Say Cheese!
We all want to look our best in pictures, and our 1 are a big part of that. But when we try to say "cheese", the resulting smile is often not as natural as our real happy face. So, why can't we smile 2 in photographs?
In 1862, French scientist Guillaume Duchenne studied facial expressions and their links to emotions. He described a 3 smile of great joy. This "real" smile is a smiling mouth with smiling eyes. It activates the brain areas that process emotions. A"real"smile 4 crow's feet (鱼尾纹) around the eyes and pulls the cheeks up. This smile is now known as the Duchenne smile.
When we see a smile like this, we recognize it as an expression of true happiness. But a smile made for a photograph is 5 .This is because the brain creates these two types of smiles in different ways.
A"fake"smile doesn't activate the emotional areas of the 6 Instead, it activates a motor neural pathway(运动神经路径).In other words, only your muscles respond to this kind of smile. Your brain knows that a smile should make your mouth 7 , so it activates those muscles. But when you make this type of"fake" smile, you aren't using all of the muscles involved in a natural smile.
The Duchenne smile is widely considered the true smile of happiness. However, some people can mimic(模仿)it, either in a photo or in real life. You've probably seen people do this. Actors, for example, spend a lot of time 8 their perfect smile for the camera.
In a study, researchers asked people to 9 in front of a camera. Over 70 percent of them could successfully mimic a Duchenne smile. For most of us, this is good news. With a little practice, we could all look 10 in our photographs, even if we're feeling blue.

②The sunlit Censer Peak exhales incense-like cloud,
③ As if the Silver River fell from azure sky.
④ The cataract hangs like upended stream, sounding loud.

Sunny October 13 There's a new girl named Sasha in our class.Mrs.Ramirez put Sasha at our table, right next to me. Then Mrs. Ramirez said, "Becky, I know you'll be a big help to Sasha."I smiled at Sasha, and she smiled back. Maybe we'll become friends. It would be so great to have a new friend! |
Cloudy October 17 I am really upset with Sasha. I'm not sure if I want to be her friend. I've been trying hard to be nice, but today she got me in big trouble! When the break ended this afternoon, Mrs. Ramirez asked me to bring the kickball inside and put it away. When I walked into the classroom, I broke a rule-I kicked the ball indoors. The ball knocked over a flower pot. Since Mrs. Ramirez was still out in the hall, all I had to do was to pick up the pot pieces and clean up the floor. But before I could,Sasha ran and got Mrs.Ramirez. How terrible! Now I have to stay inside! I am so mad at Sasha! |
Sunny October 21 Today our class went to the computer lab. When the lesson was over, Mr. Munn reminded us to turn off the computers and printers. Then we lined up and waited to be dismissed.That was when I noticed that the computer and printer that Sasha had used were still on. I thought about telling Mr. Munn. But instead, I walked out of line quietly and turned off the machines. When I got back in line, Sasha was smiling at me. She made a silent "thanks"with her mouth. |
Fu was born into an embroidery family inYangzhou. His mother is a master craftswoman of Suzhou embroidery. Under the influence of his parents, Fu first fell in love with the art of embroidery at the age of four. In his senior year of high school, Fu was clear about his life goal: to promote the traditional art of embroidery.
After graduating from college, Fu founded a research center of Suzhou embroidery together with his mother. Since then, he has invented many new stitches and has trained many embroidery workers.
The embroidery artist often works overtime to finish his works. But, even so, he continues to find pleasure in his work. "I am doing what I love, so I never feel tired," the 35-year-old says.
Most recently, the artist created a piece of "bronze ware(青铜器)"on a piece of cloth using his needle and thread. "I thought of doing this because many bronzes can only be seen in museums. Yeta work of embroidery can be hung in one's home or office. People can see it at any time,"Fu explained.
Fu Jian also realized that studying techniques is not enough. In order to better protect this culture, he also promotes embroidery culture on new media platforms in his spare time. "I hope more people can understand the traditional craft of embroidery and join in. Only with extensive participation can this traditional culture form a flourishing scenario(繁荣的局面)." Fu toldChinanews.
A group of Chinese scientists have invented a small type of robotic fish to clean up microplastics in the ocean. The robot's "secret weapon" is a layer (层)of mother-of-pearl. This material comes from clam(蛤蜊)shells. The robots are designed to absorb(吸收) microplastics while moving through the water.
These fish-shaped robots are only 1.5 cm long. They can travel fast underwater. They are made of a soft chemical compound. As they swim along, they pick up microplastics nearby. The tiny pieces then stick to them.
According to the researchers, the robots can take in different kinds of microplastics and even repair themselves when damaged. And if a robot fish is accidentally eaten by a real fish, it could safely digest the material, the team added.
The robots work well, but the scientists still want to improve them. The ideal versions will dive even deeper and remove larger amounts of microplastic waste from deep ocean areas. Besides that, they even say that similar robots could be developed to be placed inside the human body to remove unwanted materials or disease.
