Waves

How does light get from the sun to the earth? How does music get from the stage to the audience? They move the same way —in waves!

Light and sound are forms of energy. All waves carry energy, but they may carry it differently. Light and sound travel through different kinds of matter. For example, light waves cannot move through walls, but sound waves can. That is why you can hear people talking in another room even though you cannot see hem. The energy of some waves is destructive. An arthquake produces seismic waves.

Catch a wave. Ask a friend to stand a few feet away from you. Stretch a spring between you. Shake the spring to transfer energy to it. What happens? The spring bounces up and down in waves. When the waves reach your friend, they bounce back to you!

Light waves travel 300,000 kilometers (186, 000 miles) per second! They can also travel through a vacuum. That is why light from the sun and distant stars can travel through space to the earth! (175 words)

Finding the Direction and Location

How can you tell which direction? By day, look for the Sun. It is in the east in the morning and the west in the afternoon. At night, use the Big Dipper to help you find the North Star. It would be better to bring a compass because its needle always points north.

How do you know how far you have gone? You could count every step. Each step is about two feet. You’d better wear a pedometer which is a tool that counts steps. If you know where you started, which direction you are heading, and how far you have gone, you can use a good map to figure out exactly where you are.

Today there is a new way for travelers to figure out where they are. It is the GPS. It has 24 satellites that orbit the earth and constantly broadcast their positions. Someday you may carry a small receiver as you hike and use GPS to find out if you are there yet! (167 words)

dipper n.北斗七星

compsiss n.罗盘，指南针，圆规 v.包围

Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. At the end of each news item, you will be given 10 seconds to answer the questions.

听力原文： The cancellation of the 16-day flight means that the crew and scientists on the ground are pursuing only their most important experiments in the few remaining hours left before the shuttle laboratory is closed. The US sapce agency NASA decided Sunday to bring the orbiter home 12 days early because of fears of weakened power generator could explode. The generator has been turned off, leaving the shuttle with only two thirds of its normal power supply. To conserve electricity for the experiments the crew is working in dimmer lighting than normal and has turned off all unessential equipment. NASA says the two remaining generators are sufficient for Tuesday's landing, but had nevertheless ordered the astronauts to study emergency procedures in case another fails. The shuttle team has expressed its disappointment at the curtailment of the science mission, and says enough data have already been collected in the materials, combustion and biological experiments to push science further ahead. The scientist' goal is to complete the experiments on a later shuttle flight. David Batlery, VOA news, Washington.

Why did NASA decide to bring the shuttle home earlier?

A．The laboratory was closed.

B．The generator was turned off.

C．The power generator might explode.
