A
Scientists have always wanted to know more about the universe.
Years ago they knew many things about the moon. They knew how big it was and how far away it was 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 kilometres away from the Earth. A plane cannot fly to the moon, because the air reaches only 240 kilometres away from the Earth. But something can fly even when there is no air. That is the rocket.
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 the space. Rockets with men in them have been to the moon. Several satellites without men in them have flown to another planet much farther away than the moon. One day rockets may be able to go to any place in space.
B
In the universe, as we know, there is the Sun, the moon, the Earth and a good many stars. Through our geography lessons, we know the Earth goes round the Sun, and the moon goes round the Earth. We have day and night because the Earth keeps turning all the time. When our part of the Earth turns to the Sun, it is day. When our part of the Earth turns away from the Sun, it is night.
Just because the moon is closer to the Earth than the Sun, it looks much bigger than the Sun. Big things will look smaller when they are farther, and small things also look bigger when they are nearer.
The Sun is bright enough to give out very strong light. The moon can't give any light at all, but it looks quite bright, too. Why? In fact, the light from the moon comes from the Sun. The moon looks much bigger and brighter than the stars. But actually (事实上) the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are farther away from the Earth.
There are still many other planets in the universe. But of all these planets, only on Earth there are living things and people can only live on Earth, too. But at 9∶00 am on October 15th 2003,Chinese astronaut Yang Liwei was set up to space. He stayed there for 21 hours. It was the first time for Chinese to get into space.
The moon landing
It's always been man's dream to fly like a bird in the sky. Back in 1865,a French writer once wrote about man's landing on the moon on a special airplane with three people inside, and the first person to touch the ground on the moon would be American. That was considered (被认为) to be a crazy (疯狂的) idea at that time. Over one hundred years later, on July 20,1969,however,this impossible dream did come true.
It was a big day in the history of the 20th century. On that day, a special airplane took three brave (勇敢的) men from Cape Kennedy at a speed of 35,533 feet per second. The trip to the moon took 103 hours and 30 minutes. In fact, it was the first time that man ever ”walked” in outer space. On the trip, two of the spacemen spent two hours on the moon walking like flying, and the other stayed in the spaceship. They studied the appearance of the moon. Four days later, the spaceship Apollo 11,returned to the earth and the astronauts were welcomed by people around the country. The man who took the first step, Neil Armstrong, said, “That's a small step for a man, one giant leap for mankind.”This has been said again and again in every language around the world since then.
