教学过程

In the past

now

In the future

Step1 : Warm up 1. Free talk Eg:

T: What’s the weather like today?

How about yesterday? Was there a canteen in our school five years ago? How about now? Talk about the changes about you. [设计意图] 从谈论天气的变化到学校以及学生的变化，这些与学生生活实际相联系的话题能调动起学生的表达欲望，缓解刚上课的紧张情绪。

2. Enjoy the song

T: You are all different now. How about Wu Yifan? Let’s enjoy a song

课件播放歌曲动画Changes in me，学生欣赏歌曲。

T：What are the changes about Wu Yifan? S1: He is taller than before. S2: His shoes are bigger than before. ……

[设计意图]这首歌曲用优美的曲调与动画很好地展现出吴一凡的变化，学生在欣赏歌曲的同时能自然记住主要的信息点，也为进一步完成Let’s check部分的练习做好铺垫。

Step 2. Presentation Let’s check 1. T: Wu Yifan’s grandpa is talking about his old school. What was his school like? What did he often do? Let’s listen carefully and number the pictures.

课件播放Let’s check部分的录音，学生边看图边仔细听。

2. Check the answers together, ask some questions about the pictures. Eg : How did he go to school?

What did he do in the winter?

Did he read books in the library? 3. Play the tape again, cross the words you didn’t hear. Read the key words together. Let’s wrap it up 1. T: Changes are all around us. Talk about the changes below. 课件出示Let’s wrap it up 部分的图片，学生描述图片。

Eg: It was an egg. Now it is a hen.

2. Talk about the picture with your partner. [设计意图]本部分通过图片描述练习，复习了一般过去时和一般现在时，提醒学生在描述时特别注意be动词和动词的变化。

Story time 1. Pre-reading: T: Do you like reading magazines? Ss: Yes, they are interesting. T: Mmm, I like to read magazines, too. Look, Zoom and Zip are reading a magazine, what’s the magazine about? How many parts are there in the story? Now, let’s look at the story. Have the students talk about the story with their partners, then report for the class.

(设计意图：引导学生通过观察故事中的图片，找出故事的主题，从三个方面体现过去、现在和将来的变化，与同伴交流。学生带着问题准备阅读，在思考中阅读，在阅读中思考，激发学生阅读兴趣。) 2．While-reading (1) Read the story and try to understand it. Part1 Cooking 课件出示《疯狂原始人》图片

T: Who are they? Ss: They are cavemen T: Did they cook their food? Ss: No, they didn’t cook their food. T: Yes. They didn’t cook their food. They ate raw meat. （课件分别出示农村土灶和现代厨房以及家用机器人）

T：In 1980s, people cooked like this, and now, there are many things to help us cook. How about the future? Ss: There will be house robots. T: What will they do? Ss: They will cook, clean and wash the dishes. T: What can you learn from the first part? S1: I knew the changes of cooking from this part( in the past, now and in the future) T: Nice work! [设计意图]

课本所提供的有关烹饪变化的素材比较少，借助多媒体的优势，可让学生了解更多与烹饪有关的内容，吸引学生注意，拓展学生的知识面。

Part2 The earth （课件出示地球图片）

T：What was the earth like in the past? Look, was it beautiful? Ss: Yes, it was so beautiful! There were many green trees and there were many clean rivers. T: How about now? （课件出示高楼林立的城市）

S1: There are more and more buildings. The sky is grey.

T: Oh, yes, and you can’t see any birds, because there are not many trees in the city. What a pity! What can we do for the earth? S2: We should help the earth now, we can plant trees, save water, don’t waste ….... Part3 Whales

（课件出示科学家展示鲸鱼化石的图片）

T: This is a fossil of whale. Scientist found that before humans lived on the earth, whales already lived in the sea. Have you ever seen whales? Ss: No. T: Now there are not many whales. Why? （课件出示鲸鱼被捕杀的图片）

S1: Because people fish them and kill them. T: Every year, hundreds of whales are fished and killed. And also because the sea is polluted, many whales kill themselves on the beach. What can we do to help whales? Ss: We should change/protect the environment/……

T: We should heal the world. [设计意图]

结合学生的亲身体会和课件展示，使学生体会到环境恶化、人为破坏给城市生活和鲸鱼生存带来的不良后果，引发学生的情感共鸣和深度思考。

(2) T: Read the passage again and you can find more information in the story, then try to fill in the table in groups.

Check the answers together. Retell the main clue of the story.

[设计意图]

在第二次阅读时，学生带着问题，根据需要，寻找细节信息，放慢阅读速度，小组合作，用找到的关键信息完成表格填写，巩固语言的操练和运用。

(3) T: You did a good job! Now, let’s watch the video of the story. （播放Story time的动画课件）

Ss: Listen and try to imitate the right pronunciation, tune and information. [设计意图] 观看动画课件使学生由故事的阅读到影像观看，图像和声音的同时刺激，使学生对故事和关键信息的理解更加深刻。通过再次听音模仿和跟读训练，

使学生学习准确的语音和语调，为角色表演做好铺垫。

(4) T: Read the story again. Circle the words you don’t know. And try to guess their meaning in the context. Ss: Here are the words: cavemen, whales, bright future, heal the world. T: Guess their meaning. Ss: I think cavemen means...

T: Now choose your favorite part and retell it with your partner. [设计意图] 学生在第三次阅读文本时，圈出自己不懂的单词，并联系上下文，学会在语境中猜测词义，进而更好地理解语篇。选择自己感兴趣的部分进行复述，学生的表达欲望会更强烈。

3. After-reading Talk about the theme of the story. T: Think about the question: What should we do to heal the world? Ss: Protect the earth. Plant more trees. Save water and don’t waste.

[设计意图] 阅读后，教师可以将故事的主题升华为保护地球，拯救世界，就是拯救人类自己让学生结合我们的生活环境遭到破坏，讲述各自的行动，培养学生动脑思考，有效地激发了不同语言层次学生的学习兴趣。
