　　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)

　　Useful Words and Expressions:

　　matter n.物质;内容;事情

　　reading matter阅读材料

　　This is a matter of no account.这是一件无关紧要的事。

　　I have an urgent matter to atend to.我有一件急事要办。

　　I have an important matter to talk to you about.我有件重要的事要和你谈谈。

　　destructive adj.破坏(性)的

　　seismic adj.[地]地震的

　　seismic waves震波

　　bounce v.(使)反跳，弹起

　　bounce back弹回

　　vacuum n.真空立
