They live in the sea and eat small fish and other sea life. One interesting fact is that whales can jump high out of the water. Another interesting fact is that they can sing songs. Therefore, many people around the world love them However, some kinds of whales are in danger because humans catch them for meat, fat and oil, and use whale parts to make things like candles and soap. What’s more, water pollution gets more serious and human activities cause more problems, whales cannot find enough clean place to live and they are having fewer babies. We should protect whales from water pollution.

Scientists say it’s ____4___ because of the use of pesticides (农药). They destroy the places that insects live in. What would happen if all insects died out?

We should teach them 10 environment at an early age. 六、任务型阅读(人与自然——自然生态) （核心素养——学习能力）（跨学科——仿生学） 向动物学习 Nature has many ways to solve problems. We humans learn a lot from animals and plants in nature. There is a science about how we copy great ideas from animals and plants to create helpful products. It is called biomimetics (仿生学) . Some animals such as this sugar glider have wing-like structures (结构) to help them fly from tree to tree. When they jump, they spread out their arms and legs to help them fly down easily. Wing-suits, a kind of clothes, can let people experience flying. The idea of these clothes comes from the sugar glider. Some animals have structures used for self-protection. An armadillo has a hard cover that can protect it from other dangerous animals. When an armadillo feels that it is in danger, it will change into a ball. Once the dangerous animal goes away, it comes out of the ball. The armadillo has taught people to create a backpack with a hard surface. The surface of the backpack protects things inside from being broken. Plants have helped people come up with amazing inventions, too. Perhaps the best-known example is Velcro (尼龙搭扣) . It includes two pieces of cloth. They stick to each other when they are pressed together. Velcro is used on everything from handbags to clothes. The idea of Velcro is from burrs (带芒刺的小果实) of a plant. They have special structures to allow themselves to stick to people’s clothing or hair. They are taken to other places in this way. From these examples, we can see biomimetics is widely used in our daily life. What other problems will nature help us solve in the future? Let’s wait and see! 1、2题完成句子； 3-5题简略回答问题。 1. We humans learn a lot from ______________. 2. The sugar gliders spread out _________________ to help them fly down easily. 3.

Take a close look at the world of insects (昆虫), you’ll discover many unbelievable things. Consider butterflies, for example. They have beautiful, colorful wings, and strong, fantastic flying skills. On summer days, you always see them flying freely over flower gardens and wild fields. But, did you know how butterflies become the flying insects? It’s one of the amazing things of nature. In the beginning, female butterflies lay a small and colorful egg on a leaf of a plant. It's hard to believe that the egg will become something completely different in a few days. It becomes a walking insect. This insect is called caterpillar. It now has legs, eyes and a large body. A new life began. The caterpillar can eat, walk and see. But it is still not a butterfly. Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket (保护层) and goes to sleep. This stage is known as the “pupa (蛹)” stage. After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the wings fill with blood, and the beautiful, colorful butterfly spreads its wings and flies away. After a few weeks, this adult butterfly lays her eggs, and the cycle begins all over again. This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things. 1.
