Step II 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 record 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. 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 again, check the answers.

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. Step III Speaking In listening part, we got to know the computer has the most functions. Now, let’s have brain storm. What can we do on a computer in our daily life? Practice sentence structure:

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

useful.

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.

Step V Interview and report

Smart phones are widely used in our daily life and also among our young teenagers. How to use the smart phone properly becomes an important issue. Now, divide students into several groups and ask them to have a discussion on it. Choose a

reporter in each group and ask group members some questions, and then report the opinions. For example: Do you have a mobile phone? How often do you use your mobile phone? What do you do with your mobile phone? What do you do with your mobile phone? Sample report: I have interviewed 4 students, and 2 of them have their own smart phones. They usually use the smart phone once a week to relax themselves, like listening to music, watching TV series and so on. All of them regard it as a useful invention and a good helper in daily life.

Step VI Homework T: VR glasses are often becoming famous. Have you experienced that before?
