picture 5. we can use them for writing computer programs.

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.
