How would you feel? Disappointed? Angry? Sad? At this moment you realize people, plants, and animals are all connected. We need each other to live, and bees are one of the best examples of this connection. Bees are very hard-working animals, and their greatest work is pollination. On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow. In fact, without their work, about 80 per cent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet. Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes. In order to store honey, they create honeycombs. Another interesting thing about bees is how they communicate. When a bee finds new food, it uses a dance to tell the others where and how far away the food is. Bees play an important part in the ecosystem of our planet. However, the number of bees is dropping, and scientists are worried. They need our help, and there is a lot we can do. Think about what you can do to protect one of the most amazing animals on earth. 知识点整理： without (prep.) 想象做某事 at this moment realize (v.) pollination (n.) pollen (n.) take action in fact for this reason store (v.) play an important part in the ecosystem of ... the number of ... 担忧；担心 protect (v.) .....from..... Section B-3a课文 The Blue Whale The blue whale is the largest and heaviest animal on earth. It can weigh as much as 200 tons. Many people like watching blue whales swim, and they think it is one of the most beautiful things to see. Blue whales live in all oceans except the Arctic Ocean.They eat a lot, but they eat some of the tiniest animals in the ocean. A blue whale can eat around four tons of these a day. Blue whales can live up to 90 years. When a blue whale dies at sea, it becomes food for many kinds of animals living in and around the sea. This food lasts for over a year and it helps to create a lively and healthy ecosystem. Blue whales play an important role in our world, so we must protect them. 知识点整理： 在地球上 weigh as much as ... except (prep.) the Arctic Ocean tiniest (tiny adj.) 活到（几岁） 在海里 many kinds of last for + 时间 create (v.) a lively ecosystem play a role in... 三、短语归纳(反复读） Section A 知识点 1. blue whale 蓝鲸 2. redwood tree 红杉树 3. in the world 在世界上 4. a folding fan 折扇 5. a/the symbol of ... ....的象征 6. bamboo forest 竹林 7. bamboo shoots 竹笋 注：shoot(s) 名词-嫩芽；动词-射击 8. bamboo baskets 竹篮 9. the fastest-growing plants 生长最快的植物 10. build house(s) 盖/建房子 11. make tools and instruments 制造工具和器具 12.
