VIII. 根据短文内容完成下列各题
There was a man who had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them to go and look at a pear tree far away in turns.
The first son went in the winter. the second in the spring, the third in the summer, and the youngest son in the fall.
When they had all gone and come back, he called them together to describe what they had seen. The first son said that the tree was ugly. The second son said no. It was covered with green leaves, and full of hope. The third son disagreed. He said there were many flowers that
smelled so sweet and looked so beautiful; it was the most wonderful thing he had ever seen. The last son disagreed with all of them: he said there was lots of fruit on the tree, full of life and harvest(收获).
The man then explained to his sons that they were all right, but they had each seen only one season in the tree’s life. He told them, "You cannot judge a tree, or a person by only one season and its true nature -the pleasure, joy,
and love that come from that life can only be judged at the end, when all the seasons are up.”
If you give up when it's winter, you will miss the promise of your spring, the beauty of your summer ,harvest of your fall. Don't let the pain of one season kill the joy of all the rest. Don't judge a life by one difficult season.
