Unit 3 WHO AM I?
Over time I have been changed quite a lot.I began as a calculating machine in France in 1642.Although I was young I could simplify difficult sums.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.After I was programmed by an operator who ud cards with holes, I could “think” logically and produce an answer quicker than any person.At that time it was considered a technological revolution and the start of my “artificial intelligence”.In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a “universal machine” to solve any difficult mathematical problem.From then on, I grew rapidly both in size and in brainpower.By the 1940s I had grown as large as a room, and I wondered if I would grow any larger.However, this reality also worried my designers.As time went by, I was made smaller.First as a PC(personal computer)and then as a laptop, I have been ud in offices a离婚都需要什么手续和证件
nd homes since the 1970s.The changes only became possible as my memory improved.First it was stored in tubes, then on transistors and later on very small chips.As a result I totally changed my shape.As I have grown older I have also grown smaller.Over time my memory has developed so much that, like an elephant, I never forget anything I have been told!And my memory became so large that even I couldn’t believe it!But I was always so lonely standing there by mylf, until in the early 1960s they gave me a family connected by a network.I was able to share my knowledge with others through the World Wide Web.Since the 1970s many new applications have been found for me.I have become very important in communication, finance and trade.I have also been put into robots and ud to make mobile phones as well as help with medical operations.I have even been put into space rockets and nt to explore the Moon and Mars.Anyhow, my goal is to provide humans with a life of high quality.I am now truly filled with happiness that I am a devoted friend and helper of the human race!
ANDY-THE ANDROIDI’m part of an android football team.About once a year we are allowed to get together to play a game of football.I’m as big as a human.In fact, I look like
one too.On the football team I’m a striker so I have to be able to run very fast.My computer chips help me to move and think like a human.For example, I have learned to signal to my teammates in computer language to give me the ball when I am open and have a good shot for a goal.My first football competition was in Nagoya, Japan veral years ago.Last year our team went to Seattle, Washington in the USA.We won cond place.Personally, I think the team that won first place cheated.They had developed a new type of program just before the competition.So we need to encourage our programmer to improve our intelligence too.We are determined to create an even better system.In a way our programmer is like our coach.She programs us with all the possible moves she has en while watching human games.Then she prepares reliable moves to u if a new situation aris.In this way I can make up new moves using my “artificial intelligence”.I would really like to play against a human team, for I have been programmed to act just like them.After all, with the help of my electronic brain which never forgets anything, using my intelligence is what I’m all about!保密手机

g or a technological revolution.2.My real father was Alan Turing, who in 1936 wrote a book to describe how computers could be made to work, and built a ”universal machine“ to solve any mathematical problem.P18 T: Let's analyze the structure of this ntence.” problem“ is an attributive clau.In the clau, ”and“ connects two verbs: wrote and built.Step V Comprehending Task1 T: Class, plea go over the story and discuss with your partner who you think is the speaker in this story.Who would like to tell me?
