It's so quiet in the classroom that you can hear the needle fall to the ground.
In order to express strong thoughts and feelings, highlight the essential characteristics of something, and use rich imagination to deliberately exaggerate or narrow some aspects of things for artistic rendering.
Extended data:
In order to achieve a vivid and humorous effect, we often artificially raise the characteristics of things to make them higher, stronger, faster and more, and even achieve an overwhelming and earth-shattering magical effect.
Reducing exaggeration is the antonym of enlarging exaggeration. This kind of exaggeration is to deliberately make ordinary things smaller, lower, weaker, slower and less, so as to achieve the effect of shrinking several times. For example, "it's so quiet in the classroom that you can hear a pin drop to the ground." Is to reduce the use of exaggeration.
