答案

参考答案:

汉代的一种谪戍制度,因规定应强制服役的七种人,故名。讁同谪,即谪发,始于秦。据《汉书•武帝纪》,天汉四年(前97),发天下七科讁及勇敢士等出朔方击匈奴。颜师古注引张晏曰:“吏有罪一,亡命二,赘婿三,贾人四,故有市籍五,父母有市籍六,大父母有市籍七,凡七科也。”七科讁之名仅此一见。

     What do you know about the sea? You may have seen it. Some of us have swum or bathed in it. It

looks beautiful on a fine sunny day and it can be very rough when there is a strong wind. What other

things do we do about it? Of course, the sea is very large. In the world there is more sea than land. The

sea covers three quarters of the earth. The sea is also very deep in some places. It is not deep

everywhere; some parts of it are very great. At one spot, near Japan the sea is nearly 11kilometres deep

just think of it, the highest mountain in the world is only 9 kilometres high! If you have swum in the sea,

you know that the water is salty. Rivers carry salt from the land into the sea. Some parts of the sea are

more salty than other parts. Do you know the Dead Sea in Arabia? It is very salty. Swimmers cannot

sink in it! Fish cannot live in the Dead Sea. It is a strange sea. In most parts of the sea, there are a lot of

fishes and plants. Some live near the top of the sea. Others live deep down. No sunlight can reach the

depth of the sea. So it is completely dark. Strange fishes live there. Some are blind. Some have their own

lights. Some have great jaws(嘴巴).With their great jaws, they swallow fish larger than themselves.

The sea can be very cold. Deep sea divers know this well. At the top the water may be warm. Then as

the divers go down, the sea becomes colder and colder.

    Many scientists are now making a study of animal and plant life in the sea. They hope to find new

resources for mankind.
