In the universe, as we all know, there is the sun, the moon, the earth and a good many stars. Through our geography lessons, we know the earth goes around the sun, and the moon goes around 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 further, and small things also look bigger when they are nearer.
The sun is big 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 further away from the earth.
There are many other planets in the universe. But of all the planets, only on the earth there are living things and people can only live on the earth, too. But at 9:00 a.m. on October 15th,2003, Chinese pilot Yang Liwei was sent up to space. He stayed there for 21 hours. It was the first time for Chinese to get into space.

Venus is close to the earth. It is the second planet from the sun. The earth is the third planet from the sun. Venus is similar (相似的) to the earth in size and mass (质量). It is often described as the earth’s “sister”.
Scientists have been learning about Venus for a long time. First they looked at Venus through telescopes (望远镜). But Venus is covered with thick clouds. Scientists could not see Venus well through the clouds. So they made guesses about it.
For a long time, scientists thought that Venus had water and plants. They thought Venus might have animals too. But they didn’t know for sure.
Then scientists found a way to learn more about Venus. In the 1960s, they began sending probes (航天探测器) to Venus. The probes flew through the thick clouds. They took pictures of Venus up close. They found out many things too. The probes sent the pictures and things they found out back to the scientists.
The scientists learned a lot from the probes. First they learned that most of their guesses were not right. And they learned that Venus is very hot.
After that, scientists knew they could not send people to Venus. But they still wanted to know more about it. So they sent new probes. These new probes took great pictures of the planet. The pictures showed that Venus has plains (平原) and mountains! And in some ways, Venus looks like the earth.

Our planet(星球), the Earth, is becoming more and more crowed and the environment is badly polluted. Some people think that we will have no places to live in the future. Don’t be panic(惊慌的). Recently some scientists believe that we will live on Mars(火星) by the year 2100. Here is what life will be like on Mars in 2100.
Tranasport(交通) will be much better. It takes months to get to Mars today. But in 2100, the spaceship can travel at half the speed(速度) of light. It might take us two or three days to get to Mars.
Because none of us can live without food, water or air, scientists will develop plants that can be grown on Mars. These plants will produce(生产) food and air that we need. However, can these plants produce water for us? There is still no answer now.
Life on Mars will be better than that on Earth in many ways. Living in a large building with 10 bedrooms in even possible for people. Many people believe that robots will do most of our work, so we will have more spare(空闲的) time.
There will probably be no schools on Mars. Every student will have a computer to study at home. Every student will also have their own online teacher called “e-teacher”. It’s really interesting, isn’t it?
1.Our planet .
A、has more and more robots
B、has more and more animals
C、isn’t clean as before
2.How long might it take us to get to Mars by spaceship in 2100?
A、Two or three days.
B、Two or three months.
C、Several weeks.
3.There will be plants on Mars that can produce for people according to
the scientists.
A、food and drinks
B、air and drinks
C、food and air

A、food B、schools C、work

First of all, transport should be much better. _______, our spaceships are too slow to carry large numbers of people to Mars - it takes months. However, by 2100, Spaceships can travel at half the speed of light. It might take us two or three days to get to Mars.
Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can be grown on Mars. These plants will _______ the food and the air that we need.
There is still another _______ for us to live on Mars. Mars makes us much lighter than the Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space. To _______ this, humans on Mars have to wear special shoes to make themselves lighter.
Life on mars may be better than that on the Earth in many ways. People will have more space. Living in a large building with 10 bedrooms is highly _______. Many people believe that robots will do most of our work.
