Is the Computer Too Clever?
The computer is fast, and never makes a mistake, while people
are too slow, and full of mistakes sometimes. That's what people
often say when they talk about computers. For over a quarter of a
century(世纪), engineers have been making better and better
computers. Now a computer can do a lot of everyday job wonderfully.It is widely used in factories, hospitals and banks. A computer can
report, decide and control(控制)in almost every field. Many
computer scientists are now thinking of making the computer "think"
like a human. With the help of a person, a computer can draw
pictures, write music, talk with people, play chess, recognize(辨认)voices, translate(翻译)languages and so on. Perhaps computers
will one day really think and feel. Do you think that people will
be afraid when they find that the computer is too clever to listen
to and serve the people?判断下列句子是否符合短文内容,符合的用“T”表示,不符合的用“F”表示。1. People always make a lot of mistakes while computers don't.(
