USING LANGUAGE

Listening and writing

The purpose of this exercise is to encourage students to listen and then use what they have heard to help them fill in a chart about computers．It is an important exercise because it links skills together and uses them to produce a useful piece of writing．

Make sure the students look at the chart before they listen to the tape．This is to sharpen their attention and listen for the answers．This will also help them get the gist of the text．When filling in the chart, the students will have to use their own experience as well as information from the listening text．

LISTENING TEXT LI MING: What are you doing Dave? DAVE: I'm reading about information technology．

LM: You mean things like computers? In my opinion they're so boring to read about．They're only good to use．

D: But they're just one kind of IT．

LM: Really? So what else is part of IT? D: We've had IT for a long time．Books, radios and TVs are also kinds of IT．

LM: Oh．I never thought of that before．Books are a wonderful way for us to get information．

D: Yeah, I believe that too．They are cheap and easy to take with you but sometimes the information is out of date．

LM: I agree．The world is changing so fast．But in my opinion listening to sports on the radio is better than anything else．Sometimes I also listen to English programmes on the radio．But they speak so fast and sometimes it's difficult to understand everything．

D: Yes．I also listen to English on the radio but it's easier to follow on TV because you can also see what is going on．Sometimes it is more interesting to watch sports on TV than just listen to them on the radio．

LM: I disagree because you get such a lot of information on the technical aspects of a game on the radio．You don't get that on TV．But I still think that the computer is the best kind of IT．You can watch a film on it, write to friends, get information, and find out what is going on in the world．

D: I know, but it is also the most expensive and it is too big to carry with you everywhere．Also the Internet has nobody to check whether that information you find there is correct．So you have to be careful．

LM: Well, I suppose all kinds of IT have both disadvantages and advantages．

Suggested answers: Type of IT
