What does it mean to be green? "Green" is more than just a color. It also means taking special steps to protect the environment. Why green? Plants are green, and without them the Earth wouldn't be such a lovely home for us human beings. What can we do?

Reduce It!

For instance, a shorter shower means you used less water and less fuel since your house uses to run the heater that warmed up the water.

Reuse It!

Sometimes people call ours a "throwaway society". It means that we're a little too willing to throw away old stuff (东西) and buy new stuff. For instance, if your baby brother becomes older and loses interest in his plastic basketball hoop (篮圈), why not give it to another family who has a little kid?

Recycle It!

Recycling has never been easier. Many communities will pick it up right in front of your house and some towns even require it. Recycled goods go to a recycling center, where they can be turned into new cans, bottles, and paper.

Enjoy It!

It's true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that's ready for you to explore. Go for a hike, visit local nature centers and gardens, and climb up mountains.

But before you travel the globe, take a look at your own backyard. Is there a spot where you could plant a tree or put in a little fruit or vegetable garden?

A. Get out there and get your hands dirty.

B. Here's a four-step guide to being green.

C. Turn off the water when you're brushing your teeth.

D. When you use less of something, you do a good thing for the Earth.

E. You can start locally by visiting the naturally beautiful spots in your city.

F. You can watch with pride as your tree takes root and your garden plants grow.

G. Many times, even if you no longer need something, someone else just might.

Understanding why the giant panda has such noticeable color has been a long-term problem to solve. To find out the answer, Caro and his colleagues looked at photos of pandas and 195 other carnivore (食肉动物) species, including 39 subspecies of bears. Then, they recorded the coloring on each area of those animals' bodies, and compared them with areas of the panda's body. "Compared with the previous studies, the breakthrough in this study was treating each part of the body as an independent area," Caro said.

The research team tried to figure out the purpose of the dark-colored furry areas. After going through many comparisons, the researchers determined that the white parts of the giant panda help it hide in the snow. In contrast, its black arms and legs help it hide in the shadows, they said. The panda's white-and-black coloring didn't appear to be related to temperature regulation. Nor did they find evidence that the dark circles around a panda's eyes helped to make them look cuter.

"This really was a great effort by our team, finding and scoring thousands of images and scoring more than 10 areas per picture from over 20 possible colors," study co-author Ted Stankowich, an assistant professor of biology at California State University, Long Beach, said in the statement. "Sometimes it takes hundreds of hours of hard work to answer the simplest question: Why is the panda black and white?"

Since its launch, Deepseek has been used in education, healthcare, and environmental protection. In schools, it helps teachers design courses based on students' learning habits. In hospitals, it assists doctors in predicting diseases by studying medical data. More importantly, Deepseek's energy-saving design reduces computing power consumption by 50%, making AI technology greener.

However, some experts warn that over-reliance (过度依赖) on AI might weaken human creativity. Prof. Li from Peking University says, "We should use AI as a tool, not a replacement for human thinking." Deepseek's team also agrees, emphasizing their goal is to "empower humans, not control them."

Looking ahead, experts believe AI like Deepseek will reshape careers. Routine jobs like data entry may decline, but new roles in AI management and human-AI interaction design are emerging. As the system's lead engineer Dr. Wang noted: "The real challenge isn't building smarter machines, but teaching people to grow alongside them. In the future, humans will surely coexist harmoniously with artificial intelligence."

At about 7:00 PM that evening, I got a knock on the door. A man asked if I was missing a cat. It turns out the man found Max after he'd been hit by a truck. He saw my cat lying in the road on the way to work, and stopped to see if he could do anything. He was an electrician (电工) with a full day of house visits, so he drove around with my cat in his car all day as he went through his work day. He kept Max warm, gave him water, and even split (撕) his ham sandwich with him.

I asked how he could possibly know it was my cat, for my cat is a master at getting out of his collar, so he didn't have his tags when the man found him.

Turns out, after his shift (轮班), he went door to door down the entire road where he found Max, asking if anyone was missing a cat. He said he loved cats, and would want someone to do the same for him. He went back to his car, got my cat, and asked if it would be okay with him saying a few kind words for us. I don't usually do this kind of practice, but I told him it was fine. He took a moment to wish my cat a quick recovery and a long life, then got back in his truck and drove away.

The whole interaction lasted maybe 5 minutes, and I never even got his name. My cat made a full recovery, and is sleeping next to me as I write this, 8 years later. It's the nicest thing anyone has ever done for me, and it came at a time when I was feeling pretty down about humans.

I wish I knew who he was and I could thank him properly. I'll never forget it.
