仿生学是什么？它是一门学科，可我们的生活却与它息息相关，比如高速列车啊，飞机和雪地汽车都离不开它。
What is bionics? It is a subject, but our lives are closely related to it, such as high-speed trains, airplanes, and snowmobiles.
现说说高速列车吧，相信同学们都坐过，可它原来跑得并不快，原因？因为它的车头原来是方的，阻力很大，跑的一点也不快，后来，人们发现，翠鸟的尖嘴冲进水里叼鱼时，速度虽然很快，但一点阻力也没有。于是，人们把车头换成了尖尖的，速度足足提升了一倍。
Now let's talk about the high-speed train. I believe all of you have taken it before, but it didn't run very fast. What's the reason? Because its front end was originally square and had a lot of resistance, it didn't run fast at all. Later, people discovered that when the beak of the emerald bird rushed into the water to catch fish, although it was very fast, it had no resistance at all. So people replaced the front of the car with a pointed one, doubling the speed.
再比如说飞机吧，飞机的机翼经常抖动而坏掉，造成机毁人亡的惨祸。
For example, let's talk about airplanes. The wings of airplanes often shake and break down, causing tragic accidents such as plane crashes and fatalities.
大自然真神奇啊，人们用蝙蝠在夜里飞行的原理发明了无线电波，用企鹅在冰上健步的原理，发明了雪地越野车……其实只要你留心观察，大自然神奇的地方还有很多呢！
Nature is truly amazing. People invented radio waves using the principle of bats flying at night, and snow off-road vehicles using the principle of penguins walking on ice; … In fact, as long as you pay attention to observation, there are still many magical places in nature!
