问题     (77)In what now seems like the prehistoric times of computer history, the early post-war era (战后时期)  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(过分信任) 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 ).
    (78)Obviously, there would be no point in investing(投入) 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 ail their answers
C、substitute them for basic thinking
D、use them for business purpose only
答案A
解析 事实细节题。山第二段可知，作者在建议人们应依靠自己的大脑，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。所以选A，意思是要持理性怀疑态度，也就是不要盲目地完全依赖它。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，所以B曲解了作者的用意。C(用电脑代替人脑)是作者在文中最反对的；D(仅将电脑用于商业)太片面了。
