问题     In what now seems like the prehistoric times of computer history, the early 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 facing 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 (失灵).
    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.
The passage recommends those dealing with computers to ______.
选项 A、be reasonably doubtful about them
B、check all their answers
C、substitute them for basic thinking
D、use them for business purpose only
答案A
解析 细节题。根据第二段内容可知，作者建议人们应该依靠自己的大脑，对待计算机要持“questioning(敢于怀疑)”的态度，并采取“double check(仔细检查)”的手段。故选A，即要持理性的质疑态度，不要盲目地完全依赖计算机。作者并没有说完全不信任计算机，要逐一核对答案，这样计算机恐怕真的要扔掉了，B选项曲解了作者的意思。C选项“用电脑代替人脑”，这是作者在文中最反对的。D选项“仅将电脑用于商业”过于片面。故选A。
