Karen lived with her parents in the Karoo Basin of South Africa. The Karoo was famous for plant and animal fossils(化石). Karen’s father was a paleontologist(古生物学家), and Karen enjoyed looking at the dinosaur bones in his office. She hoped to discover her own dinosaur someday.

Every summer, Karen’s father invited paleontologists from around the world to the Karoo. As they hiked through the dry land, he would show them fossil samples(样本) within the layers of sedimentary rock(沉积岩) and ash.

This summer, Karen asked her father if she could go along on the hike. He agreed, but he asked her to stay close by. As they drove to the trail(小径) , Karen’s heart beat quickly with excitement. There were so many places to visit.

The hike was interesting, but Karen was too curious to stay on the trail. Without asking, she ran down into a nearby ravine(峡谷) and looked among the rocks. Then, she heard her father’s voice calling to her. She ran up the side of ravine. Suddenly, she spotted something white and shiny.“Dad!”she shouted excitedly.

Karen’s father stood at the top of the ravine with the other people. They looked worried until Karen pointed to the shiny object. All the paleontologists examined it. They nodded to each other in surprise. It was the skull(骨头) of a dinosaur nobody knew about! The paleontologists took pictures and shook Karen’s hands. Her father smiled, “Karen,” he said. “You are now the youngest paleontologist in the Karoo!”

Free-diving is diving underwater, holding your breath, without the use of equipment. In ancient times people had to free-dive to get food, such as fish and shellfish. Free divers also c 1. treasures lying at the bottom of the ocean. The Mediterranean Sea, south of Europe, had many trading ships passing through. Often ships sank, sometimes because of storms. They would swim down to the shipwreck and try to lift the most precious pieces. In modern times, free-diving is part of many different a2.such as underwater photography and spearfishing. Sports such as underwater football, rugby and hockey also involve free-diving.

The most dangerous free-diving is practised by a small group of extreme sportsmen and sportswomen who swim very deep. They aim to go to great depths and d3. for a long time on a single breath, wearing only a wetsuit. Deep under the water it is cold and black. The weight or pressure on your body is much h4. than that at the surface. That weight, and going so long on only one breath, can cause a person to become unconscious(无意识的)because of a lack of oxygen, and then die.

Why do people want to take part in a sport that is so dangerous?

You need to be fit to swim so deep, but you also need to be very strong mentally(精神上). At first it is difficult to sink. You have to stay c5. and even slow your thinking. But finally the air is pushed from your body, and you start to sink. It is as if the water were d 6. you down. This is a very peaceful feeling.

Natalia wrote many poems about her love of being in the deep blue ocean. She felt at one with nature there, as if in an ancient space. She would go into a deep state of being quiet and thinking before she went into the water. She would leave b7.her the stress of life, which she called “surface fuss”. According to Natalia, when you stop breathing, most of your body’s functions stop. It is as if time itself stopped.
