The deserts are not as dry as they look. They have groundwater. A new study   says this could help explain the mystery. Lucas Goehring, an expert in physics at Nottingham Trent University in England, led the study. He and his team came up with an explanation for the six-sided shapes.

According to Goehring, below the desert surface is a layer (层) of salty water. You can reach it by digging with your hands. In the hot summer months, the water evaporates (蒸发). This leaves only salt behind. Some of the salt goes into the next layer of water. This layer of water then becomes thicker and saltier than the   one below it. The saltier water goes down and the fresher water goes up.

The process repeats itself to form what scientists call a convection roll (对流圈) which normally has a round shape. There are so many of the convection rolls and they press against each other to form the six-sided shapes.

Scientists say they did their work out of curiosity (好奇心). "Nature presents us with a fascinating mystery," said Jana Lasser, another expert who helped with the study. "It makes us want to solve it."

Could we make a real-life Baymax? There have already been most of the pieces needed to create it. But putting them all together is another story. "There're all kinds of things that need to come together to make something as amazing as Baymax," says Alex Alspach, a robot expert at Toyota Research Institute in the USA.

To build a real-life Baymax, experts need to think about many things. They need the right hardware to make up the robot and the right software to control its movements. They need to plan what the robot looks like and make sure it's safe for humans.

The real-life Baymax needs to be light. If he is too heavy, he might hurt his patients. That is why he should be soft on the outside and full of air inside. But keeping Baymax filled with air would be difficult as he would need to carry a lot of hardware. Heat is also a problem. The motors that make Baymax work will make lots of it. That's dangerous.

The robot's walk is another challenge. He should be able to move around small spaces. "I don't know of anybody who can make a robot move like that right now," says Cindy Bethel, an expert at Mississippi State University.

The real-life Baymax will also need lots of sensors . Scientists are working on sensors that can tell if a person is sick.

Most experts agree that big steps towards making the new robot will come soon. "I think kids will get to see that in their lifetime," Alspach says.

We started by looking at some old paintings in a big room. My mom explained that they were created by famous artists a long time ago. And that's when the trip started to get interesting for me.

Next, we went to a room with real dinosaur bones (骨头). They were huge, and I couldn't believe that animals that big ever existed (存在). We learned how they lived and looked for food. It was cool!

Then, we entered a room with old handcrafts . There were bowls, musical instruments, and even a pyramid (金字塔)! I couldn't believe they were made so long ago—without modern machines. It was amazing to see how people used to live back then.

Lastly, we visited a room with real live insects and animals. There were butterflies flying all around and even a big spider! I got a little scared, but my mom told me they were behind glass and couldn't hurt me.

After we saw everything, we went to the gift shop. I got a cool ruler with dinosaur facts on it and a little toy dinosaur. My sister got a book about space, and my dad got a cool T-shirt.

Going to the museum was fun! I learned so much about history, science, and art. Guess what? I'm taking back everything I said about museums—and I can't wait to go back and see what else is there!

Xavier lives with his grandfather, who is disabled. When it was time for them to go to the ceremony (典礼), his grandpa's car wouldn't work. Rather than2, the young boy thought up a plan.

The ceremony was taking place at Harris-Stowe State University. It was a six-mile walk away from his home. For Xavier, that was a walk he could3 and so he did. The trip, which lasted about two hours, was really long. To make matters worse, it was a(n)4 hot day, and there were holes in his shoes. He got so5 that he finally had to ask strangers for just a dollar to get something to drink. He even considered heading back home. Still,6 could stop him from achieving his goal.

Finally, Xavier not only made it to his graduation, but he also caught the7 of some very important people, including Collins Smith, the president of Harris-Stowe State University. "I was deeply8 by his actions," she said. As a result, she offered Xavier a four-year full ride scholarship (全额奖学金) to Harris-Stowe State University!

"9 you really want to get something, you can't lose your heart when you are in trouble," Xavier shared with young people like him. "10 your doubts, then work hard for it."

Chen Jiaorong is a 28-year-old girl from Shanghai. She walks along roads in Shanghai once or twice a week, looking for some things that were1.

Chen brings some of them back home. She also helps find new2 for the rest. Old furniture (家具), tableware (餐具), clothing, toys, and so on make up the list of Chen's "collection". When she sees such things on roads, she posts them online with photos and locations,3 showing people in need where to find them on the streets. Chen's action was described by others as "stooping". The word "stooping" means "picking up used objects and4 them". About 90 percent of objects in Chen's daily life come from "stooping". "Stooping is a green lifestyle. In this way, I can help save the earth. And another5 is that I can save a lot of money," Chen shared.

Do people like the same color? Of course not. Why? Because different people have different ideas. Black is one of the popular colors. People like it because it makes people look thinner. White is a clean color, but it is easy to get dirty. Blue is the colour of the sky and the sea. It often makes people feel cool. Green is a good color for our eyes. After doing homework for a long time, you can watch something green. Yellow is a lovely color, but if you are in a yellow room for a long time, you may get angry easily.

Colors are not only colors, they can tell much more. In English, when you have so many falls that your legs can be "black and blue" all over. When you are young, you can say you are "in the green". If you are sad, you "feel blue". If you are angry, you can say you "see red". When you find a big dog standing on your way, don't be "yellow"!

Colors are really interesting.

First, people in different countries have different ways of greeting each other. In Japan, people usually bow to greet others and show respect (尊重). In France and Italy, people often kiss on the cheeks. In France, they kiss 2—5 times in different places. In Italy, they usually kiss twice, right cheek first, then left.

Second, there are many differences in eating habits. Chinese people eat rice, noodles, vegetables and meat while Western people love bread, milk, salad and steak. People in many Western countries usually eat with a knife and fork, but Chinese eat with chopsticks (筷子). Indians even use their hands to eat! In China, if your guests have no food on their plates, it's polite to put food on their plates. In Canada, you pass food to guests, but you don't usually put food on their plates.

It's important for people to respect different cultural customs. That will help people from all countries understand each other well and live happily together.
