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 couldn39。 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.

Her father said that she must marry, so Atlanta made a bargain with him. She said to him, These are my rules. When a man says he wants to marry me, I will run against him. If he cannot run as fast as me, he will be killed. No one will be pardoned. In fact, the room was not made to be a gift. It was designed for the palace of Frederick I. However, the next King of Prussia, Frederick William I, to whom the amber room belonged, decided not to keep it. In 1716 he gave it to Peter the Great. In return, the Czar sent him a troop of his best soldiers. So the Amber Room became part of the Czar39。s best artists about ten years to make.Unit1 Cultural relicsIN SEARCH OF THE AMBER ROOM Frederick William I, the King of Prussia, could never have imagined that his greatest gift to the Russian people would have such an amazing history. This gift was the Amber Room, which was given this name because several tons of amber were used to make it. The amber which was selected had a beautiful yellowbrown colour like honey. The design of the room was in the fancy style popular in those days. It was also a treasure decorated with gold and jewels, which took the country39。Many kings and princes wanted to ma
