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 the 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 mice. 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 lobsters（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.
4. Most animals move from one place to another at a certain time to ______________________ .
A. give birth B. enjoy warmer weather
C. find food more easily D. find beautiful places
