Teaching goals

● To introduce the topic of computer

● To activate existing vocabulary and identify the meaning of new words related to the topic

● To guess meaning from pictures

● To talk about the use of computer

Teaching procedures

Step 1 Having a free discussion

A: What do you like doing?

B: I like reading online.

A: Do you like watching TV?

B: Yes, I do.

A: Which do you like better, watching TV or playing computer games?

B: I like playing computer games better.

A: Why?

B: Because it makes my excited.

Step 2 Presenting

Do you have a computer?

Do you often use your computer?

What do you use them for?

Can you tell me different uses of computers?

(Show pictures in Part A on page 41)

Picture 1 We can use them for drawing and designing.

Picture 2 We can use them for searching for information.

Picture 3 We can use them for word processing.

Picture 4 We can use them for playing games.

Picture 5. We can use them for writing computer programs.

Picture 6 We can use them for sending and receiving e-mails.

Step 3 Having a discussion

What do you usually use computers for?

There’s a dialogue between Daniel and Simon. Read it and answer:

What does Simon usually use his computer to do?

How often does he use it to search for information?

Work in pairs to talk about the different uses of computers. Use the conversation in Part B on page 41 as a model.

Step 4 Presenting

There’s a story happening between our old friends Eddie and Hobo. They have no ideas about computers. Let’s look at the pictures.

?What does Eddie regard the mouse as? ?A remote control.

?Why does Eddie think the mouse is a remote control? ?Because when Eddie moves the mouse, something appears on the screen. They think the computer is a television.

Step 5 Finding and writing expressions

You are to go over page 40 and 41 again to find out and write down all the useful expressions. Make sentences of your own with them after class.

Expressions from Comic strips & welcome to the unit

Have no idea, look like a …, the remote control, turn …on, change the channel, love using the computer, hold a writing competition, write about…, at one’s school, present…to…, learn more about…, enter the writing competition, show the different uses of …, play games, search for…, send and receive e-mails, write computer programs, find out…, use…for…, use…as a model, replace…with…, fast and easy

Step 6 Doing a listening task

Now, listen to the dialogue, and then answer the following questions:

1. Do they know anything about the computer?

2. What does Hobo think the computer looks like?

3. Why does Eddie think the mouse is the remote control?

Usually, when a ‘blank screen’ screensaver is on, the screen remains dark as if the computer is off. When any of the keys or the mouse is clicked / moved, the screen would ‘turn on’ at once. That is why Eddie thinks he has turned it on.

The joke here is that both Eddie and Hobo have never seen a computer and so Eddie thinks the computer is a TV and the mouse is a remote control.

Step 7 Reading it aloud

Read the dialogue aloud, and then act it out.

Step 8 Doing homework

a. Read the comic strips and try to recite it.
