有很多人都曾有过这样的想法:人的腿为什么不进化成两个轮子的模样?这个问题自然有生理学上的科学解释。然而,人类靠轮子运动的确已经有100多年的历史了,那就是汽车的贡献。最近,美国一家新概念运输公司推出了一款新型的可穿戴式电动车,让人可以直接套在两条腿上,可让人“变身”为靠两个轮子行走的生物。 Many people have had the idea that the human leg does not evolve into the appearance of two wheels. This question naturally has a physiologically scientific explanation. However, it is true that mankind has relied on wheels for over 100 years. That is the contribution made by the car. Recently, a new concept transportation company in the United States introduced a new type of wearable electric car, allowing people to put it directly on two legs, allowing people to “transform” into two-wheel-walking creatures.
