An individual place setting is called a cover 的中文意思是什么?

there are various ways in which individual economic units can interact with one another. three basic ways may be described as the market syste m, the administered system, and the traditional system.
　 　in a market system individual economic units are free to interact among each other in the marketplace. it is possible to buy commodities from other economic units or sell commodities to them. in a market, transactions may take place via barter or money exchan ge. in a barter economy, real goods such as automobiles, shoes, and pizzas are traded against each other. obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. hence, the introduction of money as a medium of exchange eases transactions considerably. in the modern market economy, goods and services are bought or sold for money.
　　an alternative to the market system is administrative control by some agency over all transactions. this agency will issue commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. central planning may be one way of administering such an economy. the central plan, drawn up by the ***, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. this is an example of complete planning of production, consumption, and exchange for the whole economy.
　　in a traditional society, production and consumption patterns are governed by tradition; every person’s place within the economic system is fixed by parentage, religion, and custom. transactions take place on the basis of tradition, too. people belonging to a certain group or caste（阶级） may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. an inactive society may result.

Handwriting reveals a great deal about how an individual thinks, since the brain dictate (发号施令) hand movements when a person writes. People who think quickly will write quickly, while people whose thinking is slow will write in the same way. Sometimes we see very elaborate (精致的) handwriting, particularly among public figures, such as actors or politicians, who want to draw attention to themselves. For them, handwriting is like a dress that enables them to stand out from the crowd.
The handwriting of someone who is suited to a routine job will appear well organized, clear, and regular, without any special features drawing attention to it. If the job requires proven accuracy, like that of an accountant(会计), the handwriting, especially the numbers, should be precise. On the other hand, someone in sales or public relations must be self-assured, know how to make a good impression, and be able to befriend people even when meeting them for the first time. The handwriting of such individuals will appear rather large, with elaborate capitals and on oversized signature. It will be quick, fluent, and not necessarily reasonable.
Handwriting analysis can be used to find potential behavioral or personality problems. People who are impulsive, aggressive, or dishonest write differently than those who are socially well adapted. Warning signs include broken and strongly or sporadically (零散的) pressured handwriting; disorderly handwriting in which the words run over the lines on the paper, or extremely sharp handwriting. Generally, handwriting that is extreme in any aspect-too small, too weak or too pressured-is suspect.
Evidence of medical problems also shows up in a person’s handwriting. Individuals in pain often stop in the middle of writing. Pauses will be visible in the handwriting of people who experience difficulty breathing, because they stop writing to take a breath.
Handwriting expresses the mental and physical state of the individual, as well. Depressed people write slowly, with lines sloping (倾斜) down and heavy pressure exerted(施加) on the page. People who are excessively excited will write quickly, and their handwriting will be extremely disorganized and practically unreadable. People who are tired tend to write lines that descend down the page, and their handwriting will appear weak and slow. Healthy and vigorous individual will write energetically, and their handwriting will be quick, rhythmic and fluent.
