Long long ago, a man had a cat which he loved very much. He thought it was such an unusual animal that he decided to name it Sky.
One day, a friend said to him, “Allow me to point out to you that there is something stronger than sky. I mean the clouds, for they hide (隐藏) the sky.” “You are right,” replied the man “From now on, I’m going to give my most unusual cat the name Cloud.”
Sometime later, one of his neighbors was drinking tea at his house. “Why do you call this unusual animal Cloud For there is something much stronger than the clouds. I mean the wind that blows away the clouds in front of it.” So from then on, the man called the cat Wind.
But a week had not passed when the leader of the town noticed this quite unusual cat. “Wind,” he said, “seems to me a name that is not worth the quality (质量) of this animal. The wind meets his master (主人) every day. I mean the wall that it cannot blow through.” “Ah, so,” said the owner of the cat, “my most beloved pet will be called Wall.”

例文 Trees are important
Hello, everyone. Today my topic is “Trees are important”.
Trees are very useful. First, trees can keep the air cool and clean, they can make our environment more beautiful and keep us healthy. Second, trees can take in harmful gases and produce oxygen for us to breathe. Third, the trunk and branches provide us with wood so we can use wood to make many things. For example, much furniture is made of wood. We can also use some trees in Chinese medicine to fight against diseases. Finally, trees can provide us with some food.
In short, trees are really helpful to us in many different ways. So it’s important for us to protect trees. First, we should stop cutting down so many trees and do our best to plant more trees. Second, we had better use both sides of the paper so that we can save wood.
That’s all. Thanks for your listening!
