9、ion cells and each of these may have a thousand connections. (77)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、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 renderit intelligent by loading in the right software (軟件)or by altering thearchitecture but that too will happen.(78)1 think it certain that in decad

11、es, not centuries, machines of silicon (硅) 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 toreproduce themselves. Silicon will have ended carbon' s long control. And we willno longer

12、 be able to claim ourselves to be the finest intelligence in the known universe.As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environment

13、s, 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 withi

14、n our power.6.

What does the writer think about machines

17、tecture is different from that of the present ones(A)10. 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 self-reproductionB) with the rapid development of technology, people have come to realize the possibility

19、 but instead are rather well into it. " Present predictions are that by 1990, about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related. In 1980, only twenty-one percent of all United States high schools owned one or more computers for s

And now educational experts, administrators, and even the general public are demanding that all students become acomputer literate (慢點(diǎn)的).""

22、ot; about computers, but knowing what. The current opinion seems to be that this should include a general knowledge of what computers are, plus a little of their history and something of how they operate.Therefore, it is vital that educators everywhere take a careful look not only at what is being d

23、one, but also at what should be done in the field of computer education. Today most adults are capable of utilising a motor vehicle without the slightest knowledge of how the internal-combustion engine works. Weeffectively use all types of electrical equipment without being able to tell their histor

24、ies or to explain how they work. (80)Business people for years have made good use of typewriters and adding machines, yet few have ever known how to repair them. Why, then, attempt to teach computers by teaching how or why they work?Rather, we first must concentrate on teaching the effective use of

25、the computer as the tool is.“Knowing how to use a computer is what' s going to be important, we don' t talk about ' automobile literacy. ' We just get in our cars and drive them.”11.
