The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets its light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light had burned out. Others are still bright, but they are so far away that we cannot see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life giving star.

Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

Today more and more families own computers. Parents buy computers for their children. They hope computers can help them improve their studies in school. Yet, many of the children use computers to play games, to watch videos or to sing karaoke, instead of studying.

Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual (个别的) words, but also understand the importance of word order in a sentence.
Most animals enjoy playing — but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour.
Dolphins live in a very different world from ours, but they are very good at our "IQ tests” . For example, they will jump out of the water when they hear a whistle (口哨) noise. They do this because they will get a fish as a prize.
There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun.
