In 1870, homes and mules were the prime source of power on U.S. farms. One horse or many decades. At that time, had a national commission been asked to forecast the horse and mule population for 1970, its answer probably would have depended on whether its consultants were of an economic mm of mind. Had they been "economists", they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that would be only a matter of time before steam would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.
Which of the following is NOT mentioned by the author as a consequence of new technological developments？
A．Older technologies die away.
B．The quality of life is improved.
C．Overall productivity increases.
D．More raw materials become necessary.
In 1870, horses and mules were the prime source of power on U. S. farms. One horse or mule was required to support four human beings—a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the horse and the population for 1970, its answer probably would have depended on whether its consultants were of an economic or technological turn of mind. Had they been "economists" , they would probably have projected the 1970 horse or mule population to be more than 50 million. Had they been "technologists", they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that it would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.
According to the passage, what supplied most of the power on U. S. farms in 170？
A．Animals.
B．Humans.
C．Engines.
D．Water.
所谓货币流通速度V是指实际GNP与实际货币持有量的比率，V=Y/(M/P)。请利用等式(14-4)推导货币流通速度的表达式，并解释货币流通速度是如何随R和Y的变化而变动的。(提示：产出变化对v的影响取决于相对于实际产出的货币总需求弹性，经济学家认为该弹性小于1。)货币流通速度与汇率之间存在什么联系？
The velocity of money，V，is defined as the ratio of real GNP to real money holdings，V=Y/(M/P)in this chapter's notation．Use equation(14-4)to derive an expression for velocity and explain how velocity varies with changes in R and in Y．(Hint：The effect of output changes on V depends on the elasticity of aggregate money demand with respect to real output，which economists believe to be less than unity．)What is the relationship between velocity and the exchange rate？

Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.
People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.
This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.
What is this passage primarily concerned with？
A．The problems caused by economic growth.
B．The desirability of economic growth.
C．The desire for more material wealth.
D．The limits of economic growth.

Some economists believe that taxes have an important effect on labor supply. They argue that higher taxes cause people to want to work less and that lower taxes cause them to want to work more. Consider how this effect alters the macroeconomic analysis of tax changes.

d．What is the long-run impact of a tax cut on output and the price level？ How does your answer differ from the case without the labor-supply effect？
A.more efforts shouldBe made to improve the quality of our material life
