A mobile phone（手机）is in fact a small radio. A radio sends a person's voice over a long way to another radio. A voice that is sent by radio is called a signal（信号）. A radio signal travels very quickly.

　　Only a few years ago, mobile phones were very large. They needed large batteries（电池）. They had to be powerful（功率高）to send their signal to faraway places. This was because most cities had only one antenna tower（中继站）for mobile phones.

　　Today's mobile phones are small and easy to use. Now most cities have a lot of antenna towers, not just one. This means that each mobile phone doesn't have to send its signal far away, so they don't need to be so powerful. Mobile phones today use small batteries. A large city, where lots of mobile phones are used, can have hundreds of towers.

　　Do you know what use a mobile phone has? Yes, you can use it to do a lot of things.

　　Call your friends and family from almost anywhere.

　　Call the police immediately if there is an accident in the street.

　　Send or receive e-mail.

　　Get information from the Internet.

　　Send and receive messages.

　　Sending short written messages is a popular way to use your mobile phone. Many people use short forms of words, so the messages are quick to write and read. Can you guess what these messages mean? Try reading them out. What do you hear?
