Only a few years ago, mobile phones were very large. They needed large batteries. They had to be powerful 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.
We can use a mobile phone to do a lot of things, like calling your friends and family from almost anywhere, calling the police immediately if there is an accident, sending or receiving messages. Some modern mobile phones can be even used to play games, take photos, listen to music, watch TV, surf on the Internet and so on.
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? RUOK? CUL8r! That’s EZ! That’s Gr8! Can I C U B4 3pm 2moro? Try to read them out. What do you hear?
