Did you ever count the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That’s because China has the longest mobile phone numbers in the world. Why is that?
We can group the 11 digits into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service company you are using. For example, 135 is for the China Mobile Communications Corporation (中国移动) and 188 is for China Unicom (中国联通). The fourth to the seventh digits tell you where the number is registered (注册).For example, 0731 shows it is registered in Changsha, and 0733 shows it is registered in Zhuzhou. And the last four digits are random (随机的).
The main reason for using 11 digits is that we have the most people in the world. We once had 10 numbers. But as people grew more and more, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999.
We can use eleven digits to make uncountable mobile phone numbers. That’s enough for each person to have seven or eight phone numbers to use in China.
What’s more, we can recycle mobile phone numbers. Usually, if someone doesn’t use the number any more, the service company will reuse the number after three to six months. If you didn’t call a number for a long time, you may find that the owner already changed.
Like China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada’s mobile phone numbers are probably the world’s shortest: they use seven digits.
1.When you see the phone number 13507336688 in China, you may get the following information EXCEPT （除了） .
A.the service company is China Mobile Communications Corporation
B.the last four digits 6688 tell us where the phone number comes from

2.China has the longest mobile phone number mostly because .

The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider (提供者) you are using For example, 135 is for China Mobile Communications Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注册). And the last four digits are random (随机的).
The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use.

Eleven digits can be used to make tens of billions of mobile phone numbers.83That’s enough for each person to have seven or eight phone numbers to use in China.

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?
