4 . Our nearest neighbour is the moon. In the sky, the moon and the sun seem to be of the same size because the moon is much nearer.
The moon makes the tides(潮汐)—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world, the difference between “high tide”(when the sea is very near to the land) and “low tide”(when the sea is far away from the land) is very big. This is very important for ships.
The moon is very different from the earth. Gravity on the moon is six times weaker than that on the earth. There isn’t any air. During the day, it is very, very hot but at night it is very, very cold. Nothing can live on the moon.
If the moon goes between the earth and the sun, we have an eclipse(日食) of the sun. The moon stops the light from the sun and we have night in the day.
If the earth goes between the moon and the sun, we have an eclipse of the moon(月食). The moon goes into the shadow(影子) of the earth and it disappears for a few minutes.

5 . People in many parts of North and South America will be able to see a total lunar eclipse (月食) on Sunday night and early Monday morning. The eclipse is special, and it is called a super blood wolf moon by some people.
The moon will be a little closer than it normally is to the Earth. For this reason, it will appear brighter than usual. Such a moon is called a super moon. When the moon is completely eclipsed, it looks darker and appears to have an orange or even a red color. The sunset on the Earth looks orange for a similar reason. Because of its reddish color, an eclipsed moon is sometimes called a blood moon.
In North America, there are traditional names given to each of the 12 full moons that happen throughout the year. January’s full moon is known as the wolf moon or the great spirit moon.
Is there anything I should get ready when I look up the lunar eclipse?
“There are no precautions (预防措施) you need to take when looking at a lunar eclipse, since the moon is never bright enough to hurt your eyes like the sun,” according to Walter Freeman, a physicist at Syracuse University.
It’s just a wonderful thing for the whole family to see because it’s fairly rare to have all these kinds of things together at the same time.

Scientists think that there has been life on Earth for millions of years. However, we haven’t found life on other planets yet. What not?
The Earth is a planet and it goes around the Sun. Seven other planets also go round the Sun. None of them has an environment with air, so people and things cannot grow. The Sun and its planets are called the solar system. The solar system(太阳系)is a small part of our galaxy.
The stars we see at night are the suns in other solar systems. There are more than 200 billion stars in our galaxy, called the Milky Way and our Sun is only one of them.
But scientists have discovered many other galaxies in universe. They are a long way away and their light has travelled for many years to reach us. It is hard to understand how large the universe is.
Scientists have sent lots of spacecraft to look at other planets in our solar system, and some spacecraft have gone beyond the solar system. However, no one has discovered any life in space yet.
But why has no one from other planets sent us a message? Have they tried to send information to us? With so many stars in the universe, are we alone, or is there life out there in space? We don’t know…yet.
