我第一次足球比赛是几年前在日本的名古屋。去年，我们 队去了美国华盛顿州的西雅图比赛，获得了第二名。我个人认 为得冠军的那个队作弊了。他们恰恰在比赛前研制了一种新程 序。因此我们也需要鼓励我们的程序编制员来提高我们的智能。 我们决心创造一个更好的系统。从某种程度上看，我们的程序 员就像是我们的教练。她把观看人类比赛时所看到的一切可能 的动作编入我们的程序，然后她把我们在新情况下能用得上的 可靠动作准备好。这样，我就可以用我的“人工智能”编制出 新的动作。我真的特别喜欢和人类球队比赛，因为我经过程序 编制，行动起来和他们一样。不管怎样，在我过目不忘的电子 脑的帮助下，运用智能就是我的一切！

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.

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!
