18 二、课文解析

19 Write a book about…to solve…problem
Over time (在一段时间里)I have been changed quite a lot. I began as a calculating machine in France in 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 分析器by Charles Babbage. After I was programmed by an operator 程序员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(请分析本句结构). 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 could grow any larger. However, this reality also worried my designers (worry sb让某人担心). As time went by (as time going by), I was made smaller. First as a PC and then as a laptop, I have been used in offices and homes since the 1970s Write a book about…to solve…problem

20 These changes only became possible as (as是什么意思)my memory improved
These changes only became possible as (as是什么意思)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 shapes. 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(为何没有was). I was able to share my knowledge with others through the World Wide Web. (share…with) 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 (也)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 (provide…with..). I am now truly filled with happiness that I am a devoted friend (忠诚的朋友)and helper of the human race! (be filled with充满) 1. 像...一样; 2. 当...时3. 随着 As the sun rose the fog dispersed. 4. 因为5. 虽然Tired as he was, he sat up late. standing 分词，作主语I 的补语，补充说明主语的状态 I am very happy, missing you. 我想你的时候，很快乐 That引导的从句是happiness的同位语从句， that不担任成分，没有意思，但不能省略
