Reading for details
1.They are formed because of the unique karst landscape, which is made up of limestone (石灰岩),  a soft rock dissolving (溶解) in water. When rainwater flows through little cracks in the bedrock, the cracks slowly grow into tunnels (隧道) and then big caves, which can get too big, and the ceilings fall slowly, opening up huge sinkholes.
2.The newly-found one is 306 meters long, 150 meters wide and 192 meters deep, while in other parts of the world sinkholes might be quite subdued (压制的), only a meter or two in diameter.
3.It harbors a “well-preserved primitive forest” at the bottom, spanning (横跨) nearly three soccer fields in length, where researchers found prehistoric-seeming (类似史前的) trees up to 40 meters high and undergrowth (林下植物) which came up to their shoulders.

Chinese President Xi Jinping expressed his thought on ecological civilization by saying “Lucid waters and lush mountains are invaluable assets,” meaning that nature is a valuable treasure for humanity.

So, it is time for all of us to attach more importance to protecting the environment so we can live in harmony with the natural world.
