(新素材) As humans have a need to communicate, animals have it to send and receive messages as well.
But how do animals communicate? According to a study carried out in 1898 by a scientist called Char, there are usually three ways for them to communicate.
For example, if a monkey notices a snake, it will give an alarm call for the other monkeys to climb into the trees. If the monkey notices an eagle(鹰), it will send a loud noise to tell other monkeys to get close to the ground. The second way seems quite different. Those with a pet dog will easily know how a happy dog happily moves its tail. A cat that feels it is in danger will stand with its back high. Another type of animal communication takes place among some certain animals. For example, elephants and giraffes will touch their friends if they like each other. Horses also touch their noses together as a sign that they are comfortable with one another.
It is truly amazing to discover the nature's secret and exciting for us to take a step closer to the animal world. More and more countries have put much money and effort into further research on this. At the same time, plenty of different voices are appearing. Is it really necessary to waste so much money on something that may be meaningless to us humans?
All in all, every coin has two sides. We shall wait and see what this change can bring us in the future.
