The moon 【小题1】 around the earth. It is quite near to us in 【小题2】. It is only 380,000 kilometres away and man has 【小题3】 visited it. So far, no man has travelled 【小题4】 than the moon, but spaceships without people have 【小题5】 other planets of the universe.

Many countries have 【小题6】 up satellites(卫星) into space.

These satellites go 【小题7】 the earth and help us to learn more about the earth, the weather and other things. Many countries use these satellites to send and receive 【小题8】. For example, 【小题9】 their help, China can send its TV and radio programmes to other countries. We can also use satellites to 【小题10】 us make telephone calls to foreign countries.

I’m so happy! Tomorrow I’ll be one of the first students to 【小题1】. The spaceship will leave the Earth at 9 a.m.. It’ll take us to the Moon. I can’t wait!

The moon is around 380,000 kilometres from the Earth, so it’ll take us 【小题2】 to get there. There’s no gravity in space, so we’ll all be able to float around in the spaceship. We’ll have to tie ourselves to our beds so that we won’t float away in our sleep! 【小题3】, our bodies may get weak, so we’ll have to 【小题4】 every day.

When we arrive, I’m going to walk on the Moon. I’ll have to 【小题5】 to help me breathe because there is no air on the Moon. I am going to take as many photos as I can, that is, if my camera still works up there.

The earth is a planet and it 【小题1】 around the sun. Seven other planets also go around the sun.【小题2】of them has an environment like 【小题3】 of the earth, so scientists do not think they will find life on them. The sun and its planets are 【小题4】 the solar system, and our solar system is a small part of a 【小题5】larger group of stars and planets, called the Galaxy or the Milky Way. There are 【小题6】of stars in the Galaxy, and our sun is only one of them.

Scientists have also 【小题7】many other galaxies in the universe. They are very far and their light has to travel for many years to 【小题8】 us. So how 【小题9】 is the universe? It is 【小题10】to imagine.
