2 Read the text about skeletons and answer questions about what you
have read.
Our skeleton supports our body. It makes a strong frame inside
the body. It gives our body shape and makes it firm.
Our skeleton also protects organs inside the body.
We grow and get bigger because our skeleton grows.
We begin to grow at birth. Our bones get longer and thicker
each year.
When we are about 18 to 20 years old, our bones stop growing.
Sometimes we fall or have accidents and break our bones.
A broken bone is called a fracture. Doctors take special photos
called X-rays to see if a bone is broken or not. The broken ends
of the bone slowly grow back together again.
