Together, they make up our bones.
Bones are hidden under the skin.
But you can touch them and see their shapes.
Like our own growth, bones grow from a very young age.
As the bones grow, so do we.
The smallest bone is in our ears,
And the biggest bone is on our thighs.
Some bones act as protective shields for the body.
The sternum is in the middle of the chest to protect our heart;
There are many ribs to protect our lungs and other vulnerable parts;
The bones of the face are part of the skull;
He protects our brains like a helmet.
Some people think the skull looks terrible.
They like to wear skull masks on Halloween.
A long time ago, pirates used skull flags with skulls and crossed bones to scare people;
Today, a skull and Crossbones represent danger or poison.
In this passage, I translated you into us, mainly because of the differences between Chinese and English. Chinese likes to use the first person;
English likes to use the second person.
