1 . Our Future in Space

Many people believe that one day, we may leave the Earth to make our home among the stars. At that time, many people, including you, might live in a space station 200 miles above the Earth.

Space Cities

There will be cities like the one we are living in now.     1     Hundreds, or even thousands, of people will live, work and go to school there.

In fact, we have explored(探索) part of the Moon, and even sent spaceships to the surface of Venus and Mars.     2    

Go into Space

The Moon is full of valuable metals. These metals—if we got them—could be used to build factories and space stations.     3     In that case, more energy can be turned into electricity—for creating comfortable living conditions.

From space, too, we can look down on the Earth and study the atmosphere, its weather, and the influence of air pollution to save it.

At Home in Space

    4     For example, we have to protect ourselves from the ultraviolet(紫外线) because it can give us bad sunburns. Besides, our bones(骨头) will become weaker if we stay out in space for a long time. But we’ll surely find out the solution.

Yet, these risks won’t keep people from going into space.     5     And people will live there with many different interests—medicine, farming, teaching and so on.

The next hundred years will be filled with other worldly adventures, exciting scientific discoveries, and danger, as humans leave the Earth—perhaps forever.

A．But outer space can be a dangerous place.

B．It seems impossible to live in the outer space.

C．Finally, Earth-like environment will be built in space.

D．Without doubt, the research of space has already begun.

E．Also, in space, there is no air to prevent the sun’s energy.

F．Space schools, hospitals, factories and farms will be built.

3 . In 2080, the Earth is dying, and moving to Mars seems to be the only way out for mankind. A team of American astronauts begin to search on Mars. This is what the movie Red Planet begins with. Known as Red Planet Mars is popular with science fiction(小说) writers and filmmakers.

Mars is the fourth planet from the Sun. We can see the surface of Mars from the Earth. It is half the size of our planet. The rocks, soil and sky have a red or pink hue(色调). The red color was observed by star-gazers throughout history. The ancient Romans named the planet “Mars” after their god of war because of its red color. The ancient Egyptians named it “Her Descher” meaning the red one.

The surface of Mars is more like the Earth than any other planet. However, because it is farther from the Sun than the Earth, temperatures on Mars are much lower. Most of the time the temperatures are far below freezing. The average temperature on Mars is -63℃ with a highest temperature of 20℃ and a lowest of -140℃. Plants and animals could not live now on Mars.

However, many scientists believe that such life may have existed long ago. On 6th August, 1996, scientists discovered a piece of rock from Mars. It fell to the Earth 13,000 years ago, and evidence of simple fossil creatures has been found in it. However, some scientists still don’t accept that there was life on Mars. People may not be so sure about life on Mars until a sample(样本)of life is brought back

6 . We look at the sun every day.     1    

On September 2nd, 2021, China’s Fengyun-3E satellite took its first photos of the sun.     2     The pictures taken are very clear. The satellite was sent into space on July 5^th. And by the end of 2021, China released an album of photos taken by the satellite.

One of the satellite’s sides faces the sun all the time.     3     Why is watching the sun so important?

Clear pictures of the sun can help scientists study it more deeply. For example, scientists can better study solar storms (风暴). These may affect (影响) weather on Earth.     4     An astronaut would be in great danger if he or she was on the moon during the storm.     5

9 . From far out in space, Earth looks like a blue ball. Since water covers three-fourths of the Earth’s surface, blue is the color we see most. The continents（陆地）look brown, like small islands floating in the huge, blue sea. White clouds cover around the Earth like a light blanket（毯子）. The Earth is shaped like a sphere, or a ball. It is 25, 000 miles around! It would take more than a year to walk around the whole planet. A spaceship can fly around the widest part of the sphere in only 90 minutes.

Even though spaceships have traveled to the Moon, people cannot visit the Moon without special suits. The Moon has no air or water. Plants and animals can’t live there either. Astronauts first landed on the Moon in 1969. After that, there were six more trips to the Moon. They brought back Moon rocks, which scientists are still studying. There are holes, or craters（火山口）, all over the Moon’ s surface. Scientists believe that meteorites（陨石）smashed into the Moon millions of years ago and formed the craters.

The Sun is the closest star to Earth. A star is a hot ball of burning gas. The Sun looks very big because it is so close. But the Sun is just a medium-sized star. Billions of far-away stars are much bigger than our Sun. The burning gases from the Sun are so hot that they warm the Earth from 93 million miles away! Even though the Sun is always shining, the night here on Earth is dark. That's because the Earth rotates, or turns around, every 24 hours. During the day, the Earth faces the Sun. Then we see light. During the night, the Earth turns away from the Sun. Then it faces the darkness of space.

Each day we learn more about the Earth, the Moon and the Sun.

1. When we look at the Earth from outer space, the color we see most is blue because ________.

A．most of the Earth is covered in land	B．the Sun’s rays make the Earth look blue

5. The main idea of the passage is ________.

A．plants and animals can’t live on the Moon

B．without the Sun we would have no heat or light

C．we know a lot about the Earth, Moon, and Sun, but there is still more to learn

D．from outer space, the Earth looks tiny, even though it is thousands of miles around
