The second day physics composition silent world 500 words original urgent! ! !

The silent world is terrible, there will be no sound in the silent world, just like a bottomless pit!

The Silent World has many shortcomings, such as:

1, if the car comes from a distance, it will hit someone if it doesn't honk.

When people are talking, they can't hear a person talking, but they can't understand what they are saying only when they see people moving their mouths.

In short, there will be no good things in a silent world, but a world with sound is better.
