单选题Directions: In this part there are four
passages, each with four suggested answers. Choose the one that you think is the
best answer. Mark your Answer Sheet by drawing with a pencil a short bar across
the corresponding letter in the brackets. 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 humanlike ability, but now 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 he 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 (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 he 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 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 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, mancreated world in
space, home to thousands or millions of people, will be within our power.
单选题
In what way can we make a machine intelligent?
A. By making it work in such environments as deserts, oceans or space.
B. By working hard for 10 or 20 years.
C. By either properly programming it or changing its structure.
D. By reproducing it.
【正确答案】
C
【答案解析】[解析] 依据文章第一段第6行中“loading in the right software”与“programming”相吻合。“altering the architecture”与“changing its structure”相对应。
