Passage Two:Questions 16 to 20 are based on the following passage.The human brain contains
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.
第16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.
