In science, people copy ideas from nature to solve problems or to create products. This is called biomimiery(仿生学). Its influence can be seen in many everyday products.

Nearly ten years ago, swimwear was influenced by nature. The Speedo Fastskin, a swimsuit, was seen at the Beijing Olympics and worn by 28 of the 33 gold medal winners. The technology is based on the rough patterns on a shark's skin, which allows the shark to swim faster.

Protecting astronauts' eyes from the sun's rays is very important but protecting their eyes from other dangerous radiation is also necessary. Scientists studied how eagles clearly recognize the animals they want to eat. They discovered that eagles have yellow oil in their eyes which fihers(过滤) out harmful radiation and allows them to see very clearly. They copied this oil and it is now used by astronauts and pilots in Eagle Eyes glasses. Besides protecting eyes from all the dangerous rays, these sunglasses also improve seeing in different weather conditions such as fog, sunlight or just normal light.

In another development, a car company has developed a new car which is based on the shape of the boxfish. Engineers chose to copy the boxfish skeleton(骨架) to make their Bionic Car because of its strength and low weight. Tile boxfish's bony body protects the animal's insides from injury in the same way as a car needs to protect the people inside it. This shape also means the car has less air resistance and so uses less fuel.

3.What special feature(特征) of eagle eyes was copied to make sunglasses?

5.Do you think biomimicry will be more common in the future? Why or why not?
