任务型阅读
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.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
判断
all animals move when the weather gets cold
F,因为文章说的是大部分动物,不是所有的吧?
what is the main reason for birds fish or other animals to move from one place to another
我觉得是 to find food
翻译
Maybe living things just like to travel
我翻译的是 可能生物都喜欢旅行

你的答案是对的,至少我做的是这样的.
以下是百度翻译:
我们知道,许多动物不停留在一个地方.鸟类,鱼类和其他动物从一个地方移到另一个在某个时间.他们将为不同的原因：他们中的大多数将找到的食物更容易,但其他人移动远离的地方太拥挤.当寒冷的天气到来时,许多鸟类搬到温暖的地方寻找食物.有些鱼给出生在温暖的水和移动到冷水饲料.最著名的移民（迁移）可能是迁移的鱼,这是所谓的“鱼”.本鱼是天生的新鲜水但旅行好几英里的盐水.它花的生命.当它老了,它返回其出生地在淡水.然后它使出生和死亡.在欧洲北部,有一种老鼠.他们离开他们的家园时,他们变得太拥挤了.他们将下降到较低的土地.有时,他们将所有的滨海路,其中许多人被杀害时,他们坠入大海.最近（近来）,科学家们研究了移民的一种龙虾（龙虾）.每一年,当季的恶劣天气到来,龙虾进入一段线,开始步行在海底.没有人知道为什么他们这样做了,没有人知道他们去了哪里.所以,有时我们知道为什么人类和动物从一个地方移到另一个,但在其他我们不可能生活的事情就像旅行
百度的最后一句很明显翻错了:
也许只是因为生物喜欢旅行而已.
