We look at the sun every day.     1    

On Sept. 2nd, 2021, China’s Fengyun-3E satellite took its first photo of the sun.     2     The pictures taken are very clear. The satellite was sent into space on July 5th. 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. These may affect the weather on Earth.     4     An astronaut would be in great danger if he or she was on the moon during the storm.     5    

A．It used China’s solar space telescope (望远镜) to do the job.

B．By watching the sun closely, we can take actions to protect ourselves.

C．Big solar storms may also make our phones stop working.

D．But do you know what the sun really looks like?

E．It can watch the sun’s activity without stopping.

2 . Have you ever seen the day begin? The dark sky starts to look brighter. Then suddenly the sky is all pink and red and gold even a little green. The earth has turned bright until the sun is shining on the place where you are. This is what makes it day.

The sun is always shining, but it can only shine on one side of the earth at a time. It can’t light the side that is away from it. When the sun is shining on the other side of the world, it is night where you are. At night, you can see the stars.

All day the stars are in the sky, but the light from the sun is so bright that you can’t see them. When the sun is gone, the stars are bright enough to see. Stars look as tiny as pinheads (针头), but some are even bigger than the sun. Big things look little when they are far away. In the sky, planes look like toys, but on the ground you can see that they are big. Stars are millions of times bigger than planes. They look very small because they are so far away. The sun is closer than the other stars. So it looks bigger.

1. We can’t see the stars in the sky because ________.

A．it’s dark	B．when the sun is gone
C．the light from the sun is not bright	D．the light from the sun is so bright

2. Big things look little ________.

A．when they are far away	B．when they are close to us
C．when the sun is too bright	D．when the sun is gone

3. Why does the sun look bigger than the other stars?

A．Farther than the others.	B．Closer than the others.
C．Bigger than the others.	D．Brighter than the others.

4. When the sun is shining on the other side of the world, ________ where you are.

A．it is bright

B．it is darker

C．it looks brighter

D．it is night

3 . Do you know what will happen in a weightless environment? Students attend a science lesson given by astronauts on board China’s Tiangong space station on Wednesday, March 23, 2022. Zhai Zhigang, Wang Yaping and Ye Guangfu, the members of the Shenzhou XIII, which was launched (发射) on October 16, appear on television screens watched by millions of students across China.

During the 41-minute lesson, the astronauts did four experiments to show physical phenomena (现象) only possible in a weightless environment, such as “liquid crystallization” and “a water bridge”. In one experiment, Wang used a toy of Bing Dwen Dwen, the mascot of the 2022 Beijing Winter Olympic Games, to show how objects fly in Tiangong. They invited the young viewers to do similar experiments to see the differences between space and land environments.

Before closing the lesson, the astronauts answered questions from students. The questions covered the life and work in space, such as how to take care of the skin and whether hot water was available. Wednesday’s event marked the third time Wang had taken part in a space lesson. In June 2013, she gave the nation’s first space lesson to over 60 million Chinese students in Shenzhou X. It made China the second country, following the United States, to have given a lesson to schoolchildren from space.

In early December, Wang gave the country’s second space lesson from the Tiangong station. The astronauts showed viewers how they lived and worked inside the space station.

“These science lessons can encourage students to explore the world of science and technology.” Shi Yi, a physics teacher, said after today’s activity, “Encouraged by China’s spaceflight achievements, my school has built a space science laboratory and the teachers give lessons about space exploration.”

4 . Fun Facts about Our Moon

Have you ever noticed the ways the moon changes? The moon can be bright or dull. Sometimes, we don’t see the moon in the sky at all! Other times, the moon shows up even when the sun is out.

When the moon looks bright, it’s partly because of the sun. The moon has no light of its own. It only reflects the sun’s light. But how?

Think about daytime. The sun makes everything around you bright with light. During daytime, sunlight hits Earth’s surface and makes it bright. During nighttime, the sun is near another part of Earth’s surface, making that part bright, so you see darkness. At night, you also see the moon.

In the same way that sunlight shines on Earth’s surface and makes it bright, sunlight shines on the moon’s surface and makes that bright. Even though you can’t see the sun at night, sunlight reaches the moon’s surface. The sun acts like a giant flashlight in the sky that’s pointed at the moon.

Other things can make the moon look brighter or duller, too. Sometimes, the moon looks brighter because it’s closer to Earth. Fog and clouds in the sky can make the moon look dimmer.

The moon is always in the sky, but we don’t usually see it during daytime. One reason for this is that the sun is so powerful that it makes the sky very bright. The brightness makes the moon hard to see. Imagine turning on a flashlight in a darkroom and aiming it at a wall. You would see the flashlight’s bright light clearly. Now, imagine turning on a flashlight in a room that already has all the lights on. You would hardly see the light from the flashlight because the other lights are more powerful. The moon becomes difficult to see in daytime for the same reason.

The next time you see the big, bright moon in the sky, think of the sun shining its light onto it.

1. The word “reflects” in paragraph 2 probably means _______.

A．sends back

B．picks up

C．carries on

2. What can we learn from the passage?

A．The moon cannot be seen in daytime.

B．The moon shines bright from the sun.

C．You can see the flashlight’s light in a bright room clearly.

3. Which of the following is TRUE?

A．The sunlight can shine on both the Earth’s surface and the moon’s surface.

B．The fog and clouds in the sky can make the moon brighter.

C．The moon becomes difficult to see in daytime because it’s closer to Earth.

4. What is the writer’s main purpose in writing this passage?

A．To state reasons that make the sun look bright or dull.

B．To tell how darkness makes the moon look bright in the sky.

C．To explain reasons that make the moon look different sometimes.

5 . If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).

A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.

If a comet isn’t a star, what is it then?

Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.

Many people perhaps have seen a comet. However no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.

An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again. Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s Comets when it comes near the earth again.

10 . 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.
