Science and Technology
There is a difference between science and technology._________(46). Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for applying the findings of science.________(47)
Progress in science excludes the human factor. Scientists, who seek to understand the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people’s likes or dislikes or to popular ideas about the fitness of things._________(48). But even an unpleasant truth is more than likely to be useful; besides we have the choice of refusing to believe it ! But hardly so with technology; we do not have the choice of refusing to hear the sound produced by a supersonic(超音速的) aircraft flying overhead; we cannot refuse to breathe polluted air._________(49)The purpose of technology is to serve people-people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves.
__________(50) Many people blame technology itself for widespread pollution, resource depletion(枯竭) and even social decay in general-so much so that the promise of technology is “ obscured “. That promise is a cleaner and healthier world. If wise applications of science and technology do not lead to a better world, what else will?
A Another distinction between science and technology has to do with the progress in each.
B Unlike science, progress in technology must be measured in terms of the human factor.
C What scientists discover may shock or anger people ---as did Darwin’s theory of evolution.
D Science and technology are different.
E We are all familiar with the improper use of technology.
F Science is a method of answering theoretical questions; technology is a method of solving practical problems.

Cost as a Factor in Supply
In a purely competitive market, the supplier of goods and services has no control over the market price, because he produces too little to influence market conditions. With no difference between his products and the products________(51) his competitors, he will sell nothing if he charges above the market price and he will sell all if he charges at or __________(52) the market price. However, in considering the price, he must take the ____________(53)of production into consideration. There are times when he may be willing to sell below his cost. This might happen when prices tumble for__________(54) he believes will be a short time. However, no business person can __________(55)to lose money for a prolonged period. He must be constantly __________(56)of his costs in relation to the market price if he is to competes successfully and earn a profit.
Many people have the impression that as production increases, costs per unit decrease._________(57)mass production has made this true in certain industries and at certain levels of production,________(58) logic and practical experiences have shown that costs per unit begin to rise beyond a certain level of production. Some economists_________(59)to this principle as the law of increasing costs.
The reason costs rise as production goes up is __________(60). However, it is easy to recognize that as production goes up, the need for additional factors of production will also grow,__________(61)competitive bidding in the marketplace for the factors of production. If a producer needs___________(62) skilled labor to produce more, and none of this labor is unemployed, the producer will have to get __________(63)from other sources. This can be done by ___________(64)higher wages. Higher bidding would also apply to the other factors of production. We must also recognize that not all labor is equally productive, ___________(65)not all land is equally fertile and not all ore(矿石)is equally rich in the mineral wanted.
