There was a man who had four sons. He hoped that his sons could learn not to judge (评价) things too quickly. So he gave his four sons a task, asked each of them to go to see a pear tree in different     1     .

The first son     2     in winter, the second in spring, the third in summer, and the youngest in autumn. When all of his sons returned home, he called     3     together to describe what they had seen.

The first son said the tree was ugly     4     it didn’t have leaves. It stood alone on the ground. The tree was hopeless.

The second son said it was not like that, the tree was covered with green buds (芽) and full of     5     .

The third son didn’t think so , saying that the tree was full of flowers and they looked so     6    . He had never seen such beautiful flowers before.

The last son     7     with all of them, saying that the tree was filled with     8    . The tree was lively.

The man told his four sons that they were all     9     , because they only saw the tree in one season. He told his sons that they could not judge a tree or a person     10     by one season. Only when all the seasons was over could they know a tree or a person completely .

We can learn more from this story. If we just     11     in winter, we will miss the hope of spring, the beauty of summer and the harvest (丰收) of autumn in our life.
