2 . Long ago, people did not need money. They lived on wild animals, fruits and other plants. As time passed, people learned to raise animals and crops. Sometimes, families produced more than they needed, so they started to trade with other families. Later, people began to use money as a means of exchange. However, it was not the kind of money we use today. They used shells, rice, salt, large stones, etc.
During the 600s B.C, people began using coins as money. They soon found that they were easier to carry than goods and lasted a long time. Later, countries began to make their own coins.
The Chinese were the first to use paper money, probably as early as the 11th century. The Italian traveler Marco Polo saw the Chinese using money when he visited China in the 1200s. However, European countries did not start using paper money until 1600s.
Today, we have many ways to pay for things. We do not use coins or paper money. Often, people prefer to pay for things by card. Paying with a card is easier and safer than carrying around a lot of “real” money.

3 . The People’s Bank of China has issued (发行) the fifth edition (版本) of the renminbi (RMB). These paper money has brighter colors and new safety ability.
We’ve been using paper money for around 1,000 years. Back in the Northern Song Dynasty, Chinese people made the world’s earliest paper money to take the place of the metal coins. They were called jiaozi.
Paper money was cheaper to make and easier to carry. These advantages made it more popular than other forms of money. But now, in the digitals (数码的) age, paper money seems to be disappearing for the same reason.
Now, from supermarkets to street stores, people pay by using the Wechat Wallet and Alipay apps on their mobile phones. Sweden is even closer to a future without paper money. Many Swedish banks no longer even have cash (现金) on hand.
But there are worries about creating cashless societies. Some say it is unfair to the poor and people without much education. It’s not easy for them to open bank accounts (账户) or deal with mobile phones. And if all of your money is “digital”, it may not be safe enough.
Is paper money going away? Although paper money is used less than electronic payment in some countries, it won’t disappear at once in most parts of the world.

5. What does the writer want to tell us in the last paragraph?
In many places, wildfires destroy（毁灭）thousands of square kilometers of forest and farmland each year. They can spread out of control and put homes and sometimes whole towns in danger. To keep the homes and towns safe, wild grass and brush（柴枝）must be cleared. This need has led to an interesting solution（办法）, which has many advantages.
First, goats and sheep spend all their time eating grass. When they arrive in an area, they can clear an acre（英亩）in as little as three days. Besides, they are more environmentally friendly than machines, and they can clear grass on hills where people and machines cannot arrive.
Goats have been widely used in California for clearing brush around farms, neighborhoods, and cities. An example is the city of Anaheim, which is home to Disneyland. The city uses goats to clear the nearby hills all year round. The goats can have their stomachs filled, and the city can be out of danger. It is really a win-win!

You can tell which planet is Mars because it is bright red and looks like a red and orange ball in the night sky. It’s very beautiful. But during spring and summer, the surface of it is covered by strong storms. The gravity（重力）on the surface of Mars is about 2/5 as strong as it is on the earth. So a person who weighs 90 kilos on earth weighs only 36 kilos on Mars. The temperature on Mars is between -138℃ and 28℃. The air has only 0.13% oxygen.
