If we wake up one morning and see so many of you people wandering around in spacesuits, we're going to be really upset. We don't want to be impolite. It's just that we're shocked by what you've got going on down there. Earth looks like a mess. You've got health problems, environmental pollution, traffic jams, political fights, etc. No wonder so many of you want to leave Earth for another planet. We know you'd like it here. That's what frightens us. you'd all move to Venus at once. If we start having you all up here, pretty soon, the Martians(火星人)and Jupiterians(木星人) are going to come, too. But we can't handle so much. Venus is not Earth 2. We suggest _______________________ because _____________________. God bless you! Sincerely, Venusians(金星人)

At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars. Our own planet, Earth, is becoming more and more crowded and polluted. Luckily, we can start again and build a better world on Mars.

First of all, transport should be much better. At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months. However, by 2100, spaceship 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 produce the food and air that we need. However, can these plants produce water for us? There is no answer now.

There is a problem for us to live on Mars. Mars suck us much less than the Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.

Life on Mars will be better than that on Earth in many ways. People will have more space. Living in a large building with only 10 bedrooms is highly possible. Many people believe that robots will do most of our work, so we have more time for our hobbies.

There will probably be no school on Mars. Every student will have a computer at home which is connected to the Internet. They can study, do their homework and take exams in online schools. Each student will also have his own online teacher called “e-teacher”.

However, in some ways, life on Mars may not be better than that on the Earth today. Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today. Also, space travel will make many people feel ill. The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.

The sun is one of the stars . Some planets are balls of rock and some are balls of gas. We live on the planet Earth. The earth spins(自转）around once every day to give us day and light.( 72 ) The earth goes around once every year to give us different seasons. There are eight planets ________ (move)（73) around the sun. We call the family of the sun and its planets the solar system. Mercury( 水星 ) is the nearest to the sun, so it is very hot. It is the smallest planet. Venus(金星)is very bright and hot. It is the nearest to the earth. Mars is covered with orange-red dust and rocks, so it looks like a red star in the sky. It has seasons like the earth. Jupiter(木星) has more than 16 moons( 卫星 ) and it is the biggest and heaviest planet. Saturn(土星)has more than(74) 22 moons. The other planets such as Uranus(天王星) and Neptune( 海王星), are all very far from the sun and very cold. We need a telescope(   望远镜 ) to see them.

9 . Our reporter asked people what they were doing on July 20th, 1969 when man first walked on the moon. Here is what they said:

Kate Jones, waitress I remember that day very well. I was fifteen years old. It was a hot and humid day, and I was with my family in the mountains. We were having a picnic. We didn’t see the moon landing when it happened, but we were thinking about it. We saw it later on the TV news.

John Bates, postman I was eighteen years old. It was a very exciting day. I was watching TV at home when the astronaut walked on the moon. His name was Neil Armstrong. I remember he could jump really high because people aren’t so heavy on the moon. When he returned, he became a national hero in America, and famous all over the world.

Paul Robinson, doctor I was twelve. I remember the day, but I don’t remember what I was doing. I remember I wanted to go to the moon, too. My dream was to become an astronaut and fly in a rocket. I wanted to see the earth from the moon. The astronauts on the moon said that the earth looked very beautiful from there.

Linda Brown, clerk I was working that day. I was twenty then. I didn’t see the man land on the moon because I was busy. Of course I knew about it. I read about it in the newspaper the next day. I thought it was amazing. Maybe one day people will travel to the moon for vacations!

Mark Green, teacher I was only seven years old then. My parents talked about it, and I learned about it later in school, but I don’t remember the day. I was too young to remember. Maybe I was having fun in the playground with my friends when it happened.

10 . Unless we spend money to spot(认出，发现) and prevent asteroids(小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.
Asteroids are bigger versions of the meteoroids(流星体) that race across the night sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth.
But $500 million worth of new telescopes right now, then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’ll have a way to change its course.
Is it worth it? Two things experts consider when judging any risk are (i) How likely the event is; (2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare but if one did fall. It would be the end of the world. “If we don’t take care of these bid asteroids, they’ll take care of us,” says one scientist. “it’s that simple.”
The cure, though, might be worse than the disease. Do we really want fleets(舰队，车队) of nuclear weapons sitting around on Earth? “the world has less fear from doomsday(毁灭性) rocks than from a great nuclear fleet set against them.” Said a New York Times article.
1. What does the passage say about asteroids and meteoroids?

A．It is very unlikely but the danger exists.

C．Collisions of smaller asteroids with Earth occur more often than expected.

D．It’s still too early to say whether such a collision might occur.

3. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?

A．It sounds practical but it may not solve the problem.

B．It may create more problems than it might solve.

C．It is a waste of money because a collision of asteroids with Earth is very unlikely.

D．Further research should be done before it is proved applicable.

4. We can conclude from the passage that __

A．While pushing asteroids off course nuclear weapons would destroy the world.

B．Asteroids racing across the night sky are likely to hit Earth in the near future.

C．The worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime.

D．Workable solutions still have to be found to prevent a collision of asteroids with Earth.
