A(https://www.daowen.com)
The long trunk（象鼻）of an elephant is a wonderful example of skill．The neck of four-footed animals is usually long，to have them reach their food without difficulty，but the elephant has a short neck，to make him more easily support the weight of his huge head and heavy teeth.His long trunk lets him get his food easily.
The trunk of an elephant to him is what the neck to other animals.It is also a nose to him，for at the end of it there is an empty place like a cup, and in the bottom of the cup are two holes, and the animal smells and breathes through them.It is an arm and a hand too, so that it has been said that the elephant carries his nose in his hand, and it might also have been said that he breathes by his hand．
At the end of the trunk, there is a strange part, about five inches long, which forms a finger.With this finger the animal can pick up the smallest piece of money from the ground, and he has been taught to make marks like letter with a pen.The elephant has such great strength that he can knock down a man with it.
B
Everybody hates rats.But rats may soon be man’s new good friends.What happens after an earthquake? We send in rescue dogs.Why? Because they can smell people.Dogs save lives.They help rescuers to find living people.But dogs are big and they can’t get into small spaces.So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people.When this happens, the rat’s brain gives a signal.This is sent to a small radio on its back, and then the rescuers follow the radio signals.When the rat’s brain activity jumps, the rescuers know that someone is alive.The rat has smelled that person.
Although there are already robots which can do this job, rats are better.Robots’ noses don’t work well when there are other smells around.Rats are good at that.Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished.But a scientist says, “It would be great.A rat could get into any place we couldn’t get to, and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building(but only after an earthquake, of course).
