Dialogue one
Let's start to study how to use computers ,Paubler.It's good to know that a
computer has two major parts,the hardware and the software.
What's the hardware?
The hardware of computer is basically all the concrete things you can touch
with your hands and see with your eyes.
That's seems obvious enough.then what about the software?
The software of computer is all the programmes inside the computer that
allow you to use the computer to do things.
I see,actually the hardware is the easy part,I do want to study how to use
the software.
Right you are,Paubler,and since what you want to learn is how to use
software ,we should also learn to refer to the computer menus.
Ever since I saw computer can do your project,I wanted to have a
computer.
Dialogue two
Do you know much about computers?
Not a great deal.
I've just been reading an article about them.they'll be used for all sorts
of things now.
For accounting system and things like that ,you mean ?
Yes ,but they are used for other things,too.Do you remember when we went to
buy a ticket for the flight to Paris .
Yes?
The man asked where we want to go,then he type out the information on the
form and waited for a reply.A few moment later ,he gave us two tickets.
Of course,his machine must have been connected to a computer.
That's right.
Dialogue three
Well,known,Jim ,I'm...I'm pretty much in favour of your computers,I think
computers teach kids to think ,because they require logical thoughts.
But I...I don't agree with that ,because computers weaken kids' ability to
think,because kids don't learn basic skills.
What do you mean?
They can't spell ,they can't add,they can't subtract,they even don't
remember any more.that's because they rely on gadgets.
That's not the gadgets.Creating programmes is stimulate thoughts. It
engages their imagination and sharpen their mind.
The computer is an important factor in our lives,each year ,we use
computers more and more to help us to connect data and to provide their
information ,at one time,people thought computers were only used for banks
,dapartment stores and governments,but today ,the rapidly increasing number of
computers are used for many other purposes.The clothes you wear were probably
manufactured with the help of a computer.The newspaper you read could have been
edited and typed by a computer.Even TV programs and commercials are often
prepared by computers,there is no reason to think that their uses will
decrease.Computer will become a greater part of our lives.
