We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They’re in their shells ---sleeping .

Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep.

In spring the snail wakes up. Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can’t see very well. Its eyes, at the ends of the top feelers are very weak. But its sense of smell is very strong. It helps the snail to the new greens. Then the snail’s little mouth goes to work.

A snail’s mouth is no longer than the point of a pin(针). Yet it has 256,000 teeth! The teeth are so small that you can’t see them. But they do their work.. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones.

Mostly, a snail looks for food at night .But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.

Many years ago, there was an old man who had four sons. He wanted his sons to learn not to judge(判断) things too quickly. So he told them to go and look at a pear tree. It was far away from his home. The first son went in winter, the second in spring, the third in summer, and the youngest son in autumn.
When the sons came back, the old man asked them to say what they had seen.
The first son complained the tree was ugly. The second son said the tree was covered with buds and full of hope. The third son said the tree was full of green leaves. They looked so beautiful, and it was the most wonderful thing he had ever seen. The youngest son said that the tree was bowed down with heavy fruits. It was full of life and fulfillment(收获).
The man explained that all of his sons were right, but each of them had seen just one season of the tree. He told them that they couldn’t judge a tree or a person by only one season. "If you give up when it’s winter, you will miss the hope of your spring, the beauty of your summer, and the fulfillment of your autumn." said the old man
It is true that we shouldn’t let the hard season break the happiness of the other seasons. Never give up during the difficult days and better times are sure to come some day.
