In the sea there are many islands. In its warm waters there are some little ones. We call them coral(珊瑚) 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 to it small trees and something else. After some years, these things changed into earth. Sometimes the wind brought seeds to this earth. Sometimes birds flew over it and brought seeds to the island. The little seeds grew. In a few years there were plants all over the island. In a few more years there were trees growing there.
So you see, these islands were built little by little. The workers were very small. Don’t they teach us a lesson? Can you think what the lesson is?

The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind. The sea is very big. It covers three quarters of the earth. The sea is also very deep in some places. In one place, the sea is about 11 kilometres deep. The highest mountain(山) in the world is about nine kilornetres high. If that mountain was put into the sea at that place, there would still be two kilometres of water above it!
In most parts of the sea,there are plenty of fishes and plants (植物). Some live near the top of the sea.Others live deep down. There are also a lot of small living things,and lots of fish live by eating them. The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But,in 1970,five women scientists lived in the deep sea for fourteen days.

We all know that food makes us grow every day, but sometimes it can make us happy when we feel bad. Food such as sea fish, bananas, pumpkins and chicken can help us be happy. How can they affect (影响)our feelings?
People living by the sea look much happier than other people, because the fresh sea air helps them clear their minds and they eat a lot of sea fish. Bananas have much Vitamin B6. Having more bananas can help us make a quick decision, and become more confident(自信). Eating pumpkins can also help people get into a good feeling because it’s rich in Vitamin B6 and iron(铁).
Are you in a bad mood(情绪)? If you are, don’t sit alone. Go to eat such happy food with your friends. Maybe you’ll feel better.

Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
