25、sh into Chinese)Directions: Read the following passage carefully and then translate the underlinedsentences into Chinese. (20%)(1) Drr. Claude Shannon of Bell Telephone Laboratories, and his colleague, E. F. Moore, once built a machine to play the game known as Hex, using an analog computer working

26、on electrical voltages. It beat them about 70 per cent of the time. “It frequently surprised its designers by selecting odd-looking moves which, on analysis, proved sound, Shannon comments.(2) Each of these mechanical game-players is said to “l(fā)earn” because it is so programmed that it follows the Bo

27、olean algebra pattern, discovering by sad experience that one thing or another doesnt work and profiting by mistake. One of Shannons more fantastic triumphs is the magnetized mouse” which, when placed in a complicated maze consisting of partitions, is supposed to find the one and the only path to th

28、e “cheese.” On the first try the mouse will stumble aimlessly around running into one wall after another. Eventually，by repeated try and error, it will locate the cheese. If the mouse is given a second try, it will go straight to the cheese without hitting a single blind alley. It will, do it from a

29、ny part of the maze. (3) Moreover, if its trainer changes the maze on it by relocating the partitions, the mouse blunders only where the terrain has become unfamiliar. It can recognize at once positions that have not been changed. Eventually the mouse learns enough to forget all former arrangements

30、and remember only the latest, successful ones.(4) The mouse itself does not think, but it is difficult to argue against the thinking done by the electromagnet and computer that drive the mouse. The device does havethe ability to distinguish between right and wrong, and to revise its standards on the

31、 basis of its own experience.Probably the clearest difference between man and machine is a quantitative one. The brain has roughly a million times as many parts as the best computer. On the other hand, the difference may lie in a spiritual factor, embraced by religion.
