我们知道许多动物并不总呆在一个地方,鸟类、鱼类和其他动物在一定期限内从一地移往另一地.他们移动的原因很多,当寒冷的挑起到来时,许多鸟都迁移到温暖的地方觅食.大马哈鱼出生于新鲜的淡水水域但不远万里游到咸水中去并在那里生活.当大马哈鱼年老时,又会回到它的淡水出生地,然后寿终正寝.在北欧有一种老鼠,当这种鼠数量增多过于拥堵时,他们就离开山区的家迁往低矮的陆地.有时他们会一直移动到海边,当他们掉进大海时许多老鼠被淹死.近来,科学家们对一种龙虾的迁徙进行了研究.每年,当恶劣的气候到来时,龙虾们排成常常的一条队伍开始向海底走去,没有人知道他们为什么要这样做,也没有人知道他们将走向哪里.所以,有些时候我们知道为什么为什么人类和动物从一地迁徙到一地,但另一些时候我们不知道.也许生物只是喜欢旅游.

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.When cold weather comes, many birds move to warmer places to find food.The salmon 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. 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 (近来), scientists have studied the migration of a kind of lobster (龙虾). Every year,
when the season of the 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。
