阅读理解 As a teenager in 1972, Bill Gates boasted that he would be a millionaire by the time he was 20.While he did not quite achieve that goal, only 15 years later he was a billionaire. And by 1992,as head of the Microsoft company, he became the richest man in America with assets (资产) of approximately US$ 6.3 billion. Born in Seattle, Washington on 28, October 1956, Gates was named William Henry after his father and grandfather. From the beginning, he was an extremely energetic and intelligent (聪明的) child. He had read the entire world book encyclopedia (百科全书)by the age of nine. His favorite subjects at school were science and maths and his favorite past time was 'thinking'. Gates first started to play with computers at the age of 13,when one was installed (安装) at his school. At that time, computers were large, awkward (笨重) machines. Operators were required to learn complex (复杂的) computer languages before the machines could be used. Even then, a great deal of time and effort was needed to perform the simplest functions. Before long, Gates was an expert at working the school's computer. After his graduation from secondary school, Gates was accepted by the three top universities in   USA -- Princeton, Harvard and Yale. He chose Harvard and began classes there the next autumn, majoring maths. But he was still obsessed (占据, 心思) with computers and spent as much time in the computer laboratories as he did in the lecture halls. By 1975,Gates and a partner, Paul Allen, had developed a software called BASIC. This was not the first program ever created, but its inventors were the first to decide that people who wanted to use it should pay for it. BASIC was a success because until it came along there had been no efficient way of getting computers to carry out instructions. Although he had not yet completed his degree, Gates left university and went to work full time for the new company he had formed called Microsoft. His next project (项目) was the software program that made him famous and very rich. It was called DOS, short for Operating System, and it was purchased (购买) by IBM in 1980.Today it is the operating system used in more than 14 million personal computers around the world. As chief executive officer (首席执行官) of Microsoft, Gates is known as a bright man, but one who is not easily satisfied. He is quick to criticize ( 批评) his staff and hates to be questioned about decisions he has made. He was regarded as a loner an unfashionable boring computer nut until his marriage to Microsoft manager Melonda French on New year's Day 1994.Yet to most people now, Gates is a person who is, in spite of his great wealth, humble (谦恭) and ordinary. He spends his money carefully, he eats in fast-food restaurants and flies economy (经济) class. And when praised for Microsoft's great success, he has been heard to say, 'All we do is put software in a box and if people see it in the stores and like it, they buy it.' 1.
