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 in 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!

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. Daisy responded immediately. "I'd 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' re being killed for the wool beneath our stomachs. Our fur is being used to make sweaters for people like you. As a result, we are now an endangered species. " At that Daisy cried, "I'm sorry I didn' t know that. I wonder what is being done to help you. Flying carpet, please show me a place where there' s some wildlife protection. "

The flying carpet travelled so fast that next minute they were in Zimbabwe. Daisy turned around and found that she was being watched by an elephant. "Have you come to take my photo?"it asked.In relief Daisy burst into laughter. " Don' t laugh," said the elephant," We used to be an endangered species. Farmers hunted us without mercy. They said we destroyed their farms, and money from tourists only went to the large tour companies. " So the government decided to help. They allowed tourists to hunt only a certain number of animals if they paid the farmers. Now the farmers are happy and our numbers are increasing. So good things are being done here to save local wildlife".

Daisy smiled. " That' s good news. It shows the importance of wildlife protection, but I' d like to help as the WWF suggests. " The carpet rose again and almost at once they were in a thick rainforest. A monkey watched them as it rubbed it self. " What are you doing?" asked Daisy. "I'm protecting myself from mosquitoes," it replied. "When I find a millipede insect, I rub it over my body. It contains a powerful drug which affects mosquitoes. You should pay more attention to the rainforest where I live and appreciate how the animals live together. No rainforest, no animals, no drugs. "

Daisy was amazed. "Flying carpet, please take me home so I can tell WWF and we can begin producing this new drug. Monkey, please come and help. " The monkey agreed. The carpet flew home. As they landed, things began to disappear. Two minutes later everything had gone - the monkey, too. So Daisy was not able to make her new drug. But what an experience! She had learned so much! And there was always WWF...
