　　The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability,but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon，in only 10 or 20 years perhaps，we will be able to assemble a machine as complex as the human brain,and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

　　I think- it certain that in decades not centuries*machines of silicon (桂)will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the knowledge.

　　As the intelligence of robots increases to match that of humans and as their cost dec ines through economies of scale we may use them to expand our frontiers first on earth through their alnlity to withstand environments, harmful to ourselves. Thus deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast,man-created world in space，home to thousands or millions of people， will be within our power.

　　It can be inferred from the passage that_.

　　A. after the installation of a great number of cells and connections robots will be capable of reproduction

　　B. with the rapid development of technology people have come to realize the possibility of making a machine with human-like ability

　　C. once we make a machine as complex as the human brain?it will possess intelligence

　　D. robot will have control of the vast,man-made world in space

　　On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the over 60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.

　　At six o'clock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry.

　　Over a cup of tea she wondered whether someone might have a key that fitted her front door-"a master key"perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that she went out at her usual time,dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.

　　It was just after four o'clock when the front door bell rang.Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the knob on the door-lock. Mrs. Clarke raised the kettle and poured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.
