Canadian Geese are large blue and white birds. When autumn comes, they have to fly south where the weather is warmer. The winters are so cold in Canada that the birds will die if they stay there.
Last spring, Bill Lishman found sixteen young Canadian Geese on his farm. They had lost their parents. Bill thought, "These young birds won't know what to do in the autumn." He had a small plane and he decided to teach the birds to follow him. All through the summer, he went on short trips in his plane and the young geese flew after him.
When the cold weather arrived in the autumn, Bill flew to Virginia in the United States, 600 miles south of his home in Canada. The geese followed him all the way. Bill left the geese in Virginia and he returned home.
This spring, Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia to get them. He looked for them for two weeks, but he couldn't find them. When he arrived back home, he found the geese waiting for him. They had found their way home without him!
We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?
We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. {#blank#}1{#/blank#}We take minerals (矿物) from the ocean. We can get salt by evaporating (蒸发) seawater. {#blank#}2{#/blank#}such as gold. {#blank#}3{#/blank#}Seaweed (海草) becomes food of many kinds—even candy and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can't drink ocean water. {#blank#}4{#/blank#}But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. {#blank#}5{#/blank#}Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.
A. Other gifts, such as seaweed, can be also got from the sea. B. Huge as it is, the ocean can't hold all that we pour into it. C. Along with salt, other minerals are left after evaporation. D. We even use their bones (骨头) for fertilizer (肥料). E. Some of its contents (所含物) may cause illness. |
