11.When kids hit puberty(青春期),their bodies and minds go through tons of changes,including the larynx,the voice box in the throat.The larynx is what gives you your voice.You can find your larynx by touching the front of your throat and humming.When you feel vibrations(震動) under your fingers,you've found it!
When the larynx grows larger during puberty,it sticks out at the front of the throat.This is what's called an Adam's apple.Everyone's larynx grows during puberty,but a girl's larynx doesn't grow as much as a boy's does.That's why boys have Adam's apples.Most girls don't have Adam's apples,but some do.
But why is it called an Adam's apple?If you think it's called that after the story of the Garden of Eden where Adam ate a piece of the forbidden fruit that got stuck in his throat,you're right.An Adam's apple sometimes looks like a small,rounded apple just under the skin in the front of the throat.
This larger larynx also gives boys deeper voices.Actually,girls'voices get a little bit deeper as their larynxes get larger,too.But because boys'larynxes grow so much more,it makes their voices deeper than girls'voices.
The larynx doesn't grow to its new size overnight,though.If you've ever heard a teenage boy's voice sound squeaky(發(fā)短促尖叫聲的),you've heard a larynx trying to get adjusted to its new size!
