问题     In what now seems like the prehistoric times of computer history, the earth’s postwar era, there was quite a wide-spread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction (失误).
    Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.
    Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.
What is the main purpose of this passage?
选项 A、To look back to the early days of computers.
B、To explain what technical problems may occur with computers.
C、To discourage unnecessary investment in computers.
D、To warn against a mentally lazy attitude towards computers.
答案D
解析 本题是一道考查作者写作目的类问题，主要考查学生的概括能力。需要在阅读完文章之后准确地理解全文的用意。问题问本文的主要目的是什么。根据文章大意，第二次世界大战之后，当计算机刚刚问世时，人们普遍担心，有朝一日计算机将取代人类在世界上的地位。而不到40年后的今天，当计算机真的把我们从越来越多的日常公务和日常生活琐事中解脱出来的时候，我们却面临一个新问题，虽说不上令人吃惊，但却是人们未曾预想到的问题：人们过分信赖计算机，简直不愿意挑战其权威性。似乎人们不知道有的时候也可能会按错键，或者说计算机也可能出现失误。因此，我们可以推断出本题的正确答案应是D“告诫人们防止对计算机产生懒惰的依赖心理”。A“回顾计算机的早期状况”；B“说明计算机可能出现的技术问题”；C“试图劝阻人们没有必要就不要购买计算机”；这三个选项都是错误的。
