Look and predict
Look at the pictures and predict what the passage may talk about.
From ancient times when a cow could be traded for a horse, to the 21st century when that same horse might easily be bought with a bank card, humans have always needed a way to buy and sell things at an agreed price.
A system, like trading a cow for a horse, is called a barter system. It worked well for a long time. However, things became more complicated as the population rose. The daily life in such a world required a standard unit to measure the value of one thing against another. The era of money soon followed. And it has been with us ever since. Chinese people were the first to move from the bartering era to the money era. They began to trade shells for the products they wanted as early as 3,000 years ago.
Reading
Hundreds of years later, the Chinese began to use copper and bronze to replace the shells. According to research, the world’s first paper money, jiaozi, appeared in Chengdu in 1023.
In ancient Europe, around the 6th or 5th century BCE, money coins came into use. Unlike the Chinese, Europeans used precious metals such as gold and silver for their coins. Around the 17th century, paper money started to become more popular in Europe, because it was much easier to carry around and store.
This system worked until the early 19th century when the Bank of England introduced “gold-backed” paper money. If someone had this paper money, they could exchange it for a certain amount of gold or silver in the bank. This made people feel more secure because the paper money was connected to something valuable.

Match and talk
I know the value of money: Money is a medium of exchange. It means we can trade it for goods and service. While money is important, it cannot buy everything. Use money wisely and responsibly.
I adopt a healthy attitude towards money: Needs are things that we must have. Wants, on the other hand, are things that we desire but can live without.
Self-check
I understand how to spend and manage money wisely: It’s important to make smart choices with money.
I can give my opinions using attributive clauses: Money is something we use to buy things. There are many things that are even more valuable than money.
Improvement needed:
Money doesn’t grow on trees!
One, two, three, four, five, let’s count the coins I’ve saved tonight!
Six, seven, eight, nine, ten, can’t wait to save some more again!
One, two, three, four, five, let’s count the coins we’ve saved tonight!
Can’t wait to save some more again!
How did you get so much I made sure not to spend too much!
Money doesn’t grow on trees. So we need to spend it carefully!

长难句分析：该句为复合句。From ancient times和to the 21st century 为时间状语，里面包含两个定语从句，when a cow...修饰 ancient times；when that same horse...修饰the 21st century；主句humans have always needed...中，humans 是主语，have always needed 是谓语，a way 是宾语，to buy and sell things 是不定式作后置定语修饰way， at an agreed price 是介词短语作方式状语。
