2024年初中英语中考最新时文阅读训练 专题14动物植物 阅读理解 A Polar bear paws 北极熊的熊掌 ① Ice can be slippery and dangerous for humans to walk on, but for polar bears, it is easy to walk on ice. Scientists have figured out the reason. The pads(动物肉掌)on polar bear paws are special. They have small structures that are like little bumps(凸起). These bumps help polar bears hold on to the ice better. ②Scientists at the University of Akron, including Ali Dhinojwala, wanted to know more about polar bear paws. They compared the paws of polar bears to those of other bears, like brown bears and American black bears. Other bears also have bumps on their paw pads, but thoseon polar bear paws are taller. ③ The scientists also used a 3D printer to make models of the paw bumps. Next, they made snow in the lab and tested the models on the snow. They found that those taller bumps worked better on the snow and gave polar bears more grip. The paw pads of polar bears are smaller than those of other bears. They might let the bears save body heat. Extra grippy bumps make up for the smaller size of their paw pads. In November 2022, Ali's team shared these findings in a science magazine. ④ The scientists hope to study more than just bumpy pads. They will continue to learn about the paws and claws. This will help them know more about polar bears' non-slip grip. 1. What is Paragraph 1 mainly about? A. What polar bears are like. B. Why polar bears can easily walk on ice. C. How polar bears live.
