课文讲解

WHO AM I?

【1】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.

【2】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.

【3】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. 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!

Even thousands of years ago, groups of people gathered to watch skilled athletes(运动员). Over 2,000 years ago in Greece, some days in the year were festival days. These were holidays when people stopped their work and enjoyed themselves. During festivals, people liked to watch athletes take part in races and other games. The most important festival was held every four years at the town of Olympia. It was held in honor of the Greek god Zeus. For five days, athletes from all corners of Greece took part in the Olympic Games. At the Olympic Games, people could watch athletes run, jump and so on. They could also watch exciting races, which included a relay race between two teams in which a lighted torch(火炬) was passed from runner to runner. The Olympic Games were thought to be so important that cities throughout Greece which were at war with one another had to stop fighting. During the time, people were allowed to travel to the Games safely. Thousands of people came to the Olympic Games from cities in Greece and from its colonies(殖民地) in Africa, Asia, and Italy. They met as friends to cheer their favorite athletes and to enjoy themselves. 1. What did people do at the Olympic Games? A. They fought for their freedom. B. They just talked to friends. C.
