1. New words and phrases: robot, post, brain, whatever, explore, outer space, put out fires

2. New structures: I’m complaining about you to the robot shop.

         I don’t know when I’ll post the letter for you.

IV. Teaching Procedures

Comic strip

Step 1 Lead-in

Free talk

T: What is Hobo?

S: It is an e-dog.

T: Yes. We can also call it a robot dog. What can it do for its master Eddie? (Showing pictures)

S: Hobo can read books/watch TV/plant trees.

T: Look at this picture. What can it do for Eddie?

S: It can post a letter for Eddie.    

【设计意图：通过谈论Hobo为Eddie所做的事情，引出新词汇robot和post a letter，并以此引出Comic strip的内容。】

Step 2 Presentation

1. Watch and answer

T: Now let’s enjoy a video and answer the following quesions.

(1) What is Eddie doing now? Why?

(2) Will Hobo post the letter for Eddie?

(3) What does he say? Can you act it out?

2. Act out the dialogue

【设计意图：通过听读、模仿、表演对话，一方面帮助学生理解，另一方面激发他们的学习兴趣。】

Welcome to the unit

Step 1 Lead-in

The usage of robots

T: Hobo, a robot dog, is so lovely and clever. What do other real robots do in our daily life? For example, what can a robot waitress do?

S: A robot waitress can serve people.

  A robot worker can carry things.

  A robot cleaner can clean the floor.

A robot guide can guide visitors.

  A robot pet can play with children.

  A robot player can play football.

【设计意图：了解机器人的用途是本节课的重点。考虑到学生对机器人比较陌生，所以本环节通过图片导入，然后引导学生根据提示回答。】

Step 2 Presentation

1. Part A

T: What can robots do for humans? Let’s read and match each phrase with the correct picture.

T: How do we understand the phrase explore outer space?

T: Read the sentence and guess the meaning of the new words.

【设计意图：对于初三学生，适当地根据词根、词缀拓展词汇学习对于培养他们良好的词汇积累习惯很有必要。】

2. Films about robots

T: Have you ever seen the film WALL-E? The robot Wall-E works on the Earth for nearly ten years. Do you think it is interesting? Let me tell you more about it.

T: It is an American science-fiction comedy film and came out in 2008. It was produced by Pixar Animation Studios and was released by Walt Disney Pictures. It is about a robot named WALL-E, who is designed to clean up a waste-covered Earth. He falls in love with another robot named EVE, who also has a task to do, and follows her into outer space on an adventure that changes the future of both his kind and humanity. 

T: What do you think of the robot?

T: I think he is clever and it seems that he can think.

    I don’t doubt that he has a brain like us, so they can do whatever they are asked to.

    So, here brain means 大脑 in Chinese. 

【设计意图：通过观看视频，生动形象地呈现生词，并激发学生对机器人的热爱。】

T: Have you ever seen the film I, robot?

T: The story tells us that in 2035, humans live with robots happily. Robots can do whatever they are asked to for humans. But one day, something happens ….

T: What about this film? Yes, 《机械战警》 in Chinese. Have you ever heard of it?

T: The story tells us that in 2028, a policeman came back to life as a robot. He plays an important role in protecting people’s safety.

【设计意图：中学生对科幻电影普遍比较感兴趣，因而本环节结合课本内容，给学生推荐他们喜欢的电影，同时介绍机器人的用途，在激发他们的想象力的同时，又能引起他们在下个环节中参加对话的兴趣。】

Step 3 Practice

T: If you had a robot, what would you like it to do for you? Why?

T: What are Daniel’s and Amy’s ideas about robots? Let’s listen to a dialogue between them and answer questions.

T: How could robots help us in the future? Have a talk with your partner and then act it out in front of the class.

【设计意图：在掌握了足够多的关于机器人的信息后，学生已经具备了“输出”的能力。通过对话，可以了解学生对本堂课知识的掌握情况，也能提高他们对知识的运用能力和表达能力。】
