We call it the polar bear because it lives near the North Pole. It is the largest meat-eating animal living on land in the Arctic. It is about 2 to 3 meters long and weighs about 450 kilos. It has a very good sense of smell. It can sniff out a dead animal from 20 kilometers away. Polar bears are good swimmers. They can swim for many hours to get from one piece of ice to another. Unfortunately, the world is getting warmer. The ice is melting (融化). Polar bears have to swim further and further to find food. Sometimes they get so tired that they drown (溺亡). Moreover, because they run out of food on land, they sometimes come into human villages looking for food. This puts both humans and bears in danger. Scientists say that if we don’t keep global warming under control, polar bears might no longer exist in the wild by the end of this century. We must act now to protect these gentle giants. 1.

It tells stories about how wild animals communicate. Unlike traditional lectures, this audio book uses 3D sound effects. Listeners can hear a wolf howling in the west or a bird singing in the east. The creator, Dr. Smith, said he wanted to satisfy young people’s curiosity about nature. “When I was a child, I used to sit quietly by the pond. I watched how a swan accompanied her babies. Those soft moments gave me great warmth. I hope this book can bring that experience to everyone,” he said. The book also covers serious topics. It explains how pollutants kill marine life and how cutting down forests leads to unbalanced ecosystems. Dr. Smith suggests that we should treat animals gently. “If we lose our habitats, we fall ill just like animals,” he warns. 19.

Part 5 Writing（写作 满分10分） 范文： Dear Tom, Thank you for your letter. I’m glad that you care about wild animals. To protect them, here is some advice. First, don’t buy things made of animal fur or ivory, because many animals are killed for these products. Second, we should stop cutting down forests so that animals won’t lose their habitats. I believe if everyone tries to help, we can keep the balance of nature and live peacefully with wild animals. What do you think of my ideas? Yours sincerely, Li Hua 学科网（北京）股份有限公司 $
