C
In Qinghai Province,a wolf gets fat by drinking milk! One day, a woman drives through the Kekexili National Nature Reserve. She sees a weak wolf and feels sorry for it. So she gives the wolf some of her milk. The wolf is happy.
The next day, when the woman drives by again, the wolf stops her. It wants more food. Then, other people hear about this and also give the wolf food. Finally, the wolf changes. It becomes like a beggar(乞丐). It wags its tail and rolls on its back to ask for food from people passing by. Now, people wonder if the wolf can go back to the wild and live on its own.
Wolves are apex predators. That means they are at the top of the food chain. They hunt other animals. But there are not many animals strong enough to hurt them in the wild.
However,human activities have a big effect on nature. The growing cities and roads bring animals into contact with humans. Some animals are faced with great danger. For example,the golden snub-nosed monkey, the Asian elephant and the South China tiger are in danger.
More people take hiking or camping trips into wild areas. Some people take nature's land to build cities,and they throw away food and plastic bottles. Sometimes we even start fires. As we enjoy nature's peace,we should remember that peace comes from the animals we love.
We are part of nature's balance(平衡). We should try to keep this balance and save those animals. And we should also stay away from dangerous animals.
