The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are small and light and you do not need much space for them. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can only buy telephone cards, and some cards cost up to ￡4,000.The first Japanese card has a value of about ￡28,000. Most people only see cards with prices like these in their collectors' magazine.

Air is a colorless, tasteless and invisible（看不见的）gas that is around us. An "empty" drinking glass and an "empty" room, in fact, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.

Air, as a gas, has no definite shape, but because it is matter, it takes up space and it has weight. It is easy to prove that air is something that takes up space. Stuff a piece of dry cloth（布）into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside down glass, holding straight up and down, into a jar of water till the glass is completely covered. When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.

New Science and Technology

Look carefully before you cross

The city of Daye in Hubei Province is using new technology to stop people from crossing against red lights. The city has set up special posts (杆) on its sidewalks. The posts can recognize (识别) human faces. If they catch a person crossing at a red light, they will send water drops at him or her.

High-tech building

China not only builds things quickly, but also tries to use new and high technology. About twelve years has passed since the opening of the Qinghai-Tibet Railway. About 550 kilometers of the railroad runs over ice-covered earth. When the ice-covered earth gets warm during summer, it can make the railway move. Chinese scientists built special structures to solve this problem.

Musical road in Holland (荷兰)

In a village of Holland, there is a musical road. With the help of something special, the road can play a song. But if a car drives at a speed of over 60 km/h, the sound will become noisy. The local government thinks it will encourage drivers to control the speed. They will have to slow down in order to hear the song instead of the noise.

How green are you？Do you know how to be green？

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

Reduce

Reduce means" use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary﹣or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

Reuse

Reuse means" use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup of a paper bag. It's better to use a china cup and a lunch box because you can use them again.

Recycle

Recycle means" change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

So please remember these three words: reduce, reuse and recycle.
