　　Long, long ago there were a lot of donkeys. The donkeys worked hard every day. They had no time to play or to relax, but they never felt appreciated for the work they did.
　　One day two donkeys got bored. They wanted to live a comfortable life. So the donkeys went to see a wise old man. They told him their problem. The wise old man agreed that they worked too hard, and he wanted to help the donkeys. "I have an idea." he said.
　　"What is your idea?" asked the donkeys.
　　"I will paint you and no one will are donkeys," said the man.
　　The man went off to find some paint and he returned in just a matter of minutes. He had two pots of paint. One pot was filled with white paint, and the other black paint.
　　The old man first painted them white, and then painted black stripes(斑纹) over the  white paint. When he finished, the donkeys did not look at all like donkeys. "You no longer look like donkeys,” the old man said.  “Everyone will be fooled. I will call you something else, zebras. "
　　The zebras went to a field to eat grass. Now they did not have to work.
　　Soon, other donkeys saw the zebras. They asked the zebras where they came from. When the ' zebras told the donkeys their secret, the donkeys all rushed to see the old man.
　　"Mas into zebras, too," they pleaded. So the wise old man painted more donkeys. As he did, more and more donkeys came.
　　The old man could not paint fast enough. Soon the donkeys became impatient. They began to kict, and they knocked over the paint pots.
　　There was no more paint. The painted donkeys ran off to become zebras. The unpainted don- keys, because of their impatience, had to return to work.
　　This is why it is important to be patient.

　　There are two kinds of changes—chemical change and physical change.
　　In a chemical change, there is always a new substance formed. Breap water into hydrogen and oxygen is a chemical change. In each of the chemical change at least one new substance is formed. A change is not a chemical change if it doesn’t form a new substance.
　　Physical changes are very common, too. There are many examples. You can make a physical change by tearing a piece of paper into two, or by cutting a piece of iron with lathe(车床). Here paper is still paper, and the iron is still iron.
　　Another way of making physical change is dissolving something in water. When you dissolve salt in water, the salt disappears. You may think that a new substance has been formed. But really there is no new substance. The salt is still salt. You can still taste it. So the dissolving of anything is a physical change. 
　　When water freezes, the change is also a physical one. The water changes from liquid to solid, but it is still the same substance. That is why the freezing of anything is a physical change.
