any longer.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 resultI totally changed my shape .As I have grown older I have also grown smaller .Over time my memoryhas developed so much that ,like an elephant,I never forgrt anything I have been told !And my memory became so large that even I couldnt believe it!But I was always so lonely standing there by myself,until in the 1960s they gave me a family connected by a network .Iwas 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 .A nyhow, 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 ! ANDYTHE ANDROID Im part of an an android football team .About once a year we are allowed to get together to play a game of football.Im as big as a human .In fact ,I look like one too.On the footballteam Im a striker so I have to be able to run very fast .My computer chips help me to mova and think like a human .For example ,I have learned to signal to my teammates in computer languages to give me the ball when I am open and have a good shot for a goal. My firat football competition was in Nagoya ,Japan several years ago .Last year our team went to Seattle ,Washington in the USA.We won tsecong place .Personally ,I think the team that won firsy place cheated .They had developed a new type of program just before the competition.So we need to encourage our programer to improve our intelligence too.We are determined to create an even better system.In a way our programmet is like our coach.She programs us with moves to use if a new sitation arises.In this way I can make up new moves using my “artifical 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 Im all about! THE SPORTING ROBOT My name is Hua Fei and I am a sporting robot of the 23rd century.I am an expert at high flying exercises.I jump from spaceship and as I fall I turn,dive,circle and dance until I softly land as close as I can to the finishing line.Robot competitions in the 23rd century are truly a popular sport.Fans from all over China watch their handheld TVs when a competition comes on.Last time I look part in the 78th Olympic on a flying island above Brussels in the sky.I won the siver medal for my performance . This year I had the honour to be chosen again .I wanted to mmet robots from other countyies and explore ides about our sport.Hower ,my programmer fell ill the week before we were going to leave .It was very painful for her and I felt very frightened.I no longer felt so confident that I would win. The day of the competition was rather could for my legs and my special oil began to fteeze.I paused before I jumped from the starting place on a little spaceship but then I began my performance.At the correct moment I tried to open my parachute but there was a problem.It only opened a little .In stead of flying softly to earth I began to fall faster and faster so that I could not turn ,dive,circle or dance.My heart stopped beating as I landed heavily on a mountain covered with snow. This is why I am writing to you from my hospital bed with two broken legs and a fragile head.I did not win anything at the Olympic after all.I need the factory to build me two new legs and an even bigger head.Then I will be able to compete once more .Lets hope foe greater success in the next Olympics! Unit 4 (1) How Daisy learned to help wildlife Daisy had always longed to help endangered species of wildlife.One day she woke up and found a flying carpet by her bed.“Where do you want to go?”it asked.Daiasy responded immediately.“Id like to see some endangered wildlife,”she said.“please take me to a distant land where I can find the animal that gave fur to make this sweater.”At once the carpet flew away and took her to Tibet. There Daisy saw an antelope looking sad.It said,“We are being killed for the wool beneath our stomachs.Our fur is being used to make sweaters for people like you .As a reasult,we are now an endangered species.”At that Daisy cried,“Im sorry I didnt know that.I wonder what is being done to help you.Flying carpet,please show me a place where theres some wildlife protection.” The flying carpet travelled so fast that next minute they w
