Once an Arab was travelling in the desert. When the sun went down in the west, he stopped and 1 his tent, made a fire and had a 2 meal. When night fell, he 3 down to sleep.

　　He had 4 fallen asleep when he felt a soft 5 on his. elbow (肘). He woke up to find that his camel (骆驼) had put his head inside the tent. The camel said, “Would you please let me keep my head in the tent to get warm? It's so cold outside I won't take up too much 6 .”

　　The Arab was a 7 man. “All right, do as you 8 .” he said. Then he turned on his 9 and went back to sleep.

　　It wasn't long 10 he felt a push on his shoulder. It was the camel again. “Dear master,” the camel said, “my head is quite warm now, but my neck is still cold. Do you mind 11 I keep it inside the tent, too?”

　　“ 12 ,” the man said. But this time he felt a bit 13 , as the camel had such a long neck.

　　No sooner had he shut his eyes 14 he got a harder push in his side. This time the camel said, “Will you please allow me to bring my front legs inside and warm them up a little?”

　　The Arab 15 over to one side of the tent. He made 16 as small as he could. It wasn't 17 comfortable, and sleep was now out of 18 .

　　Soon after that the camel gave him a rough push and said, “The tent is too small for the two of us. 19 , my two hind legs are still left in the cold. It is only 20 that you should leave the tent wholly to me.”

　　And with that, the camel kicked the poor man out.

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 more easily, but others move to get away from places that are too crowded.

When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移)is probably the migration of fish, which is called “salmon”. 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 crowded. 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(龙虾). 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 other times we don’t. Maybe living things just like to travel.
