Unit 3 WHO AM I?book2

 

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 and（have been） used to make mobile phones as well as(=and) help with medical operations.
