Question

【题目】

People, animals, and other things make sounds (声音).

Sounds can be loud (大声的) or quiet, happy or unhappy.

Sounds are very important. Most people and animals use sounds, to communicate (交流) with each other. Many things also make useful sounds. Drums (鼓) and pianos bring us music. Bells in school tell us to have classes on time.

What is sound? Well, there is sound when an object (物体) vibrates (震动), or moves (移动) back and forth very fast. A vibrating object makes the air around it move. This is how sound travels. For example, when a driving car passes by, the air around it vibrates. When the vibrating air gets to your ear, you hear the sound of the passing car. We call the vibrating air sound waves (声波).

There are different kinds of sounds. Some sounds are loud. Others are quiet. The loudness of sound is called volume (音量). Very loud sounds are bad for your ears. Be careful around loud sounds. Cover your ears with your hands when you hear them, or move away from the loud sounds. When you use earphones to listen to music, make sure it is not too loud.

Sounds are everywhere in our life. Enjoy the sounds of the world and be careful with your ears!
