Scientists are very interested in the Universe,and they always want to know more about it. Years ago they knew many things about the moon. They knew how big it is and how far away it is from the earth. But they wanted to know more about it. They thought the best way was to send men to the moon. The moon is about 384,000 kilometers away from the earth. A plane cannot fly to the moon because the air reaches only 240 kilometers away from the earth. But something can fly even when there is no air. That is a rocket(火箭)
How does a rocket fly? There is gas(气体) in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky. Rockets can fly out into space. Rockets with men in them have been to the moon. Several rockets without men in them have flown to another planet(行星) much farther away than the moon. One day, rockets may be able to go to any place in space.

There are seabirds as well as land-birds. The most ordinary seabird is the seagull. It has a white body, a white head and a yellow beak. There is a very, very spot of red at the very end of the beak, underneath. All gulls have very strong wings so that they can fly far out to sea. If a gull flies out too far, so that it is too tired to fly back to the shore(岸边), it does not get frightened, for it can sit and rest upon the waves(波浪). A seagulls wings do not get wet because all its feathers have a kind of oil over them, so that when the water gets on to the feathers, it just runs off again. Gulls can even sleep upon the waves.

Sailors(水手) know a lot about seagulls and they never kill them. When the gulls fly a long way out to sea, sailors say that it means fine weather is coming. When the gulls stay near the shore, sailors say they there will be much wind and rain, and perhaps a storm, for the gulls know more about the weather than sailors do.

An astronaut’s work may sound exciting, but living in space isn’t as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them.

When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts’ fingernails(手指甲) and even make them fall off.

In space, you don’t have many choices in what you eat. It’s hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs(碎屑). Crumbs could fly around everywhere.

In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting(喷水) gun and a washcloth.

Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they’re in space to try to keep their bones strong as long as possible.

Perhaps the hardest part of life in space is the feeling of loneliness. Astronauts sometimes have to spend weeks and even months away from Earth. They miss their friends and families.
