1 . In the sea there are many islands. In its warm waters 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 tress, 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. Do they not teach us a lesson? Can you think what the lesson is?

3 . Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air,water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you， you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed， some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。 Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places， they usually grow into new plants.

4 . Tom goes everywhere with Catherine Green, a 54-year-old secretary. He moves around her office at work and goes shopping with her. "Most people don't seem to mind Tom," says Catherine, who thinks he is wonderful. "He's my fourth child," she says. She may think of him and treat him that way as her son, buying his food, paying his health bills and his taxes, but in fact Tom is a dog.

Catherine and Tom live in Sweden, a country where everyone is expected to lead an orderly life according to rules laid down by the government, which also provides a high level of care for its people. This level of care costs money.

People in Sweden pay taxes on everything, so aren't surprised to find that owning a dog means yet more taxes. Some people are paying as much as 500 Swedish kronor in taxes a year for the right to keep their dog, money that is spent by the government on dog hospitals and sometimes medical treatment for a dog that falls ill. However, most such treatment is expensive, so owners often decide to offer health and even life premium for their dog.

In Sweden dog owners must pay for any damage their dog does. A Swedish Kennel Club official explains what this means: if your dog runs out on the road and gets hit by a passing car you, as the owner, have to pay for any damage done to the car, even if your dog has been killed in the accident.
