Human beings learn technology from nature. They tend to imitate it. It did take us a while to learn, though. However, not until the mid-twentieth century was the word "biomimicry (仿生学)" first introduced.
One of the first examples would be the invention of Velcro (魔术贴), a material that was born after a walk in the countryside by an engineer and his dog. On returning home, he found his socks were filled with little burrs (刺果). They were covered by many tiny hooks (勾). He used those qualities for some kind of fabric. And then Velcro was born.
A high-speed train used to create great noise while exiting a tunnel because of the air pressure. Eiji Nakatsu, an engineer and bird-lover, was inspired by the kingfisher's beak (鸟嘴), able to dive into the water at great speed with almost no friction, to create a new design. That's how the modern bullet train, much more efficient and quieter, was born.
Secondly, there would be the imitation of Nature's strategies and mechanisms. For instance, dolphins have mastered the art of sending out ultrasound (超声波) without disturbing each other. A team of researchers have analyzed the way dolphins adjust these frequencies.
Finally, there's the imitation of the efficiency within an ecosystem. For example, the street is full of tiny holes to empty water in flooding seasons and the foundations of buildings grasp the hillsides like the roots of trees.
A. One is the imitation of shapes.
B. People imitate forests to build cities.
C. For instance, birds taught people to fly.
D. He decided to get rid of these little burrs.
E. Then he bent down to inspect them closely.
F. Urban areas consume more energy than rural areas.
G. Based on the analysis, they designed a tsunami alarm system.

A. How do they affect us? B. Emojis are real pictures. C. Why are emojis important? D. The invention of emojis changed that! E. This means that emojis have created a new brain pattern in us. F. The first emojis appeared on Japanese mobile phones in the 1990s. G. A written message is black and white, but an emoji adds emotions to our messages. |
When you write a message or an email, you might put a smiling face or other pictures at the end to make the message more fun. These pictures are emojis (表情符号). {#blank#}1{#/blank#} Later, they were used on Apple's iPhone and Android phones. Now they are everywhere!
Emoticon or emoji?
Before emojis, there were emoticons, which can be made from the signs you can find on your keyboard, for example: for a smiley. Emoji is a Japanese word which means photograph. e ("picture") + moji ("character"). {#blank#}2{#/blank#} There are all kinds of emojis, from faces and weather pictures to things in the kitchen and animals.
What are emojis for?
In English, we have a saying: A picture paints a thousand words. For many people, an emoji is like a punctuation mark, or smiling at someone across the room. {#blank#}3{#/blank#} It is like the tone (语气) of voice when we speak on the phone, or gestures used in conversation.
{#blank#}4{#/blank#}
When someone speaks and looks serious, we try to look serious, too, and when someone smiles, we smile as well. This is how we show empathy (共鸣) and make friends.
But when we are online, we can't see the person's face and there is no emotion. {#blank#}5{#/blank#} Scientists in Australia have discovered that when we look at a smiley face online, the same parts of the brain start working as when we look at a real smiley face. Our mood changes, and we try to change our face to match the emoji.
