When we are talking about animals in China, the most precious (珍贵的) animal we would think of is the panda. In fact, we have one kind of bird as precious as the panda,1many people don't know much about it. The bird is called crested ibis (朱鹮) . It is as2as snow with a red face and looks very beautiful. It is also in danger like the panda.
Crested ibises3in tall trees by small rivers or rice fields. They look for small fish and4small animals for food. About one hundred years ago,5crested ibises lived in China, Russia and Japan. Later, as they lost their homes,6them was getting smaller and smaller. Between 1965 and 1980, people didn't see any of them living in the wild. Luckily, on May 23, 1981, scientists7seven of them in the south of Shanxi Province. 8protect crested ibises in the wild, the Chinese government is setting up nature parks and developing other plans. Now scientists are doing a lot of research to help them to9more babies. Today there are about 1,500 crested ibises living in the wild. Zoos and research centres10after about 500 crested ibises.
1970 was World Conservation (保护) Year. The UN wanted everyone to know that the world was in danger. They hoped something could be done.
Here is one example of the problem. At one time there were about 1,300 kinds of plants, trees and flowers in Holland, but now only about 866 are left. The others have been destroyed by modern people and their science. We are polluting earth, air, water and everything around us. We can't live without these things. If things go on like this, we shall destroy ourselves.
What will happen in the future? Perhaps it's more important to ask "What must we do?". More and more young people have known this. Many of them are helping to save our Earth. For example, they plant trees. In a small town in the United States, a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conversation through an album called "No One's Gonna Change Our World". It includes songs of Cliff Richard and other singers. The money from selling it will help to conserve tigers, elephants and pandas on Earth.
A young man from a village called Nawalapitiya married a young woman from Maiyuwa, a small village. They lived with the man's big family—his parents, his brothers, their wives and children. The family kept an elephant, in which the woman soon took a great interest. Every day she fed it with fruit and sugar.
Three months later, having quarreled with her husband, the woman went back to her parents' home. Soon the elephant refused to eat and work. It appeared to be ill and heartbroken. One morning after several weeks the animal disappeared from the house.
It went to the woman's home. On seeing her, the elephant waved its trunk and touched her with it. The young woman was so moved by the act of the animal. So she went back to her husband's home.
John James Audubon loved all kinds of birds. He spent his life studying them. He painted all the birds of North America.
John James Audubon was born in Haiti in 1785. When he was a young boy, he moved to France with his family. His father was in the French Navy. He had a farm in the United States. When John was 18, his father sent him to the farm, hoping John would take care of it. But John didn't want to do that. He wanted to hunt, fish, and draw birds. John drew lots of pictures of birds. He wanted to make them look real.
In 1808, John married Lucy Bakewell and they moved to Kentucky. John and a friend went into business there. They ran a shop. John really didn't like working in the shop. The business soon failed. John wanted to paint full-time. Lucy agreed to help. She got a teaching job to support the family. By that time, they had two young sons.
John wanted his bird paintings made into a book. He finally did find someone to print his bird pictures in a book. Many people wanted John Audubon's book. Although his book was a great success, John wasn't happy with it. He wanted to show every bird found in North America. By 1838, John finished a great work. It wasn't just one book. It was an amazing set of four books called The Birds of America. It had many paintings. Today, these paintings are very famous.
Everybody hates rats. But rats may soon be man's new best friends.
What happens after an earthquake? We send in rescue (援救) 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 space. 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," says a scientist. 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 fantastic. A rat could get into space 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).

some facts all their lives make friends with on their feet give birth to |
People already know a lot about animals. However, there are still some things about animals that may surprise you. Here are about animals you probably didn't know.
Cows do have best friends and feel stressed when they are separated. Scientists have found that cows are very social animals and that a cow always other cows. When a cow is with its friends, it feels relaxed, compared with when it is alone.
During a breeding season, a male penguin will offer a small stone to a female penguin as a gift. If she takes it, they will become partners. When the female penguin lays an egg, she and her partner may carry it , because some penguins don't build nests.
Crocodiles (鳄鱼) swallow (吞) stones. Crocodiles always swallow their food instead of eating it like other animals. They swallow stones which break the food into very small pieces in their stomachs. These stones may stay in their stomachs .
Elephants use plants to treat pain or other illnesses. Scientists once found a pregnant (怀孕的) elephant in Africa who ate a kind of plant which was not part of her normal food. Four days later, she a baby elephant. The same plant was used by the local pregnant women.
