When an invention is made, the inventor
has three possible courses of action open to him: he can give the invention to
the world by publishing it, keep the idea secret, or patent it.
A granted patent is the result of a bargain made between an inventor and
the state, by which the inventor gets a limited period of monopoly (垄断) and
publishes full details of his invention to the public after that period
terminates (终止).
Only in most exceptional circumstances is the
life-span of a patent extended to alter this normal process of events.
The longest extension ever granted was to Georges Valensi: his 1939 patent
for color TV receiver circuitry was extended until 1971 because for most of the
patent’s normal life there was no color TV to receive and thus no hope of reward
for the invention.
Because a patent remains permanentl
A. steal and use
B. give reward to
C. make public
D. take and change

[单项选择] Passage Two
Between the invention of agriculture
and the commercial revolution that marked the end of the Middle Ages, wealth and
technology developed slowly indeed. Medieval historians tell of the centuries it
took for key inventions like the watermill or the heavy plow to diffuse across
the landscape. During this period, increases in technology led to increases in
the population, with little if any appearing as an improvement in the median
standard of living.
Even the first century of the industrial
revolution produced more "improvements" than "revolutions" in standards of
living. With the railroad and the spinning and weaving of textiles as important
