托福TPO/【学术讲座】#20听力原文What is the talk mainly about?【新东方在线】

仿生学是人类为了创造新发明而向自然界学习并进行模仿的一种实践。

Biomimicry is the human practice of learning from and imitating things found in nature in order to create new inventions.

通过这种方式，科学家和工程师能够创造出既高效又可持续的创新解决方案。

This way, scientists and engineers can create innovative solutions that are both efficient and sustainable.

仿生学的一个著名例子是一种广泛使用的紧固系统的发明。发明者的灵感来源于植物上的牛蒡刺粘附在他狗的毛发上的方式。

One well-known example of biomimicry is the development of a widely used fastening system.The inventor was inspired by the way burrs, uh thorns, from plants stuck to his dog’s fur.

通过复制从他狗毛上取下的牛蒡刺上的微小钩子，他创造了这种新型紧固系统。

By replicating the tiny hooks found on the burrs he removed from the dog fur, he created the new fastening system.

另一个例子是基于白蚁建造的结构的通风系统而设计的节能建筑。

Another example is the design of energy-efficient buildings based on the ventilation system of structures created by termites.

白蚁是生活在地面上的昆虫，它们使用不同的材料建造土丘并在其中生活。白蚁丘拥有复杂的通风管道网络。这些通风管道能够维持稳定的内部温度，这一特点可以在人类建筑中进行模仿。

Termites are ground-dwelling insects that use different materials to create hills, or mounds, in which the termites live.Termite mounds have a complex network of vents.The vents maintain a stable internal temperature, which can be emulated in human architecture.

仿生学也可以应用于可再生能源领域。例如，研究人员正在开发以座头鲸的鳍状肢为模型的风力涡轮机叶片。这种独特的鳍状肢形状能够减少阻力并提高效率，从而实现更高效的风能捕获。

Biomimicry can also be applied to renewable energy.For instance, researchers are developing wind turbine blades modeled after the flippers of humpback whales.The unique shape of the flippers reduces drag and increases efficiency, leading to more effective wind energy capture.

What point does the speaker make about termite mounds?

What does the speaker imply about wind turbine blades that are being developed?
