L= Laura D= Dave Part A
D: Hi, Laura. It’s good to see you because I’m so bored . My homework is about Information Technology but I know everything there is to know about it.L: Come off it, Dave. I think I might know more than you.
D: OK. Let me test you! Here’s the first question. What’s information technology?
L: Gosh, that’s easy! It’s computer, of course.
D: Ah! That’s just where you’re wrong.It includes books, radio and TV as well.
L: Really! Well, I never.
D: Question number 2. Which is the most popular form of IT in the world?
L: Well, that must be computers this time.
D: No, it’s books. Think of all those people in developing countries without
computers. Their only form of IT is books!
L: Oh dear! I’m not doing very well.Part BD: Here’s the third question. Which form of IT is the best for describing the skills of a sport?
L: It must be the radio.
D: Actually, it’s not. The best descriptions are on the TV because you can not onlyhear the technical language, but also see how it happens.
L: Goodness! Wrong again!
D: Here’s the last question. Which form of IT has the most functions?
L: This time I must be right. It’s the computer, of course.D: Yes. You can watch a film, replay a match, communicate with friends through the Internet, get information
and find out what’s going on in the world.
L: Oh dear! Three questions wrong out of four. Perhaps I don’t know as much about IT as I thought I did!Discussion

B: I've decided that we should have a homework android. It could do all our work after class and leave us more time to do football．
A: OK. But what do you think it should look like?B: In my opinion, it should have four arms to carry the books, a large head to remember all the lessons and a printer to write out the answers． What do you think?
A: Well, that sounds sensible. Perhaps it could also put all the exercises into specially marked boxes for eachsubject so we could find them quickly.
What about putting that in its stomach area?

My robot’s name is Yanyan. It is a 321 model android. It works for me and looks after my library. Its job is to store all the books that I borrow from the library or from school. Of course Yanyan’s brain is as large as mountain so work like that is no trouble at all. Yanyan really eats and remembers books just like people eat food.I need Yanyan to remember all these books, so it can help me do my homework. I want to go to a key university but finding the
information I need is hard work. So Yanyan can help me. This leaves me more free time to play sports and talk to my friends. It is the most important thing for me and my family.

The Present Perfect Passive VoiceReading For FunThis is a poem written as if it were by a robot. The poor-robot is treated as if it has no feelings, but in fact it wishes to be free and play like a real girl. This is not a poem by a famous poet but it does nicely express how robots might feel when regarded as servants and not given any consideration as people.Answer key for Exercise 1 Page 56
