open your books and try to complete the sentences.

T: Have you finished? Let's check the answers, picture 1, what should he not do?

S1：He should not smoke in the restaurant.

(继续每一幅图，逐图与学生反馈答案)

T: read these sentences together.

T: What other behavior should we not do? Discuss in pairs.

(小组讨论，反馈，师板书并适当拓展)

T：Oh, You have passed Test 1, congratulations.

2.Test 2(课件出示Test2的过关条件)

T: Just now, we talked about the wrong behavior, right?

S: Yes.

T: So, if you're the “environmental small guard”, what should you do to protect the Earth?

（引导学生从保护资源，保护生态，减少污染这几个方面来讨论，每一大组选择一个方向，四人为一小组汇报）

T：Excellent! you can protect the Earth well. I think you can be the “environmental small guard” now.

3.写作指导：

（1）例句：We should save energy .

仿写：We should                         .

We should                         .

We should                         .

We should                         .

（2）例句：We should save water.  We should save energy .

改写（合并成一句）：We should                    and                   .

自编一句：We should                    and                    .

（3）Write a passage. (书77页 Think and write)

T: (课件呈现图片，让学生以“环保小卫士” 的身份给人类写封信。) Tell us: what should we do and what shouldn't we do.

T: If you need any help, just put up your hands, and I will help you with the spelling.

(学生完成之后，请个别学生到讲台前展示短文)

（设计意图：通过争当“环保小卫士”这一主线，为学生布置任务，激活学生的思维，激发学生的学习兴趣，贴近学生的生活实际。）

Step 3 Presentation and consolidation

T: I think being an “environmental small guard” is a cool thing, do you think so?

S: Yes.

T: (课件出示图片) Look at this boy, what is cool to him? Let's listen.

       (课件出示句子并播放声音)

T：Yes. Why does he think so? Let's read together.

S: (read the sound time in different ways)

T: Look at the words, the "oo" is pronounced...?

S: /u:/

T: Good! Can you find more words like them？

S:（学生列举，教师板书)

T：Yes, and here are some words with the sound /u:/, can you read them? (PPT 显示单词，学生读)

T：And can you choose two of them to complete this sentence?

S：The house with a red roof, has a big swimming pool.

（设计意图：通过读句子，体会单词发音，让学生自己找相同发音的单词，教师出示新的单词让学生拼读，内化语音规律，培养学生根据读音规则来拼读单词的能力并拓展了词汇量。）

Step 4 Ticking time

T: Boys and girls, I think you did a good job just now. But did you do a good job for the whole unit? Let's check it out. Look! (PPT 显示4个目标) We have four targets in this unit. They are...
