①Have you ever thought about what’s more important, looking fashionable or feeling comfortable? You might have noticed many people choosing style over comfort and some even go to extremes (极端) to follow fashion. But we should remember: being fashionable isn’t everything. It’s more important to be healthy.

②Some people believe that they need to be a certain size to look good. So, they start extreme diets (日常饮食) that are not good for their health. They might not eat meals or eat too little, which can make them feel sick. Is it a healthy way to live?

③Also, many girls wear shoes with very high heels. They might think high heels make them look taller. But these shoes can actually hurt their feet and make it hard to walk comfortably, and it can increase risks of falls. Some even wear tight (紧的) clothes that influence blood circulation (循环), making it hard to breathe. Should we put fashion over comfort and physical health?

④Besides, some boys and girls spend a lot of time and money changing their hair color. The material they use is usually harmful to their health. To make their hair straight or curly, they also use tools that are hot enough to burn their hair. But using these tools too often or at very high temperatures can make the hair dry or even burnt. Is it really worth it to risk our health, spending so much time and money?

⑤So, let’s rethink what’s really important. Is it fashion or is it our well-being? Clothes or hairstyles don’t tell us anything about a person’s character. Instead of spending a lot of time choosing clothes, we could use that time to do fun things with friends. And instead of following extreme diets, let’s eat properly and exercise regularly. Remember, your worth is not decided by your appearance, but by who you are as a person.

If you have seen the movie Journey to the Center of the Earth (《地心历险记》), you may wonder about the underground forest world. But such worlds can really be found in real life, too!

In early May 2022, a team of Chinese scientists and explorers found a large sinkhole (天坑) in Leye county, Guangxi. It is 306 meters long, 150 meters wide and 192 meters deep. “It didn’t take us long to reach ground to walk on at first. We soon realized that we were nowhere close to the bottom of the 192-meter-deep sinkhole.” Li Xinchen said. They also found trees up to 40 meters high and plants that came up to their shoulders, which makes it hard for scientists to walk in the forest. For them, the underground forest is almost like a spider web (网).

According to Xinhua News Agency, the local people in Leye county are no strangers to sinkholes. The county is called “the museum of sinkholes” where people have found 30 sinkholes so far. These sinkholes are formed because of the special karst landscape (喀斯特地貌). Karst is an area of land made up of limestone (石灰岩), which is a soft rock that can be easily mixed with water. When rain water flows through little cracks (裂缝) in the bedrock, the cracks are slowly enlarged. Over time, as the underground structure of the land becomes too weak to support the surface (表面) of the earth and then it falls slowly, opening up huge sinkholes. What’s amazing is the great size of China’s sinkholes.

“In China, they have this unbelievable karst with large sinkholes. In other parts of the world sinkholes might be far more undersized, only a meter or two in diameter (直径),” US researcher George Veni told Live Science. Sinkholes don’t just look cool, they are gifts of life. Many of them are home to ancient plants, animal and microbe (微生物) lives. They also provide water for 700 million people worldwide.
