Economics is the study of how people make choices to satisfy their unlimited wants with limited resources.
经济学是研究人们如何在资源有限的情况下做出选择以满足无限欲望的学问。
The basic economic problem is scarcity – the situation where there are not enough resources to produce all the goods and services that people want.

商品可分为消费品（个人使用）和资本品（用于生产其他商品）。
Most economies produce a combination of goods and services to meet the needs and wants of the population.
大多数经济体同时生产商品和服务以满足人民的需要和欲望。
4. Factors of Production | 生产要素
The factors of production are the resources used to produce goods and services. They are commonly grouped into four categories: land, labour, capital and enterprise.
生产要素是用于生产商品和服务的资源，通常分为四类：土地、劳动、资本和企业家精神。

机会成本是做出一种选择时所放弃的次优替代品的价值。
Because resources are scarce, every decision involves sacrificing something else.
由于资源稀缺，每个决定都涉及牺牲其他东西。
For example, if a government spends more money on building roads, the opportunity cost might be fewer hospitals or schools.
例如，如果政府把更多钱花在修路上，机会成本可能是减少医院或学校。
Individuals also face opportunity costs: choosing to spend an hour playing video games means giving up an hour of study time.
个人也面临机会成本：选择花一小时玩电子游戏意味着放弃一小时的复习时间。

8. Barter and Money | 物物交换与货币
Barter is the direct exchange of goods and services without using money. It requires a double coincidence of wants – each party must have what the other wants.
