听力原文： We cannot feel speed. But our senses let us know that we are moving. We see things moving past us and feel that we are being shaken. We can feel acceleration, an increase in speed. But we notice it for only a short time. For instance, we feel it during the take-off run of an airplane. We feel the plane's acceleration, because our bodies do not gain speed as fast as the plane does. It seems that something is pushing us back against the seat. Actually, our bodies are trying to stay in the same place, while the plane is carrying us forward.
Soon the plane reaches a steady speed. Then, because there is no longer any change in the speed, the feeling of forward motion stops.
How do you explain that we are moving？
A．By watching things move past.
B．By feeling the speed.
C．By feeling ourselves being shaken.
D．Both A and C.
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 over power.
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.
