Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.
According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (交通工具).
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.
"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.
"The time to act is now. The longer we leave the problem, the bigger it will become," he says.

There's much to see under the sea, but you need to remember that light behaves differently in water than in air. The objects appear closer to you than they exactly are. You might find yourself reaching out to touch something and completely missing it.
Objects under water will appear larger than they would on the surface, too. Be careful not to tell any stories about the big fish that got away. That fish might not be so big after all! It's just because sometimes things can seem to be as much as about 33 percent bigger in water!
What's more, in deeper water, colors just don't seem as bright. In fact, it looks as if some colors are missing. Remember the color of an object results from the wavelengths (波长) of light that are reflected (反射) from its surface. And light is taken in as it moves down through the water.
Swimmers wear wet suits to keep warm underwater. Let's take a bright red, yellow, and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in the water. The red part now looks almost black because the red light wavelengths, the longest among these three colors, are missing. As you go down deeper, the same thing will happen to the yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater, you will look terrible, like a ghost! And you have to wait for your return to the surface to enjoy the bright colors again!
1.You miss the object underwater when you want to touch it because________.
A.your eyesight is quite poor
B.you are not quick enough
C.it is not as close as it seems
D.it disappears very quickly
2.The example of the wet suit is used to explain the change of________of an object underwater.
A.the color B.the size C.the position D.the weight
3.The underlined word "descend" probably means________ in this passage.
A.go out B.go up C.go in D.go down
4.Which of the following is true?
A.The wavelengths of red light are longer than those of blue light.
B.A four-meter-long fish looks three meters long underwater.
C.Much water will be taken in by the swimmer deep in the water.
D.You will see a ghost if you go as deep as 6 to 9 meters into the sea.
5.The best title of this passage is________.
A.The Standard of Color Underwater B.The Direction of Light Underwater
C.The Brightness of Color Underwater D.The Behavior of Light Underwater
What is the future of AI (人工智能)? Will it be a good thing? We asked four students what they think.
I think AI will be more useful in our future lives. It's now used in many fields, like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I'm sure AI will help us solve many problems. —Tina | I am worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced (取代) because AI robots will do lots of human jobs. —Bill |
I really think that AI will change the way we work, the way we live, and the way we think. Imagine if we could put a CPU (中央处理器) into our brains! Soon we'll be able to improve our math and memory. How exciting! —Mary | Think of what's happening right now: Some robots are used to kill animals under human orders. So I think AI will be very dangerous for humans. We need to be careful about what we ask machines to do. —John |
1.John thinks that AI will be________.
A.exciting B.surprising C.helpful D.dangerous
2.Who thinks AI will help us solve many problems?
A.John. B.Bill. C.Tina. D.Mary.
3.Bill thinks humans may be replaced because________.
A.we can't improve our memory B.AI robots will do human jobs
C.we can put a CPU in our brains D.AI can help to improve our math
I'd planned to spend my weekend in the sun, planting flowers outdoors. But that was before the pair of crows (乌鸦). Out of nowhere, they had set up their base camp in our garden.
We first discovered the crows on Friday morning. It was early, and the sound the birds made traveled through our neighborhood. I thought they'd go away soon. But, no. They were getting louder and probably made my neighbors angry nearly as much as us with the noise. I felt a little disappointed.
Then, on Sunday afternoon, I looked out of the kitchen window to see our dog Quatchi watching something on the ground. I found a small coal-black bird in the grass. Its eyes were milky, and it stayed perfectly still as my dog inched towards it. Only when Quatchi touched his nose to its head did it walk away. I grabbed the dog and locked him inside and came back with my camera.
I never thought that the young would be hanging out on the ground, growing and gaining strength as its parents guarded it from above. The second I saw this little bird I forgave (原谅) the crows.
To be honest, I've never been much of a bird person. I also have a healthy respect for birds.
They're basically living dinosaurs (恐龙).
I wish they'd chosen another garden. There are only so many sunny days in Seattle, and I still can't do any gardening out there. But I'm also thankful that I got to see this little bit of nature. It's pretty amazing.
The experience has also strengthened my wish to create a beautiful garden that attracts lots of bees, butterflies, and yes, birds. They are welcome here.

3.The writer changed her thoughts to the crows when________.
A.she planted flowers in her garden B.she locked her dog inside
