What do you imagine a real­life Iron Man would be like in the future? Activity 4: Consolidate and feed back. Fill in the blanks according to the text. Perfected over billions of years, nature's forms and functions 1.________(inspire) us to imitate it and develop materials and technologies 2.________ improve our lives, thus leading to the birth of bionics, 3.________ nature and technology intersect. 4.________ the term “bionics” officially 5.________(date) back to 1958, the practice is centuries old. Take Lu Ban, 6.________ carpenter in ancient China, as an example. He was engaged in bionics and produced a saw by 7.________(copy) the shape of a leaf's sharp teeth 2，500 years ago.

Scientists often need to go to great 9.________(long) to effectively combine nature and 10.________(innovate). The process of observation, data analysis, further exploration, and developing a new product or perhaps improving an existing one may take scientists years of trial and error to perfect the product. Activity 5: Warm­up for the next period. Preview the new words and find the English expressions of the following Chinese in the text. 1. 被嵌入……　　　　　　　　　 2. 抵消，对消 3. 适应……，与……合得来 4. 弥合差距 5. 完善产品 6. 多年的反复试验 7. 竭尽全力；不遗余力 8. 激发他们的创造力 9. 从事仿生学研究 10. 追溯到…… 11. 从……中获取灵感 12. 接受许多新颖的想法 Activity 1： Ⅰ. 1—5 CDBAD Ⅱ. 1. Inspired by observing the wings of butterflies covered with tiny diamondshaped structures that interact with light, causing some colour wavelengths to be cancelled out while intensifying and reflecting others, scientists have recreated microstructures and inset them into banknotes and produced a unique visual effect almost impossible to copy. 2. When the robotic suits are worn, they can greatly improve the mobility, strength and loadbearing capabilities of the wearer. Activity 2： 1. It means that human beings are full of curiosity naturally. At the same time, there are many unknown mysteries in nature that attract human beings to explore. 2. With the development of science, we will discover more secrets from clever nature. As we are working hard to find them and take advantage of them to benefit ourselves, nature is likely to offer answers to our most urgent questions. That is, nature not only provides our lives with a scenic backdrop, it could also prove to be our greatest teacher! Activity 3： A future reallife Iron Man would be able to bear more loads and move more flexibly with great strength. As soon as he starts his engines by himself, he bends his knees, and the next minute he is ascending into the air. He would be able to hover, defying gravity before he begins to fly up and down an ordinary street in any city and travels to any place all over the world freely. This is one of the future scenes of the reallife Iron Man in my mind. Activity 4： 1. have inspired　2. that/which　3. where 4.
