A In the sea there are many islands
In its warm water there are some little ones
We call them "Coral islands"
A coral island is very nice to look at
It looks like a ring of land with trees, grass and flowers on it
One part of the ring is open to the water
There is a little round lake inside the island
If you look into this lake, you will see beautiful coral
You may think they are flowers
If you look at a piece of coral, you will see many little holes in it
In each of these holes a very small sea animal has lived
These sea animals make the coral
They began to build under the water
Year after year, the coral grew higher and higher
At last it grew out of the water
Then the sea brought it into small trees and something else
After some years, these things changed into earth
