阅读理解。
Bill Gates was born in 1955. He grew up in Seattle, Washington. When he was young, he was good at
science and maths. And he wanted to be a scientist.
Bill started to play with computers when he was 13. At that time, computers were very large machines.
Once he was interested in a very old computer. He and some of his friends spent lots of time doing unusual
(不寻常的) things with it. In the end, they worked out a software ( 软件) program with the old machine. Bill
sold it for 4200 dollars when he was only 17.
In 1973, Bill went to Harvard University (哈佛大学). He developed the Basic language for the first
microcomputer (微型电子计算机). In his third year, he left Harvard. Bill began his company in 1975 with his
friend Paul Allen. They thought that the computer would be a very important tool in every office and in every
home, so they began developing software for personal computers. They developed the software to make it
easier for people to use computers.
In 1999, Bill wrote a book. In the book, he told people how computer technology could solve business
problems in new ways. It was one of the best-sellers on The New York Times' list. Bill Gates has many
hobbies. He enjoyed reading very much. He also enjoys playing golf and bridge.
1. When did Bill begin to play with computer?
A. In 1965.
B. In 1966.
C. In 1968.
D. In 1972.
2. How old was Bill when he went to Harvard University?
A. 17 year sold
B. 18 year sold
C. 19 year sold
D. 20 year sold
3. Bill left Harvard University when he was a _____.
A. first-year student
B. second-year student
C. third-year student
D. fourth-year student
4. Bill wrote a book about _____.
A. how to do unusual things
B. how to play computer s.
C. how to work out a software program
D. how to solve business problems with the help of computer in new ways
5. We can learn from the text that _____.
A. Bill worked for Microsoft before he went to Harvard University
B. Bill sold his first software program for 420 dollars
C. Bill began his company in 1976 with his friend
D. reading is one of Bill's hobbies

【单选题】下列说法符合原文意思的是哪一项?() A.半导体集成电路计算机,发展到现在已经没有发展前途了。 B.生物计算机与数学电子计算机的基本原理是一致的。 C.生物计算机出了故障可以“自我修复”,因此不会损坏。 D.目前,生物计算机已成了科研热点,许多国家都在进行这方面的研究工作。

A.
(三)阅读下面短文,回答下列五题。
B.
1946年诞生的世界上第一台计算机,体积达90多立方米,重30多吨。后来有了半导体,造出了超大规模集成电路,使电子计算机体积大大减小了。但这种集成电路小型化已接近极限,要在这基础上提高其存储和运算速度也越来越难。
C.
由于计算机最基本构件是开关元件,于是专家们设想,假若有机物分子也具备“开”“关”功能,岂不可以造出“有机物计算机”吗后来,科学家发现,半醌类有机化合物分子及蛋白质分子中的氢都具备“开”“关”这两种电态功能。因此,从理论上说,只要用半醌类有机化合物分子或蛋白质分子作元件,就能制造出“半醌型”或“蛋白质型”的计算机。人们把它们称为“生物计算机”或“分子计算机”。
D.
生物计算机具有“半永久性”。它有许多优点:一是密集度可达现在集成电路的10万倍;二是运算速度可达半导体开关件的1000倍以上;三是这种由生物分子构成的“生物芯片”也同一般生物一样,具有“自我修复”功能,出了故障可“自我修复”,所以这种生物计算机可靠性高,经久耐用;四是生物元件是用化学能工作,所需能量甚少,不存在元件发热问题。
E.
生物计算机的研制始于20世纪60~70年代。美国1983年11月召开了专门学术会议,对生物计算机的研制从理论到实践进行了深入探讨。 日本此项研究由“未来电子仪器科研协会”和通产省指导进行。英国也拨款3000万英镑用于生物计算机的研究开发。
F.
目前,生物计算机的研制处于初始阶段,专家们预计,下世纪初叶,可望有突破性进展,并使数字电子计算机产生新的功能。无疑,生物计算机一旦问世,将是计算机科学领域的一次新的革命。
