Have you ever hoped a toy balloon? They are very light. But there are much bigger balloons can fly very high up in the sky. They are big enough to carry people. They are called hot-air balloons.

To make a hot-air balloon go up, turn on the burner(燃烧器). That will make the air inside the balloon hotter. Then the balloon will go up.

To make the balloon go down, turn off the burner. The air inside the balloon will get cooler. Then the balloon will go down. Underneath(在….下面) the balloon there is a large basket. That is where the pilot and the passengers go.

The burner is just above the basket. You can stand in the basket and turn the burner on and off. The balloon will go where the wind is blowing the right way! Do you want the balloon to go somewhere special? First make sure the wind is blowing the right way!

People have been flying in hot-air balloons for over two hundred years. Before planes it was the only way of flying. Today people fly in hot-air balloon for fun. Some people like to race hot-air balloons.

As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.
Let’s think about how this works. As wave energy passes through the water, the energy makes particles （粒子） of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.
　  So why can you see a wave knock you down on the shore？When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.

Most animals are helped by people. They can’t live without us. But sometimes people have made the environment worse. For example, in some parts of the world the forests are being cut down.

The animals in the forests have become fewer and fewer. People hope to grow more food on the land, but the wind blows the earth away. Now forests become smaller and smaller, the soil becomes poorer and poorer. Now there are fewer animals and plants in the world. Insects (昆虫) are usually killed, but some plants need insects. Their seeds (种子) can’t spread without them. Birds eat insects, and without insects many kinds of birds will die.

There are hundreds and hundreds of plants and animals, and each plant is helped by another, so does each animal. If you hurt one, you will hurt another, then another. Scientists know this well. They don’t want people to break their environment.

1.It isn’t good for our environment to cut down forests.

2.Animals in the world are becoming fewer and fewer.

3.Animals and plants helped by each other.

4.After the wind blows, the earth becomes richer and richer.

5.This article tells us it is important to make our environment worse and worse.
