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 used 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 used in offices and homes since the 1970s.These 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 myself, 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 used to make mobile phones as well as help with medical operations.I have even been put into space rockets and sent 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 several years ago.Last year our team went to Seattle, Washington in the USA.We won second 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 seen while watching human games.Then she prepares reliable moves to use if a new situation arises.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!

Volunteer!

S1: / think in this story, the speaker is a computer.T: Quite right.Now write down three sentences from the story to support your idea.Who can? S2: / began only as a calculating machine in 1642 in France.S3: Then in 1822 I was built as an Analytical Machine by Charles Babbage.S4: Earlier I was not very big, but then I became huge!

T: Very good, there are some more similar sentences in the text.You may find them out in your spare time.Task 2 T: Now, please look at the timeline on page 19.Then fill in the blanks with information from the Reading above.Students will be asked to tell the details to the class.Now, who would like to give your answer? S5: 7642: A calculating machine was used in France.S6: 1822: The Analytical Machine was made by Charles Babbage.S7: 7936: Alan Turing wrote a book to describe how computers could be made to work and built a ”universal machine" to solve any mathematical problem.S8: 1960s: Computers got new transistors.S9: 1960s: The first family of computers connected to each Other.S10: 1970s: Computers were brought into people's homes.Sll: 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: Your details are quite right.From the details we can see the timeline of computer history.We must remember it.Are you clear?

第四篇：高一英語人教版必修二Unit 5 課文內容

Unit 5 Music Have you ever wanted to be part of a band as a famous singer or musician? Have you ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous.But just how do people form a band?

Many musicians meet and form a band because they like to write and play their own music.They may start as a group of high-school students, for whom practising their music in someone’s house is the first step to fame.Sometimes they may play to passers-by in the street or subway so that they can earn some extra money for themselves or to pay for their instruments.Later they may give performances in pubs or clubs, for which they are paid in cash.Of course they hope to make records in a studio and sell millions of copies to become millionaires!

However, there was one band that started in a different way.It was called the Monkees and began as a TV show.The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles.The TV organizers had planned to find four musicians who could act as well as sing.They put an advertisement in a newspaper looking for rock musicians, but they could only find one who was good enough.They had to use actors for the other three members of the band.As some of these actors could not sing well enough, they had to rely on other musicians to help them.So during the broadcasts they just pretended to sing.Anyhow their performances were humorous enough to be copied by other groups.They were so popular that their fans formed clubs in order to get more familiar with them.Each week on TV, the Monkees would play and sing songs written by other musicians.However, after a year or so in which they became more serious about their work, the Monkees started to play and sing their own songs like a real band.Then they produced their own records and started touring and playing their own music.In the USA they became even more popular than the Beatles and sold even more records.The band broke up about 1970, but happily they reunited in the mid-1980s.They produced a new record in 1996, with which they celebrated their former time as a real band.FREDDY THE FROG(II)Not long after Freddy and the band became famous, they visited Britain on a brief tour.Fans showed their devotion by waiting for hours to get tickets for their concerts.Freddy was now quite confident when he went into a concert hall.He enjoyed singing and all the congratulations afterwards!His most exciting invitation was to perform on a TV programme called “Top of the Pops.” He had to go to London, wear an expensive suit and give a performance to a TV camera.It felt very strange.But as soon as the programme was over, the telephones which were in the same room started ringing.Everybody was asking when they could see Freddy and his band again.They were truly stars.Then things went wrong.Freddy and his band could not go out anywhere without being followed.Even when they wore sunglasses or beards people recognized them.Fans found them even when they went into the toilet.They tried to hide in the reading rooms of libraries, but it was useless.Someone was always there!Their personal life was regularly discussed by people who did not know them but talked as if they were close friends.At last feeling very upset and sensitive, Freddy and his band realized that they must leave the country before it became too painful for them.So they left Britain, to which they were never to return, and went back to the lake.
