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.
①The surface of the earth falls slowly.
②The cracks slowly grow into big holes.
③Rainwater runs through cracks in the bedrock.
How do you look after your cat? Introduction The first step to becoming a good cat owner (主人) is to choose the right kind of cat. It is how a cat behaves that is the most important, not what she looks like or how old she is. She is going to be your best friend. You will spend a lot of time playing together. But remember, you need to look after her every day. Not just to start with, but for all her life. Understanding your pet By watching your cat closely, you will learn her special way of talking. From the movement of her tail or ears, you will see if she is happy or sad. And you will soon understand what she is saying when she miaows. Caring for your pet You will only be your cat's best friend if you care for her properly.You will need to make sure that she eats the right foods, always has water, and can get plenty of exercise every day. You will also have to bathe(给……洗澡) her often and spend some time training her. |
Do a science experiment to see how rain forms.You will need:a glass jar (罐),hot water,a plate and ice cubes (冰块). What happens in the jar? Hot water makes warm,wet air called steam (水蒸气).Steam rises up to the cold plate.The cold air changes the warm steam into water.Then heavy drops of water fall. |
What happens in the sky? The sun heats the water.The warm,wet air rises up into the sky.If the warm,wet air meets the cold air,rain clouds form.When the clouds have enough water,the drops fall to the ground as rain. |
