With no difference between his prod

14、ucts and the products of his competitors, he will sell nothing if he charges above the market price and he will sell all if he charges at or below the market price. However, in thinking over the price, he must take the cost of production into (27) and no business person can (28) to lose money for a

15、(29) period. He must be constantly aware of his costs in (30) to the market price if he is to competes (31) and earn a profit. Many people have the (32) that as production increases, costs per unit decrease. While mass production has made this true in certain (33) and at certain levels of production

16、, both logic and practical experiences have shown that costs per unit begin to rise beyond a certain level of production. Some economists (34) this principle as the law of increasing costs. The reason costs rise as production goes up is complex. However, it is easy to recognize that as production go

17、es up, the need for additional factors of production will also grow, (35) competitive bidding in the marketplace for the factors of production. If a producer needs more skilled labor to produce more, and none of this labor is unemployed, the producer will have to get it from other sources. Therefore

18、, offering higher, wages is the only way to encourage all labor to bee equally productive.（分数：71.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_九、Part Reading Compr(总题数：0，分数：0.00)十、Section A(总题数：1，分数：35.50)When a country is under-populated, newcomers are not competitors, bu

19、t assistants. If more come they may produce not only new quotas, but a (36) as well. In such a state of things land is abundant and cheap. The possession of it confers no power or privilege. No one will work for another for wages (37) he can take up new land and be his own master. Hence it will pay

20、no one to own more land than he can cultivate by his own labor, or with such aid as his own family supplies. Hence, again, land bears little or no rent; there will be no landlords living on rent and no laborers living on (38) , but only a middle class of yeoman farmers (非耕农). All are (39) on an equa

21、lity, and democracy becomes the political form, because this is the only state of society in which equality, on which democracy is (40) , is realized as a fact. The same effects are powerfully reinforced by other facts. In a new and under-populated country the industries which are most profitable ar

22、e the extractive industries. The characteristic of these, with the exception of some kinds of mining, is that they call (41) only a low organization of labor and small amount of capital. Hence they allow the workman to become (42) his own master, and they educate him to freedom, independence, and se

23、lf (43) . At the same time, the social groups being only (44) marked off from each other, it is easy to reliance from one class of occupations, and consequently from one social grade, to another. Finally, under the same circumstances, education, skill, and superior training have but inferior value c

24、ompared with what they have in densely populated countries. The (45) lie in an under-populated country, with the coarse. unskilled, manual occupations, and not with the highest developments of science, literature, and art.A. wages D. extractiveB. based E. speedilyC. substantially F. advantagesG. cul

ClocksAt best, historians know that 5,0006,000 years ago, great civilizations in t

26、he Middle East and North Africa started to examine forms of clock-making instead of working with only the monthly and annual calendar. Little is known on exactly how these forms worked or indeed the actual deconstruction of the time, but it has been suggested that the intention was to maximize time

27、available to achieve more as the size of the population grew. Perhaps such future periods of time were intended to benefit the community by allotting specific lengths of time to tasks. Was this the beginning of the working week?B. Sun clocks (1)With the disappearance of any ancient civilization, suc

28、h as the Sumerian (闪族人的) culture, knowledge is also lost. Whilst (同时) we can only hypothesize (假设) on the reasons of why the equivalent to the modern wristwatch was never completed, we know that the ancient Egyptians were next to layout a system of dividing the day into parts, similar to hours.C. Su

29、n clocks (2)“Obelisks“ (tall four-sided tapered monuments) were carefully constructed and even purposefully geographically located around 3,500 BC. A shadow was east as the Sun moved across the sky by the obelisk, which it appears was then marked out in sections, allowing people to clearly see the t

30、wo halves of the day. Some of the sections have also been found to indicate the years longest and shortest days, which it is thought were developments added later to allow identification of other important time subdivisions.D. Sun clocks (3)Another ancient Egyptian “shadow clock“ or “sundial“ has be

31、en discovered to have been in use around 1,500 BC, which allowed the measuring of the passage of “hours“. The sections were divided into ten parts, with two “twilight hours“ indicated, occurring in the morning and the evening. For it to work successfully then at midday or noon, the device had to he

32、turned 180 degrees to measure the afternoon hours.E. Water clocks“Water clocks“ were among the earliest time keeping devices that didnt use the observation of the celestial (天空的) bodies to calculate the passage of time. The ancient Greeks, it is believed, began using water clocks around 325 BC. Most

33、 of these clocks were used to determine the hours of the night, but may have also been used during daylight. An inherent problem with the water clocks was that they were not totally accurate, as the system of measurement was based on the flow of water either into, or out of, a container which had ma

34、rkers around the sides. Another very similar form was that of a bowl that sank during a period as it was filled of water from a regulated flow. It is known that water clocks were common across the Middle East. and that these were still being used in North Africa during the early part of the twentiet

35、h century.F. Mechanical clocks (1)In 1656, “Christian Huygens“ (Dutch scientist), made the first “Pendulum (钟摆) clock“, with a mechanism using a “natural“ period of oscillation (振幅) “Galileo Galilei“ is credited, in most historical books, for inventing the pendulum as early as 1582, but his design w

36、as not built before his death.G. Mechanical clocks (2)Huygens clock, when built, had an error of “less than only one minute a day“. This was a massive leap in the development of maintaining accuracy, as this had previously never been achieved. Later refinements to the pendulum clock reduced this mar

37、gin of error to “less than 10 seconds a day“. The mechanical clock continued to develop until they achieved an accuracy of “a hundredth-of-a-second a day“, when the pendulum clock became the accepted standard in most astronomical observatories.H. Quartz clocks (1)The running of a “Quartz clock“ is b

38、ased on the piezoelectric property of the quartz crystal. When an electric field is applied to a quartz crystal, it actually changes the shape of the crystal itself. If you then squeeze it or bend it, an electric field is generated. When placed in an appropriate electronic circuit, this inter action

39、 between the mechanical stress and the electrical field causes the crystal to vibrate, generating a constant electric signal which can then be used for example on an electronic clock display. The first wrist-watches that appeared in mass production used “LED“, “Light Emitting Diode“ displays. By the

40、 1970s these were to be replaced by a “LCD“, “Liquid Crystal Display“.I. Quartz clocks(2)Quartz clocks continue to dominate the market because of the accuracy and reliability of the performance, also being inexpensive to produce on mass scale. The time keeping performance of the quartz clock has now

41、 been surpassed by the “Atomic clock“ .J. Atomic clocks (1)Scientists discovered some time ago that atoms and molecules have “resonances“ and that each chemical element and compound absorbs and emits “electromagnetic radiation“ within its own characteristic “frequencies“. This we are told is highly

42、accurate even over “Time and Space“. The development of radar and the subsequent experimentation with high frequency radio communications during the 1930s and 1940s created a vast amount of knowledge regarding “electromagnetic waves“, also known as “microwaves“, which interact with the atoms.K. Atom

43、ic clocks (2)The development of atomic clocks focused firstly on microwave resonances in the chemical Ammonia and its molecules. In 1957, “NIST“, the “National Institute of Standards and Technology“, completed a series of tests using a “Cesium Atomic Beam“ device, followed by a second program of exp

44、eriments by NIST in order to have something for comparison when working at the atomic level. By 1960, as the outcome of the programs, “Cesium Time Standards“ were incorporated as the official time keeping system at NIST.L. Atomic clocks (3)The “Natural frequency“ recognized currently is the measurem

45、ent of time, used by all scientists, and defines the period of “one second“ as exactly “9,192,631,770 Oscillations“ or “9,192,631,770 Cycles of the Cesium Atoms Resonant Frequency“. From the “Macrocosm“. Or “Planetary Alignment“, to the “Microcosm“, or “Atomic Frequency“, the cesium now maintains ac

46、curacy with a degree of error to about “one millionth of a second per year“.M. Atomic clocks (4)Much of modern life has come to depend on such precise measurements of time. The day is long past when we could get by with a timepiece (钟) accurate to the nearest quarter hour. Transportation, financial

47、markets, communication, manufacturing, electric power and many other technologies have become dependent on super accurate clocks. Scientific research and the demands of modem technology continue to drive our search for ever more accuracy. The next generation of Cesium Time Standards is presently und

48、er development at NISTs “Boulder Laboratory“ and other laboratories around the world.N. Something to remember (1)The only thing that should be remembered during all this technological development is that we should never lose the ability to tell the time approximately by natural means and the powers of deduction without requiring crutches (拐杖) to lean on.O. Something to remember (2)Our concept of TIME and using it together with TECHNOLOGY still has r
