Reading Comprehension Passage One In what now seems like the prehistoric times of computer history, the earth’s postwar(战后) era, there was quite a wide-spread concern that computers would take over the world from man one day. Already today, less than 40 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 drastic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they believe 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 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 may have gone wrong. Questioning and routine double-checks must continue to be as much a part of good business as they were 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. 1.What is the main purpose of this passage?
