Counting before numbers

Before the invention of written numbers, people used many different ways to count things.

At first, people used their fingers, and even their toes. However, they could only count small numbers in this way.

After that, they began to make small marks on sticks and bones. This helped them count bigger numbers. They used them to count things like the days of a month, the amount of food and the number of animals they had.

Then people began to use tokens made from clay or small stones. This helped them count even bigger numbers. They often put the tokens on pieces of string so that they could carry them around easily. This developed into tools like the abacus.

Finally, people began to develop systems of written marks to show different numbers, and this led to the Hindu- Arabic system (0-9). We are still using this system today.

【1】Did people use many ways to count things before written numbers were invented?

【2】What did people use to count small numbers at first?

【3】Why did people put the tokens on pieces of string?

【4】How many ways of counting are mentioned(提到) in this passage?

【5】Which appeared earlier, the abacus or tokens?

【題目】 How much pocket money do you get? How do you spend it? The Blue Book of Chinese Teenager Financial Study shows that social （社會的） activities now take up more of teenagers' spending. The book was about teenagers' spending habits. It was based on studies in nine cities in China, such as Beijing, Shanghai and Guangzhou. The results show that students are spending more and more on their relationships with friends and classmates, such as having meals together and buying birthday gifts. Only one-third of high school students think about the price when choosing gifts. Most say they only care about what their friends like.

Xiao Hao, 17, a student at Gaoyou Normal School in Jiangsu, spent more than 1,000 yuan on his birthday meal this February. “They had given me gifts. If I hadn't done anything in return, I'd have lost face,” Xia said.

Xia's experience is quite usual among the young students. A meal can cost a student's pocket money for a month. Many just ask more from parents when they use up their money.

Zhang Wei, an expert on teenagers' financial study, suggested that teenagers should learn to make a budget. A budget is a plan of how money will be spent. It helps make decisions about money. To make good use of your money, you can also set a limit （R#d）. Learn to balance your wants and needs. When choosing gifts for friends, let them know that you care. Sometimes a handmade gift is much better than an expensive one.

【1】Were there only three cities in China taking part in the study?

____________________________________________________________________________________________.

【2】According to the results, how do students spend most of their pocket money?

They spend most of their money _______________________________________________.

【3】Which do most students consider when choosing a gift, the price or the things their friends like?

【4】Why did Xiao Hao spend much money on his birthday meal?

【5】How much can a meal usually cost among the young students?
