In our colorful world, sound plays an important role. What would the world be like without sound? Let's imagine what kind of world it would be. Is it interesting? Cold? Quiet? Or is man the master of the world? What effect will sound have on human beings first? Then let's talk about the influence of sound on human beings first! What will happen to human beings if there is no sound? If there is no sound, people can't make a sound when they speak, just like people who lose their voices speak in sign language. Why do people need ears? There is no sound to listen to. Is it for decoration? How can there be such beautiful music now? If there is no sound, what is the point of the whole world dying in a dead universe? If there is no sound, how can students study and read at school? How can there be music, English and information courses? How will you express what you want to express? Do you rely on sign language? I really can't imagine what teaching would be like at that time. Pangu, the ancestor of China, created human beings because he thought the world was too quiet and lifeless. Now, if there was no sound, there would be no laughter. Then why are there humans? What's the point of having humans? We are not Beethoven, nor do we have Beethoven's skills. Even if we can't hear, we can bite a stick with our teeth and feel the sound according to the vibrating skull. But if there is no sound, not even sound waves, even Beethoven can't feel the sound, let alone play the piano. If there is no sound, how can there be a telephone now? If relatives are far away, how will they talk? Can you sign language after such a long distance? If there are too many ifs, I think these ifs are impossible. In short, human beings need sound. It's hard to imagine how human beings would survive without sound! Of course, this is not just human beings; Animals also need sound, and even animals can't live without sound; For example! Bats can be said to be a special kind of animals. Although it has a pair of eyes, it can always see if it can't hear, but do you know it is called "blind" in the animal kingdom? Its eyes are not worthy of the name, because it relies on its ears. Listen to ultrasonic waves with your ears to identify positions and avoid obstacles. If there is no sound, the bat can't hear the sound, can't catch the food and can't fly, then does it still have a chance to survive? Of course, bats are not the only animals, and other animals cannot do without sound. Here is an example to emphasize that "the earth cannot live without sound". Without sound, people seem to live in a vacuum, quiet and silent. There is no wind, no rain, no reading, but more birds, songs and laughter. Therefore, the universe in which human beings live now has no color and no sound.
