about them in class.S1：An abacus is an old calculating machine used in China until now.S2：A huge computer is built to solve some mathematical pro blems.But，in my opinion，it is too big.S3：A calculator is a new calculating machine which can solve a large number mathematical problems.And I think it is very convenient to carry and use，so we ofte n use it.S4：A PC is a personal computer，which can solve all kinds of problems and is widely used in offices，schools，shops，at homes，etc.now.S5：A notebook computer is a kind of useful computer which can be taken conveniently like a notebook.But I think it is

perhaps one day you will design your own computers and become the masters of computers.OK!Next question!S10：I think computers have changed our lives greatly.We use computers widely in our study，in our work.You are using the computer to teach us English，aren’t you?S11：In my opinion，in the modern society，using the computers means grasping a tool of controlling the world.We may communicate with each

have.I was in France as a calculating machine in 1642.In 1822，I was built as an Analytical Machine by Charles Babbage.I was called “a universal machine”in 1936，as I could solve any mathematical problem.In the 1960s，I was given a family connected by a network，so that I could share information with others and we could talk to each other.In the 1970s，I was brought into people’s homes.T：You are so quick-minded that in such a short time you could find out all the answers to the questions.Your mind really works like a computer!Step 4 ComprehendingTask 3.Fill in the timeline to remember the

development of computers.Now who would like to retell the text with the help of these figures?S1：Let me try.In 1642，a calculating machine was used in France.Then in 1922，the Analytical Machine was made by Charles Babbage.It could follow instructions from cards with holes.In 1936，Alan Turing，the real father of computers，wro te a book to describe how computers could be made to work and built a “universal machine”to solve any mathematical ter，people discoveredthe computer had “artificial intelligence”.In the 1960s，the computer got his new transistors.Its size was totally changes at that time.And in the early 1960s，the first family of computers were connected to each other.In 1970s，computers have brought into people’s homes.Now computers have been used by billions of people to deal with information and communicate with each other around the world by the Internet.T：Congratulations!You’ve done very well.Now try to do the same to your partners，OK!Step 2 Words and ExpressionsTask 1T：Please turn to Page 19 and finish Discovering Useful Words and Expressions.At first，look at Ex.1.From the reading passage，find the words and expressions with the following meanings.Now，ten students

Unit 3 Computers 教案2(WHO AM I? <PART 2>)IntroductionYou are advised to lead in by talking about IT. Then help students write a report about IT. ObjectivesTo discuss about ITTo write a report about ITTo read about androids or robotsProceduresI. Warming up by talking about ITWhat is Information technology?Information technology (IT) or information and communication technology (ICT) is the technology required for information processing. In particular the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information from anywhere, anytime.II. Listening and writingTurn to page 21.Look at the pictures and listen to a conversation about different kinds of information technology or IT, discuss and write down in groups the advantages and disadvantages of each kind.III. Speaking and writingSuppose you and your partner are going to help choose computers for your school. Now talk about the special things each of the computer can do and write a report to your headmaster.IV. Reading, underlining and speakingIt is said that computers could be put into androids or robots. Read the text Andy—The Android, underlining all the expressions and think of the fun you could have!Expressions from Andy—The Androidp art of a football team, once a year, get together, play a football game, be as…as…, in fat, look like…, on the football team, run fast, think like a human, shout to…, in computer language, have a good shot for a goal, get second place, win the first place, have a new kind of program, improve one’s intelligence, create a better system, play against a human team, in a way, program…with…, make up…, after all, with the help of…V. Close down by writing a letterSuppose you are an android. What would say to a spoiled child who would not do his homework? Write a letter to the boy.AndroidAn android is an artificially created being that resembles a human being.The word derives from Greek Android- ‘man, human’ and the suffix -eidesused to mean ‘of the species, kind, alike’ (from eidos ‘species’).The word droid, a robot in the Star Wars universe, is derived from this meaning. Some people maintain that, etymologically, the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided; however, this word is not commonly used.Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical), the word android has been used in literature and other media to denote several different kinds of man-made, autonomous creations:a robot that closely resembles a humana cyborg that closely resembles a humanan artificially created, yet primarily organic, being that closely resembles a humanAlthough essentially human morphology is not the ideal form for working robots, the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence).The term android was first used by the French author Mathias Villiers de lisle-Adam (1838-1889) in his work Tomorrow’s Eve, featuring a man-made human-like robot named Hadaly. As said by the officer in the story, “In th is age of Realien advancement, who knows what goes on in the mind of those responsible for these mechanical dolls.”。
