The human brain contains 10 thousand million cells and each of these may have a thousand c

onnections. 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 6me 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 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 increased to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on each through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further a head, 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.

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.

A Biological Clock

Every living thing has what scientists call a biological clock that controls behavior. The biological clock tells(51)when to form. flowers and when the flowers should open. It tells(52) when to leave the protective cocoons and fly away, and it tells animals and human beings when to eat, sleep and wake.

Events outside the plant and animal(53) the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur(54) the number of hours of daylight. In the short(55) of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer.

Inner signals control other biological clocks. German scientists found that some kind of internal clock seems to order birds to begin their long migration(56) twice each year. Birds(57) flying become restless when it is time for the trip,(58) they become calm again when the time of the flight has ended.

Scientists say they are beginning to learn which(59) of the brain contain biological clocks. An American researcher, Martin Moorhead, said a small group of cells near the front of the brain(60) to control the timing of some of our actions. These(61) tell a person when to(62), when to sleep and when to seek food. Scientists say there probably are other biological clock cells that control other body activities.

Dr. Moorhead is studying(63) our biological clocks affect the way we do our work. For example, most of us have great difficulty if we must often change to different work hours.

Dr. Moorhead said industrial officials should have a better understanding of biological clocks and how they affect workers. He said(65) understanding could cut sickness and accidents at work and would help increase a factory's production.
