问题    In what now seems like the prehistoric times of computer history, the earth’ s post-war era, there was a quite widespread 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.
   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 following 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 根据第一段第三句“People tend to be over-trusting of computers and are reluctant to challenge their authority．”可知，人们过分信任计算机，也不愿意挑战它的权威。根据第二段第一句“…but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong．”可知，人们也应该依靠自己的头脑，在感觉有问题的时候进行检查。再根据文章最后一句话“…it should not be seen as a substitute for fundamental thinking and reasoning skills．”可知，计算机不能成为人类基本思维和推理能力的替代品。由此可以看出，作者表达了他的担忧，即面对计算机时，人们不愿意动脑子，思维上变得懒惰。故选D。
