We know music is very important in our daily (日常的) life. Do you notice music playing in many places? Today we hear music in most stores, stations, restaurants and other places. We can also hear music in an office or on a farm. Scientists believe that music influences (影响) people's behavior (行为).
They think that the sound of Western classical music makes people feel richer. When a restaurant plays classical music, people spend more money on food and drinks. When the restaurant plays modern music, people spend less money. Without music, people spend even less.
Scientists also think that rock music makes people eat faster. Some restaurants play fast music during their busy hours. This makes people eat faster and leave quickly. Restaurants can make more money in this way.
Some scientists think that music makes you think and learn better. They say that music helps students to be more active (活跃的). It is true that people learn better when they are relaxed. And listening to music can help you relax.
