Do you know how long it’s been since mobile phones were first invented? On April 3, exactly 42 years ago, the first public call ________ (make) from a hand­held wireless phone.

Martin Cooper, a US researcher at Motorola, made the call from a corner in New York City in 1973.

People were very surprised at the phone, Cooper remembered. ＂We caused a great stir,＂ he said.

The phone was a big thing by today’s standards—it weighed almost 1 kilogram and was about 25 cm long. Now, mobile phones fit into the palm(手掌) of your hand and weigh a little more than a lemon.

But back then, it was a huge advancement, especially when compared with the car mobile phones that had been in use since the 1940s.

A car phone weighed more than 13 kilograms and cost thousands of dollars. An owner had to drill(钻) a hole in the car just to fix it.

At that time, Cooper was competing with Joel Engel, the head of research at a rival wireless communications company. So, he made the first call to him.

＂I told him, ‘Joel, I’m calling you from a real cell­phone’,＂ said Cooper. ＂I thought I heard gnashing of teeth(咬牙切齿) at the other end, but he was polite.＂

Since that first call, billions of people around the world have owned mobiles.

Today, they are multifunctional(多功能的) with more and more features(特征), like short text messages, cameras and MP3 players. And people can also use them to get online.

However, Cooper still believes the ＂original dream＂ of a true mobile phone call is not yet a reality. That is: being able to use a phone to call anyone from anywhere. Cooper’s dream phone is so small that it fits behind his ear and automatically(自动地) dials out when he thinks about calling someone. And when there is an incoming call, it tickles(使发痒) instead of ringing.

Mobile phone history

Not long ago, mobile phones were used mainly by business people and government officers in society. In the US, mobile phone users were about 340, 000 in 1985. Now there are 205 million mobile phone users in the US. Studies also show that over 50 percent of children in the US own their own personal mobile phones. The mobile phone explosion(激增) has led to a huge number of waste phones. The number of mobile phones users has also increased throughout the world. In the middle of 2005, the number of total users jumped to 2.4 billion worldwide.

Mobile phone waste

When people throw their mobile phones away, they usually end up in the open air. Mobile phones include some materials like lead, mercury and cadmium. They can go into public drinking water and food and do harm to people’s health. About 75 percent of mobile phone users don’t throw their phones away. Instead, they prefer to keep the waste ones sitting around the house as they are not worth very much. People are also afraid that others may know their information if they sell their waste phones. Less than 20 percent of them are recycled each year.

Benefits(益处) of recycling mobile phones

Mobile phones have valuable materials inside. The most valuable material is gold, which is used in the phone circuit boards. Recycling can reduce greenhouse gas emissions (排放物) and keep natural resources like gold. If all of the waste phones in the US are recycled, it will save enough energy to offer over 194, 000 U.S. families electricity(电力) for one year.

How mobile phone recycling works

Many people do not know how mobile phone recycling works. One method of recycling mobile phones is to take the working parts of broken phones, then combine(使结合) them with the working parts of other used mobile phones to make one ready-to-use mobile phone. Another method of mobile phone recycling is to melt(熔化) down and separate parts of the phone, getting the valuable natural resources, such as gold and platinum. Plastic and glass can also be recycled from used mobile phones.

Do you live in a city? Do you know how cities began? Long long ago, there were only a few thousand people in the world. These people moved from one place to another. They moved over the land, hunting animals for food.

No one knows how or when these people learned about growing food. But when they did, their lives changed. They did not have to move any more.

They could stay in one place and grow food there. People began to live near each other, so the first villages appeared. Many people came to work in the villages, and these villages became larger and larger.

Later people had machines. Life in the villages changed again. People built factories. More and more people lived near the factories, so the villages grew into cities. Some of them grew very big.

Today, it's strange that some people are moving back to small villages. Can you tell me why?
