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?

根据短文理解,选择正确答案。

    Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood-powered or coal-powered stoves.

    One way to reduce the number of deaths is through cooking equipment powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the "Sol-4". "It is four square meters of mirrors, six to eight meters in length. It is quite a large cooker. "

    The "Sol-4" works by reflecting (反射) light from the sun off large mirrors. The mirrors direct (把……对准) the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.

    The cooker is also much "friendlier" than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals would be less likely to have breathing illnesses from harmful smoke.

    At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.

    Each cooker costs about $ 2,000, which is a large amount of money for most Africans. To solve that problem, Crosby Menzies has created a non-governmental organization called Solar Cookers for Africa.  It plans to raise money through donations to provide poor people with solar cooking equipment.

Birdwatching is becoming more and more popular in many parts of the world.

Birdwatchers enjoy looking for and listening to different kinds of birds. To watch birds, all you need is a pair of binoculars, a field guide and your love for birds.

If you are just starting birdwatching, buy a pair of cheaper binoculars. A field guide helps you learn about the birds' appearances, calls and habits before birdwatching.

When you are ready, it's best to go to the wild with someone who is more experienced. You can join a birdwatching group to learn about some beginning skills.

Start birdwatching in the morning, when birds are searching for food. Most of the time, you will hear birds' calls from all around you, but you will not see any birds easily. Look for the movement in trees, and bring your binoculars to your eyes. The most important work for a birdwatcher is to identify(识别) the birds he/she sees. A bird's shape, size, colour and habits can help a birdwatcher identify it. When you identify a bird, don't forget to take notes about it on your notebook.

To find more and different birds, you may wish to plan trips to birds' different living areas: forests, lakes, rivers, wetlands, etc.

When watching the birds, you should always keep in mind: resp ect wildlife and protect their living areas.
