Today's home work for English conversation school

Today, Many computer programs are at work.

It is not only in PCs, but also in machines which is are near-at-hand.

the other hand, a lot of computer programs also have Graphical User Interface (GUI).

A lot of GUI are coping copy the color and shapes from real User Interface(UI),

like buttons, meters, needles on that and etc...

But GUI is only graphic.

GUI doesnot include mechanisms which beare constructed for their function.

So, their action is given by designer (or programerprogrammer).

I think today's designers (or programers programmers) have more experiment experience of with real life with some observation.
