Unit 3 WHO AM I?book2

 冰姿飒飒 2015-01-12
 
Over time I have been changed quite a lot. I began
as (介词,作为……a calculating machine (计算机器)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
(介词,作为…… an analytical machine(分析机) by Charles Babbage.
 
After I was programmed by an operator who used cards with holes(穿孔卡), 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 1949s 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.
 
Over time my memory has developed so much that, like an elephant, I never forget anything (that)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 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(万维网). 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 andhave been used to make mobile phones as well as(=and) help with medical operations.
