At present, almost everyone has a mobile phone, but have you ever thought that cell phones 　 　　　 　 be bad for your health? A study shows that heavy mobile phone use may cause hearing loss.

This study shows that people who use cell phones for about an hour a day have a 　 　　　 　　 time hearing some similar sounds, especially in their right ears. It is getting harder for 　 　　　 　 to tell the difference between the sounds of “s” and “f”, and “t” and “z”.

Researchers studied 100 people who used cell phones and 　　 　　　 　　 them with 50 people who did not. The study lasted for 12 months. What the researchers found was that cell phone users had more hearing 　　 　　　 　 than those who did not use cell phones.

Besides this, our ears have many little 　　 　　　 　 inside them. Too much noise will cause these hairs to get weak and 　　 　　　 　　 die. When these hairs die, it affects our ability to listen.

However, cell phone users don’t care too much 　　 　　　 　 this study. One man said, “I’d be more worried about people who 　　 　　　 　　 MP3 players. They put those earphones in their ears and listen to very 　　 　　　 　　 music. I think that is more likely to cause hearing loss than a cell phone.”

Have you ever counted 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?

The 11 digits can be divided into three parts. Each pare has a different meaning. The first three numbers tell you which mobile phone service provider 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 which region the number is registered (注册) in. 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. So we began to use 11 digits starting from 1999.

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

Plus, mobile phone numbers can be recycled. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven’t contacted for a long time, you may find that its owner has changed.

Besides 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 perhaps the world’s shortest: they use seven digits.

1.Which country has the longest mobile phone numbers in the world?

____________________________does.

2.What can we know from the first three digits of a phone number?

The first three digits stand for_____________________.

3.Why does China use 11 digits for phone numbers?

Because___________________________.

4.When can a phone number be recycled?

The service provider will ___________________________.

5.Do Canadians have the world’s shortest mobile phone numbers?

Almost everyone has a piggy bank (储蓄罐), but did you ever wonder why people often make it in the shape of a pig?

Believe it or not, people made the piggy bank in the shape of a pig by mistake. In the Middle Ages, many containers (容器) at home were made of a kind of cheap clay (陶土) called pygg. The word “pygg” sounds the same as “pig”. At that time, there weren’t banks like we have today, so people would save their money at home in some clay containers. Because the kind of clay was called pygg, people called the containers pygg banks. Over time this became piggy banks. After several hundred years, people forgot that the word “pygg” meant a kind of clay.

The English language also changed. People used the word “pig” more commonly. So when English workers were asked to make “piggy banks”, they thought they needed to make containers in the shape of pigs. Surprisingly, the pig-shaped containers were popular.

Today piggy banks are made of all kinds of things, and they also come in different shapes and animals. But people still call those cute containers for money piggy banks.
