When it comes to economics, it may be felt that we are far from living, but in fact, much of our life is linked to economics. To this end, heilongjiang provides: the 2020 national examination of common sense: economics in life, as follows. More information on the national examination may be useful to focus on the public service examination channel of the central and southern heilongjiang。
In the area of common sense judgement, the content of economics often emerges, and we all know that the economic base is an important part of sustaining our daily lives, but when it comes to the economy, it may be felt that we are far from our lives, but it is not. Much of our life is linked to the content of economics. The chinese public education experts are here to talk to you。
For example, do you know why milk is in a box and coke is in a cylinder? First, because drinks are usually open for direct drinking, but not milk, so milk is in a paper box. Second, the storage of drinks is sufficient, but milk needs to be placed in an icebox, so milk is used in cheaper paper boxes. Finally, since milk is placed in a freezer, there is a waste of space in the shape of a circle, so a square paper box is used. Understand?
Let's see one more. Do you know why the restaurant is offering a free refill? This applies to one of the principles of economics, called marginal costs, which must be higher than the marginal cost of the meal per meal (the marginal cost is the increased cost of workers ' wages, raw materials and fuel, etc., needed to increase production per unit at any level of production), so that the profitability of the restaurant increases as long as it attracts additional hospitality. To put it bluntly, we do not need to increase some of the costs, such as additional workers ' wages, while enjoying free refills of drinks, and will probably increase incomes for other commodities in restaurants。
Now, let's see how the calendar question is about economics!
1. The phenomena described in the following proverbs correspond to the economics noun:
Unrecoverable water — opportunity costs
One mountain is not worth two tigers — total monopoly
C. Entering the room of zeran for a long time without hearing its fragrance - the marginal effect is diminishing
D. Fire at the gate, affecting the fish pool — negative externalities
In item a of the [central public analysis], the opportunity cost is the maximum value of what is to be given away in order to obtain something. The word “crash” means that the water that has fallen on the ground is difficult to recover, and it is a metaphor that the matter is settled and irreversible. There was no correspondence between the two, so item a was wrong。
In item b, total monopoly refers to the market structure of only one producer in the entire industry. The term “one mountain must not be two tigers” means that a mountain cannot live with two tigers at the same time. The two are reciprocal, and item b is correct。
In item c, marginal utility is the increase in utility per unit of consumption, while marginal utility is decreasing, meaning that the marginal utility of an item is decreasing over a period of time as the number of items consumed increases. "long without hearing its scent" means that for a long period of time, the smell of the orchids can be felt because of the fumigation itself. The two are reciprocal, c is correct。
Item d, negative externalities, refers to the economic phenomenon in which certain enterprises or individuals are adversely affected by the economic activities of other enterprises and individuals without being compensated for by the enterprises and individuals responsible for these effects. “fire in the gates, fish in the pond” means fire in the gates, and everyone goes to the moat to fetch water, the water runs out and the fish dies. It is a metaphor that has suffered loss or a scourge as a result of being associated. The two are reciprocal, and item d is correct。
So the result of this question is option a。
These are the economic principles of common sense that are briefly presented to you, and it is hoped that you will be able to learn more about the accumulation of life and be active in preparing for the common sense component。
