Teaching procedures: Step1

Lead-in Introduce the term “information technology”.

T: We are now in a new century. As you may have heard, it will be a century of information technology. How do you understand this frequently used term? Encourage students to voice their own opinions. S: I think IT is closely connected with computers. Without computers, there would be no IT.

S: I guess IT refers to the computer-based information systems, which include software application and hardware. S: …

Show the definition of IT on the screen to help students better understand this term.

What is IT? IT is the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. In short, IT deals with the

use of electronic computers and computer software to convert, store, protect, process, transmit and retrieve information, securely. Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term is more recognizable than ever before. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include: 

教师播放《变人》片段选取两姐妹在海边玩耍到Andrew为向小姐道歉，用树根雕刻了一匹小马给她，并且得到了她的原谅。

1.T：Hello, everyone. Let’s watch a video. Please watch it carefully& tell me what the Robot in the video is doing? 【设计意图】让学生观看该段有关机器人的flash片段自然地导入该课的主题，以便帮助学生大致了解到机器人在人类日常生活中可以做的事情,同时

能活跃课堂的气氛，为下步阅读策略的教学做了有效的铺垫。

2.T：

Get the students to watch some pictures of Androids dancing .And ask them to think about how they can dance.

T:

Imagine what other things androids can do ? 【设计意图】在这节以语言输出为目标的综合技能训练课中，学生既要完成读的任务，又要完成说与写等综合性语言运用任务。因此利用多媒体图片，以帮助学生想象机器人在人类的日常生活中所起的作用。同时在具体语境中处理一些有用的词组和句型：With the help of 、look like 、deal with、…They work as a …、They can…and…为后面的小组讨论做好铺垫，激发他们说的欲望。

Step3：Reading 将学生分成若干小组，并给各组布置以下任务：Read one of the following topics and then describe to others in English.

Who(identity) appearance function his wish

Details 【设计意图】利用表格形式集中呈现四个问题，让学生带着问题去精读文章，这样有助于他们快速捕捉文章更多信息，对文章大意有所了解。并且该教学步骤采用Jinsaw Reading 这一合作互动的阅读教学策略，旨在通过阅读不同内容在小组成员间建立信息沟，然后在阅读的基础上进行信息的有效地口头传递，以实现信息的交流的资源的共享。学生在完成此类任务时表现得积极、主动、交流也较真实。

Step3：Group Discussion Get the students to watch some other pictures of Android.

And ask them to think about the following questions : a. Where are they ? b. What is the function of the Androids?

c. Can you describe their appearances?

d．If you have a chance to design your Android, what would you like your Android to be? 教师让学生分组讨论以上问题，并要求学生在讨论中运用表达观点和做决定的功能用语。

Giving opinions a.I think that …

b.In my opinion…

c.I believe that…

Reasoning

a.I think this one is better ,because…

b.I don’t like this one ,because…

c.The advantage /disadvantage is …

Making a decision a.

Let’s make our decision

b.

I’ve decided…

【设计意图】设计该教学环节的目的之一是通过小组活动引导学生共同讨论，促使学生运用本单元中刚学过的语言及有关交际功能。学生根据以上所学语言自主运用语言的过程。这样的活动既关注了语言形式，有关注了语言内容，实现了让学生在真实语境中运用英语及交际策略的目标，体现了“用语言做事，在做事中学会语言”的教学原则。同时把学生分成小组讨论能使学生写作积极性提到最高点，使写作活动更具有交际性，可帮助启发学生的写作灵感。并为后面的写作打好伏笔。

Step4:

Listening

Deal with activities 1-3 on page 22.

T: Excellent opinions! Now discuss in pairs what IT consists of. Make a list and compare your ideas with another pair.

Give a few minutes for them to discuss and make a list. T: Now you will hear a text about IT which will tell you more about it. First listen and get the main idea of the text. Write down the main idea in one sentence. Play the tape for the first time. Then check the sentences they write.

T: What does IT include? What is the most popular form of IT? Now listen to the first part again and fill in the chart, Part A. Play Part A, check the answers. T: Which form of IT describes the skills of a sport best? Which form of IT has the most functions? Now listen to the second part again and fill in the chart, Part B. Play Part B, check the answers.

Step 5: Speaking Get students to talk about the advantages and disadvantages of each form of IT in

groups, using the reasoning expressions. Then decide when each kind of IT is most

useful.

T: Look at the expressions in activity 4. Which are used to make decisions? Ss: The advantage/disadvantage is …

I think/don’t think that …

I believe that …

I’ve decided that …

T: Then which ask about reasons? Ss: What’s your reason?

What makes you thinks so? T: Good! Which are used to state reasons? Ss: I think … because (of) …

I agree/don’t agree … because …

First … Second …

As/Since …, I think …

T: From the listening material, we have learned about the different forms of IT such as computer, TV, book and radio. Now work in groups and discuss: What are the advantages and disadvantages of each form of IT? Use the expressions we just talked about. Then fill in the chart with your discussion results.

It’s better that students work in groups of four and each focus on one form of IT.

Sample discussion: A: I think computer is the most powerful IT form because it can store plenty of information in various forms. The advantage of computer IT is that the information can be updated at anytime and you can get almost information when connect with Internet.

B: I think TV is the most popular form of IT and can be accepted by people at any age. It is easy to operate and there are more and more channels and programs to choose from. As most people still prefer to get information or have fun from TV, I think TV will continue to be a dominant IT form in the 21st century.

C: I think radio has many disadvantages. D: What makes you think so? C: First, you can only hear but can’t watch. Second, the information that you can get from it is very limited. However, it also has its advantages. You can listen to radio programs when you are driving, walking or doing housework. What’s more, it’s small and easy to take.

D: I prefer to read books. I think book is the most reliable IT form. The information in books are usually better selected and organized. Compared with TV and computer, books do less harm to eyes. You can read them again and again. While the disadvantage of book IT that it is expensive.

After discussion, ask some group representatives to report their results.

Step6:

Homework T: Chips play a very important role in computer technology. They are the “core” of computers. How much do you know about chips? After class, please find some information about it.
