【C1】
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 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？
Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
The fridge is considered a necessary. It has been so since the 1960s when packaged food first appeared with the label:" store in the refrigerator."
Ira my fridgeless fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the Butcher(肉商), the baker, and the ice -cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus(乘余)bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.
The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well - tried techniques already existed - natural cooling, drying, smoking, salting, sugaring, bottling...
What refrigeration did promote was marketing - marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price.
Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially -cooled space inside an artificially -heated house -while outside, nature provides the desired temperature free of charge.
The fridge's effect upon the environment has been evident, while its contribution to human happiness has been insignificant. If you don't believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers(汉堡包), but at least you'll get rid of that terrible hum.
The statement "In my fridgeless fifties Childhood, I was fed well and healthily."(Para. 2, Line 1 )suggests that ______.
A．Because their parents want them to share the family burden.B．Because their parents a
