"A digital computer can usually be regarded as consisting of three parts: Store. Executive unit. Control. ...The executive unit is the part which carries out the various individual operations involved in a calculation. ...It is the duty of the control to see that... instructions are obeyed correctly and in the right order. ...A typical instruction might say—"Add the number stored in position 6809 to that in 4302 and put the result back into the latter storage position." Needless to say it would not occur in the machine expressed in English. It would more likely be coded in a form such as 6809430217. Here 17 says which of various possible operations is to be performed on the two numbers. ...It will be noticed that the instruction takes up 10 digits and so forms one packet of information..."

“原文：Sometimes it is the people who no one imagines anything of , that do the things that no one can imagine.”

“Can machines think?"... The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man , a woman , and an interrogator who may be of either sex. The interrogator stays in a room apart from the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B... We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?”

“Machines take me by surprise with great frequency.”

“Instruction tables will have to be made up by mathematicians with computing experience and perhaps a certain puzzle-solving ability. There need be no real danger of it ever becoming a drudge, for any processes that are quite mechanical may be turned over to the machine itself.”

“Some of the symbols written down will form the sequence of figures which is the decimal of the real number... being computed. The others are just rough notes to "assist the memory ". ...nly ...these rough notes ...will be liable to erasure.”

“The idea behind digital computers may be explained by saying that these machines are intended to carry out any operations which could be done by a human computer.”
