Passage 2
Questions 6 to 10 are based on the following passage:
The human brain contains 10 thousand million 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 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.
(78)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 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 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, man-created world in
space, home to thousands or millions of people, will be within our power.
6. 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.(C)
7. What does the writer think about machines with human-like ability?
A) He believes they will be useful to human beings.
B) He believes that they will control us in the future.
C) He is not quite sure in what way they may influence us.
D) He doesn’t consider the construction of such machines possible.
8. The word “carbon” (Line 4, Para. 2) stands for ________.
A) intelligent robots B) a chemical element C) an organic substance D) human
beings(D)
9. A robot can be used to expand our frontiers when ________.
A) its intelligence and cost are beyond question
B) it is able to bear the rough environment
C) it is made as complex as the human brain
D) its architecture 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-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 posses
intelligence
D) robots will have control of the vast, man-made world in space
