This includes thousands of types of plants, birds, insects, and mammals. Many of these cannot be found anywhere else. The rainforest is often called the “lungs of the Earth” because its plants produce about 20% of the world's oxygen. However,the Amazon is facing great danger. Every year, large areas of the forest are cut down or burned. People do this to clear land for farming, raising cattle, or logging. This destruction not only destroys animal homes but also affects the world's climate. Many organizations and countries are now working together to protect this amazing and important place.

B Plants are amazing living things.They can't move around like animals, but they have their own smart ways to live and grow. For example, the sunflower can turn its face to follow the sun across the sky. This helps it get more sunlight. Some plants, like the Venus flytrap, even eat insects! They grow in soil that has little nitrogen, so they catch insects to get this important nutrient. One of the most wonderful things about plants is photosynthesis.Using sunlight, water, and carbon dioxide, they make their own food and give off oxygen. This process supports almost all life on Earth. Plants also communicate with each other in some ways. When a tree is attacked by insects, it may send out chemicals to warn nearby trees. We depend on plants for food,oxygen, medicine, and many other things. We should all be thankful for these quiet but amazing friends. 1. Why does a sunflower turn its face?（ ） A. To look at people. B.

Its skin is actually black, but it has thick, white fur that helps it blend into the snow and ice. This is perfect for hunting. Polar bears are excellent swimmers.They use their large front paws to paddle and can swim for long distances in the cold ocean. They mainly eat seals. A polar bear waits patiently by a hole in the ice for a seal to come up for air. However,polar bears are now in danger because of climate change. The sea ice they depend on is melting. We must take action to protect these amazing creatures and their home. They are a true symbol of the wild and beautiful Arctic. 学科网（北京）股份有限公司 $
