Answer 1

答案：1．C;2．B;3．C;4．A;5．C;
解析：

(1)	从第一段中的“Not very long ago, the computer was a strange machine．Not many people understood it．Not many people said yes to it”和“The first computer system was introduced for use in business in the mid-1950s”两句话得知。
(2)	从第一段中的“Since then, the number of computer systems used in business, government offices, and institutions has grown rapidly”可以看出。
(3)	最后一段可知。
(4)	从第二段设问句“Have you ever stopped to think how you are affected by a computer?”推断出。接着列举一些现象说明人们对计算机对人们的生活的影响没有察觉到：The clothes you wear were probably made with the help of a computer．The newspaper you read could have been edited and typed by a computer．Even radio programmes are often prepared by computers．
(5)	此句的含义是：虽然第一台计算机是在上个世纪50年代中叶开始使用的，然而仅过了五十年的今天它在生活的方方面面影响着数以亿计的人们。因此它表示计算机发展的速度很快。至于说“我们离开了计算机就无法生活”有些言过其实。
