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(迁移) of the fish, which is called “salmon(大马哈)”. 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(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 others times we don’t. Maybe living things just like to travel.

What do you think of the most important inventions in the world? The TV? The printing? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.
One of the simplest(最简单的) inventions is the toilet(冲水式马桶). Before toilets, waste ran into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.
Animal food is another important invention. Before the invention, most animals were killed（杀死） every autumn because there was not enough food for them in winter. After hay (干草) became a kind of common animal food, animals could live through the long winter. The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the world would be difficult for the people above 45.
