Once upon a time, there was a man who had four sons. One day, he told 1 of his sons to go and see what a pear tree looked like during winter, spring, summer and autumn. Although the sons felt strange about their father's 2 , they went to see the pear tree. After a 3 , the father got them to come together and asked them what they had seen.
The first son answered that the tree had been bare（光秃秃的） and 4 .
The second son said, "No! It was covered with new 5 leaves. The tree had bright hopes."
The third son 6 his head, and said, "No! The pear tree was full of flowers. They smelled so sweet and 7 so beautiful."
"There were many pears 8 no flowers on the tree," the fourth son disagreed, "I saw the joy of a good harvest（丰收）."
The man then said to his sons that they were all right. They got 9 answers because each of them had seen only one season in the life of the pear tree.
"You cannot judge（评判）a tree, a person or your life by just one season. If you 10 in your winter, you will miss the hope of your spring, the beauty of your summer and the harvest of your autumn."
