Hi! My name is John. I’m eleven years old. I’m in Grade Seven. Our classes start at 8:00 in the morning and finish at 3:30 in the afternoon. My favorite subject is science, because I can learn a lot from it. I don’t like geography. I think it’s boring. I’m very busy every day. Here is my schedule (课程表). Please have a look.

The Earth is a beautiful place. There are forests and rivers, mountains and fields. Some places are very hot, and some are very cold.

There are many different plants. Some are large. Some are small. All plants need light and water. There are different animals on Earth too. Some live on the land. Some fly in the sky. Some live under the water.

There are also many people like you and me on Earth. The Earth provides us with air, water and food. It is our home.

Today, there is a lot of pollution. We burn things to make energy. This pollutes the air. We put our rubbish into the sea and under the ground. This pollutes the Earth and kills animals and plants.

We must stop doing these things. It is important for us to protect the Earth for our future.

Many people believe that the Moon was once part of the Earth and broke away millions of years ago. Other people say that it came from another part of space.

There are high mountains, deep valleys and wide flat spaces on the Moon. Animals and plants can’t live on the Moon because it has no air or water. There are no clouds, no rain and no snow, either.

Sound needs air to travel. There is no air on the Moon. So there can be no sound there. The Moon is a silent place.

The Moon has no light of its own. It looks bright because the Sun’s light shines on it. During the day, the rocks become hotter than boiling (沸腾的) water. This is because the Moon is closer to the Sun than the Earth.

The Moon is about 383 thousand kilometres away from the Earth. It takes a spaceship about three days to reach the Moon. But it would take a car nearly six months to travel this way.
