The salmon(大麻哈鱼) is a very strange fish.　 It is born in a river.　 But the young salmon takes 2 years to swim down the rivers towards the Pacific Ocean.　 For another 2 years it lives in the sea and becomes full grown.　 Then it returns to the river where it was born.

A grown-up　 salmon weighs about 25 pounds and is nearly three feet long.　 The female salmon will not lay the eggs(产卵) in the Pacific Ocean.　 When it is almost time to lay them, both male and female salmon begin a great journey. 　Each salmon is heading for the river where it was born.　 A salmon may be a thousand miles from where its life began, yet it is able to return to that place.

As the salmon swim, larger fish attack(袭击) them.　 The salmon are food for some other fish.　Some are caught by fishermen.　 The salmon that are left keep swimming.

After they enter the rivers, they head upstream(向上游).　 If rocks and waterfalls(瀑布) are in their way, the salmon leap(跳) over them.　 A salmon can leap up a fall as high as ten feet.　 It leaps by swimming at full speed under water, then rising to the surface.　 Almost the whole body of a salmon is made of muscle(肌肉).　 It is these powerful muscles that make the salmon fit for fast swimming, turning quickly, and leaping high out of the water.

Some reach their river in summer, others in the early autumn.　 They have come hundreds, even thousands of miles and it has taken them weeks and months.
