问题     Everyone must have had at least one personal experience with a computer error by this time. Bank balances are suddenly reported to have jumped from $379 into the millions, appeals for charitable contributions are mailed over and over to people with crazy sounding names at your address, department stores send the wrong bills, utility companies write that they’re turning everything off, that sort of thing. If you manage to get in touch with someone and complain, you then get instantaneously typed, guilty letters from the same computer, saying, "Our computer was in error, and an adjustment is being made in your account."
    These are supposed to be the sheerest, blindest accidents. Mistakes are not believed to be the normal behavior of a good machine. If things go wrong, it must be a personal, human error, the result of fingering a button getting stuck, someone hitting the wrong key. The computer, at its normal best, is infallible (没有错误的).
    I wonder whether this can be true. After all, the whole point of computers is that they represent an extension of the human brain, vastly improved upon but nonetheless human, superhuman maybe. A good computer can think clearly and quickly enough to beat you at chess, and some of them have even been programmed to write obscure verse. They can do anything we can do, and more besides.
    It is not yet known whether a computer has its own consciousness, and it would be hard to find out about this. When you walk into one of those great halls now built for the huge machines, and standing listening, it is easy to imagine that the faint, distant noises are the sound of thinking, and the turning of the spools (线轴) gives them the look of wild creatures rolling their eyes in the effort to concentrate, choking with information. But real thinking and dreaming are other matters. On the other hand, the evidences of something like an unconscious, equivalent to ours, are all around, in every mail. As extensions of the human brain, they have been constructed the same property of error, spontaneous, uncontrolled, and rich in possibilities.
The passage is mainly about______.
选项 A、why there are so many computer errors
B、whether computers make mistakes
C、how to avoid computer errors in our daily life
D、the difference between the human brains and computers
答案B
解析 本文首先列举若干电脑出错的事例，说明电脑出错无所不在：接下来讨论是否有可能杜绝电脑出错；最后得出结论：电脑出错是不可避免的。由此可知，本文主要讨论了电脑是否会出错，故答案为B)。第二段虽然提到人们认为电脑的错误一定是人为造成的，但这并非作者本人的观点，故排除A)。首段虽然列举了电脑出错的种种表现，但全文并未提出解决问题的办法，故排除C)。作者在第三段阐述了电脑是人脑的延伸，但并未将人脑和电脑的异同做具体比较，故排除D)。
