Do you know much about computers?
Not a great deal. Why?
I've been reading an article about computers. They are strange and are being used for almost everything.
Yes. But have you learned how to use one?
No. But I'm about to take a course on computers next term.
That's good. You have to know about computers. Computer knowledge is a must whatever you do. You should learn quickly or you will be left behind.
That's true. But first I want to learn the basics. In the library, there are computers. But it's a pity that I could not make use of them.
Well, I can teach you the ABCs, if you like.
