1
Money.
2
It's one of the greatest creations of human history and has played a positive role in the development of modern civilization.
3
However, we haven't always used money.
4
If we look back, say, more than 3 ,000 years ago, which is when coins first appeared,
5
we would find that most people conducted business using a system of direct exchange called barter.
6
For instance, I might exchange my five chickens for your three sheep.
7
That's barter.
8
Today, I'll be talking about some advantages of money over barter, how money has undergone change over time, and the benefits of money.
9
Okay, in early societies, land and agriculture provided the main forms of wealth and power.
10
How?
11
Because only landowners could grow large amounts of food and raise large amounts of animals, such as cattle and sheep.
12
Although people could carry out limited business transactions by bartering animals and vegetables, the barter system was doomed to fail.
13
Why?
14
Well, you'll see through the four enormous advantages of money I'm about to explain.
15
The first advantage is that financial transactions of any size can take place,
16
an advantage that increased tremendously when paper money was introduced.
17
For example, it's simple for a company to make a transaction involving millions or billions of dollars when using money.
18
Second, transactions involving money can be done fast.
19
People who have money can get it and transfer it to another person rapidly.
20
This means that business can be conducted quickly.
21
And now, of course, with electronic transactions, money can be moved over any distance in a flash.
22
Third, money allows people to do business with anyone, across cultural or geographic boundaries,
23
and this greatly expands business opportunities.
24
Money truly enjoys universal acceptance.
25
The fourth advantage is that the value of money is precise and consistent.
26
Precise means that the value of money can be determined in exact ways,
27
$5 .49 or $5 .51 sense.
28
Money is also consistent because the value of one dollar is one dollar.
29
It isn't subjective.
30
And even when the value of a currency fluctuates, it fluctuates for everyone.
31
Okay, let me say a few words about the evolution of money.
32
Originally, money was a physical object found in nature, cattle and grains for example.
33
It then evolved to become a manufactured physical object, such as gold and silver coins.
34
Next, money became something more abstract, something that is symbolic of physical objects such as gold and silver.
35
At this stage in its evolution, money became pieces of paper, such as paper money and stock certificates.
36
While gold and silver coins have real value, paper doesn't because it's completely separated from what it once represented, gold.
37
This was an enormous evolutionary leap because money moved from being a concrete, physical object to being a symbolic, abstract idea.
38
And this This idea worked only because people had a great deal of trust and faith in the principle.
39
Okay, now what about the benefits that have resulted from the invention of money?
40
I'll cover three.
41
The invention has benefited commerce, human initiative, and individual freedom.
42
Traditionally, wealth was handed down from parent to child in the form of land.
43
And because few people were landowners, few people had any hope of advancing in society or of becoming even moderately wealthy.
44
However, as agriculture became increasingly efficient, more and more people abandoned farm work.
45
These people began to live in cities, and to make their livings by offering non -agricultural products and services.
46
Money was the facilitator of this commerce because, as we just saw, money allows business people to sell goods to anyone, right?
47
Second point, the rise of commerce increased individual initiative because wealth was no longer necessarily tied to heredity.
48
Instead, brains and hard work became important.
49
The result?
50
Growing middle class and upper classes of relatively wealthy people.
51
And thirdly, people working in non -agricultural businesses gained the freedom to choose their own futures.
52
For example, education became accessible to many more people.
53
As a result, they were better able to function independently and successfully.
54
This further accelerated the growth of both new businesses and money.
55
Can you see that?
56
All right, to sum up, money is one of the greatest and most productive tools ever created by human beings.
57
It's a tool that's strongly related to human and social development,
58
to creativity, and, frankly, to turning dreams into reality.
59
But the true source of all of these benefits is not money itself, because money is just an abstraction.
60
Humans are the ones who give meaning to money, and through this very human use of trust and faith,
61
millions of people have been able to live better, more comfortable, and more fulfilling lives.

影子跟读练习技巧
英语影子跟读（shadowspeaks）是提升口语流畅度的有效方法。本节视频语速适中，语调平稳，适合作为影子跟读素材。练习时，可先逐句播放，滞后1-2秒跟读，重点模仿连读与重音，如“financial transactions”中的连读，以及“enormous advantages”的重音位置。对于较长的句子，如“Money allows people to do business with anyone, across cultural or geographic boundaries”，可拆分结构，先跟读分句，再整合。多次练习后，尝试同步跟读，感受语流节奏。坚持通过影子跟读（shadow speech）训练，不仅能强化听力，还能提升口语的自然度与准确性。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
