There was a man. He had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them each on a quest(探索)in turn, to go and look at a pear tree that was far away. The first son went in the winter, the second in the spring, the third in the summer, 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 ,bent and weak. The second son said no---it was covered with green buds and full of promise. The third son said it was laden with blossoms and they smelt so sweet and looked so beautiful. The last son disagreed with all of them. He said it was ripe and drooping（下垂 ）with fruit, full of life and fulfillment.. The man then said to his sons that they were all right, because they each had seen but only one season in the tree’s life. He told them that they cannot judge a tree or a person, by only one season, and that the essence(本質(zhì)) of who they are---- the pleasure, the joy and love that come from that life---can only be measured at the end （蓋棺論定）,when all the seasons are up.    If you give up when it is in winter, you will miss the promise of your spring, the beauty of your summer, the fulfillment of your fall. Don’t let the pain of one destroy the joy of all the rest.
小題1:Why did the man sent his sons each on a quest?
小題2:When did the fourth son go?
小題3:What did the third son say when they came back?
小題4: Did the man agree with all of his sons?
小題5:Which season will you miss If you give up when it is in winter?

We know that many animals do not stay in one place . Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food easily, but others move to get away from places that are too crowed.
When cold weather comes, many birds move to warmer places to find food. Some fish give birth in warm water and move to cold water to feed. The most famous migration(遷移) of the fish, which is called “salmon(大馬哈)”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowed. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster(龍蝦). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go.
So, sometimes we know why humans and animals move from one place to another, but at others times we don’t. Maybe living things just like to travel.
